Answer:
Explanation:
The color of our hair, skin, and eyes is determined by the same thing: the amount of pigment they have. The pigment that causes dark hair, skin, and eyes is called melanin. Melanin is made in special cells in the body called melanocytes.
A female mosquito can produce 50-500 offspring in a two-week period of time. This rapid reproduction can also result in fast
evolution for this small insect species. For example, pesticide resistance occurs rapidly in insects, including mosquitos. Insecticides
that were once effective at eradicating mosquito populations are no longer effective. Which component of natural selection is
Likely playing a role in this rapid evolution for mosquitos?
A)
Mosquitoes pass only advantageous traits on to their offspring during
reproduction. This ensures increased survival and reproduction.
B)
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
Mosquitoes that learn to avoid pesticide exposure can pass that
information on to offspring. This increases the survival of those offspring
as well.
D)
Mosquitos have the ability to detect areas with high pesticide loads and
can avoid those areas. This allows mosquitos to survive and reproduce with
more success.
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
What are mosquitoes?Mosquitoes are ectoparasites, which live on the blood of different animals.
They suck blood from the skin of animals and leave red spots, which are itchy.
Mosquitoes lay their eggs in water and live in dirty, moist, dark places.
They are also responsible to cause malaria in humans.
Thus, the correct option is B.

Which effect does deforestation have on the carbon cycle?
Answer:
Deforestation facilitates one part of the carbon cycle, increasing the CO2 in the atmosphere. It also prevents forests from absorbing any further carbon by destroying the trees. It, therefore, inhibits this aspect of the cycle and leads to increased levels of this greenhouse gas in the atmosphere.
Explanation:
Another plant is said to be heterozygous for flower color. What does this mean?
Answer:
Depending on how the gene works, it might result in an orange flower or in a flower that’s just yellow or in one that’s just red—but with the potential to have offspring of a different color. Such a flower would be said to be heterozygous for flower color, because it’s got a copy of one yellow allele and one red allele.
Explanation:
If green is dominant to yellow what is the genotype
Answer:
The dominant seed color is yellow; therefore, the parental genotypes were YY for the plants with yellow seeds and yy for the plants with green seeds.

In systemic circulation, a drop of blood that is [ Select ] ["poor in oxygen", "rich in oxygen"] in the [ Select ] ["right atrium", "left atrium", "right ventricle"] will first travel through the [ Select ] ["pulmonary semilunar valve", "aortic semilunar valve", "tricuspid valve", "bicuspid valve"] to reach the left ventricle. From there it will be pumped through the [ Select ] ["bicuspid valve", "pulmonary semilunar valve", "aortic semilunar valve", "tricuspid valve"] to reach the [ Select ] ["aorta", "pulmonary artery", "pulmonary trunk", "superior vena cava"] , which will branch into smaller arteries and arterioles. The blood leaving the arterioles will enter the capillaries surrounding the systemic tissues. The blood exiting the capillaries is [ Select ] ["rich in oxygen", "poor in oxygen"] and will first travel in venules, which will fuse into bigger veins. Eventually the blood will enter into the [ Select ] ["right ventricle", "left atrium", "right atrium", "left ventricle"] via either [ Select ] ["aorta or pulmonary artery", "pulmonary artery or pulmonary vein", "superior vena cava or inferior vena cava"]
In systemic circulation, a drop of blood that is rich in oxygen in the left atrium will first travel through the bicuspid valve to reach the left ventricle. From there it will be pumped through the aortic semilunar valve to reach the aorta which will branch into arterioles.
The blood exiting the capillaries is poor in oxygen and will first travel in venules, which will fuse into bigger veins. Eventually the blood will enter into the right ventricule via either superior vena cava or inferior vena cava.
What is Systemic circulation?This involves blood vessels supplying oxygenated blood to and returning deoxygenated blood from the tissues of the body.

Which of the following results when homologous chromosomes cross over in meiosis?
Two sister chromatids get tangled, resulting in one re-sequencing its DNA.
DNA repair machinery alters maternal alleles so they match paternal ones
Two sister chromatids exchange identical pieces of DNA.
Corresponding segments of non-sister chromatids are exchanged.
When homologous chromosomes cross over in the process of meiosis, the corresponding segments of the non-sister chromatids are exchanged. Thus, the correct option is D.
What is Crossing over?
Meiosis is the process of cell division in which the chromosomal content of the cell reduces to half. This division is also known as reductional division. Meiosis is divided into two parts: Meiosis I and Meiosis II.
Meiosis I is divided into four phases which are Prophase I, Metaphase I, Anaphase I, and Telophase I. Prophase I is further divided into five stages which are Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis. Crossing over of chromosomes takes place during pachytene stage.
Crossing over or the chromosomal crossover is the exchange of the genetic material during the process of sexual reproduction between the two homologous chromosomes' non-sister chromatids which results into the formation of recombinant chromosomes.
Therefore, the correct option is D.

Explain why cellular respiration releases energy as an overall chemical reaction
Answer:
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP
In other words:
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
