do you think all living organisms have the same types of cells why or why not
All organisms do not have the same number and type of cells because each one has different characteristics.
On Earth there are different types of organisms, some are complex like plants or animals, these are multicellular because they have a large number of cells.
However, all organisms are not the same. Some are characterized by having only one cell such as bacteria or algae.
On the other hand, not all organisms have the same type of cell. Some have prokaryotic cells, that is, cells that do not have a defined nucleus. Some examples of an organism with prokaryotic cells are:
BacteriaWhile cells that do have a defined nucleus are called eukaryotes, we can find them in animals, plants and humans.

Epithelial cells are specialized to protect,absorb and secrete substances as well as detect sensations....Why are nerve cells are used to carry information or impulses from one part of the body to another.
Answer:
those cells or tissues which form the covering of skin and various vital organs like heart (pericardium), lungs ( pluera ) and peritoneal cells are epithelial tissues .they may be ciliated and flagellated .due to this they help in movement of fluid in female reproductive tract .they also form the lining of nephron
those cells which are involved in generation and conduction of nerve impulse are called nerve cells. they do not provide any covering and protection

This principle states that alleles separate during gamete formation.
• A. Law of Independent Assortment
B. Law of Dominance
.
C. Law of Segregation
D. Law of Multiple Alleles
Answer:
c. low of segregation is the correct answer
This principle states that alleles separate during gamete formation is Law of Segregation.
Option C is correct.
How do we explain?The Law of Segregation states that during gamete formation, the alleles of a gene segregate (separate) from each other, so that each gamete receives one allele from each parent and this means that each gamete will contain only one of the two alleles for a particular gene.
The Law of Segregation was first proposed by Gregor Mendel in 1865.
Option C is correct.

Gases trap heat and cause the greenhouse effect. Solar radiation warms the earth, while the atmosphere traps it.
Leads to seasonal patterns, when the earth is tilted to the northern hemisphere its summer and when the earth is tiled to the south, its winter.
Results in some of the atmosphere to be warmer than other parts, it changes in volume and pressure which results in strong weather.
As wind or ocean current moves, the Earth spins underneath it.
Melting of the ice mass at the poles, which causes rising sea level, producing flooding and endangering coastal habitats

When can a cell swell up ?
Answer:
Explanation:
The cell swells up when the concentration of water molecules outside the cell is more than the concentration of water molecules inside the cell. It is because the water moves from a region of higher concentration to a region of lower concentration due to osmosis. So the water molecules outside the cell will move inside the cell ( from higher concentration to lower concentration) and it will swell up.
This solution is known as hypotonic.
So the correct option is B.
Hope this helps
plz mark as brainliest!!!!!!
Answer: A
Explanation: When there is a higher concentration of water in the cell more than the surrounding area, then the cell tends to swell up, this is due to osmosis.
Which of the following statements is true? The rigidity of a cell wall causes plants to be sedentary. Primary cell walls are more rigid than secondary cell walls. Since they have cell walls, plant cells do not have cell membranes. A wilting plant will have a full central vacuole.
Answer:
The correct answer is : The rigidity of a cell wall causes plants to be sedentary.
Explanation:
Plant cells have an extraordinary organelle present outside of cell membrane known as a cell wall, which makes the cell more rigid and strong. The primary capacity of a cell wall is to provide structural support.
It additionally gives the plant a specific level of inflexibility, which permits it to become extremely tall without falling under its own weight. The drawback is the absence of versatility Which is the reason plants are inactive and incapable to move.
Thus, the correct answer is : The rigidity of a cell wall causes plants to be sedentary.

Answer:
After Hugh analyzed his daughter’s DNA, he understood that her DNA had certain malfunctioning genes. He wondered whether those genes were responsible for this daughter’s condition. He also had these questions:
Can this condition cause significant harm to her health?
If so, what kind of health problems will she develop?
Are there ways to treat this condition?
Explanation:
After Hugh analyzed his daughter's DNA he thought that her DNA had certain malfunctioning genes. He thought those genes were responsible for this condition of his daughter.
What is DNA?DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.
Friedrich Miescher discovered DNA in the year of 1860.
The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA.
The shape of DNA is double helical structure.
Siblings share only about 50% of same DNA due to the reason of recombination.
The life span of DNA is 521 years.
Therefore, after Hugh analyzed his daughter's DNA he thought that her DNA had certain malfunctioning genes. He thought those genes were responsible for this condition of his daughter.

After one round of DNA replication, _____________ of the DNA will contain only 14N, _____________ of the DNA will contain only 15N, and _______________ of the DNA will be of an intermediate density.
Answer:
After one round of DNA replication, none of the DNA will contain only 14N, none of the DNA will contain only 15N, and all of the DNA will be of an intermediate density.
Explanation:
In order to rule out the conservative model of DNA replication and discover that it in fact a semi-conservative model, this technique was employed to check for what ratio of N15 and N14 was present in cells that had undergone the process of replication. The former would've resulted in equal densities of both N14 and N15.
