1 answer:
Darina [25.2K]3 years ago
3 0

Answer:

\boxed {\tt 3}

Explanation:

An element only has <u>one</u> type of atom and cannot be broken down by chemical means.

Let's analyze the answer choices.

1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.

2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.

3. This has one type of atoms, so it is an element.  

Therefore the best answer choice is 3.

uranmaximum [27]

Answer:

Bacteriophages that induce bacterial cell lysis are called​ virulent phages.

Explanation:

Bacteriophages correspond to viruses with an affinity for prokaryotic cells to be used as hosts for replication. They act both by invading the bacterial cell and by introducing their genetic material into it.

Some bacteriophages are capable of lysing or destroying the host bacterial cell after replication of their genetic material, receiving the name of virulent phages.

Which part of the nephron receives fluid directly from the glomerular capsular space?
Gala2k [10]

The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. The glomerulus is the site in the nephron where fluid and solutes are filtered out of the blood to form a glomerular filtrate. The proximal and distal tubules, the loop of Henle, and the collecting ducts are sites for the reabsorption of water and ions. Fluid and small solutes are forced under pressure to flow from the glomerulus into the capsular space of the glomerular capsule.

Reabsorption as this filtrate passes through the tubules, specific substances are reabsorbed back into the blood of the peritubular capillaries. Bowman's capsule surrounds the glomerular capillary loops and participates in the filtration of blood from the glomerular capillaries.

If a TRNA had a AGC anticodon it could attach a
Contact [7]

A transference RNA (tRNA) is an adapter molecule that decodes a codon messenger RNA (mRNA) during the synthesis of a polypeptide chain. These molecules (tRNAs) play a fundamental role during translation.

  • If a tRNA had an AGC anticodon it could attach a codon having the sequence UCG.

  • During translation, tRNAs act at specific sites in a ribosome to synthesize a polypeptide chain (i.e., a protein) from an mRNA sequence.

  • The anticodon of the tRNA binds by base complementary to a triplet of nucleotides or 'codon' in the messenger RNA (mRNA) during protein synthesis (i.e., translation).

  • According to the base complementarity rules, in RNA, Adenine always pairs with Uracile (Thymine in DNA), whereas Guanine always pairs with Cytosine.
