Chameleons are generally known as insectivores – carnivorous by nature. Depending upon the size and type of the chameleon the type of insects can be different. But, most of the chameleons eat grasshoppers, crickets, silkworms, flies, and cicadas.

Answer:

you inherit 2 alleles for each genes. one comes from your biological mom and the other comes from you biological father. if the alleles are identical like when both your parents have brown eyes and that it will cause you to have brown eye color. some alleles are dominant while the rest are recessive. the dominant trait is more stronger than recessive trait. It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth. Additionally, one allele may be dominant for one trait but not others.

D

Explanation:

In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food.

Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.

Eukaryotes are distinguished from prokaryotes in that they organelles enclosed within a nuclear membrane. The organisms of spinoloricus are radically different from other known eukaryones in that they lack mitochondria and are able to exist in the absence of oxygen. However, their genetic material is contained within a nuclear membrane and they are therefore eukaryotes rather than prokaryotes.

Taking into consideration the main characteristic of each group, prokaryote, and eukaryote. In the first case, we have that it laks nucleus and has no sexual reproduction, meanwhile, the eukaryote has organelles and has sexual reproduction. Taking this into account we can proceed to answer each part.

Therefore, Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.

Explanation:

Answer:

Yes. Monocots have leaves with parallel venation, and dicots have leaves with reticulate, net-like venation. Describe an example of a plant with leaves that are adapted to cold temperatures. Conifers such as spruce, fir, and pine have needle-shaped leaves with sunken stomata, helping to reduce water loss.

Answer:

goblet cells

Explanation:

Goblet cells are the mucin-secreting glands found within epithelia. Their shape and size look like a goblet, hence named goblet cells, and contain narrow bases and wide apex.

The structure highlighted in goblet cells scattered within epithelia. Goblet cells function for producing mucin, create a protective mucus layer and immunoregulation.

Hence, the correct answer is "goblet cells".

Answer:

it gives water and hold the plant

and contrubite food for the whole part

Explanation:

Answer:

Because water exhibits cohesive behavior.

Explanation:

Cohesive behavior can be explained as a behavior where molecules are attracted to each other.

And this means that,  water molecules are attracted to each  other because of their cohesive behavior. This makes them to be  attracted to other substances, such as the walls of the xylem of plants.

In this case, it is believed that the water molecules behave this  way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.

endoplasmic reticulum

Explanation:

The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins.

Answer:

The correct answer is - option D. produces RNA

Explanation:

SER or smooth endoplasmic reticulum is a membranous, tubular organelle present in most of the eukaryotic cells. These ER lacks the ribosome on their surface as rough ER.

The major functions of this organelles are to produce lipid, hormones, protein, steroids for the complete cell. SER also carries detoxification of the metabolic byproducts of the cell. It acts as a bridge or connector between RER to Golgi apparatus.

Answer:

Synthesis is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.

Explanation:

If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

Each step in the cell division is controlled and regulated by proteins like Cyclins. If a cell does not go through the S phase, it can not go to the G2 phase until the replication process is completed, or until it's programmed cell death.  

-----------------------------------------------

As the cell passes through different steps of cell division, there are auto control mechanisms to ensure that the step was correctly performed and the cell is ready to go to the next step.  

Many regulator molecules act during the different stages of the mitosis process to make it possible.

There are too many factors interacting, activating, and deactivating to pass from one stage to another.

Cyclins are proteins that regulate the whole cell cycle. There are different types of cycling, each of them acting on a different stage.

When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that cycle.

Once that stage is over, that cyclin concentration decreases, and the following one increases.

But if any step was not correctly performed, the cell can not pass to the following one.

During the S stage of the interphase occurs the DNI replication process.

At this point, also occurs the synthesis of histones and other associated proteins.

This is the only stage where the DNI molecule is replicated.

S phase cyclins are in charge of regulating the stage of DNA replication.

If the cell does not go through the S phase, the cyclins of this stage are not activated. And if S phase cyclins are not active, the cell can not go to the G2 phase.  

The cell remains in the S phase until the DNA replication process is correctly done. And if it does not occur, the cell suffer programmed cell death.
