How are organisms able to generate ATP without oxygen?

Answers

Answer:

Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. ... This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

How are the functions of a cell similar to the functions of an organ system?

Answers

Answer:

Organelles in a cell are essentially the same as organs in an organism. The mitochondria is the powerhouse of the cell, as we all know. It creates ATP, which is what gives the cell energy. This is similar to how we consume food and create energy from it. Cell membranes are similar to skin, as they keep needed things in, and unwanted things out. Our cells need water too, as it helps create the cytoplasm. We need water to keep us alive and well, as it helps to create many of our needed bodily fluids, and rid us of toxins.

What are three methods for detecting radioactively labeled DNA in an experiment?

Answers

Answer:

Limitations. detect low abundance DNA binding proteins from lysates. test binding site mutations using many probe configurations with the same lysate. test binding affinity through DNA probe mutational analysis. non-radioactive EMSA possible using biotinylated or fluorescently labeled DNA probes.

Explanation:

Answer:

Proteins interact with DNA through electrostatic interactions (salt bridges), dipolar interactions (hydrogen bonding, H-bonds), entropic effects (hydrophobic interactions) and dispersion forces (base stacking). These forces contribute in varying degrees to proteins binding in a sequence-specific or non–sequence-specific manner.

Aerobic respiration involves the reaction of oxidation which involves the acceptance of electrons when the molecular oxygen reacts with protons to form water molecules. Thus, the correct option is A.

What is Aerobic respiration?

Aerobic respiration is the chemical process in which molecular oxygen is used to make the energy in the form of ATP from carbohydrates. It is also called as aerobic metabolism, and oxidative metabolism.

Aerobic organisms can use molecular oxygen (O₂) to generate energy in the form of adenine triphosphate (ATP). The role of molecular oxygen in the process of cellular respiration is to act as the end acceptor of electron. As the electrons are dropped off at the inner mitochondrial membrane during the process of cellular respiration, they travel through the electron transport chain and  are finally accepted by the molecular oxygen to form water.

Therefore, the correct option is A.

Which of these characteristics is NOT a property of water? (SC.912.L.18.12) A. Increases density as it solidifies B. Functions as a universal solvent C. Exhibits a highly cohesive behavior D. Moderates changes in temperature

Answers

Answer:

Option A.

Increases density as it solidifies

Explanation:

Increases density as it solidifies is not the characteristics of water because when water solidifies or freeze it become less dense or lighter compare to liquid water. When water solidifies to ice, it molecules are packed together and it is arranged in six sided crystalline shape which make it to be less dense or lighter than the liquid water molecules which is denser or more heavier.

Heat energy is transferred on Earth by the processes of convection, conduction, and radiation. How does heat energy cause materials to move during convection? Complete the sentences below.
It causes denser materials to ______.

It causes less dense materials to ______.
Answer choices are Rise, Sink, Reflect, Absorb.

Answers

Answer:

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.

In heat transfer by convection, heat energy causes denser materials to sink and causes less dense materials to rise.

What is heat transfer?

Heat transfer refers to the process by which heat energy is transferred from one point at higher temperature to another at lower temperature.

Heat energy is transferred on Earth by the processes of convection, conduction, and radiation.

Thus, during convection, heat energy causes denser materials to sink and causes less dense materials to rise.

2.Muscles continually push bones to be straight.
3.Muscles constantly contract to help fight gravity.
4.Muscles constantly contract to help work with gravity.

Answers

Answer:

a

Explanation:

Muscles continually align themselves vertically to help maintain posture.

What is Muscular system?

Muscle fibers are specialized cells that make up the muscular system. Their ability to contract is its main characteristic. Movement is caused by muscles that are connected to blood vessels, internal organs, or bones.

Muscle contraction is the primary cause of almost all bodily movement. Cilia, the flagellum on sperm cells, and certain white blood cell amoeboid movement are examples of exceptions to this rule.

Walking and running are two examples of visible movements that are produced by the coordinated action of joints, bones, and skeletal muscles. Skeletal muscles can also make softer motions that influence different facial expressions, eye movements, and breathing.

Therefore, Muscles continually align themselves vertically to help maintain posture.
