Answer:
Incomplete dominance, 0%
Explanation:
In incomplete dominance, the phenotypes of the dominant and recessive genes are blended. In this case, red and white are blended to create pink.
A Punnett square can be used to determine the phenotypes of the offspring of a white flower and a pink flower. In this case, we'll let "R" represent a gene for a red flower and "r" represent a gene for a white flower.
r r
R Rr Rr
r rr rr
The "Rr" genotype would result in a pink flower, and the "rr" genotype would result in a white flower. It is impossible for this cross to result in a red flower.

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.
Explanation:
(please help) if a particular fossil was found in rock layer f and another fossil was found in rock layer m on the right side of the picture, which one would be older? why?
Answer:
The particular fossil "f" found on the left side is older because it is deeper than the fossil "f" on the right side. Meaning it's been in the ground longer than the other.
Explanation:
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.
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 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.

Why are the vacuoles in plant cells different than the vacuoles found in animal cells?
A Plants need more energy than animals do.
B Plants need to store more food than animals do.
C Plants need to produce proteins, while animals do not.
D Plants need to move materials in and out of cells, while animals do not.
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.
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 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.

Answer:
Reactive
oxygen

Ores
Unreactive
Pure
Silver
Explanation:
The activity series shows the order of reactivity of metals. Metals that are high up in the series are highly reactive. These highly reactive metals will not exist alone in the ground. They combine with elements such as oxygen, sulphur, etc to form ores.
Other metals that are found much lower in the activity series are largely unreactive. They exist in the ground as pure metals, examples include silver and gold
