Answer:
a. Heart
b. pulmonary artery
c. lungs
d. pulmonary vein
e. heart
f. aorta
g. arteries
h. big toe.
Explanation:
First I ( drop of blood) will go from the heart to the lungs through pulmonary artery in order to purification from carbondioxide and loaded oxygen. After that, I return to the heart through pulmonary vein and the heart pump this blood to the aorta which is a big blood vessel that branched into small arteries that reaches to every cell of the body and through these arteries I reach the big toe of the foot.
where does the energy for active transport come from
Answer:
Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. Energy for the process is acquired from the breakdown of glucose using oxygen in aerobic respiration. ATP is produced during respiration and releases the energy for active transport.

What are some Characteristics of a ladybug after metamorphosis
Answer:
Ladybug physical characteristics
The ladybug has an oval-shaped body, six legs, two antennae, a head with two eyes, a thorax that is called a pronotum, and an abdomen (the part of the body that is covered by the elytra). When the pupa hatches as a new adult ladybug, it doesn't have any spots yet and its elytra are wet, soft, and pale colored.

Which sequence correctly indicates the branching pattern of the human respiratory system?
A) trachea bronchi bronchioles alveoli
B) trachea bronchioles bronchi alveoli
C) alveoli trachea bronchioles bronchi
D) alveoli bronchioles trachea bronchi
Answer:
A
Explanation:
The system including tissues and organs needed for breathing and exchanging gases is called the respiratory system. It is essential for providing fresh air and eliminating the waste air from the body.
The branching pattern of the human respiratory system includes option A) trachea bronchi bronchioles and alveoli.
The Respiratory system can be explained as:The respiratory system includes the major organ lungs which along with some other tissues makes up the whole system. The trachea gets diverged into two branches named bronchi which further splits into lungs called bronchioles.The bronchioles spread throughout the lungs and have a sac-like small structure on its end called alveoli where the exchange of gases takes place.Therefore, option A is the correct sequence of respiratory branching.

Explain how DNA results in the expression of a gene using the following words: DNA, mRNA, tRNA, gene, transcription, and translation
Explanation:
in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.

how does parasitism differ from other symbiotic relationships?? (please help of you know it )
Answer:
Symbiosis is when one creature benefits while the other is unaffected. Parasitism is when one creature benefits while the other is harmed.
Explanation:
Think of parasites. They feed off of other creatures and harm them in the process. Symbiosis is similar, but neither creature is harmed.
A tall pea plant with red flowers has the genotype TtRr. This plant is crossed with another tall pea plant with white flowers, having the genotype Ttrr. What is the probability of getting dwarf plants with red flowers in the F1 progeny
Answer:
1/8 or 12.5%
Explanation:
This question involves two genes coding for height and flower color in pea plant. The alleles for tallness (T) and red flowers (R) are dominant over the alleles of short (t) and white flowers (r).
According to this question, a tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr). The following gametes is produced by each parent:
TtRr - TR, Tr, tR and tr
Ttrr - Tr, Tr, tr and TR
Using these gametes in a punnet square (see attached image), the following proportion of F1 offsprings will be produced as follows:
Tall, Red (T_R_) = 6
Tall, white (T_rr) = 6
Dwarf, red (ttR_) = 2
Dwarf, white (ttrr) = 2
The probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

12.5

Answer:
eukaryotic chromosomes
Explanation:
Prokaryotic chromosomes have a single source of replication whereas numerous sources of eukaryotic chromosomes. Since eukaryotic chromosomes are much larger, many outlets are required for the whole chromosome to be repeated within a limited period of time.
A replication root is a segment of DNA in which a gene, plasmid or virus is repeated.
Name two types of pathways that help a body maintain homeostasis, and an example of each.
Answer:
Explanation:
The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water.
Answer:
The receptor and afferent pathway are pathways that help the body stay n homeostasis. An example of the receptor is like temperatures in your skin. An example of Afferent pathways are sensory neutrons.

In a cross Bb x Bb (B = Blue petals and b = pink petals), how many offspring will have the genotype Bb?
Answer:
2 offspring will have the genotype Bb.
Explanation:
Crossing the genotypes Bb and Bb results in 2, or 50% of the offspring having the genotype Bb. In the top right box, the B on the top and the B on the side make the BB genotype. In the top left box, B and b make the first Bb genotype. The lower right box crosses B and b to make the second Bb genotype. The last box in the bottom right crosses b and b, resulting in the genotype bb. So, after crossing the genotypes written on the top and side of the punnet square, 2 of the offspring will have the Bb genotype. (I got this by combining the letters outside the punnet square in the box where the row and column meet) .
