Answer:
Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.
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.
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 holds amino acid chains within a protein in shape?
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 happens to a monomer once it is used to create a polymer?
A. the monomer can be reused once the polymer is deconstructed
B. the monomer is destroyed
C. The monomer is permanently part of the polymer
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).

Explanation:
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.
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.

Do you think it would be a good idea if all the bumper cars in a ride were to move at the same speed? Use Newton's Law of Motion to support your response.
Answer:
Sorry, I didn´t see this one, maybe you already have the answer, if not: Yes, it is a good idea, because it balances the impact forces of every bumper car.
Explanation:
Yes, it is a good idea, because it balances the impact forces of every bumper car.In this phenomenon Newton's Law of motion has been used to prove this incident.
What is Newton's second law?According to newton second law of motion force is always equal to rate change of momentum. S.I unit of mass is Newton.
So, Force basically depend on two factor i.e mass and velocity
In first case if mass is constant and velocity is variable then
Force = mass × acceleration.
And if mass is variable and velocity is constant then it's called thrust force.
Thrust force = Rate change of mass × velocity.
S.I unit of mass is Newton.
Density has been defined as mass per unit volume it means that mass is present in one meter cube.
S.I unit of density is kg/meter^3.
Mathematically
Density = Mass/Volume.
Momentum has been product of mass and velocity. It is a vector quantity and it's S.I unit kg x meter/sec.
Therefore, Yes, it is a good idea, because it balances the impact forces of every bumper car.In this phenomenon Newton's Law of motion has been used to prove this incident.

Viruses are one of the leading causes of illness in the world
True
False
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.

Answer:
1. In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
a. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
b. In the Calvin cycle (light independent reactions), carbon atoms from CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
2. When transitioning to respiration, photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
3. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
a. Fermentation refers to the metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain.
4. They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
Explanation:
1. A process in which the plants prepares their food from inorganic compounds and light energy is called photosynthesis.
The energy stored in the carbohydrates is used in the preparation of chemical energy.
a. In reactions that use light for the process is called light-dependent reactions. It transpires in the thylakoid organelle of the chloroplast. The light is needed for the synthesis of ATP and NADPH which is a reduced electron carrier.
b. The reactions in which the carbon dioxide is fixed from the carbon source to produce three-carbon sugars is called light-independent reactions. The process of the Calvin cycle transpires in the stroma of the chloroplast.
2. When transpiration changes to the respiratory pathway then glucose is produced during photosynthesis and is used in the process of cellular respiration to produce ATP.
The produced glucose gets converted back into carbon dioxide through the process of expiration.
The water molecules get broken into oxygen during photosynthesis and in another process of cellular respiration, the oxygen combines with hydrogen to yield water.
3. The aerobic process that requires oxygen molecules to break glucose molecules in living organisms to produce ATP and releases energy is called cellular respiration.
The process comprises a reaction between glucose and oxygen to produce carbon dioxide and water.
a. The metabolic process in which the organic molecules are converted to gases, alcohol and acids in the absence of ETC or oxygen is called fermentation.
4. The process of photosynthesis and cellular respiration have similar molecules as:
In the photosynthesis process molecules produced are oxygen, carbohydrates that are high in energy and get converted to glucose or other sugar molecules. In cellular respiration, glucose gets broken into water and carbon dioxide.

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