How do you define osmos ?

Biology
1 answer:
Arlecino [84]3 years ago
5 0
I think you're looking for osmosis.

Osmosis is a kind of method where substances used to flow from a place to another. Osmosis is where water molecules flow from a region of higher water potential to a region of lower water potential, through a partially permeable membrane.

A partially permeable membrane means that membrane can select what can go through or not. Also, osmosis must be the flow of water, nothing else.

How do bacteria enable a baby to extract nutrition from the mother's milk?
Firlakuza [10]

Answer:

Lots of bacteria are present as the microflora of a baby's gut which helps it to extract the nutrition from mother's milk and also helps the baby to maintain a low number of pathogenic bacteria in its gut.

Some bacteria present in the baby gut release enzymes like glycoside hydrolase which helps baby to digest carbohydrate present in the mother's milk.  

Bacteria like Bifidobacterium, Streptococcus, Staphylococcus are already present in breast milk which helps in making gut microflora of baby and this gut microflora helps in extracting nutrients from mother's milk.

If you know that a population is 75% the dominant phenotype and 25% is the recessive phenotype, can you determine approximately
Andreyy89
If dominant allele = p, and recessive allele = q,
and p+q = 1, then:
{(p + q)}^{2}  =  {p}^{2}  + 2pq +  {q}^{2}  \\ where \:  {p}^{2}  \: is \: homozygous \: domin \\  {q}^{2}  \: is \: homozygous \: recessive \\ and \: 2pq = heterozygous
So if 75% have the p, then p^2 = homozygous dominant
{p}^{2}  =  {(.75)}^{2}  = .5625
And if the other 25% have the q, the q^2 = homozygous recessive
{q}^{2}  =  {(.25)}^{2}  = .0625
Now those remaining MUST be the heterozygous, thus 2pq are those:
2pq = 2(.75)(.25) = .375

Therefore homozygous dominant are 56.3% and heterozygous are 37.5%

True or false: single sugars are too large to be absorbed directly into the bloodstream
AleksandrR [38]

Answer:

False

Explanation:

The sugars on the basis of the number of glucose or sugar units can be categorized into two categories:

1. Simple sugars: The sugars which contain one or two sugar units called mono and disaccharides.

2. Complex sugars: The sugars which contain more than two sugar units are complex sugars.

The simple sugars like glucose, galactose are easily digested by the digestive system of the human body and easily absorbed by the cells.

Since the simple sugars or simple sugars are small in their structure compared to the complex carbohydrates therefore false is the correct answer.
