white eyes are recessive in flies. can two red eyed flies have white eyed offspring
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies :
Red eye (R) is dominant trait. White eyes (r) is the recessive trait.When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square :
Rr X Rr
Alleles R r
R RR Rr
r Rr rr
In the offspring, the probabilities are:
50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.This is the possibility of two red-eyed flies having white-eyed offspring.

diversity is increased
by process of Spocation?
Answer: In eukaryotic species—that is, those whose cells possess a clearly defined nucleus—two important processes occur during speciation: the splitting up of one gene pool into two or more separated gene pools (genetic separation) and the diversification of an array of observable physical characteristics (phenotypic ...

Give two regions of the body where the bones act as a protection for vital organs. name the bones and the organs they protect.
Answer:
The skull protects the brain, ribs form a cage that shelters the heart and lungs
Explanation:
The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax). The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs. Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.

A ball, starting from rest at Position 1, rolls down and then up a curved track towards Position 5. When it reaches Position 5. it rolls back down the track
5
Which description below is most consistent with what you can expect from the ball's motíon?
O The ball will roll as high as Position 1 since energy cannot be created or destroyed
The ball will roll past Position 1 since energy cannot be created or destroyed.
The ball will roll as high as Position 2 since some of the energy will be transformed to heat.
The ball will roll as high as Position 3 since that position has the least potential energy
Answer: C
Explanation:
Answer:C. When the ball rolls from position 1 to 3, and from Position 5 to 3

How is land subsidence related to a rise in human population?
Land subsidence happens when the increased demand for water is countered with sound agricultural practices.
Land subsidence happens when the increased demand for water causes the levels of the water table to rise.
Land subsidence happens when the increased demand for water causes the levels of the water table to lower.
Land subsidence happens when the increased demand for water results in rapid recharging of aquifers.
Land subsidence is related to human population growth because soil subsidence occurs when increased water demand causes groundwater levels to drop.
What causes subsidence?Subsidence is a phenomenon of lowering of the ground surface due to changes in the underground support. The phenomenon occurs in several places in the world due to the
extraction of wateroil and gas from the subsoil.With this information, we can conclude that Land subsidence is related to human population growth because soil subsidence occurs when increased water demand causes groundwater levels to drop.

Which of the following explains how photosynthesis takes place in a plant?
Answer:
D
Explanation:
Carbon dioxide enters through the stomata on the underside of the leaf.
Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).
Oxygen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.

A student conducted a comparative investigation to test the hypothesis that different areas of New York City have different levels of air pollution.
Which is a likely benefit of this comparative investigation?
It provides her with a large amount of information about air pollution in New York City.
It provides her with results that are valid for a long time.
It requires that she observe a limited number of variables.
It allows her to learn about the causes and effects of air pollution in major cities.
Particles that are both solid and liquid, as well as some gases that are suspended in the air, are what produce air pollution. These gases and particles can be produced by factories, volcanoes, wildfires, dust, pollen, and vehicle and truck emissions.
The largest causes of air pollution come from industrial sources, power plants that provide electricity, and fossil fuel powered cars. The constant combustion of fossil fuels emits chemicals, emissions, and air pollutants into the atmosphere.

Represents exponential growth
Answer:
The variable b represents the growth or decay factor. If b > 1 the function represents exponential growth. If 0 < b < 1 the function represents exponential decay.

in an experiment what should be the relationship between the control group and experimental group?
Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.

2. In some dogs the allele for barking is dominant to the allele for non barking. How would a breeder get a strain of pure breeding barkers? Assume he has males and females of both types.
Answer:
Explanation:
Dominant traits are traits that are visible in the phenotype of an organism.
If barking is dominant in some allele of the dog and it has both male and female then a cross between the male and female with the dominant allele for barking will give a strain of pure breeder barkers.
A recessive allele cannot breed a pure barker because it does not have the allele for barking.
Hence a cross between two individual that dominos of the allele will breed true type.

A corn field is divided into four parts each part is ‘treated’ with a different fertilizer to see which produces the most corn. What is the dependent variable?
1. Different Fertilizers
2. Corn Production
Answer:
The correct answer is - 2. corn production.
Explanation:
The dependent variable of a scientific investigation is a variable that depends on the independent variable. It is a variable that is required to check or find the effect of the independent variable and also known as output value that helps to know the effect of input values or independent variable.
In this case, the input value or the independent variable is different fertilizer as it is the only variable that is manipulated by the researcher, and due to this manipulation, the production of the corn affected which is the dependent variable as it depends on the independent variable.
