Answer:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
I Hope this will help you if not then Sorry, Have a wonderful day !Which statement about the genetic code is false?
A. There is no punctuation or spacing between codons.
B. Codons are composed of sets of three nucleotides.
C. Every amino acid is specified by a single codon.
D. The genetic code is almost universal, but not quite.
The statement 'every amino acid is specified by a single codon' about the genetic code is FALSE (Option C).
The genetic code refers to the process by which the heritable information is passed from the DNA sequence to RNA during transcription, and then from RNA to protein during translation.The genetic code is said to be redundant because there are amino acids that can be encoded by more than one codon.For example, the amino acid leucine can be specified by four different codons (CUU, CUC, CUA, and CUG).In conclusion, the statement 'every amino acid is specified by a single codon' about the genetic code is FALSE (Option C).

II. Homologous chromosomes pair up in the center of the cell
III. Spindle fibers separate homologous chromosomes
IV. Chromosomes become shorter and thicker
A. I, II, III, IV
B. IV, III, II, I
C. II, III, I, IV
D. IV, II, III, I
What is Meiosis
Meiosis (listen); from Ancient Greek'lessening', since it is a reductional division) is a special type of cell division of germ cells in reproducing organisms that produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Additionally, before the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilization, the haploid cells produced by meiosis between a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.
Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

The second generation of purebred cross of -hom-ozygo us recessive organism, with a —hom-ozygous dominant organism, contain a ratio of approximately _______ expressed dominant traits to recessive traits.
A. 2:1
B. 1:1
C. 1:3
D. 3:1
Answer:
D. 3:1
Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.
EVOLUTION CONNECTION The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals
Answer:
Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.
They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.

Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to the structures they supply. are found in the C6-T4 area of the vertebral column. extend through the sacrum. do not exist in humans.
Answer:
The correct answer is: do not enter into a plexus and directly connect to the structures they supply.
Explanation:
The anterior rami of the thoracic spinal nerves from T1 to T11 give birth to the intercostal nerves, which are part of the somatic nervous system.
The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, directly connecting to the structures they supply.
The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
Mike was adopted, and his biological family history is unknown. Although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. Mike has heard about commercial laboratories that can compare segments of your DNA to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. The results of these types of tests are highly inconclusive. If Mike’s DNA showed that he shares similarities in a segment of DNA with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. These tests can cost more than $2,500 and are not covered by many insurance companies.

he heme prosthetic group consists of protoporphyrin and an iron (II) ion. is the reason for cooperative binding of O2 by hemoglobin. is found only in myoglobin and hemoglobin. is the reason for cooperative binding of O2 by myoglobin.
Answer:
The correct answer is ''consists of protoporphyrin and an iron (II) ion.''
Explanation:
The heme group makes up the prosthetic (non-protein) group of hemoglobin and is responsible for its characteristic red color. It is composed of protoporphyrin IX, in the center of which is the ferrous ion (Fe+2). Protoporphyrin IX, in turn, is composed of four pyrrolic rings. The heme group is synthesized by the mitochondria, where protoporphyrin IX binds with the ferrous ion, before being released into the cytoplasm. The heme group is released in erythrocyte lysis, thus obtaining unconjugated or indirect bilirubin.

B.Identification and binding of RNAP on to the promoter sequence
C.Conversion of open initiation complex to closed initiation complex
D.Synthesis of RNA after the formation of open initiation complex
Answer
D
The transcription factors and RNA polymerase form a complex called the transcription initiation complex. This complex initiates transcription, and the RNA polymerase begins mRNA synthesis by matching complementary bases to the original DNA strand.
Erythrocytes have no nuclei. Without nuclei, erythrocytes can carry a higher amount of haemoglobin explain how this is an advantage in exchanging and carrying oxygen
Answer:
The correct answer is - hemoglobin binds with respiratory gases such as oxygen so more hemoglobin will carry more oxygen .
Explanation:
Red blood cells have adapted the trait of having no nucleus for several reasons but the major reason is to increase the amount of hemoglobin so this can carry more oxygen to various parts of the body from lungs. If there will be more hemoglobin then it will allows RBC to transfer more oxygen.
Hemoglobin is the respiratory pigment that has four heme group, containing iron ion, arround globin group, each iron ion in the heme can bind to one oxygen molecule; So one molecule of hemoglobin can transport four oxygen molecules as it binds with oxygen.
The immunoglobulin light chain does not have a D segment. In humans, there are two different possible light chain proteins, termed kappa and lambda. Assume that there are 35 V segments and 5 J segments in the human kappa light chain region, and there are 30 V segments and 4 J segments in the human lambda light chain region. How many possible light chain genes can be created from these different segments, simply due to combinatorial diversity
Answer:
295
Explanation:
Antibodies (also known as immunoglobulins) are immune system-related proteins that circulate in the bloodstream in order to recognize pathogenic harmful substances (antigens) and neutralize them. An antibody consists of two immunoglobulin heavy chains and two immunoglobulin light chains. There are two types of immunoglobulin light chains: 1-the kappa (κ) light chain, which is encoded by the immunoglobulin κ locus; and 2-the lambda (λ) light chain, which is encoded by the immunoglobulin λ locus. The immunoglobulin light chain is a multidomain protein composed of two domains: 1- the N-terminal variable (V) domain and 2-the C-terminal constant (C) domain. V(D)J recombination is a type of somatic rearrangement process by which T and B cells can assemble different gene segments, which are referred to as variable (V), diversity (D) and joining (J) gene segments. In the question above the number of possible genomic recombination events between immunoglobulin gene segments can be calculated as >> (5 x 35) + (4 x 30) = 295.

The change that occurs at point C could be caused by Multiple choice question. A) increased predation by wolves. B) a wet year with increased vegetative growth. C) increased competition from moose herds. D) a dry year with decreased vegetative growth.
Answer:
The answer is "Option B"
Explanation:
A wet season with increased plant growth is indicated by the fact that the population of Elks from beginning point C attained maximum population size (K100) and remained stable until point D. That's why the difference at point C could be due to the a wet year still higher plant growth.
The pre-australopith fossils are especially significant because they challenge some of the long-standing explanations of our evolutionary history. Describe two reasons the pre-australopiths force us to rethink the savanna hypothesis in particular. (Hint: Think about the anatomical traits of the pre-australopiths and the environmental and temporal context in which they lived.)
Two important reasons are listed here:
- Pre-australopithecines show evidence of bipedalism but they lived in forested areas
- Ardipithecus ramidus is a human ancestor that lived in a wooded environment approximately 4.2 to 4.5 million years ago
The savanna hypothesis states that early hominid traits were selected in response to increased aridity conditions and the emergence of savanna landscapes (i.e., open grasslands), as forests receded. This hypothesis enables us to understand better the evolution of bipedalism.
Pre-Australopithecines represent the oldest hominids that date from at least 7 to 4.4 million years ago (mya), depending on the species. Pre-australopithecines show evidence of bipedalism (and/or dentition similar to the later hominins who exhibit bipedalism), but it has been shown that they lived in forested areas. Therefore, this observation contradicts the savanna hypothesis which states that bipedalism evolved as an adaptation to the savanna.
Ardipithecus ramidus is a human ancestor dating to between 4.5 and 4.2 mya. The Ardipithecus ramidus fossils were discovered in Ethiopia alongside faunal remains, thereby indicating they lived in a wooded environment. In consequence, Ardipithecus ramidus fossils contradict the open savanna explanation for the origin of bipedalism.

In a certain breed of dog, the alleles B and b determine black and brown coats respectively. However, the allele Q of a gene on a separate chromosome is epistatic to the B and b color alleles resulting in a gray coat (q has no effect on color). If animals of genotype B/b ; Q/q are intercrossed, what phenotypic ratio is expected in the progeny
Answer:
12 gray , 3 black, 1 brown
Explanation:
If Q allele of a gene on a separate chromosomes is epistatic to the B (black) and b (brown) color alleles, in cross between two animals with genotypes BbQq produces 12 gray coat color, 3 black coat color and 1 brown coat color animals.
BbQq x BbQq
Gray coat Gray coat
BQ Bq bQ bq
BQ BBQQ(gray) BBQq(gray) BbQQ(gray) BbQq(gray)
Bq BBQq(gray) BBqq(Black) BbQq(gray) Bbqq(Black)
bQ BbQQ(gray) BbQq(gray) bbQQ(gray) bbQq(gray)
