What supports, protects and maintains the shape of the cell? *Very rigid. *
A .golgi apparatus
B. cytoplasm
C. endoplasmic reticulum
D. cell wall
Answer: D. the Cell wall
Explanation: The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
Also it is also a ridged layer found outside of the cell membrane

Explanation:
The small intestine exchanges nutrients to help maintain homeostasis. Through the process of digestion, food is broken down into smaller pieces. Sugar is a molecule that supplies our cells with energy. Sugar is a large molecule and is transported through carrier proteins. Sugar molecules are often transported into the bloodstream even when the concentration of glucose is higher in the bloodstream than in the intestine. Based on this scenario, is the transport of glucose accomplished through osmosis, diffusion, or active transport?
Answer:
Diffusion
Explanation:
The sugar is spreading to various places within the body and is trying to make one place less concentrated.
Based on the given scenario,the transport of glucose is accomplished through diffusion.
What is diffusion?
Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)
a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.
b) The two sides of a cell membrane face different environments and carry out different functions.
c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.
d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.
Answer:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.
Explanation:
PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .
PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.
On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.
LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.
The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.
Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.
CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.
Hence , the correct option is B.

Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
A. If seed shape did not have a clearly recessive form.

How does the Gulf Stream affect weather in the United States? A. It brings cooler temperatures from the poles. B. It brings cooler temperatures from the tropics. C. The warm surface currents help create storms and fog. D. The cool surface currents produce cooler weather and fog.
Answer: C. The warm surface currents help create storms and fog.
Explanation:
The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.

The primary source of energy for most organisms are
Answer: The Sun
3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?
Answer:
Find the explanation below.
Explanation:
When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.
Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.
Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.
Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

millimeters
centimeters
decimeters

Answer: A
Explanation:
I took the test
Millimeters allow for the most accurate measurement.
Is cm extra accurate than mm?
A paper clip may be measured with both units (millimeter or centimeter) but a millimeter is the greater appropriate size to get an accurate measurement.
Why are millimeters more specific?A ruler marked in millimeters is extra unique than a ruler marked best in centimeters, considering a millimeter is a smaller unit than a centimeter.

What is electronegativity?The term "electronegativity" describes how attracted an atom is to the bonding electrons in molecules as opposed to other atoms.
American chemist Linus Pauling developed a set of dimensionless variables known as electronegativity values that vary from a little under one for alkali metals to a maximum of four for fluorine.
Electropositive elements are those that are on the left of the periodic table and have low electronegativities. We shall use the key attribute of the order of electronegativities F > O > N > C to explain the chemical properties of organic molecules.
Therefore, Zinc 1.65, Chromium 1.66, Tungsten 2.36 and Iodine 2.66.
