All of the following occur during RNA processing EXCEPT______________A) a protective cap is added on the 5' end of the pre-mRNAB) a tail of many adenine nucleotides is added to the 3' end of the mRNAC) the exons and introns are both removed from RNA
Answers
During RNA processing, a protective cap is added to the 5' end of the pre-mRNA, a tail of many adenine nucleotides is added to the 3' end, and only introns are removed. The correct option is C.
The pre-mRNA synthesized during transcription undergoes some processing before being ready for translation. The first thing is the addition of a protective cap to the 5' end and the modification of the 3' end by the addition of a long string of adenine nucleotides.
Thereafter, the pre-mRNA is spliced to remove non-coding sequences, also known as introns. The coding sequences (exons) are joined afterwards before the mRNA is ready to be translated.

Study the pedigree chart. ( picture above)
Which of these can be determined about the trait based on this chart?
○ The trait is recessive. the parents of A were both carriers
○ The trait is recessive. The parents of A were both affected
○ The trait is dominant The parents of te were both affected.
○The trait is dominant The parts of A were both carriers
Answers
Answer: The trait is recessive. the parents of A were both carriers
Explanation: The correct answer should be the trait is recessive.
Since we can only see A mothers tree and she is not affected by the trait she is a carrier.
Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.
So answer it will be "The trait is recessive. the parents of A were both carriers"

If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?
Answers
Answer:3/13
Explanation:
Answer:
x = 1/2 and x = -7
Explanation:
you need to factor
multiply 2 x -7 to get -14
then find factors of -14 that add to give you 13
14 and -1 work
now rewrite the original equation but replace 13x with 14x - 1x
so 2x^2 + 14x - 1x -7 = 0
now factor by grouping
(2x^2 + 14x) (-1x - 7) = 0
factor the greatest common factor out of each group
2x(x + 7) -1(x + 7) = 0
the factors are (2x - 1) (x + 7) = 0
set each factor equal to zero and solve both for x
2x - 1 = 0 x + 7 = 0
+1 +1 - 7 - 7
2x = 1 x = -7
÷2 ÷2
x = 1/2

Answer:
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
The main characteristics of epithelial tissues includes: they compose glands, cover the body surface, form the inner lining of body cavities and line hollow organs.
What is tissue?It is a group of cells having same structure and function.It includes: connective tissue, epithelial tissue, nervous tissue and muscle tissue.What is epithelial tissue?It covers the body surfaces.These are avascular, meaning they do not contain blood vessels.Glands are made up of epithelial tissues.They lines the body's inner cavity and hollow organs.It helps in movement of molecules across the its surfaces.It functions in absorption, secretion and protection.Hence, the correct options are: They compose glands, they cover the body surface, they form the inner lining of body cavities and they line hollow organs.

Joe, age 14, recently fractured his forearm midway between his wrist & elbow. Should his physician be concerned about his epiphyseal plate being affected and causing bone growth to stop?
Answers
Joe's doctor must be concerned that his bone growth will be hampered by damage to the epiphyseal plate.
We can arrive at this answer because:
The epiphyseal plate is a set of cartilage present at the end of long bones, such as the bones present in the forearm.The epiphyseal plate is responsible for the longitudinal and lateral growth of the bone.This growth occurs during childhood and adolescence, for this reason, it is essential to maintain the good integrity of this plaque during this time of life.In the case of Joa, who is still a teenager, a fractured forearm can damage his epiphyseal plate and affect his body's bone growth, so his doctor should be concerned about this.
It is important to note that during adult life, the epiphyseal plate is replaced by an epiphyseal line.

the nerve impulse is an electrical current that travels along dendrites or axons.
Answers
Answer:
i think your answer is true! :)
Explanation:
The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.
Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.
A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.
This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.Therefore, the mentioned statement about the nerve impulse is true.

That capacity exists as an important component of the scientific approach and hypothesis testing. In a scientific context, falsifiability exists sometimes regarded synonymous with testability.
The falsifiable hypothesis can be denied by tests done with the most delinquent technology. The non-falsifiable hypotheses on the other hand can't refuted as tests have confirmed them to be true.
