Answers

Answer 1

Answer:

False

Explanation:

Individual organisms don't evolve over time. This is because evolution is passed down to offspring over time.

Answer 2
Individual organisms don't evolve. Populations evolve. ... These individuals generally survive and produce more offspring, thus passing their advantageous traits on to the next generation. Over time, the population changes.

25% red, 50% pink, and 25% white

Explanation:

construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.

RR is red and occurs once so that is a 25% chance (1/4)

RW is pink and it occurs twice so that is 50% (2/4)

WW is white which occurs once and it is another 25% (1/4)

25%
A red flowered Snapdragon(RR) is crossed to white flowered Snapdragon(rr). The F1 individuals are Pink flowered(Rr). When F1 individuals are self crossed, in the F2 generation, 1 plant with red flowers(RR-25%), 2 plants with pink flowers(Rr-50%), 1 plant is with white flowers(rr-25%) are formed. The phenotypic ratio is 1:2:1 and genotypic ration is 1:2:1.
So, the correct option is ‘25%’.

Explain why selective breeding of plants takes a long time (

Answers

Hello! Selective breeding means choosing the plants or animals that have the most pronounced desirable characteristics and breeding them. It takes generations to make the desirable characteristics develop more and more, until finally they are at the desired level. Meaning the reason why it takes so long is because you need to breed multiple generations. Hope this helps!

write two sources of each of Nitrogen Phosphorus and potassium required for the growth of plant​

Answers

Answer:

Do Nitrogen, Phosphorus, and Potassium Fertilizers Do for Plants? Nitrogen in Fertilizer. In simple terms, nitrogen promotes plant growth. It is associated with leafy, vegetative growth. Phosphorus in Fertilizer. Phosphorus is involved in the metabolic processes responsible for transferring Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to in making sure plants are healthy as they develop and nutritious to eat after they’re harvested. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.

Explanation: hope im right

Minerals like feldspar and mica are the main suppliers of potassium in soil. The earth provides phosphorus to plants. Usually in the form of synthetic fertilizer or livestock dung, farmers apply phosphorus to soil. The primary source of nitrogen in atmospheric deposition is the combustion of fossil fuels like coal and oil.

What is fertilizer?

Fertilizer, a natural or synthetic substance with chemical components that enhance plant growth and productivity.

The primary sources of potassium in soil are minerals like feldspar and mica. Plants receive phosphorus from the ground.

Farmers add phosphorus to soil, typically in the form of synthetic fertilizer or livestock manure. The burning of fossil fuels like coal and oil is the main cause of nitrogen in the atmosphere.

Plants can take up nitrogen from the soil as [tex]NH^4^+[/tex] and [tex]NO_3[/tex] ions, but most of it is taken up as nitrate due to how common nitrification is in agricultural soils. As plant roots take up water, nitrate readily travels in their direction.

Thus, these are the sources of each of Nitrogen Phosphorus and potassium required for the growth of plant​.

The effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells is the same. However, due to the cell walls of plants, the visible effects differ. Although some effects can be seen, the rigid cell wall can hide the magnitude of what is going on inside.

Answers

Answer:

Yes.

Explanation:

Yes, there is same effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells because both cells are more similar to each other. If a plant or animal cell is placed in a hypertonic solution, water will go outside the cell, and the cell will shrink, in isotonic environment, there is no water movement inside or outside of the cell, so there is no change in the size of the cell, while on the other hand, if a cell is placed in a hypotonic environment, water will enter the cell, and the cell will turgor.

one of the seed banks has been storing seeds of a rare and endangered plant to keep the seeds fresh.120 of the seeds of this plant were selected to be grown out of this 120 seeds only 90 germinated

what percentage of the seeds was not fertile?show all your working​

Answers

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?

Answers

I believe the answer is the NUCLEUS

The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.

What is nucleus?

The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.

DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.

The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.

The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.

Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.

Thus, nucleus is only present is eukaryotic cells.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS

Answers

Answer:

Genotypic ratio = 16 WwDd: 0

Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit

Explanation:

This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).

According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:

WWDD - WD, WD, WD, WD

wwdd - wd, wd, wd, wd

Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.

The genotypic ratio is 4 WwDd: 0

The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.

Explain why males can be carriers for an autosomal disorders but not for an x-lined disorder.

Answers

Answer:

In order to be a carrier, the male must be a carrier of the allele without expressing it phenotypically. This can only happen when the inheritance is autosomal because he has a pair of autosomic chromosomes meanwhile he only has one X chromosome. So when the inheritance is X-linked, the allele of the X chromosome will always be phenotypically expressed
