1. Describe cell differentiation and include any environmental factors that play a role in gene regulation. 2. Explain the types of cells produced by meiosis. Include in your explanation the number of daughter cells produced, the number of chromosomes in each and whether they are diploid or haploid.

Answers

Answer:

1. Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens.

2. Gametes or sex cells are produced in meiosis and they have haploid number of chromosomes. In humans, the haploid number of chromosomes is 23 chromosomes.

Explanation:

Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. During the initiation of cell differentiation, transcription factors activate only  the genes to be expressed. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, and the presence of mutagens(factors that cause mutation).

Differentiation occurs in zygotes numerous times resulting in the formation of a fully developed organism. Also in unspecialized cells known as stem cells, differentiation occurs leading to the formation of various cells of the organs and tissues of the body.

2. Meiosis is a type of cell division in which gametes or sex cells are produced. A single cell divides twice producing daughter cells with half the number of chromosomes present in the parent cell. In humans, the chromosome number is 46. After, meiosis, the haploid number of chromosomes produced is 23.

What happens to a substance when it is heated?

a
Thermal energy is decreased
b
Potential energy is increased
c
Kinetic energy is increased
d
It does not change its physical shape

Answers

Answer: C

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster:  the space between atoms increases:   The motion and spacing of the particles determines the state of matter of the substance:  The end result of increased molecular motion is that the object expands and takes up more space.

Cytoplasm is liquid that keeps the cell _________.
A: moving
B: airy
C: solid

Answers

Answer:

I think the cytoplasm keeps the cell solid.

Explanation:

Cytoplasm keeps all the cellular organelles suspended. The cytoplasm helps to keep them in place. It is also the site of most metabolic activities in the cell, and it allows materials to pass easily throughout the cell.

The cytoplasm is the liquid that keeps the cell solid. The correct option is C.

What is cytoplasm?

The cytoplasm is a liquid that is filled inside the cell. Between the cell membrane and the nucleus, there is a jelly-like fluid called cytoplasm. It facilitates material exchange and storage among cell organelles.

Cytoplasm helps the cell to stay still and rigid. It places all the cell organelle into a fixed place and the transfer of ions and molecules is also done by the cytoplasm. It is made up of water, salts, and other various material.

They help in the coming in of the materials and going out of the materials. They also protect the cell from shock and other invasive, they make the cell rigid and flexible and also protect recall from each other.

Thus, the correct option is C. solid.

What holds amino acid chains within a protein in shape?​

Answers

Answer:

Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they serve as the catalysts for virtually every biochemical reaction that occurs in living things. This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures.

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.

What might happen to a cell if its cell membrane fails to function properly?

Answers

Answer:

If cell membrane fails to function then the cell will not be able to perform its task properly. The organelles will stop working which means no more protein created, no more energy production in the mitochondria and no material comes in and out of the cell. Eventually the cell will die.

Your welcome

Answer:

If the cell membrane is unable to do its job properly, this can cause the cell to stop working properly. If many cells have bad cell membranes, the disease can affect an entire organ or even the whole body. In many of these cell membrane diseases, proteins within the cell membrane don't transport materials properly.

Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation could have on an individual's traits.

Answers

Answer:

Explanation:

Three ways in which mutation could occur are

1) If an error occurs during DNA replication and it's not corrected in time by DNA polymerase.

2) If there is a deletion of a base(s) in the sequence of the DNA. The deletion of a DNA nucleotide/base could also cause a mutation as that could affect the formation of an enzyme or protein useful in building and/processing certain body parts/processes.

3) Thymine dimerization: Thymine dimers are mutations that prevent DNA from replication or even transcription hence preventing a cell from undergoing division (hence causes cancer). They are formed when covalent bonds are formed between the bases of a DNA sequence (somewhere around the carbon-carbon double bond).

The two effects are

1) It could cause cancer as described in (3) above (in the case of thymine dimer)

2) It could lead to deformity in an individual because of the gene that is supposed to code for the last finger has a base deletion, that could eventually lead to the absence of that finger or a shorter or "strange" finger.

Viruses are one of the leading causes of illness in the world

True
False

Answers

Answer:

True

Explanation:

Answer:

False, but be sure you read what follows.

Explanation:

False: Heart disease and Most Cancers are not viruses. Or at least as far as I know. However complicating the issue is the fact that after a viral infection, heart disease can develop.

Cancer is another example, and the answer again is not black and white. 16% of all cancers can trace their beginnings to a bacteria or virus. That leaves 84% whose beginnings are not that clear.

The question is not black and white. I'd be careful how you think of it. If something is a complication, is that a direct cause? I still think the answer is false,  but don't be surprised if your instructor disagrees. Move on to something a little less black and white.

B. the monomer is destroyed
C. The monomer is permanently part of the polymer

Answers

The answer is A it can be reused.

The monomer can be reused once the polymer is deconstructed. So, the correct option is (A).

What is Monomer?

A monomer is defined as a molecule which can react with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.

These are described as atoms or small molecules which bond together to form more complex structures known as polymers. There are four main types of monomer which include sugars, amino acids, fatty acids, and nucleotides.

Monomers can also be reused again when the polymer is deconstructed.

Thus, the monomer can be reused once the polymer is deconstructed. So, the correct option is (A).
