Need help with this evolution chart some I've filled in yet I'm not sure if they are correct.Plz help anybody

Svetllana [295]

Answer:

This is correct. The remaining portion:

Sympatric species that form interrelationships undergo coevolution.

Allopatric species in different environments can undergo convergent evolution.

Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.

Explanation:

On the basis of geographical distance, speciation is of two major types:

Sympatric
Allopatric

Sympatric Speciation:

Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.

Allopatric Speciation:

It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.

Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.

Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.

Nonamiya [84]

Answer:

tt

Explanation:

Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.

tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.

So it would make sense that tt is the choice.

Read the following passage and construct a flow chart by matching the following events with their proper sequence. Physical exer

blsea [12.9K]

Answer:

Person starts to exercise.

Skeletal muscle oxygen demand increase

Skeletal muscle metabolism increases

.Blood delivery to the skeletal muscle increases is order to provide more oxygen

Oxygen sensors cause local blood cell vessels to dilate

.

This steps briefly describe the physiology of exercise.

At the onset of exercise, skeletal muscles cells were sustained with available oxygen from the Myoglobin. Myoglobin is oxygen binding and storage protein found in cardiac and skeletal muscles cells. it has high storing capacity for oxygen.

However as the exercise becomes intense ATPs supply drops, oxygen demand increases,cellular metabolisms demand also increase to supply glucose and ATP to the cells.

The liver mediates Gluconeogenesis. Fatty acid is broken down to glucose for cellular respiration with' ketone bodies build up..Exercise also stimulates the breakdown of muscle glycogen to glucose, Therefore, cellular respiration takes place to break down the glucose to C02, H20 and energy with rise in temperature.

However, oxygen concentration is low, therefore muscles cells undergo anaerobic respiration with lactic acid pathway. Lactic acid build up in muscles cells.The muscles cells under go oxygen debt to break down lactic acid to glucose in muscle.

Therefore to adjust the mechanism oxygen homeostatic sensors increases hyperventilation to increase oxygen intake through the lungs, and vasodilation. so that maximum volume of blood containing oxygen is transported to muscles cells; to sustain the intense activity
