Answer:

Explanation:

Acid. is a substance that increases the hydrogen ion concentration in a solution.(hight H+ concentrations) ~When hydrochloric acid is added to water, hydrogen ions dissociate from chloride ions: HCl -> H+ + Cl− ~Addition of an acid makes a solution more acidic.

Which of these is classified as an emerging virus that can have a direct impact on human health?

umka21 [38]

Answer:

The correct answer is: D. Ebola.

Explanation:

Ebola Virus is a single-stranded RNA (ribonucleic acid) virus.
The natural host of the virus is Fruit bat but it can also infect humans.
The transmission of the virus into humans is mediated from infected bats through body fluids.
The major disease caused by the virus is is Hemorrhagic fever. In this disease, the platelet (responsible for clotting of blood) count in the blood drops far below normal. As a result, bleeding can get initiated both in the body interior or exterior. This disease can cause multiple organ failure and death.
Recently, in the year 2018, the Central African country, Democratic Republic of Congo experienced a severely fatal endemic due to the Ebola virus that killed many people within a short period of time.

Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produ

Ivanshal [37]

Answer:

Explanation:

The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms <u>only one strand is used to encode any particular gene</u>.

The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).

Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, <u>which produces an mRNA molecule that has the same sequence as the coding strand of DNA</u>. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.

which sentience explain what happens in the first step of the process shown Quiz: cell nutrition and transport

lianna [129]

The statement which describes what happens in the first step of the process shown in the image quiz above is:

Absorption of light energy by chlorophyll to make carbohydrates.

The correct answer choice is option b.

The complete image quiz is attached.

<h3>How light energy is absorbed in the first stage of photosynthetic nutrition.</h3>

From the image above, it is very clear that there is a capturing of light energy by the green pigment chlorophyll within the chloroplast, this results in production of energy ( glucose ). This process happens in the light reaction stage or light dependent stage of photosynthesis.

However, there are two major types of autotrophic nutrition, these are as follows:

Photosynthetic nutrition
Chemosynthetic nutrition

So therefore, from the explanation above, we can now confirm that the exact thing which happens in the image above explains to us that light energy is absolutely by the plant to make food.

Complete question:

Which sentence explain what happens in the first step of the process shown Quiz: cell nutrition and transport?

a. It involves the synthesis of glucose from carbon dioxide to make carbohydrates

b. Absorption of light energy by chlorophyll

c. A reaction occurred at the stroma which sorrounds the thylakoid membranes of the chloroplast.

d. None of the above.
