Answer:
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle
discuss the importance of vernalization
Answer:
The important of vernalization it includes early flowering there by shortening the vegetative cycle of the plants (it is a production of more than a one crop in one year) the winter variety crops can be converted to spring variety (it's the protection from the freezing of injury) it helps in the increasing of yield of the plants.

In the _____ the virus can reproduce so rapidly that it causes the cell membrane to disintegrate.
a lysogenic
b lactic
c lymphatic
d lytic
In the lytic cycle, the virus introduces its genome and replicates after that it assembles a new virus body and ruptures the cell membrane, hence option d is correct.
What are the lytic and lysogenic cycles?In a lytic cycle, the virus transfers its genome into a host cell and starts replication by seizing control of the host's cellular machinery.
When the infection is finished, the host cell is lysed, releasing the freshly duplicated and assembled virus particles into the surrounding waters.
The virus replicates by integrating its genome with the genome of the host cell during the lysogenic cycle, which is also known as a non-virulent infection.
Therefore during the lytic cycle, the virus-cell membrane is disintegrate and the lysogenic cycle happens without killing the host, hence option d is correct.

In rabbits, black fur (B) is dominant to white fur (b). A purebred black furred male is bred with a female that had the recessive white fur
Answer:
All the offsprings will be black-furred (Bb)
Explanation:
This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.
According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:
BB - B only
bb - b only
Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:
Bb, Bb, Bb, Bb
All Bb (heterozygous) means that all of the offsprings will be black-furred.

why terrace farming is advantageous in hilly and mountains
Answer:
The major benefit, of course, is the conservation of soil and water. Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.

Evaluate whether two places at the same altitude would have the same climate.
Answer:
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. Farther inland, the climate is influenced by cold or hot air from the land. So, it depends on where you are on the world.

Answer:
A chart
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A chart is a representation of data which visualizes potential relationships between variables. Some examples include pie chart, bar chart, etc.
A bar graph also known as a bar chart can be defined as the graphical representation of data (informations) by using vertical columns or rectangular bars. When a data set is observed, a bar chart can be used to graphically represent or record the total or overall amount of information contained therein.

DNA is made up of pairs of nitrogenous bases. Which of the following
nitrogenous bases is paired correctly?
A. Guanine-guanine
B. Adenine-thymine
C. Adenine-guanine
D. Cytosine-thymine
DNA is made up of pairs of nitrogenous bases. The nitrogenous bases is paired correctly is Adenine-thymine. Thus, option B is correct.
How DNA is made up off?The DNA is formed by the nitrogen bases adenine, cytosine, guanine and thymine. The pairings between bases are -Adenine with Thymine and Cytosine with guanine. Nitrogenous bases are heterocyclic, planar, and relatively water-insoluble aromatic molecules.DNA consist of two types of nitrogenous bases-Purines and Pyrimidines.
Purines are the two common purine bases found in DNA are Guanine and Adenine. Pyrimidine-The two common pyrimidine bases found in DNA are Thymine and Cytosine.
According to the base-pairing rule in DNA- Adenine (purine) pairs with Thymine (Pyrimidine) and Guanine (purine) pairs with Cytosine. Adenine pairs with Thymine with two hydrogen bonds and Guanine pairs with Cytosine with three hydrogen bonds.
Thus, option B is correct.

Species richness is the number of different species represented in an ecological community, landscape or region.
What is species richness?
Species richness is the number of species within a defined region. The species richness of a region is obtained through sampling or via a census.
What determines the number of species in a community?
The number of niches present in a community determines the number of species present. If two species have the exact same niche (e.g. the same food demands) then one species will outcompete the other.

A sea otter is critical to the functioning of the ecosystem in which it lives. It affects the
survival and abundance of many other species in its community. It is a(n) species.
Answer: A keystone species.
A sea otter is critical to the functioning of the ecosystem in which it lives. It affects the survival and abundance of many species because it is a keystone species. Option a is the correct answer.
What is an ecosystem?Living and nonliving organisms coexist in an ecosystem. Living are called "biotic" factors, while non-living are called "abiotic." Different ecosystems have different biotic organisms, such as animals and plants. In some ecosystems, a particular species has more importance. They are called keystone species.
This species is key to the functioning of the ecosystem. Without the keystone species, the ecosystem would not function well. The statement's example is the role of the sea otter.
Some species are found in abundance in some ecosystem. If they are hunted for their resources, their numbers will decline. This type of species is called an endangered species.
Hence, the sea otter is a keystone species. It maintains the survival of many other species in the ecosystem. Option a is correct.
