Blood cells are red, squishy, rounded, and have an indentation in them in the middle. Plant cells are green and firm and have a more square, boxy shape. Plant cells are larger than blood cells.
Plant cell is different in size, colour and shape from blood cell.
Plant cell has cuboid shape whereas blood cell has biconcave discoid shape. The colour of blood cell is red if it has oxygen or brown if it is no oxygen whereas plant cell has green colour. Plant cells have cell walls, ribosomes, endoplasmic reticulum, DNA and lysosomes but blood cells have no ribosomes, no endoplasmic reticulum, no DNA molecule and no lysosomes. The size of blood cell is 6.2–8.2 µm whereas the size of plant cell has 10 to 100 micrometers so we can conclude that there are a lot of differences between plant and blood cells.https://brainly.com/question/21283369

what happens to the field of view when you decrease the magnification power?
Answer: Increases
Explanation:
Field of view and magnification power are inversely proportional to each other. Decreasing the magnification (zooms things out) which means we can see a lot more of the sample, which means the field of view increases.
consider the following at 8 p.m. a diabetic is found to have a blood pH of 7.33 is Brian tells his diaphragm to contract more frequently so that his breathing rate increases consider how is considering homeostasis is restored what effect would this have on his PH range is hicity and hydrogen ion concentration .
Answer:
Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.

Explanation:
Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.
In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.
The stomach makes a substance that gives the correct pH for enzyme action. Name this substance.
Answer:
The stomach produces hydrochloric acid.It kills many harmful microorganisms that might have been swallowed along with the food.The enzymes work best in acidic conditions-at low pH
Hydrochloric acid is an important component of the gastric juice in animal species such as humans. This maintains the pH in the stomach.
What is Hydrochloric acid?Hydrochloric acid is also known as muriatic acid, it is an aqueous solution of the compound hydrogen chloride. Hydrochloric acid is a colorless solution with a distinctive pungent smell. It is mainly classified as a strong acid. However, it is a component of the gastric acid in the digestive systems of most of the animal species, including humans. Hydrochloric acid is an important component of the digestive system.
Hydrochloric acid (HCl) is a part of the gastric juice. It plays an important role in creating the pH required for pepsin activity and for the maintenance of this pH. Parietal cells in the stomach are responsible for the production of HCl acid by secreting hydrogen and chloride ions separately. When pepsinogen and hydrochloric acid exist together in the gastric juice, pepsin is converted into its active form.

How many nucleotides equals 1 amino acid ?
Answer: Three nucleotides
Explanation: Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids.
A codon is a group of three nucleotides in DNA or RNA that is used to encode genetic information. Each codon represents a particular amino acid or a signal to cease the production of proteins. Thus, there are three nucleotides for every amino acid in the interaction between them.
Here is a more thorough justification:
The genetic code is made up of codons, which are groups of three nucleotides apiece. Four distinct nucleotides—adenine (A), cytosine (C), guanine (G), and thymine (T) in DNA, or uracil (U) in RNA—can be combined to create a total of 64 potential codons (43).
These codons act as informational units that specify the use of particular amino acids while synthesizing proteins.

Calcium nitrate is a compound commonly used as a plant fertilizer in agriculture and also in
wastewater treatment facilities. Let's suppose you need to prepare a 0.2 molar (0.2 M)
solution of calcium nitrate to spray a crop field. You will need to prepare 500 Liters to have
enough of this solution to spray the entire field. How much calcium nitrate will you need?
Answer:
16400g
Explanation:
The amount of Calcium nitrate {Ca(NO3)2} that will be needed can be calculated as follows:
Molarity (M) = number of moles (n) ÷ volume (L)
According to this question, molarity = 0.2M, volume = 500L
number of moles = molarity × volume
number of moles (n) = 0.2 × 500
n = 100moles
Using mole = mass/molar mass
Molar mass of Ca(NO3)2 = 40 + {14 + 16(3)}2
= 40 + (14 + 48)2
= 40 + 62(2)
= 40 + 124
= 164g/mol
Mass = mole × molar mass
mass = 100 × 164
mass = 16400g of Ca(NO3)2

B. Apple juice 80 proof liquor (contains water, 40% ethanol, flavors)
C. Mineral water (contains water, minerals)
Answer:
Bread Flavored syrup (contains water, high sugar concentration, flavors, e.g., used to flavor coffee and drinks)
Explanation:
Food spoilage refers to a situation in which food is no longer fit for consumption due to the action of certain microorganisms on the food. Hence, microorganisms cause the spoilage of food and beverages.
The rate of action of microorganisms on different beverages depends mostly on the content of the beverages.
Yeasts are often responsible for the spoilage of beverages with high sugar content and these tend to spoil faster than other beverages.
What would you expect to happen to a plant as temperature and precipatiom increases? Write your claim and evidence!!
Answer:
Both have great effect on plant when increases from a certain limit.
Explanation:
When the temperature falls in the optimum range it has a good effect on plants growth because the rate of photosynthesis is maximum. Precipitation also has a great effect because it provides water that is necessary for the plants. If the temperature increases from a certain limit, it burns plant body and decreases photosynthesis whereas if precipitation increases it causes flood condition which kills the plant due to removal from the soil.
