The wing of a penguin is ________ the arm of a human.

Biology
1 answer:
Leokris [45]3 years ago
8 0

The wing of a penguin is homologous to the arm of a human.

Homologous organs refer to organs of different organisms that are structurally similar but functionally different.

The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.

Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.

What conclusions can we draw from the lab about photosynthesis and cellular
GuDViN [60]

Answer:

Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration forever unless something interrupts.

Explanation:

Photosynthesis and cellular respiration are two distinct and opposite metabolical processes undergone by living cells. They are opposite processes because one utilizes the products of the other as reactants.

Photosynthesis is a unique process to autotrophic organisms like plants. It is the process whereby plants synthesize their food in form of organic molecules (glucose) by combining Carbondioxide (CO2) and water (H2O) in the presence of sunlight.

The overall equation of photosynthesis is as follows:

6CO2 + 6H2O ------> C6H12O6+ 6O2

On the other hand, cellular respiration is the process whereby living cells obtain energy (ATP) by breaking down food molecules (glucose) using oxygen to produce carbondioxide (CO2) and water as products. The overall equation is:

C6H12O6 + 602 -----> 6CO2 + 6H2O

Based on the lab experiments, it can be concluded that Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration because photosynthesis recycles/reuses the products of cellular respiration, which are C02 and H2O while cellular respiration recycles/reuses the products of photosynthesis, which are C6H12O6 and O2. This process occurs naturally in the environment and will continue to do so unless something interupts.

Option B is incorrect because light energy from the sun powers photosynthesis while option C is incorrect because photosynthesis transforms light energy to chemical energy while cellular respiration transforms chemical energy to thermal energy.

A client whose parkinson's disease is being treated with tolcapone should concurrently take what drug?
steposvetlana [31]

Answer:

The correct answer would be levodopa/carbidopa.

Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.

These drugs are used to treat the symptoms of Parkinson's disease.

Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).

In the brain, levodopa is converted into dopamine which helps in controlling the movement.

Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
