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.

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

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
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.

Answer:
False
Explanation:
the Coral is not a producer, but rather a secondary consumer, in order to be a producer of an organism must be able to carry out photosynthesis.
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.

Organelles are structures within the cell that perform important functions. Which of the following correctly matches the
organelle with its relationship to the whole cell?
Answer:
mitochondria: powerhouse of the cell
Ribosomes: the places where proteins are synthesized in our cells.
nucleus houses DNA;controls cell
Vacuole: holds waste and fluids from cell
Ribosomes: tiny organelles that contain RNA and specific proteins within the cytoplasm.
Explanation:
Organelles make up the subunits of a cell. There are numerous each with their own function.
There are various cell organelles that play an essential function these are as follow:
MitochondriaNucleusChloroplastEndoplasmic reticulumGolgi bodiesRibosomePeroxisomeWhat is the different role of cell organelles?Mitochondria: Generates energy (ATP) for the biochemical reaction.
Nucleus: Responsible for the synthesis of mRNA, rRNA, tRNA and DNA.
Chloroplast: responsible for Photosynthesis by using sunlight in plant cells.
Endoplasmic reticulum: carry Protein(RER) and lipid synthesis(SER).
Golgi bodies: play role in protein sorting, transporting and trafficking.
Ribosome: two types of ribosomes are present in the cell-free ribosome and membrane-bound ribosomes, responsible for the synthesis of protein.
Peroxisome: play role in fatty acid oxidation and metabolism.
Thus, all these organelles play important functions in cells.

A. Water is polar and oil is polar therefore the substances will not mix.
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.

How can someone change the salinity of water, without adding or removing salt?
Answer:
I'm not as sure about this answer, but I think you can just boil it!
Explanation:
By boiling down any salt water, it lessens the salinity levels, and makes it more consumable and clean to drink. That's why they say to do that if you are on a deserted island and have no clean water!

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.
