Imagine the CCA added to the 3' end of the tRNA consisted of DNA nucleotides. It (WOULD/WOULD NOT) be possible to connect an amino acid to this tRNA. Explain.

Answers

Answer:

The correct answer is - it would because both DNA and RNA have 3' OH.

Explanation:

Ammino acid will connect to the tRNA due to the fact that the process of aminoacylation of tRNA when DNA nucleotide is used will perform or act same the mechanism of Class II aminoacyl tRNA synthetase as both DNA and tRNA have 3'OH. This will get the help of  3'OH in the CCA to bond with charged amino acid.

Thus, the correct answer would be - it would because both DNA and RNA have 3' OH.

How much stronger is a magnitude 8 earthquake than a magnitude 5 earthquake?

A. 1000
B. 30
C. 3
D. 10

Answers

Answer:

A. 1000

Explanation:

The Richter scale is a scale of numbers used to measure the magnitude of an earthquake, which is based on the size of its seismic waves. This scale indicates a number to quantify the total seismic energy released by an​ earthquake. The Richter magnitude scale is a base-10 logarithmic scale, thereby a difference of one (1) point in the scale of magnitude corresponds to a 10-fold increase in amplitude. For example, based on the Richter scale, a magnitude-8 earthquake is 100 times greater than a magnitude-6 and 1000 times greater in amplitude than a magnitude-5.

3. Which organs are responsible for
protecting the body? How?

Answers

Answer:

Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel)

Explanation:

hope this helps

Bone marrow is a sponge-like tissue found inside the bones. That is where most immune system cells are produced and then also multiply. These cells move to other organs and tissues through the blood. At birth, many bones contain red bone marrow, which actively creates immune system cells. Over the course of our life, more and more red bone marrow turns into fatty tissue. In adulthood, only a few of our bones still contain red bone marrow, including the ribs, breastbone and the pelvis.

The thymus is located behind the breastbone above the heart. This gland-like organ reaches full maturity only in children, and is then slowly transformed to fatty tissue. Special types of immune system cells called thymus cell lymphocytes (T cells) mature in the thymus. Among other tasks, these cells coordinate the processes of the innate and adaptive immune systems. T cells move through the body and constantly monitor the surfaces of all cells for changes.

Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood. Swollen or painful lymph nodes are a sign that the immune system is active, for example to fight an infection.

The bowel plays a central role in defending the body against germs: More than half of all the body's cells that produce antibodies are found in the bowel wall, especially in the last part of the small bowel and in the appendix. These cells detect foreign substances, and then mark and destroy them. They also save information about the substances in order to be able to react more quickly the next time. The large bowel also contains harmless bacteria called gastrointestinal or gut flora. Healthy gut flora make it difficult for germs to spread and enter the body.

Mucous membranes support the immune system in other parts of the body, too, such as the respiratory and urinary tracts, and the lining of the vagina. The immune system cells are directly beneath the mucous membranes, where they prevent bacteria and viruses from attaching.

The tonsils are also part of the immune system. Because of their location at the throat and palate, they can stop germs entering the body through the mouth or the nose. The tonsils also contain a lot of white blood cells, which are responsible for killing germs. There are different types of tonsils: palatine tonsils, adenoids and the lingual tonsil. All of these tonsillar structures together are sometimes called Waldeyer's ring since they form a ring around the opening to the throat from the mouth and nose.

There is also lymphatic tissue on the side of the throat, which can perform the functions of the palatine tonsils if they are removed.

The spleen is located in the left upper abdomen, beneath the diaphragm, and is responsible for different kinds of jobs:

It stores various immune system cells. When needed, they move through the blood to other organs. Scavenger cells (phagocytes) in the spleen act as a filter for germs that get into the bloodstream.
It breaks down red blood cells (erythrocytes).
It stores and breaks down platelets (thrombocytes), which are responsible for the clotting of blood, among other things.
There is always a lot of blood flowing through the spleen tissue. At the same time this tissue is very soft. In the event of severe injury, for example in an accident, the spleen may rupture easily. Surgery is then usually necessary because otherwise there is a danger of bleeding to death. If the spleen needs to be removed completely, other immune system organs can carry out its roles.

What is a way to prevent eutrophication?

Answers

Answer:

Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

The following is a list of methods that can be used to control eutrophication:

planting vegetation along streambeds to slow erosion and absorb nutrients.

controlling application amount and timing of fertilizer.

controlling runoff from feedlots.

The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.

B. Loosely dispersed DNA and proteins.

C. Tightly wound DNA and proteins.

D. Loosely dispersed DNA.

Answers

I think C, but I’m not sure.

Answer:

C

Explanation:

So, there are 2 different forms that DNA can be found in.

The more common form, where the DNA is loosly scattered.

There is a less common form, however, only found during cell division, which is a compacted form. The DNA is tighly wound in this case.

In the case of chromosomes, DNA is tightly pakced, and not loose.

Now, do they are do they  not have protiens?

Well, heres another question, how does the DNA get compacted?

It has to wrap around histone protiens.

The logn strands of DNA wrap around many histone protiens, until the full length of DNA has been compacted.

So to answer the question, yes, there are protiens found in chromosomes(specificly histone).

This means the answer must be C, since chrosomes are both tightly bound, and contain protein.

Fat cells are expandable. How does this structure relate to a fat cell's function?

A) Fat cells store energy for the body to use later, so being
expandable would help with storage.

B) Fat cells burn energy quickly when other food source is available, so being expandable would help with the rapid burn.

C) Fall cells protect organs, so being expandable can help with cushioning.

D) Fat cells do not expand

Answers

Fat cells burn energy quickly when other food source is available, so being expandable would help with the rapid burn.

The relationship between the expandability of fat cells and a fat cell's function is ; ( A )  Fat cells store energy for the body to use later, so being expandable would help with storage.

Fat cells specialized for the storage of energy in human body is the Adipose tissue which can expand between 60 to 70% of the weight of the human body in response to changes in the energy balance of the body.

Adipose tissues store energy in form of triglycerides and in order to store more energy for later use the Adipose would need to be expandable to accommodate the required amount of energy.

Hence we can conclude that the relationship between the expandability of fat cells and a fat cells' function is Fat cells store energy for the body to use later, so being expandable would help with storage.

Explanation:

Volume can be measured in both liters (L) and cubic centimeters (cm³), however,

1 liter = 1000cm³

According to this question, a partly full paint has 2.75 liters of paint left in it.

Since 1 liter = 1000cm³

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. Initially, the concentration of the drug in the bloodstream is C0 g/mL. What is the concentration of the drug in the bloodstream any time t

Answers

Answer:

[tex]C(t) = C_oe^{-kt}[/tex]

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

[tex]\dfrac{dC}{dt}[/tex] decrease proportionally to Concentration C

i.e

[tex]\dfrac{dc}{dt} \alpha - C[/tex]

[tex]\dfrac{dc}{dt} = -k C[/tex]

[tex]\dfrac{dc}{c} = -k dt[/tex]

[tex]\int \dfrac{dc}{c} = -k \int dt[/tex]

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C)  - ㏑C₀ =  -kt

[tex]\dfrac{C}{C_o} = e^{-kt}[/tex]

[tex]C(t) = C_oe^{-kt}[/tex]

The concentration of drug in blood at any time t is:

[tex]C(t) = C_oe^{-kt}[/tex]
