The upper forelimbs of humans and bats have fairly similar skeletal structures, whereas the corresponding bones in whales have v

ery different shapes and proportions. However, genetic data suggest that all three kinds of organisms diverged from a common same time. Which of the following is the ancestor at about the most likely explanation for these data?
A. Forelimb evolution was adaptive in people and bats, but not in whales.
B. Whales are not properly classified as mammals.
C. Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy
D. Genes mutate faster in whales than in humans or bats.
E. Humans and bats evolved by natural selection, and whales evolved by Lamarckian mechanisms.

<h2>Option C is correct</h2>

Explanation:

Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy

  • Natural selection is the concept of evolution where organisms with favorable traits are selected(by nature) and reproduced and this process allows the organisms to adapt to the changing environmental conditions
  • The upper forelimbs of humans and bats have fairly similar skeletal structures which means that they might share a common ancestor in skeletal structure but are functionally different which means they share a homology with each other
  • The evolution of limbs of whales is also a part of forelimb adaptive evolution
  • Gene mutation rates of higher animals are pretty much similar
  • Whales are proper mammals and form a connecting link between fish and mammals

Which organ is responsible for storing urine?
lara [203]
The answer is bladder
The bladder stores urine and when the brain signals to release (when we have to go pee) it releases the urine through the urethra. The answer is not kidney because it doesn’t STORE the urine it filters waste and toxins in the body into the urine to be released from the body, the actual bladder itself is the organ that stores the urine in the body.

emmasim [6.3K]
<span>Diet drugs such as lorcaserin and phentermine-topiramate help people in losing weight by reducing food intake. These drugs are affecting the central nervous system, which act as an appetite suppressant where a person will not feel hungry or has lesser urge in eating does reducing his/her food intake. Weight loss will be much effective if these drugs will be adjunct with exercise and reducing caloric intake.</span>

Which phrase describes a density-independent limiting factor that can affect
Alenkasestr [34]

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

<h3>What is a density-independent limiting factor?</h3>

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.

Which structure is at work when the body deals with reflex actions?
Ne4ueva [31]

Answer:

spinal cord

Explanation:

Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.

Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.

Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.  

Hence, the correct option is spinal cord.
