Bacteria can convert nitrogen in the air into a form plants can use.

The earth atmosphere contain a huge amount of oxygen which is needed by plants. These Nitrogen can be converted into a form in which can be used by plants through a process known as nitrogen fixation.

Fixation is a process that converts nitrogen in the atmosphere into forms in which plants can use. Nitrogen can be fixed using fertilizer.

Also, bacteria can fix nitrogen into the soil naturally.

Answer:

They are different from rocky or terrestrial planets that are made of mostly rock. Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts! The gas giants have atmospheres that are mostly hydrogen and helium.

Explanation:

I hope this helps!

They vary from planets that are predominantly made of rock, such as rocky or terrestrial planets. Unlike solid planets, gas giants lack a clearly defined surface, there is no discernible line separating the atmosphere from the surface.

Telluric planets are another name for terrestrial planets. The Latin words terra and tellus, which both indicate Earth, are the source of the words terrestrial and telluric, respectively.

While the terrestrial planets were warmed by the sun's rays, the Jovian planets developed above the frost line.

Worlds that could float on water and worlds appropriate for manned missions were created under very distinct circumstances, but they have some striking similarities. Every world in our solar system is different.

Therefore, the atmospheres of the gas giants are primarily composed of hydrogen and helium.

Answer:

Explanation:

A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecule block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.

B. Two process that occurs during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a process known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has an effect on the variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene. 

C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which inhibits the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

Answer:

The mushroom is composed of two parts, the above ground part, and the underground part. Each part has its unique function and purpose in the life cycle of a mushroom.

Spores

It is usually released into the air and falls on the ground to start the life cycle of the mushroom. Seeds that acts as the mushrooms reproductive system.

Stem

A soft branch is supporting the mushroom’s cap.

Gill

Located under the cap, it produces the spore of the mushroom.

Mycelium

This part of the mushroom serves as the breeding ground of smaller mushrooms to grow.

Hypha

The microscopic filament that draws water and the organic matter necessary for mushroom development.

Volva

The remnant of a membrane that completely covers the immature mushroom.

Ring

A covering located under the cap surrounding the stem.

Cap

The upper part of the mushroom that protects the gills. It usually resembles a headdress, hence its name.

Each species has a special scientific name that is selected by the person or group that discovers it. The name typically conveys information about the species. Thus, option D is correct.

The kingdom is a smaller taxon than the recently added domain, which is a more expansive taxon. Similarities in outward physical characteristics serve as the foundation for the Linnaeus system.

Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations (known as genetic recombination).

Therefore, Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.

Explanation:

It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

Answer: The transformation of energy from eating the meal to the five mile run is from

Chemical energy --> kinetic energy--> thermal energy.

Explanation:

In nature, energy exists in various forms. These forms are inter- convertible, that is, one form of energy can be transformed into another form. Such energy transformations are governed by the laws of thermodynamics.

The first law of thermodynamics states that energy cannot be created or destroyed but may be transformed from one form into another.

Living organisms which comprises the biotic components of an ecosystem are energy converters. For example:

--> plants convert solar energy into chemical energy during photosynthesis

--> animals convert chemical energy into kinetic energy when they move about. This in turn is lost as heat energy when highly complex organised food molecules are broken down.

From the question, the student ate a nutritious meal ( CHEMICAL energy) which is converted to KINETIC energy as she took a five miles run ( as she worked). 'Work' here refers not only to physical activities but also to the various metabolic processes necessary to maintain life. And each time work is done, kinetic energy is converted to heat( thermal energy)
