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).

breathing involves the movement of diaphragm and Rib cage



true or false​

Answers

Answer:

True

Explanation:

It's a true statement as,

When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.

Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.

Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!

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.

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.
