Answer:

Diffusion does not require energy in any situation.

Explanation:

Diffusion does not require energy because it is a form of passive transport.

The statement that best explains the pattern of inheritance described above is that if the two alleles of an inherited pair differ, then one determines the organism's appearance and is the dominant allele (option C).

Allele is the alternative form of the same gene occupying a given position, or locus, on a chromosome.

According to Gregor Mendel in his law of inheritance, he deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Dominant alleles are alleles that are physically expressed while the recessive alleles are those that are masked by the dominant alleles.

According to this question, Mendel discovered that one parent's trait disappeared in the F1 generation of his experiment, only to reappear in one quarter (¼) of the F2 generation.

This is as a result of the concept of dominance or recessiveness in the allele encoding the particular trait. The dominant allele expressed itself over the recessive one in the F1 generation.

If the puppy is growing out fur, for up to 3 weeks, this is normal, some dog breeds need different coat growth times.

There are supplements to improve the dog's hair and others that guarantee a general improvement for the health of your companion. Vitamin complexes and essential fatty acids are the most common and recommended. Always look for a veterinarian to indicate the best supplement for your case.

With this information, we can conclude that if the puppy is letting its fur grow, for up to 3 weeks, this is normal, some dog breeds need different coat growth times.

D gene is an X-chromosome-linked gene. a) 100% will have the disease, XdY // 0% will be carriers. b) 0% will have the disease // 100% will be carriers, XDXd.

These are genes that can be found only in the X-chromosome. The inheritance pattern expressed by these genes varies from the one expressed by genes located in autosomal chromosomes.

In the exposed exampe,

- muscular dystrophy are X-linked recessive disorders

- woman ⇒ carrier for muscular dystrophy ⇒ heter0zyg0us ⇒ XDXd

- man ⇒ doesn’t have muscular dystrophy ⇒ X-chromosome with the dominant allele ⇒ XDY

- XD ⇒ chromosome rarrying the dominant allele

- Xd ⇒ chromosomes carrying the recessive allele

Answer: I hope this helps you! :3

Explanation:

Step 1: List down the characteristics

Pay attention to the specimens you are trying to identify with your dichotomous key. List down the characteristics that you can notice. For example, say you are trying to classify a group of animals. You may notice that some have feathers whereas others have legs, or some have long tails and others don’t.

Step 2: Organize the characteristics in order

When creating your dichotomous key, you need to start with the most general characteristics first, before moving to the more specific ones. So it helps to have identified the more obvious and less obvious contrasting characteristics among the specimen before creating your dichotomous key.

Step 3: Divide the specimens

You can use statements (i.e. has feathers and no feathers) or questions (does it have feathers?) to divide your specimens into two groups. The first differentiation should be made on the most general characteristic.

Step 4: Divide the specimen even further

Based on the next contrasting characteristic, divide the specimen further. For example, first, you may have grouped your animals as have feathers and have no feathers, in which case the ones with feathers can be categorized as birds while you can further subdivide the ones that have no feathers as having fur and having no fur. Continue to subdivide your specimen by asking enough questions until you have identified and named all of them.  

Step 5:  Draw a dichotomous key diagram

You can either create a text-based dichotomous key or a graphical one where you can even use images of the specimen you are trying to identify. Here you can use a tree diagram or a flowchart as in the examples below.

Step 6: Test it out

Once you have completed your dichotomous key, test it out to see if it works. Focus on the specimen you are trying to identify and go through the questions in your dichotomous tree to see if you get it identified at the end. If you think the questions in your dichotomous key needs to be rearranged, make the necessary adjustments.

Answer:

Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

Answer:

In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP

In other words:

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
