The option with mosses, ferns, conifers, flowering plants is the group of phyla which contains only plants.

Explanation:

Mosses, ferns, conifers, and flowering plants are the four basic groups of the plant kingdom.

Mosses of Bryophyta are primitive non-seeded non-vascular plants which lacks true shoot and root structures.

Ferns of Pteridohyta are vascular plants with a true root and shoot system but without flowers or seeds

Conifers are woody perennial gymnosperms which are cone-bearing vascular and seeded plants.

Flowering plants are angiosperms and fruit bearing and seed producing plants.

The annelids, chordates, cnidarians, mollusks, arthropods, and echinoderms belong to kingdom animalia.

Marysya12 [62]

Answer:

7.5cm

Explanation:

Velocity vs Time Graph:

When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.

Velocity vs time graph:

Is shown in the attached image

A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.

Height of the triangle is the velocity (v) = 0.75m/s

The base of the triangle is the time interval (t) = 0.2sec

Distance travelled = Area of triangle

Distance travelled

= 1/2(V) * t

= 1/2(0.75m/s) * 0.2s

= 0.0075m

=7.5cm

Thus, during one beat blood flows 7.5 cm

ziro4ka [17]

Answer:

Cilia

Explanation:

The respiratory system is the system of organs which allows the inhalation and exhalation of the gases especially oxygen and carbon dioxide. The respiratory system begins from the nose or nasal passage and end at the lungs.

The histology of the respiratory passages reveals that the epithelium layer of these is made of the columnar, cuboidal and the simple squamous epithelium along with ciliated structures. These ciliated structures allow the movement of the mucus secretions and the other cell by whiplash movement.

In the given question, since the epithelium of the person is not able to move the fluid therefore the structure that is involved in the cilia.

Thus, cilia is the correct answer.
