23. In both plant and animal cells, the cell
membrane
(1) produces enzymes
(2) controls reproduction
(3) is composed of sugars
(4) regulates diffusion
Answer:
the answer is option 1
The Cell membrane regulates diffusion, in plants and animal cells.
What is a Cell Membrane?Every biological cell has a thin membrane that separates it from the rest of the environment this membrane is known as a cell membrane.Cell membranes is made of lipids and proteins.The cell membrane's chemical nature makes it extremely flexible, making it a perfect border for quickly growing and dividing cells.Cell membrane is a semi-permeable membrane.Cell membrane does not produce enzymes.
Hence, the option (1) is incorrect.
Cell membrane cannot control reproduction.
Hence, option (2) is incorrect.
The main constituents of cell membrane is lipids and proteins, not sugars.
Hence, option (3) is incorrect.
Cell membrane regulates diffusion, because the cell membrane contains the semi-permeable membrane which allows only lipids and certain small molecules in the cell.
Hence, option (4) is correct.
Therefore, the Cell membrane regulates diffusion, in both plants and animal cells.

The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.

The normal sodium level in human blood is 135 mEqjL. If a blood test taken immediately after a meal reveals a sodium level of 150 mEqjL, what will most likely result
Answer:
Causes high blood pressure, heart disease, and stroke.
Explanation:
Increase occur in high blood pressure, heart disease and stroke due to increase in sodium level in the blood. If the meal has no sodium then there is no increase occur in the sodium level in human blood while on the other hand, if the meal has more sodium then there is high increase in sodium level in human blood which causes high blood pressure, heart disease, and stroke.

Examine equations A and B below. Then answer the questions.

20. Which equation represents the formation of water?
21. Which equation represents the formation of an acid solution?
22. How many atoms of oxygen (O) are on both sides of equation
23. How many atoms of hydrogen (H) are on both sides of equation
24. How many atoms of hydrogen (H) are on both sides of equation
25. In which equation are carbonic acid molecules broken apart into
hydrogen ions and bicarbonate ions?
Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B
Explanation: A has H2O (water). B has a hydrogen ion, so acidic.
In B H2CO3 is carbonic acid
The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.
What is a chemical reaction?Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:
2H₂ + O₂ → 2H₂O
Equation B represents the formation of the acid as hydrogen ions are released along the product. The proton donation (hydrogen ion) is the characteristic property of the acids.There are 2 oxygen atoms in equation A, and 3 atoms of oxygen in equation B.There are 4 hydrogen atoms in equation A and 2 atoms of hydrogen in equation B.In equation B, carbonic acid breaks to form hydrogen ions and bicarbonate ions as:H₂CO₃ → H⁺ + HCO₃
Here, carbonic acid dissociates a proton that makes the solution acidic.
Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

In organisms other than plants, when and where is the most ATP produced?
in cytoplasm, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration
Answer:
D. In mitochondria, during cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.
