A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

What is a Renewable resource?

A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.

Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.

Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

PLEASE HELP!!!!! Describe in detail the process of dna replication

Answers

Answer:

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Answers

I think all the mice had brown fur due to epistasis

Explanation:

The expected results would be 50% black and 50% brown and the ratio could be 2:2.  But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.  

The Punnett square to find the expected ratio of black to brown mice pups is to be considered when all the mice had brown fur because to epistasis.

Completion of the Punnett square:

The expected result should be 50% black and 50% brown and the ratio should be considered as the 2:2.

Answer:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.

Answers

Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,

What is the law of dominance



What is the law of segregation

Answers

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

Answers

Answer:

The correct answer is - The growth and tissue repair are the major purpose of mitotic cells in multicellular organisms.

Explanation:

The purpose of mitotic cell division in multicellular organisms can be understood by the three points:

1. somatic cells divide through mitotic cell division.

2. Every multicellular organism shows growth and develop with time in size

3. Every cell of the body is repaired with the help of the mitosis that replaces the damaged cell with the new cell.

Single-celled eukaryotes show asexual reproduction by binary fission which is a form of mitosis.

swimming. These are examples of -
F: analogous structures
G: homologous structures
H: vestigial structures
J: endosymbiosis

Answers: G

Answers

Answer:

Your answer is most likely G), so you are correct.

These are the example of Homologous structure. So, the correct option is (G).

What are different types of structures?

Homologous structures are similar in structure and location, but perform different functions, resulting in divergent evolution. For example, An arm of a human, the leg of a dog or a flipper of a whale are all homologous structures.

Analogous structures are similar in function but have different origins and structures resulting in convergent evolution. For example, from wings in birds, bats and insects to fins in penguins and fishes are all analogous structures.

Structures with similar anatomy, morphology, embryology, and genetics, but dissimilar functions are known as homologous structures, while structures that are superficially similar but perform the same physiological function are referred to as analogous structures.

Thus. these are the example of Homologous structure. So, the correct option is (G).

Answers

Answer:

The number of individuals that must exist for a species to continue

Explanation:

I just had it on a quiz. Can I have brainliest?

The critical mass of a species is the number of individuals that must exist for a species to continue. Therefore, the correct option is C.

What is the critical mass of a species?

The critical mass of a species refers to the minimum number of individuals that are required for a population to maintain its viability and continue to survive and reproduce in a given environment. This is also known as the minimum viable population (MVP) size.

The concept of critical mass is important in conservation biology because small populations are often more vulnerable to extinction due to genetic factors, environmental fluctuations, and other factors.

Therefore, understanding the critical mass of a species is significant for determining appropriate conservation strategies and protecting endangered species. Therefore, the correct option is C.
