Answer:
Option A, helps prevent rapid breakdown of the messenger RNA
Explanation:
The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.
Hence, option A is correct
Hello there.
Fungi, like the one that causes athlete's foot, are considered
A. saprobic
of other organ systems in the human body.
Answer:
nervous system, skeletal system, muscular system, cardiovascular system, urinary system and respiratory system are just a few
Explanation:
Answer:
All systems with short explanation
Circulatory system / Cardiovascular system:
Circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away.
Keeps the body's temperature in a safe range.
Digestive system and Excretory system:
System to absorb nutrients and remove waste via the gastrointestinal tract, including the mouth, esophagus, stomach and intestines.
Eliminates waste from the body.
Endocrine system:
Influences the function of the body using hormones.
Integumentary system / Exocrine system:
Skin, hair, nails, sweat and other exocrine glands
Immune system and lymphatic system:
Defends the body against pathogens that may harm the body.
The system comprising a network of lymphatic vessels that carry a clear fluid called lymph.
Muscular system:
Enables the body to move using muscles.
Nervous system:
Collects and processes information from the senses via nerves and the brain and tells the muscles to contract to cause physical actions.
Renal system and Urinary system
The system where the kidneys filter blood to produce urine, and get rid of waste.
Reproductive system:
The reproductive organs required for the production of offspring.
Respiratory system:
Brings air into and out of the lungs to absorb oxygen and remove carbon dioxide.
Skeletal System:
Bones maintain the structure of the body and its organs.
Answer:
replication fork
Explanation:
The deoxyribonucleic acid (DNA) is a double-stranded helix composed of two long chains of nucleotides. The replication fork is a Y-shaped structure by which both DNA strands are separated in order to be replicated during cell division. In a cell, DNA replication starts at specific sites in the genome referred to as 'origins of replication'. A replication fork is generated by helicase enzymes that unwind and separate the DNA double helix strands by interrupting hydrogen bonds that hold the two DNA strands together. These DNA strands act as templates for the leading and lagging DNA strands. During DNA replication, the leading strand is synthesized continuously in the same direction as the replication fork, while the lagging DNA strand is synthesized in a direction away from the replication fork, in small pieces of DNA called Okazaki fragments.
because the ocean has many more molecules than a pot of water
B
because ocean water has a higher temperature than boiling water
C
because the salt in the ocean causes ocean water to hold on to more heat
D
because molecules of ocean water moves more slowly than those of boiling water
Answer:
A.bevause the ocean had more molecule than a pot of water.
The ocean contains more heat energy than a pot of boiling water because it has many more molecules.
The correct answer is A) because the ocean has many more molecules than a pot of water.
In terms of heat energy, the total amount of energy in a substance is directly proportional to the number of molecules it contains. Therefore, the ocean, which is much larger than a pot of boiling water, contains a significantly higher number of molecules, resulting in more heat energy.
For example, if we compare a small pot of boiling water to the vast ocean, the ocean contains a much larger volume of water, and therefore, a greater number of molecules that contribute to its heat energy.
