If a client is in a hypertrophy-based phase, how many repetitions should be programmed?
A. 2-4 reps
B. 12-15 reps
C. 1-6 reps
D. 8-10 reps
Answer:
The correct answer is option B. "12-15 reps".
Explanation:
The hypertrophy-based phase is a type of workout where the client aim is to gain muscle, achieved by the recruitment of new muscle fibers result of increased levels of tension applied to the muscular area. If a client is in a hypertrophy-based phase she or he should perform several repetitions in order to obtain the tension needed to gain muscle, from 12 to 15 repetitions are usually a good number.
Hypertrophy refers to the condition in which the muscle tears from the repetitive contraction of muscles.
The correct answer is:
Option B. 12-15 reps
The hypertrophy-based phase refers to:
1. If a client wants a hypertrophy-based phase, then the client wants to gain muscles due to repeated contraction of muscle fibers.
2. The client must do 12-15 reps of the maximum weight within the capability. It leads to microscopic tears in the muscle fibers, which result in the gaining of muscle.
Thus, the correct option is B.

Which biomolecule is represented in this example?
Answer: The biomolecule is a protein (more exactly, an enzyme) called tyrosinase.
Explanation:
First, a biomolecule is a molecule present in living organisms, we usually can separate them into 4 groups:
Carbohydrates, lipids, proteins, and nucleic acids.
Ok, albinism is the lack of melanin pigment (and the incapacity of producing it)
The first step to synthesize melanin is the conversion of tyrosine to dihydroxyphenylalanine, catalyzed by an enzyme called tyrosinase, then the lack of the biomolecule causes albinism.
Then here we are talking about an enzyme, and enzymes are proteins that work as biocatalysts.
Then the biomolecule represented in this example is a protein.

What Is the variable that stay the same in experiment
Answer:
The Constant
Explanation:
Answer:Independent Variable
Explanation:
Because it's independent and doesn't depend on something else.
In a cross of Limnaea, the snail contributing the eggs was dextral but of unknown genotype. Both the genotype and the phenotype of the other snail are unknown. All F1 offspring exhibited dextral coiling. Ten of the F1 snails were allowed to undergo self-fertilization. One-half produced only dextrally coiled offspring, whereas the other half produced only sinistrally coiled offspring. What were the genotypes of the original parents?
Answer:
the genotypes for the original parents must have been Dd x dd
Explanation:
Maternal inheritance refers to those cases in which certain phenotypic traits depends on the maternal genotype, independently of the individual genotype. In a cross, the genotype follows the Mendelian model, but the phenotype is influenced by the maternal genotype. The phenotypic traits of generations F1, F2, F3, and so on, do not correspond to the expression of their own genes, but ti the expression of the maternal genes.
Maternal inheritance has been studied in the Lymnaea species. In gasteropods, the dextral coil is clockwise, while the sinistral coil is counter-clockwise. Dextral is expressed by the dominant allele (D), while sinistral is expressed by the recessive allele (d).
In the exposed example:
The snail contributing the eggs (females) was dextral but of unknown genotype --> D-Both the genotype and the phenotype of the other snail are unknown.All F1 offspring exhibited dextral coilingIn the F2, One-half produced only dextrally coiled offspring, whereas the other half produced only sinistrally coiled offspring.Cross)
Parental) D- x --
F1) 100% dextral (The whole progeny exhibited the dextral trait because the
individual that contribute the eggs was dextrally coiled)
F2) 50% dextral
50% sinistral
The fact that the F2 expresses 50% sinistral and 50% dextral means that one of the progenitors that contributed with the eggs (female) must have had at least one of the dominant allele D for the dextral trait, while the other female must have had the recessive genotype dd for the sinistral trait.
So the genotypes for the original parents must have been Dd x dd
1st Cross:
Parental) Dd x dd
The snail contributing the eggs Dd
the snail contributing the sperm dd
F1) 2/4 = 1/2 Dd
2/4 = 1/2 dd
100% expressing dextral coiling
2nd Cross:
Parental) Dd x Dd dd x dd
F2) 1/4 DD 100% dd
2/4 Dd 100% Sinistral coiling
1/4 dd
100% Dextral coiling
50% of the F2 exhibited dextral coiling, while the other 50% exhibited
sinistral coiling
The ________ is the particle in the nucleus with a positive charge
Answer:
Protons
Explanation: Protons are particles in the nucleus. They give off that positive charge.
If water molecules surround a solute particle with their oxygen ends all pointing to the solute particle, what can you conclude about the charge of the solute particle? Is it positive, negative, or neutral, and how do you know?
Answer:
It is +
Explanation:
Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen. So your solute would attract the opposite charge which is the Oxygen
Polar water molecules have partial positive hydrogen charges and partial negative oxygen charges. Thus, oxygen would attract your solute having positive charge.
What is polarity?Polarity is the separation of electric charge that occurs when a molecule or its chemical groups have an electric dipole moment. This results in the molecule or chemical group having one end that is positively charged and one end that is negatively charged. Because of the disparity in electronegativity between the atoms that are linked together, polar molecules are required to have one or more polar bonds.
Polar water molecules have partial charges in both the hydrogen (positive) and oxygen (negative) directions, though mostly in the hydrogen's favor.
Therefore, oxygen would be attracted to your solute if it had a positive charge.

Which of the following describes the difference between the motion of liquid water and water vapor?
A. The particles in the liquid do not move, but the particles in a gas can move back and forth.
B. The motion of the particles is the same in both states, but they move slower in the gas state.
С. The particles in a gas can slide past each other, while the particles in a liquid are locked in place.
D. The particles in a liquid can slide past each other, while the particles in a gas are free to move in all directions.
The particles in a liquid can slide past each other, while the particles in a gas are free to move in all directions. So the correct option is D.
What is the motion of liquid particles?
Particles in liquids are dispersed randomly across the container and are relatively near to one another. Due to the closer proximity of the particles, collisions between them happen more often than in gases even if particles are moving quickly in all directions. The particles travel more quickly as the temperature rises, gaining kinetic energy along the way, leading to higher collision and diffusion rates.
The particles in a solid are arranged neatly and orderly, packing together as closely as they can. The particles are locked together too tightly to allow for movement from one location to another, yet they do vibrate in relation to where they are located within the framework. The particles gather kinetic energy and vibrate more quickly and vigorously as the temperature rises.
Therefore the correct option is D.

Give an example of a endangered species due to invasive species and EXPLAIN why it’s in danger
Answer:
Explanation:
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species.
Human health and economies are also at risk from invasive species. The impacts of invasive species on our natural ecosystems and economy cost billions of dollars each year. Many of our commercial, agricultural, and recreational activities depend on healthy native ecosystems.
What Makes a Species "Invasive"?
An invasive species can be any kind of living organism—an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism’s seeds or eggs—that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health. Species that grow and reproduce quickly, and spread aggressively, with potential to cause harm, are given the label “invasive.”
An invasive species does not have to come from another country. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake in Wyoming because they compete with native cutthroat trout for habitat.

The weights on the skateboard b. The height of the ramp c. The speed of the skateboard down the ramp d. The size of the skateboard wheels Clear my choice
Answer:
d. The size of the skateboard wheels
Explanation:
In an experiment, the independent variable is the variable that the experimenter manipulates or changes intentionally in order to effect a measurable response in another variable.
In this experiment, size of the wheels are changed and the resulting speed of the skateboard down a ramp is measured. This means that the independent variable is the SIZE OF THE SKATEBOARD WHEELS because it is what the experimenter changes to determine the speed of the skateboard (dependent variable).
