As altitude increases what happens to air pressure

Answers

Pressure decreases due to there being less gas above you

Answer: It decreases

Explanation:

The enzyme could become spatially distorted, thus reducing the ability of the active site to catalyze the reaction. Tight enzyme-substrate binding will reduce the forward rate constant for the reaction. Tight binding of the enzyme to its substrate will pull the substrate out of solution, thus decreasing the driving force for the forward reaction. Tight binding of the enzyme to its substrate will result in the enzyme-transition state complex being higher in energy than with weaker binding. All of the above.

Answers

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.

Without enough iron, our bodies cannot produce enough of a substance in red blood cells that allow them to carry oxygen.

Answers

Answer:

(a). soft substrates

Explanation:

Mobile organisms can be measured by both direct and indirect methods. Direct methods may involve observing the actual behavior (e.g., scoring via timing). Moreover, indirect methods are those where the technique used depends on the species being examined, collecting information such as through recording of tracks in the soft substrate (e.g., mud, sand, snow), presence of fur/feathers, droppings (mammals), etc. For example, indirect observation of insects may involve the determination of exoskeletons, sounds, etc.

How have genetics and heredity contributed to biodiversity on Earth?
1

Answers

Genetics is the very means of biodiversity. Biodiversity literally means the diversity (or variety) of living organisms. Genetics contributes to this through the variety of genes and adaptations that occur to different organisms in order to survive and even thrive in their environment. These adaptations result in different species, subspecies, and, with time, completely new organisms each specialized to live in a specific manner. As an example, cactuses evolved to survive in low water/high temperature environments when normal plants can’t. Without evolution, there would be no plants in the desert as they wouldn’t be able to survive the heat and drought.

I can help the best I can with your science question. what is your question? I will assist you and explain to you in the best way possible!

Explanation:

Please either ask your science question in the comment or make a question on Brainly.

A man and a woman are preparing to have a child. The man finds out that his father has
Huntington's disease. Huntington's disease is an autosomal dominant disorder. The man's
mother does not have Huntington's disease. The man has a sister who does not have
Huntington's disease.
a. Create a pedigree for the family describe. (Be sure to shade individuals affected with
Huntington's disease).
b. List the genotypes on your pedigree.
c. What is the probability that the male has Huntington's disease?
d. If the man has Huntington's disease what is the chance he will pass the disorder to his
child? The mother of the child is unaffected.

Answers

Answer:

Man´s father → Huntington's disease → DdMan´s mother → Normal → ddMan´s sister → Normal → dd        The mother of the child is unaffected → ddMan → Dd → If affected → 50% or 1/2 of probability Man → dd → If not affected Child → Dd → If affected → 50% or 1/2 of probability Child → dd → If not affected

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.

DD or Dd genotypes express the diseasedd genotype expresses the normal phenotype.

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.

Pedigree:

When drawing a pedigree, remember the symbols you need to use

Circles represent femalesSquares represent malesRhombus represents not specified sex (unborn)Full-shaded figures represent affected individualsEmpty figures represent unaffected individuals.  Generations are represented with roman numbersIndividuals can be represented with numbers, genotypes, or names
