The cells activities are controlled by the DNA. The DNA is contained in a nucleus in some cells, and in others it is in the Cytoplasm.

A lack of some basic biological requirement such as water, which produces a drive to obtain that requirement, is known as the?

Sliva [168]

Drive reduction approach to motivation, this theory states that when an individual has been deprived of biological resources such as energy, water or sleep, others. They tend to result to impulse or drive. These basic needs arise an action to obtain this need is required.

In their first attempts to genetically engineer a cow that will make and secrete human growth hormones in milk, scientists found

Arte-miy333 [17]

Answer:

C. The cows will reproduce, but neither males nor females will reproduce the altered gene.

Explanation:

I just had this question lol but because it said in the question “However, they discovered that the altered gene gets lost from the genome during meiosis.” Shows that the cows aren’t able to reproduce the altered gene. It never stated they can’t reproduce.

Interpret the Punnett square. A Punnett square with four rows and four columns. The first row is labeled big-A, big-B. The secon

Naddika [18.5K]

Answer:

The genotypes shown represent gametes. False

One of the possible offspring genotypes is AABB. True

The parent genotypes are ABAbaBab×ABAbaBab. True

This cross shows two alleles for two traits. True

The gametes are diploid and the offspring are diploid. False

The genotypes shown are correct for a dihybrid cross. True

Explanation:

║ AB ║ Ab ║ aB ║ ab

AB║ABAB ║ ABAb║ABaB║ABab

Ab║ AbAB║ AbAb ║AbaB║Abab

aB║aBAB ║ aBAb ║aBaB║aBab

ab║abAB ║ abAb ║abaB ║abab

Drawing the Punnett square we can deduce that the genotypes shown do not represent gametes because there are more than 2 pairs of chromosomes.

As shown in the second column second row of the Punnett square one of the possible genotypes is AABB, it is distributed different (ABAB) but it is the same possible genotype.

The parents' genotypes are the ones that are written in the first columns and first row, they coincide with the ones in the statement.

A dihybrid cross shows the cross between two genes that have different traits.

The gametes are always haploid and the offspring are diploid because the two gametes come together.

A young man wants to determine if he is a descendant of Henry of Navarre and Eleanor of Aquitaine—two of his favorite historical

mars1129 [50]

Answer:

He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.

Explanation:

Mitochondrial DNA haplotypes are specific regions of mitochondrial DNA that cluster with other mitochondrial sequences to show the phylogenetic origins of maternal lineages.
Mitochondrial DNA haplotypes are associated with a range of phenotypes and disease.
Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.

Sublimation is the opposite of deposition just as evaporation is the opposite of fusion transpiration freezing condensation

Lena [83]

<span>A condensation is a process where liquid changes into a gaseous form also known as water vapour. It occurs in the atmosphere when the temperature rises.
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.</span><span>
