Answer:
false, a cell CANNOt survive
A student wants to know the effect a mutation might have on a species survival. The change causes a rabbit to have mottled brown fur. The student runs a computer simulation for ten generations.What possible conclusions can you draw
Answer: A. Evolution occurred because the allele frequency changed over time.
C. The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E. The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur
Explanation:
Based on the information given, the possible conclusion that can be drawn from the options given are:
A. Evolution occurred because the allele frequency changed over time.
C. The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E. The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

Describe the interaction between the digestive and circulatory system of the earthworm
The earthworm has a closed circulatory system which runs through the
length of their bodies. The earthworm possesses blood vessels which aids
circulation of blood and nutrients to other parts of the body.
There are vessels in the intestine of earthworms which aid absorption and
transportation of digested food and nutrients to parts of its body.
The closed circulatory system in which blood vessels are present in all the
parts of the body also aids the transport of blood and other vital nutrients
to other parts of the body for survival.

What are two characteristics of DNA?
O Double bonded with hydrogen
O Organic and saturated
O Helix and double stranded
Phosphate and nitrogenous
Explanation:
DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.

What is an endocrine function?
Answer:
Explanation:
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

how do some chemicals increase the risk of cancer
Hey buddy i am there to help!
Exposure to some chemicals and hazardous substances can increase the risk of cancer. A few well-known carcinogens are asbestos, nickel, cadmium, radon, vinyl chloride, benzidene, and benzene. These carcinogens may act alone or with another carcinogen to increase your risk.
plz mark my answer brainliest
Answer:
Chemicals that cause cancer are direct acting carcinogens such as asbestos, nickel, cadmium, radon, vinyl chloride, benzidene, and benzene. Exposure can increase the risk of cancer by changing cellular metablolism or damaging DNA in cells, leading to the formation of tumors. Cells respond to chemicals in 3 ways, either the cell dies, it repairs itself, or it becomes cancerous.

Why is meiosis important for organisms?
Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

You have isolated two known bacteria with slightly different DNA patterns and have placed them in an environment with some unknown elements. After some time, you observe that cell No. 1 now has a different DNA pattern. Your goal is now to find out whether this new DNA was obtained by the cell from transformation or conjugation (and you know that it can only be from one of these two methods). Which of the following would be valid to investigate?
Test cell No. 1 for excised DNA that has been relocated
Test for foreign, similar DNA in the environment
Test for the presence of bacteriophages in the environment
Test for the presence of DNA patterns from cell No. 2 in cell No. 1
1 and 3
1 and 4

What makes up the inside or middle of the DNA ladder?
A. Sugar
B. Nucleotides
C. Nitrogen bases
D. Phosphate
Answer:
C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

hey this is the graphs for the question
The lesson question for this lab is "what is the effect of the type of food available on the frequency os different types of bird breaks?" The lab procedure you just studied should help you address this question. Well it? Explain.
Answer:
The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time. The independent variable of the lab is the type of food that is available to the birds.

What word is used to describe plant cells placed in a hypotonic solution?
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

Which process produces four genetically different gamete cells?
A. Mitosis
B. Meiosis
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Answer:
B. Meiosis
Explanation:
Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
