A bacterium, containing one circular DNA chromosome, undergoes four rounds of replication. How many new strands of DNA would result?

Answers

Answer 1

Answer:

The correct answer is 32 strands.

Explanation:

In bacterium, DNA replication is bidirectional which means it takes place in both directions. The origin of replication starts the replication, it is a specific sequence of nucleotides. Each strand of circular DNA acts as a parent strand to replicate its complementary new strand, resulting in two new DNA strands, one parent strand, and one new synthesized strand. So after the first round of replication, there are 4 strands formed.

Similarly, during the second round of replication each of the four strands will be synthesized lead to a total of 8 strands in the same manner. So by the same process in 3rd round will lead to 16 new strands and by the fourth round of replication 32 strands will be synthesized.

Thus, the correct answer is 32 strands.

A student states that exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time. An experiment is carried out to test this hypothesis. One group of ten students sits quietly before squeezing a clothespin as many times as possible during a one-minute interval. A second group of ten students does 25 jumping jacks before squeezing a clothespin as many times as possible during a one-minute interval. What is the independent variable?

Answers

Answer:

EXERCISE

Explanation:

In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.

In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).

The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.

Cell is the small unit of all living organism, observed in animal, plant, microbes etc; cells are unicellular in nature like bacteria cell, where as some are multicellular in nature like all higher eukaryotic organisms such as plants and animal cell.

The simplest form of cells are prokaryotic cells have a cell membrane, cell wall and cytoplasm where all of the metabolic processes occur, ribosomes needed for protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.

The eukaryotic cells contain a complex organization where it contain cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum , smooth endoplasmic reticulum for lipids, Golgi apparatus responsible for protein sorting and exporting.

It has mitochondria power house house of the cell, a cytoskeleton responsible for structure and passes information, and lysosomes or peroxisomes for waste digestion, vacuoles for water storage, chloroplasts for photosynthesis.

Choose THREE reasons why less energy is passed from one trophic level to the next

Answers

Answer:

As metabolic heat makes energy be lost after an animal is consumed the food chain loose energy

Explanation:

Answer:
Key Points
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels. A food chain can usually sustain no more than six energy transfers before all the energy is used up.

Whats the difference between bacteria cells, and blood cells?

Answers

Answer:

recent study out of the Weizmann Institute in Israel states that the number of bacteria may actually be very similar to the number of human cells in the body.

While this results in about 1.3 bacterial cell per human cell, the numbers may vary significantly from person to person and could change significantly with each defecation. They estimate that the range of bacterial cells goes from about 30 to 50 trillion in each individual. Women may also have a higher ratio of bacterial cells than human cells because they have fewer human cells, specifically red blood cells.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must do, especially the actual experiment part. You must also list the "controlled variables", the "independent variable", and the "dependent variable

Answers

Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.

Explanation:

We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.

Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:

1. We can apply Vitamin C in a form of solution on the ashy skin.

2. Observe the changes on the skin directly and apply for 2-3 times in a day.

3. Observe the changes on the skin after a week.

What is a rule for making a neutral atom which has no charge?​

Answers

A neutral atom which has no charge. The amount of electrons and protons must be the same. ... The amount of the electrons have to be more than the amount of the protons. Rule #4: Mass. The number of electrons do not affect the mass; however, the more protons and neutrons you add to the atom, the bigger the mass gets.

The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).

Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.

There are three conditions possible:

The neutral atom that has no charge - The number of electrons and protons must be the same.

                            E = P

A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.

                             E < P

A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.

                           E > P

Thus, the correct answer is - Electron (E) = Proton (Protons).
