The answer is nonvascular plants.
The plants that are similar to algae are
called nonvascular plants. They are the plants small plants with the absence of
vascular system. They do not have roots. They have small hair likes that insert
to substrate to keep the plants in place instead of roots. These are called
rhizoids.
Answer:
The correct answer is c the mutant will show decreased levels of gene expression.
Explanation:
Histone acetyl transferase is an enzyme that helps in the transfer of acetyl group to the epsilon -NH2 group of lysine reside of histone proteins that surrounds the DNA molecule of chromosome.
This results to make the target DNA more assecible for transcription mediated by RNA polymerase resulting the gene expression.
On the other hand the mutant in which histones are not acetylated,transcription rate decreases as the non acetylated DNA is less assecible to RNA polymerase.
D. is correct: Koalas evolved after trout.
(A is false, B is also false bc amoeba are unicellular, C is false too, they are definitely not in the same class)
Isotopes
Atoms of the same element; number of protons remain the same, number of neutrons vary. Chemical properties remain the same. Atomic mass varies.
Na sodium with 11 neutrons = atomic mass of 22
With 22 neutrons the mass is 23.
Both have 11 protons in the nucleus.
it's (+/-) 90 degrees. in total it's 180 but the equator is at zero and the two hemispheres have 90 each
