Explanation:

part of the nitrogen cycle

Denitrifying bacteria turns nitrogen back into nitrogen gas. The correct option is A.

Any natural or artificial process called nitrogen fixation causes free nitrogen, a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites.

Chemically, nitrogen fixation transforms atmospheric nitrogen into ammonia, which is ingested by living things.

In essence, nitrogen fixation transforms atmospheric nitrogen into a form that plants can use more easily.

Nitrate is transformed back into nitrogen gas by denitrifying bacteria, which then reenters the atmosphere. Runoff and fertilizer-related nitrogen enters the ocean, where it interacts with marine food webs.

Thus, the correct option is A.

A disadvantage of using nuclear power is D. Nuclear power produces radioactive waste.

Nuclear power is a controversial topic, with proponents arguing that it is a clean and efficient source of energy, while opponents point to the risks of accidents and the dangers of radioactive waste.

One of the main disadvantages of nuclear power is that it produces radioactive waste. Radioactive waste is a byproduct of the nuclear fission process, and it can remain radioactive for thousands of years. This makes it difficult to store and dispose of safely. Another disadvantage of nuclear power is that it is expensive to build and operate nuclear power plants.

Answer:

A

Explanation:

Answer:it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.

Explanation:

Answer:

The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Answer:

Are usually present, but are no longer functional.

Explanation:

Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.

Good examples in humans are the tail bone, wisdom teeth, and the appendix.

Answer:

Ultraviolet (UV) photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent bases bond with each other, instead of across the “ladder.” This makes a bulge, and the distorted DNA molecule does not function properly.

Explanation:

Water is extremely valuable to all living things. It is especially important for plants to perform photosynthesis which is one of the smallest most valuable biochemical mechanisms known to life, in addition, plants are the main source of nutrients for many creatures. Without photosynthesis, plants would not be able to produce oxygen. In addition, plants are classified as producers, the most basic level of the flow of energy in every ecosystem and are the main reason energy from the sun can then be converted into usable energy for primary consumers, secondary consumers, and tertiary consumers. For humans, water is extremely important to keeping our bodies in homeostasis while the billions of chemical reactions take place in our bodies in just minutes. A human can not live without water for more than three to four days. If there was a deficiency of water both plants, animals, and humans would be greatly affected. Without water, plants would not grow, so no conversion CO2 to 02 and harnessing energy from the sun. Next animals that depend on both water and plants would have a decrease in population. Followed by the depletion of all else consumers. You remove a resource this valuable and there is no coming back.

all cells do not contain a nucleus

Answer:

This question is incomplete

Explanation:

However, as described in the question. each cell organelle has specialized function that assists the cell carry-out it's own function as a whole. Cell organelles include cell membrane, smooth and rough endoplasmic reticulum, vacuole, golgi complex, lysosomes, nucleus, mitochondria, chloroplasts among others.

Of these cell organelles, only three were mentioned in the question

Nucleus: This houses the chromosome which stores genetic material. This organelle is found in plant and animal eukaryotic cells. Indeed, eukaryotic organisms are sometimes described as organisms that have well defined nucleus.

Mitochondria: They are found in most plant and animal eukaryotic cells. They are usually referred to as the power house of the cell as they provide energy-rich chemical compounds (called ATP) for the cell's activities.

Chloroplasts: These are cellular structures/organelles that are found only in  green plants - they are cellular machinery for photosynthesis in plants. They also contain the green pigment called chlorophyll which is responsible for the green colour of green plants.

The type of the cell in which the organelles mentioned in the question are listed above.

Answer:

burning fossil fuels and decomposition of dead organisms

Explanation:

A significant amount of the carbon in the biosphere is returned to the carbon cycle through decomposition by fungi and bacteria. Much of what is not decomposed becomes fossil fuels. When humans burn fossil fuels for energy, carbon is returned to the atmosphere.

The process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A, as when an animal dies, its body is broken down by decomposers, such as bacteria and fungi.

The decomposition process is essential for the cycling of carbon in the environment. When an animal dies, the organic molecules that make up its body become available to decomposers. These decomposers use enzymes to break down the complex organic molecules into simpler compounds, such as sugars, amino acids, and fatty acids.

Hence, the process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A.

Answer:

All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species .
