Answer:
One difference between the chromosomes of prokaryotes and those of
eukaryotes is that: chromosomes are in a nucleus in eukaryotic cells.
One difference between the chromosomes of prokaryotes and those of eukaryotes is that the chromosomes are in a nucleus in eukaryotic cells. Thus, the correct option is B.
What is eukaryotic cell?Eukaryotic cells are the organisms whose cells contain a well-defined nucleus and other membrane-bound organelles such as chloroplast and mitochondria. There is a wide range of eukaryotic organisms including animals, plants, fungi, and protists, as well as most of the algae. Eukaryotic organisms may be either single-celled or multicellular.
Eukaryotic chromosomes are located within the nucleus of the cell, whereas the prokaryotic chromosomes are located in the nucleoid. This is the key difference between a prokaryotic and a eukaryotic cell. The eukaryotic cells have a membrane-bound nucleus whereas a prokaryotic cell lacks a well-defined nucleus.
Therefore, the correct option is B.

• After a week pour off the acid.
Shake the bottle vigorously for two minutes.
• Filter the contents of the bottle into a dish of water.
• Leave the dish undisturbed for an hour.
• Put two heavy weights on the material in the dish for a week.
What does the student's experiment most likely demonstrate about the rock cycle?
A) Pressure can cause melting of rocks to form igneous rocks.
B) Pressure can crystallize dissolved rocks to form sedimentary rocks.
C) A series of steps can cause weathering of rocks to form sedimentary rocks.

What do we call the cells in phloem that are alive at maturity but lose almost all their organelles?
A. Sieve- tube
B. Tracheid's
Answer:
Sieve-tube
Explanation:
Sieve elements are thin-walled cells that are alive at maturity, although the protoplast is greatly changed, and they generally lack nuclei. Sieve elements are elongated and function as the basic photosynthate-conducting cell type in the phloem of vascular plants.

As you move from right to left on the periodic table, what happens to the number of protons and neutrons in atoms?
As you move across a period, the atomic mass increases because the atomic number also increases. When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom. The atomic mass for any given atom mainly comes from the mass of the protons and neutrons

2. How do cells produce new cells for growth and repair?
Answer:
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.
Explanation:
Answer:
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. ... Some organisms can use mitosis to reproduce asexually. The offspring of asexual reproduction are genetically identical to each other and to their parent.
Cells make copies by dividing into two cells in a process called mitosis. As the parent cell divides, it passes on its genetic instructions to both copies. The new cells look and function just like the parent. Eventually, each of the new cells will divide, too.
Dead cells can make new cells in order to grow and also to replace old dead cells. The process by which new cells are made is called cell division.

5. You are working for a Risk & Quality Design Company and are asked to compare the effect of two different fertilizers (Fertilizer A & Fertilizer B) on plant growth. Write the hypothesis statement, regarding this investigation, that would be included in your report to your boss.
Answer:
Explanation:
There are two major hypothesis used in scientific research; null hypothesis and alternate hypothesis. Null hypothesis is an hypothesis used in research that assumes that there is no difference between two variables or set of variables in a comparison. While alternate hypothesis is the hypothesis that is in consistent or agreement with the aim or title of an experiment.
In research, the most widely used type of hypothesis proffered in new research is the null hypothesis. The null hypothesis for the research described in the question is stated below;
There is no significant difference between the effect of the two fertilizers (fertilizer A and fertilizer B) on plant growth.
The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization please select the best answer from the choices provided a b c d
The energy in the pyramid is entropy as it helps in the energy transfer energy from the trophic level the correct option is energy is misplaced at every tropic stage as warmness and serves to growth entropy.
The strength glide via meals chain and meals webs comply with the second regulation of thermodynamics. At every tropic stage, the handiest 10% strength is surpassed in the following stage and relaxation 90% is misplaced as warmness. Therefore, strength switch via meals chains continually finally ends up with lesser usable strength. The strength misplaced in the surroundings in the shape of warmth has a tendency to grow the entropy of the system. The better the tropic stage, the greater the warmth to be had to growth entropy.What is an energy pyramid?
A strength pyramid additionally called atrophic or ecological pyramid is a graphical illustration of the strength located in the trophic degrees of an ecosystem. The backside and biggest stage of the pyramid is the manufacturers and includes the biggest quantity of strength.
Thus it is clear that energy is lost at each level as heat, which increases randomization.

The statements that describe the functions of the circulatory system are as follows:
Oxygen is delivered to cells throughout the body by this system.Nutrients are delivered to organs through this system.This system removes carbon dioxide from organs and delivers it to the lungs.This system plays a major role in fighting infections.What is the Circulatory system?The Circulatory system may be defined as a type of organ system that significantly involves the sequence of organs that togetherly work in order to circulate blood throughout the body. Examples of this organ system may include the heart, blood vessels, lymphatic vessels, and some glands.
According to the function of the circulatory system, it usually helps the body to fight against infections due to the role of white blood cells. The respiratory system significantly works along with the circulatory system in order to inhale atmospheric oxygen and exhale carbon dioxide through the lungs. But they are not the function of the circulatory system.

microwave. The TV commercials say that Popalicious is the fastest popping popcorn in the
world. Mr. Bailey's hypothesis was, "If I pop Jiffy Pop, Popalicious, and Pop-Tastic popcorn in a
microwave, then the Popalicious will pop faster because the commercial says so." He takes
Jiffy Pop, Popalicious, and Pop-Tastic and places them each in the microwave for 2 minutes.
After two minutes is up, he counts the number of POPPED kernels in the bag. After three trials,
Jiffy Pop had an average of 256 popped kernels, Popalicious had an average of 341 popped
