According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (NO2-) and nitrates (NO3-)?
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.

Explanation:
Ophrys sphegodes, the early spider orchid, has flowers with yellow-green sepals and petals and one highly modified, velvety brown central petal at the base of the flower. There is single male anther is found at the tip of the column. The stigma is on the underside of the column just below the anther.
Required:
a. Is the flower complete or incomplete?
b. Is the flower perfect or imperfect?
c. Is the flower radially or bilaterally symmetrical?
Answer and Explanation:
a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.
b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.
c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.

Answer:
Two plant groups you could look at are land-based plants and water-based plants.
Explanation:
Land-based plants:
Land-based plants are plants that can be found on land. They tend to be taller in order to absorb as much sunlight as possible. Land-based plants often have roots that are rooted in soil, and take in water and nutrients from there. Land-based plants taken in oxygen and carbon dioxide directly from the atmospheric air around them. In terms of the location of their stomata, stomata can be found on the underside of leaves, where they take in carbon dioxide and release oxygen.
Water-based plants:
Water-based plants can be found either submerged or floating on water. They tend to be broader instead of taller. For instance, their leaves will be broader in order to absorb maximum sunlight. This is because (especially for completely submerged water plants), light does not penetrate as deeply into water, leaving the plant with less light energy to photosynthesize. Water-based plants often have roots that either dig into the soil if they are found at the ocean floor, or hang freely in the water if they float on water surfaces. Unlike land-based plants, water plants, especially those that are fully submerged, take in dissolved carbon dioxide and oxygen gas in the water instead of from the air and atmosphere. The stomata of water-based plants are often found on the upper side of their leaves, in order to have better access to atmospheric oxygen and carbon dioxide.

A.O. is an 89-year-old woman with a long history of systolic heart failure secondary to a large left ventricular infarct when she was in her 70s. She had poor activity tolerance and required assistance with activities of daily living. Even minimal activity was associated with moderately severe dyspnea and exertional chest pain, which was relieved by rest. A.O. also exhibited marked pedal edema bilaterally. She is being treated with digitalis, furosemide (Lasix), KCl, and sublingual nitroglycerin.
What compensatory mechanisms are likely to be operative in A.O. to enhance cardiac output?
A. Prolonged stretch on the myocardium results in myocardial atrophy.
B. Baroreceptors detect low blood pressure and cardiac output and activate the parasympathetic system resulting in increased heart rate.
C. Renin-angiotensin system activation causes decreased glomerular filtration rate and fluid retention, which results in increased preload.
D. Baroreceptors detect low blood pressure and cardiac output and activate the sympathetic system resulting in decreased heart rate.
Answer:
The correct answer is ''C. Renin-angiotensin system activation causes decreased glomerular filtration rate and fluid retention, which results in increased preload.''
Explanation:
In states of low cardiac output, the renin-angiotensin-aldosterone pathway is activated as a compensatory mechanism, whose objective is to fundamentally modify the peripheral circulation, which operates in conjunction with the activation of the medullary neuro-adrenal system, to maintain blood pressure. These two mechanisms, which are totally different, are closely linked; thus, stimulation of beta-1 adrenoreceptors in the juxtaglomerular apparatus, as a consequence of a high adrenergic output, causes renin output in heart failure. On the other hand, the activation of baroreceptors in the renal vascular bed caused by a reduction in renal blood flow, is also responsible for the release of renin, it occurs in patients with severe heart failure managed with diuretics and salt restriction.

On the planet Feline, there are only cats. For one particular phenotype, Myles, there are two manifestations: either the cats like jazz music (the wild type phenotype) or they do not (the mutant phenotype). Under the assumption this phenotype is determined by a single gene with two alleles, and given that a mating of two wild-type cats produces the following number of offspring: Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123. The mode of inheritance most consistent with these data is:________
A. Autosomal dominant.
B. Two-locus inheritance.
C. Sex-linked recessive.
D. Autosomal recessive.
E. Two-locus dominant.
Answer:
D. Autosomal recessive.
Explanation:
Available data:
One diallelic gene codes for the phenotype MylesOne allele expresses the wild type phenotype → like jazz musicThe other allele expresses the mutated phenotype → don´t like jazzCross: Between two wild catsF1) Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123Autosomal recessive inheritance characterizes because the mutated gene locates in one of the 22 non-sexual, somatic chromosomes. To express the phenotype, an individual must carry two copies of the mutated gene. For this reason, the recessive allele must be present in both the male/father and the female/mother.
In the exposed example, the numbers among the progeny are 341:369:121:123. These values approximate a phenotypic ratio 3:1 for females, and for males. This ratio suggests that the cross was performed between two heterozygous individuals.
Let us name the alleles M and m, dominant and recessive respectively. The cross would be like follows
Cross: wild-type male x wild-type female
Parentals) Mm XY x MmXX
Gametes) MX, MY, mX, mY MX, MX, mX, mX
Punnett Square) MX MX mX mX
MX MMXX MMXX MmXX MmXX
mX MmXX MmXX mmXX mmXX
MY MMXY MMXY MmXY MmXY
mY MmXY MmXY mmXY mmXY
F1) Whole progeny
12/16 = 3/4 = 75% Wild-type cats → MMXX + MmXX + MMXY + MmXY4/16 = 1/4 = 25% Mutated cats → mmXX + mmXYFemales
6/8 = 3/4 = 75% Wild-type cats → MMXX + MmXX 2/8 = 1/4 = 25% Mutated cats → mmXXMales
6/8 = 3/4 = 75% Wild-type cats → MMXY + MmXY2/8 = 1/4 = 25% Mutated cats → mmXY
Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

When H. pylori was first discovered, researchers doubted the finding. It was thought that the acidic environment of the stomach was too hostile for microbes to thrive. Newer research using genetic analysis and culture techniques has revealed that there is a diverse gastric microbiota. Of the options below, what is the only one that does not involve genetic analyses?
A. Sequencing approaches have shown that the normal microbiota includes Archaea and provide mechanisms for studying their distribution.
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
C. Knowledge of the microbiota from sequencing efforts has been used to improve cultivation techniques.
D. Genetic analyses have been used to examine the dominant species in different individuals, showing that it varies from one individual to another.
Answer:
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
Explanation:
Genetic analyzes are tests that try to identify the genetic composition of a living being, being able to analyze the DNA in a profound way and obtaining crucial information about the organism. The most common way to carry out a genetic analysis is through the sequencing of genes, since they are segments of DNA molecules. Therefore, we can conclude that among all the response options presented above, all that refer to the sequencing of genes should be discarded. Thus, we can see that option B is the correct option, since the analysis of growth rates does not involve a genetic analysis.

Four scientists observed an area of land that had been cleared of all trees and bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted?
Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.
