What is transcription in biology

Answers

Answer 1

Answer:

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

2. Give a specific example of motion.

Answers

Explanation:

motion means displacement or change in the position of an object over time. It can be described in terms of displacement, distance, velocity etc. ... eg pushing a block is an example of linear motion, opening a door is an example of rotation, rotating stone with attached thread is an example of a circular motion.

New Zealand has a population of 4,326,380 and has an area of 103,736 while Australia has an area of 2,967,909 miles and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population?

Answers

Since the country has a smaller area and a large amount of people (although smaller than Australia) the ratio of land to people in New Zealand is much larger than the ration of land to people in Australia.

A, plant cells have rigid cell walls and no centrioles! :)

Glucose is broken down in different ways both in the presence and in the absence of oxygen.Using the table for reference, which reaction precedes each member of the reaction set in column one?
Reaction set Preceded by
glycolysis A
Krebs cycle B
ETS C
lactic acid fermentation D

A.
A. photosynthesis in plants
B. glycolysis
C. glycolysis
D. Krebs cycle

B.
A. glycolysis
B. Krebs cycle
C. photosynthesis in plants
D. glycolysis

C.
A. glycolysis
B. Krebs cycle
C. glycolysis
D. Krebs cycle

D.
A. photosynthesis in plants
B. glycolysis
C. Krebs cycle
D. glycolysis

Answers

For the given reaction set:

Glycolysis (A)
Krebs cycle (B)
ETS (C)
lactic acid fermentation (D)

Each of the elements of the reaction set is preceded by corresponding elements of set D which consists of:

A. photosynthesis in plants
B. glycolysis
C. Krebs cycle
D. glycolysis

To summarize the order of the reactions:

photosynthesis in plants > glycolysis > Kreb's cycle (aerobic respiration) or lactic acid fermentation (anaerobic respiration) > Electron Transport Chain (ETC)

Aerobic respiration:
Photosynthesis produces glucose, which is used in glycolysis. Glycolysis produces ATP, NADH, and pyruvate. Pyruvate is then used in the Kreb's cycle to produce NADH, FADH2, ATP, and CO2. The ETC then uses the NADH and FADH2 to produce energy.

Anaerobic respiration:
The same process is followed until glycolysis. The pyruvate produced from glycolysis is used in the lactic acid fermentation process to produce lactic acid.

Correct answer is

A. NAD+

B. ATP

C. Pyruvic Acid, ATP, NADH

D. ATP, FADH2, NADH

Which of the following describes a chemical property of a metal?A. reacts with acid
B. conducts electricity
C. attracted to a magnet
D. high melting point

Answers

Answer: The correct answer option (A).

Explanation:

Chemical properties are the properties which are observed in a chemical reaction like change in arrangement in atoms or change in identity of the substance.

Metals reacts with acid to form salts and hydrogen gas. In which chemical composition of pure metal changes during the chemical reaction. So, yes it is a chemical property of metals.

Whereas conducting electricity, property to get attracted by magnet and high melting point doesn't changes the arrangement of an atoms which means they are not chemical properties of metals but are physical properties of metal.

Hence, the correct answer option (A).

answer is react to acid
