a. True
b. False

Answers

The statement above is TRUE.
Immunological memory is a characteristic of the immune system, which give it the capacity to remember antigens on pathogens, tumor cells, etc, and thus is able to raise greater immunological response against them. Immunological memory is formed by earlier exposure to an antigen. This antigen will be remembered by certain leukocytes and antibodies in the immune system if the body is exposed to it again.

Answers

the answer is B. i hope this helps

Answer:

Option B, It generates steam, which turns a turbine, powering a generator

Explanation:

In a nuclear power plant, heat generated through the nuclear fission reaction is used to convert water into steam. The steam formed possess kinetic energy which is then directed towards the turbine of the generator. This high speed steam rotate the turbine which in turn rotates coil connected to it. This coil is placed between two magnets. Thus, an AC current is produced by the coil when it rotates between the magnets.

Hence, option B is correct.

Which molecule do plants use to store extra glucose

A.Glycogen
B.Lipid
C.Starch
D.Myosin

Answers

starch

"The storage form of glucose in plants is starch. Starch is a polysaccharide. The leaves of a plant make sugar during the process of photosynthesis. Photosynthesis occurs in light (photo = light), such as when the sun is shining."

Plant storage polyglucan that gathers in plastids is called starch. It is used to store extra glucose. Therefore, option (C) is correct.

What is the main role of starch in plants?

A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. . It is made up of two polymers with different structures, amylose and amylopectin, and it serves a variety of roles in influencing plant yield. Most green plants synthesize this polysaccharide as a form of energy storage. It prevents carbon deprivation at night in leaves by acting as a buffer.

In order to provide the plant with a reserve food supply, starch is synthesized in the green leaves of plants using extra glucose produced during photosynthesis. The stroma of the chloroplasts and the cytoplasm of leaves both store starch.

Explain how the use of fertilizer can have a negative impact on the environment.

Answers

negative impact on the environment is unnatural, fake

Excessive fertilizer use can lead to environmental issues, including water pollution, soil degradation, and harm to ecosystems.

While fertilizers are essential for boosting crop yields and agricultural productivity, their excessive or improper use can have several negative environmental impacts:

Water Pollution: When excess fertilizer is applied to fields, rainwater can wash the nutrients into rivers and lakes, causing nutrient pollution. This can lead to algal blooms and oxygen depletion, harming aquatic ecosystems.

Soil Degradation: Overreliance on fertilizers can reduce soil fertility, disrupt natural nutrient cycling, and lead to the accumulation of salts, potentially rendering soil less productive.

Loss of Biodiversity: Nutrient runoff from fertilizer can alter the composition of local ecosystems, favoring certain species while negatively impacting others. This can lead to biodiversity loss.

Greenhouse Gas Emissions: The production and use of synthetic fertilizers contribute to greenhouse gas emissions, which can contribute to climate change.

Health Risks: Excessive nitrates from fertilizers can contaminate drinking water, posing health risks, especially to infants.

The gyri and sulci on the brain greatly increase the brain's surface area. how do you think this increase in surface area relates to improved brain function? 2. can you think of another organ in the human body that is shaped specifically to increase surface area? how does this organ's structure relate to its function in the body? (hint: think about those few bites of pancakes you ate in the opening paragraph.) 3. why do you think you created the frontal lobe of the cerebrum in the same color clay you used to create the three muscles of the face? 4. from the names alone, what do you think are the specific functions of the motor cortex and the sensory cortex of the brain? 5. what do you think the up and down arrows you carved into the spinal cord are meant to represent? 6. how do the central nervous system and the peripheral nervous system work together to control the body?

Answers

1) The way how this increase in surface area relates to improved brain function: The more surface area increased, the more chances of connection between neutrongs there are. Therefore, there is more possible learning (which is improved function).

2) According to the hints, I would say that this question is about the small and large intestine. Keep in mind that the the intestines are needed to allow nutrients and water to diffuse into the body (during the process of expelling waste). Also,take into account that the greater the surface area, the faster the absorption will be processed.

3) You created the frontal lobe of the cerebrum in the same color clay you used to create the three muscles of the face because the main function of prefrontal cortex in the frontal lobe is to be responsible for expression of a personality. This will require the muscles that you put in the face of a model.

4) The specific functions of the motor cortex are: To deal with motor skills (responsible for any type of movement).
The specific functions of the sensory cortex: To deals with sensory things (responsible for sensory perseption of things surrounding people).

5) The up and down arrows you carved into the spinal cord are meant to represent the movement of different nerve signals. These signals, which are slso called action potential, are coordinated movements of sodium and potassium ions that are psocessed across the nerve cell membranes.

6) The wayhow the central nervous system and the peripheral nervous system work together to control the body is shown here: the peripheral nervous system alerts communication to the central nervous system of things with the limbs and organs of a body.

What effect will an animals eating less during hibernation most likely have it maintenance of cellular homeostasis ?

Answers

Final answer:

Eating less food during hibernation helps animals conserve energy, rely on fat reserves, and minimize exposure to dangers.

Explanation:

During hibernation, animals experience a decrease in activity and metabolism, leading them to eat less food. This reduction in food intake has several effects on the maintenance of cellular homeostasis. First, it helps the animal conserve energy by reducing metabolic processes, such as protein synthesis and cell division. Second, it allows the animal to rely on stored fat reserves, which can be broken down and used as an energy source during hibernation. Finally, by reducing the need for food, hibernating animals can minimize the risk of exposure to predators or other dangers that may be present during winter months.
