Answer:

b. make the proteins coded for in the DNA

Explanation:

Transcription and translation take the information in DNA and use it to produce proteins.

Answer:h

Explanation:

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.

Answer:

Cretaceous

Explanation:

They began changing the way the world looked almost as soon as they appeared on Earth about 130 million years ago, during the Cretaceous period. That's relatively recent in geologic time: If all Earth's history were compressed into an hour, flowering plants would exist for only the last 90 seconds

Answer:

0.25m/s2

Explanation:

Force = mass x acceleration

5 = 20 x a

a = 5 ÷ 20

= 0.25m/s2

Answer:TAG-CAG-GGT

Explanation:I just took the test and got it right

Answer:

non-specific immune cell is an immune cell (such as a macrophage, neutrophil, or dendritic cell) that responds to many antigens, not just one antigen. Non-specific immune cells function in the first line of defense against infection or injury.

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:

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.

It occurs when a chromosome breaks and some genetic material is lost.

Answer:

A

Explanation:

FOOD IS CHEMICAL, KINETIC IS ENERGY SO its A

Answer:

mosses and ferns plants are two types of primitive plants both plants are non flowering plants

Explanation:

therefore both of them are seedless plant as well both moss and ferns under grow Alternatives of generations

Answer:

Hydrogen bond

Explanation: Pretty much just a type chemical bond

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​.

#SPJ2

Answer:

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.

I hope this works and I helped :3

Explanation:

Answer:

Explanation:

All life can be classified into three domains: Bacteria, Archaea, and Eukarya

Organisms in the domain Eukarya keep their genetic material in a nucleus and include the plants, animals, fungi, and protists.

Answer:

A bioevent or bio-event (a shortening of 'biotic event' or 'biological event') is an event recognised in a sequence of sedimentary rocks, where there is a significant change in the biota as recorded by assemblages of fossils over a relatively short period of time.

Explanation:

1.According to Greek legend the war between the Greeks and the people of Troy was a long and bloody one.  And at the center was Helen, the most beautiful woman in all of Greece. And Paris, the Trojan prince who loved her.  PLZ HELP ME THIS IS A GRADE!!  

Answer:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction
