Answer:

Pasture and cropland occupy around 50 percent of the Earth's habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.

The benefits are:

early agriculture

Morden agriculture's opportunity

Development in farming sustainability

Farmers improve their communities

Answer

Enzymes are proteins, which have a specific 3D tertiary structure, with a specifically shaped active site. The active site can only bind one substrate to form an enzyme-substrate complex, so can therefore only catalyse one reaction.

Answer:

In the nitrogen fixation process, nitrogen fixing bacteria converts the N2 in the atmosphere into NH3 (ammonia). This bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. ... From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification

The volume of a pair of dice could be gotten by measuring the

sides and calculating it via length/width/height. A second manner

would be displacement, where the dice are placed in a liquid with a

known density, and the mass of the liquid displaced is used to

determine volume.

Answer:

A mutation could have no effect on the organism that inherits the mutation because of the chances of the organism's parents/producers. One parent may be dominantly having the mutation while the other parent may have the mutation but does not display its effects, thus labeling this parent as a carrier of the trait/mutation. Drawing a punnet square would best be used to describe the possibilities of each offspring and how each carries or shows the mutation inherited from their parents.

Explanation:

There are two stages to photosynthesis: Reactions of light and darkness. Light-Reaction takes place in thylakoid membrane.

Autotrophic plants produce their own food through a process called photosynthesis. Sunlight, chlorophyll, CO2, and water are four crucial components needed for this process.  It is a response that is light dependent.

In plants and some other creatures, a process known as the "Dark Reaction" harnesses the energy from the sun to change carbon dioxide and water into glucose (a sugar) and oxygen.

Therefore, a sequence of chemical events known as the "Light Reaction of Photosynthesis" are what is needed for the pigment found in leaves, such as chlorophyll, to transform light energy into chemical energy in the form of ATP and NADPH.

In the same way, cells during development also express specific sets of genes. These patterns of gene expression cause cells to communicate with neighboring cells, resulting in coordinated development into a multicellular organism.

Answer:

The correct answer is D. Silent

I can assure this is the correct answer because I took either the test or review, I don't remember but yeah I know its correct also, because of the other person so be sure to say thanks to them before me!

Hope I helped! <3

A silent mutation is a point mutation and not a frameshift mutation. Therefore, the correct statement is option D.

Mutagens are agents causing mutations in DNA sequence. Point mutations are due to a change in a single nucleotide base in a DNA sequence and frameshift mutations are due to changes that are the result of the insertion or deletion of nucleotide bases, thereby, shifting the reading frame of the sequence and the way is changed in which it is translated into a protein.

A silent mutation is a point mutation that does not change the amino acid sequence of a protein, as the mutated codon still codes for the same amino acid, thereby, not affecting the function of the protein.

Insertion and deletion mutations are frameshift mutations as they alter the reading frame of the sequence which results in a completely different amino acid sequence.

Therefore, the silent mutation is a point mutation.

The enzyme dicer chops dsRNA molecules into small pieces of miRNA and siRNA. The correct option is B.

What is Dicer?

Dicer is an enzyme involved in RNA interference (RNAi), a cellular process that regulates gene expression.

Its primary role is to cleave double-stranded RNA (dsRNA) molecules into smaller fragments.

These fragments are typically around 21-25 nucleotides in length and serve as the building blocks for two types of small RNA molecules: microRNA (miRNA) and small interfering RNA (siRNA).

Thus, the correct option is B.

Carrying capacity is a constant that equals population size at the equilibrium point. The term that best describes the continued stability of the population is option B, carrying capacity.

---------------------------------

Populations that exhibit the logistic growth model depend on density.

Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate.

The population per capita growth rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get equal to each other.

Assuming that population size is N, when

The sigmoid curve represents the logistic growth model.

The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent.

Dense-independent factors might be human impact or natural disasters (fires, volcanic eruption, flooding).

In the exposed example we have a small population of deer that could grow and increase in size because of the absence of its predator.

This deer population exhibited continuous growth until it reached a certain point in which it remained stable.

This point is the carrying capacity.

At this point N = K ⇒ the deer population stoped increasing its size because it reached the environmental maximal capacity.
