What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct

Use what you know about DNA to predict some of the physical properties of DNA that you will observe.

tiny-mole [99]

Answer:

DNA has double helical structure in which the two strands run antiparallel and are connected through complementary base pair

Explanation:

Some of the physical properties of DNA are

a) It comprises of two strands that attaches with each other in a spiral helical manner thereby giving it a double-stranded helical structure

b) The two strand join each other through complementary base pairing in which A pairs with T and C pairs with G.

c) There is a phosphate group at 5' end and a hydroxyl group at 3' end.

d) Strands are antiparallel as one of the strand run in 5′to 3′direction and the other runs in a 3′ to 5′ direction.

sattari [20]

Answer:

The correct answer is the D option 5' A C G U U A G G 3'

Explanation:

The chemical ending orientation of a single strand of nucleic acid into a single strand of DNA or RNA is the chemical convention of naming carbon atoms in the nucleotide sugar-ring,

It means that there will be a 5′-end (usually pronounced "five prime end" ), which frequently contains a phosphate group attached to the 5′ carbon of the ribose ring, and a 3′-end (usually pronounced "three prime end"), which typically is unmodified from the ribose -OH substituent.
