Answer:

Stamen/Pistil

Explanation:

Flowering plants also called Angiosperms are a group of plants characterized by the possession of flowers used for sexual reproduction. The flowers contains the male part and female part. The male part of a flower is collectively called STAMEN while the female part is collectively called PISTIL or STYLE.

The STAMEN is responsible for the production of the male reproductive structure called POLLEN while the PISTIL is responsible for the production of female reproductive structure called OVARY. During reproduction, pollen (containing male gametes, sperm) from the STAMEN are transferred to the stigma (receptive part) of the STYLE in a process called POLLINATION.

6. species Closely related of orchids never mate in the wild because they bloom at different times. This is an example of ______

Dimas [21]

Answer:

temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

Reproductive isolation generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

A good example of the pre-zygotic reproductive isolation process is when closely related by different species bloom at different times. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.

How the does the shape of an enzyme affect the reaction?

kobusy [5.1K]

Answer:

The shape of an enzyme determines which reaction it can catalyze.

Explanation:

Each enzyme is specific to one type of reaction. According to the structure of each enzyme, it has an active site capable of binding to a specific substrate, so the shape of the enzyme determines the type of reaction to be catalyzed.

Once the reaction occurs, the enzyme releases the product of the reaction and the enzyme is available for another reaction.

Regarding the other options:

The shape of an enzyme no depends on the reaction that it needs to catalyze.
Due to their specificity, enzymes can only catalyze one reaction at a time
The shape of the enzyme is not altered after the reaction.

Which process will create new sand in a desert

Nadya [2.5K]

Answer: Wind-blown sand grains striking any solid object in their path can abrade the surface. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
