why are sister chromatids genetically identical
Answer:
They carry the same alleles, also called variants or versions, of genes because they derive from one original chromosome.
Explanation:
In a balanced ecosystem with predators and prey, if the prey population decreases then....?
Answer:
Predator population will also decrease
Explanation:
This is because the predators are dependent on their prey without the prey they would starve and die out so with less possible food the less of a population for what ever eats that prey which can lead to a chain reaction throughout the ecosystem however it is also the other way around too the more possible food the more chance for babies to be born and not starve to death.

What is density of a liquid with mass of 17.4 and a volume of 20 mL ? Would this liquid float or sink at room temperature based on its density and the known density of water?
Answer: The density of the liquid is 0.9 g/mL
. Hope this helps but I can not answer the second part. Hope that it is beneficial to you anyway! :)
(Edit) This might help you figure it out: The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
Explanation:
Answer:
i think it would float tbh

What would happen to an animal cell with an internal salt concentration of 2% if it were placed in a salt solution with a salt concentration of 20%? (It helps to draw a picture) *
a.The cell loses water because there is a higher concentration of water inside the cell.
b.The cell loses water by pumping it across the membrane with the use of ATP
c.The cell gains water because there is a higher concentration of water inside the cell.
d.The cell stays the same because water will not move across the cell membrane.

What can happen if a population of organisms disappears from the food chain in an ecosystem with low biodiversities, such as the tundra?
Answer: If the population of an organism dies out, then the animals on top of it on the food chain are going to die, since they will have no other food to rely on. Or, they will have to find a new source of energy if they do not.
This is why we should not try to kill any animals, even too much fishing can cause the same problem.
Hope this helps you!

Describe the use of enzyme for testing glucose in the urine of diabetics
Answer:
If too much glucose gets into the blood, the extra glucose will be eliminated through your urine. A urine glucose test can be used to help determine if blood glucose levels are too high, which may be a sign of diabetes.
what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s
Answer:
We can plug in the information for the ball into this equation to determine the kinetic energy. The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J
Explanation:
Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves.
The skin cells of a scorpion organize together to make a hard covering called a carapace, which helps protect the scorpion. What is the term for a group of similar cells working together?
Question 11 options:
system
organism
organ
tissue
The skin cells of a scorpion organize together to form a hard covering called a carapace, which helps protect the scorpion. "Tissue" is the term for a group of similar cells working together. The last option is the correct answer.
What is a tissue?In a single-celled organism, cells perform all of the body's functions, whereas in multicellular animals, cells join together to form tissue, tissue joins together to form organs, and organs join together to form organ systems, and all functions are divided. By the time zygote formation occurs, there is only one cell present, and that cell has been divided, specialized, and assigned specific functions.
Some cells make stem cells, some make epithelial cells, and so on. The tissue is a group of cells having a similar function, such as epithelial tissue, which has many cells but all of them perform the same function, that of a skin cell; all of them have sweat glands, etc.
Hence, "tissue" is the term for a group of similar cells working together. The last option is the correct answer.

What landform is created when 1 oceanic plate and 1 continental plate move apart at a Divergent Boundary?
Answer:
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary.
someone answer these 2 for me
Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.

Suppose a scientist developed a hypothesis stating that a certain substance slowed down the growth of chili pepper plants. Briefly describe a controlled experiment
the scientist could conduct to test the hypothesis. Identify the controlled variables, the independent variable(s), and the dependent variable(s).
Answer:
The experiment consists of three different treatments:
1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth
2- Fifty (50) no treated chili pepper plants that grown in normal conditions
3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)
Dependent variable: plant growth
Independent variable: the amount of substance x (suspected to slow down plant growth)
Explanation:
The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.
Hypothesis development for substance.
A hypothesis is a temporary or tentative arrangement or explanation that is made for the experiment on the basis of an assumption. The experiments highlight the development of certain substances that slowed down to the growth of the chili pepper plans.
Thus the answer is slow growth, normal growth, and positive fast growth.
The assumed experiment consists of 3 treatments. As the first (50) chili pepper plants treated with substance X tend to slow down the growth. The second plant shows a grown in normal conditions. The 3rd plant sows the slow down the growth (positive control).Thus the dependent variable is then planted growth and the independent variable is substance X.Learn more about the scientist's development.
