What happens if p53 is mutated?
stira [4]

Answer:

Most TP53 mutations change single amino acids in the p53 protein, which leads to the production of an altered version of the protein that cannot control cell proliferation and is unable to trigger apoptosis in cells with mutated or damaged DNA. As a result, DNA damage can accumulate in cells

Do autotrophs need to perform cellular respiration?
nydimaria [60]
Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.

Four students were asked to classify the activities of the people in the picture below as examples of either potential or kineti
frez [133]

Hi there!

\large\boxed{\text{The first choice.}}

Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.

Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.

-----------------------------------------------------------------------------------------------------------

Looking at the examples in the table,  we can sort them as such:

Girl swimming laps- Kinetic energy because the girl is in motion.

Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.

Girl hitting volleyball - Kinetic energy because the volleyball is in motion.

Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.

Therefore, the correct table is table 1.
