Answer: A. An animal may be a regulator for one environmental variable but a conformer for another.

Explanation: 'An animal may be a regulator for one environmental variable but a conformer for another' is the correct statement when describing feedback control in animals. Animals are constantly adjusting the internal and external behavior or processes in other to attain a steady state or equilibrium through a process called homeostasis. The adjustments are required to maintain a set range in body glucose, calcium, temperature and so on to aid efficient function of the body system.

For instance temperature, cold-blooded animals or ectotherms depends on external heat sources, therefore conform to the environmental temperature While endotherms possess the ability to maintain a constant steady temperature independent of the environment.

If all living things are related then where did all their differences come from?
stiks02 [169]

Answer:

<em>Hox </em>Gene

Explanation:

First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.

But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.

For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.

Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.

What would happen on a hot day if your brain did not receive input that your body was starting to heat up
Karolina [17]

Answer:

The body will overheat

Explanation:

If the brain of an individual does not receive input that the body was starting to heat up on a hot day, <u>the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating. </u>

Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding.<em> Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.</em>
