Why should the distillation apparatus have an opening to the atmosphere at the end?

Len [333]

Distillation is one of the processes that are used in the laboratory to remove impurities from substances. Distillation employs the differences in the boiling points of two liquids to separate them. The distillation apparatus must have an opening to the atmosphere at an end in order to avoid developing a dangerously high pressure within the system when heat is applied.<span />

2. The cytoskeleton of animal cells includes three types of proteins, and the cytoskeleton of plant cells includes two types of

sineoko [7]

Answer:

A. Actin filaments and microtubules

B. intermediate filaments

Explanation:

Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.

What micromolecule is produced during photosynthesis for plant food?

Marina86 [1]

<h3><u>Answer;</u></h3>

Carbohydrate

<h3><u>Explanation;</u></h3>

Carbohydrate is the macromolecule produced during photosynthesis for plant food. Carbohydrate is among the four major macromolecules, others being, nucleic acid, lipids, and proteins.
During photosynthesis energy from the sun, together with water and carbon dioxide are used to make nutrients or organic compounds such as simple sugars like glucose.
By using the energy from the sunlight and absorbing the water molecules from the soil, the plant produces glucose molecules. The glucose is a carbohydrate.

This table shows the codons found in messenger RNA (attached). Using this information, what sequence of nucleotides in the templ

Rashid [163]

Answer:

Explanation:

The correct answer would be <u>option A</u> - GUA-CAU-ACC

<em>Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible</em>

<em>For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.</em>

<em>For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.</em>

Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC
