Explanation:
In living things, cells must be in a _____________________ solution where water leaves and enters the cell at _________________________________________.
Answer:
isotonic; the same rate
Explanation:
Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.
For cell that is in an isotonic solution,no net flow of water into or out of the cell will be experienced, the volume of the cell is at a state of stability. When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.

What can be considered as an extreme disturbance to any ecosystem is :extreme temperature change.
Whenever, there is a disturbance in terms of fire or toxic chemicals to ecosystem, then : living things in that ecosystem.
In a case, whereby no one hunt deer, then there would be decrease in smaller herbivore population.
loss of a river system due to contamination can be considered as a of a severe disruption to an ecosystem.
When there is irreversibility destroying of ecosystem, then :species unable to travel or adapt will die out in the area.

ii Why can you not produce plumcot seeds through reproduction between two plumcot plants?
Answer:
It's a great tree for small properties because you only need one to produce fruit. Pluots are similar fruits. ... The seeds from the cross-pollinated fruit produce a different type of tree that has some characteristics of both trees.
Explanation:
sorry
A plumcot plant is produced from the cross breeding between a plum and an apricot tree. It is hybrid fruit tree.
As the plants is a hybrid fruit tree, it is not possible to produce plumcot plants through fertilization of their seeds.
A plumcot plant is derived from the reproduction between a plum and an apricot. It takes skill and planning to be able to carry out the cross pollination. Most of the time this occurs when they are found growing near each other.

Earth follows an orbit as it makes a revolution around the Sun. What is the relationship between a revolution and an orbit?
Answer:
An orbit is essentially the motion of an object (be it a planet, a moon, a spacecraft) around a star, moon, or planet. Now a revolution is the movement of an object around an axis of rotation, or a centre, or another object. So the earth revolves around the sun, but the earth is also in orbit around the sun.

If a cell has 40% solute and is placed in a solution with 60% water what will happen to the cell
There will be no net movement of water in or out of the cell.
Water moves out of the cell when a cell is placed in a hypertonic solution. This is a solution that contains more solute than does the cell. When a cell is placed in a hypotonic solution, water enters into the cell from the solution until the cell finally bursts. However, if the cell and the solution contain the same amount of solute, there is no net movement in or out of the cell.
We can see here that the cell has 40% solute and is placed inside a solution that has 60% water. This means that the solution also contains 40% solute. There will be no net movement of water in or out of the cell.

Which marble will experience the least acceleration?
O Marble A
O Marble B
Marble C
Marble D
Answer:
Marble D
Explanation:
According to this question, a group of four students is participating in a marble race. Each marble is said to have different mass but the same force were applied to each of them.
The relationship between the mass, force and acceleration of an object has been explained with the equation: F (force) = mass (m) × acceleration (a).
F = ma
Hence, a = F/m
Based on this, with a constant force, the acceleration is inversely proportional to the mass of an object. This means that when the mass increases, the acceleration decreases and vice versa. Based on the table showing the value for mass and uniform force for each marble, the marble with the highest mass (90) will have the least acceleration (0.66666). This marble is MARBLE D.
Which small-scale mutation would be most likely to have the least negative effect on the function of a protein?
A substitution of one base for another within the sequence
A base deletion near the start of a gene
A base deletion near the end of the coding sequence, but not in the terminator codon
A deletion of three bases near the start of the coding sequence, but not in the initiator codon
Answer:
substitution
Explanation:
has a chance to cause silent mutation, which doesnt do anything to a protein.
The small-scale mutation that would most likely have the least negative effect on the function of a protein is ; ( A ) A substitution of one base for another within the sequence.
A substitution of one base for another within the sequence of a protein will cause an insignificant/silent mutation within the protein sequence and this mutation will not be evident in the protein.
When a base is deleted either near the start of a gene or near the end of the coding sequence, it will have a significant effect because this will change the sequence of the DNA ( due to the deletion of at least one nucleotide ).
Hence we can conclude that the small-scale mutation that would most likely have the least negative effect on the function of a protein is ; A substitution of one base for another within the sequence.
