Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant

Answers

Answer 1

Answer:

C. The green allele is recessive to the yellow allele

Explanation:

Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.

Imagine carefully weighing a metal can, leaving it out in the rain for weeks and weeks until it was very rusted, and then carefully weighing it again. Would the can be heavier or lighter after it was rusted?

Answers

Answer:

The answer would be heavier, though it depends upon the type of metal. Rusting is essentially corrosion. Rust is often caused by a piece of metal getting soaked in water and then being exposed to oxygen. The rust will add more weight to the can so it becomes heavier.

Leaving out metal can in the rain for weeks and weeks until it was very rusted, and then if we carefully weighing it again it can be found that the can weighs more because the rust deposited on the metal can adds more weight.

What is rust?

Rust is referred to as an iron oxide, and a form of corrosion which is caused by a chemical reaction which affects masses of iron and steel.

Once formed, rust starts to eat away at the metal, forming a flaky, orange red coating which weakens the iron. It occurs when the metal reacts with oxygen and water.

A) fruits with seeds
B) fruits without seeds
C) pollen
D) ovules

Answers

Answer:

Pollen reproductive structures consist only

of stamens would be able to produce

Explanation:

No C is the answer

Reproductive structures are structures that make up the reproductive organs of a particular organism. These structures could include either female or the male reproductive organs.

Flowers with reproductive structures that comprise of only stamen would produce only pollen (option c).

Stamens are reproductive organs found in plants and they are male reproductive organs. For fruits with seeds to be formed the male and female reproductive organs must come together to produce a fruit.

Flowers with only the stamen will produce only pollen which is a male gamete that needs to be joined to the female gamete, ovary produced from the female reproductive structure (pistil) in a plant to produce a fruit.

Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.

It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.

The capacity of each generator determines the amount of energy it can supply to a given place.
