PLEASE HELP ME I'LL MAKE YOU BRAINLIEST!!!!!!!!!! Lichens can best be described by which of the following? a) autotrophic organisms and fungi in a mutualistic relationship b) photosynthesizing fungi that can live in harsh environment conditions c) saprophytic fungi that secretes acids to grow on and colonize rocks d) two heterotrophic fungi species that thrive on nutrients from the air
Answer:
a) autotrophic organisms and fungi in a mutualistic relationship
Explanation:
A lichen "is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species".
It is cyanobacteria + fungi, so it has to be two separate groups, and both cannot be fungi.
Your question has been heard loud and clear.
answer is option C , lichens do colonize on rocks most of the time , this is because they really are saprophytic fungi , that secrete acids to melt and make the rocks suitable for growing on.

In brief state what happens when a) dry apricots are left transferred to sugar solution? b) a Red Blood Cell is kept in concentrated saline solution? c) the Plasma-membrane of a cell breaks down? d) rheo leaves are boiled in water first and then a drop of sugar syrup is put on it? e) golgi apparatus is removed from the cell?
Answer:
Explanation:
(a) Dry apricots when placed in pure water swell due to osmosis and when in sugar water, they shrink again.
(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.
(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.
(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane.
(e) Golgi complex helps in the package, storage and transfer of proteins synthesized by ribosomes. Thus, when ribosomes are removed the cell will not function properly
At label ________, the cell is not hyperpolarized; however, repolarization is in progress, as the sodium channels are inactivated or becoming inactivated, and many potassium channels have opened.
Answer: C
Explanation:
When a neuron receives a stimulus, the sodium channels present in the membrane are opened, and therefore Na+ enters the cell in favour of the concentration gradient, so that the membrane potential changes to positive by means of ion exchange, producing depolarization. If this depolarization reaches a certain threshold value, an action potential is generated. The next step is the opening of the potassium channels and the inactivation of the sodium channels, so that the repolarization of the membrane takes place. The sodium channels, will return to the closed state in the hyperpolarization to continue in this state during all the rest potential achieving the action potential to return to -70 mV (repolarization).; until the arrival of a new action potential which produces the activation and opening of the sodium channels, repeating the cycle again and generating a new depolarizing action. This process is part of the synaptic transmission.
So, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. This means, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in membrane voltage where the membrane potential is more distinctly positive or negative are hyperpolarizations.
During the repolarization period after an action potential, the membrane potential is more negative than when the cell is in "rest period". In the picture, this repolarization period is about 1-2 milliseconds. So, repolarization is the time in which the membrane potential is hyperpolarized with respect to the resting potential.
In the attached figure, part C indicates this repolarization period.

The Peppered moth is white with black spots, which helps it blend in with the bark on beech trees. The burning of coal in Great Britain caused many beech trees to become black with soot. Over time, the Peppered moth became all black in order to blend in with the new bark color. What type of example is this? homeostasis metabolism organization adaptation
Answer:
adaptation
Explanation:
Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.
In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.
Therefore, this is an example of ADAPTATION.

Which axiom is used to prove that the product of two rational numbers is rational?(1 point) Integers are closed under multiplication. Integers are closed under division. Whole numbers are closed under division. Natural numbers are closed under multiplication.
Answer: Integers are closed under multiplication.
Explanation:
Rational numbers are numbers of the form:
a/b
such that a and b are integers.
The axiom: " Integers are closed under multiplication. "
Says that if we have two integers, x and y, then:
x*y is also an integer.
So if we have two rational numbers,
a/b and c/d
Such that a, b, c and d are integers, and we multiply them, we have:
(a/b)*(c/d) = (a*c/b*d)
the numerator is a*c is the product of two integers, so this is an integer by the previous axiom.
the denominator is b*d, also a product of integers, so this is an integer.
then (a*d)/(b*d) is the quotient of two integers, then this is a rational number.
Answer:
the second one... Integers are closed under multiplication

What are the three basic parts of the cell theory?
Answer:
Answer
Explanation:
All living things are composed of cells.
Cells are the basic units of structure and function for living things.
All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.
The three basic parts of the cell theory are:
All living things are made of cells.
Cells come from preexisting cells.
All cells have the same basic parts.
How do we explain?Cells are the basic unit of life. All living things, from the smallest bacteria to the largest redwood tree, are made up of cells.
Cells are not created spontaneously. All cells come from the division of preexisting cells.
Despite their great diversity, all cells have the same basic parts, including a plasma membrane, cytoplasm, and DNA.
The cell theory was first proposed by Matthias Schleiden and Theodor Schwann in the 1830s. It has since been supported by a vast body of evidence from cell biology. The cell theory is one of the most important and fundamental concepts in biology.

Dump out half of the particles. Place your hand tightly over the top and shake the container. Then remove most of the remaining particles, and shake the container again. Compared with the full container, which states of matter do these two models most closely represent? Explain.
Answer:
solid
Explanation:
The two models explained are most closely representing the "solid" state.
As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.
Hence, the correct answer is "Solid".
Answer:
When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.
