Explain what factors can lead to genetic
variation within a population.
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Animal and plant cells have all of the following EXCEPT
A. chloroplasts to carry out photosynthesis.
B. vacuoles to store water and nutrients.
C. a nucleus with DNA to replicate cells.
D. mitochondria to form chemical energy.
Answer:
The answer is A, chloroplasts to carry out photosynthesis.
Explanation: The animal cell does not have photosynthesis.
Animal and plant cells have all of the following EXCEPT - A. chloroplasts to carry out photosynthesis.
Chloroplasts are the cellular membrane-bound organelle that is specific to the plant cell and does not found in animal cells. Chloroplast carried out the process known as photosynthesis.
In these organelles, photosynthetic pigment chlorophyll found that captures the energy from sunlightMitochondria are also membrane-bound organelle found in all eukaryotic cells including animal and plant cells to carry out cellular respiration.The nucleus is also present in both types of the eukaryotic cell, plant and animal cell that stores genetic material.Vacuoles are present in the eukaryotic cells, to store water and nutrients.Thus, Animal and plant cells have all of the above EXCEPT - A. chloroplasts to carry out photosynthesis.

The diagram compares diffusion of sugar molecules and osmosis. Explain the difference between osmosis and diffusion in cells
Answer:
What is the difference between osmosis and diffusion? Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. The process by which water molecules are able to diffuse through the cell membrane.
Explanation:
Diffusion and osmosis involves the movement of materials from one region another. The main difference between osmosis and diffusion is that osmosis requires a semi permeable membrane.
The movement of materials always occur in cells. This movement could occur by;
Active transportOsmosisdiffusionThe difference between osmosis and diffusion is that, diffusion does not involve a semi permeable membrane.
A semi permeable membrane is a membrane that is selectively permeable to materials. It allows some materials to pass and does not allow other materials to pass. We can see the semi permeable membrane as the structure in the osmosis diagram that separates the two regions.
Diffusion does not require the use of a semi permeable membrane.

A student is performing an investigation using rennin and milk. Rennin is an enzyme that can solidify milk. She
puts milk in three test tubes with rennin and places the tests tubes in water baths at different temperatures
of 32°F, 98°F, and 212°F. She notices the rennin enzymes become denatured at 212°F and do not solidify
the milk. Which statement correctly describes the effect of the denatured enzymes?
A. Denatured enzymes are slowly active.
B. Denatured enzymes are no longer active
C. Denatured enzymes reverse the reaction.
D. Denatured enzymes speed up the reaction.
Answer:
The correct answer is - option B. denatured enzymes are no longer active.
Explanation:
Denaturation of the enzymes or proteins results in changes in their original structure which ultimately results in the loss of their particular functions. The denaturation of proteins or enzymes takes place due to extreme temperature or pH which leads to a change in the active site of an enzyme.
Due to this change, the substrate will no longer fit in the active site and become inactive as enzymes work together with the substrate and the active site is the essential part of the enzyme for its activity. In this case, this is condition takes place which makes it denatured at 212 degrees F.

Answer:
1. CELL
2. REPRODUCTION
3. IRRITABILITY
Explanation:
1. All living organisms are composed of CELLS, which according to the cell theory as proposed in the 1800's is the smallest structural and functional unit of life.
2. REPRODUCTION is a characteristics possessed by all living things. It is the process whereby living organisms/things create new living things.
3. IRRITABILITY is another characteristics of living things, which is the process whereby living things respond to changes in their environment called STIMULUS e.g heat, nutrient stress e.t.c.

In a study of a muscle disorder, several families exhibited vision problems, muscle weakness, and deafness. Analysis of the mtDNA (mitochondrial DNA) from affected persons in these families was analyzed using PCR (polymerase chain reaction) and gel electrophoresis. The unaffected samples were collected from multiple mitochondria, whereas each affected sample was collected from a single mitochondrion. What can you conclude about the affected individuals' mitochondrial DNA?
A. There is no common deletion.
B. There is one common deletion.
C. There are two common deletions.
D. There are more than two common deletions.
Answer:
A. There is no common deletion.
Explanation:
The correct answer to the given question is the option A. There is no common deletion.
In the study of the muscle disorder, the samples taken and the effects observed concludes that there was no common deletion among the analysed families and their mitochondrial DNA.
genetics and the environment both play roles in cell differentiation. which is the best example of an environmental factor influencing cell differentiation
Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
Through the process of natural selection, favorable forms of genes are passed on more than other forms of genes.
A. True
B. False

If the DNA integrates properly into the germ cells, the adult fly will contain _________________ that contain _____________________________. After mating, these flies can then produce progeny that will contain ______________________.
Answer:
Five pairs of autosomal and one pair of heterochromatic sex chromosomes.
Explanation:
The adult fly will contain 12 number of chromosomes that contain five pairs of autosomal and one pair of heterochromatic sex chromosomes. After mating, these flies can then produce progeny that will contain diploid i. e. double number of chromosome. One set of half chromosomes from the male fly while the other half chromosomes comes from female fly so the offspring will receive double number of chromosomes.

Margo notices that waves start passing her more often. What can she conclude about the frequency and wavelength of the waves?
Maro concluded that the frequency is increased while the wavelength would be decreased with respect to the wave that starts passing her more often.
What is Wavelength?Wavelength may be characterized as the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
The frequency or the energy of the wave is inversely related to the wavelength of any wave. This is because when frequency increases, wavelength (λ) decreases, and vice-versa. While the energy of the wave and frequency is directly related to one another.
Therefore, Maro concluded that the frequency is increased while the wavelength would be decreased with respect to the wave that starts passing her more often.

Why would looking for the persons responsible for sneaking endangered species (rare birds, for example) into the United States be considered a job for a forensic scientist
Answer:
Forensic scientists are able to find the answer.
Explanation:
The persons responsible for sneaking endangered species into the United States be considered a job for a forensic scientist because forensic scientist is able to find out the persons. Forensic scientist are the investigators who collect evidences from the crime scene and leads to the person who commit crime. So the forensic scientist is the only person who find out the persons responsible for sneaking endangered species.
