1. Would you consider a Zonkey (baby created from a donkey raised with a zebra) alive? Keep in mind that a Zonkey is sterile and cannot produce its own offspring.
2. Would you consider a virus alive? It requires a host completely to live.
Answer to 1:Yes the Zonkey is alive,not all organisms can reproduce. Some people are born with rare genetics were they can't give birth,so even if the Zonkey is sterile and can't produces it own offspring it is alive.
Answer to 2:Yes a virus is alive,it attacks the host and contains/kill other cells in your body. They also can multiple. If they can multiply and even attack and kill other cells they are alive.
I couldn’t fit the whole question in so the last two options are
-Natural disasters are so rare that they have not affected human population very much
-Natural disasters are a concern for human, life and property, but there is nothing we can do to predict them or prepare for them

what is unequal sharing of electrons
Answer:
Covalent bond between two atoms with unequal electronegativities results in unequal sharing of electrons. These types of covalent bonds are called polar bonds because the electron distribution or charge is unevenly distributed or polarized. .

Answer:
Comparison microscope
Explanation:
The correct answer would be the comparison microscope.
The comparison microscope consists of two compound microscopes with a center eyepiece. The eyepiece captures and displays the images from the two microscopes and the observer can compare and contrast for investigative purposes.
The capacity to produce two images for comparison purposes makes the microscope useful in forensic investigations.

Answer: In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

how do photosynthesis and cellular respiration affect the CO2 and O2 in our atmosphere?
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
During the photosynthetic process, glucose and what other molecule are created
durring puberty
Explanation:
Answer:
Oxygen
Explanation:
"Photosynthesis" is a process that is being used by plants in order to sustain their metabolic needs. In order to do this, it converts "light energy" into "chemical energy." There are mainly three things that are needed for the process: sunlight, water and carbon dioxide.
Sunlight (provides light energy) comes from the sun while water is drawn from the plant's roots. The light energy fuels the process. Carbon dioxide, on the other hand, is taken from the air by the plant's leaves. Once these three things are combined, they produce sugar ([tex]C_{6} H_{12} O_{6}[/tex]) and oxygen (6[tex]O_{2}[/tex]). So, the other molecule being asked above is "Oxygen."
Describe the effects of estrogen on

Answer: it’s C
Explanation:
if we place a dialysis tube filled with water that is a 10% salt solution into a beaker that has a 5% salt solution water will...
A. have net movement OUT of the tube, this is a hypertonic solution compared to inside the tube
B. have net movement into the tube, this is a hypotonic solution compared to inside the tube
C. have net movement OUT of the tube, this is a hypotonic solution compared to inside the tube
D. have no net movement, this is an isotonic solution compared to inside the tube.
Answer:
The correct option is D.
have no net movement, this is an isotonic solution compared to inside the tube.
Explanation:
It will have no net movement, this is an isotonic solution compared to inside the tube because isotonic solution is a solution that has the same osmolarity or solute concentration in both solution, which allow free water movement across the semi permeable memberane on both solution i.e the concentration of the two solution are mostly the same.
