Answer: The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system.
Explanation: Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.

Somatic stem cells are extracted from _____
A. An Egg
B. An Embryo
C. Developed Organs
D. A blastocyst
Answer:
A. an egg
Explanation:
The process of somatic cell nuclear transplant involves two different cells. The first being a female gamete, known as the ovum (egg/oocyte). In human SCNT (Somatic Cell Nuclear Transfer) experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation.
Polymer of carbohydrates
Answer:
Carbohydrates are one of the four basic macromolecules of life. They are a polymer made up of monomers called monosaccharides. These building blocks are simple sugars, e.g., glucose and fructose. ... Finally, polysaccharide is the name given to long chains of monosaccharides connected
Both starch and cellulose are polysaccharides made of individual glucose molecules. Why then can humans digest starch but not cellulose
Answer:
Starch and cellulose are two very similar polymers. In fact, they are both made from the same monomer, glucose, and have the same glucose-based repeat units. ... Your body contains enzymes that break starch down into glucose to fuel your body. But we humans don't have enzymes that can break down cellulose
This transportation process requires the cell to move particles from low concentration to high concentration. active transport facilitated diffusion osmosis diffusion
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Explanation:

Which of the following statements BEST describes ASEXUAL reproduction?
Question 8 options:
A single-celled organism uses meiosis to create two identical copies of itself.
Two multi-celled organisms uses meiosis and fertilization to create a unique offspring.
Two multi-celled organisms use mitosis and fertilization to create a unique offspring.
A single-celled organism uses mitosis to create two identical copies of itself.
The statement “ A single-celled organism uses mitosis to create two identical copies of itself” best describes asexual reproduction
The statement which best describes the mode of asexual reproduction is that a single-celled organism uses mitosis to create two identical copies of itself. Thus, the correct option for this question is D.
What is Asexual reproduction?Asexual reproduction may be characterized as a mode of reproduction in which a new offspring is produced by a single parent. This type of reproduction does not involve the fusion of gametes or a change in the number of chromosomes.
Asexual reproduction is homologous to the process of mitosis. This is because both of them involve the production of two identical daughter cells from a parental cell.
While meiosis produces four daughter cells which are genetically unique to the parent cells. It is the characteristic feature of sexual reproduction that is opposite to an asexual one.
Therefore, the correct option for this question is D.

24
Explanation:
10x + y = 4(x + y) Remove the brackets
10x + y = 4x + 4y Subtract 4x from both sides
10x - 4x + y = 4x - 4x + 4y Combine like terms
6x + y = 4y Subtract y from both sides
6x + y - y = 4y - y Combine
6x = 3y Divide by 3
6x/3 = 3y/3
2x = y
Put this result in the equation below
x*y = 8
x(2x) = 8
2x^2 = 8 Divide by 2
2x^2/2 = 8/2
x^2 = 4 Take the square root.
√x^2 = √4
x = ± 2
y = 2*x = ±4
Answer
The plus answer for x and y is the one we'll see about first.
10x + y = 20 + 4 = 24
24 =? 4(2 + 4)
24 =? 4*6 = 24
The product of it's digits = 2 * 4 = 8.
24 is definitely one answer.
========================
What about -2 and - 4
-24 = 4(-2 + -4)
-24 = 4*-6 = -24
That works as well
How do oceans contribute to creating winds?
A.Ocean currents create momentum that pull air with them.
B.Ocean water vapor pushes air causing it to flow in different directions.
C.Ocean energy is transferred to or from the air creating density differences.
D.Ocean water vapor eventually condenses into clouds and wind.
Answer:
Explanation:
Ocean energy is transferred to or from the air creating density differences.
Oceans contribute to creating winds as ocean energy is transferred to or from the air, creating density differences. The correct option is c.
What is ocean energy?The ocean waters are continually changing. Wind, water salinity, temperature, ocean floor topography, and the earth's rotation all influence ocean current flow patterns.
The majority of ocean currents are caused by wind and solar heating of surface waters near the equator, while some are caused by density and salinity fluctuations in the water column. In contrast to tidal currents along the shore, ocean currents are typically consistent and travel in one direction.
The transfer of energy from the ocean to the atmosphere causes the atmosphere to cool. The energy travels in a disturbance, which in an ocean is a wave, therefore the wave generates energy and transports it through the water.
Therefore, the correct option is C. Ocean energy is transferred to or from the air, creating density differences.
