How do tree grow??
Answer:
Tree branches/trunks grow as new cells are produced under the bark. Trees grow taller when new cells are produced at the tips of twigs, causing the twigs to grow longer. There are cells in the tree that carry water & food throughout the tree.

Why does cell size need to be limited?
Where does the DNA come from that is in the parent cell?
Answer:
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.
The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

Why is it important to have a control group in the experimental design?
The control group is the main one because it acts as a benchmark to balance the results of the experiment.
What is control group in the experiment?Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.
So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.

what are the different parts of microscope ?A microscope is which produces large images of tiny substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.
Anatomically the microscope consist of three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.
Base of microscope is used to support and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.
The optical parts are basically applied for the view, magnify, and production of an image from a specimen placed and the various parts.
Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

A nerve impulse is an electrical charge running across a neuron. Explain why the simulation supports this explanation.
Answer:
Sudden reversal of the electrical charge across the membrane of resting neuron
Answer:
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

Explain how 1st and 2nd law of thermodynamics applies to the trophic structure of an ecosystem?
Answer:
First law: In the ecosystem, the energy flow from lower levels of the food chain to the highest levels
Second law: During energy transference between trophic levels, the main part of the energy is lost as heat and other processes.
Explanation:
The first law of thermodynamics states that the energy can not be created or destroyed, but instead it is transformed into one type to another. Moreover, the second law states that when energy is transformed an important proportion of this energy is lost as heat, and it increases the entropy level.
In an ecosystem, the energy flow is unidirectional, it means that energy flow from primary producers to primary consumers, then from primary consumers to secondary consumers and so successively in all levels. Moreover, organisms fight against entropy by converting foods into energy (which is used to maintain order within their cells. During the feeding process, the energy intake is not 100 % efficient, it means that most part of the energy is lost as heat (approximately 90%), thereby increasing the entropy in the ecosystem.

if one species in a community dies out or moves, the community will
Answer:
The community will slowly decline, or be just fine, or be better off.
Explanation:
Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.
If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).
And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

When the concentration of molecules on both sides of a membrane is the SAME, the solution is
Answer:
When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.
Explanation:
A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.
The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.
An isotonic solution does not generate gradients, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.
