Answer:

The best answer from the list of options is option D (They are colorless and feed on other, smaller cells)

Explanation:

Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.

Is selection more effective against recessive alleles in haploid or diploid organisms?
svet-max [94.6K]
The selection of more effective which is against recessive alleles in haploid organisms than diploid organisms. This is because haploid organisms contain a single set of alleles if a deleterious allele is present in haploid organisms which will produce its effect immediately as there will be no dominant allele which can prevent the expression of the recessive allele as it happens in diploids. Recessive allele will not produce its effect in presence of the dominant allele in the case of heterozygote which is Aa.
Where there is haploid the selection will be more effective when removing recessive alleles in the population. It is the homozygous recessive condition which as aa then the selection will act against recessive alleles.

Write down 2 things that you remember about density
stellarik [79]

Answer:

Explanation:

Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object's density depends on what it's made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.

Biomolecules are made from simple monomers, yet you find a very high level of diversity. What chemical features make diversity i
Luden [163]

Chemical features like 3 dimensional structure and chemical bonding are responsible for diversity in biomolecules although they are made from simple monomers.

In the case of carbohydrates, both starch and glycogen are made up of glucose monomers yet they differ in the functions which they perform in our body. This difference is because of the chemical bonding and the 3 dimensional structure.

Similarly in protein biomolecules, amino acids act as the monomers but they differ in function due to their 3 dimensional structure. Nucleotides are the building blocks of both RNA and DNA. RNA and DNA perform different functions in the body. DNA stores ad transfers genetic information while RNA is responsible for directly coding for amino acids.
