1. In passive transport, what direction do molecules move?

2. In active transport, what direction do molecules move?

Answers

Answer:

In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.

Explanation:

Passive transport moves molecules from high to low concentration without energy. Energy-driven active transport moves molecules from low to high concentrations.

What is active and passive transport?

The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.

The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

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.

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.

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.
