Answer: c. proteasome
Explanation:
Proteasomes are extremely important multi-catalytic proteases and are involved in various cellular functions. The proteasome is an essential component of eukaryotic cells and is responsible for the ATP-dependent proteolytic degradation of most cellular proteins. They are present in the nucleus and cytosol and can represent up to 1% of total cell proteins. Proteasomes generally degrade proteins to small peptides, most of which are rapidly hydrolyzed by cytoplasmic exopeptidases. It catalyzes the rapid degradation of many enzymes, regulatory proteins, and eliminates abnormal proteins resulting from mutation or damaged proteins. The inability of this cellular organelle can lead to neurodegenerative diseases, such as Parkinson´s disease.
It is A: Uracil
DNA and RNA is my favorite subject in Biology and Anatomy
B. CONSISTENCY.
Soil consistency is most dependent on soil moisture.
Soil consistency are identifies as Moist Soil, Wet Soil, and Dry Soil.
Moist soil are loose when dry or wet, friable (using gentle pressure), and firm (using moderate pressure)
Wet soil are plastic and sticky.
Dry soil are either soft or hard.
Answer:
Dorsal nerve cord
Explanation:
For chordates, based on the particular life cycle there are at, they could either posses a NOTOCORD or a DORSAL NERVE CORD.
Chordates can be fishes, reptiles, manmals , vertebrates amphibians, birds etc.
Please let me add that, CHORDATES are mostly if not entirely vertebrates and as such possess DORSAL NERVE CORD.
N.B
Ventral nerve cord are for invertebrates
Answer:
D
Explanation:
plants make use of solar energy(energy from the sun )to produce oxygen using carbon dioxide(CO2)
