Ribosomes assemble and join together fatty acids.
True or false?
Answers
Answer:
The job of the ribosome is to make new proteins.
The statement ribosomes assemble and join together fatty acids is false.
What is ribosomes?The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA as well as protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a specific sequence of amino acids that develop into extended chains and fold to create proteins.
What is fatty acids?The building blocks of fat in our bodies and even the food that we eat are called fatty acids. The body converts lipids into fatty acids during digestion so that they can be taken into circulation. A molecule known as a triglyceride is created when three fatty acid molecules are linked together.
Therefore, it can not be said that ribosomes assemble and join together fatty acids.

The DNA of a cell is not
programmed to coordinate the
activities needed to keep a large
cell alive. How does cell division
help the cell avoid DNA overload?
A. When a cell divides there is much less DNA
created than in the large cell, increasing the
overload.
B. Each daughter cell has its own copy of DNA
and can coordinate all the activities of a smaller
cell.
C. Cell division does not help cells to avoid DNA
overload.
Answers
Answer:
the DNA of a cell is not programmed to coordinate the activities needed to keep a. large cell alive. how does cell division help the cell a void DNA overload
The process of cell division helps the cell to avoid DNA overload by the following mechanism:
Each daughter cell has its own copy of DNA and can coordinate all the activities of a smaller cell.Thus, the correct option for this question is B.
What is Cell division?Cell division may be defined as a process through which a parent cell significantly divides into two daughter cells with an identical amount of genetic material.
DNA overload deals with the mechanism of the larger the cell, the greater the requirement for the positioning of the cell's DNA. In order to prevent this mechanism, a cell undergoes the process of division that limits the phenomena of DNA overloading.
This happens with the help of synthesizing two new daughter cells that limit the size of the parental cell.
Therefore, the correct option for this question is B.

What are some disadvantages of fossil fuels?
A Fossil fuels deplete Earth of its historical materials.
B Fossil fuels are nonrenewable and may cause pollution.
C Fossil fuels are relatively cheap to produce and easy to use.
D The use of fossil fuels depletes our forests of resources.
Answers
Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution

The table shows mass and volume measurements in an investigation that involves vinegar and baking soda, both before and after the chemical reaction.
What evidence supports the law of conservation of mass?
The mass remains constant before and after the chemical reaction
The volume of the products is more than the volume of the reactants, so it does not support the law of conservation of mass.
The mass of the gas is more than the mass of the baking soda, so the mass is constant
The density of the products is less than the reactants, so the mass is constant.
Answers
Answer:
mass will be less
Explanation:
A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less

*For the second blank it's either Genotype or Phenotype!*
Answers
Genotype- The combination of alleles
Phenotypes- The physical appearance of the alleles
Genes- The stuff in DNA that the genotypes are in
Traits- Stuff you’ve inherited and all
The specific combination of alleles an organism has is called its genotype which affects the organism's phenotype.
What do you mean by Alleles?Alleles may be defined as one of two or more DNA sequences occurring at a particular gene locus.
Genotype may be defined as the ultimate combination of alleles of those genes which are selected for studies.
The Phenotype may be defined as the expression of a genotype in the form of a trait. It is the morphology or physiology which comes due to a combination of alleles.
Therefore, the specific combination of alleles an organism has is called its genotype which affects the organism's phenotype.

Why must the cell make sure it duplicates its
organelles and DNA before mitosis occurs?
Answers
Explanation:
Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.

10-15 Facts about cells
Answers
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.
