Answer:
A. mRNA stand, nucleus
Explanation:
Transcription is defined as the process of copying DNA. This happens so that the cell can produce the proteins necessary for basic life functions.
DNA cannot simply be taken out of the nucleus that easily. So, the DNA must be copied into a different form. That's what RNA is for, specifically mRNA.
mRNA stands for "messenger RNA", which is a copy of DNA that can be transported outside the nucleus and be read to produce proteins in ribosomes.
Transcription happens in the nucleus, where the DNA is housed in. It can't be located anywhere else anyways since DNA cannot leave the nucleus.
Therefore, our answer is A.

3. Habitat Destruction
5. None of the Above
Explanation:
Answer:
1. d
2.c
3.a
4.a
5.d
Explanation:
1. Forests ecosystem have high biodiversity
3.Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
4.It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count.
5. Im not sure.
It may be ans c. As Trees absorb toxic chemicals through their stomata, or 'pores', effectively filtering chemicals from the air.
por que un globo con aire se agranda al sol y se achica en la heladera
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.

How is WHAM related to Nucleic Acids?
Answer:
Nucleic acid is an important class of macromolecules found in all cells and viruses. ... Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Explanation:
A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults
A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.
Which of the following actions would help the skater reach the top of the other side of the half pipe?
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.
Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.
Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.
The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.
The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.
As the heat energy is lost to the surrounding environment, the skateboard loses velocity.
Bending down by the skateboarder will provide additional energy to make up for the lost energy.
Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.

Explanation:
Got the answer right on a quiz and reducing frictional force leads to many other contributing factors that makes the skateboarder reach the other side of the half pipe.
Use your knowledge of Protein Synthesis, and the provided chart, to identify the
correct Amino Acid sequence from the mRNA strand: AGUUGGUCUGUA
A: serine, tryptophan, serine, valine
B: aspartic acid, valine, leucine, asparagine
C: leucine, histinde, glutamic acid, leucine
D: serine, threonine, arginine, aspartic acid
Answer:
A: serine, tryptophan, serine, valine
Explanation:
Hi there!
Protein Synthesis is the process where proteins are created from DNA.
We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart
The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.
Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.
So we can break up the code into groups of 3, to make identifying the codons easier.
AGU UGG UCU GUA
Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.
The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.
Let's start with the first codon, which is AGU
The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)
The second codon is UGG.
The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)
The third codon is UCU
The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)
The fourth codon is GUA
The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).
That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A

Why does a fish die when taken out of water ? Give suitable reasons .
Plz It is urgent . ( If you spam I will report )
Woohoo
Answer:
Fishes have gills that are special to breathe only under water when it is takes out of water it dies
Answer:
They suffocate to death.
Explanation:
A fish's gills are richly supplied with blood capillaries and can readily absorb the oxygen dissolved in water. Their gills are not designed to take oxygen from the atmosphere. So, they do not get enough oxygen and they suffocate to death.
