45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?

Answers

Answer:

Explanation:

Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.

The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.

The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.

Chloroplasts and Mitochondria are two organelles that are largely
responsible for the cycling of carbon through the ecosystems. What are
their functions?

Answers

Function for Mitochondria - Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Function for Chloroplast - In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

during glycolysis?
a) Nothing, glycolysis does not affect the glucose molecule
b) The atoms are converted into other molecules in a series of chemical reactions
c) The atoms are transformed into energy
d) All atoms are transformed into other atoms in a series of chemical reactions

Answers

Answer:

b.

Explanation:

the atoms are converted into other molecules (pyruvate) in a series of chemical reactions

Glucose consists of carbon, oxygen and hydrogen atoms. The thing that happens to these atoms  during glycolysi is that The atoms are transformed into energy

Glucose is a type of simple sugar that has six carbon atoms and during glycolysis, is broken down easily because it is a monosaccharide

Glycolysis is the process of breaking down and converting glucose into CH₃COCOOH.

Therefore, what happens to carbon, oxygen and hydrogen atoms during glycolysis is that they are transformed to energy

define magnification and cisternae?​

Answers

Answer:

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.

Explanation:

It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove

Answers

Answer:

Small intestine

Explanation:

Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.

However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.

Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?
A.
In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B.
In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.
C.
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
D.
In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.

Answers

Answer:

B. Cycle

Explanation:

Lichen performs photosynthesis with the assistance of an algal partner, but Elysia chlorotica incorporates the chloroplast from an algal partner, which is how lichens vary from Elysia chlorotica in this regard,  hence option C is correct.

How does lichen photosynthesize?

A process known as photosynthesis is one in which green plants and some photosynthetic algae produce their own food, glucose, using carbon dioxide and water in the presence of light.

Lichen is a symbiotic association between an algal component that produces food and a dominant partner fungus that gives the lichen its thallus form and fruiting bodies. A particular species of mollusc called Elysia chlorotica uses the chloroplast of an algal partner to carry out the photosynthesis process.

Therefore, Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells, hence option C is correct.
