Compare and contrast RNA and DNA. (How are they different? How are they similar?)

Answers

Answer 1

Answer:

Differences between RNA and DNA:

Sugar Molecule: RNA contains ribose sugar, while DNA contains deoxyribose sugar.

Bases: RNA uses uracil (U) as a base instead of thymine (T), which is found in DNA.

Structure: RNA is typically single-stranded, whereas DNA is double-stranded, forming a double helix.

Similarities between RNA and DNA:

Nucleotides: Both RNA and DNA are composed of nucleotides, which consist of a phosphate group, a sugar molecule, and a nitrogenous base.

Bases: They both use adenine (A), cytosine (C), and guanine (G) as bases.

Genetic Information: Both carry genetic information and play essential roles in cellular processes like protein synthesis.

Complementary Base Pairing: RNA and DNA use complementary base pairing (A with U in RNA, and A with T in DNA) in various biological processes.

Penicillium notatum is what type of organism?

Answers

Penicillium notatum is a fungi.
Penicillium is a genus of ascomycetous fungi which has a major importance in the natural environmen. It plays an important role in food and drug production as well. Some members of the said genus produce penicillin, a molecule that is used as an antibiotic. These antibiotics kill or stop the growth of certain kinds of bacteria inside the body.

What is stored in carbon bonds

Answers

The correct answer is chemical covalent energy. This energy is stored and when the bonds break the energy is released. You also need energy to break them. The most common form is a single bond but there are examples where there are double and triple bonds when building various compounds.

In chemistry, carbon bonds are covalent bonds formed between carbon atoms in organic compounds. These bonds store and transfer energy in biological molecules and are important for the structure and stability of organic compounds.

In chemistry, carbon bonds refer to the covalent bonds formed between carbon atoms in various organic compounds. Carbon has the unique ability to form stable covalent bonds with other elements, including other carbon atoms.

These bonds are responsible for storing and transferring energy in many biological molecules such as carbohydrates, lipids, and proteins. For example, the carbon bonds in glucose molecules store the energy that is released during cellular respiration and used by cells to perform various functions.

Additionally, carbon bonds play a crucial role in the structure and stability of many organic compounds. The arrangement and number of carbon bonds determine the properties and reactivity of a molecule, making carbon the basis for the vast diversity of organic chemistry.

Select all that apply. The small intestine _____. churns and mashes food into smaller pieces breaks down food to a thin, watery mixture absorbs dissolved food with hundreds of villi stores food

Answers

The answers to the question above are:
The small intestine.......
breaks down food to a thin, watery mixture
absorbs dissolved food with hundreds of villi

The main function of the small intestine is to aide digestion and absorption of nutrients and minerals from food.

Answer: breaks down food to a thin

watery mixture absorbs dissolved food with hundreds of villi stores food

Explanation:

The small intestine is the part of the human digestive system. It appears narrow and coiled. There are many small projections present in the walls of the intestines which helps in absorption of nutrients. These villi increases the surface area of the intestine for digestion of food. The primary function of the small intestine is the break down and digestion of the nutrients present in food at the molecular level. The small intestine is able to absorb the nutrients present in the food and sending them to the bloodstream.

Celia is staring at the clock waiting for school to end so that she can go to track practice. She notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.Part 1: How many radians does the minute hand move from 1:25 to 1:50? (Hint: Find the number of degrees per minute first.)

Answers

Answer:

The minute hand moves $(5\pi)/(6)$ radians.

Step by step explanation:

We know that measure of complete circle is 360 degrees.

In a clock a complete circle means 60 minutes.

$60\text{ min }=360^(\circ)$

$1\text{ min }=(360)/(60)=6^(\circ)$

The minute hand move from 1:25 to 1:50, it means the minute have cover 25 minutes.

$25\text{ min }=(6* 25)^(\circ)$

$25\text{ min }=150^(\circ)$

Therefore minute hand moves 150 degree.

Multiply $(\pi)/(180)$ to convert degree into radian.

$150* (\pi)/(180)=(5\pi)/(6)$

Therefore the minute hand moves $(5\pi)/(6)$ radians.

How many radians does the minute hand move from 1:25 to 1:50?

Calculations are done as follows:

360 ° /60 minutes = 6° per minute
1:25 to 1:50 = 25 minutes

25 minutes x 6° per minute = 150°
150° (π/180) = 5π/6
