A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half, what is the volume and d
spayn [35]

Answer:

Volume= 4 cm³

Density= 2 g/cm³

Explanation:

We have the following data:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.  

For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.

A) chordate.

B) echinoderm.

C) nematode.

D) mollusc.

Answer:

A) chordate.

Explanation:

The animals can be distinguished based on embryonic development and are categorized into two types: Deutrostomes and the protostomes.

The deuterostomes are the organism in which the small opening in the embryo called the blastopore develops into the anus. The deuterostomes organism belongs to two groups of the animal: the echinoderms and the chordates.

The chordates are the animals which possess the bilateral symmetry that is can be divided into left and right sides and posses true cavity or coelom.

Thus, Option-A is correct.

amid [387]
The answer to this question would be: <span>producing large quantities of proteins for secretion.
</span>
A cell with many rough endoplasmic reticulum has a high protein synthesis capability. This will make the cell able to produce many proteins like enzyme. One example of this type of cell will be pancreas cells. This cell will need many enzymes to digest food that you eat so it will need many ER to produce it.
