Answer:
A. Haploid (n)
Explanation:
Conifers do not exhibit double fertilization that forms triploid (3n) endosperm in flowering plants.
Endosperm in conifers develops from the haploid cell of female gametophyte before fertilization. Since the endosperm is formed by the mitotic divisions in the haploid cell (n) of female gametophyte, it is haploid (n) in nature.
A
Because grass is a plant so it’s like living compared to water and being active isn’t even a part of the environment
Answer:
Reactants: hydrogen and oxygen
Products: water
Explanation:
The reactants are what goes into a reaction, i.e. what is reacting. The products are what is formed. The reactants are usually shown on the left, and the products are usually shown on the right.
We can see in this equation that hydrogen (2H2) is reacting with oxygen (O2) to form water (2H2O). Therefore the reactants are hydrogen and oxygen, and the product is water.
<u>Answer:</u>
<em>In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously</em>.
<u>Explanation:</u>
Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. <em>The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.</em>
This clock does not measure any time but the number of mutations, and other changes over certain time. <em>Sometimes its useful property might be limited due to the highly diverged lineages.</em>
Answer:
31. Seatbelts lock in place to make sure you don't go flying into the windshield.
32. Friction causes the soccer ball to slow down. If we were to kick a soccer ball in space, where there is no friction, it would keep on rolling until it eventually hits something or goes out of sight.
33. Heavier loads will make the vehicle move off of the table. The heavier the weight, the quicker the vehicle will roll. Loads that are something very similar or lighter than the vehicle won't make the vehicle move by any means.
34. Gravity is the power pulling the piano toward the Earth.
Friction would happen with an unpleasant surface, making it a lot harder to push the piano up the ramp.
35. Wagon C
Wagon C has the least boxes and minimal measure of mass, making it simplest to move.
36. I would move the crates so every cart has a similar measure of boxes, making them equivalent in mass. This would make them all take a similar measure of power to move them.
Explanation: I have the answer key
