Answer:
A substance in a solution that releases and captures hydrogen ions, keeping the pH the same
Explanation:
A substance that may release a proton or hydrogen ion (H +) is referred to as an acid.
What is acid?Hydrogen ions and chloride ions are created when hydrogen chloride, which is suspended in water, ionizes. A particle or ion that may produce a hydron (proton or hydrogen ion H+ is known as an acid.
Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid. A base is a molecule or ion that can take up an acid's hydrogen ion.
Typically, sour tastes help to identify acidic chemicals. capable of forming a covalent connection with an electron pair on (a Lewis acid). Proton donors, also known as Brnsted acids, make up the first level of acids.
Therefore, that may release a proton or hydrogen ion (H +) is referred to as an acid.

Animals like lions and wolves reproduce using sexual reproduction.
O True
False
Answer:
yes
there mammals so they need to have sexual reproduction compared to fish they dont need sexual reproductions to have a organism (baby)
Explanation:
Yes, the animals like wolves and lions reproduce by se-xual reproduction.
Se-xual reproduction in mammals:The process of production of offspring by combining genetic components from two individuals of different se-xes, that is, male and female is termed se-xual reproduction. In higher animals like mammals, that is, lions and wolves, the process of se-xual reproduction takes place.
The mammals generate gametes, that is, egg and sperm via the process of meiosis in gonads, that is, ovaries in females and testes in males. The production of eggs takes place by the process of oo-genesis, and the production of sperm takes place by sperma-togenesis.
Afterwards the fusion of male and female gametes takes place, that is, the process of fertilization occurs and generate a diploid zygote.
Thus, the given statement is true.

TRUE OR FALSE: A coiled structure of DNA and protein that forms in the cell nucleus during cell division is called a chromosome
Answer:
TRUE!!!
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
hope this helps! :D
A chromosome is a coiled DNA and protein structure that develops in the cell nucleus during cell division.
Thus, chromosomes are important for transporting and passing genetic information from one generation to the next. They house an organism's genetic material. When cells divide, they become visible under a microscope and take the form of compressed formations. Every species has a certain number of chromosomes.
Chromosomes are essential for cell division because they make sure that genetic material is accurately distributed to daughter cells. For effective cell function and heredity, they must have a compact and well-organized structure made of DNA securely coiled around histone proteins.

series of experiments in which 32P-labeled inorganic phosphate were introduced to erythrocytes (red blood cells) undergoing glycolysis. Would you expect to see the labeled phosphate in any glycolytic intermediates
Answer:
The labeled inorganic phosphate will be found in 1,3-bisphosphoglycerate
Explanation:
In the fifth reaction step of glycolysis, glyceraldehyde-3-phosphate is oxidized by the enzyme glyceraldehyde-3-phosphate dehydrogenase to 1,3-bisphosphoglycerate. Two molecules of NAD+ are reduced to form two NADH + 2H⁺. The energy released by the oxidation process is used to add an inorganic phosphate group to position 1 of two molecules of glyceraldehyde-3-phosphate to form two molecules of 1,3-biphosphoglycerate.
In the sixth step, the two molecules of 1,3-biphosphoglycerate are converted to 3-phosphoglycerate, with the high-energy phosphate group in position 1 added to ADP producing 2 ATP through substrate-level phosphorylation.
Since in the experiments,32-P-labelled inorganic phosphate were introduced to erythrocytes undergoing glycolysis, the inorganic phosphates would be expected to seen in the molecules of 1,3-biphosphoglycerate. However, since, the phosphate group is subsequently added to ADP to form ATP, it will no longer appear in other intermediates.

Which are examples of abiotic factors? Select three options.
sunlight
oxygen
rotting leaves
stones
fungi
Sunlight, oxygen, and stones are the examples of abiotic factors. Therefore, the correct option is A, B and D.
What are abiotic factors?Abiotic factors are the non-living components of an ecosystem that affect the organisms living within it. Examples of abiotic factors include sunlight, air, water, soil, temperature, and physical features such as rocks and mountains.
Option C, rotting leaves, is an example of a biotic factor, Option E, fungi, can be either biotic or abiotic, depending on the context. Fungi are living organisms and can be considered biotic factors when they are interacting with other organisms in an ecosystem.
However, they can also break down dead organic matter and contribute to the decomposition of organic material in the soil, which makes them an important part of the abiotic environment. Therefore, the correct option is A, B and D.

main stages of the cell cycle
Answer: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Which of the following statements is correct?
Your eyes look different than your liver, because the cells that make up these
organs have different genes.
o As cells and tissues differentiate, they lose the genes they do not need.
O All cells have the same genes, but different genes are active in different cells.
Cells do not have DNA.
Answer:
The statement that is correct is that all cells have the same genes, but different genes are active in different cells.
Explanation:
Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation.
The other choices are wrong because:
The eyes look different from the liver, because they have the same genes, but only some are expressed. Differentiated cells and tissues do not lose their genes. All cells have DNA.When looking under a microscope comparing the muscle cell of an Olympic athlete and an average adult you notice there is a significant difference. What is the difference? Why does this difference exist?
Answer:
More mitochondria in athlete's muscle cells.
Explanation:
There is a significant difference in the muscle cell of an Olympic athlete as compared to an average adult because Olympic athlete has more number of mitochondria present in their muscles cells as compared to muscle cell of an average adult. The main reason for this is that Athlete performs harder activities so they required more energy to do their activities so their muscles cells have large number of mitochondria to provide more energy for their activities.
