What are 3 differences between DNA and mRNA (messenger RNA)
Answer:
DNA is made up of deoxyribose sugar while mRNA is made up of ribose sugar.
DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base.
DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis.

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.
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.

how is starch in the sweet potato is produced from carbon dioxide in the air.
Answer:
In photosynthesis, plants use light energy to produce glucose from carbon dioxide. The glucose is used to make cellulose fibers, the structural component of the plant, or is stored in the form of starch granules, in amyloplasts. Toward the end of the growing season, starch accumulates in twigs of trees near the buds.
The specific combination of alleles an organism has is called its ____ which affect(s) the organism's ____.
A. Phenotype
B. Genes
C. Genotype
D. Traits
*For the second blank it's either Genotype or Phenotype!*
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.

Identify the following types of mutations that have occurred in the DNA sequences shown below. (The different types of mutations are: insertions - where an extra sequence of DNA has been inserted in an area where it should not exist; substitutions - Where nucleotides have been swapped out for different, incorrect nucleotide bases; and deletions - where a section of DNA has been deleted and removed from the original sequence.)
Original DNA Sequence: CCT GAT GCG AAG TTA TCA GTA CCA
Mutated DNA sequence 1: CCT GAT GCG TTA TCA GTA CCA
Answer:
Mutated DNA Sequence 2: CCT GAT GCG AAG CCC TTA TCA GTA CCA
Answer:
Mutated DNA Sequence 3: CCT GAT GCG AAG TTA TGA GTA CCA
Answer:
Answer:
CCT GAT GCG AAG TTA TGA GTA CCA?
The types of mutation with respect to the mutated DNA sequences are as follows:
Mutated DNA sequence 1: CCT GAT GCG TTA TCA GTA CCA: Substitution and deletion. Mutated DNA Sequence 2: CCT GAT GCG AAG CCC TTA TCA GTA CCA: Insertion. Mutated DNA Sequence 3: CCT GAT GCG AAG TTA TGA GTA CCA: Substitution. What is Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism. An organism that undergoes an event of mutation is known as a Mutant. The agents of mutation are known as mutagens.
Substitution mutation is where nucleotides have been swapped out for different like incorrect nucleotide bases. Insertion mutation is where an extra sequence of DNA has been inserted in an area where it should not exist while deletion mutation is where a section of DNA has been deleted and removed from the original sequence.

Which of the following habitats has a water level that changes with the tide?
O salt marsh
O abyssal zone
O deep oceanic layer
O sublittoral zone
Answer:
The correct answer would be Salt Marsh
Explanation:
Hope this helps <3
The habitat that has a water level that changes with the tide is a salt marsh. Therefore, option (A) is correct.
What is a salt marsh?There is a form of coastal wetland known as a salt marsh that gets inundated and dried out by the saltwater that comes in with the tides. The arriving and outgoing tides can cause the water level in a salt marsh to fluctuate by several meters throughout the course of a single day.
This results in the formation of a one-of-a-kind habitat that has become acclimated to the fluctuating levels of water, with plants and animals that are able to endure being exposed to air and saltwater at various periods during the day. On the other hand, the abyssal zone, the deep oceanic layer, and the sublittoral zone can all be found in deeper seas and are not influenced by the tides.

10-15 Facts about cells
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.
