Answer:

D. Ticks live on and drink blood from a cow.

This is an example of parasitism, where the ticks (parasite) are living off of the blood of the cow, the host animal.

Explanation:

Parasitism is a relationship between organisms. In this relationship, one organism (parasite) lives on or in another organism (host) and gains benefits from the host, causing it some harm.

Parasites are classified as ectoparasites, which live on the body surface of the host (ticks, fleas, leeches, and lice) and endoparasites, which live in the body of the host. Endoparasites are either intercellular, which live inside the host’s body (round worms, tapeworms) or intracellular, which live inside the cells in the host’s body (bacteria or viruses).

Parasites help to control dominant species and has a role in evolution by transferring genetic material between species.

A period in 24-point font (.) is about 1mm in diameter. SARS-CoV-2 has a diameter of 80 nm. The prefix “milli” means 1000, which

Artist 52 [7]

Answer:

A total of 12,500 SARS-CoV-2 viruses

Explanation:

Consider a trillion against a thousand, there exists a difference of a million, which means a nanometer will be a million times smaller as compared to one millimeter:

see below for a milli divided by nano

1/1000 ÷ 1/1000,000,000 = 1000,000,000 ÷ 1000 = 1000,000

(in reference to the hint given in the question statement)

The question puts one millimeter against 80 nanometers. The calculation for this will be given as follows:

1/1000 ÷ 80/1000,000,000 = 1000,000,000 ÷ 80,000 = 12,500

According to the above working, there are 12,500 SARS-Cov-2 viruses thatg can fit into one period.

A major change in evolutionary patterns over long periods of time is best described as:

Amanda [17]

Answer:

A major change over long periods of time is best described as macroevolution.

Explanation:

Macroevolution would be referring to evolution on a larger scale where populations speciate etc. A, B and C are various forms of speciation and microevolution would be referring to smaller changes in evolutionary patterns e.g. in adaptive or physical traits which may not be deemed 'significant' enough to be considered a speciation event.
