Mars2501 [29]

Answer:

Explanation:

This is because, during lytic cycle,

During the lytic cycle, genome willing f the virus always undergo replication and transcription and the enzymes then degraded the bacteria chromosomes which has been coded by the viral genome to produce deoxyribonucleotides that acts as monomers to in order to produce more viral DNA so that virus will be replicated the more.

The virus find it's way into the the bacteria, then take over the whole macromolecular production and degrade components that are in existence in bacteria so as to get new materials to replicate alot of copies of itself.

What is the formula for this compound?

Delicious77 [7]

Answer:

Symbols: Each capitol letter means that there is a new element

Li2

Cl3

is made of lithium and chlorine

Na2

SO4 is made of sodium, sulfur and oxygen

Chemical Formulas are used to describe a chemical compound, when two or more atoms

combine to form a new substance.

A combination of chemical symbols shows the elements that make up a chemical compound.

The chemical formula for water is H2O

H stands for HYDROGEN.

O stands for OXYGEN.

Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of

atoms of that element. If an element does not have a subscript, then it is understood that the

subscript is 1.

Li2Cl3 has two lithium atoms and three chlorine atoms

Na2SO4 has two atoms of sodium, one atom of sulfur, and four atoms of oxygen

A subscript outside a parenthesis affects all the elements inside the parenthesis. Multiply the

subscript on the outside by the subscript of the atoms on the inside.

Al (SO4)3 has 1 atom of aluminum, 3 atoms of sulfur, and 12 atoms of oxygen.

Coefficients are full size numbers in front of chemical formula. The coefficient multiplies everything

in the formula. It also represents the number of molecules of that compound.

2Na2

SO4 has 4 sodium atoms, 2 sulphur atoms, and 8 oxygen atoms.

2Al (SO4)

3 has 2 aluminum atoms, 6 sulfur atoms, and 24 oxygen atoms

When you count atoms, remember to multiply the coefficient number and the subscript number to find

the number of atoms of that element.

Dafna11 [192]

Correct question: A fast swimming strong body fish such as a <u>salmon</u> which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file

Answer:

Source of a river zone

Explanation:

The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.

Rivers belong to lotic environments, characterized by constant moving water.

Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.
Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom.
Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish.

Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.

Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.
