Years ago, farmers determined that suppressing flower development in the wild mustard plant gave rise to the plant we know as broccoli. This is an example of ________.
To get the best from their produce, farmers tend to alter the features of the crops they have presently. The phenomenon that explains the action taken by the farmers above is;
Artificial SelectionArtificial Selection is the process of choosing desirable traits from plants and animals with the view of getting a new generation that is healthier and that possesses much better features.
In the case of the farmers above, they effected artificial selection by suppressing flower development in the wild mustard plant thus giving rise to broccoli which had more desirable features.
Therefore, the answer, artificial selection is correct.

By 12 weeks, the uterus is just ____________ to the level of the ____________ and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the ____________ .
Answer: 1. superior 2. pubic symphysis 3. urinary bladder
Explanation:
Given our understanding of the human anatomy, we can confirm that by 12 weeks, the uterus is just superior to the level of the pubic symphysis and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the bladder.
As the question tells us once the spaces are filled in, the uterus, which holds the fetus during development, expands as the fetus grows in size. This expansion causes it to extend to the spaces superior to the pubic symphysis and the space occupied by the bladder.
The expansion of the uterus into the space occupied by the bladder causes this organ to have very limited space to expand, thus greatly limiting the amount of urine it can hold which causes more frequent trips to the bathroom.

how to count replicated chromosomes in mitosis
PLEASE HELP
Answer:
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

What is both the thickest and longest nerve in the body?
Answer:
The sciatic nerve
Explanation:
A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.
Are the forces balanced or unbalanced?
Net force = ?
Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.
In physics, we can say that the net forces being applied to an object are balanced when the forces are
Equal in sizeApplied in opposite directionsApplied at the same time.The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.
Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

Where does respiration take place?
Answer: respiratory system
Explanation:
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell's cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

Which two structures engage to create a muscle contraction?.
Muscle contraction occurs when actin connects with myosin.
Muscle contraction occurs thanks to an action potential, which transmits a stimulus to the interior of the muscles.
For fiber tension to occur, the myosin head must bind with actin, slip, release, and then connect with another actin.This electrical signal allows the actin and myosin proteins to move, thereby generating contraction of the muscles.Therefore, we can conclude that myosin is a protein found in muscle fibers in order to bind to actin protein and cause muscle contraction.

how does deforestation affect the rainfall pattern of an area?
Answer:
deforestation can significantly reduce tropical rainfall far from the area where trees have been cut down.
Explanation:
That's the conclusion of new research that shows deforestation can significantly reduce tropical rainfall far from the area where trees have been cut down.That's because air passing over forests picks up moisture given off by trees and plants, fueling rains. When those trees disappear, so does some of that rain.
what factors determine if a species is fit to survive?
Answer: variation, reproduction, and heritability.
Explanation: Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.
Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.
