What three functions does the cell membrane have?
Answer:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell.

Which type of carbohydrate would provide an immediate source of energy
Answer:
glucose carbohydrates
Explanation:
As an immediate source of energy, glucose is broken down during the process of cellular respiration, which produces ATP, the energy currency of the cell. Glucose or blood sugar, is the main source of energy for your body's cells, tissues, and organs.

when the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration
When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.
CONCENTRATION GRADIENT:
Concentration gradient is a term used to refer to a difference in solute concentration on opposite sides of the membrane of an organism. If the concentration on the external part of a cell is higher than that of the internal part of the cell, a concentration gradient is said to have occured. Concentration gradient is the basis of osmotic movement of water into and out of a cell. Therefore, When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.Learn more at: https://brainly.com/question/8195294?referrer=searchResults

Why are different types of cancers named based on where in the body they originate (breast cancer, skin cancer, bone cancer, etc.)? Why does it matter from which organ or tissue type the cancer developed?
Answer:
Cancer is caused by abnormal cell division. However, a skin cell is different from a bone cell. Because of that, the cancers that can occur behave differently.

(WILL MARK BRAINLIEST) A college administrator wants to know whether an orientation workshop will increase success rates for first-time college students. Which of these should he manipulate?
a) the number of first-time college students that are admitted
b) whether students receive an orientation workshop or not
c) the assessments that are used to determine success rate
d) when students are required to take placement exams
e) all of the above
Answer:
E) All of the above
Explanation:
The reason I say that is because he is trying to increase the success rates of first-time college students. If you admit a certain amount of first-time students the rates will go up. B if he does that he will be determining which ones get admitted and tested.
Einsteins Theory of Relativity can be
supported with evidence of light doing
what around the sun?
bending.
Answer:
Einsteins Theory of Relativity can be
supported with evidence of light doing
what around the sun?
In 1919 observation of a solar eclipse confirmed Einstein's prediction that light is bent in the presence of mass. This experimental support for his general theory of relativity garnered him instant worldwide acclaim. ... This has been measured directly and also through the gravitational redshift of light.
Answer:
The Earth moves around the Sun, due to the Sun's gravity. ... According to Newton's theory, the Earth should know immediately that the Sun had disappeared. But Einstein said that couldn't be right. Because, according to him, nothing can travel faster than the speed of light — not even the effects of gravity.
Explanation:
•Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same•for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.
•Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends

How do human cells resulting from meiotic division differ from human cells resulting from mitotic division?
The human cells resulting from meiotic division differ significantly from the cells resulting from mitotic division because :
Mitosis produces two diploid (2n)somatic cells that are genetically identical to each other and the original parent call,
whereas the meiosis produces four haploid (n) gametes which are genetically different from each other and the original parent cell as they are germ line cells.
Difference between mitosis and meiosis :Mitosis is a fundamental process for life as our cell divides by this method in the development and growth of the body.The cell duplicates all of its contents, including chromosomes and splits to form two identical daughter cells. This takes place in somatic cells.Meiosis ensures humans have the same number of chromosomes as this takes place in germ cells like egg and sperm cell and produces half the number of chromosomes(n) and during fertilization they unite and become double that is 46 chromosomes.

Describe the relationship between the wavelength and frequency of electromagnetic waves
Answer:
Frequency is inversely proportional to wavelength.
Explanation:
frequency is the number of oscillations in a unit of time.
Wavelength is the length between one oscillation and the next oscillation.
take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)
Now get two pins and pin them at a certain distance apart.
take the first spring and attach its two terminals to the pins.
Repeat the above procedure, but double (increase the distance x2) the distance between two pins.
Now you have to measure how many coils are there within 5cm of the two springs.
you'll observe that the second spring has half the coils of the first spring within 5cm.
In here no. of coils is the frequency
5cm length is time.
distance between coil is the wavelength.

Match the following terms pertaining to Earth's early formation with the correct description.
The process on the accumulation of ice and rock to form the early earth is called as accretion.
What is accumulation?Accumulation is defined as the ongoing accumulation of foreign compounds inside an organism, such as harmful chemicals or insecticides. Accumulation in the context of trading refers to the size of a position within an asset that increases as a result of multiple transactions. Accumulation also denotes the incorporation of positions across the board in a portfolio. It can also be used to describe a rise in buying activity inside an asset.
Differentiation is defined as the procedures that turn immature cells into mature ones with particular activities. Iron catastrophe is defined as a huge geological event that is thought to have occurred early in Earth's history and during which heavy metals like iron and nickel gathered in the core for a geologically brief time. Earth's layer include Crust, mantle, core, lithosphere, asthenosphere, mesosphere, outer core, inner core.
Thus, the correct match of the following is 1, 2, 3 and 4 is C, B, D and A.
