Which best explains the role of plants in the nitrogen cycle?
Answer:
Assimilation
Explanation:
This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. ... When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
Does natural selection act on individual or does it act on something else ?
Answer:
huh
I don't know
Answer:
Yes and no
Explanation:
Natural Selection is the process of organisms adapting to the environment around them so yes individuals are effected through them adapting to the changes and they later pass their good traits to their offspring, and eventually the individuals who don't adapt die off, but the natural selection as a whole is just the process.

Osmosis is important to cells because _______ *
cells contain fluids that are mostly water
cells are filled with fluids that are mostly sugar
cells need to be kept cool
cells need food
( PLEASE ANSWER THIS ASAP!!!) Thanks!!
Answer:What is the main function of osmosis? Osmosis helps in stabilizing the internal environment of the organism by balancing the levels of water and intracellular fluids. Also, the nutrients and minerals enter the cell by osmosis which is necessary for the survival of cells.
Explanation:
Osmosis maintains the osmotic pressure in cells. the answer to this question is options A and B.
Osmosis is essential for the cells due to two reasons:
1. Cells are made up mostly of water-based fluids. The process of osmosis involves the movement of water molecules from a region with a lower concentration of solutes to an area with a greater concentration of solutes through a semipermeable membrane. This aids in preserving the equilibrium of water within and outside the cell, ensuring that the cell remains hydrated and performs as intended.
2. Sugar-based fluids are the main component of cells' fluids. Osmosis also affects how much sugar and other solutes are present inside cells, helping to control their concentration. Osmosis will cause water to enter the cell if the concentration of sugar inside the cell is higher than the outside, diluted the sugar, and maintain equilibrium.
Therefore the correct answer is options a and b.

Look at the plant in the picture below.
This plant is vascular but does not produce seeds. To which of the following groups does this plant belong?
A. flowering plants
B.
conifers
C.
ferns
D.
mosses
The following groups of plant belongs to ferns.
What are the characteristics of ferns?A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers.
In their natural environment, most ferns grow in humid forests or on the bank of a water source, so they generally require very moist soil. Even fern varieties that become drought tolerant as they mature usually require moist soil at planting time.
Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.

an adaptation is A a trait that helps an organism survive in its enivironment
Answer:
True
Explanation:
The given statement is true. An adaptation is any characteristic that helps an organism survive or reproduce. As the environment changes, organisms that inhabit it have to change as well in order to survive. The changes they go through can be physical or behavioral. For example, giraffes have very long necks so that they can reach the leaves of tall trees, and birds have very light bones so that they can fly. This is how species continue to thrive for a very long time.
Water is an adhesive substance. This means that water particles
A. are attracted to other types of particles.
B. are repelled by other water particles.
C. are attracted to other water particles.
D. are repelled by other types of particles.
Answer:
A
Explanation:
are attracted to other types of particles.
Adhesion is the term for the attraction of substances between distinct phases. It uses the attraction of water to other polar compounds, as an illustration, hence option a is correct.
What is the characteristic of water?Cohesion is the tendency of particles to cling together, it uses the attraction of water molecules to one another.
Water has a characteristic called cohesion in which water molecules form bonds with one another. As a result, surface tension develops and raindrops start to form.
Water molecules can interact with other molecules through adhesion, this enables water to adhere to surfaces like windows and other things.
Therefore, water is a strong adhesive that adheres effectively to many different materials, hence option a is correct.

Two offspring from same parents can have different phenotypes. How is this possible?
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
Explanation:
Overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.
What is heterozygote?Heterozygote is defined as a person, animal, or other thing possessing a pair of different alleles of a specific gene, one of which is dominant and the other recessive. One normal allele and one mutated allele, or two distinct mutated alleles, can make up a heterozygous genotype.
The explanation is connected to the fact that each parent has two different gene pools. Furthermore, only 50 percent of each parent's DNA is transferred to their offspring. and that the portion that is passed down is random. Every child has a unique set of genes thanks to the interaction of all these influences.
Thus, overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.
