which picture represents North America in the winter? A B C Or D​

Answer:

Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring.  The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.

C. another identical earth that has not seen increases in greenhouse gases

The best control group for global warming would be another identical earth that has not seen increases in greenhouse gases.

Global warming may be defined as the gradual increase in the Earth's average temperature due to the trapping of greenhouse gases by the atmosphere.

The excessive release of greenhouse gases like methane, Carbon dioxide, nitrous oxide, and ozone are responsible for global warming. These gases are released by automobiles, industrial smoke, etc.

Deforestation is also considered the cause of global warming. Trees help in the reduction of carbon dioxide from the atmosphere and convert it into oxygen.

Therefore, the best control group for global warming would be another identical earth that has not seen increases in greenhouse gases.

Explanation:

DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.

PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

Answer:

Five different forces have influenced human evolution: natural selection, random

genetic drift, mutation, population mating structure, and culture. All evolutionary biologists

agree on the first three of these forces, although there have been disputes at times about the

relative importance of each force. The fourth and fifth forces are new in the sense that they

are not explicated in more traditional texts. This is not an attempt to develop a “new”

theory of human evolution. Instead, the forces of population mating structure and culture

are arbitrary categorizations used to organize several different phenomena of human

evolution. Scientists agree on the phenomena themselves, although they do not always

organize them the same way.

Explanation:

As stated in this question, Semi-conservative model of DNA replication is the acceptable model of replication in which the two synthesized molecules of DNA consists of one new and one old strand each. DNA replication is carried out by an enzyme called DNA polymerase.

In the semi-conservative model, a double stranded DNA separates into two single strands. Each single strand is used as a template for DNA polymerase to synthesize nucleotides based on complementary base pairing i.e. For every Adenine base, Thymine is added and for every Guanine, Cytosine is added and vice versa.

In this question showing an image of a DNA molecule undergoing replication using semiconservative model, the first DNA molecule consists of the following nucleotides on the old strand and its synthesized nucleotides on the new strand:

Old strand - New strand

1. T - A

2. G - C

3. A - T

4. C - G

5. C - G

6. C - G

On the second DNA molecule, we have the following nucleotides on the old strand and its synthesized nucleotides on the new strand.

Old strand - New strand

7. A - T

8. C - G

A. Chromosomes

Explanation:

A Chromosome is some thing carrying genetic information in the form of genes.

We find DNA on the chromosomes, in every living cell that an organism owns. So, the correct option is A.

The word chromosome comes from the Greek words for color (chroma) and body (soma). Chromosomes are so named because they are cell structures, or bodies, that are strongly stained by certain color dyes used in research.

Chromosomes are defined as structures found inside the nucleus of a cell that are organized into genes from proteins and DNA. Each cell normally has 23 pairs of chromosomes.

These are threadlike structures which are made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell.

Therefore, the correct option is A.

Answer:

the answer is a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.

i took the quiz

Medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

Type 1 diabetes also called insulin-dependent or juvenile diabetes which is usually develops in children, adolescents, and young adults, but it can occur at any age. A condition in which the immune system destroys the insulin-producing cells in the pancreas. These are called beta cells.

There are several signs of type 1 Diabetes which include:

When a person suffering from this disease needs medication which is need to act as signaling molecule to activate the signal transduction pathway. Type 1 Diabetes is characterized by a progressive loss of insulin-producing β-cells in the islets of the pancreas. Immune destruction of β-cells is partly mediated by high levels of pro-inflammatory cytokines.

Thus, medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

Answer:

The final volume is the sum of the initial volume and the volume of the object.

Explanation:

Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.

From;

∆V= V2 - V1

V2= ∆V + V1

Hence the answer above

The correct answer is - All plants share a similar life cycle

Explanation:

The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.

The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.
