2. Why do scientists often use thermoacidophile group of archaebacteria for research?
Archaebacteria have some unique characteristics.
Although members of kingdom Archaebacteria share many characteristics with members of kingdom Eubacteria, some of their characteristics are unique.
One such characteristic is the ability of archaea to live in extreme conditions.
What is Thermoacidophile archaebacteria?Thermoacidophile archaebacteria are a type of archaea that thrive in extremely hot and strong acidic (with low PH) environments. Thermoacidophile archaebacteria can be found in harsh environments such as in geothermal area, in the deep ocean vents and hot springs. Most of the
Thermoacidophile archaebacteria are chemotrophs (converts chemicals to food). They use sulfur as their energy source. They absorb the sulfur gas that is being released in their environment and reduce it to hydrogen sulphide, fixing it into an energy source.
Thus, this could be the answer.

Explanation:
Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If all of these genes are on the same chromosome, and there is no recombination, how many different genotypes will occur in the F2
Answer:
2 genotypes: AABBCCDDEE; aabbccddee
Explanation:
The law of segregation (also called Mendel's First Law) describes how genes on different chromosomes segregate into gametes independently of each other. Moreover, recombination (also known as crossing over) is the interchange of genetic material between non-sister chromatids during meiosis. In this case, the five genes are on the same chromosome (i.e., they are linked together and do not segregate) and there is no recombination, thereby they are inherited as a haplotype block to the next generation:
- Genotypes parental (P) lines: AABBCCDDEE; aabbccddee
- Cross P1: ABCDE X abcde
- Genotype F1: AaBbCcDdEe (100%)
- Gametes F1: ABCDE; abcde
- Genotypes F2: AABBCCDDEE; aabbccddee (ratio 1:1)
Explain in detail what caused the population of peppered moths to change from mostly light-colored variations to mostly dark-colored variations in the 1800s. Explain how the peppered moth mutation is an example of natural selection. Explain what would happen to the populations of both variations of peppered moth once the pollution disappeared. Determine which variation of the peppered moth would be more successful in your neighborhood, and explain in detail your reasoning supporting your conclusion. Predict what may happen to the population of peppered moths if they were relocated to a lush, green rainforest ecosystem. How would this impact natural selection and their struggle to survive?
Answer:
Natural selection caused the population of peppered moths to change from mostly light-colored variations to mostly dark-colored variations in the 1800s. Pepper colored moths camouflaged among trees but after industrial revolution the couldn't because of soot, which camouflaged black moths; hence, they were preyed upon more.
Identify the energy carrier molecule ATP and its importance
A research group discovers that a reagent can be used to form covalent cross-links between various types of atoms in both small molecules and proteins. They add the reagent to a mixture of 14C-lactose and a protein that is thought to have a specific binding site for lactose. What should they do next to draw a conclusion about whether the protein specifically binds lactose
Answer and Explanation:
Ideally, researchers would measure the stoichiometry of the mixture labeled with 14C-lactose and a protein. By measuring this stoichiometry, researchers should be able to find a concentration between lactose and protein of 1:1. This concentration is able to determine that the protein has specifically bound to lactose.
In summary, to determine whether the protein binds lactose, researchers need to calculate whether the concentration of these two elements within the mixture is 1:1.
How does disease and parasitism cause extinction?
Explanation:
Invading infectious diseases can, in theory, lead to the extinction of host populations, particularly if reservoir species are present or if disease transmission is frequency-dependent.
Answer:
Abstract. Infectious disease, particularly severe infectious disease, is widely recognized as a cause of biological population fluctuation or decrease. However, it is not usually thought to be a major factor in triggering species extinction or endangerment.

A student is conducting their science experiment on the effect of caffeine on dogs. He has 3 groups of test subjects. The 1st group of dogs receives plain water. The 2nd group of dogs receives 10 mg of caffeine each, and the 3rd group receives 50 mg of caffeine each. He will measure their activity levels by recording how long each dog runs without stopping, after giving them the pills. What is the dependent variable in this experiment?
Answer:
The amount of activity
Explanation:
In an experiment, the independent variable is the variable that the scientist/investigator purposely changes or manipulates, which isn't changed by other variables in the experiment (in this case, the amount of caffeine). On the other hand, the dependent variable is the variable that is being measured or tested during the experimental procedure (this variable is 'dependent' on the independent variable). Finally, the control group is defined as the group of individuals/subjects who do not receive the experimental treatment (in this case, the dogs that receive water).

CRISPR-Cas9 is a genome editing tool that is creating a buzz in the science world. It is faster, cheaper and more accurate than previous techniques of editing DNA and has a wide range of potential applications.
Explanation:
HOW CRISPR IS DIFFERENT FROM OTHER TECHNOLOGIES
CRISPR-Cpf1 differs in several important ways from the previously described Cas9, with significant implications for research and therapeutics. ... The Cpf1 system is simpler in that it requires only a single RNA. The Cpf1 enzyme is also smaller than the standard SpCas9, making it easier to deliver into cells and tissues.
Once the neural plate edges have fused to become a neural tube, the tissues that were at the edges of the plate now form the __________ region the neural tube. Fill in the blank.
Answer: Dorsal.
Explanation:
The neural plate is a region of the dorsal ectoderm that develops into the neural ectoderm. It is a flat structure, with columnar appearing cells, and the formation of the neural ectoderm is the first step in the neurulation process. This region is generated from the thickened mid-dorsal surface opposite the primitive line of the ectoderm. From this epithelial zone the various types of neuronal and glia cells belonging to the nervous system are derived. For the neural plate to be built, it is necessary that the epiblast cells converge towards the midline of the embryonic disc forming a groove of the primitive line, delimiting a longitudinal axis of bilateral symmetry around which the embryonic structures and their organs will be aligned. From this moment on, the embryo will have a rostral (cephalic) and caudal (tail) region as well as a left and right side and a dorsal (back) and ventral (front) surface. From the folding of the neural plate or neurulation, the neural tube and the development of the entire nervous system will be formed.
The neural tube is tubular structure that undergoes modifications and will give rise to a central nervous system structure (encephalon and spinal cord). The neurulation process begins by means of signals sent by the dorsal mesoderm and pharyngeal endoderm to the ectodermal cells located above these germ layers. These signals cause this area of the ectoderm to elongate into a columnar plate of cells. The elongation allows the differentiation of the cells of the future neural plate, with respect to the pre-epidermal cells surrounding the area.
So, the neural tube is formed by invagination from the dorsal region of the ectoderm (neural plate) induced by the notochord while it is forming. This occurs at the beginning of the third week of conception by a process called neurulation.
Which of the following is an example of an enzymatic cycle?
Answer:
Catabolism
Explanation:
The process of catabolism degrades the bacterial and fungal enzymes into simple inorganic molecules.
A substance, without being a reactant, which speeds up a chemical process is referred to as a catalyst. Enzymes are known as catalysts for biological reactions in living organisms. Although ribonucleic acid (RNA) molecules behave as enzymes, they are usual proteins. Enzymes.
Enzymes carry out the essential role of reducing the activated energy of a reaction — that is, the amount of energy needed to start the process. Enzymes work by attaching and retaining reactant molecules so that the chemical bonding and bonding activities are carried out more easily.
plz give a correct answer for the question how do canine and molar differ
Answer:
Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food
Molars are the flat teeth at the rear of the mouth. Each molar typically has four or five cusps. They are used exclusively for crushing and grinding. Wisdom teeth are also called third molars. They erupt from the age of 18 onwards but are often surgically removed.Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.

The complete oxidation of one glucose molecule yields 30 or more ATP . Glucose catabolism includes glycolysis, pyruvate oxidation, and the citric acid cycle. The total yield of ATP includes ATP , GTP , and reduced cofactors that yield ATP from the electron transport chain and oxidative phosphorylation. Which processes yield the most ATP
Answer:
Electron transport chain.
Explanation:
Electron transport chain is the process which yield the most number of ATP as compared to all three major phases of cellular respiration. Glycolysis produces only 2 ATP from the breakdown of molecule of glucose. In the Krebs cycle, one GTP which is an ATP equivalent is produced from the breakdown of one glucose molecule while on the other hand, 32 ATP molecules are produced from the breakdown of one glucose molecule.

By the early 1980s, the population of Florida panthers had dwindled to fewer than 30. Furthermore, within this population was a high frequency of detrimental traits, including low sperm count and undescended testicles in males, and kinked tails in both sexes. The future for this iconic population was bleak at best. Provide an explanation for the observed detrimental traits. Provide a possible solution that would both increase the likelihood that the population would survive and preserve the genetic identity of this unique population.
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.

Which of the following is not a difference between photosynthesis and
cellular respiration?
A. Where they occur in cells
B. Being part of the carbon cycle
C. The products of the processes
D. The materials needed for the processes
Answer:
[tex]\boxed {\boxed {\sf B. \ Being \ part \ of \ the \ carbon \ cycle}}[/tex]
Explanation:
Photosynthesis and cellular respiration are both important processes to utilize energy and maintain life in an organism. There are many differences between the two, but we are asked to identify the answer that is not a difference.
A. Where they occur in cells
Photosynthesis occurs in chloroplasts in plants, algae, and some bacteria. Cellular respiration occurs in mitochondria in all organisms. This is a difference.
B. Part of the carbon cycle
The carbon cycle describes the exchange and movement of carbon throughout the Earth, atmosphere, and biosphere. Photosynthesis uses carbon dioxide and cellular respiration produces it, so they are both part of the carbon cycle. This is not a difference. This seems to be correct, but let's check the other choices.
C. The products of the processes
Photosynthesis produces oxygen and glucose, while cellular respiration makes carbon dioxide, water, and energy or ATP.
D. The materials needed for the processes
Photosynthesis needs carbon dioxide, water, and energy from the sun, while cellular respiration needs oxygen and glucose.
Both photosynthesis and cellular respiration are part of the carbon cycle, so the choice that is not a difference is Choice B.
