Which of the following is a TRUE statement about the differences between prokaryotic
and eukaryotic cells?
a. Eukaryotic cells contain a plasma membrane and cytoplasm, but prokaryotic cells
do not
b. Prokaryotic cells contain a nucleus and eukaryotic cells do not
C. Prokaryotic cells lack organelles, but eukaryotic cells possess organelles
d. All of the above are true
Answer:
B
Explanation:
The statement that gives the differences between prokaryotic and eukaryotic cells as regards this question is B: Prokaryotic cells contain a nucleus and eukaryotic cells do not.
Eukaryotic cells can be regarded as a cell that posses membrane-bound nucleus, while prokaryotic cell can be regarded as cells that doesn't posses a membrane-bound nucleus.Examples of organisms that can regarded as a eukaryotic are ; protists, fungi and plants, while that of prokaryotic cells are; bacteria and cyanobacteria archaea.Therefore, option B is correct.

The lab setup shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail.
In this setup, which tubes contain at least one organism carrying on cellular respiration?
A) Tubes 1 and 2 only.
B) Tubes 2 and 4 only.
C) Tubes 3 and 4 only.
D) Tubes 2, 3, and 4 only.
Answer:
I would assume D
Explanation:
Tube 1 doesn't contain an organism so it can't be that one. Both a snail and a plant are considered an organism, and cellular respiration occurs in almost any organism's cells

What type of solvent would dissolve a nonpolar solute
Answer:
Explanation:
For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
Answer:
Explanation:
Like dissolves in like, so only non-polar solutes can dissolve in non-polar solvents.

What would the density be of an object that has a mass of 50 g (grams) and a
volume of 10 ml (milliliters)?
Answer:
5
Explanation:
D=m/v
D=50/10
D=5
The density of an object that has a mass of 50 g and a volume of 10 ml would be:
Density = Mass / Volume
= 50 g / 10 ml
= 5 g/ml
What is density?Density is a measure of the mass of an object per unit of volume. It is a characteristic property of a substance and is often used to identify and classify materials. The density of an object can be affected by a variety of factors, including its composition, temperature, and pressure.
In general, denser materials tend to be heavier and more compact, while less dense materials tend to be lighter and less compact. For example, a substance with a high density, such as gold, will be much heavier than a substance with a low density, such as air.
Overall, the density of an object can be useful for understanding its physical properties and how it will behave in different situations.

.A substance from outside needs to reach genes in the cells of your body. In which order will it encounter different parts of the cell? cell wall -- cell membrane--- nuclear membrane ---cytoplasm—gene cell membrane--- cytoplasm –gene cell membrane--- cell wall ----cytoplasm---- nuclear membrane---- gene cell membrane -----cytoplasm----- nuclear membrane----- gene
Answer:
cell membrane -----cytoplasm----- nuclear membrane----- gene
Explanation:
A cell is made up of three part this include the cell membrane, the cytoplasm and the nucleus.
cell membrane encloses the cells and it prevent external material from getting inside the cell while the nucleus is formed by a nuclear membrane around a fluid nucleoplasm. chromatin in the nucleus contain deoxyribonucleic acid (DNA) which is the genetic material of the cell.
The cytoplasm is fluid found in the cell. It is gel like in nature and a medium for chemical reaction.
cell membrane -----cytoplasm----- nuclear membrane----- gene
The arrangement will be a cell membrane for protection followed by the cytoplasm thatbis located in between the cell membrane and the nucleus then the nuclear member found around the nucleus. The nucleus contains the DNA which is the genetic information of an individual gene.
