Answer:
Organisms maintain dynamic homeostasis through behavioral and physiological mechanisms. Which of the following statements is an accurate explanation of a negative feedback mechanism used by animals to regulate body temperature? C) A ground squirrel's hypothalamus detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production
Explanation:
The temperature-regulating center of vertebrate animals is located in the hypothalamus. A ground squirrel's in there detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production. Maintenance of homeostasis usually involves negative feedback loops.
Answer:
Normal human cells have 46 chromosomes while gametes have 23 chromosomes.
Answer: D. economic incentives
Explanation:
Economic incentive refers to the kind of motivation strategy in which the person is provided with financial assistance and fulfill other kind of preferences according to needs, desire and wants of the person in return receiving the required task to be done or for achieving a social goal.
The given situation is an example of economic incentive this is because of the fact that mothers are provided with the paid family leave from work this is helpful in increasing the birth rate of woman. This is in effort for preventing a declining population.
Evidence validates conclusion
Answer:
(Fill in the blank) When comparing DNA and structural characteristics between plant species, the similarities that appear can indicate a genetic adaptation to a particular environment, between them.
Explanation:
The evolution of the spice indicates that there were changes in the environment where these plants were able to adapt genetically, and not only that but they transmitted it in their generations, that is why many manifest the same genetic code, if this gene was inherited among them it means that the species EVOLVED.
Otherwise, those genes that generate benefits for the plants but are not transmitted in the parent plants will not be considered as an evolutionary change of the species but individual of the plant.
The genetic changes produced by modifications in the environment translate into phenotypic changes, thus generating a more suitable species with a greater chance of survival.
