How are the three international conflicts similar and how are they different?

Answers

Answer:

what's the question? It is not showing anything expect for "How are the three International conflicts similar and how are they different."

private sector international conflict would be a conflict between a U.S. computer company, and a Japanese company which was supplying motherboards for the U.S. company. If the Japanese company had a contract requiring them to ship 10,000 motherboards a month, but they only shipped 6,000, this would cause a private international conflict. It would not be a conflict that involved the U.S. government, but it would be one that would likely be handled in an international tribunal of some sort

Animal use chlorophyll to produce glucose.
True
False

Answers

false
explanation plants do

Animals use chlorophyll to produce glucose. This is a false statement. Hence, the correct answer is second one . Animals are not autotrophs but heterotrophs.

What is photosynthesis?

Photosynthesis is a process in which oxygen and glucose are produced from carbon dioxide and water with the help of sunlight in green plants. This reaction is carried out by the green plant because it consists of chloroplasts.

The chloroplast is the organelle that has chlorophyll pigment, and this pigment is responsible for the photosynthesis process. Due to this, plants are called producers. Animals depend upon the plant for food and are called heterotrophs. Animals cannot do photosynthesis.

In different ecosystems, different producers are present, such as in aquatic ecosystems, where algae and seaweeds perform this function. In terrestrial ecosystems, plants perform this photosynthesis. Consumers feed them depending on the producers, and after both the consumer and the producer die, both are decomposed by decomposers.

Hence, animals use chlorophyll to produce glucose; this is the false statement.

prophase

prometaphase

metaphase

anaphase

telophase

Answer:

A eukaryotic cell goes through a few (4) phases to split into two identical daughter cells.

Explanation:

Prophase, metaphase, anaphase, and telophase are the 4 phases.

1st phase: nuclear envelope disappears and chromosomes become visble

2nd phase: chromosomes line up at the middle of the cell (metaphase plate I believe it’s called), to get ready to divide.

3rd phase: replicated chromosomes split and move to different ends/poles of the cell.

4th phase: 2 nuclei form, including 2 identical daughter cells.

B.nothing, it is random
C.translating into spanish
D.your mother​

Answers

Answer:

A.

Explanation:

A crucial component of controlling transcription is played by proteins known as transcription factors. These crucial proteins aid in identifying the genes that are active in each of your body's cells. Thus, option A is correct.

What is the role of transcription factors?

Proteins called transcription factors control the expression of genes. They affect the transcription process, in which DNA serves as a template to create mRNA, which in turn affects protein synthesis.

Since many transcription factors are either tumor suppressors or oncogenes, cancer is linked to their mutations or abnormal regulation.

It is known that three transcription factor groups play crucial roles in human cancer.

Therefore, transcription factors play a major role in determining which genes are expressed in a cell.

The planet earth being a terrestrial planet is made up of rocks and hard rigid slabs of rocks called plates. These plates float on the flexible (asthenosphere) Mantel.

I understand that earth is a rocks planet and is made up of rocks and these rocks are called plates.

This uppermost layer or the crust of the lithosphere is composed of SIAL that is rocks made from aluminum and silicon, oxygen components. The layer lying below this is made from the semi-fluid matter called as upper mantel that is the asthenosphere which is partly molten and is said as molten rock. Due to the less dynamicity of this layer the above crust floats or drifts.  

Hence the water and soil in the lithosphere are characteristic of the crustal rocks.

Answer:

Strongest acid is hydrochloric acid

Weakest acid is rainwater

Strongest base is sodium hydroxide

Explanation:

pH is defined as the measure of hydrogen ion concentration in a particular solution. pH values seen between 0 and 1 are actually known to be strongest acids. Weakest acids are the ones that move towards neutrality. The neutral pH value is 7.0.

Looking at their pH values, we will discover that hydrochloric acid is the strongest acid. Rainwater is weakest acid because it moves towards neutrality. Sodium hydroxide is the strongest base.

In pH, values between 0-6 are referred to being acidic, 7 is neutral and while 8-14 are basic.

D. The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.

Answers

Answer:

Your answer is B), I took this quiz already.

The statement 'bacteria have been genetically engineered to contain the DNA needed to produce insulin'' BEST explains how bacterial cells are able to produce insulin for humans (Option B).

Recombinant DNA (rDNA) refers to the genetic engineering strategies used to create genetically modified organisms capable of expressing exogenous DNA sequences.

The rDNA technologies involve the use of specific proteins that cut (restriction enzymes) and paste (ligase enzymes) target nucleotide (DNA) sequences in order to design organisms containing such sequences.

The recombinant DNA can be expressed into a suitable vector (in this case, bacteria) in order to produce a protein of interest (e.g., insulin).

In conclusion, the statement 'bacteria have been genetically engineered to contain the DNA needed to produce insulin'' BEST explains how bacterial cells are able to produce insulin for humans (Option B).

Answers

Answer:

A good example may be represented by different shapes and sizes of beaks in finches living on different Galapagos islands

Explanation:

According to the evolutionary theory proposed by Darwin, natural selection is a mechanism that acts on heritable phenotypic variation among individuals within a population. Genetic variation can be considered as the primary source of heritable phenotypic variation. Those organisms that are better adapted for a particular environment will have more chances to survive and reproduce, thereby passing these heritable traits to the next generation. For example, during his work, Darwin observed that the shape and size of beaks in finch species from different islands in the Galapagos archipelago varied as a consequence, i.e., as an adaptation, to the availability of food resources present in each island.

An example of adaptations in other organisms that may have resulted from variations that were favored by natural selection. - The light-colored mice are an adaption favored by natural selection as they were able to live longer.

Adaptations are physical or behavioral traits that make an organism better suited to its environment. The inheritable variation comes from random mutations.

the example of such variations caused by natural selection are:

The Deer mouse adapted to the environment by developing a lighter color.The light-colored mice were able to live longer.

Thus, The light-colored mice are an adaption favored by natural selection as they were able to live longer.

What are T-lymphocytes?

T-lymphocytes, also known as T cells, are a type of white blood cell that plays a key role in the immune system. They are produced in the bone marrow and mature in the thymus gland.

One of the main functions of T-lymphocytes is to assist other lymphocytes, such as B cells, in the immune response. They do this by releasing chemicals that help to activate and coordinate the immune response, and by directly attacking infected cells.

T-lymphocytes also have the ability to kill cells that are infected with a virus or cancerous cells. They do this through a process called cell-mediated immunity, in which they recognize and bind to specific proteins on the surface of infected cells. Once they have bound to the infected cells, they release chemicals that kill the cells, helping to prevent the spread of the infection or cancer.

T-lymphocytes are an important part of the body's immune system and play a vital role in helping to protect the body against infections and disease.
