Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn't fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.

Which of these effectors is not directly controlled by the autonomic nervous system?

prohojiy [21]

Answer:

d. Skeletal muscle

Explanation:

There are two components of efferent nervous system.

Somatic nervous system
Autonomic nervous system

SOMATIC NERVOUS SYSTEM:

Somatic nervous is one of the components of efferent/motor nervous system.

It controls voluntary activities. It involves the control of skeletal muscles.

It is composed of the motor neuron and the innervating muscle.

AUTONOMIC NERVOUS SYSTEM:

Autonomic nervous system is the other efferent/motor system of the body. It controls the involuntary activities. It involves the control of cardiac muscle, glands and smooth muscles of the body.

It is composed of 2 neurons; preganglionic and postganglionic neurons.

Autonomic nervous system is further divided into:

Sympathetic nervous system (it is responsible for flight and fight responses)
Parasympathetic Nervous system (it is responsible for rest and digestion)
Enteric division ( controls Gastrointestinal system)

QUESTION:

d. skeletal muscle

This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.

What is the mRNA sequence for the template strand DNA sequence?3' TACAAACTAGAA 5' *

True [87]

Answer:

5' AUGUUUGAUCUU 3'

Explanation:

The nucleotide bases for mRNA are Adenine, Guanine, Cytosine, and Uracil. Uracil replaces Thymine (it's DNA counterpart). From this, you can eliminate options C and D.

Then it is just matching pairs: Adenine = Uracil , Cytosine = Guanine.
