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.
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.

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.

When Alfred Wegener first noticed that the continents fit together like puzzle pieces, this was
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.

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.

Identify minerals extracted in Haiti
and describe what is done with
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!

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?
Answer:
Longshore current.
Explanation:
A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.
The energy released by the wave at shore produces a current which is referred to as a longshore current.
Answer:
It would be Longshore Current

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.

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

Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when
the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes
for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to
move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.
Donna records her data.
The missing part of the question is as follows:
Position Time (seconds)
1 23.23
2 21.56
3 20.33
4 19.00
5 18.02
Hypothesis: ____________
Dependent Variable: ____________
Independent Variable: ________________
Constants: __________
Control Group:_________________
Experimental Group: ____________
Answer:
Hypothesis:
if the weight is lowered the pendulum will move faster
Dependent Variable:
Time it takes the pendulum to swing or move
Independent Variable:
the position of the weight
Constants:
same weight and the same number of swings
Control Group:
pendulum at the lowest position
Experimental Group:
different height of pendulums
Explanation:
A hypothesis is a possible explanation for the observation in a given experiment which is "if the weight is lowered the pendulum will move faster" as it states the effect of length of the pendulum on the time it takes to swing.
The dependent variable in an experiment is affected and measured to see the effect which is the time it takes the pendulum to swing or move which is measured here and affected by the independent variable that is the position of the weight.
Constants are the variable that remains constant throughout the experiment that is the same weight and the same number of swings. Control group is the group of subject or condition which minimize the effect of factors or variables except one factor to compare or ensure if the experiment works that are pendulum at the lowest position. The experiment group is the group of a subject that get treatment desired to influence the dependent variable that is the different height of pendulums.
