Answer:

See the answer below

Explanation:

Since bacteria are prokaryotes, they have no nucleus and membrane-bound organelles. The outside of a bacterial cell is protected by a structure called a capsule. The cell wall provides a rigid structure that gives the cell its shape. The cell membrane helps to transport ions, nutrients, and waste. The plasmids allow DNA to be transferred from one bacterium to another.

<em>The bacteria are microscopic organisms that are generally classified as prokaryotes. The prokaryotes lack nucleus and other membrane-bound organelles, unlike the eukaryotes. The bacteria cells are enclosed in a protective structure known as the capsule. Immediately after the capsule is the cell wall whose components vary depending on whether the bacteria is Gram-positive or negative. </em>

<em>Towards the innermost part of the cell, after the cell wall is the cell membrane. It acts as a channel for the transport of materials in and out of the cell. Some bacteria cells have short, circular, extrachromosomal DNA known as plasmids which can be transferred from one cell to another.</em>

Which of the four main layers of Earth rotate in different directions to produce Earth's magnetic field.?
mihalych1998 [28]

Answer:

Earth has various layers: the covering, the mantle, the fluid outer core and the inner core.

The Earth's attractive field controls the course and speed at which Earth's internal and external centers turn, despite the fact that they move in inverse ways, new research proposes.

"Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA
Dima020 [189]

Answer:

G - 21%

T - 29%

A - 29%

Explanation:

Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.

From the information given, C is 21%

Therefore G is also 21% of the genome as  C is bound to G, the therefore are the same proportion.

C and G make up 42% of the genome (that 21% + 21%).

The remaining 58% (100%-42%) is made up of A + T

Similarly the proportion of A is equal to that of T,

Hence A is 29% (half of 58%) and T is 29%.
