Answer:

A. The temperatures are too high.

Explanation:

A desert is a region with extremes of temperatures and little to no rainfall.

Organic matter are the remains of organisms that have died. They are a very important component of soils.

Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.

Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.

Which of the following would differ if you compared the same reaction taking place with and without an enzyme
SIZIF [17.4K]

Answer:

The correct answer is - option C.

Explanation:

Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.

Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.

Thus, the correct answer is - option C.

A friend of yours claims to have identified a gene that causes a human disease! Your friend says that they have sequenced the DN
sattari [20]

Answer: Point mutation is easily reversible, thus non-lethal

Explanation:

Point mutation is caused by exchange of a single nucleotide for another. These change is called

1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)

2) Transversion (when a purine base substitute a pyrimidine base).

However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate

Select the three statements that are true. To review the germ layers and the terminology associated with body cavities, see the
soldier1979 [14.2K]

Answer:

A diploblast has no mesoderm.  

A pseudocoelom has the same functions as a true coelom.  In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.

Explanation:

Diploblast organisms are the ones that have only two primary germ layers. These organisms have outer ectoderm and inner endoderm but no mesoderm. Example: Cnidarians

A true coelom is derived from mesoderm and is completely lined with tissue derived from mesoderm. The outer and inner linings of the coelom are made of muscle layers that are developed from the mesoderm.  

A pseudocoelom is the one that is incompletely lined with mesoderm. Both pseudocoelom and a true coelom serve as shock absorber and provide space wherein the internal organs can be placed. The fluid present in them sere as medium for transport of nutrients, gases, etc.
