A. Mitosis is the correct answer.

DNA replication occurs in the two major types of cell division: mitosis and meiosis.

Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.

Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).

Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.

Why are some of Carl Linnaeus’s classifications of organisms incorrect?. A.Linnaeus did not study the anatomy of organisms.. B.L
Soloha48 [4]

Answer;

D) Linnaeus primarily used physical characteristics.

Explanation;

-Carolus Linnaeus developed naming system that is still used today, called binomial nomenclature. He is known as the Father of Taxonomy,  which is the system of classifying and naming organisms.  

-Among is contribution is the development of a hierarchical system of classification of nature, which includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.

-However, some of Carl Linnaeus's classifications of organisms were incorrect because Linnaeus primarily used physical characteristics.

What is the correct order of processes involving the movement of oxygen from the environment to mitochondria in vertebrates?
Nuetrik [128]

Answer:

a.) ventilation, circulation, cellular respiration

Explanation:

a.) ventilation, circulation, cellular respiration

b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface

c.) ventilation, diffusion in tissues, circulation

d.) circulation, cellular respiration, diffusion in tissues

e.) circulation, ventilation, cellular respiration

Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.

Help me with this please
daser333 [38]

Answer:

1. b

2. a

3. a

4. b

5. b

6. a

7. a or b (they're the same)

(Punnett square and chart attached)

Explanation:

1. The father is a non-roller, as was given in the question. Remember that a phenotype is the physical trait displayed by an organism.

2. In order for the father to be a non-roller, the recessive non-roller allele would have to be expressed. In order for this to happen, he would need two recessive alleles.

3. The gene for tongue rolling is dominant, so if the mother is heterozygous (she has one dominant allele and one recessive allele), then she will be a tongue roller.

4. The mother has a dominant allele and a recessive allele.

5. 50% of the offspring have the Rr genotype and 50% have the rr genotype. This means that there is a 50% of having a tongue-rolling child and a 50% chance of having a non-rolling child.

6. Because the possibility of the offspring having either genotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.

7. Because the possibility of the offspring having either phenotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.
