Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:
1. sister chromatids / centromeres:
2. mother cell / daughter cell: Identical
3. interphase/ cell division:
4. DNA / chromosome:
5. mitosis / cytokinesis:​

Answers

Answer 1

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.

What is the difference between weathering and erosion? (Site 1).

Answers

Answer:

Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.

Which statement best explains why the population stabilized and why?!

A population of chipmunks migrated to an environment
where they had little competition, Their population quickly
increased but eventually stabilized as shown in the graph.

A. Interbreeding between members of the population increased the mutation rate.

B. A predator species came to the area and occupied the same niche as the
chipmunks

C.
The population size became limited due to factors such as availability of food.

D. An increase in the chipmunk population caused an increase in the producer
population.

Answers

Answer: C. The population size became limited due to factors such as availability of food.

Explanation:

Out of all the choices, C is the most likely to happen since more often then not, food runs out because a species has too many members. C is an example of the environment’s carrying capacity limiting the chipmunk species.

Since we are not told if the chipmunk population is really small, interbreeding may not happen. Predators hunt prey, not eat fruits like chipmunks do (I’m assuming what chipmunks eat.) If there was a predator species that came in, they would hunt the chipmunks instead of competing for the same resources. D just doesn’t make much sense in my opinion because that wouldn’t limit the chipmunk population.

The population size became limited due to factors such as availability of food in the chipmunks. Thus the correct option is C.

Why the population size become limited?

The population size become limited because of carrying capacity. It can be defined as a species' average population size in a particular habitat.

The chipmunks species population size is limited by environmental factors like adequate food, water, shelter, and mates. If these needs are not met, the population will decrease until the resource resile.

Both cell types undergo cell division by mitosis. Therefore, option (C) is correct.

What are eukaryotic and prokaryotic cells?

A nucleus and other membrane-bound organelles are exclusively found in eukaryotic cells, which is the main distinction between prokaryotic and eukaryotic cells. Prokaryotes and eukaryotes, respectively, are made up of prokaryotic and eukaryotic cells. Eukaryotes often have several cells, but prokaryotes are invariably unicellular. Eukaryotic cells are also between 100 to 10,000 times bigger and more complicated than prokaryotic cells.

Prokaryotic DNA is kept in the cytoplasm, while DNA in eukaryotes is kept in the nucleus. Additionally, double-stranded chromosomes that are compressed by histones are where eukaryotic cells store their DNA. Prokaryotic organisms, on the other hand, only contain one basic circular chromosome and a variety of plasmids, which are tiny DNA rings. In comparison to prokaryotic cells, the DNA of eukaryotic cells contains a higher percentage of non-coding DNA and proportionately less coding DNA.

Answers

Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.

what was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?

Answers

Explanation:

DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

[tex] \mathbb \fcolorbox{green}{red}{ STAY \: STRONG}[/tex]

[tex] \mathfrak \fcolorbox{green}{red}{BE \: BRAINLY }[/tex]

In the DNA  structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

What is Hershey and Chase experiment?

Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.

They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.

Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNA

Next, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).

This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.

Thus, in the DNA  structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

Phytohormones are responsible for the movement of plant towards stimulus. Auxin is the main phytohormone responsible for gravitropism and phototropism of plants.

What is Plant Movement?

Plants are immobile however different parts of the plant show movements in response to the stimulus in the environment. The chemicals present in the plant body which are responsible for these movements are called phytohormones or plant hormones.

Auxins are the main hormones responsible for the cell elongation in plants.  Auxins are responsible for the phototropism (movement of plant parts in response to light) and gravitropism (movement in plants in response to gravity).

Roots of a plant grow downward and exhibit positive gravitropism whereas stems on the other hand, exhibit negative gravitropism since they grow upwards and against the gravity. If you place a plant on its side or even upside down, the stem will curve its way up in response to gravity and auxin is responsible for this movement.
