Osmosis is the net movement of water across a semi-permeable membrane from an area of lower gradient concentration to an area of higher gradient concentration. On the other hand, tonicity is the ability of an extracellular fluid to make water move into or out of a cell through osmosis. A solution's tonicity is related to its osmolarity or the total concentration of the solutes in a solution.

When solutions of varying osmolarities are separated through a membrane that is permeable to water but not to solute, water from the side with lower osmolarity will move to the area with higher osmolarity.

<span>Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse. Therefore, these solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure (due to the inflow of water to the blood stream by osmosis) may cause high blood volumes being pumped by the heart hence high blood pressure</span>

Write a claim about whether you will consume or not cinsume lactose
Vsevolod [243]

Answer:

See explanation below:

Explanation:

Lactose is found in milk. It is part of the reason milk tastes somewhat sweet since Lactose is a sugar. Anyone that consumes milk or anything with milk in it, will consume Lactose.

As for me, I plan on having some Ice-Cream later. Since there is milk in Ice-Cream, I will consume Lactose today.

Hope this helps! Have an Awesome Day!!

Which is an example of the use of plants in human society? Fossil fuel usage causes the elimination of carbon sinks. Plants make
padilas [110]

I believe the answer is plants make flowers to attract insects because, plants do nit store carbohydrates, meat does, and we cant use plants to create fossil fuel. The only plant fibers we use for clothing is cotton so that is very limited in the wide aspect of things.

icang [17]
1. breeding of individuals that have genes for two different characteristics:
DIHYBRID CROSS.
We call it a dihybrid cross when we are considering a cross between two different traits.
"di" means having two traits involved (for example, trait A and trait B), the "hybrid" means that each trait will have two different alleles (for gene A: A or a; for gene B: B or b), one is dominant and the other is recessive.

2. a grid system used to predict possible combinations of genes due to random fertilization: PUNNETT SQUARE
The Punnett square is a grid system that helps us predict an outcome of a cross or a breeding experiment. We this, we can determine the probability of an offspring having a particular genotype.
This is very useful when we are considering more than one gene,  making it less confusing.

3. a condition in which both alleles are dominant: CODOMINANCE
Tere are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB):  100% of the offspring being WB. With this genotype, they have black feathers and white feathers. It's not a blend of colors, but a case where both are expressing.

4. when more than two alternatives exist for a gene: MULTIPLE ALLELES
Mendel thought that only two possible alternatives could exist for a gene, but there are cases that have more than 3 possibilities. Some of those can be really popular in a population while others not so much.
This happens with rabbit's fur. They can be black, brown, grayish,
Himalayan patterning or white fur.

 5.a condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype: INCOMPLETE DOMINANCE
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr-white
By crossing this plants we will obtain 100%  of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.

The  best  way for  the nurse  to  help alleviate the  back  pain  to a woman  whose  fetus in  the  occiput posterior  position  which  is  experiencing  increase  pain  is  to apply  counter  pressure to  the back. These  counter  pressure  help  the  woman  to  cope back  labor associated  with  occiput posterior  position
