The cell is in a hypertonic solution. Because there are more solutes outside the cell, the water will flow outside the cell in order to restore equilibrium.
Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
Answer:
periosteum ----> dense irregular connective tissue
Explanation:
- The periosteum is a dense fibrous membrane that covers the surfaces of bones.
The periosteum consists of two layers-
1. Outer fibrous layer
2. Inner cellular layer
- It is mainly composed of dense irregular connective tissue along with a layer of simple squamous epithelium.
- The function of periosteum is to cover the surface of all the bones except those surfaces that are covered with cartilage such as joints and tendons and ligaments.
Answer:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
