does anyone know the answer??! HERE IS THE Q:
In pea plants, green peas are dominant to yellow peas. What would be the phenotypic percentages of the offspring that would result in a cross between a green heterozygous pea plant and a yellow pea plant? *
50% Gg, 50% gg
100% Gg
50% green, 50% yellow
100% green
Answers
Answer and Explanation:
Here is the given information:
Green peas are dominant, so we will put them as capital G.
Yellow peas are recessive (meaning they don't show if there is a dominant allele - trait), so we will pit them as lowercase G.
A Green Heterozygous (different, in this case, has both G and g, or Gg) pea plant.
A Yellow pea plant (will have both lowercase g, or gg).
To find the phenotypic percentages, we make a chart and solve.

Describe how you would use Random Sampling to determine the population of dandelions in your yard.
Answers
Answer:
randomly select different areas to count the dandelions, average the numbers and then multiply by the number of plots your grid contains. 6. In a forest that measures 5 miles by 5 miles, a sample was taken to count the number of silver maple trees in the forest.
Random sampling is used in sampling biological products. It is made up of subsets from the larger population in which the subset of individuals is selected randomly with equal probability.
It is used to collect the data for your research work.For sampling the dandelions randomly we will first choose a distinct random area for computing the dandelion.Estimate the average of the numbers determined before.Now multiply the average with the design your framework contains or with the total number of squares in the yard.Therefore this is how you calculate the random sample size.

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)
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%’.

Is the mass–kinetic energy relationship directly proportional (as one variable increases, the other increases) or inversely proportional (as one variable increases, the other decreases)?
Answers
Answer:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity.
Explanation:
The mass-kinetic energy relationship is ; Directly proportional
The Kinetic energy of an object is directly proportional because an increase in the kinetic energy of a moving object leads to an increase in the mass of the object and also to the increase in the velocity of the object squared.
i.e. K.E ( kinetic energy ) = [tex]\frac{1}{2} mv^2[/tex]
Hence we can conclude that the mass-kinetic energy relationship is directly proportional.

What is gene flow?Gene migration is another name for gene movement. The movement of genetic material from one group to another is referred to as gene flow.
Through migration, gene flow can occur between two populations of the same species and is mediated via vertical gene transmission from parent to offspring and reproduction.
Any movement of people and the genetic material they carry from one community to another is referred to as gene flow, often known as migration.
Therefore the movement of genetic material from one population to another is known as gene flow.

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

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.

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.
