Products enter a reaction and reactants come out of a reaction true or false?
Answer:
[tex]\boxed {\boxed {\sf False }}[/tex]
Explanation:
In a chemical reaction, the products are produced. The reactants are the substances that react.
In a chemical reaction equation (with the arrow pointing right) the reactants are on the left and the products on the right.
[tex]reactants \rightarrow products[/tex]The reactants enter and the products come out.
So, the statement given - products enter a reaction and reactants come out - is false and it is actually the other way around.

Which of the following is true regarding glycolysis ?
Choose 1 answer.
A.) It requires glucose as a reactant.
B.) It produces 36 ATP.
C.) It occurs in the mitochondria.
D.) It is an aerobic process.
Answer:
I would have to say A
Explanation:
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. So we already know that it uses glucose because thats what its breaking down. Glycosis produces 2 ATP so B is wrong. Glycolysis happens in the cytoplasm so C is wrong. Finnaly aerobic is using free oxygen in the process of the reaction. However glycolysis uses no oxygen and is anaerobic.
Glycolysis requires glucose as a reactant.
• Glycolysis refers to a cytoplasmic pathway that dissociates glucose into the three-carbon compound and produces energy in the form of ATP.
• The process of glycolysis takes place in the cytoplasm.
• In the process, the net production of 2 ATPs takes place.
• It can be both anaerobic and aerobic process.
• The process of glycolysis completes in 10 steps, five of which are in the preparatory phase and the rest 5 are in the pay-off phase.
• The process of glycolysis is used by all the cells of the body to produce energy, and the final product of glycolysis is pyruvate.
Thus, correct answer is option A, that is, it requires glucose as a reactant.

Which of the following statements is Newton's 1st Law of Motion? A. The object will move in the direction of the unbalanced force. B. Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.
Answer:
C.
Explanation:
thats just his first law of motion
Answer:
C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.
Explanation:
In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.

Answer:
So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.
Explanation:
In guinea pigs, for the characteristic hair length, short hair is the dominant allele and long hair is the recessive one.
In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:
P: Ss X Ss
Alleles S s
S SS Ss
s Ss ss
Where the offspring is:
50% Ss with short hair phenotype 25% SS with short hair phenotype 25% ss whose phenotype would be long hair.According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a green offspring?
Answer:
yy
Explanation:
it can only be yy because you need 2 recessive genes to show a recessive trait.
A plant with Yy genes could pass the recessive genes on, but would still show the dominant trait.
The possible genotype of the green offspring is yy, i.e., recessive one and will express only in absence of dominant allele.
What is genotype?In a broad sense, the word "genotype" refers to an organism's genetic makeup; in other words, it describes an organism's entire set of genes.
In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.
A genotype is a classification of the type of variant found at a specific location (i.e., a locus) in the genome.
Symbols can be used to represent it. For example, the letters BB, Bb, bb could be used to represent a specific variant in a gene.
In the given scenario, Y is dominant allele which will express in combination with y means the recessive one.
Thus, for expressing the green allele, it should be yy.

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

Cells are often compared to factories. How is a factory a useful model for explaining the cell?
Answer:
Each organelle within the cell has its own important job, similar to factory workers. Every organelle plays an important role and without one, the whole team loses function.
Cell is the basic unit of life. Cells unite together and forms tissue. Many tissue will unite and form organ. Organ will unite together to form a organ system.
What is cell?The building elements known as cells make up all of these plants and animals, including worms in the soil, horseflies on farms, lemurs in the jungles, reeds in ponds, and trees in forests.
Similar to these instances, many live organisms are composed of numerous cells working together. However, certain forms of life, such as the various bacterial and protozoan species, are made up of simply one cell.
Most cells, whether they are solitary or a component of a multicellular organism, are too small to be seen without a light microscope.
Therefore, Cell is the basic unit of life. Cells unite together and forms tissue. Many tissue will unite and form organ. Organ will unite together to form a organ system.

D. angiosperm
An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.
What are angiosperms?Angiosperms, that are also known as flowering plants, have “seeds” that are sealed off within an “ovary”, while gymnosperms do not have fruits or flowers and have uncovered seeds on the surface of leaves. Seeds of gymnosperms are often arranged as “cones”.
The features and characteristics that distinguish angiosperms from gymnosperms are fruits, flowers, and “endosperm” in the seeds. Examples of “Angiosperms” are “monocots” like orchids, lilies, agaves, grasses and dicots like, peas, roses, sunflowers, maples and oaks. “Gymnosperm” examples include “non-flowering evergreen” trees like pine, fir and spruce.
