Answer:

<h2>The living organisms of the past.</h2><h2>Minerals more abundant in the soil of the past.</h2>

Explanation:

Sedimentary rocks are formed by mineral and organic particles that were united by erosion. So, this particles bring useful information about some variables from the past that help to estimate age of existence and an idea of how was life back then.

A huge example are fossils, these are studied by palaeontologists, to study animals that existed before.

zzz [600]

Option (III) .Cephalization, the clustering of neurons and interneurons in the anterior part of the animal, is apparent in <u>Planaria.</u>

What is planaria?

  • Planaria is a genus of planarians in the family Planariidae.
  • When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
  • Currently the genus Planaria is defined as freshwater triclads with oviducts that unite to form a common oviduct without embracing the bursa copulatrix and with an adenodactyl present in the male atrium.
  • The testes occur along the whole body.
  • Planaria originally have habitats in dark, murky water which results in such sensitivity .
  • They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
  • Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the
gregori [183]

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

Ne4ueva [31]

Answer:

E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.

Explanation:

Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
