Answer: shrink
A red blood cell placed in a medium that is hypertonic relative to its cytoplasm will shrink
Explanation:
Since the hypertonic medium has a higher concentration than the red blood cell, water will move out of the cell membrane of the red blood cell into the hypertonic medium.
Thus, after a while the continuous loss of water will cause the red blood cell to shrink (reduce in size)

In order to survive, all organisms must carry out 1) autotrophic nutrition 2) heterotrophic nutrition 3) enzyme-controlled reactions 4) the process of reproduction
Explanation:
(3) In order to survive, all organisms must carry out enzyme-controlled reactions.
Enzymes is the Most of the responses that happen in living life forms are chemical controlled. They are along these lines explicit in the responses that they catalyze one chemical will respond with particles of one substrate. The site of the response happens in a territory on the outside of the protein called the active site. Enzymes can be influenced by an assortment of elements, for example, temperature, pH, and focus. Chemicals work best inside explicit temperature and pH ranges, and imperfect conditions can make a protein lose its capacity to tie to a substrate.The most of the enzyme has an optimum pH range.All organisms need to carry out essential processes like organismal nutrition and enzyme-controlled reactions to survive, and maintain homeostasis. Organisms can be autotrophs or heterotrophs based on their mode of obtaining nutrients. Individual survival does not depend on the ability to reproduce, but does require energy transformation and stable internal conditions.
All living organisms require certain essential processes to survive. One of the foundational aspects is organismal nutrition, which determines how an organism acquires energy necessary for cellular functions. In terms of nutrition, living entities can be classified into groups such as photoautotrophs, who obtain energy from light, and heterotrophs, who gain energy by consuming other organisms.
Another key process is the ability to conduct enzyme-controlled reactions. These reactions are crucial for converting energy into a usable form (usually ATP) and facilitating the growth, repair, and reproduction of the organism. Additionally, organisms must maintain a stable internal environment, often referred to as homeostasis, which allows them to function effectively in varying external conditions.
While reproduction is an important life process for the continuation of a species, it is not essential for the survival of an individual organism. Therefore, not all organisms must reproduce to survive, but all must carry out enzyme-controlled reactions and maintain homeostasis to continue living.

Part A How do the potential energy and the kinetic energy change when the skateboarder is at the top or the bottom of the hill? Why do you think this change occurs?
Answer:
The potential energy (P.E) and the kinetic energy (K.E) are two types of distinct energy that is commonly observed in our day-today's life.
Usually, K.E is defined as a type of energy that is produced when an object is in motion. Where, as P.E is a type of energy that is stored in an object when that object is placed at a certain height.
In the given condition, when the skateboarder is at the top of the hill, then at that position, it is comprised of maximum P.E. As the he slowly comes down the hill, then the P.E gradually decreases, and the K.E gradually increases. This shows the P.E is slowly changing into the K.E. And as it comes down, the K.E increases, and eventually when he stops, then both the K.E and P.E becomes zero.
This changes occurs because energy can never be created nor destroyed, and it changes from one form to another.
Answer:
The potential energy and kinetic energy are always in flux. At the top of the hill, potential energy is at its highest and kinetic energy is at its lowest because the skateboarder stops for just a moment before being pulled down the hill by the force of gravity. At the bottom of the hill, kinetic energy is the highest because the skateboarder reaches maximum speed.

Osteoblasts, which are involved in bone formation, secrete osteoid, an uncalcified matrix that hardens into bone when mineral salts are deposited onto it. Trapped within this hardened matrix, osteoblasts then transform into osteocytes, the primary and most common cell type in mature bone.
Explanation:Osteoblasts, the bone cells responsible for forming new bone, secrete osteoid, which is an uncalcified matrix. This osteoid hardens within a few days as mineral salts are deposited on it, thus entrapping the osteoblasts within. Once entrapped within this matrix, the osteoblasts transform into osteocytes, which are the primary cells of mature bone and the most common type of bone cell.
Osteoblasts are found in the growing portions of bone, including the periosteum and endosteum, and they do not divide. They synthesize and secrete the collagen matrix and calcium salts, vital components for bone formation. This process is crucial in maintaining the mineral concentration of the matrix, improving bone density, and ensuring healthy bone growth.

Select the correct statement about blood flow. A) It is relatively constant through all body organs. B) It is measured in mm Hg. C) It is greatest where resistance is highest. D) Blood flow through the entire vascular system is proportional to cardiac output.
Answer:
The correct option is (D). The value of cardiac output in the case of the human heart is approx. 5 liters in a minute. The multiplication product of heart rate and stroke volume gives the cardiac output.
Explanation:
The blood flow serves as the parameter for the calculation of cardiac output. For the restoration of homeostasis, increase or decrease in the cardiac output leads to the simultaneous increase and decrease in the blood flow and pressure respectively. Also, the reduction of cardiac output and venous return signifies the higher value of the tidal volume. The associated parameters namely stroke volume and heart rate is also affected by certain factors. Some of them includes age, gender, contractility, heart size and duration of contraction.
Besides the flow of blood in the body depends on the oxygen requirement of the target cell.
The correct statement about blood flow - D) Blood flow through the entire vascular system is proportional to cardiac output.
Blood flowis the movement of blood through the vessels from arteries to the capillaries and then into the veins
reaches almost every cell in the body and returned to the lungs after removing oxygen.The heart is the organ that regulates this flow by pumping it to the various body parts.different parts of the body might have different flow rates.the amount of blood the heart pumps each minute which is called cardiac output is proportional to Blood flow through the entire vascular system.Thus, the correct statement about blood flow - D) Blood flow through the entire vascular system is proportional to cardiac output.

A scientist wants to change the DNA of a sexually reproducing organism and have the new DNA present in every cell of the organism. In order to do this after fertilization, she would change the DNA in the:_______1. Zygote2. Placenta3. Testes of the father4. Overies of the mother
Answer:
1. Zygote
Explanation:
A zygote is formed due to the fertilization of the female egg by the sperm cell.
A zygote cell is eukaryotic in nature. It is also a diploid cell because it is the coming together of a sperm cell which is a haploid cell and a female egg which is also a haploid cell.
A zygote cell contains DNA from both the sperm and the egg.
This is why in other to change the DNA of a sexually reproducing organism after fertilization and have an new DNA present in every cell of the organism, the scientist would have to change the DNA in the Zygote.
What is the name of the process where a material that is weak enough to flow will rises when it is hot and sinks when it is cool causing a circulation cell?
Answer:
Convection process
Explanation:
The process of convection is commonly takes place in the mantle portion of the earth and also at the atmosphere.
This process is usually defined as the process where the materials are heated at a high temperature, thereby making them less denser, and due to their low density they are gradually pushed upward into the upper zones. As the materials rises up, the density gradually increases due to the lowering of the temperature, and then the materials again sinks. This give rise to the formations of a circulating cell, which are commonly known as the convection cells.

High blood sugar Select one: a. Is termed hypoglycemia and stimulates alpha islet cells to produce glucagon b. Causes beta islet cells to produce glucagon c. Results in the the hypothalamus releasing insulin into the blood d. Stimulates the release of insulin by beta islet cells
Answer:Stimulates the release of insulin by beta islet cells
Explanation:High blood sugar level is called hyperglycemia.
It is very important for the body to regulate it's blood sugar level. This is done by hormones; insulin and glucagon.
When blood sugar rises, the beta cells of the pancreas produces insulin. This insulin reduces the blood sugar level by storing up glucose in the body.
High blood sugar level leads to diabetes.this condition occurs when the pancreas does not produce Insulin or produces insufficient insulin or the body becomes resistance to the activity of insulin.
Patients with diabetes have to take shots of insulin in order to keep their blood sugar level within the normal range.
When the blood sugar level is low, glucagon is produced by the alpha cells in the pancrease.glucagon converts stored glucose back into forms the body can use .
The correct option is (d). High blood sugar stimulates the release of insulin by beta islet cells.
When blood sugar levels rise, the beta cells in the pancreas are stimulated to release insulin. Insulin is a hormone that helps cells throughout the body absorb glucose and use it for energy. This process lowers blood sugar levels, counteracting the state of hyperglycemia (high blood sugar).
Option a is incorrect because hypoglycemia refers to low blood sugar, not high blood sugar. Hypoglycemia stimulates alpha islet cells to produce glucagon, which raises blood sugar levels.
Option b is incorrect because high blood sugar does not cause beta islet cells to produce glucagon; rather, it stimulates the production of insulin.
Option c is incorrect because the hypothalamus does not release insulin; insulin is released by the beta cells of the pancreas. The hypothalamus is involved in regulating many body functions, including hunger and thirst, but insulin release is not one of them.
The salivary amylase gene (AMY1) is present in two diploid copies in chimpanzees. Humans are known to have between 6-15 copies, an adaptation that is thought to be related to the high-starch diet of humans. This difference among humans is an example of:_______.
Evolution and Natural Selection
Explanation:
Salivary amylase gene (AMY1) copy number is correlated positively with salivary amylase protein levels, and that individuals from populations with high-starch diets have on average more AMY1 copies than those with traditionally low-starch diets. Higher AMY1 copy numbers and protein levels likely improve the digestion of starchy foods, and may buffer against the fitness-reducing effects of intestinal disease.
Chimpanzees did not feed much on starchy food and thus had only diploid copies of AMY1 gene. However, humans have 6-15 copies of AMY1 gene because of high consumption of starchy food. Therefore, as the evolution of chimpanzees occured, humans adapted itself to what changes in their habitat.
