Which chemical equation is balanced to show that matter is conserved during the reaction? *
Answer: Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.

during which stages of the cell cycle does a chromosome consist of two identical chromatids
Answer:
Anaphase
Explanation:
each chromosome is composed of two chromatids
Answer:
Throughout inter phase, nuclear DNA remains in a semi-condensed chromatin configuration. In the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome-sister chromatids- that are firmly attached at the centromere region.

Read God's rules of health and sanitation for Israel in
Lev. 11:1-8 and Deut. 23:12-14. How might these
rules have protected His people from diseases such as
those caused by parasitic worms? Relate your answer
to the mode of transmission of many parasitic worms.
Answer:
It is transmitted in the body through contaminated food.
Explanation:
These rules of God's about health and sanitation have protected Israeli people from diseases which was caused by parasitic worms because these parasitic worms entered the body by not washing hands and contaminated food. These parasitic worms are present on the skin as well as in the food so the person can save itself from these parasitic worms if he or she wash hands properly before eating the meal and eat clean, fresh and healthy food.

What kind of inheritance do you think the trait for the pedigree shows
Answer:
The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked. To start reading a pedigree: Determine whether the trait is dominant or recessive. If the trait is dominant, one of the parents must have the trait.

When humans perspire, water, urea, and salts containing sodium are removed from the blood. Drinking water during extended periods of physical exercise replenishes the water but not the sodium. This increase in water dilutes the blood and may result in the concentration of sodium dropping low enough to cause a condition known as hyponatremia. Symptoms of hyponatremia include headache, nausea, and lack of coordination. Left untreated, it can lead to coma and even death. The body has a variety of feedback mechanisms that assist in regulating water and sodium concentrations in the blood. The kidneys play a major role in these mechanisms, as they filter the blood and produce urine. The best way to reduce the symptoms of hyponatremia would be to
Answer:
The best way to reduce the symptoms of hyponatremia is to replace the body's sodium.
Explanation:
As seen in the question above, sweating causes the body to lose water and salts, such as sodium. We know that the excess of sodium in the body is harmful, however, the lack of sodium is also harmful, and can cause hyponatremia.
The loss of water in sweating can be reversed with water intake, but the loss of sodium must be reversed with sodium intake and the best way to do this is by eating salty foods. Sodium is one of the components of the salt used in the preparation of foods. In that case, when an individual eats salty foods, after having lost sodium molecules in perspiration, he will be replacing the lost sodium.

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?
186
214
158
200
172
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.

Which best describes how to classify water?
A It is an element because it is made
from a pure substance.
В
It is a compound because it is made
of a single kind of molecule.
© It is a mixture because it is composed
of more than one molecule.
D It is a solution because it is a
homogenous mixture of different
compounds.
Answer:
D
Explanation:
Water is a compound and scientifically known as H[tex]_{2}[/tex]0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...
Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.D (yay!) because it is not the *most* accurate, but simply the best description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.Ngl this was tricky, but I hope this helps :)
Jesssica is blood type A and her husband Graham is blood type O. She is worried because they are pregnant and their future child has a rare disorder which will require him to need regular blood transfusions. Jessica worries that if their son ends up with type O blood, like his father, it will be hard to get the necessary regular blood transfusions because people with O blood can only accept O blood. What is the likelihood of their child having blood type O?
Answer:
- 50% probability if Jessica has genotype "iAi"
- 0% probability if Jessica has genotype "iAiA"
Explanation:
Blood group in humans is controlled by multiple alleles namely; iA, iB and i. iA and iB are codominant but both dominant over i. The following blood types and their respective genotypes are possible;
- Type A: iAiA or iAi
- Type B: iBiB or iBi
- Type AB: iAiB
- Type O: ii
According to this question, Jessica is blood type A (iAiA or iAi) and her husband Graham is blood type O (ii).
- If Jessica has a genotype iAi, the probability that they will give birth to a child with blood type O (ii) is 50% (see punnet square)
- If Jessica has a genotype iAiA, the probability that they will give birth to a child with blood type O (ii) is 0% (see punnet square).
What is the last phase of the Cell Cycle? (This is when the genetic material has already been duplicated and what is left to do is to physically split up the rest of the cell - organelles, cytoplasm, etc. - into two separate, identical cells.)
Answer: mitotic phase
Explanation:
The cell cycle has two phases the Interphase and mitosis. Interphase is the growth phase where the cell prepares itself for the cell division. It is divided into three phase G1 phase( Cell growth),S phase ( DNA synthesis) and G2 phase(cell growth).
Mitotic phase has a multiple steps this is where the duplicated chromosomes are aligned or arranged, separated, and move into two new, identical daughter cells(cytokinesis)
The first step in the mitotic phase is called karyokinesis or nuclear division where the chromosomes are separated and move in opposite direction and the second portion of the mitotic phase, called cytokinesis which is the physical separation of the chromatids into the two daughter cells.

Explain and illustrate using chemical pathways how excessive alcohol intake can lead to; 1.Hypoglycemia
Answer: Alcohol can influence the blood sugar levels causing hypoglycemia.
Explanation:
Hypoglycemia is a condition in which the body experiences low blood sugar levels. Alcohol abuse can be one of the reasons for hypoglycemia. The occasional drinkers are affected negatively by this. It increases the secretion of insulin hormone which is a hormone necessary for keeping a balance of blood sugar levels in the body. The excess secretion of insulin can lead to decrease in blood sugar concentration and resulting in hypoglycemia. This can lead to type 1 diabetes.
