Answer:
RNA synthesis proceed in 5' to 3' direction.
Explanation:
The process of formation of RNA molecule from the DNA template is known as transcription. The transcription process is necessary for the gene expression.
The process of RNA synthesis always occur in the 5' to 3' direction. The RNA polymerase moves from the 3' strand and adds the polynucleotide and RNA synthesis in 5' to 3' direction. The anti parallel nature of the nucleotide causes the RNA synthesis in 5' to 3' direction.
An organism that can live in only one particular environment or that can survive on only one type of food would be called a specialist.
All you need to look through the human body systems you had in the unit and explain how they make you living, rather than dead. What body systems do you have that make you a living human being.
1. Your Cardiovascular system. It keeps your body and cells supplied with oxygen so they can stay alive.
2. Your nervous system. It allows your body to take outside stimuli and allow your brain to process and react to it.
3. Your Digestive system. It allows you to extract the energy from other living things and use it to power your body.
Answer:
Q1) True
Q2) Metabolism
Q3) Physiological response
Explanation:
Q1) Energy cannot be created (first law of thermodynamics). Life needs an energy source to transform. Without the energy from the sun or any other sources, life would cease to exist. (True)
Q2) An organism chemical reactions consist, in general, breaking down complex molecules (catabolism) releasing energy or to form complex structures from simpler molecules (anabolism) which require energy . The total of this reactions is called metabolism.
Q3) Hibernation is physiological state of inactivity and metabolic depression in some organisms, which result as a response to low temperatures and unavailability of food.
<u>Answer</u>: Large collection of stars, gas, and dust held together by gravity.
<u>Explanation:</u>
- The name <em>galaxy</em> has been derived from the word <em>galaxies</em> which is a Greek word meaning milky.
- In simple words a galaxy is a collection of a large number of stars, however, to be more precise <em>a galaxy is a gravity-bound collection of stars, dust, gas, dark matter and stellar remnants. </em>
- There are different types of galaxies found in various shapes and size, some of the most common shapes being elliptical, irregular and spiral.
- An example is the milky way galaxy that contains our solar system.
