Adenine and thymine are complementary bases, as well as cytosine and guanine. Complementary bases bind always with each other, and never with another base. Cytosine and guanine are joined together by 3 hydrogen bonds and thymine with adenine with 2 hydrogen bonds

The first commercial application of genetic engineering was the use of bacteria to make insulin, a medicine needed by diabetics.
Murljashka [212]

Answer:

The question is incomplete, it lacks options. The options are:

A) It has made the demand for insulin decrease.

B) It has made the incidence of diabetes decrease.

C) It has made it easier for diabetics to inject themselves with insulin.

D) It has made insulin cheaper and more readily available.

The answer is D

Explanation:

Genetic engineering is a biotechnological procedure that involves the transfer of genes from one organism to another using biotechnology. In this case, bacteria cells are said to be genetically modified because their genetic content is tampered with and the genes that produces the insulin protein in humans is added into their genome. Hence, they transcribe and translate this gene to produce the protein-insulin.

Diabetic patients cannot produce this insulin in their system. Hence, the insulin produced from this genetically modified bacteria cells can be administered to diabetics via injection. This genetically modified way of producing insulin has proven to be a far better option to the previous practice of slaughtering cattles and pigs to obtain this protein because the GM method allows insulin to be produced in large amounts making it available and cheaper to diabetics.

Volume is defined as the amount of mass that an object has? True or false
maria [59]

Answer:

False

Explanation:

Mass and volume are two different quantities. In fact:

- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.

- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters (m^3).

Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

d=\frac{m}{V}

where

m is the mass

V is the volume

So the density of a substance represents the amount of mass contained in a certain volume of the substance.

What are the essential components for controlling Type II diabetes? What are some differences between Type I diabetes and Type I
Nata [24]
A healthy lifestyle that includes adequate rest, exercise, and a balanced diet.

Type I is insulin-dependent; Type II is non-insulin-dependent. Type I requires injectable insulin to treat; Type II can be treated without insulin with correct diet and exercise. A person is usually born with Type I diabetes, whereas Type II has been linked to obesity and poor dietary habits.90 calories; one fat exchange = 45 calories. 

Exchange lists can be used by diabetics to give freedom of choice in what they can have to eat or drink. It allows diabetics to select types and amounts of foods while maintaining a healthy calorie level.30 grams or 2 carbs, because two slices of bread 2 starch servings.

Carbohydrate counting can help people control their carbohydrate intake, which helps control blood sugar. It allows flexibility in menu planning because no food is excluded, and only carbohydrates are counted.
