What process is being used by the cell to move the molecules
The process that is being used by the cell to move the molecules is known as diffusion.
Diffusion is a method that has to do with the movement of substances within cells. It is also a method that's used for small molecules so that they'll be able to cross the cell membrane. It should be noted that the exchange of gas in the lungs of human beings operates through diffusion. For diffusion to take place, gaseous substances will have to go through the cell membrane in order to be able to go into a cell or out of the cell.Diffusion also takes place where there is a spread in particles. Diffusion is a movement from the region of a higher concentration to a low concentration.
In conclusion, the correct option is Diffusion.

Two characteristics of most plants are a root system and a shoot system. Most of the structures in these systems are common to all plants; however, there are some variations. Which structure can sometimes be found as part of the shoot system? Stems leaves roots flowers
Answer:
stems, leaves, flowers
Explanation:
There are two parts in the plants ----
1. the shoot system
2. the root system
Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.
The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.

Winter wheat is planted in the early autumn, grows over the winter when the weather
is colder, and is harvested in the spring. As the temperature drops, the composition of
the cell membrane of winter wheat changes. Unsaturated fatty acids replace saturated
fatty acids in the phospholipids of the membrane. Why is this a suitable adaptation?
Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.
Explanation:
Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.
What are unsaturated fatty acids?Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.
Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

B
AB
Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

Cactus plants, which grow in deserts, have a thick waxy coating that helps prevent water loss. The plants' sharp
spines provide protection from predators. Which of the following statements best explains why cactus plants
evolved to have these traits?
Answer:
C
Explanation:
Survival of the fittest shows that plants/animals with traits better suited for survival in their environments usually pass those traits to their offspring to help them survive.
Cactus plant with these traits were better able then other cactus plant to survive and pass these traits on to their offspring.
How do cacti adapt to the desert?Stems that can store water. Widespread or very deep root systems that can collect water from a large area or from very deep underground.
Why are cactus found in desert region?Cactus is found in dry and hot areas where rainfall is minimal and the land is arid. Their leaves are evolved into thorns to prevent transpiration and they can store water inside them.

When your muscle cells do not get enough oxygen, fermentation can create?
Answer:
Your muscles are forced to work without enough oxygen. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce.
Explanation:
When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do you think it is important to conserve the environment.
WILL NAME BRAINLIST!
Answer:
Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.
-These are some examples of how we can conserve the environment:
Recycle your rubbish and participate in or help organize recycling campaigns.
Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).
Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).
Swap toys, movies, and books instead of buying new ones.
Donate, recycle, and repair electronic devices (see how here).
Use less water when brushing teeth, taking a shower, or washing the dishes.
Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.
Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.
Use less paper by not printing unnecessary things and reading e-books.
Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.
Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.
Do not waste food and try to buy food that is grown locally and in season.
