Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

Explanation:
If a flower is wilting, which structure inside its cells lacks water?
vacuole
cell wall
carpel
chloroplast
Answer:
Vacuole
Explanation:
The central vacuole stores water in the cell and helps maintain water pressure, or turgor pressure, within the cell. The plant wilts because the central vacuole is empty and the cell is partially collapsed. Once the plant is watered and the central vacuole is full again, the plant will return to its normal position and appearance.

How does movement of the legs affect the gills of crabs?
Answer:
The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.

Explanation:
Select the statement that does not correctly describe the circulation of blood.
1)blood flows in two loops.
2)the ventricles contract simultaneously to pump blood outside the heart.
3)blood flows simultaneously into the atria.
4)the right side of the heart receives
blood and the left side pumps blood.
Answer and I will give you brainiliest
sorry im not sure this is correct but i think the one that is incorrect is
4) the right side of the heart receivesblood and the left side pumps blood.i will put the explanation just incase you want to choose the answer by yourself after knowing it. I hope you read this too..
Explanation1)Blood flows in two loops
This one is already correct if it happens in human heart circulatory system. Human's heart beat in two loops and this is really useful because of enough pressure to pump blood to the body. This two loops name is double circulatory system.However fish has single circulatory system where they only pump blood once. So this one also can be wrong but if the answer only one, this one can pass.2)the ventricles contract simultaneously to pump blood outside the heart.[✓]
This one already correct, the heart pump blood to the body through aorta and to the lungs through pulmonary artery.3)blood flows simultaneously into the atria.
This one also correct, because the blood come to the atria first to go to the left ventricle. Both of left and right ventricles are working simultaneously.4)the right side of the heart receives
blood and the left side pumps blood.
This one can be correct but also wrong. I choose this one wrong because there's no more explanation in this statement. The right side of heart can also pumps blood and left side of heart also can receives blood.The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs and also The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.Note for moderators that read this#Moderators please don't be mean, dont delete my answers just for approval from your senior or just to get the biggest moderation daily rank.
mRNA Codon chart Using the above chart, name the amino acid that is coded for by a strand of DNA: CCA O Alanine O Arginine Isoleucine O Proline
Answer:
[tex]\boxed {\boxed {\sf Proline}}[/tex]
Explanation:
We are given a codon (set of three nucleotides) and asked to find the amino acid it codes for.
There are a few types of charts that can be used, for example, the circular one attached starts in the middle and goes outward. Follow the sequence of the three letters from the center.
Another chart attached can be used. For this, we must find the intersection of the three letters. Located the 1st letter on the left, the 2nd on the top, and the 3rd on the right.
Based on both charts, proline is the correct amino acid.

Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.

In 6 sentences, Cellular & Physical Comparison. Tell me the differences between plants and animals.
Answer:
Plants have either no or very basic ability to sense. Animals have a much more highly developed sensory and nervous system. Animals give off carbon dioxide which plants need to make food and take in oxygen which they need to breathe. Plants cells have cell walls and other structures differ from those of animals.
