Answer:
One benefit is the adaptability and survivability of the corn in a condition that favors this genetic strain.
They are all susceptible to almost the same unfavorable condition and lack adaptability.
Explanation:
Since all the corns have the same genetic strain, this means that they all are closely related and are probably progeny of the same long line of corn. Having the same genetic strain can be favorable if this strain has been selected to suit the conditions of their cultivation area and also to bolster resistance to some dangerous diseases.
In the case where a new condition or disease outbreak is the case, then this is a set back since the genetic strain has not been used to this new conditions. This can lead to extensive damage that may even be close to, if not lead to a complete extinction of this particular corn strain.
Answer:
The benefit is that corn plants will always yield a consistent product because farmers selected against negative genetic characteristics. However, if there’s an environmental change or the threat of a disease, there would be little genetic variation in the crop to improve its chances of survival.

In wild populations, evolution is often causedby natural selection. Based on what you have observed, how does natural selection occur?
Answer:
In natural selection, genetic mutations that are beneficial to an individual's survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce. ... Those differences are at least in part determined by their genes.

1. **How does the amount of carbon the US emits compare to other countries?
Answer:
5.1 billion metric tons of carbon is emitted by U.S as compared to other countries which emits about 32.5 billion metric tons of carbon.
Explanation:
U.S emits about 5.1 billion metric tons of carbon in the atmosphere which contribute in air pollution also helps in rising the temperature of the earth atmosphere because carbondioxide is a green house gas which increases the earth temperature. The main reason of high amount of carbon emission is the high number of industries and more fossil fuels is burnt in the engines of vehicles.

a cell with a diploid number of 24 undergoes meiosis, how many chromosomes are in each daughter cell?
Answer:
it will have 12
you are welcome :)
When a cell with a diploid number of 24 undergoes meiosis, each daughter cell will have 12 chromosomes.
What is meiosis?Meiosis is a process of cell division that generates haploid cells having half the number of chromosomes as the cell. It plays a role in reproduction by enabling the merging of two haploid cells to form a diploid cell with the complete set of chromosomes.
In this scenario the parent cell contains 24 chromosomes resulting in each daughter cell possessing 12 chromosomes.

Kerry was investigating how the angle of incidence of radiant energy on a surface affects the rate of temperature rise of the surface. A paper pocket holding a thermometer was placed near a lamp. The paper pocket was then placed at various angles so that the angle of incidence of the radiant energy varied. Kerry made sure the distance to the lamp was the same for each of his trials.
The following table shows the data recorded by Kerry.
a. What is the manipulated variable?
b. What is the responding variable?
c. Identify one controlled variable.
Answer:
a. What is the manipulated variable? the angle of incidence of the radiant energy
b. What is the responding variable? the rate of temperature rise on the paper surface
c. Identify one controlled variable? the distance of the paper to the lamp
Explanation:
Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the angle of incidence of the radiant energy to evaluate how it affects the rate of temperature rise of the surface.Responding variable: Refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the rate of temperature rise on the paper surface, and its value depends on the angle of the paper.Controlled variable: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example the distance to the lamp is the controlled variable, as it was the same for each of his trials.someone plsss. Using the data, describe the relation between the angle of incidence and the rate of temperature change

Answer:
Autoimmune Hemolytic Anemia (AIHA)
AIDS & chromosomal breakage syndromes
Athlete's foot. Chickenpox or shingles
Explanation:
Autoimmune Hemolytic Anemia (AIHA) disease affects the blood. It leads to production of substances that destroy the red blood cells (RBCs) and hence leads to anemia (low hemoglobin).
Some of the diseases that affects the T cells are acquired such as immune deficiency (AIDs) and chromosomal breakage syndromes (CBSs) while some are inherited from parents such as DiGeorge syndrome, chromosomal breakage syndromes etc.
Athlete's foot. Chickenpox or shingles produces rashes on feets
PLEASE HEP ME WITH THESE QUESTIONS. 1.(Solar system, Galaxy): the Sun, the planets, and other celestial bodies that are held by the
Sun’s gravitational attraction.
2. (Black hole, Eclipse): a partial blocking of light from the passage of an object between the
celestial body and the observer or between the celestial body and its source of illumination.
3. (Equator, Axis): an imaginary line through Earth that extends from the North Pole to the South
Pole.
4. (Cyclic pattern, Sporadic pattern): an event or process that contains multiple steps that repeat.
5. (Climate, Seasons): the four divisions of the year based on changes in temperature caused by
varied amounts of sunlight and the tilt of Earth.
Answer:
1. solar system
The galaxy is much larger than the solar system, and since the question only includes the sun and the other planets, and what's close to that like debris, we should limit this to the solar system.2. eclipse
A black hole is a discontinuity from which light cannot escape. It's by no means partial or temporary, unlike an eclipse, which is when a celestial body covers another (like when the moon temporarily covers the sun).3. axis
The equator is like the circumference of the sphere, and the axis is like a diameter that goes straight through the earth. The axis goes from pole to pole, which is through the earth, so you know it's the correct answer.4. cyclic pattern
"Cyclic" comes from "cycle" which means a consistent pattern. "Sporadic" means with no pattern, capricious.5. seasons
There are four seasons and there aren't four climates, so this should be fairly simple!One global warming prediction might be
A) fewer climatic weather change events
B) increased cases of malaria
C) increased resources and plant growth periods
D) lower overall coastal flooding events

Hich cell types are low in aplastic anemia? select all that apply. leukocytes hepatocytes erythrocytes thrombocytes osteocyte
Answer:
Erythrocytes, leukocytes and thrombocytes
Explanation:
Aplastic anemia is a type of rare condition in which the body stops producing enough new blood cells. This might occur as a result of damage to the stem cells in the bone marrow that produces these blood cells which includes the rest blood cell, the white blood cells and the platelets. The most common cause of this condition is the immune system attacking and damaging the stem cells in the bone marrow.
Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answer.
Answer:
The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.
Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.
BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.
The activity factors in Harris Benedict Equation are:
for no exercise = 1.2
exercise for 1 to 3 days/week or light exercise = 1.375
exercise for 3-5 days/week or moderate exercise = 1.55
exercise for 6-7 days a week or hard exercise = 1.725
exercise for 2 times training = 1.9
So, calculation for my calorie needs is as following:
BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945
Calorie needs = BMR x 1.55
= 974.945 x 1.55
= 1511.16 calories

Logging involves people cutting down trees to acquire timber for uses such as building homes and making paper. How would logging affect a pine forest ecosystem? Choose the two that apply.
A. It would remove all the soil from the area.
B. It would change the plant populations in the area.
C. It would remove all the populations from the area.
D. It would change the animal populations in the area.
Answer:
Explanation:
Pues cambiaría la población de animales y en el área espero que esté bien la pregunta
B. It would change the plant populations in the area.
D. It would change the animal populations in the area.
Logging can have significant impacts on a pine forest ecosystem.
What is the effect of removing sunlight ?Removing trees can change the amount of sunlight reaching the forest floor, altering the growth patterns and composition of the plant populations.
Clear-cutting can also remove critical habitats for animals, leading to changes in the animal populations in the area. However, logging typically does not remove all the soil from the area, and it does not necessarily remove all the populations from the area, as some plants and animals may still be able to survive in the disturbed ecosystem.
Logging is the practice of cutting down trees to obtain timber for commercial purposes, such as building materials, paper products, and furniture. It is a widespread industry that can have significant environmental and economic impacts.
