Answer:
In the sequence of 8, it would be 4 (possible bases) to the power of 8 because you need to multiply 4, eight times for the number of sequences. Therefore, the answer is 65, 536 possible sequences.
There are 65,536 different possible sequences in a DNA strand consisting of eight pairs of nitrogenous bases.
We have a DNA strand consisting of eight pairs of nitrogenous bases and we want to know how many different sequences of eight bases can we make, that is, how many combinations are possible.In DNA, there are 4 kinds of nitrogenous bases: Adenine (A), Guanine (G), Thymine (T) and Cytosine (C).Each position (P) can be occupied by any of the 4 bases (B). Since there are 8 positions, and the bases can be repeated, we can calculate the total number of different sequences (N) using the following expression.
[tex]N = B^{P} = 4^{8} = 65,536[/tex]
There are 65,536 different possible sequences in a DNA strand consisting of eight pairs of nitrogenous bases.

Tell 2 human activities by which carbon can enter the atmosphere as
CO2 during the carbon cycle:
Answer:
Activity 1. Breathing (Humans breathe out CO2)
Activity 2. Burning (Which releases CO2 into the atmosphere
Explanation:
The two human activities by which carbon can enter the atmosphere as [tex]CO_2[/tex] during the carbon cycle are:
Breathing (Respiration): Breath out [tex]CO_2[/tex] in the atmosphere. Burning/Fire: causes the release of [tex]CO_2[/tex] in the environment. What is the Carbon cycle?The flow of carbon and its compounds by different means in the atmosphere is known as the Carbon cycle.
Human activities can play an important role in the cycling of carbon into the atmosphere. Each and every step of the carbon cycle directly or indirectly depend on human activities. For example Fire, respiration, industrial wastes, automobiles, etc.
Therefore, above are the two human activities by which carbon can enter the atmosphere [tex]CO_2[/tex] during the carbon cycle are described briefly.

Answer:
Catalase
Explanation:
Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water (H2O) and oxygen gas (O2).
A catalyst is a substance that lowers the activation energy required for a chemical reaction, and therefore increases the rate of the reaction without being used up in the process.

Explain how you could find out whether or not an unknown liquid is water.
We can use the physical properties of water such as density, melting point and boiling point, etc to determine if a liquid is water. Water has a density of 1 gm/cm^3 or 1000 kg/m^3. We can measure the mass of one cm^3 or 1 m^3 of the unknown liquid and check against the mass of equivalent volume of water.

The most northern of the islands is the OLDEST. The most southern of the islands is the YOUNGEST. The most southern of the islands has experienced LESS weathering.
How does Islands formed?Oceanic islands are those islands which rise to the surface of land from the floors of the ocean basins. Continental islands are simply the unsubmerged parts of continental shelf which are entirely surrounded by water from all the sides. Many of the larger islands of the world are of the continental type only.
As volcanoes erupt, they build up different layers of lava which may eventually break the water surface. When the tops of these volcanoes appear above the water level, an island is formed. While the volcano is still beneath the ocean surface, it is known as a seamount. Oceanic islands can form from the different types of volcanoes.

Put the steps of DNA Replication in the correct order
Answer: Initiation Elongation and termination
Explanation:
There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
The correct order for DNA replication is B, A, C and D.
During DNA replication, first the DNA double helix break down the middle part between base pairs. The enzyme DNA polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.
After that a complementary strand is produced for each of the two strands of the original double helix. Thus two new identical DNA molecules have been produced and the replication process is finally completed.
