Answer:

It dont go anywhere because it never existed

Explanation:

Answer: it would be b!

Answer:

25%

Explanation:

ww gives white-eye female

WY gives red-eye male

       ww    x    WY

 F1: Ww   wY   Ww   wY

Ww - red-eye female

wY - white-eye male

Crossing the two F1

           Ww    x    wY

F2: Ww   WY   ww   wY

Remember that white-eye male = wY

Percentage of wY = 1/4 or 25%

Hence, the percentage of progeny in the F2 generation that would be white-eye males = 1/4 or 25%

C

Explanation:

Answer:

Mass of LiCi = 17.9352 gm

Explanation:

Given:

Volume of LiCi = 235 ml

Molarity = 1.80 M

Find:

Mass of LiCi

Computation:

Atomic mass of LiCi = 6.9 + 365.5 = 42.4 gm

Mole(n) = Weight / Atomic mass

1.80 = [W / (42.4 x 235)]1000

Mass of LiCi = 17.9352 gm

Answer:

I think prophase. Correct me please.

Answer:

the correct answer be "Metaphase"

Answer:

The double recombinant individuals are less frequent ---> Abc and aBC

Explanation:

We can know if genes are linked, by looking at the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, meaning that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.

We can recognize the parental gametes because their phenotypes are the most frequent in the descendants, while the double recombinants are the less frequent. Finally, the simple recombinant gametes are the ones with intermediate phenotypes frequencies.  

In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,

while the double recombinants are less frequent.

And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

a. Which phenotype represents the double crossovers

The double recombinants are less frequent ---> Abc and aBC

Answer: it’s c mister

Explanation:

Answer:

The correct answer is - prophase I

Explanation:

Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.

Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.

Answer:

D. potassium

Explanation:

Potassium is not found in an organic compound. Therefore, option D is correct.

Any of a vast group of chemical compounds known as organic compounds contain one or more carbon atoms that are covalently connected to atoms of other elements, most frequently hydrogen, oxygen, or nitrogen.

The building blocks of life's components, such as carbohydrates, fats (lipids), proteins, and nucleic acids, are examples of organic substances. Petroleum and natural gas, which make up the majority of fossil fuels, are also organic molecules.

High molecular weights and complicated structures are features of organic molecules. These are usually insoluble in water but soluble in organic solvents. Potassium is not found in an organic compound. Therefore, option D is correct.

Answer:

aa

Explanation:

A widow's peak is the dominant genotype so one must not have that trait. If it was presented then the woman would have the genotype.

A widow's peak is dominant so the man would be either AA or Aa. Since it stated that his is heterozygous (Hetero meaning two different), his genotype would be Aa (again since a widow's peak is the dominant, it only needs one dominant genotype)

Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

Answer:

More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.
