tRNA( Transfer RNA) molecules carry amino acids to the site of protein synthesis
Explanation:
Proteins are the building blocks of the cells. The process of protein synthesis involves transcription and translation of the genetic information stored in the DNA. After the process of transcription which is the process to get RNA molecules from the DNA. After this process, during protein synthesis tRNA carries amino acids to the ribosomes is the structure where protein synthesis takes place.
Low levels of the neurotransmitter serotonin may appear to contribute to aggression. Dopamine and serotonin are the most hormones that are linked with aggression, that is low level of serotonin and high levels of dopamine. The normal effect of serotonin is the inhibitory effect on aggression levels when at normal levels. At the pre-Frontal Cortex serotonin is usually found at its lowest levelsnand increases aggression.
Answer:
3. haploid; diploid
Explanation:
Sperm is male gamete or often called male reproductive cell. During the process of spermatogenesis, reductional division (meiosis) occurs in the spermatocytes and spermatids are formed which further mature to sperms. Thus as a result of meiosis, their chromosome number is reduced to half and thus they become haploid cells. During oogensis, eggs are also formed as a result of meiosis which reduces the chromosome number and so eggs are also haploid.
When during fertilization, these two haploid nucleus of these cells fuse together, they form a diploid zygote.
