Answer:

A, B and C may be true

Explanation:

The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.

Researchers conducted a study concerning cellular transport in animal cells affected by mitochondrial

Shtirlitz [24]

Answer: Cellular transport independent of ATP like osmosis and difussion (Simple and facilitated).

Explanation: The animal affected has a mitochondrial disease that affects its capacity of ATP production, thus, the animal active transport will be afected since require ATP. On the contrary, the animal passive transport will be functional because its independent of ATP, like osmosis which is water transport in favor of concentration gradient and facilitated diffussion of small molecules.

Please help! I will give brainiest answer!

Over [174]

Answer:

Explanation:

The vehicles have the same amount of kinetic energy because they are travelling at the same speed. There is a great difference in their masses but their speed is same. Kinetic energy of a body depends on both mass and velocity. If the mass of an object increases, its kinetic energy also increases and vice versa while on the other hand, if we doubles the speed of an object its kinetic energy increases four times so we can conclude that objects having same speed leads to same kinetic energy.

Choose an activity that you, your family, or a friend engages in and which results in pollution. Discuss some of the ethical, ec

VMariaS [17]

An activity that me, my family or friends engage in that causes pollution is the use of vehicles that run on fossil fuels for transportation.

<u>Explanation:</u>

Fossil fuels contribute to pollution in a large way. Burning of fossil fuels release gases like carbon dioxide, carbon monoxide, oxides of sulphur, nitrogen etc which accelerate pollution. Petrol and diesel are the common fossil fuels used in vehicles.

Easy transportation is the necessity that makes people chose this alternative. There are other alternatives to fossil fuels. Vehicles can use cleaner fuels like CNG and LPG.

The vehicles can also be powered by electricity. But switching to these alternatives has some limitations as well which makes people find it difficult some times. It would never be a simple matter to sop this activity considering how important fast transportation is in this era.
