Answer:
Humans: 46 chromosomes (23 pairs)
Pumpkins: 40 chromosomes (20 pairs)
The number of chromosomes in pumpkins to the number of chromosomes in humans is Humans: 46 chromosomes (23 pairs) and Pumpkins: 40 chromosomes (20 pairs)
What is the number of chromosomes in different animals?If a dog has 78 chromosomes in each of his cells, each set of DNA has two sets of chromosomes because dogs are a diploid species so it would be 78/2 and in each cell a dog with 78 chromosomes would have 39 molecules of DNA in each of his cells.
The final products of meiosis in males is four sperm cells and in females it is one ovum and three polar bodies. Thus, the final product of meiosis is four sperm cell in male and one ovum in female with three polar bodies. The main objective of meiosis is to produce gametes, the sperm and eggs, with half of the genetic character of the parent cell.
Meiosis has been defined as the process in which a single cell divides into two identical daughter cells and the process is known as cell division. Meiosis has a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes.
Therefore, The number of chromosomes in pumpkins to the number of chromosomes in humans is Humans: 46 chromosomes (23 pairs) and Pumpkins: 40 chromosomes (20 pairs)

What is meningitis? (ANATOMY)
Answer:
Inflammation of brain and spinal cord membranes, typically caused by an infection.
Meningitis is usually caused by a viral infection but can also be bacterial or fungal. Vaccines can prevent some forms of meningitis.
Symptoms include headache, fever, and stiff neck.
Depending on the cause, meningitis may get better on its own, or it can be life-threatening, requiring urgent antibiotic treatment.

Answer:If you were a single-celled organism and you lived in a nutrient-rich place, staying alive would be pretty straightforward. For instance, if you were an amoeba living in a pond, you could absorb nutrients straight from your environment. The oxygen you would need for metabolism could diffuse in across your cell membrane, and carbon dioxide and other wastes could diffuse out. When the time came to reproduce, you could just divide yourself in two!
However, odds are you are not an amoeba—given that you're using Khan Academy right now—and things aren’t quite so simple for big, many-celled organisms like human beings. Your complex body has over 30 trillion cells, and most of those cells aren’t in direct contact with the external environment.^1

The following four ears of corn were taken from separate plants. Each kernel represents an offspring. The kernels on the four ears were counted for the color trait (purple or white) and/or sweetness trait (starchy or sweet). The data gave these phenotypic ratios for the four ears:
Ear #1 – 3 purple : 1 white
Ear #2 – 3 starchy : 1 sweet
Ear #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Ear #4 – 1 purple : 1 white
Which traits are recessive?
Answer:
the answer is white and sweet, i just took the quiz
Explanation:
The phenotypic ratio provides information about how many genes are involved in the cross, which is the dominant trait and which is the recessive trait. In the exposed example, white and sweet are the recessive traits.
-------------------------------
By looking at the phenotypic ratio of the progeny, you can tell which trait is the dominant one and which is recessive.
Let us assume two diallelic genes, each coding for one trait.
Let us also say that these genes assort independently -they are not linked-, and they do not interact with each other.
When we are only considering one single gene,
the phenotypic ratio after crossing two heter0zyg0us individuals is 3:1. In these situations, we expect to see 3/4 of individuals expressing the dominant trait, and 1/4 expressing the recessive trait.the phenotypic ratio after crossing a heter0zyg0us individual with an h0m0zyg0us recessive one is 1:1. We expect to see 2/4 of the progeny expressing the dominant trait and 2/4 the recessive trait.When we are only considering two genes simultaneously, we expect to find the following phenotypic ratio 9:3:3:1
9/16 individuals expressing both dominant traits3/16 individuals expressing one dominant trait and one recessive trait1/16 individuals expressing both recessive traits.
Now let us analyze each Ear,
Ear #1 – 3 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are purple and 1/4 is whiteDominant trait: purpleRecessive trait: white
Ear #2 – 3 starchy : 1 sweet
Only the sweetness trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are starchy and 1/4 is sweetDominant trait: starchyRecessive trait: sweetEar #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Both traits are considered. The phenotypic ratio is 9:3:3:1Two dihybrid individuals must be involved in the cross9/16 are purple and starchy, 3/16 are purple and sweet, 3/16 are white and starchy, and 1/16 is white and sweetDominant trait: purple and starchyRecessive trait: white and sweetEar #4 – 1 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 1:1One heter0zyg0us individual and one h0m0zygous recessive individual must be involved in the cross2/4 are purple and 2/4 are whiteDominant trait: PurpleRecessive trait: WhiteThe recessive traits are white color and sweet taste.

What best explains how they should complete the table?
with “Inside the nucleus,” because the particle is a proton
with “Inside the nucleus,” because the particle is a neutron
with “Outside the nucleus,” because the particle is a proton
with “Outside the nucleus,” because the particle is an electron
Explanation:
Protons and neutrons are subatomic particles found in the atom of any substance.
These particles collectively determines the mass number of the atom.
Protons are positively charged particles found in the nucleus of an atom. Neutrons do not carry any charges and are also found in the nucleus. Electrons are negatively charged particles.Electrons occupy the extranuclear space of an atom.
Answer:
Depends, you have to give us a table, let me explain how to answer this.
Explanation:
“Inside the nucleus,” because the particle is a proton
For this to be true, it has to have a mass (amu) of 1 and it has to have a positive charge
“Inside the nucleus,” because the particle is a neutron
For this to be true, it has to have a mass (amu) of 1 and it has to have a neutral charge
“Outside the nucleus,” because the particle is a proton
This is instantly wrong because protons are located in the nucleus
“Outside the nucleus,” because the particle is an electron
For this to be true, it has to have a mass (amu) of 1/2000 and it has to have a negative charge

If a cell with little hydrogen peroxide begins producing a large amount, what will happen to the rate at which the hydrogen peroxide is broken down
Answer:
Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product. The result is an increasing amount of foam produced in your cup as you increase the amount of H2O2 in your reaction.

If
there were suddenly no sunlight
reaching Earth, how would this
affect the ability of plants to
produce carbohydrates?
As we know that plant needs sunlight for performing the process of photosynthesis and by the process of photosynthesis produce food and if there is no sunlight than plant will not be able to produce sunlight and this will affect the ability of plant to produce carbohydrate.
What is photosynthesis?
Green plants contain chlorophyll and they prepare there own food in the presence of sunlight and the process is known as photosynthesis. In the process of photosynthesis light energy converted into chemical energy.
Carbohydrates is defied as that contains biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1. Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle.
[tex]Cn(H2O)n[/tex]is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.Initially the terms carbohydrate was used to describe compounds that have really contains carbohydrates. Because they had simple formula[tex]CH20.[/tex]
Therefore, As we know that plant needs sunlight for performing the process of photosynthesis and by the process of photosynthesis produce food and if there is no sunlight than plant will not be able to produce sunlight and this will affect the ability of plant to produce carbohydrate.
