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:
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 building unit that enters the plant cell organelle membranes?
A -fatty acids
b -ribose sugar
c -simple lipids
d -nucleic acids
Answer:
It's b ribosome sugar
Mark as brainliest
The building unit that enters the plant cell organelle membranes is ribose sugar. When the ribose sugar enters it has to break down into various substituents.
What is the number of carbons in ribose sugar ?The number of carbons in ribose sugar is 5. It is a pentose sugar.
Fatty acids can not pass through the cell membrane as it is very big in size and because of its very larger size it is nearly not possible to enter through the cell membrane.
Simple lipid are present in the cell membrane that is it is following the fluid mossaic model that is the two layers of lipids are present om the cell membrane where the proteins are present on the outer layer. Various types of proteins are present on the membrane.
Nucleic acid is the part of the genetic material where it is present in the DNA,RNA and various proteins.

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.
Ernest would be swimming at 3.25 units on week 10
The explicit formula is given as:
[tex]a_n = a_1 + (n - 1) \times d[/tex]
Also, we have the following parameters
[tex]a_1 =1.0[/tex] -- the initial distance
[tex]d =0.25[/tex] --- the difference between concurrent distances
In week 10, the value of n is 10.
Next, substitute 10 for n in the explicit formula [tex]a_n = a_1 + (n - 1) \times d[/tex]
So, we have:
[tex]a_{10} = 1.0 + (10 - 1) \times 0.25[/tex]
Subtract 1 from 10
[tex]a_{10} = 1.0 + 9 \times 0.25[/tex]
Multiply 9 by 0.25
[tex]a_{10} = 1.0 + 2.25[/tex]
Add 1.0 and 2.25
[tex]a_{10} = 3.25[/tex]
Hence, Ernest would be swimming at 3.25 units on week 10

1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. 100 points!!! Not a scam!
Answer: The sun produces energy to the solar panel the sollaer panel produces energy to my house
Explanation:
The Sun then provides energy to the grass via the photosynthesis process. The rabbit consumes the grass and absorbs its energy.
What is flow of energy?The flow of energy through living things within an ecosystem is referred to as energy flow.
All living organisms can be classified as producers and consumers, and those producers and consumers can be classified further as a food chain. Each level of the food chain is referred to as a trophic level.
The Sun then provides energy to the grass through photosynthesis. The rabbit consumes and absorbs the grass's energy.
Finally, the snake consumes the rabbit and absorbs its energy. Energy travels from the Sun and is consumed by each consumer along the chain.
Thus, this way, energy flows in an ecosystem.

Messages are carried from the eyes to the brain by Question 5 options: nerves muscle light blood vessels.
Answer: Messages are carried from the eyes to the brain by nerves.
(specifically optic nerves)
Explanation:
When we see something, our eyes send messages to our brain through the optic nerves. Each nerve contains around a million long 'wires', called axons, which carry information from ganglion cells in the retina to relevant parts of the brain.
I got it from Goog|e, I hope it helps.
Messages are carried from the eyes to the brain by NERVES. These fibers send sensory messages between the body and brain.
The nerves are groups of fibers that receive and send sensory messages between the body and brain.
The cells that form nerves are called neurons, which use electrical and/or chemical (neurotransmitter) signals to transmit sensory information.
The optic nerve is a specialized nerve that transmits different types of visual sensory information (i.e., brightness, color, perception, contrast, etc).

Explanation:

Xylem and phloem are the types of tissues found in the vascular bundle of plants.
What is the vascular bundle of plants?
In animals, the bloodstream is used to transport nutrients throughout the body. This function is carried delivered via the vascular system, a network of tissues and fibers in plants.
The xylem and the phloem are the two primary tissue types that make up the vascular system. Water and dissolved minerals are distributed upward through the plant through the xylem, first from roots to the leaves. Food is transported from the leaves to the roots through the phloem.
A mature woody stem or root's principal component is made up of xylem cells. They are arranged vertically in the heart of the plant, creating a column that transports water and minerals taken up by the roots up the stem and onto the leaves.
Transporting the food that the leaves have produced downward via the stem is a similar network of phloem cells that line the outside of the xylem.
Therefore, the xylem and phloem are present in the vascular system of plants.

In a controlled environment,
can be used to slow the decay process in foods.
A. gamma rays
B. infrared radiation
C. microwaves
D. x-rays
Given what we know, we can confirm that both gamma rays and x-rays can be used to slow the decay process in foods.
What are gamma rays and x-rays?Both of these are forms of ionizing radiation. Applying these to food is known as food irradiation. What this accomplishes, is that the food that is irradiated will have its chemical bonds altered, slowing the decay process.Therefore, since both gamma rays and x-rays offer ionizing radiation to the food, which affects the chemical bonds and allows the food to have a longer shelf life, we can confirm that they can be used to slow the decay process in foods.
