Answer:

A. Adaptation

Explanation:

Adaptation refers to the evolutionary process in which organisms undergo mutation or genetic change over many generations, which makes the organisms become better suited to multiply and survive in its habitat. The genetic mutation of Daphnia which makes them develop a trait that makes subsequent generations to prefer warmer environments is an example of adaptation of the organism to his environment.

The human infant spends about half of its sleep time in rem. What is the understanding of why this is the case?
Molodets [167]

This occurs because REM sleep may provide at least part of the stimulation necessary to correctly develope the immature brain of infants.

REM sleep provides the electrical activity necessary to establish neural connections that include the  development of synapses in the brain. These neurological process enables development of sensory, motor, learning and memory system.

arlik [135]

Answer:

B) nuclei of gland cells.

Explanation:

DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.

However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.

Which of the following statements about fluid movement is NOT correct?
allochka39001 [22]

Answer:

b. Exchange between the plasma and the intracellular fluid occurs across the cell membrane.

Explanation:

The body fluid can be categorized as extracellular and intracellular fluid. The fluid within cells is called intracellular fluid and the body fluid outside body cells makes the extracellular fluid. The interstitial fluid is the extracellular fluid that is present in the narrow spaces between cells of tissues.

On the other hand, the extracellular fluid present within blood vessels is termed blood plasma. Therefore, plasma and intracellular fluid can exchange material via interstitial fluid only, not directly via the cell membrane. The exchange between interstitial fluid and intracellular fluid occurs across the cell membrane.
