If the percent concentration is greater in the fluid outside a cell than inside a cell, how will the water
flow?
This means the solution would be___________
Which tube(s) did this happen to?
Answer:
The water will flow from the inside of the cell to the fluid outside the cell. This means that the solution would be hypertonic.
It will happen to the tubes that have a higher concentration of solutes in the fluid outside cells than inside the cells.
Explanation:
When a cell is in a hypotonic solution, it means that the concentration of solute in the solution is higher than the one in the cell. As a natural reaction, the cell tries to balance this difference. To do this, the water that is inside the cell flows to the outside. As a result, the concentration between the inside and the outside of the cell becomes equal or more equitable. Besides, the cell shrinks due to the loss of water.

how do i explain assimilation of glucose, amino acid and lipid?
Assimilation simply means the ways by which some of the food we eat and are absorbed by the body are being converted to new protoplasm or used to provide new energy for the body.
ASSIMILATION OF GLUCOSE
The hepatic portal vein transports absorbed sugars to the liver,the excess glucose is then converted to glycogen by insulin.When needed by the body,the liver in-turn converts this glycogen to glucose so that they can be moved to the cells,from there glucose is transported to every other parts of the body so that they can provide the cells with needed energy,during cell respiration,glucose is oxidized to release energy to be used for vital activities.
ASSIMILATION OF AMINO ACIDS.
Amino acids which are end products of protein passes through the liver to all parts of the body.
When amino acids are excess in the body,they will be deaminated in the liver to form urea, amino acids aren't stored,they are used to make proteins,repair worn out cells, aids growth, formation of enzymes and hormones and conversion into new protoplasm.
ASSIMILATION OF LIPIDS
Lipids which are end products of fats and oils are transported by the lymphatic capillaries or lacteal.
When lymph comes together with fat, chyle is formed,this chyle will further be discharged into the bloodstream and will be carried by the blood.
Fats are used to alternate source of energy for the body and as well form new protoplasm like the cell membrane.
When fats are in excess,they are stored in the adipose tissue which are found around the heart, kidneys, beneath the skin,and mesenteries that binds the intestines.

Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible? (1 point)
O Metals have low electronegativity, so they are conductive because they pass charges easily.
OTwo metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
O The bonds can shift because valence electrons are held loosely and move freely.
O An attraction between a positive charge and a negative charge is created.
The correct answer is; Metals have low electronegativity, so they are conductive because they pass charges easily.
Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.
A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.
This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.

Keloids occur when skin around wounds continues to grow after the skin has healed. A disruption in the regulation of which cellular process is probably responsible for this condition
Options
A. Mitosis
B. Meiosis
C. Apoptosis
D. Phagocytosis
Answer:
A
Explanation:
Mitosis is a type of cell division which takes place in living organism during growth and development.Therefore it is ensures the regenerations of cells and tissues during healing.
Therefore the restoration of new cells to the skin following injuries is due to mitosis.Since this is a multiplication division(2n) in which the daughter cells are exactly like the parents' cells the new tissues of the skin by mitosis, look exactly like the previous one that was injured.
In cases where the mitotic growth control is lost, the scare tissues of the injured part overgrows with granulation tissues and this leads to Kaloids.
Its is a mass of Collagen Type 1.(Collagen is an fibrous proteins which has largest proportion in mammals).
Keloids is characterized with pink or red coloration and elevation of the area,excessive growth of the area, with irritating patch skin

Water intoxication results from: A. Dilute body fluids B. Osmosis of water from ICF to ECF C. Decrease in water intake D. Decrease in the osmolarity of interstitial fluids E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids
Answer:
E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids
Explanation:
When there is excessive water intake into the body, it can lead to water intoxication. It occurs as result of a combination of dilute body fluids and decrease in the osmolarity of interstitial fluids.
When excess water is taken into the body, the extracellular fliuds become very dilute, this results in a decrease in osmolarity , therefore, water will then move into the intracellular fluid by osmosis in order to establish equilibrium.. This causes the cells to swell, and in the brain, this swelling will result in increase in pressure within the cranium. This increase in pressure leads to the symptoms found in water intoxication such as nausea, confusion, and fainting. If not treated, it can result in death.
From the given options;
A. Dilute body fluids is only a part of the cause
B. Osmosis of water from ICF to ECF does not result in water intoxication because in water intoxication, water moves into the ICF from ECF
C. Decrease in water intake is wrong because it is an increase in water intake that results in water intoxication
D. Decrease in the osmolarity of interstitial fluids is only one part of the cause of water intoxication
E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids is the correct option.

What is the friction force of an object wtih a gravity force of 30N, normal force of 30N, applied force of 6N to the right, and a net force of 20N to the left?
Explanation:
Given that,
The force of gravity is 30 N
Normal force is 30 N
Applied force is 6 N (right)
Net force is 20 N (left)
We need to find the friction force of the object. We know that friction is an opposing force. It always acts in the opposite direction of the applied force. The magnitude of applied force and friction force is same but direction is different.
Hence, frictional force is 6 N to the left.
Some birds on the Galapagos Islands build nests in trees, while others hide eggs in rock crevices. What could account for this difference in nesting behaviors?
Answer:
Food habits, predators.
Explanation:
The biggest reasons are food habits and predators, most birds who nest on the ground either can't fly or use this to be closer to their food. A ground bird (Like quail) can fly but choose to be more ground-based birds.
Most of the time it's because these birds forage for food like ground insects, seeds from the brush that grows on the ground, or fallen fruit.
Most birds that live in the trees feast on seeds, leaves, or insects found close to where they choose to nest. They may also want to escape any predators that may be towards the ground.

Answer:
C
Explanation:
According to the endosymbiotic idea, a few eukaryotic cells' organelles were previously prokaryotic microorganisms. Chloroplasts and mitochondria divide by binary fission. Therefore, option (C) is correct.
What is Endosymbiotic Theory ?According to the endosymbiotic theory, eukaryote cell organelles like chloroplasts and mitochondria descended from separate bacteria that eventually developed symbiotic relationships with other cells.
Both mitochondria and chloroplasts have circular, single-stranded DNA in addition to not having histones. Prokaryotes are the only organisms that have single-stranded, circular DNA. They contain their own ribosomes to translate and make proteins. These qualities would enable the mitochondria and chloroplasts to thrive on their own, supporting the endosymbiosis theory.
Therefore, option (C) supports the theory of the endosymbiotic origin of chloroplasts.
