Answer:
Since every person inherited DNA from their parents, who inherited it from their parents, and so on, a person's DNA is made up of the DNA of their ancestors. If you and another person both have the same ancestor, there's a chance that you both inherited some of the same DNA.

An event that restricts the size of a population such as weather events like drought or flood is likely a
1)density dependent limiting factor
2)density independent limiting factor
3)immigration
4)emmigration
Answer:
The correct answer is - 2) density-independent limiting factor.
Explanation:
Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.
Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.
Drought affects the size of the population by increasing competition in the ecosystem for resources.

Answer: a
Explanation:
A population of rabbits in an ecosystem has genetic variation in fur thickness. Some rabbits have thick fur and others have thin fur. Due to changes in the environment, the average temperature of the ecosystem is steadily increasing.
How will this environmental change likely affect the rabbit population over time?
A. Rabbits with thick fur will become more common in the population because thick fur will be a favorable trait in this changing environment.
B. Rabbits with thin fur will become more common in the population because these rabbits are more likely to survive and successfully reproduce.
C. Rabbits with thick fur and thin fur will become equally distributed because all rabbits in the population will successfully reproduce.
D. Rabbits with both fur types will increase in the population because the temperature change will cause the population of rabbits to expand.
Answer:
B
Explanation:
Thin fur is better for warmer weather, so the rabbits with thinner fur won't over heat in the warming weather.
The population of rabbits n the genetic ecosystem has thick fur and others have thin fur, due to the changes in the climate avg temperature of the ecosystem is steadily falling.
Looking at the situation and adaptive powers or abilities of the animals the thick fur will survive longer than those of the thin fur as the temperature of the place is declining.Hence the option A is correct.

What is the law of dominance
What is the law of segregation
Answer:
Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. ... The recessive allele will remain “latent,” but will be transmitted to offspring by the same manner in which the dominant allele is transmitted.
What is the law of segregation- The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele. Both alleles will have the same chance of ending up in a zygote. In sexually reproducing organsisms, the genome is carried in two identical copies. A copy was inherited from each parent, in the form of a gamete

A vesicle is used for protein
production
True
False
will give brainliest! :)
Answer:
True
Explanation:
A vesicle is used in the production of proteins in the cell. The given statement is true. Proteins are produced in the endoplasmic reticulum and processed and packaged in the vesicles.
What is Protein production?A protein is synthesized in the ribosomes of rough endoplasmic reticulum. These proteins are translated from the mRNA which contains the genetic sequence that codes for specific proteins.
The proteins synthesized in ribosomes will then undergo post-translational modifications in the golgi apparatus, and are transported in the form of vesicles to their particular destinations.
The vesicles act as containers which carry the proteins from the organelle where the proteins are produced (rough endoplasmic reticulum) to the destination i.e., plasma membrane.

Two processes needed for survival of life on this planet are cellular respiration and photosynthesis. How are cellular respiration and photosynthesis mutually dependent ?
A. Photosynthesis releases energy and cellular respiration stores energy.
B. Photosynthesis releases carbon dioxide and cellular respiration releases oxygen.
C. Photosynthesis removes oxygen from the atmosphere and cellular respiration replaces it.
D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
???
Photosynthesis and respiration depend on each other and complement themselves. Option D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
Why are Photosynthesis and respiration complementary processes?Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria.The photosynthetic process needs solar radiation to produce organic compounds, while the respiration process needs the organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compounds, while respiration transforms organic compounds into CO₂.In the process of photosynthesis, it occurs a release of oxygen, which is then used during the respiration process. Both processes produce energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products are carbohydrates and oxygen.
The correct option is D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.

Which of the following occurs in lactic acid fermentation?
a. Electrons pass through the electron transport chain.
b. Oxygen is consumed.
c. Lactic acid is converted into pyruvic acid.
d. NAD+ is regenerated for use in glycolysis.
Answer:
D
Explanation:
Thats all i know hope it helps
Lactic acid is created when pyruvate is reduced to make it, while NAD+ is created when NADH is oxidized. Reducing pyruvate to lactate requires a proton from NADH and electrons from the molecule. Thus, option D is correct.
What is the role of Lactic acid fermentation?Anaerobic respiration occurs when human muscle cells do not receive enough oxygen. So, the fermentation of lactic acid results in the production of energy molecules. The result of this process is lactic acid.
Oxidize electron transporters to allow for glycolysis re-use. Without the aid of oxygen, fermentation enables cells to generate chemical energy from the breakdown of sugar, such as glucose.
Therefore, in lactic acid fermentation, NAD+ is regenerated for use in glycolysis.

To calculate the Percent of Cells in each phase, use the number of cells counted in that phase divided by the total number of cells and multiply by 100. Round to whole numbers.
Answer:
Yes.
Explanation:
Yes, to calculate percentage of cells in each phase, we will divide the total number of cells in each phase of mitosis or meiosis by the total number of cells, and then multiply by 100 to get the percentage of cells in each stage. In that way we can find out that how many cells present in which phase of the cell cycle. Most of the cells about 80 to 90 % of cells spent their time in interphase.

what develops as the dna molecule unzips with replication occurring on both strands at the same time
Answer:
The double-stranded parent DNA molecule gets separated and provides two template DNA strands for daughter strands synthesis. Enzyme DNA polymerase adds nucleotides complementary to template strands and synthesize daughter strands.
Explanation:
Answer:
The a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.

A. Polymer
B. RNA enzyme
C. Gene
D. Double helix
Answer:
C. Gene
Explanation:
Hope this will help
A unit of hereditary information consisting of a particular nucleotide sequence in DNA would be called a gene.
The basic unit of hereditary is the gene. Particularly, genes are located on chromosomes that are made of DNA. In order words, genes make up the DNA, while DNA makes up the chromosomes.
In the DNA, genes exist as genetic codes with each code specifying a particular amino acid. In order for genes to be expressed, the information on DNA are first transcribed to mRNA and the genetic codes are then translated to their respective amino acids linked together by peptide bonds.
