Answer:
When the level of calcium ions declines the sarcoplasm stops the sliding.
Explanation:
Sarcoplasm can be described as the cytoplasm for the cells of muscles. It contains important structures such as the myofibrils.
The following steps would occur when the level of calcium ions would decline:
The sarcoplasm would stop the sliding of the thin filaments.
The actin filaments would be migrated in the M line
This would lead the bands in the I region to shorten.
The Z region would compress.
The H region would diminish.
Answer: A flood could hit Tokyo so quickly that the levee could break. In a short amount of time, this breach, or break, could cause severe damage to Tokyo’s infrastructure, like a flood in a Hollywood disaster movie. Because Tokyo is home to a large population, a flood could cause massive damage to homes, businesses, and life.
Explanation: Because the floods happened recently there.
Genotypes of the dog color are:
BB dominant homozygous-brown phenotype
bb recessive homozygous-white phenotype
Bb heterozygous-tan phenotype
Cross between brown and pan dog would be:
P: BB x Bb
F1: BB Bb BB Bb
The ratio would be 1:1 (brown dog:pan dog).
The question is incomplete as it does not have the options which are:
(a)DNA (b)tRNA (c)rRNA (d)mRNA
Answer:
Option-mRNA
Explanation:
The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.
The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.
This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.
Thus, mRNA is correct.
The fossils from
Australopithecus provide evidence for evolution because some parts of the bone
that contains the DNA of it can be identified as this type of animal. They can
be detected through the use of carbon dating devices.
