You have an egg that has an internal 7% salt concentration and you put it into a bowl of 3% salt water. What is the tonicity of

the egg? What is the tonicity of the water in the bowl? Explain what will happen to the egg over time. Assume water can move across the cell membrane but the salt cannot. Be sure to use the appropriate terms to describe what occurs (solvent, solute, tonicity, specific type of transport, etc.) (2-3 sentences) *50 points

Answer:

Egg is HYPERTONIC

Water in the bowl is HYPOTONIC

The egg will become filled with water over time

Explanation:

Tonicity refers to the ability of an extracellular solution to direct the flow of a solvent (water) in and out a cell. There are three types of tonicity; hypertonic, hypotonic and isotonic. A solution is said to be HYPERTONIC when the concentration of solute in it is higher than its external solution. This is the case of the egg cell that contains 7% salt (solute).

A HYPOTONIC solution is that which contains a lower solute concentration than it's external solution. This is the case of the water in the bowl that contains 3% salt concentration.

Tonicity determines which direction osmosis occurs. Osmosis is the movement of solvent/water from a region of high solvent concentration/low solute to a region of low solvent concentration/high solute concentration via a semi-permeable membrane. In this case, water (solvent) will move through the egg cell membrane (semi-permeable membrane) from the bowl with a low solute concentration into the egg with a high solute concentration. Hence, over time, the egg cell will be filled with water.

Which is true of genes found on chromosomes?
PSYCHO15rus [73]
The option that is true of genes found on chromosomes is that D. they determine the inherited traits of an organism.
Genes are inherited - so those are the things that we get from our parents and other ancestors. It is easy to determine which of these genes a child is going to inherit - the doctors just need to take a look at the chromosomes, because genes are located there.

When you eat a meal, food is digested and monomers like glucose are transported throughout your body. food is transformed and us
Alchen [17]
<span>Food molecules like lipids, proteins and polysaccharides are broken down enzymatically via digestion process, which occurs in our intestine cells (digestive system). Those large polymeric molecules are broken down into their monomer subunits—proteins into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol. Formed small organic molecules are now ready for the oxidation (a process that produces ATP and consumes O2) which occurs partly in the cytosol and in the mitochondrion. Oxidation processes include glycolysis and citric acid cycle which are differently required in different tissues. Nervous system (nerve cells) rely almost entirely on a constant supply of <span>glucose<span> from the bloodstream. In contrast, liver cells supply glucose to actively contracting muscle system which needs a lot of ATP energy.</span></span></span>

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

How are luminosity and magnitude related?<br>(In your own words) ​
statuscvo [17]

Answer:

Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.

Round pea allele R is dominant to wrinkled pea allele r, while yellow pea allele Y is dominant to green pea allele y. Homozygous
allsm [11]

Answer:

RrYy (F1 generation)

Explanation:

This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.

According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.

Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.

In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.

Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
