The role of adenosine triphosphate (ATP)
The energy required for cellular activities is provided directly by molecules of adenosine triphosphate (ATP). ATP is made of one adenosine molecule and three phosphate groups, called Pi for short. Each molecule of ATP stores a small quantity of chemical energy.

Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it burns. The excess heat released by the reaction is directly proportional to the amount of energy contained in the food.

Which of the following ideas is supported by Darwin's observation of local variation among tortoises in the Galapagos Islands A)

Hoochie [10]

Adaptation is supported by Darwin's observation of local variation among tortoises in the Galapagos Islands.

In biology, an adaptation, also called an adaptive trait, is a trait with a current functional role in the life of an organism that is maintained and evolved by means of natural selection. Adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation.

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

lara31 [8.8K]

Answer:

The answer is below

Explanation:

There are different types of biological tools, with each of them having different functions. However, for the sake of the question, some of the popular tools will be listed here.

1. Stockroom tools: this includes:

Beaker: this is essential to take or storing small substances

Bunsen Burner: this is important in the biological lab to heat a substance

Flask: this is essential in holding liquid substance.

Pipette: it forms of a lab spoon that is used in mixing substances to form a compound or mixture

2. Computer and Imaging system: this is important in image analysis and sequence-analysis programs

3. Cell cultures: this is used in the biological lab to enhance the complex cell differentiation required in the experimentation of animal cell structure

4. Microscopes: this is essential in determining and examining the microscopic organism that we can not see with our makes eyes

If a mutation occurs in a body cell and the mutation changes the phenotype of the individual, what will happen to the offspring

denis-greek [22]

Answer:

The correct option is B. The offspring will inherit neither the genotype nor the phenotype change.

Explanation:

Any changes which occur in the DNA sequence of a person are termed as mutations.

Mutations will only be transferred to offsprings if the mutated gene or sequence gets incorporated into the genome of the mutated person.

In the above scenario, the mutation is just changing the person's phenotype and it has not been incorporated in the genotype of the affected person. Hence, the offsprings will not inherit the mutation, nether in their genotype nor the phenotype.

When does facilitated diffusion occur?

Trava [24]

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.
