Answer:

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.

What can result from weakening of digestive smooth muscle with age?
Alex17521 [72]

Answer:

Weakening of digestive smooth muscle with age can cause constipation.

Explanation:

Smooth muscles in the digestive system have the role to move food down the tract via radially symmetrical contractions (peristalsis). With age, the function of smooth muscles reduces, causing the food to move more slowly through the alimentary canal (digestive tract). As a consequence, water gets absorbed from food waste, which can cause constipation.

Identify whether or not the different agents of evolutionary change could affect allele frequencies in a population?
igomit [66]

Yes, the different frequencies of evolutionary change could affect allele frequency in a population.

<h3>What are the agents of evolutionary change? </h3>

All populations are usual in a constant state of evolution. This means that all the species are continuously changing their genetic makeup over different generations. These changes can be subtle or they can be spontaneous.

If a population is not evolving, it is said to be in Hardy - Weinberg state. In this state, the allele frequency and the genetic makeup of the population will remain the same across generations.

The agents of evolutionary change defy the Hardy - Weinberg state. These are mutation, gene flow, non-random mating, natural selection and genetic drift.
