1. Animal cells do not have a cell wall.
The cell wall in plant cells helps give the cell shape and protection.
2. Mitochondria is the powerhouse of the cell.
The mitochondria gives directions to other organelles. They also create ATP, which gives energy to the cell.
3. The nucleus is the largest organelle in animal cells.
The largest organelle in plant cells is the vacuole, which usually takes up most of its volume. The vacuoles in animal cells are not as big.
4. In plant cells, chloroplast absorbs the sun for photosynthesis.
Chloroplast is very important for plant cells, as photosynthesis is a vital part of survival. It uses the light energy from the sun to create energy.
5. Cells are the smallest unit of life.
Not to be confused with atoms, which are the smallest unit of matter, cells are the smallest unit of life.
6. Humans are made of eukaryotic cells.
Eukaryotic cells are usually animal cells, while prokaryotic cells are usually things like bacteria. Humans are animals.
7. The ribosomes take directions from the nucleus for protein synthesis.
As stated above, the mitochondria will give directions to the organelles, one of them being the ribosomes. They will then use these directions to do protein synthesis.
8. Cells have both DNA and RNA.
DNA will most likely be found in the nucleus of a cell, while RNA will probably be located in the cytoplasm.
9. Prokaryotes do not have a nucleus, along with other organelles.
Prokaryotes do not have membrane-bound organelles, this includes the nucleus.
10. One job that lysosomes have is breaking down macromolecules.
While breaking down macromolecules is one job of lysosomes, they also do things like repair the cell membrane.
How does particle size affect the porosity of an aquifer?u
Answer:
Porosity is influenced by the differences in sizes of the particles in the rock layer. ... This rock layer has high porosity because smaller particles are not present to fill the empty space between particles. So, there is more open space between particles.

Unlike DNA, RNA contains
adenine
uracil
phosphate groups
thymine
(which one?)
Answer:
RNA contains Uracil
Explanation:
DNA's four bases are: Adenine, Thymine, Cytosine, and Guanine.
RNA replaces the Thymine with Uracil, making it the correct choice.

Which type of mutation often has the least effect on organisms' traits (and may have no effect at all)? Nondisjunction Substitution Insertion Deletion
Answer:
The correct answer is - substitution.
Explanation:
Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the DNA or RNA of an organism's genome.
In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.

2.salinity differences between water masses
3.pressure differences between water masses
4.Ekman spiral
Answer:
its the ekman spiral not pressure differences between water masses
Explanation:
Upwelling. Along some coasts, the Ekman spiral causes an upwelling of deeper water to replace the water that has moved offshore. The colder, deeper water is richer in nutrients. These upwelling areas contain some of the richest fishing grounds in the world.

the change in electrical potential that occurs when an impulse passes through a nerve cell
Answer:
The answer to this definition is: ACTION POTENTIAL
Explanation:
Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.
Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.
Passenger airplanes take off in the troposphere but can eventually move into
the stratosphere. The planes may remain in the stratosphere until it is time to
land. Why do you think planes fly in the stratosphere?
it stays there bc there are turbulance which is in the troposphere. The air in the stratosphere has very little water vapor, so there are no interactions with the jet/plane.

Calcium-41 has a half-life of 80,000 years. At the end of 240,000 years,
how much Calcium-41 would remain in a sample initially containing 60
micrograms? *
A 7.5 micrograms
B 60 micrograms
C 15 micrograms
D 30 micrograms
If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as
calcium-41 remaining = initial mass of calcium-41 × (0.5)³.
Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:
60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.
