The rat snake is found in many different environments. They are found in woods, along the coast, in cities, and in mountains. They eat rats, birds, mice, and squirrels. Rat snakes also have varied appearances. They are gray, yellow, black, and mixes of these colors, depending on where they live. Which of the following explains the differences in colors of the rat snake?
A. The rat snakes' colors vary because they eat different foods in different environments that make their skin color change.
B. The rat snakes' colors vary as a result of artificial selection, which allows them to choose the best color suited for their environment.
C. The rat snakes' colors are adaptations caused by natural selection, which help them blend into their environment and hunt for food.
D. The rat snakes' colors vary because they have the ability to change their color like a chameleon in response to a changing environment
Answer:
c
Explanation:
Answer:
the answer is c
Explanation: because artificial selection would be like breading pure bred dogs, but in the wild it would be natural selection.
The genetic code for one amino acid molecule consists of A) five sugar molecules B) two phosphates C) three nucleotides D) four hydrogen bonds
Answer:
c
Explanation:
The genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.
What is genetic code?
Genetic code is defined as a sequence of instructions that directs the translation of DNA into 20 amino acids, which are the basic building blocks of proteins in living cells.
It can also be defined as the collection of instructions that live cells follow to convert information stored in genetic material into proteins.
Nucleotides are defined as a three-subunit chemical molecule consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group.
It can also be defined as the fundamental building component of nucleic acids.
There are basically two types of nucleotides.
Purines - They are defined as a heterocyclic aromatic organic molecule composed of two fused rings. Adenine, guanine and hydro xanthine are purines.Pyrimidine - They are defined as a simple aromatic compounds with a six-membered ring of carbon and nitrogen atoms. Cytosine, thymine and uracil are pyrimidines.Thus, the genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.

Because cilia cannot function properly, smokers have a frequent headache.
True
Answer:
Explanation:
The cilia sweep out mucus and dirt so your lungs stay clear. Smoking temporarily paralyzes and even kills cilia. This makes you more at risk for infection. Smokers get more colds and respiratory infections than non-smokers.
Because cilia cannot function properly, smokers having a frequent headache is a true statement.
What is Cilia?These are tiny hair projections which are found in the airway of the body and helps to prevent dust or foreign matter from getting to the lungs.
Smoking destroys it and leads to insufficient oxygen inhaled by the body as a result of presence of contaminants which may therefore lead to headache.

Transcription occurs in the _______, while translation occurs in the _______.
Answer:
Explanation:
In a eukaryotic cell, almost all transcription occurs in the nucleus and translation occurs mainly at ribosomes in the cytoplasm. In addition, before the primary transcript can leave the nucleus it is modified in various ways during RNA processing before the finished mRNA is exported to the cytoplasm.

What contribution to energy do carbohydrates make?
Answer:
Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

re
A. P2
B. F1
C. F2
Answer:
B. F1
Explanation:
Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.

Which product of photosynthesis is the most vital to other organisms?
if 10% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides contain each of the other three bases
Cytosine-
Adenine-
Thymine-
Answer:
Cytosine: 10%
Adenine: 40%
Thymine: 40%
Explanation:
So we know that Cytosine and Guanine are complementary and Adenine and Thymine are complementary.
Cytosine would be 10%
What's left is 80%, which would be divided by two because adenine and thymine have the same percents.
Adenine: 40%
Thymine: 40%

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

what is theory of to observe the neucles in cheek cells
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
