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
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:
temperature balance

PLEASE HELP :) What is the difference between Gross Primary Production and Net primary production in simple terms? (If you could also provide an example I would really appreciate it.) Thank you for your time!
Answer:
Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. ... Net primary production is directly related to ecosystem conditions.

what is crop fallowing?
Please reply fast I need to do my biology assignment !!!
Answer: A field, or several fields, are taken out of crop rotation for a specific period of time, usually one to five years, depending on crop. Fallowing soil is a method of sustainable land management that has been used by farmers for centuries in regions of the Mediterranean, North Africa, Asia and other places.
Explanation:
There is a relationship between the number of prey organisms and the number of predator organisms in an ecosystem. Identify this relationship and explain how it occurs.
Answer:
This relation should be called Predator-Prey relationship. In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. they affect the success and survival of each other’s species. The predator prey relationships greatly affect the populations of each species, for example if we take lynx as predator and hare as prey after some time the population of hare will start declining and population of lynx will increase because hare is being EATEN and lynx is the predator here.

summarize the importance of stem cells
Answer:
Stem cells can become almost any cell in the human body.
Explanation:
This is important because in embryonic development, the body uses stem cells to form each individual part. For example, a single stem cell could become a heart cell, or brain cell, or a blood cell, or more. This is also important for possible treatments. In order to heal damaged or diseased bone tissue, blood stem cells can be taken out of the same person and used to fix the tissue. This allows for a lower rejection rate sense the cells used to fix the tissue were already part of the person's body.
Vernon is using the diagram shown below to develop a model of photosynthesis. The letters A, B, and C each represent a reactant or product of the process.
In the light-dependent reactions, light strikes the oval thylakoids. Compound A enters the thylakoid, and compound B leaves it. In the light-independent reactions, compound C enters a cycle in the stroma, and sugars leave the cycle. ATP and NADPH cycle between the two sets of reactions.
Should water (H2O) be included in the model as a reactant or product? If so, how should it be included?
A. Yes, as reactant A.
B. Yes, as product B.
C. Yes, as reactant C.
D. No, it should not be included.
Photosynthesis is the process of preparing food in the presence of light, water, and carbon dioxide. Photosynthesis can be light-dependent or light-independent reactions.
The correct answer is:
Option A. Yes, as reactant A.
The mechanism can be explained as:
1. Light-dependent reactions convert light energy into chemical energy.
2. The light-dependent reactions require water and light to yield oxygen, hydrogen, and energy molecules.
3. The light is used to break down the molecule of water into oxygen and hydrogen when the light strikes the thylakoid.
4. The ATP is generated in the stroma of the thylakoid membrane. The excited electrons released during the splitting of water is utilized to produce high-energy molecule.
Thus, water molecule should be used as a reactant because it yields products.

An experiment is carried out to determine how different PH values of soil will affect the growth of tomato plants. In this experiment, the dependent variable could be the
A) height of the tomato plants
B) pH of the soil
C) specific variety of tomato plants used
D) pH of enzymes is tomato leaf cells
Answer:
A. Height of tomato plants
Explanation:
The dependent variable in an experiment is the variable that the experimenter measures or the variable that responds to changes made to the independent variable. The dependent variable is dependent on the independent variable.
In this experiment conducted to determine how different PH values of soil will affect the growth of tomato plants, the growth of the plants is measured by their height. Hence, the dependent variable is the HEIGHT OF THE PLANTS.

Cameron reads in his textbook that animal cells are composed of 90 percent water and 10
percent protein, carbohydrate, nucleic acid, lipid, and other molecules. He learns that
homeostasis is the process by which this composition is maintained. How does an organelle
in an animal cell control the content of water and other material in the cell?
F The cell wall splits apart to allow water and materials to enter the cell and waste
products to leave the cell.
G The cell membrane is selectively permeable, which controls the movement of materials
in and out of the cell by passive and active transport.
H Vacuoles in the cell open and draw in only the materials needed from outside the cell.
J
Lysosomes move out of the cell to capture and bring back needed materials.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.
Answer:
The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.
Explanation:
According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.
The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.
Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.
Kayla summarizes the cell theory to her class. She states that all organisms are made up of one or more cells. Which pair of statements correctly completes her summary?
A. All cells are the same size, and the cell is the basic unit of all organisms.
B. All cells come from existing cells, and all cells have the same parts.
C. The cell is the basic unit of all organisms, and all cells come from existing cells.
D. The cell is the basic unit of all organisms, and all cells have the same parts.
Answer:
C
Explanation:
Cells are a basic unit of life and that without cells you don't exist as a living being. Also, all the other answers have a flaw in them like in question A... not all cells are the same size. For question B and D... not all cells have the same, parts or organelles since for plants they have chloroplast while animals don't. Eukaryotes have membran- bound organelles and a nucleus while... a Prokaryote doesn't etc...

Answer:
The Epipelagic Zone (sunlight zone)
Explanation:
The depth of this zone is about 200 meters (656 meters) below the ocean's surface. Phytoplanktons dwell there because sunlight penetrates this zone which facilitates the process of photosynthesis.

Does the endocrine system interact with any other organs!!! PLEASE HELP QUICK!!!
Answer:
yes,
The brain sends a message to the endocrine system (via the pituitary gland) for the adrenal glands to secrete their hormones cortisol and adrenaline. These hormones flood the circulation and affect other organ systems throughout the body, including the cardiovascular, urinary, sensory, and digestive systems.
