Ø A large taxa, includes insects and a small group of wingless arthropods.

Ø Body plan: 3 parts, head, thorax and abdomen.

Ø Head with six segments.

Ø Thorax with three pairs of jointed legs (hence the name hexapoda)

Ø Head bears a presegmental acron.

Ø Acron bears compound eyes.

The correct answers are:

1. Barrier island;

The barrier islands are island formed from the deposition of sediments, relatively close to the coastline. They are often in a linear shape, parallel to the shore, and being attractive tourist places.

2. Steep and rapidly exposed;

The cliffs are rocky structures that appear on the coastline itself. They are very steep, vertical, or even bent over the water bellow them, and they rise sharply above the water.

3. False;

The coastlines are changing constantly. The reason for that are the weathering and erosion processes, the deposition of sediments, as well as the rise or fall of the sea level.

Different evolution theory of living organism​
Neporo4naja [7]

Answer:

<em>(I) Lamarckism or Theory of Inheritance of Acquired characters.</em>

This theory is based on the comparison between the contemporary species of Jean Baptiste de Lamarck's time to fossil records.

<em>(II) Darwinism or Theory of Natural Selection.</em>

Charles Darwin made an extensive study of nature for over 20 years, especially in 1831-1836 when he went on a voyage on the famous ship “H.M.S. Beagle” and explored South America, the Galapagos Islands and other islands.

<em>(III) Mutation theory of De Vries.</em>

The mutation theory of evolution was proposed by a Dutch botanist, Hugo de Vries (1848-1935 A.D.) in 1901 A.D. in his book entitled “Species and Varieties, Their Origin by Mutation”. He worked on evening primrose (Oenothera lamarckiana).

<em>(IV) Neo-Darwinism or Modern concept or Synthetic theory of evolution.</em>

The detailed studies of Lamarckism, Darwinism and Mutation theory of evolution showed that no single theory is fully satisfactory. Neo-Darwinism is a modified version of theory of Natural Selection and is a sort of reconciliation between Darwin’s and de Vries theories.

2. In order for the lagging strand to elongate during DNA replication, it must
devlian [24]

Answer:B) progress towards the replication fork.

Explanation:

Replication fork is a point on the parental DNA where the DNA is being unwound and separated; and the separated strands are being replicated. Synthesis of a new DNA strand occurs in a 5' -> 3' direction, as the DNA strand serving as the template is read from its 3' -> 5' direction. During replication, two strands of DNA are synthesized: The leading strand is synthesized continuously in the same direction as the replication fork movement while the lagging strand is synthesized discontinuously in the direction opposite to the direction of fork movement, that is, towards the replication fork. The lagging strand is synthesized in short fragments known as Okazaki fragments.

A _____ is used to reveal the detailed internal structure of a cell.
gladu [14]

Answer:

The correct answer will be- Transmission electron microscope

Explanation:

A Microscope is an optical instrument designed to view the microscopic things which could be living or non-living around us.

The internal structure of a microscope can be viewed by a light microscope mainly dark-field microscope but a detailed structure of a microscope can be viewed by an electron microscope mainly a transmission electron microscope.

The transmission electron microscope studies the internals structure of the cell by creating the 2D images by passing the beam of electrons through the specimen.

Thus, a transmission electron microscope is the correct answer.
