Answer:

Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.

Explanation:

Trypsin and chymotrypsin are known as proteolytic enzymes which are actively involved in the digestive system. They are both secreted by the pancreas and are majorly involved in the breakdown of protein in the small intestine.

Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.

Before a snowstorm, most cities will place salt on the roads to lower the freezing point of water and to prevent dangerous ice p

Mama L [17]

Answer:

Explanation:

Water tends to move in nature. This movement is facilitated by an osmotic gradient created as a result of OSMOSIS. Osmosis is the movement of water from a region of low solute concentration (high solvent concentration) to a region of high solute concentration (low solute concentration) through a semi-permeable membrane.

Salt contributes to the tonicity of the soil it was sprinkled in the sense that it makes the solute concentration of the soil higher (hypertonic) than that of the plant cell (hypotonic). This creates an osmotic gradient causing the movement of water from the plant cell into the road containing salt in order to form an osmotic balance. The water passes through the cell membrane of the plant cell which acts as the semi-permeable membrane in this case.

The movement of water out of the cell will eventually make the plant cells around that road area shrink (reduce) and likely die, due to loss of water content.

Assume that tall (represented by T) is dominant over short stature (represented by y) in corn. If

aleksklad [387]

Answer:

a. 1 : 1

b. 1 : 1

Explanation:

In this case, a heterozygous tall plant (Ty) is crossed with a homozygous short plant (yy) - which we can deduce as the recessive alleles only exhibit themselves in the absence of the dominant alleles.

The resulting offspring would have the genotypes (refer to attached image):

Ty (Tall)

yy (short)

The genotypic ratio would be - 1:1 (Ty & yy are the genotypes present)

and the phenotypic ratio would be - 1:1 (tall and short are the phenotypes present)

In what phase of meiosis are tetrads separated as homologous chromosomes are pulled to opposite poles of the cell?

Vikentia [17]

The correct answer is C. Anaphase 1.

Anaphase 1 is termed as the phase of meiosis where where tetrads are being separated as homologous chromosomes whereby they are pulled to the opposite poles of the cell.

It is during anaphase 1 stage which is found in meiosis where the cell starts to lengthen. There are two homologs for each chromosome pair which moves towards opposite poles and it separates.

In this phase chromatids remains together as a complete replicated chromosome.

Importance of science in everyday life

Andrew [12]

Explanation:

Science is very important in every activities of our daily life. some of them are,

It is used for cooking as the cooking materials are made with various science ideas.
It is used for buying and selling purposes such as measuring amounts of quantities.
It is used for lightning our house and also run various type of electronic devices to make our life effective through electricity. 
We use science in medical sector as all the requirements in medical sector needs the knowledge and skill of science from medicine to surgery. 
when we make compost manure, there should be bacteria todecompose it.
