The photic zone has the most nutrients closer to land, an area with sufficient light for photosynthesis, has an abundance of photosynthetic organisms, and is very shallow, Thus, the correct option for this question is E, i.e. all of the following.

The photic zone present in the surface layer of the aquatic ecosystem significantly receives sunlight for photosynthesis. It is the topmost layer that receives sunlight. Hence, this zone is also known as the Sunlight zone.

According to the question, due to the sufficient availability of sunlight, this area performs a good rate of photosynthesis and occupies an abundance of photosynthetic organisms. Phytoplanktons are the characteristic members of this region. As this region has sufficient availability of light, the concentration of nutrients is highly rich.

Therefore,  according to the photic zone, the correct option for this question is E, i.e. all of the following.

Answer:

Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.

Answer:

The correct answer is - Gene 1 and 14.5 (or 14).

Explanation:

The cycle threshold is denoted as Ct value. It is the cross point at the threshold line meets with fluorescence signal reaction curve. In the given RTpcr experiment, the threshold line is fluorescence intensity 1 thus, Ct value for each gene will be the point at which each curve meets the fluorescence intensity line at 1. Ct value of is inversely proportional to amount of nucleic acid in the given sample.

Here, the Ct for gene 1 is the lowest, so the amount of DNA would be highest.

Gene with highest expression= Gene 1

Ct value= 14.5

Fungi show symbiotic association with algae and plants. With plants, they thrive as endophytes in a form of the symbiotic association. This symbiotic association results in the emergence of novel characteristics in the world of biology.  

The lichens function as a tool in finding the quality of air, as they grow in the environment containing good air quality. The tolerance towards heat is another characteristic. Some of the endophytes are witnessed in the plants, which grow in very hot conditions.  

At such conditions, no fungi or plant can thrive, however, in the symbiotic association, they possess the tendency to thrive. If one tries to separate them, it results in the death of both.

Explanation:

So many species on the Earth have gone extinct throughout it's years. Many species have died out over the 4.543 billion years that the earth has existed, and new species are introduced throughout the decades whilst some fade out.

Variation in biology is best delineate because the variations between people of a species, and between completely different species.

Variation refers to the variations or deviations from the recognized norm or commonplace. it's going to be a modification in structure, type or operate in associate degree organism, deviating from alternative organisms of identical species or cluster.

In genetic science, variation refers to a personal that possesses characteristics completely different from the others of identical kind. Genetic variation sometimes arises as a mutation sequence that encodes a super molecule or an polymer.

Variations is also mirrored within the composition of the individual, e.g. a distinction in size, color or pattern, or is also detectable solely by deoxyribonucleic acid or super molecule sequencing.

A given variant is also the results of changes during a single sequence, or the consequence of interactions among multiple genes. Populations of identical species living in several components of the globe is also characterized by specific sets of variations.

Variation will, therefore, be measured at the individual level, i.e. variations between individual individuals during a family or population, or at the population level, i.e. variations between populations living in several regions.

The different kinds of variations are:

Environmental factors - Composition variation known as environmental variation.

Inherited factors- The variation passed on from oldsters to offspring, via genes, throughout copy is named heritable variation.

A species is that the basic unit of classification associate degreed a assortment rank of an organism, furthermore as a unit of variety.

A species is outlined because the largest cluster of organisms within which any 2 people of the suitable sexes or sex activity sorts will turn out fertile offspring, usually by amphimixis.

Other ways in which of shaping species embody

- makeup,

- desoxyribonucleic acid sequence,

- Morphology,

- Behavior or condition.

In addition, paleontologists use the idea of the chrono species since fossil copy can not be examined

Answer:

A. transmission electron microscope.

Answer:

option (D) is the right answer

The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna

For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed

QUESTION 1

According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.

According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:

3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)

2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:

Answer:

a. water pollution policy

Answer:

A

Explanation:

I believe the answer is A because Ventricular Fibrillation means the heart is beating irregularrly, and too fast. Sometimes up to 500bpm

There is no coordinated contraction of the heart, death is possible in minutes. Therefore option B is correct.

Ventricular fibrillation (VF) is a life-threatening cardiac arrhythmia characterized by chaotic electrical activity in the ventricles, the heart's lower chambers.

During VF, the heart loses its ability to pump blood effectively, leading to a lack of blood flow to vital organs.

Without immediate intervention, such as defibrillation to restore a normal heart rhythm, the condition can rapidly progress to cardiac arrest and cause death within minutes.

Unlike tachycardia (A) or bradycardia (D), which involve abnormal heart rates, VF is a more severe and critical situation with disorganized electrical signals and ineffective pumping, requiring urgent medical attention.

Therefore option B There is no coordinated contraction of the heart, death is possible in minutes. is correct.
