Answer:

I think your answer is wrong. The right answer is D. Nucleus & Ribosome.

Explanation:

A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Why do traits that give an organism a disadvantage exist during meiosis? Please be as descriptive as possible and write it in yo
Roman55 [17]

Answer:

Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.

The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

Explanation:

Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.

Mama L [17]

Answer:

-The three main types of muscle include skeletal, smooth and cardiac.

- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. ...

Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. ...

Cardiac muscle – the muscle specific to the heart.

-Skeletal muscles are attached to the skeleton by tough connective tissues called tendons

-Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.

-They are lightweight yet strong and hard, and serve multiple functions.

-The joints help attach bones to one another to provide flexibility & allow the muscles to help give the bones a way to move.

- The nervous system helps all the parts of the body to communicate with each other.

-Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body.

-homeostasis?

Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.

ive listed the answers in order. hope this helps :) i will appercite if you give me brainliest.
