The michaelis constant (km) is analogous to _______ that an enzyme has for its substrate. if the km drops then the enzyme has (gained / lost) affinity and if the km increases then the enzyme has (gained / gained) affinity.

Answers

Answer 1
Answer: The Michaelis menten constant (Km)

Is analogous to the affinity or the compatibility the particular enzyme has for its given substrate.

If the km drops, then the enzyme has reduced or lost affinity and likewise an increase in the affinity or gain is based on an increase in the value for km.

which of the following statements provided the evidence for you to rule out the possibility that morgan had lyme disease or flu?

Answers

Answer: Morgan did not have a sore throat, fever, or swollen lymph nodes

Explanation:

Signs of these diseases usually are the same for everyone:

Flu is one of the most common diseases to occur in the present time. Typically, the fall season is when flu starts to hit in the year. Headaches, fevers, sore throat, fatigue, runny nose and a slightly flushed face are often symptoms of the disease. Those are symptoms of other diseases too, but they're most related with the flu. As you can see, sore throats are fevers are probably the most notable signs and Morgan didn't have either.

Lyme disease has most of the above symptoms, along with muscle stiffness, rashes and swollen lymph nodes. On the left and right side of your neck there are your lymph glands. They're part of your immune system and filter the unknown substances that go through your face. Typically, you can hardly feel them, but if they pop out and you can see them in clarity, it may mean you have cancer or Lyme disease, and if untreated can cause permanent damage or even death. Therefore, seeing that his lymph nodes are normal, Morgan didn't have Lyme disease either.

Hope that helped a lot. Let me know any further questions.

In pea plants purple flowers are dominant to white flowers. If two white flowered plants are cross, what percentage of their
offspring will be white flowered?

Answers

Answer:

100%

Explanation:

This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.

According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).

Therefore, 100% of the offsprings will be white flowered.

What is the layer of myelin that surrounds an axon called?Group of answer choices

1. Node of Ranvier
2. Perichondrium
3. Perimysium
4. Myelin sheath
5. Periosteum

Answers

The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.

I think the answer is Nodes of Ranvier but I’m not sure. I hope this helped <3

These structures protect and enclose gene expression products as they move from the site of protein synthesis to its final secretion from the cell. ___________

Answers

Answer:

The correct answer will be- Cargo vesicles

Explanation:

The product of the gene expression is known as the protein which is formed as the result of the transcription and translation.

The process of translation takes place in the ribosomes attached to the endoplasmic reticulum after which the proteins enter the lumen of the endoplasmic reticulum.

The protein then enters the secretory pathway which represents the movement of proteins by packaging them in cargo vesicles attached with the cargo proteins.

Thus, Cargo vesicles are the correct answer.

what is viscosity and what effect does heat have on the viscosity of DNA? What is the underlying cause of the change?​

Answers

Answer:

Please find the definition of viscosity, effect of heat on DNA explanation to this question below

Explanation:

Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.

DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.

Final answer:

Viscosity refers to the 'thickness' or 'stickiness' of a fluid. Heat decreases the viscosity of DNA by providing energy to the molecules, which reduces the 'stickiness' between them. The underlying cause is changes in the interactions between the DNA molecules due to the heat energy overcoming the forces holding them together.

Explanation:

Viscosity is a property of a fluid that resists the force tending to cause the fluid to flow. In simple terms, it is the 'thickness' or 'stickiness' of a fluid. The greater the viscosity, the slower the fluid flows.

When exposed to heat, the viscosity of DNA decreases - it 'thins' and flows more easily. This happens because heat provides energy to the DNA molecules, increasing their movement and reducing the 'stickiness' between them.

The underlying cause of the change in viscosity due to heat is actually due to a change in the interactions between the DNA molecules. The added heat energy overcomes the forces holding the molecules close together, allowing them to move more freely relative to each other, thus decreasing the viscosity.
