Which of these statements about enzymes is true? Select
all correct answers.
a. Enzymes can help break chemical bonds.
b. Enzymes always change their shape when they bind
to a molecule.
c. Enzymes can break down a variety of different
substances.
d. An enzyme’s shape is related to the shape of the
substrate it binds to.
Answer:
b. Enzymes always change their shape when they bind to a molecule.
d. An enzyme’s shape is related to the shape of the substrate it binds to.
Explanation:
Enzymes are proteins that are secreted by special cells in living organisms. They are the organic catalysts of biochemical reactions.
The role of the enzyme in the enzyme catalyzed reaction is to bring reactants together on its surface so as to have better interactions.
Enzymes have the capability to fit the substrate into an induced fit position.
The process by which enzymes change shape in a reaction is called the induced fit.
This way an enzyme holds the substrate tightly for the reactions to occur.

What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.
Explanation:
An amniotic egg has a clump of nutrients that is used to sustain the embryo during development. This clump of nutrients is called the yolk, and the yolk sac encloses it.
Help!!! look at the picture!
Answer:
The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.
Explanation:
Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.
Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.
When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.

Which is part of microevolution?
Answer:
Microevolution is the change in allele frequencies that occurs over time within a population. This change is due to five different processes: mutation, selection (natural and artificial), gene flow, gene migration and genetic drift.
Explanation:
the grand canyon was carved, separating what had once been a single population of squirrel into two seperate populations. what do you think happened to those populations over time?
Answer:
They became different.
Explanation:
Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.

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.

The STARTING molecule for the Krebs cycle is
A.)NADH
B.)pyruvic acid
C.)glucose
Answer:
B
Explanation:
This combines with a 4 carbon compound to start the cycle
Kreb's cycle or Tricarboxylic cycle is an enzyme-catalyzed reaction, in which ATP molecules are generated. The starting material for the cycle is pyruvic acid.
The correct answer is:
Option B. Pyruvic acid
Some of the features of Kreb's cycle are:
The starting material of Kreb's cycle is pyruvic acid. The pyruvate is obtained from the glycolysis of glucose molecules.The pyruvic acid breaks into a two-carbon molecule and joined with the enzyme Co A, to form a two-carbon molecule Acetyl Coenzyme A.The Krebs cycle is a series of dehydration, reduction, oxidation, and hydration reactions.The product of Kreb's cycle is two carbon dioxide molecules, one GTP, and reduced NADH and FADH2.
Thus, the starting material for the Kreb's cycle is pyruvic acid, which is converted into the acetyl Coenzyme A before entering the Kreb's cycle.

effect of osmosis on cells....
Explanation:
Effect of Osmosis on CellsOsmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.
An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.
The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure.
#it is correct, please don't report
Effects of osmosis on cells
Red blood cells placed in a solution with the same water concentration as their cytoplasm (0.85 per cent salt solution) will not experience an overall change in volume. No osmosis occurs.Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up and burst.Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.Red blood cells placed in a solution with a lower water concentration compared to their contents (eg 1.7 per cent salt solution) will lose water by osmosis and shrink.Water will diffuse from a higher water concentration inside the cell to a lower water concentration outside the cell.Direction : Find a wordless photo that shows this law and explain why your image shows Newton’s first law.
