Viruses are not alive. Although they sort of “hack” a host’s cells and reproduce, they do not breathe or move on their own. A virus will sit on a counter forever if it’s untouched. Viruses are spread by physical contact, not because they can move around on their own.
Although viruses can attack and hack, and use your cells to reproduce, they are programmed to do so.
Cells are very much alive, while viruses are not.

Indeterminate cleavage results in identical cells capable of forming an embryo while determinate cells do not result in cells which are capable to develop embryo.

Indeterminate is superior to determinate cleavage.

Explanation:

Cleavage is the division of cells in the early embryonic stage. The two stages of cleavage described here are:

In indeterminate cleavage or regulative cleavage occurs when an embryo divides, each cell is capable of developing into complete embryo. eg: Deuterosomes

In determinate cleavage the resulting embryonic cells of blastomere cannot develop into embryos. It is also called as mosaic cleavage. The essential part of the cell might be missing which does not let the cell survive. eg: Protosomes

Indeterminate cleavage is of great importance as the cell grows and can produce new organism. The complete identical twin is formed. Its application can be seen in tomato plants.

3. All animals do not display intermediate cleavage because growth from intermediate cleavage is continuous and does not stop after adulthood which is not possible in animals.

Cadaver Decomposition Island

-  When a body is buried directly in the soil, then it is subject to decomposition by insects and microorganisms. 

<span>- </span>During this process, a self-digestion of the cells occurs as well as anaerobic decomposition of animal proteins resulting in a release of various chemical components.

<span>- </span>This nutrient-rich fluid is trapped in the soil matrix for a long period of time resulting in the formation of Cadaver Decomposition Island

<span>- The formation of Cadaver Decomposition Island is associated with increased microbial biomass and activity.</span>

This procedure is called a vacuum extraction or vacuum assisted delivery. In vacuum assisted delivery, the healthcare practitioner uses a vacuum device with a cup with a handle and a vacuum pump to expedite the delivery of the baby. The vacuum assisted delivery is indicated in mothers undergoing labor for a longer time than normal; with inadequate contractions and failure of cervical dilatation to progress.

How does the decrease of predators and increase of food make the elk population increase? Please explain
damaskus [11]
The decrease of predators would make the elk population thrive, because there would be nothing to hunt them down. And with an increase of food, the elks would have enough to eat therefore the elks would not die from hunger.
