Which of the following are sites where waste products are released from the body but not where they are produced
O skin and anus
O large intestine and small intestine
O liver and kidney
O tubules and ureters
Answer:
Its A skin and anus
(just did test)
Explanation:
The skin and the Anus are sites where waste products are released from the body but not where they are produced.
Which process of the human body eliminates the waste products?Excretion is the biological process through which any unwanted or waste products are eliminated from the body.
Large and small intestines produce waste products that are not completely digested by the stomach. The liver and kidney are also the sites of waste products like the removal of carbon dioxide and synthesis of urine respectively.
Therefore, the skin and the Anus are sites where waste products are released from the body but not where they are produced.

What is the difference between a specialized plant cell and a specialized animal cell?
Answer:
Explanation:
Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Chloroplasts enable plants to perform photosynthesis to make food. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles if any are present.

In around 50 years, the peppered moth population changed from nearly all light wings to nearly all dark wings. Explain exactly how the moth population changed (evolved).
Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. ... Later, when pollution was reduced, the light-coloured form again predominated.

dose DNA have cells
i need to know for a assingment
Answer and Explanation:
Cells are made of DNA (Deoxyribonucleic Acid).
They provide the genetic instructions for making and forming a cell.
The DNA is found inside the nucleus of the cell.
Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome
DNA do NOT have cells, but cells DO have DNA.

Your best friend is concerned about a mole on her arm. Knowing that you are taking a biology class she comes to you and asks for your opinion. You take a sample of her mole and view it under a microscope. While counting a selection of 300 cells, you notice that 87 cells are actively undergoing mitosis. Should your friend be concerned?
Answer:
She should consult a dermatologist immediately.
Explanation:
When doing preemptive diagnosis of a mole, one should compute the Mitotic Rate (MR) - and the MR reported in the question is way above the highest category "greater than 4 per square millimeter" (to compare. there's around 2000 cells per sqmm of skin, so we're at over 500 per square millimeter).

Explanation:
Explain the consequences of altering a DNA base in the genome of an organism.
Answer:
Can be negative, neutral or positive change.
Explanation:
A negative change can result in diseases such as sickle cell anemia. This is because the amino acid that codon will code for changes.
A neutral change can result if the codon codes for the same amino acid as the original one.
A positive change can result if the new codon can express a beneficial phenotipic change. Something like having the body surviving on decreased amount of water or increased amounts of sodium is beneficial for organisms living near the equator.

Explanation:
A population of lizards carry a gene for scale color in which the dominant allele produces green scales while the recessive allele codes for brown scales. In the first generation, you determine that 75% of the population is green and 25% of the population is brown. In the second generation, you determine that 50% of the population is green and 50% of the population is brown. Finally, in the third generation, you determine that 25% of the population is green and 75% of the population is brown. Which of the following correctly explains this change in the genotype frequencies?(1 point)
The lizards mate randomly with each other.
The brown color is an adaptation that is being selected by the environment.
The lizards remain isolated from other lizards, only mating with lizards in their own population.
The DNA of these lizards carries no mutations from one generation to the next.
Answer:
1) There are no mutations in the DNA of the population.
2) The brown color is an adaptation that is being selected by the environment.
3) The number of individuals displaying each phenotype in both the current generation and the offspring.
4)The recessive phenotype in this population may serve as an adaptation in this environment.
5) A population of flies that maintains a population size of at least 1 million individuals.
Explanation:
just took the test (connexus student)
Correct answers are :
No mutations in the DNA.The brown color is an adaptation.individuals displaying current generation, offspring.Rcessive phenotype adaptation.Flies population has a size of at least 1 mn.What is a genotype?A genotype is a set of genetic material that characterize an organism and is also used or refer to the allies or the variant of that individual that carries genetic material.
The population of lizards has a gene for scale color that is a domain allele. The brown color is due to the adaptation of the species.
