Is a virus a living organism?why?

Answers

Answer:

Hello! How r u?

Explanation:

a virus is a submicroscopic infectious agent that replicates ONLY inside the living cells of an organism. In my opinion I would say no, only because it can duplicate itself once it has become the host of the living organism and make them sick, and will soon be contagious doesn't mean it's an living thing.

recently went to the doctor and it was determined that her kidneys are retaining sodium
causing an increase in blood volume. Use the information provided about this patient to
select the correct blood flow you would expect the patient to have and the correct effect
of that blood flow.
a. High Blood Pressure. Increased Blood Flow
6. High Blood Pressure. Decreased Blood Flow
C Low Blood Pressure increased Blood Flow
Lou Blood Pressure Decreased Blood Flow


Answers

Answer:

b.  High Blood Pressure. Decreased Blood Flow

Explanation:

As per the details, patients's kidney is retaining more sodium causing increase in blood volume which will result into high blood pressure and decrease in blood flow.

This is because excessive salt in the body causes high blood pressure (hypertension) that results into stiff and narrow blood vessels and decreases blood flow to other organs. To overcome the supply of less blood to the organs, the heart pump blood with more intensity that further increases blood pressure.

Hence, the correct option is "b".

B) Energy: cellulose and chitin

Structure: glycogen and starch

C) Energy: chitin and glycogen

Structure: cellulose and starch

D) Energy: cellulose and starch

Structure: chitin and glycogen

The answer is option A

Explanation:

Carbohydrates are biological molecules in living systems. Polysaccharides are a type of carbohydrate molecules, which are polymers made up of monomers called monosaccharides. Monosaccharides such as glucose, fructose etc. are joined together by glycosidic bonds to form this polysaccharides. However, polysaccharides found in nature are classified based on their function in their found organisms.

1) Energy: Glycogen and starch are the two carbohydrate polymers that function in this aspect. They are both made up of long chains of glucose unit linked by α glycosidic bonds. Glycogen stores energy in the animal cells while starch stores energy in plant cells.

2) Structure: Cellulose and Chitin are the two carbohydrate polymers involved in this function. Cellulose is made up of glucose monomer linked together by β glycosidic bonds. It is the major structural component found in the cell wall of plant cells. Chitin is also a polymer of N-acetyl glucosamine and the major structural component of the cell wall of oorganisms like fungi.

Which of the following best describes the circled part of the

Answers

Answer:

4(3/7)

Explanation:

7x+9=40

7x=40-9

x=31/7

x=4(3/7)....

The circled part of the statement, "7x + 9," is the algebraic expression on the left side of the equation. This expression represents the sum of the product of 7 and the variable x and the value 9.

What is a mathematical expression?

The circled part of the statement, "7x + 9," represents the mathematical expression for the left side of the equation. It is composed of two terms: "7x" and "9." The term "7x" is a product of a coefficient, 7, and a variable, x. This means that the value of "7x" changes depending on the value of x. The term "9" is a constant, which means that its value remains the same regardless of the value of x. Together, these two terms make up the left side of the equation and represent the value that we are trying to find by solving the equation.

The right side of the equation, "40," represents the value that we are trying to match the left side to by solving the equation. The equation is then solved by isolating the variable x, which is done by subtracting 9 from both sides of the equation, which results in 7x = 31, then dividing both sides by 7, which results in x = 4.5.

Are viruses considered living?
Are viruses considered a cell?
What does a virus need in order to
replicate/reproduce?
How do viruses look

Answers

Answer:

In order to replicate, viruses must first hijack the reproductive equipment of a host cell, redirecting it to 'photocopy' the genetic code of the virus and seal it inside a newly formed container, known as the capsid. Without a host cell, the virus simply can't replicate.

What does a virus need in order to

replicate/reproduce?

Explanation:

Viruses replicate in four stages:

1. Attachment

During this stage, the virus attaches itself to the host. It may have either spikes or pins to help it attach.

2. Penetration

The virus injects the nucleic acid into the host cell.

3. Transcription

The host cells nucleic acid disintegrates, and the virus assembles the fragments to create its own structure and its own DNA or RNA.

4. Lysis

The host cell is split open to release the newly copied viruses it created in the host cell.

The new copies of the virus then repeat the process in new host cells.

Can anyone give a paragraph answer to what global footprint means! Thank you.

Answers

Answer:

The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy.[2][3][4] It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment.

Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has been using natural capital 1.7 times as fast as Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.7 planet Earths.[1][5]

Ecological footprint analysis is widely used around the world in support of sustainability assessments.[6] It enables people to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations.[2]

Photosynthesis and cellular respiration are the driving forces behind carbon cycle.

What is carbon cycle?

Photosynthesis and cellular respiration are the primary processes responsible for driving the carbon cycle, which is the movement of carbon through the Earth's atmosphere, oceans, and land.

Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using energy from sunlight. This process removes carbon dioxide from the atmosphere and stores it in the form of glucose, which is used by plants for growth and energy.

Cellular respiration is the process by which cells convert glucose and oxygen into energy, releasing carbon dioxide and water as waste products. This process occurs in all living organisms and is the reverse of photosynthesis.

The carbon cycle is also influenced by other processes such as the decomposition of organic matter, the burning of fossil fuels, and the release of carbon dioxide from volcanoes.

Blood vessels are a part of the components that make up the circulatory system. They function to convey blood from one location to the other.

There are three types of blood vessels namely: veins, arteries and capillaries.

Veins: Veins are vessels that convey deoxygenated blood back to the heart (except pulmonary veins). Veins are characterized by the possession of valves that help prevent the backward flow of blood.

Arteries: Arteries are vessels that carry oxygenated blood away from the heart.

Capillaries: Capillaries are tiny vessels that connect arteries and veins.

The base composition of a double-stranded DNA molecule is 26% adenine. What percentage of this molecule is the base guanine? Give only the answer in numerical form so that Moodle will grade your answer correctly. Do not write "%".

Answers

Answer:

26

Explanation:

According to Chargaff's rule, a typical DNA molecule must have an equal ratio of both purine and pyrimidine bases. Purine is made up of Adenine and Guanine bases while pyrimidine is made up of Thymine and Cytosine bases.

Hence, if the amount of Adenine in DNA is 26%, the amount of Guanine would also be 26%. This would leave the remaining 48% of the DNA as Thymine and Cytosine to be shared in an equal proportion of 24% each.

In summary:

If Adenine = 26, Guanine would also be = 26

Adenine + Guanine = 52%

Thymine + Cytosine = 48%
