"Large molecules such as hormones" types of materials are expelled from cells during exocytosis.

<u>Answer:</u> Option A

<u>Explanation:</u>

The mechanism whereby a cell transfers secretory products to the plasma membrane via the cytoplasm is termed as "exocytosis" while material passage into the cell is known as "endocytosis". Exocytosis is need for removing waste material from cell.

In exocytosis, mechanism huge quantity of molecules which means bulk transport is performed.Responsible for secretion of digestive enzymes and hormones. In this process, membranes-bound secretory vesicle pass to the cell membranes while their material like water-soluble molecule get secreted in the extracellular atmosphere.

You cross two red griffins with blue eyes and produce offspring that are: red with blue eyes, red with green eyes, white with bl
sergejj [24]

Answer:

The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.

Explanation:

In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.

Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.

African cichlids are a group of closely related fish species. There are at least 500 known species living in three small lakes.
Readme [11.4K]
The correct answer that would best complete the given statement above would be the term ADAPTIVE RADIATION. African cichlids are a group of closely related fish species. There are at least 500 known species living in three small lakes. Over time, specialized teeth and body colorations have evolved for each species in response to mutations and competition for food and mates. This change over time is an example of ADAPTIVE RADIATION. Adaptive radiation by definition, is <span>the diversification of a group of organisms into forms filling different ecological niches.</span>

Lila is a track and field athlete. She must complete four laps around a circular track. The track itself measures 400 meters fro
tekilochka [14]

Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.

Explanation:

Formulae :\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}

\text{Velocity}=\dfrac{\text{Displacement}}{\text{Time}}

Given: Length of track start to finish=  400 meters

After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters

Time taken by Lila =   6 minutes

= 6 × 60 seconds      [There are 60 seconds in 1 minute.]

= 360 seconds  

Then, \text{Speed}=\dfrac{1600}{360}=\dfrac{40}{9}m/s

= 4.44\ m/s

But from start to finish displacement = 0 m   [displacement is the shortest distance between starting point to the finishing point]

So, \text{Velocity}=\dfrac0{360}=0\ m/s

Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.

koban [17]
Tons of rain can cause an ecosystem to flood, killing species that are not meant to withstand lots of water. Ocean temperature can slow down or speed up evaporation, affecting precipitation rates.
