Why do structural similarities between living things point to common ancestry?

Biology
1 answer:
adoni [48]3 years ago
5 0

Explanation:

Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies. Both provide evidence for evolution. ... The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.

What is the main difference between weather and climate?
8_murik_8 [283]

Answer: Option B) The length of time over which the conditions are measured

Explanation:

Weather is the atmospheric condition of a given area over a short period of time, usually days to several months

Climate, on the other hand, is the atmospheric condition of a given area over a long period of time, usually over 2 years.

Thus, weather and climate differ based on the length of time over which the conditions are measured.

PLS HELP!!! What best describes the relationship between
rusak2 [61]

Answer:

Interspecific competition

Explanation:

Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.

The graph given shows the growth of the relative population size of two different species grown together.

It shows that P. aurelia, with time, outcompetes P. coudatum.

This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.

P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.

Interspecific competition beats describes the relationship between the two species in graph B.

A man who smokes heavily has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, ma
Naya [18.7K]

Answer:

The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.

Explanation:

  • The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
  • The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
  • In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
  • The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
  • Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
  • However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
  • Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.
