Biochemical analysis uses similarities in __________ as evidence for evolutionary relationships.A)DNA sequences
B)bone structure
C)cellular architecture
D)homologous structures

Answers

The correct answer is (a.) DNA sequences. The biochemical analysis uses similarities in DNA sequences as evidence for evolutionary relationships. The biochemical analysis is the key component of drug discovery and research, with the use of DNA sequences; a process of determining the organized structure of nucleotides within a DNA molecule.

Explanation:

Which of the following is NOT true about energy balance? A. Energy balance is influenced by the amount of exercise one gets and their dietary habits. B. Inactive people use more energy so they should consume fewer calories. C. Stored body fat will increase if calorie intake is greater than energy used. D. Energy balance is the balance between the amount of calories consumed and the amount used for energy.

Answers

The option C, which is, Inactive people use more energy so they should consume fewer calories is not true about energy balance.

Energy balance refers to the relationship between the energy in and energy out. Energy balance is affected by the amount of exercise one gets and their dietary habits. Stored body fat will increase if calorie intake is greater than the energy used.

Stored body fat will increase if calorie intake is greater than the energy used. Energy balance is the balance between the number of calories consumed and the amount of energy used.

The difference between the number of calories consumed and burned each day is energy balance. An inactive person uses less energy as compared to an active person due to less work out and therefore would require fewer calories.

Further Explanation:

The difference between input and output energy or calories is the energy balance of the body. The energy balance can be categorized as;

a) Perfect balance: In the energy equation if the input and output difference in energy comes out to be zero, then one has a perfect energy balance. This means neither weight is lost nor gained. During the weight loss journey, the people in their weight maintenance stage show perfect energy balance.

b) Positive energy balance: If the difference in the energy input and output results in a positive number, a person gains weight. The people like growing children, weightlifters, and pregnant women show positive energy balance and bulk up.

c) Negative energy balance: If the difference ends up in a negative number, a person achieves an imbalance required for weight loss. This is called energy deficit and the person slims down due to the negative energy difference and loss of calories.

An active person uses more of its consumed energy to perform physical activities and hence would consume more calories to keep the body at its pace. Whereas, an inactive person do little or no physical activities and therefore requires less energy. As a result, he/she would consume fewer calories due to low energy requirements.

Isotopes of uranium are the most common fuel used in nuclear power plants. True/ False

Answers

This is true, they are a large unstable isotope that can be broken down into smaller more stable elements to release energy to power turbines and generate electricity

Answer:

True

Explanation:

Isotopes of uranium, specifically uranium-235 and uranium-238, are commonly used as nuclear fuel in power plants. When these isotopes undergo nuclear reactions, they release large amounts of energy, which can be used to generate electricity.

The isotope of an atom containing 31 protons and 39 neutrons suddenly has two neutrons added to it. What isotope is created?

Answers

The answer is gallium-72. The isotope of an atom containing 31 protons and 39 neutrons suddenly has 2 neutrons added to it. So, it has 31 protons and 41 neutrons (39 + 2 = 41). The mass number of an element is the sum of the number of its protons and neutrons: 31 + 41 = 72. The atomic number of an element is the number of its protons. This isotope has 31 protons and its atomic mass is 31. According to the Periodic table, gallium has atomic mass of 31. Thus the isotope is gallium-72.

Answer:

Gallium-72
