How many neutrons are in Cesium-130(130/55Cs)?

There are two main types of cell division—mitosis and meiosis. Which of the following is a true statement about the end products

Andrei [34K]

Mitosis happens in all types of cells. in this division, the cell will double it's number of chromosomes and then will be divided into two separated cells. so the number of chromosomes in product is equal to the number of chromosomes of the first cell

but meiosis only happens to produce gametes. the cell will be divided into two separated gametes.
in this division the number of chromosomes won't be doubled. so gametes have the half number of a normal person chromosomes.

good luck

Proteins may be classified according to their three-dimensional shapes. Determine whether the following examples and description

m_a_m_a [10]

Answer:

-often function as enzymes or transport proteins ⇒ globular proteins

-peptide chains arranged in long strands, or fibers ⇒ fibrous proteins

-peptide chains highly folded into spherical shapes ⇒ globular proteins

-keratins ⇒ fibrous proteins

-hemoglobin ⇒ globular proteins

-water-soluble ⇒ globular proteins

-collagens ⇒ fibrous proteins

-insoluble in water ⇒ fibrous proteins

-generally function in structure and support ⇒ fibrous proteins

Explanation:

Fibrous proteins are composed by large polypeptide chains which interact each other and form large structures. They have water insoluble and have structural and protection functions- they are components of cells and tissues. Examples are: collagen, fibronectin, keratin, elastin, actin.

Globular proteins have a spherical compact structure in which hydrophobic aminoacids are buried inside the structure and hydrophilic aminoacids (which can interact with water molecules) are exposed to the exterior medium. For this, they are water soluble. They have often transport and catalytic functions. For example: hemoglobin, mioglobin, albumin, enzymes in general.

“If cells reproduce by copying themselves, how do we get all of the different cell types in the body?

Dennis_Churaev [7]

Answer:

The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.

We are multicellular organisms, different types of cells are required to do different function.

Explanation:

Actually cells in our body won't reproduce, LOL.

It get divided ( see the attached image )

A carrier of a genetic disorder who does not show symptoms is most likely to be ________ to transmit it to offspring.

IgorLugansk [536]

A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to offspring. This particular individual has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease. They are referred to as genetic carriers. The chance of two carriers having an offspring with the disease or genetic disorder is 25%
