The part whose main job is to direct a plant cell's activities by sending instructions to different parts of the cell is the nucleus. It directs the cell's activities in the plant and animal cells.
What is the short definition of a plant cell?Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals. Nucleus part main job is to direct a plant cell's activities by sending instructions to different parts of the cell.
Therefore, The part whose main job is to direct a plant cell's activities by sending instructions to different parts of the cell is the nucleus. It directs the cell's activities in the plant and animal cells.

There are 22 different amino acids. What part of each amino acid is differnt from the others
Answer:
Amino acids are units or building blocks of protein. These are crystalline solid without any colour and are soluble in water and insoluble in the organic solvent. All amino acids have five basic parts. These are a central carbon (C) atom, hydrogen(H) atom, an amino group (NH2) with one nitrogen atom and two hydrogen atoms, a carboxyl group (COOH) having one carbon atom, two oxygen atoms, and one hydrogen atom and an R-group or side chain. There are 22 different types of amino acids. They are different due to the different side chain or R-group. For example, if the side chain is H, the amino acid is Glycine and if side chain is CH3, the amino acid is Alanine

Explanation:
The cell cycle requires energy. Which process supplies this energy so that the cell cycle can take place in all living things
Answer:
Cellular respiration
Explanation:
All living cells strictly require energy in form of ATP to perform their cellular functions. This energy is obtained when food molecules are broken down on their cells in order to release the stored energy in their bonds. This anabolic process is called CELLULAR RESPIRATION.
CELL CYCLE is one of the cellular functions performed by a cell, as every cell needs to undergo division. According to this question, the cell cycle requires energy, which is also supplied via the process of CELLULAR RESPIRATION.

Explanation:
How many teaspoons of sugar can dissolve in hot water until it will no longer dissolve after stirring
Answer:
it depends on what sugar you are using
Explanation:
Answer:
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster
Choose THREE reasons why less energy is passed from one trophic level
to the next
А
Energy is stored within organisms.
B
Energy is stored in the decomposers.
С
Energy is lost as heat to the environment.
D
Tertiary consumers use up all of the energy.
m
All of the energy is used by the primary consumers.
F
Energy is used by organisms to perform life functions.
Answer:
A, C, and F
Explanation:
Each of these answers show a way that energy is used which is why there is less energy in the next trophic level than the first
Less energy is passed from one tropical level to another because energy is lost as heat to the environment. So the correct option is C.
What is the ten percent law?The pyramid of energy describes how energy moves from one trophic level to the next in a food chain. The 10% law states that 90% of the energy that is gathered is wasted as heat in the original level and just 10% is left for the following level.
About 10% of the energy is used for metabolic processes at each trophic level, with the remaining energy being lost as heat to the environment. At each level, the chemical energy decreases but the overall system energy does not.
According to the 10% law, only 10% of energy is moved from a lower to a higher trophic level. Accordingly, only 10% of the energy that producers have conserved gets transmitted to herbivores.
Plants use the remaining 90% of this energy for a variety of functions, including breathing, growth, and reproduction.
The energy transmitted from herbivores to carnivores is also just 10% of the total. Therefore the correct option is C.

Water potential is the tendency of water to move from one place to another. Pumpkin cores were placed in sucrose solutions at 22°C and normal atmospheric pressure. The following data were gathered.
Individual Data for Pumpkin Cores

change in mass
Water 29.15 32.12
0.2 M sucrose 28.45 29.41
0.4 M sucrose 30.92 29.84
0.6 M sucrose 29.25 27.14
0.8 M sucrose 32.09 28.54
1.0 M sucrose 31.67 27.58
a) Complete the above table
b) Graph the percentage change in mass. Label both the x and y axes.
c) Using the graph, determine the molar concentration of the pumpkin cores and explain how it is related to pressure potential.
Answer:
For part A this is how you solve it:
Final mass-Initial mass=x. Then divide x/initial mass to get final percentage
32.12-29.15=2.97. 2.97/29.15= 10.19%
29.41-28.45=0.96. 0.96/28.46= 3.37%
