Define homologous structures and explain how these structures support evidence of common ancestry

Biology
1 answer:
Andrews [41]3 years ago
5 0
<span>Homologous structures are framework where the parts of the body is similar in structure to different species of common ancestry. The way structures develop in embryos and the pattern in which they appeared over evolutionary history. In addition, the evidence of this common ancestry can be seen in the structure and development of these homologous structures, even if the existence of these structures adapted to different function as the result from a collective ancestry. </span>

Which type of mutation is seen in a sperm cell but not in a skin cell?
katovenus [111]

Answer:

An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.

Explanation:

when a skin stem cell harbors a cancer-driving mutation, it becomes more likely to generate two specialized skin cells when it divides. Over time, the mutated skin stem cell fails to renew itself and turns into cells that eventually slough off, allowing the skin to expel mutated cells as needed.

Errors in DNA copying during cell division and development can cause new mutations — called de novo mutations — at any time from the moment of conception. Mutations that occur in the germ line — the cells that develop into sperm or eggs — can be passed on to the next generation and, perhaps, cause disease in children.

Harlamova29_29 [7]
A) The child will likely have Gaucher Disease if she inherited RECESSIVE alleles from each parent.

D is ruled out because if the child only received one recessive allele but her other allele is dominant, then the most she could be is a carrier. Dominant over recessive.

C is wrong because the question states that the disease is a recessive pattern, while C is stating that the child would only have it if it inherited dominant alleles.

B is wrong. Like D, it’s dominant over recessive and the most the child could be is a carrier.

Therefore, I believe the answer is A, the first one.

Which statements describe S waves? Check all that apply.
arlik [135]

They arrive after P waves.

They travel through solids.

S waves (Secondary or Shear waves) are known to be type of waves that travel through the solid and also travel slower when compared with P-waves. S-waves are refers to as shear waves because they don’t change the volume of the materials through which they travel or propagate, they shear it. Furthermore, S-waves are transverse waves because they vibrate ground in transverse direction or perpendicular to the direction in which the waves travels.
