The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.

<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.

You can try the experience at home, by using an object that has a lower density than the water like the sunflower oil, you will see that it will stay at the top of the water too.

The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well
spayn [35]

Answer:

PFK (protein): cytoplasm only (targeting pathway)

Insulin (protein): ER->Golgi->outside cell

Explanation:

Translation can be described as the mechanism by which a protein is produced through a mRNA.

If a particular protein is to function inside the same cell, then it doesn't need to get any modification so that it can travel outside the cell. Such type of proteins are translated on free cytoplasmic ribosomes and are released directly into the cytoplasm to perform their function. For example, PFK protein.

If a protein has to function outside the cell where it is produced, then it has to be modified. Such type or proteins are translated on the rough ER.  They are then modified in the Golgi complex and then transported outside the cell to the area where they have to function. For example, insulin.

In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour.
liraira [26]

Answer:

Natural selection will select the type of ostriches that can run up to 40 mph.

Explanation:

According to the theory of natural selection, organisms with favorable traits following their environment are more likely to reproduce. In doing so, they pass on the better traits to their next generation for the survival of their species.

This process allows organisms to adapt to their environment. And the survival of species is assured.

Here, the type of ostriches that run slow probably fall prey to the jackals. To maintain survival, the ostriches reproduce and lay eggs. If out of almost a dozen eggs, one or two are left to hatch than the <em><u>chances of their survival</u></em> will greatly be affected if the hatching ostriches are of the <em>slow-running type</em>.

Therefore, natural selection may stay in favor of <em>fast-running ostriches</em> to hatch.

zheka24 [161]

An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.

<h3>Variation of ecological habitats within a species is characteristic of which type of diversity?</h3>

The variation of ecological habitats within a specie is character of the type of diversity is known as Ecosystem Diversity.

Ecosystem is defined as the different kinds of habitats, ecological processes and communities. A biological community is defined by the specie which occupy a specific area and the interactions between the species.

So we can conclude that: An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.
