B. Water is nonpolar and oil is nonpolar therefore the substances won't mix.
C. Water is nonpolar and oil is polar therefore the substances will not mix.
D. Water is polar and oil is nonpolar therefore the substances will not mix.
Answer:
Water is polar and oil is nonpolar so the substances won't mix.
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.

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

start superscript, 1, end superscript A cell deep inside your body—in one of your bones, say, or in your liver—can’t get the nutrients or oxygen it needs directly from the environment.
How, then, does the body nourish its cells and keep itself running? Let's take a closer look at how the organization of your amazing body makes this possible.

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.

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

What name is given to a factor which is preventing any increase in photosynthesis?
Answer: A limiting factor
Explanation: A limiting factor is simply anything in short supply that prevents photosynthesis occurring at its maximum rate. Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
Any factor that prevents any increase in photosynthesis is known as a LIMITING FACTOR.
In photosynthesis, a limiting factor is defined as a factor/agent that constrains photosynthetic activity.The most important factors capable of limiting the rate of photosynthesis include light, carbon dioxide (CO2) level and temperature.For example, photosynthesis cannot take place without light, which is absorbed by chlorophyll pigment molecules to start photosynthesis.In conclusion, any factor that prevents any increase in photosynthesis is known as a LIMITING FACTOR.

Explanation:
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.
