What are the macromolecules DNA and RNA referred to as?

True [87]

Answer:

Nucleic Acids

Explanation:

Between carbohydrates, lipids, proteins, and nucleic acids, DNA and RNA molecules most accurately fall under the macromolecular category of nucleic acids.

Explain how you determined wether or not a cell was dividing.

FromTheMoon [43]

The parent cell divides into two "daughter" cells. This will repeat over and over, and this is what we define as the cell cycle!

Fun Fact: Each stage of the cell cycle, such as G1 (Growth/Gap 1), Synthesis/ Stage, then G2/ Gap 2 stage, then following mitosis, has their own checkpoint! These checkpoints review/ revise what the cell has done during the stage.

During dna replication what two processes must occur before the two strands separate

mojhsa [17]

The two processes that occur before the two strands of a DNA molecule can separate during separate during the DNA replication is that their hydrogen bonds should be broken in between of the molecule and bases and that the molecule and the bases of it must be also unwind.

FrozenT [24]

An enzymatic weight-gain supplement claims to help users digest all carbohydrates in fruits and vegetables. Cellulase enzyme is present.

<h3>What is cellulase ?</h3>

Cellulase (systematic name 4—D-glucan 4-glucanohydrolase) is any of a number of enzymes that catalyse cellulolysis, the breakdown of cellulose and some related polysaccharides, and is primarily produced by fungi, bacteria, and protozoans.

Endohydrolysis of (14)-D-glucosidic linkages in lichenin, cereal -D-glucan, and cellulose

The term is also applied to any naturally occurring combination or complex of numerous such enzymes that break down cellulosic material sequentially or cooperatively.

Cellulases convert the cellulose molecule into shorter polysaccharides and oligosaccharides, as well as monosaccharides (or "simple sugars") like -glucose. Because it makes a key plant component usable for food and use in chemical reactions, cellulose breakdown has significant economic significance. The 1,4-D-glycosidic bonds in cellulose, hemicellulose, lichenin, and cereal -D-glucans are hydrolyzed in this particular process. Compared to the breakdown of other polysaccharides like starch, the breakdown of cellulose is particularly challenging because the molecules of cellulose bind tightly to one another.

you are working with a population of snails. during the mating season, you observe that individuals in the population will only

kirza4 [7]

The statement: Allele frequencies will stay the same, but genotype frequencies will change over time is False, option B

<h3>What are dominant and recessive traits?</h3>

Dominant traits are traits which whenever the allele for such traits appear will always be expressed in the offspring.

Recessive traits are traits which are masked by the dominant trait whenever the allele for the dominant traits appear. Recessive traits are only expressed in the absence of the dominant traits.

In the snail population, the M is dominant over m and that selection acts against hom0zygous recessive individuals.

Also individuals in the population will only mate with others of the same genotype.

Overtime, it will be observed that the allele frequencies and the genotype frequencies will change over time.

In conclusion, the allele frequency and genotype frequencies of the snail population will change over time.

Note that the complete question is given below:

You are working with a population of snails. during the mating season, you observe that individuals in the population will only mate with others of the same genotype (for example, mm individuals will only mate with mm individuals). there are only two alleles at this locus (M is dominant; m is recessive); you have determined that the frequency of the M allele = 0.4 and that selection acts against h0m0zygous recessive individuals. Consider whatbwill occur in this population overbthe course of many generations and mark A for True or B for False for each of the following statements:

Allele frequencies will stay the same, but genotype frequencies will change over time.
