Answer:
down
Explanation:
because gravity come from the center of the earth the gravitational pull, pulls us down.
We know, DNA is the main molecule by which scientists can learn about evolution by comparing the DNA structure between two different organisms.
But, in addition to DNA (which is most helpful & important) still, there are 3 molecules that can help us, They are:
1) RNA : - It is found in cytoplasm, as DNA transfers it's codes into RNA during Central dogma, it can help us in evolution studies.
2) Proteins: - Another helpful feature, into which RNA transforms in Central Dogma.
3) Pseudogenes: - It is also known as "Non-coding DNA" It is extra <span>DNA in a genome that do not get transcribed into RNA to synthesize proteins. They can also help us in Evolutionary studies.

Answer:
The genotype of male with red-green color blindness is XY, X chromosome possessing recessive allele of gene responsible for differentiating red-green color.
Explanation:
Color blindness is sex-linked trait and its inheritance follows criss-cross pattern. Dominant gene of allelomorpihc pair enables a person to differentiate between red and green color.
The genotype of male and female are different for the pair of sex chromosomes. Male is hetero-zygous (XY) and female is homo-zygous (XX). The gene controlling this trait is present on X chromosome.

Answer:
Option (B) is the correct answer of the following question.
Explanation:
Collagens are a family of enzymes that perpetuate and protect many of the body's tissues, with the exception of connective tissue, femur, fibula, pigmentation, and the caucasian eye (optic disc). It would be the best choice on which to base the phylogeny.
- The first and most concentrated substance in the body is the collagen genes.
- It is a large, indigestible cellular muscle which maintains organisms and gives internal cells a texture.
- Collagen is also an essential part of the crisscrossing membrane neurons.
Other options are incorrect because they are not related to the given scenario.
