Biology

1 answer:

Delvig [45]3 years ago

5 0

Answer:

The answer is

D) 2.98 x 10^11

Explanation:

To be written in scientific notation, the first number or the number being multiplied by 10^# must be written like this Ex. 1.0 2.0 3.0 etc. In other words it must have one and only one digit to the left of the decimal and answer choice D is the only answer choice that meets the criteria.

g During the G2 stage of interphase, ___ does not occur. A. organelle replication B. DNA growth C. protein replication D. cell g

ArbitrLikvidat [17]

Answer: DNA growth does not occur

Explanation:

Here, the cell has grown, the DNA has been replicated (this takes place in the S phase of interphase) and its almost time for the cell to divide. Basically, what occurs during the G2 phase (Gap 2 phase of interphase) includes duplication of all proteins and organelles needed later during the process of cell division. Some of these includes assembly of microtubles will later for the spindle structure that that helps in the separation of chromosomes during the M phase but these are produced during the G2 phase.

The cells also continue to increase/grow in size and the volume of the cytoplasm also increase in this phase. There is also a checking where the cell needs to check for the structures and components and to also ensure that they are all present

Joanna woke up complaining of ear pain. The physician assistant observed that her temperature was 39 C and diagnosed a bacterial

Elanso [62]

Joanna'a therapy is antibiotic therapy.

Antibiotic therapy is the therapeutic way to overcome an infection using one or more anti-infectious drugs, belonging to the class of antibiotics, and whose activity is exerted against the bacteria causing this infection. It could also be used to prevent superinfection (for example after bronchitis, cold, flu, viral infections or ear infections) or to reduce the risk of infection before surgery.

DNA replication of chromosomal DNA in a cell requires all of the following, EXCEPT A) DNA polymerase B) primase C) helicase D) R

Viktor [21]

Answer:

The correct answer is D)RNA polymerase

Explanation:

In DNA replication many enzymes and proteins are required to replicate a DNA template. For initiation of DNA synthesis the two DNA strands must be separated which is done by helicase.

Then primase adds short nucleotide sequence and initiate DNA replication. After that DNA polymerase acts and adds nucleotide at the 3' end of growing DNA strand. Ligase is the enzyme that joins the two Okazaki fragments that are created in the lagging strand.

RNA polymerase is not required in DNA replication and it works in transcription therefore the correct answer is RNA polymerase.

identify the types of questions that interest behavior geneticists, and describe the elements of heredity: chromosome, dna, gene

baherus [9]

The interaction between genetics and environment and how this affects behavior, resulting in individual variances, is of particular interest to behavior geneticists.

The environment in this context refers to every external, nongenetic component of our life, including prenatal nutrition and the people and objects in our immediate surroundings.

Chromosomes:

Each of our cells contains 46 chromosomes, 23 from our mother and 23 from our father. Chromosomes are complicated, spiraling molecules formed of DNA that resemble threads and contain genes.

DNA:

We have over 30,000 genes, which are DNA segments that, when activated (expressed), serve as templates for the synthesis of different protein molecules, which serve as the foundation for our physical and behavioral growth.

Genome:

The entire collection of instructions for creating an organism, included in all of its chromosomal genetic material, is called an organism's genome.

Gene:

Combinations of mutations at certain gene locations serve to distinguish us from one another. The majority of human features are not controlled by a single gene acting alone, but rather by a number of genes working together.
