Answer:
all 20
Explanation:
It is impossible to know how many individuals will have the disease at the end without knowing other factors such as the condition where the subjects are being held, trial specifications and safety measures, etc. Based on the information provided, the best prediction that can be made is that all 20 subjects will have the disease. This is because since none of them are immune the disease will spread between the patients/subjects through contact or testing equipment.

Why is a supply of oxygen important for muscle contraction?
Answer:
For muscle contraction to take place oxygen is needed. ... Oxygen allows the body to convert glucose into ATP more efficiently without creating a waste product.
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. ... Whether you're exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP
ATP= Adenosine triphosphate

Answer:
The cell
Explanation:
The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is the cell.
This is in accordance with the cell theory which has three basic components, including:
1. The cell is the basic unit of life
2. All living organisms are made up cells
3. Cells arose from pre-exsiting cells.
Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.

clothes outside to dry.
Explanation:
Ap3x
Using extra energy-saving techniques, such as occasionally hanging clothes outside to dry them, could improve the solution of replacing outdated equipment with newer, more energy-efficient appliances. So, the correct option is B.
What are energy-saving techniques?Energy-saving technology, commonly referred to as green technology, is innovation that enhances upon or replaces current systems in order to save energy. Technology of this kind often helps operators save money while reducing the negative effects of human interference with the environment.
Instead of leaving appliances on standby, turn off the power source to conserve the maximum energy. As you leave the house or go to bed, turn off the heater, air conditioner, and other equipment. Turn off the computer and any other devices, including printers and Wi-Fi routers, at night or while we're away.
Using extra energy-saving techniques, such as occasionally hanging clothes outside to dry them, could improve the solution of replacing outdated equipment with newer, more energy-efficient appliances.
Therefore, the correct option is B.

Explanation:
Identical twins are produced from the same sperm and egg (which splits after the first mitotic division), whereas fraternal twins are produced from separate sperm and separate egg cells. If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answer:
This is 25%
Explanation:
Analysis, Since the dominant brown eyed parents produce blue eye child, this shows they are heterozygote dominant
However,this fraternal twin is not genetically identical, due to the blue eye color,(recessive) but the fact remain that they are the parents.(because he inherited the recessive allele from each of the parent)Therefore the probability is 25%.
This is because he is the only one out of the 4 kids( based on Mendelian fashion) this is 1/4,25%
Fraternal tweens are produced from different maternal and paternal gametes. The blue-eyed tween has 100% probability of transmitting the blue-eyes allele to the offspring, while the brown-eyed tween has 50% probability.
Available data:Fraternal twins are produced from separate sperm and separate egg cells.Brown eyes ⇒ Dominant traitBlue eyes ⇒ Recessive traitWe will name B to the dominant allele that codes for brown, and b to the recessive allele that codes for blue eyes.
So, the possible genotypes and phenotypes are
Gentoype Phenotype
BB Brown eyes
Bb Brown eyes
bb Blue eyes
Solving the problemThe parent with blue eyes must be only bbThe parent with brown eyes must be either BB or BbFor the twin boy to have blue eyes, he must have received two recessive alleles, one from the mother and one from the father.
So the father is heter0zyg0us for brown eyes, Bb.
Cross: Bb x bb
F1) 1/2 of the progeny is expected to be brown-eyed, Bb
1/2 of the progeny is expected to be blue-eyed, bb.
So we have two genotypes for the tweens, Bb and bb.
bbThe bb tween has blue eyes and is h0m0zyg0us recessive for the trait. So the probability that this fraternal twin will transmit the blue eye allele to his or her offspring is 100% This tween can only provide recessive alleles to his or her progeny. BbThe Bb tween has brown eyes and is heter0zyg0us for the trait. So the probability that this fraternal twin will transmit the blue eye allele to his or her offspring is 50% This tween can provide one dominant or one recessive allele to his or her progeny.So, the blue-eyed tween has 100% probability of transmitting the blue-eyes allele to the offspring. The brown-eyed tween has 50% probability of transmitting the same allele to the descendants.

Which of the following is not a method of heat transfer? Conduction Insulation Radiation Convection
Answer:
insulation is the correct answer
The method that is not one of the heat transfer method is insulation.
Heat transfer can be regarded a term in thermal engineering use to describe the generation as well as the use and conversion, exchange of thermal energy that exist between physical systems. Heat transfer can be done with different mechanismsThese are: conductionconvectionRadiationConvection can be regarded as the flow of heat in fluids, these fluids could be warmed gas, water.Conduction can be regarded as the movement of heat through objects that are in physical contact, like two metalsRadiation can be regarded as the energy which appears from a source then travels through space, this do contain wave-like properties. Insulation can be regarded as setting up a barrier between two objects, usually between hot and the cold object , so that heat reduction can be achieved.Therefore, Insulation is not heat transfer mechanism, it i a way to reduce heat loss.

Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Answer:
Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Explanation:
All the three options given can cause checkpoint genes to interrupt cell division.
Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.
Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
Answer:
The cells DNA has been damaged somehow and The cells DNA was replicated incorrectly
Explanation:
sometimes, these checkpoint genes are mutated or damaged and, thus, are unable to tell a damaged cell to stop dividing. When this occurs, the damaged cell gives rise to many damaged cells, which in turn create more damaged cells. These dividing cells form a NEOPLASM
Two solutions are separated by a semipermeable membrane that is permeable to potassium but not chloride or sodium ions. Solution A on the left contains a solution that is 100 mM potassium, while Solution B on the right has a concentration of potassium chloride of 1 mM. There is an electrode in both solutions, and a comparative assessment of voltages between the two compartments is being made. The investigator doing the study decides to call side B ground potential (or, in other words, defines it as 0).
A. What is the value for the chloride equilibrium potential in this condition?
B. In one sentence, describe why it has a positive or negative value. C. What would be the value of the chloride equilibrium potential? (show how you calculate this) D.
