Answer:
<u>prokaryotes</u>
Explanation:
The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as <u><em>prokaryotes</em></u>, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.

The viscosity of water is the thickness of water (it might also be considered the stickiness when talking about other fluids). Water has many properties, and the viscosity of water influences in many of them. We can take the surface tension of a liquid as an example. The more viscous a substance is, higher will the surface tension be and vice versa since there will be a higher and lower attraction between molecules respectively.
→ The surface tension of water is something really important since it contributes in many ways to the environment and if you think about it, if the water was a little less viscous, there wouldn't be water since the viscosity of water makes it resistant to evaporation to a certain degree.

Hydrosphere
Explanation:
- The dolphin swims in the hydrosphere.
- The hydropshere is the region occupied by water on the earth surface.
- They are the oceans, lakes, rivers, glaciers e.t.c
- The hydrosphere makes up 70% the total surface area on earth.
- Ocean occupies a whooping 95% of all.
- The hydrosphere is able to support aquatic life and this is why the dolphin with its streamlined body swims in this sphere.

Answer:
Orthocenter of a Triangle
The orthocenter of a triangle is the point where the perpendicular drawn from the vertices to the opposite sides of the triangle intersect each other.
• For an acute angle triangle, the orthocenter lies inside the triangle.
• For the obtuse angle triangle, the orthocenter lies outside the triangle.
• For a right triangle, the orthocenter lies on the vertex of the right angle.
Answer:
D.
Explanation:
•Specific enzymes catalyze each cellular reaction in cellular respiration. The main role of enzymes during the respiration reaction is to assist in transferring electrons from one molecule to another.
•The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.
ENZYMES ARE REQUIRED FOR MOST OF THE CHEMICAL REACTIONS THAT OCCUR IN ORGANISMS
