O D. The cuticle protected reproductive structures.

Answers

Answer:

a

Explanation:

The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.

What is transpiration?

Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.

The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.

To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.

Thus, the correct option is A.

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

Answers

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.

B. It attacks neurons in the nervous system and causes paralysis
C. It attacks and destroys certain cells in the bodies of its host organisms.
D. It has viral DNA that is transmitted through direct contact with infected persons

Answers

Answer: A

It has viral DNA that remains dormant until environmental conditions are right.

HIV is a unique human RNA virus, capable of infecting cells of the immune system.  

Plz mark brainliest:)

It attacks and destroys certain cells in the bodies of its host organisms. Therefore, option (C) is correct.

What is HIV?

HIV, or human immunodeficiency virus, attacks and destroys a specific type of immune cell called CD4+ T cells. These cells play a critical role in the immune system, and their destruction leads to a loss of immunity and the development of acquired immunodeficiency syndrome (AIDS). HIV is unique in that it specifically targets and attacks these cells, leading to a gradual decline in the body's ability to fight off infections and diseases.

HIV is primarily spread through sexual contact, but can also be spread through sharing needles or from mother to child during pregnancy, childbirth, or breastfeeding. HIV can lead to AIDS (Acquired Immunodeficiency Syndrome) if left untreated.

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?

Answers

Answer:

Water molecules will still be able to move across the cell membrane but at a slower rate.

Explanation:

D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:

Answer:

Water molecules will still be able to move across the cell membrane but at a slower rate.

Explanation:

The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

Iron, water, and sugar are examples of matter that are nutrients.
True or false

Answers

Answer:

false

Explanation:

water is just good for you and some sugars are good

Iron, water, and sugar are examples of matter that are nutrients. So the statement is true.

What are nutrients?

The substances in food known as nutrients give us the energy needed for development, repair, and other vital living activities. Although not all nutrients are energy-producing, they are all required in one way or another. There are two groups of these nutrients:

macronutrients, which the body needs in huge quantities.micronutrients, which the body needs in minute amounts.

The environment may provide the aforementioned nutrients. Macronutrients give a living thing the energy it needs to run its metabolic system. They offer enormous energy that can be processed and used to produce energy. Fats, proteins, and carbs are examples of macronutrients.

Micronutrients supply the necessary building blocks for metabolism to function. To regulate bodily processes, they also create new tissues and replace ones that have been destroyed. Calcium, iron, vitamins, minerals, iron, and vitamin C are examples of micronutrients.

Therefore, iron, water, and sugar are examples of matter that are nutrients.
