Help is this the correct answer

Answer:

Part A

The scientists threw away their instructions. They should have kept their instructions to properly and safely follow all procedures. Following instructions also ensures useful experimental results.

Part B

The scientist is not wearing safety goggles. He should wear goggles during activities that can harm his eyes. Working safely to avoid injury is every scientist’s job.

Part C

The lab area is messy and needs better organization. The scientist should carefully store the test tubes that aren’t being used. A clean work area helps scientists work safely and efficiently to avoid costly accidents.

Part D

The scientist is disposing of dangerous materials incorrectly. He should have followed disposal instructions as described in the lab procedure. Improper disposal can pollute the environment, harm fragile wildlife, and damage facilities. Scientists must be environmentally responsible.

Part E

The scientist didn’t clean up after an accident. He should have disposed of the glass immediately after it broke rather than waiting. Accidents create hazards for scientists and those around them.

Part F

Scientists should not eat or drink in a lab area. They could swallow something harmful or foul. Snacks and meals should be eaten during designated breaks and never near the lab area.

the father can contribute an X or Y to the baby

Answer:

All of the above.

Explanation:

All the given options are the potential disadvantage of an enzyme that have a very high affinity for its substrate.

The enzyme can be distorted spatially and thus reduces the ability to catalyze the reaction of the active site.

The tight binding of an enzyme to a substrate results in enzyme transition state complex which is higher in energy.

The tight binding also pulls the substrate out of the solution and decreases a driving force in the forward reaction.

Answer: The mass decreases

Answer:

Explanation:  

Huntington´s disease is Autosomal and Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease.

Let us name the dominant allele D and the recessive allele d.

Man´s father → Huntington's disease → Dd

Man´s mother → Normal → dd

Man´s sister → Normal → dd        

The mother of the child is unaffected → dd

If the sister is normal, dd, means that the father is heterozygous for the trait. The sister inherited a recessive allele from her mother and the other recessive allele must have been inherited from the father, who expresses the disease.  

The man has 1/2 of the chances of having the dominant allele because his mother could only pass a recessive allele (100%), and his father could pass either a recessive (50%) or a dominant allele (50%).

If the man inherited the dominant allele from his father, he is heterozygous for the trait, and he has 1/2 of the probability of providing a D allele to the child. The man´s wife is normal, dd, so she can only provide a recessive allele to the child.

There is a good effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter because there is more food available for the blackcap bird which automatically increase the population of the bird. Food is the main factor that contributes in the increase or decrease population of blackcap in the United Kingdom and prevent the removal of this bird in that environment.

Answer:

Because if the food doesn't get texted there is a chance the food might have some things that can spread
