I'm giving Brainilest if you answer this and some points and 5 stars and a Thanks: Describe the positions of high and low pressure and the temperature of the land and water to explain how land breezes form.
Answer:
A high pressure system works downwards and brings with it good weather, while a low pressure system works upwards and brings bad weather. Due to the Earth’s rotation and friction on its surface, air currents are formed. When these currents move clockwise and out of the center, a space is formed at the center. The land quickly loses its heat whiles the water retains its warmth. That means the air over the water is warmer, less dense, and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.

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.

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.

A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine. Based on this information, which of the following correctly lists the amounts of the three remaining bases for this sample
A 20% cytosine, 20% thymine, 20% guanine
B 30% cytosine, 209. thymine, 30% guanine
C 10% cytosine, 30% thymine. 40% guanine
D 30% cytosine, 30% thymine, 20% guanine
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.
According to the information given above, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.
What are Bases?Bases may be defined as the monomer of nucleic acids such as DNA or RNA. These nucleotide bases are composed of a pentose sugar, and a phosphate group.
There are four types of nucleotide bases that are generally found in any nucleic acid sequence. They are adenine, guanine, thymine, and cytosine. But in RNA, Thymine is replaced by Uracil.
According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
∴ A = T : G = C.
If the amount of adenine is 20%, the amount of thymine is also 20%. Together, they constitute 40% of DNA, now the remaining is 60%.
This 60% is then equally divided into two parts between 30% cytosine and 30% guanine.
Therefore, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.

.
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.

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.
