You can increase the frictional force between 2 objects by : rubbing the two together or increasing the coefficient of friction (using rougher materials).

Answer:

Mitochondria:

An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. Also known as the 'powerhouse of the cell.'

Cell wall:

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Nucleus:

The positively charged central core of an atom, consisting of protons and neutrons and containing nearly all of the cell's mass.

Golgi bodies:

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

ER (Endoplasmic Reticulum):

A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough.

Cell Membrane:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Ribosomes:

A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.

Cytoplasm:

The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.

What would happen to a cell if the mitochondria stopped working?

grigory [225]

The cell would die because their would be no cellular respiration occurring which means the cell is not gaining energy and can’t use that energy.

Which lipid has the greatest influence on blood cholesterol levels?

SSSSS [86.1K]

Answer;

-Saturated fats

Explanation;

-Cholesterol is transported in the blood by different carriers. The relative amounts of cholesterol transported by each carrier can affect one’s risk for heart disease. The two major blood cholesterol carriers are LDL (low density lipoprotein) and HDL (high density lipoprotein).

-LDL cholesterol is known as “bad” blood cholesterol, and functions to deliver cholesterol to cells throughout the body and can be deposited as “plaque” on artery walls.

-Dietary fat, especially saturated and trans fats, may raise blood levels of total and LDL cholesterol. High total blood cholesterol levels and LDL cholesterol levels increase risk of heart disease.

Which of the following is a property of the stem of a dicot plant?Select one of the options below as your answer:A. ground tissu

Elodia [21]

I think the correct answer from the choices listed above is option A. A property of the stem of a dicot plant is that the ground tissue is differentiated into pith and cortex. Vascular bundles are not arranged sporadically instead arranged in a ring. Also, cambium does exist between xylem and phloem.
