I took the test and I got it correct

Answer:

1. Hypotonic

2.Isotonic

3.Hypertonic

Explanation:

Number 1 is hypo tonic because solute is going into the cell. The cell is getting bigger and expanding. You can think of Hypotonic as getting bigger by using Hypo which can be Hippo. Hippos grow bigger over time.

Number 2 is Isotonic. The water is going in and out at the same rate. Therefore, nothing really changes here.

Number 3 is Hypertonic because the cell has shrunk.

Answer:

0.25m/s2

Explanation:

Force = mass x acceleration

5 = 20 x a

a = 5 ÷ 20

= 0.25m/s2

The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.

The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body.  High-density lipoprotein can lower your risk for heart disease and stroke.

Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

Answer:

to be honest i think the answer is the population

Explanation:

Answer:

Populations evolve through a process known as natural selection which allows individuals with beneficial traits for survival to breeding with other individuals who share those traits, eventually leading to offspring who only exhibit those superior traits.

Answer:

Explanation:The deeper you go into the Earth the older the fossils will be. So, in the diagram you have provided we see that fossil #5 is the oldest and fossil #2 is the youngest.

The order of age goes like this (from youngest to oldest):

1. Fossil #2

2. Fossil #1

3. Fossil #4

4. Fossil #3

5. Fossil #5

Therefore, the only correct answer would be that fossil #4 is younger than fossil #3.

The complimentary DNA strand for the sequence ACT GCA is TGA CGT​.

DNA stands for deoxyribonucleic acid which is defined as a polymer made up of two polynucleotide chains which coil around each other to form a double helix.

Primarily DNA is located in the cell nucleus called nuclear DNA, but a small amount of DNA can also be found in mitochondria called mitochondrial DNA or mtDNA, so mitochondria are structures within cells that store energy from food that converts into energy.

The information in DNA is stored in the form of code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T) which are bond to each other by hydrogen bond like A with T with 2 hydrogen bonds while C with G with 3 hydrogen bonds. Like for above given information,  ACT GCA complimentary strand is TGA CGT

Thus, The complimentary DNA strand for the sequence ACT GCA is TGA CGT​.

Explanation:

Sorry if wrong

Answer: The correct statements are 1 and 2:

1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.

2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Explanation:

Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.

There are two types of pollination

--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.

--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
