Answer:

Bacteria

Explanation:

Bacteria reproduce most quickly .  Fruit flies can go from the egg to sexual maturity in 3 weeks while bacteria can reproduce once they are "born" and can do so multiple times a day, while fruit flies can reproduce if mature once every day about.  

Finches and humans obviously have much slower rates of reproduction.

Answer:

A. Inferior

-Medial: towards the midline of the body

Upon googling a picture for the diaphragm and lungs, you will see that the diaphragm is a muscle situated directly below the lungs. The phrase "located in relation to" is asking you specifically "when compared to". Therefore, since the diaphragm is located below the lungs, the answer would be inferior.

I hope this answer and explanation helped you understand this topic a little bit more!

The diaphragm is located in inferior to lungs.

In mammals, the diaphragm is a dome-shaped, muscular and membrane tissue that divides the thoracic and abdominal compartments.

It is the primary respiratory muscle.

The diaphragm gets contract and flatten up during we inhale, while the chest cavity expands.

Vacuum is created due to contraction, which pulls air into the lungs.

Exhalation relaxes the diaphragm and causes it to return to its domelike shape, pushing air out of the lungs.

So we can conclude that the diaphragm is the muscle that connects the chest cavity to the abdomen and it is the primary respiratory muscle, when one breathes in, the diaphragm muscle contracts, causing the lungs to expand and vice versa, and most importantly it located inferior to lungs.

Answer:

If thick-shelled snails have thick-shelled offspring and thin-shelled snails have thin-shelled offspring then this is good evidence that shell thickness is heritable.

Explanation:

Inheritance is a natural mechanism by which genetic information contained in the DNA sequence is passed from parents to offspring. Moreover, heritability is a measure of the genetic influence on the variation in a particular phenotypic trait (e.g., height, eye color, etc.) between individuals in a population. The values of heritability for a particular phenotypic trait range from zero (when all variation in a population comes from environmental factors and therefore is not heritable) to one (when all variation in a population comes from genetic factors and therefore is heritable). For example, in this case, if parental snails always have offspring with the same phenotype for the trait ‘shell thickness’, it would indicate that the heritability for this trait is equal to one, thereby evidencing that all of the variability for the trait 'shell thickness' comes from genetic differences.

Answer:

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

have a good day :)

Explanation:

Answer:

The primary functions of RNA are as follows:

Facilitate the translation of DNA into proteins

Functions as an adapter molecule in protein synthesis

Serves as a messenger between the DNA and the ribosomes.

They are the carrier of genetic information in all living cells

Promotes the ribosomes to choose the right amino acid which is required in building up of new proteins in the body.

Answer:

During meiosis , four daugther cells are produced

Answer:

4 cells. You end up with four cells.

Explanation:

Each daughter cell undergoes meiosis-II, producing two cells. In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell.

Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.

Answer:

A

Explanation:

Answer:

78 chromosomes

Explanation:

Since the number of chromosomes in a dog are diploid, we have 2n chromosomes where n = number of chromosome pairs.

Since n = 39.

The number of chromosomes is 2n = 2 × 39 = 78 chromosomes

So, a dog has 78 chromosomes.

High Altitude Living Quick Check

Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.

Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.

Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.

Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

Answer:

if a person has 45 chromosomes they will get down syndrome

Explanation:

In the trp operon, tryptophan acts as a corepressor, binding to the repressor and inducing it to stop to attachment of RNA polymerase. Therefore, option D is correct.

The trp operon is a group of genes in bacteria that are involved in the biosynthesis of the amino acid tryptophan. The operon is composed of five structural genes, trpE, trpD, trpC, trpB, and trpA. These genes code for the enzymes involved in tryptophan biosynthesis.

In the trp operon, the presence of tryptophan serves as a corepressor. The tryptophan molecule binds to the trp repressor protein, causing a conformational change that allows it to bind to the operator region of the operon.

This blocks the attachment of RNA polymerase to the promoter, preventing transcription of the genes involved in tryptophan biosynthesis. Thus, option D is correct.

Answer:

Alternation of generations is a type of life cycle by which species alternate haploid (n) and diploid (2n) individuals.

Explanation:

Alternation of generations refers to the life cycle observed in terrestrial plants by which species alternate between haploid (i.e., organisms having a single set of chromosomes) and diploid (2n, i.e., organisms having a single set of chromosomes) generations. Plants alternate between a sporophytic stage and a haploid gametophytic stage. This alternation of generations is accompanied by the alternation between sexual reproduction, where the fusion of male and female gametes from the gametophyte generation produces a diploid zygote that develops into the sporophyte, and asexual reproduction, where spores (generated in the sporangium of the diploid sporophyte) are released and germinate into new individuals.

Answer:

I think no 3 will be the answer.

In cell one amino acid can bind with two or three different tRNA during protein synthesis in the translation process, hence 3 option is correct more than 20 molecules are found.

Because they can read nucleic acid words (like mRNA codons) and transmit the relevant messages, tRNA molecules serve as translators of amino acids. for each of the 20 amino acids.

There is a tRNA some amino acids bind to 2 or 3 different tRNAs, so cells may contain as many as 32 different tRNAs. Possibility of more than one tRNA and more than one anticodon for an amino acid, there is often only one aminoacyl tRNA synthetase for each amino acid.

Enzymes known as transfer RNA (tRNA) synthetases are responsible for joining a particular amino acid to its associated tRNA in order to produce proteins at the ribosome.

Therefore one amino acid can bind with two different tRNA in a cell during translation, hence option 3 is correct.

Answer:

The correct answer is c. an efficient system for conducting water and minerals.

Explanation:

Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.

Answer:

So, heating a magnet disrupts the domain walls and it becomes easy for the magnetic domains, which are ordinarily lined up, to rotate and become misaligned. They are now less aligned and point in the opposite direction to their neighbors, causing a decrease in the magnetic field and loss of magnetism.
