7 0

Answer:

The correct option is : c) Glycerophospholipids

Explanation:

The lipid bilayer of the plasma membrane is composed of glycerophospholipids, sphingolipids and sterols.

The sphingolipids are the derivatives of sphingosine. Whereas, <u>the glycerophospholipids are the derivatives of </u><u>phosphatidic acids</u>.

Phosphatidic acid are the phospholipids that give one glycerol molecule, one  molecule of phosphoric acid and two fatty acids molecules on hydrolysis.

<u>Therefore, Phosphatidic acid is a precursor of glycerophospholipids.</u>

How can two organisms with a dominant trait for a specific feature produce an organism with a recessive trait for the same featu
Liono4ka [1.6K]

Answer:

If the two organisms are heterozygous for the dominant trait.

Explanation:

For every trait, a diploid organism receives two forms of gene called ALLELE, from each parent. Allele is the variant form of a gene.

According to Mendel's law of dominance, for a particular trait, an allele is capable of masking the expression of another allele in a gene. The expressed allele is called the DOMINANT allele while the masked allele is called the RECESSIVE allele. Due to this, an organism can express a dominant trait even in a combined or heterozygous state i.e. different alleles.

When the two heterozygous organisms mate or are crossed, they undergo meiosis and their alleles are separated into GAMETES according to Mendel's law of segregation. For example; an organism with genotype (genetic make-up) Aa will produce gametes with A and a alleles.

Note that, a recessive trait can only be expressed in a homozygous state i.e. same allele. Hence, the two heterozygous organisms will produce gametes containing the recessive allele, which will likely combine to produce a recessive phenotype or trait.

Artyom0805 [142]

Answer:

Connective Tissues

Explanation:

According to my research on studies conducted by various medical professions, I can say that based on the information provided within the question this scientist is most likely looking at Connective Tissues. These are tissues in which material secreted by the cells is fills up the spaces between the cells, thus connecting or binding otherwise separate tissues or organs. Which is what the scientist seems to be describing.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
