Answer:
In the first stage of sexual reproduction, "meiosis", the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During "fertilisation", haploid gametes come together to form a diploid zygote, and the original number of chromosomes is rest
Explanation:
Explanation:
In gases, the forces between particles are very weak. This explains why the particles in gases are not neatly arranged. They are not held together tightly and there are large spaces between them. These spaces are much larger than in the solid and liquid state.
Answer:
the three-base sequence of mRNA
Explanation:
Translation is the process of formation of proteins. Translation process is achieved with the help of ribosome, which links amino acids in the order defined by messenger RNA (mRNA), using RNA (tRNA) transfer molecules to hold amino acids and read three nucleotides at a time of the mRNA.
The three-base sequence are present in mRNA called codons or mRNA nucleotide triplet sequences are specific to a amino acids for proper function. For exmaple: AUG codon , specifies the amino acid methionine which acts as starts codon and initiate the process of translation.
Hence, during translation, the characteristic that represents the three base sequences of mRNA is related to the coding of single amino acid.
Because they take place at an atomic level and are unable to be seen by the human eye
Answer:
Damage to the ischial tuberosity would compromise stand and walk.
Explanation:
The ischium is the lower component of the coxal bone, which is part of the hip or pelvic girdle. The ischial tuberosity is located in the upper back part of the ischium, being the place where the tendons of important muscles of the lower limb are inserted.
The four major muscles that have their insertion into the ischial tuberosity are
- <em>Major adductor of the thigh
.</em>
- <em>Biceps crural.
</em>
- <em>Semimembranous.
</em>
- <em>Semitendinous.
</em>
The individual and joint function of these muscles allows for stability of the lower limb with respect to the hip, flexion and extension movements of the thigh and leg, essential for standing and walking.
An injury of the ischial tuberosity would result in a significant limitation in standing and walking.
