Answer 1
Answer: natural selection can be best defined as natures natural way of allowing the most adapted specimens to live and reproduce. (so the weaker ones get out competed and die off...)

Hope this helps :D

What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%? O The water would move out of the cell and the cell would decrease in size.

O The salt would move into the cell and the cell would increase in size.

O The salt would move out of the cell and the cell would decrease in size..​

Answers

Answer:

The water would move out of the cell and the cell would decrease in size.

Explanation:

This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.

In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell and the cell would decrease in size.

If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell due to osmosis. The higher external salt concentration draws the water out of the cell, causing the cell to shrink or decrease in size.

We are able to learn all of the following from fossils EXCEPThow living things change over time
bone structure of an organism
the type of hair animals had
the type of teeth an animal had

Answers

you can't learn the type of hair creatures had in fossils as hair is very hard to fossilize because what makes things fossilize is after it gets old enough a layer of hard rock will eventually turn into a fossilized object. anything can fossilize as long as it is physically strong enough to withstand 1,000 years of age.

Isotopes of the same element differ in their ____.number of electrons
number of protons
atomic number
mass number

Answers

Isotopes of the same elements differ in their mass number. Isotopes are those elements have the same protons but differs from their neutrons. That is why it differs in their mass number because the mass number is the sum of protons and neutrons.

Which period of prenatal development is characterized by increased cellular differentiation? Select one:a. Embryonic period
b. Fetal period
c. Preimplantation period
d. Unattached conceptus?

Answers

Answer;

Embryonic period

Explanation;

The germinal stage is the period of gestation from fertilization or conception, when the egg meets the sperm, to implantation of the embryo in the uterus. The embryonic stage of gestation is the period after implantation, during which all of the major organs and structures within the growing mammal are formed.

-Embryonic period begins at fertilization (penetration of the egg by the sperm) and continues until the end of the 10th week of gestation (8th week by embryonic age). The period of two weeks from fertilization is also referred to as the germinal stage.
