Answer:

1 and 6 are correct

Explanation:

1. A and B are probably closely related - true, as reflected by their close gene sequences which usually represents a very close genetic relationship

2. B and C are probably closely related - false, if their gene sequences are very different then they are probably not so closely related

3. A and C are probably closely related - false, we know A and B are close, and B and C are very different, therefore A is probably also very different

4. B is probably an outgroup while A and C are sister taxa - false, A and B are highly similar

5. A is probably an outgroup while B and C are sister taxa - false, B and C are very different genetically

6. C is probably an outgroup while A and B are sister taxa - true, we know A and B share similar gene sequences, whereas C is distinct.

Two characteristics of natural wines are that they have a maximum alcohol content of 14% and are ""sparkling"" wines. Apply your

Anna007 [38]

<h2>Alcoholic Fermentation</h2>

Explanation:

Two attributes of regular wines are that they have a most maximum alcohol content of 14% and are "sparkling" wines.
In natural wines, after the ethyl alcohol and are "shimmering" wines.
In regular wines, after the ethyl liquor fixation arrives at 14%, the liquor murders the yeast cells, making aging stop. The bubble or shimmer in wines is the collection of CO2.
Yeast keep on aging sugars until they either come up short on nourishment or the liquor content gets sufficiently high to slaughter them.
The most wine yeasts, 14% is higher than they can tolerate. There are, be that as it may, yeasts that the merchants guarantee can tolerate higher alcoholic rates.

Which part of the influenza virion facilitates interaction between the virus and the to-be-infected eukaryotic host cell?

Radda [10]

The choices are:
A. Matrix protein
B. Hemagglutinin
C. An ion channel
D. Neuraminidase

The right answer is B. Hemaglutinin

Explanation:
Haemagglutinins are triangular rods. They allow the attachment of Influenzaviruses on the target cells of the respiratory tree. In the presence of red blood cells, a haemagglutination (liquid medium) is obtained.
About the other components of Influenza virus:Neuraminidase is a mushroom-shaped spike composed of a tetramer consisting of 4 subunits of a single glycoprotein. At 37 ° C, the neuraminidase destroys the bonds (virus - cells) and thus allows the release of neoformed virions in the external environment: it is elution.
The membrane protein M and the protein subunits of the nucleocapsid are antigenic and are the basis of the classification of Influenzavirus types A, B and C. They induce the synthesis of non-protective antibodies fixing the complement.
