Answer:

First year and second year.

Explanation:

The development of the infants starts from the day of the birth. The development of the baby includes the different stages and the development occurs at each month with physical and physiological changes.

During the first year of the development the child knows how to stand, walk, sit and react on the other people expressions. During the second year of the child development, the child knows about the balancing of their body and feet in the squat position.

Thus, the answer is first year and second year.

Answer: within the first year, within the second year

Explanation:

Many toddlers start to sit, stand and walk by the age of 9 to 15 months of age. These are because of the changes that occur in the brain and the spinal cord. By the age of two the brain develops coordination with the muscles of the body and the infant establishes balance on the feet and hip muscles becomes strong that aids in achieving the squatting position.

Cite the three main types of RNA and describe briefly the function of each.
sveticcg [70]

Answer:

mRNA: Carry genetic information from DNA to protein; serve as template for protein synthesis.

tRNA: Serves as adapter molecule and deliver specific amino acid from the cell pool to the mRNA-ribosome complex.

rRNA: Structural component of ribosomes.

Explanation:

There are three types of nongenetic RNAs: mRNA, tRNA, and rRNA.  

1. The messenger RNA (mRNA) is formed by the process of transcription in the nucleus. Transcription uses template strand of DNA to specify the nucleotide sequence in mRNA. The mRNA enters cytoplasm to join ribosomes. The nucleotide sequence of mRNA serves as a template and specifies the amino acid sequence of proteins.  

2. The transfer RNA (tRNA) serves as an adapter molecule during the process of protein synthesis and binds to the specific amino acids to deliver them to the protein-synthesizing machinery. The anticodon of tRNA binds to the complementary mRNA codons.  

3. The ribosomal RNA (rRNA) serves as structural components for ribosomes. Each of the subunits of ribosomes is made up of rRNA and proteins.

Paladinen [302]

Answer:

About 100 times more than other planets.

Explanation:

The Sun would be about 100 times bigger than the earth planet in the scaled-down model of the solar system because in the reality the size of sun is 109 times more than the earth so making a model more perfect and nearer to reality we have to maintain the diameter of the sun more than 100 times than the earth and other planets.
