Explanation:
During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sent to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario? A. Hormones act as signal molecules between all body systems. B. Exercise is important for the body to function properly. C. Nerves transmit and respond to every major system in the body. D. Increased heart rate and blood flow decrease oxygen supply.
A. Hormones act as signal molecules between all body systems
Peripheral Chemoreceptors (Carotid + Aortic Bodies) and Central Chemoreceptors in the Medulla Oblongata detect high Carbon Dioxide levels in the blood during exercise. The respiratory centre in the Medulla Oblongata + PONS stimulate the intercostal muscles and the diphragm to contract in order to increase the rate and depth of breathing as to decrease levels of Carbon dioxide in the blood.
The thyroid gland secretes thyroxine which speeds up metabolism (the rate at which cells use glucose)
Answer:
B. Nerves transmit and respond to every major system in the body.

lant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life processes where does it occur?.
Answer:
Two processes were described in this question, hence, the location of the two processes are as follows:
synthesize energy-rich organic molecules- CHLOROPLAST
Break them down to extract energy- MITOCHONDRIA
Explanation:
Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.
However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.
Kala added a spoon of yeast and hot boiling water to knead bread dough, whereas Rupa added warm water to knead the dough with yeast in it. Both of them made bread. Whose bread will be soft? Why?
Answer:
I think Rupa's bread will come out softer than Kala's.
Explanation:
Using hot boiling water to activate yeast can kill it. Instead of being absorbed by the protein, the hot water is absorbed into the starch molecules.
It is better to use warm water to get a more fluffy bread.
Soft bread is soft because CO2 produced by yeast and water that gets turned to steam by the baking process gets trapped into pockets by a mesh of gluten, causing the dough to expand. The dough then solidifies, keeping its shape. If your bread is not soft then it hasn't expanded enough for one or more reasons.

increases the lethality of T-cells.
eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.
transport proteins in the cell membrane play an important role in cell transport by
Answer: Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.
Explanation:
Membrane transport proteins play a crucial role in the movement of solutes across biological membranes, including ions, nutrients, neurotransmitters, and a wide range of medications.
What function do transport proteins provide in living membranes?
The cell membrane contains transport proteins that enable the selective transit of particular molecules from the surrounding environment. Each transport protein recognizes a certain chemical only (indicated by matching colors)
The two main kinds of membrane transport proteins are carrier proteins and channel proteins. The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane.

Explanation:
Why do developed countries have lower growth rates than less-developed countries? higher birth rates lower death rates higher death rates lower birth rates
The correct answer is D. Lower birth rates
Explanation:
The growth rate is determined by how fast the population of a country or a zone increases. This factor is higher in developing countries than in developed countries. One factor that contributes to this is the low birth rate in developed countries as people have fewer children in these countries, and therefore there are fewer births per year than in developing countries. This is influenced by the accessibility to contraceptive methods, higher education levels, and cultural values. Also, fewer births mean the population will grow slowly, and therefore the growth rate is lower.
Answer:
lower birth rates

Which of the following is NOT one of the three global wind patterns?
A. Polar Easterlies
B. Westerlies
C. Trade Winds
D. Interglacial Winds
Answer:
I believe that the correct answer is d. Interglacial Winds
Explanation:
Please mark as brainiest ! Hope this helps!
Polar Easterlies, Westerlies and trade winds are the three main global wind patterns. Interglacial winds are not a type of global wind patterns. Thus, the correct option is D.
What are global wind patterns?Global Wind Patterns is mainly the result of a thermodynamic principle and the Coriolis effect due to the counterclockwise rotation of the planet earth. Warm air around the equator is lifted that creates a suction effect for air masses coming from different latitudes.
The three important global wind belts are polar easterlies, westerlies, and trade winds. The polar easterlies flow from the north and south poles towards 60° north and south, respectively. They are very cold and dry winds. The westerlies are present between 30° and 60° north and south of the Equator.
Therefore, the correct option is D.

What is the Hepatic Portal Vein?
Answer: The hepatic portal vein is one of the most important vein that receives blood from the body and transports it into the liver for filtration and processing. This vein is part of the hepatic portal system that receives all of the blood draining from the abdominal digestive tract, as well as from the pancreas, gallbladder, and spleen.
‘Hepatic’ means of or relating to the liver, therefore the hepatic portal vein is a blood vessel that sends nutrient-rich blood from the gastrointestinal tract and spleen to the liver, but also delivers toxins to the liver that will be chemically modified in the proces of detoxication
Answer:
Explanation:
hepatic portal vein is located in the upper right quadrant of the abdomen. It is typically 8 centimeters long in adults. The portal vein is responsible for carrying blood from the GI tract, gallbladder, pancreas, and spleen to the liver.The hepatic portal vein originates behind the neck of the pancreas and is usually formed by the convergence of the superior mesenteric vein and the splenic vein, referred to as the splenic-mesenteric confluence.
