C) transform

Explanation:

The San Andreas fault is a transform fault margin as a result of the Pacific plate moving horizontally with the North American plate.

There  are different types of plate interactions.

  • At a convergent margin, plates comes together.
  • At a divergent margin, plates moves away from one another.
  • At a transform margin, plates moves past one another horizontally.

The San Andreas is one of those margins in which plates moves past one another horizontally. This is a typical transform margin resulting in series of earthquake activities on the surface.

Why does dna contain thymine but rna contains uracil?
uysha [10]
<span>Thymine is harder to make, but more stable. DNA needs to keep information safe for a long time, so it makes sense to use thymine. But RNA is made and used quickly, and small mistakes don’t matter as much, so the easier to make uracil does the job.</span>

prisoha [69]

Answer:

B. Oncogene

Explanation:

A gene that makes the body cells to divide in an uncontrolled manner is called an oncogene. An oncogene is responsible for the development of tumors due to disturbed regulation of cell division. The gene src makes the cells to enter the process of cell division in response to the growth factors.

However, the mutant src gene does not require the presence of growth factors and signals the cells to enter the process of cell division even in the absence of the growth factors. Since the mutant src gene causes uncontrolled cell division, it represents an oncogene.

Define the following terms with examples:
Mashcka [7]

1) Chordata=A chordate is an animal of the phylum Chordata. All chordates possess 5 synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa

2) Vertebrates=vertebrate, also called Craniata, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone.

3)Invertebrates=Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.

4) Poikilothermic animals=A poikilotherm is an animal whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress.

5) Homeothermic animals=The term homeothermic refers to the warm-blooded animals which have constant and relatively higher temperature. They are animals which can maintain their internal body temperature. Complete answer: Homeothermic animals are warm-blooded and maintain a constant body temperature, for example birds and mammals.

6) Oviparous= producing young by means of eggs which are hatched after they have been laid by the parent, as in birds.

7)Vivaparous=bringing forth live young which have developed inside the body of the parent

Sorry if it's incorrect

Have a nice day
