Under certain external conditions, a person will perspire a great deal. For which internal condition does this response
primarily provide homeostasis?
water balance
electrolyte balance
temperature balance
energy balance
Answers
Answer:
Perspiration provides homeostasis to the internal condition of temperature balance.
Explanation:
Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.
The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.
The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.
The other options are not correct because:
Water and electrolyte balance is done at the renal level. The energy balance depends on the food intake and the amount of energy used.Answer:

Where does the water enter the plant in photosynthesis?
Answers
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

If you poured the fluids below into a container, which would sink to the bottom?
-water with a density of 1.0 g/cm3
-vegetable oil with a density of 0.91 g/cm3
-honey with a density of 1.36 g/cm3
-air with a density of 0.00013 g/cm3
Answers
Answer:
Honey > Water > oil > air
Explanation:
Heavy density will sink and less heavy density will float
So,
Density of honey is highest so, honey will sink
than,
Density of water is higher so, vegetable oil will float
Density of oil is higher so, air will float
Honey > Water > oil > air

This organelle modifies and labels proteins so they will be working properly and arrive at the correct destinations? so whats the answer?
Answers
Answer:
[tex]\boxed {\tt Golgi \ apparatus}[/tex]
Explanation:
After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.
In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.
So, the correct answer is Golgi apparatus.
Golgi apparatus
The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

small population
Answers
Small population is the answer
Your welcome
According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.
What is the theory of natural selection?Natural selection is the procedure via which populations of living organisms acclimate and modify.
Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.
Natural selection leads to evolution.
Thus, genetic diversity best allow a species to survive environmental changes.
