All human body cells contain 46 chromosomes. However, sperm cells in men and egg cells in women have only 23 chromosomes. This is due to meiosis. How does meiosis accomplish the reduction in chromosomal number?
Answer:
Two cell divisions after DNA replication
Explanation:
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.
Why does PE = mgh equal PE = Fw h ?
Answer:
Why is potential energy MGH?
Potential energy is energy an object has because of its position relative to some other object. ... For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Why must the bonds of these molecules be broken before anything else happens?
Answer:
Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.
Explanation:
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. Chemical reactions can occur spontaneously or require an outside trigger such as an input of energy. Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.
Why the bonds of molecules are broken?Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.
Chemical reactions create and destroy the chemical bonds that hold molecules together, creating new materials as their end product. Chemical reactions can start on their own or need an outside trigger, like an energy input. Chemical reactions can be endothermic or exothermic in that breaking chemical bonds takes energy while creating new ones releases it.

Which of the following processes produces the most ATP? a aerobic respiration b glycolysis c alcoholic fermentation d lactic acid fermentation
Answer:
b) glycolysis
Explanation:
Up to 36 ATP can be produced from one glucose molecule through aerobic reactions. Therefore, option (A) is correct.
What is aerobic respiration?Aerobic respiration supplies energy to fuel all cellular functions. The reactions result in the production of ATP, which can then be put to use to power other life-sustaining processes, such as growth, repair, and maintenance.
The release of energy that was stored in carbohydrates and lipids during photosynthesis and the subsequent availability of that energy to living organisms is the purpose of the series of enzyme-controlled events known as aerobic respiration.
Glycolysis, the Krebs cycle and respiratory electron transport contribute to the production of 36 ATP for every molecule of glucose that is used up during aerobic cell respiration.

Which student, if either, is most correct in their claim regarding the ATP/ADP cycle?
A. Brianna's claim is correct - the removal of a phosphate group (or the breaking of
a chemical bond) supplies a great deal of energy from the cell and the ATP/ADP process is not continuous.
B. Neither student is completely correct. Oscar is correct in that this process is a
cycle and Brianna is correct in that the removal of the phosphate group supplies the most energy

ATP can convert to ADP during ___________.
Answer:
phosphorylation
Explanation:
ATP usually releases energy by breaking down the weak phosphate cell present. The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.
Answer:
phosphorylation

James is conducting an experiment to test the effect of insecticides on frogs. He gives one group of frogs 10 cc of the insecticide and 0 cc of the insecticide to the other group of frogs. After 5 days, the effects of the insecticide are collected. what is the independent variable and dependent variable
Answer:
Independent variable: amount of insecticide
Dependent variable: effects of insecticide on frogs
Explanation:
Dependent variable in a research experiment, is the variable that is being studied, tested and measured by the researcher, while the independent variable is the variable that causes the dependent variable to change, when it is varied.
In this case, the amount of insecticides that is varied in quantity, is the independent variable that the researcher manipulates, while the independent variable is the effects caused by these varied amount of insecticide on frogs, which is tested and measured.
what else is needed to make glycine (amino acid) from a molecule of glucose? Where do you think that comes from
Answer:
certain amino acids are made of different things but heres overall carbon hydrogen oxygen and nitrogen
Explanation:
Glycine is a naturally occurring/formed amino acid found in humans, the difference between glycine and other amino acids is that it can be found in parts of protein structures in humans and can also be found in several foods consumed by humans like Sugar Cane, meat , and dairy products. glycine also has a hydrogen side chain which is absent in other amino acids.
Hence we can conclude that To make glycine ( amino acid ) from glucose ; Oxygen, carbon or hydrogen is needed and they come from the consumption of Protein-rich food and from respiration.

them.
Answer: Haiti is mainly know for their minerals! the main minerals extracted are: cooper, silver, and GOLD. Haiti has many many gold farms, markets, etc. HOWEVER this is a very poor area, as people here live off of only about 2 dollars per day. They could take this wealth and put it towards the people, roads, and construction, as they had an earthquake that killed many many people, and destroyed much. If you mean what they do with gold, they take the gold from farms, and mine it underground. They then sell it for money as this is a poor area as said before!

Answer:
- the discovery of the Pangaea Theory.
In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.

predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein
Full Question Attached
Answer:
The substance would be less likely to enter the cell by active transport or might enter more slowly
Explanation:
The information in the question suggests substance L is moving into the cell by active transport. We can tell this because the concentration of substance L inside the cell is 120 mM. However, the substance is still entering the cell from a lower to a high concentration, against its concentration gradient. This requires energy and is therefore active transport.
If there was a large protein attached, the active transport machinery might not be able to move substance L at the same rate. The rate it enters the cell might slow down, or it might stop all together. It might need to enter via another mechanism, such as endocytosis.
