Answer: The correct answer to the question bus option B
DISSIMILATORY NITROGEN REDUCTION .
Explanation: When we talk about Dissimilaritory nitrogen reduction we simply mean an alternate form of respiration which occurs in the anoxic grown bacteria example purple photosynthetic bacteria.
Dissimilaritory nitrogen reduction is actually a type of denitrification which entails the denitrifying bacteria using nitrates or nitrites as electron acceptor and then reduce them to nitrogen gas. A series of intermediates are formed in this process of which Nitrous oxide is one of them, Nitrous oxide is a green house gas.
However,the main difference we can see between assimilatory and dissimilatory nitrogen reduction is that in the assimilatory pathway of nitrate reduction, ammonia will be formed which is utilized for the biosynthesis as a source of nitrogen. While in dissimilatory pathway, ammonia formation do not take place.

Meteorologists refer to the water vapor in the atmosphere as
Answer:
^^ The answer is below ^^
Explanation:
Water vapor is water in the gaseous phase. Meteorologists have defined several different terms to express the amount of water vapor in air. ... Specific humidity is the ratio of the mass of water vapor in a sample to the total mass of the moist air, including both the dry air and the water vapor.
Meteorologists refer to the water vapour in the atmosphere as moisture or humidity.
What are water vapours?The atmosphere is continually being circulated with water. Water evaporating from the surface of the Earth rises into the sky on heated updrafts. When the air is driven by the wind, it condenses into clouds before returning to Earth as rain or snow. This cycle is vital to how heat and energy are moved around our globe from one location to another and from the Earth's surface to the atmosphere.
The most significant greenhouse gas found in the atmosphere is also water vapour. The heat emitted from the surface of the Earth is absorbed by water vapour molecules in the lower atmosphere. In turn, the molecules of water vapour emit heat in all dimensions. The Earth's surface receives some of the heat back. So, in addition to sunshine, water vapour serves as a second source of warming for the Earth's surface.
Therefore, meteorologists refer to the water vapour in the atmosphere as moisture or humidity.

Is water and its properties important in homeostasis for humans ? explain.
Answer:
yes its important because...
Explanation:
Water is an essential feature of homeostasis in an organism. Water increases the volume of blood, which affects blood pressure and heart rate. Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide. Water can be excreted, so it carries toxins that have been made water-soluble out of the body.

Natural selection disrupts the _______ because one allele of a gene is preferred over another, changing the allele frequencies over time.
genetic drift
Explanation:
Genetic drift is changes in allele frequencies of a gene pool due to chance or random events. This can occur in large or small populations. Genetic drift causes gene pools of two isolated populations to become dissimilar as some alleles are lost and other are fixed.

Why do different colors affect photosynthesis differently
Answer:
Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn't).

At which ocean-floor feature do plates move together?
Answer:
divergent plate boundaries
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

Explain how a moderate
increase in (1) light and (2) carbon dioxide could
affect photosynthesis in a desert plant. Address
both conditions for full credit.
Answer:
1) Moderate increase in light increases the photosynthetic rate
2) Moderate increase in CO2 increases the photosynthetic rate
Explanation:
Photosynthesis is a metabolic process unique to the cells of autotrophic organisms such as green plants. It is the process whereby they synthesize their food in form of sugars (glucose) in the presence of sunlight energy.
The photosynthetic process, although comprises of several reactions and processes, is generally described as the reaction of carbon dioxide, water and light to give glucose and oxygen gas as products. The general equation is as follows:
6CO2 + 6H2O + light → C6H12O6 + 6O2
Since both light (needed to supply energy) and CO2 (carbon source) are reactants of the photosynthetic process, a MODERATE INCREASE in them will INCREASE THE RATE AT WHICH PHOTOSYNTHESIS OCCURS.

The gene frequency for a particular trait in a population was determined to be 80% A (dominant allele) and 20% a (recessive allele). Fifty years later, the gene frequency was determined to be 60% A and 40% a. What does this change most likely indicate about the gene pool?
Answer:
Explanation:
Microevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period.
Population genetics is the field of biology that studies allele frequencies in populations and how they change over time.
Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.
\text{Frequency of allele }AFrequency of allele Astart text, F, r, e, q, u, e, n, c, y, space, o, f, space, a, l, l, e, l, e, space, end text, A ==equals \dfrac{{\text{Number of copies of allele }A \:{\text {in population}}}}{\text{Total number of }{\text{copies of gene in population}}}

The gene pool of a population consists of all the copies of all the genes in that population.
This change in the gene pool most likely indicates the existence of microevolution. It generally includes the implications of various evolutionary forces like migration, genetic drift, mutation, natural selection, etc.
What is Microevolution?Microevolution may be characterized as a series or sequence of changes that may lead to alterations in the frequency of genes. Due to this, the overall gene pool may get influenced within a particular time.
This methodology and the complete process of alteration in the gene pool with respect to the evolutionary forces are studied under population genetics. It is the field of biology that significantly involves the detailed study of alleles and their frequencies among populations.
According to the context of this question, the gene frequency for a particular trait in a population was determined to be 80% A (dominant allele) and 20% a (recessive allele). Fifty years later, the gene frequency was determined to be 60% A and 40% a. This is due to the microevolution.

What is a clue that the lac operon is on?
A.)Lactose is absent.
B.)The cell membrane changes.
C.)The repressor protein has fallen off the molecule.
D.)RNA polymerase is blocked by the repressor.
The correct answer is C.) The repressor protein has fallen off the molecule.
The lac operon is a regulatory system found in bacteria, which controls the expression of genes involved in lactose metabolism.
The lac operon consists of three main components: the structural genes (lacZ, lacY, and lacA), the promoter region, and the operator region. The regulation of the lac operon depends on the presence or absence of lactose and glucose.
In the absence of lactose, the lac repressor protein binds to the operator region of the operon, preventing the expression of the structural genes. This inhibits the production of enzymes involved in lactose metabolism.
However, when lactose is present in the environment, it acts as an inducer. Lactose is converted into allolactose, which binds to the repressor protein and causes it to undergo a conformational change. As a result, the repressor protein falls off the operator, allowing RNA polymerase to bind to the promoter region and transcribe the structural genes.
Therefore, the clue that the lac operon is on is the falling off of the repressor protein from the operator region, enabling gene expression and the production of enzymes required for lactose metabolism. Therefore, the correct answer is C.
