Answer:
D. DNA contains uracil.
Explanation:
Uracil is in RNA. DNA has Thymine.
Considering the answers
A. GTT
B. TCT
C. TCC
D. GCA
The answer would be A. GTT
A sequence of amino acids in a protein determines its functions. The DNA sequence of a gene determines the amino acid sequence of the resulting protein, therefore, any changes in DNA sequences can result in changes in protein function.
Answer:
relaxation occurs
Explanation:
Muscle contraction, in addition to being responsible for locomotion and various other types of body movements, also promotes the movement of internal organs, such as heartbeat, artery pulsation, transit of the bolus through the digestive tract, among others.
Such processes are made possible by the shortening capacity of myofibrils, which are cytoplasmic filaments of muscle cells. Such myofibrils are made up of several types of proteins, with actin and myosin being the most abundant.
Myosin makes up the thick filaments and is classified as a mechanochemical enzyme or motor protein, because it is able to convert chemical energy into mechanical energy, useful for the mechanism of muscle contraction. When the myosin cycling process generates less stress than the load, muscle relaxation occurs.
Answer: monocular cue
Explanation:
The key reason one don't lose sense of depth is because of monocular cue. Our brain can still detect the actual position of the object with helps of cues even if one eye is closed.
Such cues include (but are not limited to):
- Linear perspective - the fact that additional objects ultimately travel to a single point (i.e. two roads that converge into a single point in the distance)
- Texture - objects closer to you will have more complex texture compared to objects further away from
- Interposition - objects closer to you will be farther away from objects
- Accommodation - as you look closely at items, your eyes need to accommodate and concentrate on them using your eye muscles, giving your eyes an idea of where the object is located.
Hence, Monocular Cues are used by using one eye to help sense distance.
