Ok this is going to make me work sadly with a time restraints that I have I will be unable to draws the first picture however the rest I can do. 2. vestigial structures are generally parts of an animal's body that is unnecessary and no longer used. specifically whales have vestigial pelvis bones and as you know they dont walk as for my body the appendix is also a good example it kinda just sits there waiting to become infected. 3. embryos from separate organisms in very early stages look VERY alike and can be incredibly difficult to tell them apart from one another. 4. Everyone's favorite dioxy ribonucleic acid or DNA can show ancestry they do this by being similar like my DNA isnt exactly the same as my mothers however there are more then enough similarities in our DNA to tell that we are related. This works for any and all animals as long as they have salvageable DNA so dinosaurs dont count. using DNA we can also tell that I'm more closely related to a dolphin than a shark and I'm more closely related to sharks than sponges. hope I answered what you were looking for thoroughly

List three changes of state during which energy is absorbed.
mote1985 [20]

The three changes of state during which energy is absorbed are:

1. Change from solid to liquid - Melting.

2. Change from liquid to gas - Vaporization

3. Change from solid to gas - Sublimation

All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.

or each of the following genetic topics, indicate whether it focuses on transmission genetics, molecular genetics, genomics or p
Bad White [126]

Answer:

A. transmission genetics

B. population genetics

C. molecular genetics

D. genomics

E. molecular genetics

Explanation:

Transmission genetics can be defined as the study of the mechanisms involved in the inheritance of genetic material by offspring from parents. This discipline started with the discovery of inherited characteristics in pea plants by Mendel (1865).

Population genetics is a subdiscipline of genetics that studies genetic variation within and between populations. Population genetics is an area that explains how allele and genotypic frequencies change across time, thereby this subdiscipline is closely linked to evolutionary biology.

Genomics is a broad area of genetics that studies the function, evolution, structure, function, mapping and comparison of genomes (i.e., the whole genetic material contained in each cell of a given organism). This discipline aims at understanding entire gene pools. Genomics includes different research areas including structural genomics, functional genomics, epigenomics and metagenomics.

Molecular genetics is a sub-discipline of genetics that studies the mechanisms involved in preserving the genetic material (i.e., DNA and RNA), and to understand how the structure and expression of the genetic material influence the observed variation among organisms.

Can you put leave in conditioner on dry hair
Marysya12 [62]

You can, but I don't recommend it. Conditioner should only be used for damp or wet hair. If used on dry hair, it could ruin.

Hope this helps!
