Answer:
Nitrogen Fixation
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation.
Plants must use nitrates in a form of nitrogen, which is needed to make proteins for healthy growth.
What impact on plants due to depletion of nitrates or nitrogen?Nitrate plays a very important role in our ecosystem such that due to presence of nitrogen plants grow fastly and produce fruits of bigger size flowers too.
Plants absorb nitrates from water through their roots without nitrates, the amount of chlorophyll in leaves reduces.
Nitrate is a common inorganic ion found in plants which is required for proper growth and development of the plant and growers include the percentage of nitrates in their nutrient requirement to starts plant growth. Plants acquire nitrate through root intake from the soil and water around them.
Hence due to decreasing percentage of nitrogen plants are getting yellowed it means it produces smaller fruit.
In modern era farmers add nitrogen containing fertilizers which produce large amount of grains, foods and fruits which is also diseases free.
Therefore,Plants must use nitrates in a form of nitrogen, which is needed to make proteins for healthy growth.

Given what you've learned about scientific hypotheses, theories, and laws, do you think a scientific theory can become.
scientific law? Explain your reasoning.
Answer:
No. A law is something that happens without fail every time when being tested, or when it happens in nature. A law does not attempt to explain why the thing occurs, it only states it. A scientific theory is not something that can be tested on and will receive the exact same outcome each time. A theory attempts to explain an action seen in nature. Theories can be subject to change if new scientific data and research comes out, whereas laws cannot.

The type of ecological succession being described in the illustration is primary succession.
What is primary succession?It is a form of succession that occurs when an area that has never been occupied by any living organism becomes exposed and eventually gets colonized by living organisms.
It is quite different from secondary succession which happens when an area that has been housing biotic communities before gets disrupted by a major disturbance.
A new island formed by volcanic action has never housed any biotic community before. Thus, only primary succession can occur there.

some chains of carbon atoms bend when the carbon atoms:
A. form single covalent bonds.
B. form double covalent bonds.
C. form bonds with oxygen atoms.
D. form bonds with hydrogen atoms.
Answer:
Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature.

What is a cladogram?A cladogram is a diagram used in cladistics, which is a method of analyzing biological relationships based on shared, derived traits. It is a branching diagram that shows the evolutionary relationships among a group of organisms based on similarities and differences in their physical or genetic characteristics. The organisms are grouped into clades, which are defined by shared derived characteristics, or synapomorphies. Synapomorphies are traits that have evolved from a common ancestor and are present in all of its descendants.
Hence, the outgroup is a protozoa, and all of the traits that the mackerel has are a jaw, a segmented body, and a multicellular body. Lungs evolved first as frog has lungs and then hair evolved.

Which description best identifies the unique attributes of connective tissue?.
A. Connective tissues, unlike other tissues, lack blood vessels and blood.
B. Connective tissues transmit signals from one part of the body to another.
C. Connective tissue is characterized by an extracellular matrix.
D. Connective tissues are hard and inflexible, whereas soft, flexible structures of the body are made up of other tissue types.
Solution:
Connective tissue is characterized by an extracellular matrix. Thus, the correct option is C.
An extracellular matrix distinguishes connective tissue. A histologist analyzes a tissue slide and notices a densely packed parallel network of fibers. Squeezed between the fibers, a few cells can be observed.
What is connective tissue?Connective tissues are those tissue which help in support, protection, and structure. Additionally, connective tissue stores fat, aids in the movement of nutrients and other substances between tissues and organs, and aids in the repair of damaged tissue. Cells, fibers, and a gel-like material make up connective tissue.
Extracellular macromolecules and minerals, includes as collagen, enzymes, glycoproteins, and hydroxyapatite, make up the extracellular matrix (ECM), a three-dimensional network that provides structural and biochemical support to surrounding cells.
