<h3><u>Answer;</u></h3>
Efficiency = 61.54%
<h3><u>Explanation</u>;</h3>
Efficiency is given by the Formula;
Efficiency = work output/work input × 100%
Work input = Input force × distance moved by the input force
= 13 N × 0,25
= 3.25 Joules
Work output or work done by the screwdriver is 2 Joules
Therefore;
Efficiency = 2/3.25 ×100%
<u>= 61.54%</u>
Answer:
The stomata open to allow carbon dioxide to enter the leaves.
Explanation:
Higher plants are made up of two major system parts namely: shoot system and root system. The shoot system constitutes every part of the plant above the ground i.e leaves, fruits, stem etc. while the root system constitutes the part below ground i.e the roots. The shoot system and root system, however, interacts in several ways to ensure that the plant functions optimally. The ways they interact include:
- The roots (root system) absorb water from the soil, which is transported upwards to prevent leaves (shoot system) from drying up.
- The phloem, which is a conducting tissue, transports sugars (product of photosynthesis) from the leaves (shoot system) to the root nodules (root system) for storage.
- Nutrients are absorbed from the soil by the roots (root system) and moved to the stems (shoot system).
Note that, although it is true that "stomata in the leaves open to allow carbon dioxide to enter the leaves", there is no connection between the shoot and root system.
If you add the amount of protons with the amount of neutrons, you get the atomic mass. Sodium has 11 protons, and 12 neutrons. 11+12=23
<span>All things that are found within the Earth are one way or another, composed of carbon. Carbon is very abundant within metals that are dug from the Earth and they can also be seen making up parts of the human body’s bones to make it light weight. Most scientists believe that throughout the evolution of Earth, carbon has always been present and makes up most of the materials that have existed before. </span>
