Answer:
46 chromosomes.
Explanation:
In mitosis, two daughter cells separate from the parent cell, which has 46 chromosomes. In the prophase, the parent cell duplicates its own chromosomes to create two identical cells.
Each daughter cell should have the same number of chromosomes as the parent.
Answer:
The cell will possess an identical and full set of 46 chromosomes, or 23 pairs of homologous chromosomes.

Russell and Marco are trying to lift their friend Colin onto a tree branch. Russell is pushing
Colin upward with a force of 250'N. Marco is pushing Colin upward with a force of 310 N.
Earth's gravity is pulling Colin downward with a force of 520 N.
Assume all other forces on Colin are balanced. Which statement describes the forces on
Colin?
The forces are balanced, so there is no net force on Colin.
The forces are unbalanced, so there is a net force on Colin.
Answer:
Unbalanced
Explanation:
The forces acting upon Colin, his friends pushing and gravity, are unbalanced
How does a hot day affect enzyme activity during photosynthesis?
Answer:
At higher temperatures, more collisions occur so the rate of reaction increases. However, extremely high temperatures disrupt the shape of the active site, which will reduce itsactivity, or prevent it from working. Theenzyme is now denatured . Enzymestherefore work best at their optimum temperature.
The rabbit population in an ecosystem has grown past it's carrying capacity. What are two things that may happen naturally to bring the rabbit population back under control and how would these things control the population? (Must be at least 2 COMPLETE sentences
Answer:
One of the two things that could bring its population back down is lack of food, This is because due too the boom of the rabbit population their food sources will be eaten at a much faster rate until it overtime runs out. Another one is more predators, because of more rabbits more predators will be drawn too the area and help with population control by eating/killing them.

Rosa drew a flow chart of the carbon cycle. Flow chart of the carbon cycle with 4 boxes connected by arrows. Box 1: carbon dioxide in the atmosphere. Box 2: X. Box 3: consumers eat producers. Box 4: Y. The arrow that follows box 4 connects to box 1. Which labels best complete the flow chart?
Answer:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
Explanation:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
(b) X: Decomposers return carbon to the soil and release waste. Y: Producers undergo photosynthesis.
(c) X: Decomposers take in carbon dioxide. Y: Producers absorb carbon through their roots.
(d)X: Producers absorb carbon through their roots. Y: Decomposers take in carbon dioxide.
Box 2 (X) would be the process through which producers fix carbon dioxide to produce their own food, the carbohydrate. The process is otherwise known as photosynthesis and can be represented by the following equation:
[tex]6CO_2 + 6H_20 --> C_6H_1_2O_6 + 6O_2[/tex]
Box 4 (Y) would be the process of decomposition. Both producers and consumers eventually die and decompose in the soil. During this process, some of the carbon returns to the soil as organic matters while the process of microbial decomposition releases carbon dioxide into the atmosphere.
The correct option would be (a).

The distinct characteristics of different cell types in a multicellular organism are produced mainly by the differential regulation of the genes.
What is gene regulation?Genes are responsible for the synthesis of protein molecules in the cell.
All the cells of a living organisms contain the same sequence of genes, however, they differ in the way they are expressed.
This makes cells exhibit different characteristics in the same living organism.
Therefore, the distinct characteristics of different cell types in a multicellular organism are produced mainly by the differential regulation of the genes.

The half-life of uranium-328 is about 4.5 billion years. After four half-lives have passed, what fraction of the original sample will be left?
Uranium-238 decays very slowly with a half life of 4.5 billion years. what percentage of a sample of uranium-238 would remain after 13.5 billion years?
The mass of Uranium halves every 4.5 billion years, so 13.5 billion years= 3 half-lives.
[tex]M=M_{0}[/tex] × [tex](\frac{1}{2} )^n[/tex]
Is the equation that describes the decay, where [tex]M^0[/tex] is the initial mass and [tex]n[/tex] is the number of half-lives passed.
So if 3 half-lives have passed:
[tex]M=M_{0}[/tex] × [tex](\frac{1}{2} )^3[/tex]
[tex]M=M_{0}[/tex] × [tex](\frac{1}{8} )[/tex]
[tex]M= \frac{1}{8} M_{0}[/tex]
So there will be 1/8 of the original mass left after 13.5 billion years, or 12.5% of the mass left.

why you SHOULD NOT drink salt water if stranded at sea.
Answer:
Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly.
Answer:
The salt water will make you go lose your mind,and it will dehydrate you.

What are two ways that different species can divide up resources?
Answer:The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Thus, if a person has phenylketonuria, they have inherited genetic information that has lead to the production of a dysfunctional protein, specifically a(n) enzyme that normally breaks down phenylalanine.
What is phenylketonuria?Phenylketonuria is a rare genetic disease characterized by the presence of a mutation responsible for altering the function of an enzyme in the body responsible for converting the amino acid phenylalanine into tyrosine, which leads to the accumulation of phenylalanine in the blood, which in large concentrations is toxic to the human body.
With this information, we can conclude that DNA is inherited directly from the parents of an organism, through its gametes, which are produced by the process of Gametogenesis. So, if a person has phenylketonuria, they have inherited genetic information that led to the production of a dysfunctional protein, specifically an enzyme (n) that normally breaks down phenylalanine.

A mutation occurs during protein synthesis. How will the protein produced be affected? A. Since the mutation causes a new code for a better amino acid, the protein will still function normally. B. Since the mutation causes a new code for the same amino acid, the protein will still function normally. C. Since the mutation causes a new code for a better amino acid, the protein will be more powerful while performing its function. D. Since the mutation causes a new code for the same amino acid, the protein will be more powerful while performing its function.
Answer:
A mutation during protein synthesis may not affect the protein since the mutation causes a new code for the same amino acid, the protein will still function normally.
Explanation:
Protein synthesis depends on the transcription of DNA to RNA, and on the sequence of nucleotides in the chain, determining the triplets or codons that encode a specific amino acid.
In protein synthesis, when a mutation alters the codon, changing one nucleotide for another, it is possible that the mutation does not alter the amino acid and the protein functions correctly. This is because an amino acid can be encoded by several codons, as occurs with leucine, which is encoded by CUU, CUC, CUA and CUG.
The other options are not correct because one mutation does not give better amino acids or more powerful proteins.
A school bus transporting students to school is an example of
a
potential energy because it has the ability to take the students to school
Ob

Ос
potential energy because it is taking the students to school
O d
kinetic energy because it is taking the students to school
Answer:
2.kinetic energy because it has the ability to take the students to school.
Explanation:
Energy of a given system due to the virtue of the motion of the given system is known as kinetic energy of the system
now we know that
so kinetic energy depends upon mass of the system and the velocity of the system.
So here since bus is in motion and moving towards the school so the bus along with all the children must have kinetic energy in it
So here correct answer would be
2.kinetic energy because it has the ability to take the students to school.
