Answer:

This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.

Answer:

Lack of mice

Explanation:

If the grasshopper where to go extinct the mice population would decrease. Which would lead to it being harder for snakes to find food or they would begin to rely on a different food source. But the hawks would be able to find less snakes but would overall be fine.

Answer:

False

Explanation:

As stated in this question, Semi-conservative model of DNA replication is the acceptable model of replication in which the two synthesized molecules of DNA consists of one new and one old strand each. DNA replication is carried out by an enzyme called DNA polymerase.

In the semi-conservative model, a double stranded DNA separates into two single strands. Each single strand is used as a template for DNA polymerase to synthesize nucleotides based on complementary base pairing i.e. For every Adenine base, Thymine is added and for every Guanine, Cytosine is added and vice versa.

In this question showing an image of a DNA molecule undergoing replication using semiconservative model, the first DNA molecule consists of the following nucleotides on the old strand and its synthesized nucleotides on the new strand:

Old strand - New strand

1. T - A

2. G - C

3. A - T

4. C - G

5. C - G

6. C - G

On the second DNA molecule, we have the following nucleotides on the old strand and its synthesized nucleotides on the new strand.

Old strand - New strand

7. A - T

8. C - G

9. T - A

10. G - C

answer is mid ocean ridges

Answer:

Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain

Answer:

A. Chromosomes

Explanation:

A Chromosome is some thing carrying genetic information in the form of genes.

We find DNA on the chromosomes, in every living cell that an organism owns. So, the correct option is A.

The word chromosome comes from the Greek words for color (chroma) and body (soma). Chromosomes are so named because they are cell structures, or bodies, that are strongly stained by certain color dyes used in research.

Chromosomes are defined as structures found inside the nucleus of a cell that are organized into genes from proteins and DNA. Each cell normally has 23 pairs of chromosomes.

These are threadlike structures which are made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell.

Therefore, the correct option is A.

Answer:

The final volume is the sum of the initial volume and the volume of the object.

Explanation:

Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.

From;

∆V= V2 - V1

V2= ∆V + V1

Hence the answer above

Answer:

Normally, molecules move naturally down a concentration gradient [From an area of high concentration to an area of low concentration] by a process called diffusion. However, sometimes the concentration of the needed substance is higher in the cell than out of it, so the cell uses a different process called Active Transport. Unlike Diffusion, Active transport requires energy, as it is going against a concentration gradient.

Cells expend energy to move cells across the cell membrane as they use Active transport rather than diffusion.

Answer:

knowledge of the sequence product

Explanation:

A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.

As a result of the double bond in the organic molecule below, we can tell that it is a D. Unsaturated fatty acid.

Unsaturated fatty acids:

Oleic acid has a single double bond which makes it an unsaturated acid. It can be further classified as a monounsaturated acid due to it having just that one double bond.

In conclusion, Oleic acid is an unsaturated fatty acid on account of its double bond.

Answer:

The correct answer is option A. binding of a new molecule of ATP.

Explanation:

Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.

Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.

Answer: they use vesicles for cell transport and they require energy for cell transport

Explanation:

Both endocytosis and exocytosis use vesicles for cell transport, require energy for cell transport. The correct options are a and b.

Endocytosis is the transport of material into the cell, while exocytosis is the transport of material out of the cell.

The distinction can be seen because a vesicle forms around the molecule entering endocytosis. Exocytosis is basically the inverse of endocytosis.

Endocytosis and exocytosis both require energy in the form of adenosine triphosphate (ATP), which is used in the movement of substances into and out of the cell.

Endocytosis is classified into three types: phagocytosis, pinocytosis, and receptor-mediated endocytosis.

Exocytosis is the process by which vesicles fuse with the plasma membrane and release their contents outside of the cell. Exocytosis and endocytosis are both active transport processes.

Thus, the correct options are a and b.
