If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?
Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.
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.

Answer:

Explanation:
In the forest's ecosystem, the trees, shrubs and moss are all producers. They turn water and sunlight into the energy they need to live and grow, through a process called photosynthesis.
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.

Why do the cells of the digestive system secrete proteolytic enzymes, such as pepsin, in their inactive forms
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

An object is subjected to an unbalanced force. What happens to the object
A- The object changes speed or direction.
B- The object continues moving at a constant speed.
C- Nothing changes.
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.
When an object experiences an imbalanced force, the item either alters its speed or its motion's direction.
Option A is the proper response, thus.
What is the second law of Newton?The resultant force exerted on an object is proportional to the rate of change of momentum, according to Newton's Second Law.
Force is equal to the product of an object's mass and acceleration because acceleration is the change in velocity expressed by either a change in speed or a change in direction.
One of two things occurs when an item encounters an imbalanced force: either the object alters its speed or its motion direction.
As a result, choice A is the right response.

why the food pyramid is wider at the base and very narrow at the top
Answer:
The wider base stands for foods with little or no solid fats or added sugars. These should be selected more often. The narrower top area stands for foods containing more added sugars and solid fats. The more active you are, the more of these foods can fit into your diet.
Explanation:
A food pyramid can be defined as a graphical representation of a set of dietary guidelines and optimal number of servings from each of the basic food groups, which are to be eaten daily by an individual.
Basically, a food pyramid illustrate the principles of good nutrition and contribute towards a healthy balanced diet.
Foods and drinks that are highly rich in nutrients such as fruits and vegetables are found at the wider base (bottom) of the food pyramid while foods that are high in sugar, cholesterol, salt and fat are placed at the top.
In conclusion, the food pyramid is wider at the base because that is where all the very good and nutritious foods are illustrated while it is very narrow at the top because those are unhealthy foods and drinks for humans.

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.

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.

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.
