how the structure of a muscle cell is related to its functio​

Answers

Answer 1

Answer:

The structure and shape of each type of human cell depends on what function it will perform in the body. The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.

Answer:

The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.

The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.

Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.

Which of the following statements best compares reproduction in viruses with reproduction in single-celled protists? no links please​

Answers

Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. Therefore, the correct option is (C).

Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. The main difference between reproduction in viruses and single-celled protists lies in their reproductive processes. Viruses are obligate intracellular parasites that lack the cellular machinery required for replication. They rely on infecting host cells and hijacking their machinery to reproduce and create new viral particles. In contrast, single-celled protists are independent organisms capable of self-replication through various mechanisms such as binary fission, budding, or spore formation. They do not need a host cell for their reproductive processes. This fundamental distinction highlights the unique strategies employed by viruses and protists in propagating their species.

Therefore, the correct option is (C).

Answers

Answer:

sister chromatids

Explanation:

Suppose that a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.

What is sister chromatid?

Sister chromatid refers to replicated chromosome that are genetically identical.

Prior to every cell division, a cell must replicate its DNA in order to have an even distribution of genetic material in the daughter cells.

The result of DNA replication is sister chromatids, which carry individual identical DNA.

Therefore, if a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.

if a bacterial cell is capable of taking up foreign dna, it is said to be what?

Answers

Answer:

competent

Explanation:

The uptake of foreign DNA from the environment  is known as transformation

If a bacterial cell is capable of taking up foreign DNA, it is said to be competent.

What is competent?

Transformation is the process by which bacteria can absorb foreign DNA. In DNA cloning, transformation is a crucial step. After restriction digest and ligation, it takes place and transmits freshly created plasmids to bacteria.

Bacteria are chosen on antibiotic plates after transformation. Bacteria are extraordinarily adaptable creatures, with the rare capacity to take in and replicate (or copy) foreign DNA.

They gain an evolutionary advantage from this and are better able to withstand environmental changes. Bacteria, for instance, can acquire DNA that renders them immune to antibiotics.

Therefore, the term is competent for a bacterium that is capable of taking up foreign DNA.
