bacteria, plants, mitochondria
bacteria, animals, nuclei
protists, bacteria, viruses
protists, bacteria, plants

Answers

Yes, mitochondria and nuclei are both organelles inside of eukaryotic cells specifically. Viruses are not considered to be composed of cells. So, protists (eukaryotic), bacteria (prokaryotic), and plants (eukaryotic) are all composed of cells. (Your last option is correct), hope this helps!! :)

Protists, bacteria, and plants all are the organisms which are composed of cells. The cell is the basic unit of life. Thus, the correct option is D.

What are cells?

The cell is basic structural and functional unit of life. Cells consist of the living matter which is known as protoplasm, a layer which encloses the living matter which is called as cell membrane or plasma membrane.

All the living organisms are made up of cells. It is the defining characteristic of living organisms. Protists, bacteria, and plants all are composed of cells. Protists are the single-celled eukaryotic organisms and plants and animals are the multicellular eukaryotic organisms.

Mitochondria and nucleus are the cell organelles which are responsible for the production of energy and contain the genetic information, respectively. Viruses are acellular organisms as they are not made up of cells but contains the genetic material within a protein coat.

Therefore, the correct option is D.

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.

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

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).

Answers

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.

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.

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.

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.
