if you cross Bb with bb what's is the genotype ratio?
Answers
Answer:
Genotype ratio 1:1, there are two types of genotype BB and Bb in equal ratio.
Phenotype ratio 1:0, because all offspring have allele B. “B” is dominant and there is no bb genotype, so recessive trait will not be shown.
Explanation:
Answer:
I don't know about the ration but it's going to be 25% chance for them to have an offspring with blue eyes as there is a presence of a dominant allele
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

what is gene flow and how might it impact a wolf population
Answers
Answer:
Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.
Explanation:
Gene flow within the population increases the genetic variability in the wolf population variation can be seen.
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.

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.

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.

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.
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.
