Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
To test various theories, experiments are typically conducted under a number of different conditions. Several variables must be established when planning studies to ensure reproducibility, precision, and validity of findings.
For example, while controls are held constant, different independent variables are strictly altered and analyzed - this ensures validity and may show whether external factors affected the experiment.
In this experiment, the rate of the reaction is the dependent variable. Thus all factors that may influence the final result, such as the temperature, pH, and enzyme concentration should be kept constant.
These factors can increase the reaction rate by altering the configuration of the enzymes, providing more collision energy, and increasing the collisions between and ratio of reactants. Increasing the concentration is expected to increase the frequency of collisions between reactants and thus speed up the rate.
The three variables that should be kept constant in the setup of the student's investigation:
temperature of the reactionpH of the reactionamount of enzymeCONSTANT VARIABLE:
In an experiment, a constant variable is that variable that must be kept constant or unchanged in order not to affect the outcome of the experiment. Constant variable is also called control variable. In this experiment, a student is investigating how substrate concentration affects the rate of an enzyme catalyzed reaction.The constant variable i.e. the variable that the student should keep constant are as follows:temperature of the reactionpH of the reactionamount of enzymeKeeping these variables above constant means not allowing temperature, pH or amount of the enzyme interfere with the experimental outcome.Learn more at: https://brainly.com/question/474060?referrer=searchResults

Answer:
im pretty sure it's the second option (external fertilization) and the last option (external development) because it said that they put sperm and eggs into the environment which therefore creates fertilized embryos that are free swimming and become part of the zooplankton. they are never being carried by the starfish so therefore it's all external. so external fertilization and external development.
Explanation:
can you help me explain the relationships between these terms photosynthesis, chlorophyll, thylakoids, chloroplasts
Answer:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Hope this helps!
Explanation:
Brainliest?
Answer:
Photosynthesis occurs in the chloroplasts, chloroplasts capture light energy, thylakoids can be found inside chloroplasts, where light-dependent reactions occur, chlorophyll is found in the thylakoids, chlorophyll absorbs light energy, and chlorophyll is what makes plants look green.

If a cell with little hydrogen peroxide begins producing a large amount, what will happen to the rate at which the hydrogen peroxide is broken down
Answer:
Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product. The result is an increasing amount of foam produced in your cup as you increase the amount of H2O2 in your reaction.

(50 points) Think about the renewing of cells in a human body. What would happen if new cells stopped forming when we reached maturity while old cells never died off? Then consider what would happen if new cells continued to form while old cells never died off?
Answer:
We would gradually decay, and it would be horrific, and if new cells contiued to form it would also be pretty horrific
Explanation:
If we reached maturity while old cells never died off , this would heighten the risk for genetic and hereditary disorders, and new cells are not formed through mitosis, and are unable to replace inefficient or cells with damages, whether it not be to the DNA or other organelles.This would cause a significant decline of production in our body, and would also cause cells such as your skin cells, to be at a heightened risk of genetic and hereditary disorders and diseases such as cancers and melanomas
If our cells continued to form while old ones never died off, if would also be very inefficient for our bodies, as the amount of energy and ATP required to support an ever-growing cell population of that size would leave us wanting to eat more and more each day to fufill our daily metabolic processes, leaving us skinny and weak.This would also cause a loss of some function in some areas, because some areas require more energy than others, such as your pulmonary and cardiovascular system, and could result in wasting of muscle tissure, as they would not be getting the nutrients needed
If new cells would stop forming once maturity is reached, and old cells would never die. Genetic disorders would be more common, cells with damage would not be replaced, hereditary disorders would also be more common, such as cancers and others. If new cells continued to form and old cells would never die off, the amount of energy that is required to normally support us would leave us wanting more food each day to achieve our metabolic process.

Geothermal electricity-generating plants are located in regions that often have
droughts
heat waves
volcanoes
tornadoes
Answer: volcanoes
Explanation: geothermal electricity- generating plants are most commonly located around the Ring of Fire, which is a hotspot for volcanoes.
Geothermal electricity-generating plants are located in regions that often have volcanoes. The correct option is c.
What is geothermal electricity?Deep below, hot water is pushed under strong pressure through a well. Therefore, the pressure decreases as the water reaches the surface. When water becomes steam.
A turbine that is connected to an electricity-generating generator is spun by steam. Electricity is produced by geothermal power plants by harnessing the thermal energy of the planet.
The steps that must be taken are as follows.
Deep below hot water is pushed under strong pressure through a well.The creation of thermal energy involves heating water and forcing it through a turbine.It is then transformed into electricity.A generator that aids in the generation of energy is activated by the steam rotating the turbine.Therefore, the correct option is c. volcanoes.

The offspring of a particular cross are 100 percent heterozygous for the trait of plant height. What were the most likely genotypes of the parents? Tt ´ tt Tt ´ Tt tt ´ tt TT ´ tt
Answer:
TT x tt
Explanation:
If the offspring of a particular cross are 100 percent heterozygous for the trait of plant height. the most likely genotypes of the parents is TT and tt.
HETEROZYGOUS:Heterozygosity is a condition in which the genotype of an individual consists of two different alleles of a gene.
According to this question, a gene coding for plant height is involved. The tall allele (T) is dominant over the short allele (t).
This means a heterozygous offspring will have the following genotype: Tt. This genotype will only arise totally i.e. 100% in the offsprings if the parents are both homzygous for the trait i.e. TT and tt.
