Answer:

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.

Why do you think a growing human population means a mass extinction event for Earth’s animals? Cite your evidence.

Lunna [17]

Hello,

A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared, according to research. Scientists analysed both common and rare species and found billions of regional or local populations have been lost. They blame human overpopulation and over consumption for the crisis and warn that it threatens the survival of human civilization, with just a short window of time in which to act.

Hope this helps!!!! Happy Holidays!!!! (:

Which of the following is not a specific adaptation?

SIZIF [17.4K]

Sharp teeth that are constantly replaced would be the answer! In order for it to be a specific adaptation you would need the detail of why the animal has that adaption for example fins for stability:)

In a strand of DNA, each single nucleotide represents a single letter of the DNA code. The following image represents a segment

OleMash [197]

The immense amount of information stored in DNA is coded with just four base nucleotides. These four nucleotides are paired by twos to form complementary DNA chains.

The makeup of DNA is limited to two pairs of nucleotides bases. One of these pairs is a pyrimidine base whilst the other forms a purine base. The four nucleotides that will make up the entire DNA code are:

Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).

A and G will pair to form the purine base, meanwhile, Cytosine pairs with Thymine to form the pyrimidine base. As per the entire DNA code, A will always pair with G.

Whilst C always pairs with T. This is due to the very nature of the nucleotides themselves and will not change throughout the synthesis or duplication of DNA. Therefore, to complete the complementary strand described in the assignment we must match the letter given with its corresponding base pair, using this rule of DNA.
