What would be the end result of mitosis if the DNA did not replicate during interphase?
Answer: If cytokinesis took place before mitosis, chromosomes would be divided haphazardly, resulting in a defective cell. ... If chromosomes did not replicate during interphase, each new cell would receive only half the information needed to function properly.
Explanation:
The Formation of the new cell from the old cell is called cell division.
There are two types of cell division, these are as follows:-
MitosisMeiosisThe formation of the new DNA from the old DNA is called replication. The enzymes responsible for the formation of the new DNA is called DNA polymerase.
During the cell division, the DNA doubles its amount at the S phase of the interphase. If in this phase the DNA will not duplicate then at the telophase one cell has no chromosome and become the case of the nullsomy.

Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.
Each week, a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.
What is the independent variable in this experiment?
Answer:
question 1 is 4. question 2 is 2. question 3 is 1. question 4 is 2. question 5 is 1=3 2=2 3=4 4=1. question 6 is 2
Nemo, a marine fish (adapted for life in the sea salt water ) is placed inside a freshwater aquarium. The next day, the owner finds that he has perished(died) in the tank! Why?
Answer:
The freshwater is hypotonic to the fish
Explanation:
A marine fish is adapted to living in water that is salty.
The fish will not survive because the freshwater would be hypotonic to the body of the fish and as such, excess water would enter its body which will lead to its death. The cells that make up the body of the fish will take-in excess water and lyse, leading to the death of the fish itself.

how do 2 siblings from the same parents look different to each other
Answer:
After all, kids get their genes from the same parents. But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.

In your own words, define or describe what you
already know about photosynthesis?
Answer: Okay so Photosythesis is the process used in most plants (except carnivorus plants) when the plant uses its chroloplasts (cells only plants have) to convert sunlight into sugar which makes food for the plant so it can live without having to hunt for food.
Explanation:
I hope this helps sorry if it doesn't :(
Have a good day :)
Stay motivated :)
Answer:
Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.

which two products are bromelain likely to produce when breaking down proteins
amino acids
fatty acid
monosaccharides
nucleic acid
polypeptides
disaccharides
The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.
What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.
In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

Don came up with the hypotheses that butterflies prefer to eat nectar from white flowers Don conduct an experiment and learn that his hypotheses with not correct what should Don do next
Answer:
B
Explanation:
A. Don should change the data he collected to make it look like the hypothesis was correct.
B. Don should test a new hypothesis.
C. Don should communicate the results of his experiment.
D. Don should hide his results so that nobody can see that he was wrong.
The correct thing for Don to do would be to test another hypothesis.
Hypotheses are generalized statements without any experimental tests. Once they are tested and are found not to be true, the next thing is to discard them.
A hypothesis that has been proven not to be true no longer serves any purpose. The next thing would be for Don to make and test a new one.
The correct option is B.
Answer:
Don should communicate the results of his experiment.
Explanation:
which statement accurately describes bioaccumulation:
1) a substance, such as a pesticide, collects in the body of an organism over time.
2) the concentration of a substance increases as it moves up the food chain
3) a method to get rid of an invasive species in an ecosystem
4) pesticides in the soil, air and water become sources of pollution.

In the box provided explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen
І
Answer:
Explanation:
Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.
Explanation:
Ten fish have lived in a 10-gallon fish tank for 6 months. However, within 2 weeks of adding 6 new fish, the population of fish drops to 7
fish. Which most likely accounts for this drop in the fish population?
A. The additional fish increased the water level.
B. The additional fish reduced the space per fish.
C. The additional fish increased the water temperature.
D. The additional fish reduced the carbon dioxide levels.
Answer:
I think it's D
Explanation:
Although space per fish is important, and may even be correct, I found D to be the most logical answer as each fish would need the same amount of carbon dioxide or the unbalance would cause a decrease in population.

In a healthy ecosystem, which trophic level should
have the most energy? Why? *WILL MARK BRAINLIEST*
Answer:
Producer(plants)
Explanation:
They can produce there own energy and they help all of the other animals stay alive.
in a healthy ecosystem, the trophic level that should have the most energy is the producer.
WHAT IS TROPHIC LEVEL:Trophic level of an organism refers to the position of the organism in the flow of energy in an ecosystem.Organisms feed on one another in an ecosystem to obtain energy needed for their metabolic activities.More energy is contained in lower trophic levels than that of higher trophic levels. This means that, according to this question, more energy will be in the producers as the lowest trophic level.Therefore, in an healthy ecosystem, the trophic level that should have the most energy is the producer.
