_____ algae are important in the formation of coral reefs. Brown Red Fire Golden-brown

Answers

Ans.

Coral reefs are underwater ecosystems, made from growth and deposition of living or dead corals. Red algae play an important role in formation of coral reefs. The thread-like structures of red algae trap the sand sediments and particles of sands and cements, which provide mechanical support to the colony of corals and help them to grow.

Thus, the correct answer is option). 'red.'
Hello, NicopiahzDani.

Changes in the DNA sequence, or mutations, help drive

Answers

The answer is evolutionary change.

A mutation is the alteration of a nucleotide sequence in DNA. If a mutation occurs in the genes that control development it will cause great effects on the adult organism. Since these effects are so significant, they will make some evolutionary changes.For example, a mutation could cause parents with genes for bright coloration to get offspring with genes for darker coloration. After a period of time, that darker coloration will be more frequent in the population than before, so it will cause large-scale evolutionary change.

Hi, love!!

The correct answer is Evolutionary change. :)

Explain why tongue rolling ability is a discontinuous variation

Answers

Since tongue rolling ability is determined by a single gene with two separate alleles—the dominant allele, which codes for tongue rolling ability, and the recessive allele, which codes for tongue rolling incapacity—tongue rolling ability is a discontinuous variation.

What is Tongue rolling ability?

The hereditary characteristic known as tongue rolling ability controls whether or not a person can roll their tongue into a tube shape. This characteristic is frequently used as an illustration of a straightforward hereditary trait with discontinuous variation since there are only two possible outcomes: either a person rolls their tongue or they do not.

Either a person has the recessive allele, which prevents them from rolling their tongue, or they have the dominant allele, which allows them to roll their tongue. There is no intermediate or in-between trait, and the presence or absence of the dominant allele is a distinct, plainly observable phenotype.

Therefore, the capacity for tongue rolling is an illustration of a discontinuous variation.

He will be able to roll his tongue, because the 'A' allele is dominant over the 'a' allele. The 'a' allele is recessive. ... Tongue rolling is an example of discontinuous variation: you either can roll your tongue or you can't. Other characteristics, for example height and weight, show continuous variation.
