Answer:
10 starch
Explanation:
Starch is a polycharraide and is made up of glucose. Glucose is a monocharraide and is the simplest sugar. So if we take 10 glucose molecules and 10 starch molecules the starch has more energy since it's more complex than glucose.

Which characteristic listed below is most unique to plants?
Select one:
a.
Plants are heterotrophs.
b.
Plants undergo photosynthesis.
c.
Plants are multi-cellular.
d.
Plants are composed of eukaryotic cells.
Answer:
Plants are composed of eukaryotic cells.
Explanation:
Eukaryotic cells (as opposed to prokaryotic cells) have internal, membrane-bound organelles and a distinct nucleus that physically separates the genetic material of the cell from the all of the other parts of the cell. All protists, fungi, plants, and animals are composed of eukaryotic cells.
The characteristic that is most unique to plants is that they undergo the process of photosynthesis. Thus, the correct option for this question is B.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]Plants are eukaryotic in nature and have a double membrane cell organelle that is known as Chloroplast. These cell organelles have a green-colored pigment known as chlorophyll that captures the sunlight and converts it into chemical form and accomplishes the process of photosynthesis.
Therefore, the characteristic that is most unique to plants is that they undergo the process of photosynthesis. Thus, the correct option for this question is B.

Which statement about identical twins and fraternal twins is correct in regards to DNA?
A. Identical twins have different DNA, and fraternal twins have different DNA.
B. Fraternal twins share the exact same DNA, but identical twins do not.
C. Identical twins and fraternal twins share the exact same DNA.
D. Identical twins share the exact same DNA, but fraternal twins do not.
Answer:
D. Identical twins share the exact same DNA, but fraternal twins do not.
Explanation:
Identical twins are the twins formed from one egg provided by their mother and one sperm provided by their father. In contrast, fraternal twins are formed from two different sperms and two different eggs from the same father and mother.
Due to the fact that identical twins are as a result of one fertilized egg dividing into two, they share the same exact DNA. On the other hand, fraternal twins do not share the same exact DNA because they are formed from separate eggs and separate sperms.

Between 1984 and 2003, scientists mapped the human genome, which means they determined the pattern of billions of genes that make a human a human. Originally, it took years to map a single person’s total genome. By 2014 multiple genomes could be mapped in one day. What most likely allowed scientists to start mapping so much faster? a change to Mendel’s law of dominance more powerful computer technology the discovery of how germs work new scientists repeating gene experiments
Answers: a change to Mendel’s law of dominance
more powerful computer technology
the discovery of how germs work
new scientists repeating gene experiments
Answer:
More powerful computer technology
Explanation:
More powerful computer technology allowed the scientists to start mapping so much faster because powerful computer works very fast as compared to human brain. The activity or calculation which can be done by the human brain in hours, the computer done it in seconds due to its fast and quick response. So we can conclude from this discussion that powerful computer technology allowed the scientists to start mapping very fast.
A student used poster board to construct this model of DNA.Which statement describes this model of DNA?
Answer:
The model is inaccurate because the base pairs are incorrect.
Explanation:
The model of DNA that the student made was:
G-G
A-A
T-T
C-C
G-G
A-A
T-T
C-C
The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.
The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

What is the locomotory structure of yeast
Answer:
Yeast cell structure
Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.
Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.
Explanation:
Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.

when the body removes carbon dioxide bu the way of respiratory system what happens to the ph of blood
the more carbon dioxide in the blood the more acidic it will be. so when it is removed the acidity will decrease.
so the pH increases
When the body removes carbon dioxide, the PH of blood increases
The body control the blood's acid-base balance through different ways. The organs used for this control is lung, kidney and buffer systems.
The lung can control blood pH through the release of carbon dioxide. Carbon dioxide acidic and its accumulation in the body leads to an increase in PH.
When the blood PH is too low (i.e. acidic), the body increases breathing so as to expel(remove) more carbon dioxide thereby increasing the PH of the blood.

I think the answer is clouds.
Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Water vapor in the atmosphere is visible as clouds and fog.
answer:
Precipitation is most abundant where air rises, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.

.
Answer:
Stem cells have the ability to divide through mitosis and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of differentiation.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.
Stem cells have the ability to divide through mitosis and produce unspecified cells. They can be developed into a required tissue because of their ability of differentiation.
Stem cells are a special type of cell that may develop into a variety of specialized cells inside the body. They have the ability to differentiate into more specialized cells through the process of mitotic activity (mitosis) and perform restorative and regenerative roles.
Stem cells have significant and potential treatment for a variety of diseases due to their capacity to repair, regenerate, and grow into certain specialized cell types.
For example, bone marrow transplantation for people suffering with sickle cell disease.
