Answer:
2. C
3. D
Explanation:
2. Ionic bonds are chemical bonds that forms between the ions of molecules or compounds. The two molecules are joined together by an electrostatic force. This is the case of the bond that forms between the slight negative charge (anion) at one end of a water molecule and the slight positive charge (cation) of a second water molecule.
3. Cohesion refers to the attraction of a molecule to a like molecule. The cohesiveness of water molecule to another water molecule is great due to the HYDROGEN BONDS that forms between them.
10. Which structures are involved in cell movement?
Answer:
Cilia and flagella are the two structures cells use of their movement and locomotion.
Cilia and flagella are projections from the cell. They are made up of microtubules.
They are motile and designed either to move the cell itself or to move substances over or around the cell.

Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly describe the cellular effect that occurs in the presence of epinephrine.
Answer:
I haven't really learned about cell types but I did find this information
Explanation:
How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.
epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

The population in a 50 square mile area is 200 people. What is the population density?
Answer:
[tex]\rho _{population}=4\frac{people}{mi^2}[/tex]
Explanation:
Hello.
In this case, since the population density is computed by dividing the amount of people by the space (area) where they are in:
[tex]\rho _{population}=\frac{people}{area}[/tex]
For 200 people living in a 50-mi² area, the population density is:
[tex]\rho _{population}=\frac{200people}{50mi^2}\\\\\rho _{population}=4\frac{people}{mi^2}[/tex]
It means that 4 people live per square mile area.
Best regards.
How does the experience of seeing a green leaf, connect with nuclear fusion in the Sun.
Answer:
The Sun shines because it is able to convert energy from gravity into light. This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion. Hope this helps

How the coin flip relates to the probability of inheriting genetic condition?
Answer:
A coin represents a diploid, heterozygous cell with its heads and tails sides. The act of tossing the coin to land on heads or tails, provides an apt representation of the segregation of alleles during meiosis in the formation of gametes.
or i guess you could just say its all by chance ;P
peace :)
Answer:
It is very similar to the way traits are inherited in nature, as both combinations occur by chance. Though, in the coin toss, there are only 2 possible alleles whereas in nature there may be more complicated combinations of alleles for traits.
Explanation:
Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
