Answer:

because the moon doesn't line up exactly between the sun and the earth every time it passes.

Explanation:

A solar eclipse can only occur when the Moon is close enough to the ecliptic plane during a new moon. ... Total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth's surface traced by the Moon's full shadow or umbra. An eclipse is a natural phenomenon.

Answer:

the answer is a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.

i took the quiz

Medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

Type 1 diabetes also called insulin-dependent or juvenile diabetes which is usually develops in children, adolescents, and young adults, but it can occur at any age. A condition in which the immune system destroys the insulin-producing cells in the pancreas. These are called beta cells.

There are several signs of type 1 Diabetes which include:

When a person suffering from this disease needs medication which is need to act as signaling molecule to activate the signal transduction pathway. Type 1 Diabetes is characterized by a progressive loss of insulin-producing β-cells in the islets of the pancreas. Immune destruction of β-cells is partly mediated by high levels of pro-inflammatory cytokines.

Thus, medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

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.

Answer:

false

Explanation:

The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.

Answer:

An animal which feeds on dead organic material, especially plant detritus.

Explanation:

Detritivores, are heterotrophs that obtain nutrients by consuming detritus. There are many kinds of invertebrates, vertebrates and plants that carry out coprophagy. By doing so, all these detritivores contribute to decomposition and the nutrient cycles.

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared.  Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally.  This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered.  Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you....!!!!!!

Answer:

The correct answer is - option. b climbing a rope hand over hand is correct

Explanation:

The movement of the kinesin molecules led by the head of one kinesin followed by the second one after another same as one hand moves on the rope at a time and followed by the other hand during climbing the rope.

The movement of the kinesin microfilament is due to the increased affinity by ATP of the head of the kinesin for the microtubule. However, the hydrolysis of ATP decreases its affinity so it slides or moves to the plus end.

Explanation:

A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic

A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.

Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.

They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.

The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.

Therefore, prokaryotes lack a distinct nucleus.
