Answer:
D. Testicle
Explanation:
The testicle releases the male hormone testosterone.
The statement above is TRUE.
The electrochemical gradient in the chloroplast is a gradient of electrochemical potential of ions which move across the membrane of the chloroplast during the photosynthesis process. The proton gradient across the thylakoid membrane drives the ATP synthesis during photosynthesis.
Answer:
Both show the characteristic of a living organism
Explanation:
A thing can be considered a living thing if it fulfills the criterion of a living organism or in simple terms the characteristics of a living organism. In the given question, the two features that are growth in the mass and size of the sliver are measured and observed through the microscope.
Since the growth is the characteristic feature of the living organism and the substance fulfills this condition therefore the specimen is considered a living organism.
Thus, both show the characteristic of a living organism is correct.
Answer:
When two people create the next generation if the trait is dominant and possessed by one it will commonly be passed down if it is passive then it is a bit less likely to be passe down unless both parents share the trait as 50% of genetic traits come from both sides.
Explanation:
Answer:
microRNAs
Explanation:
Within the cell, there are different types of regulatory non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), small-interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs), long ncRNAs, etc., which are able to regulate gene expression. miRNAs are evolutionary conserved small ncRNAs (typically 18-23 nucleotides in length) known to inhibit gene expression by base-pairing with complementary target mRNAs, and thus trigger RNA interference (RNAi) pathways (e.g., mRNA degradation, inhibition of translation, etc). These miRNAs form part of a ribonucleoprotein complex named RNA-induced silencing complex (RISC) that acts to trigger RNAi mechanisms.
