Answer: A and D

Explanation: Sclerenchyma cells are thick cells that provide support in plants. They have thick cell walls lined with lignin. They possess extremely thick cell walls which gives rigidity and support to the plant body. Their main and primary function is to give support and structure to the plant.

Sclerenchyma cells don't have protoplast that mean the cells are dead at maturity.

What evidence must be considered when determining whether or not a trait is an adaptation? (Site 1)
Alexeev081 [22]
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation. The next generation will have the things they will need to survive and the longer the generation goes the more fetchers they will have.

Why is cellular respiration important? Multiple Choice It produces oxygen gas, which is essential to cell functions. It breaks d
trapecia [35]

Answer: (c) It generates ATP, which cells can use to do work.

(d) It generates chemical gradients, which have potential energy.

Explanation:

The overall process of Cellular respiration is the aerobic break down of organic compounds (food) with the release of CO2, water and energy in form of ATP which drives most cellular work.

Organic compound + oxygen --------> carbon dioxide + water + energy (ATP + heat)

In cellular respiration during the break down of food in glycolysis and the citric acid cycle, chemical energy (NADH and FADH) are extracted from each cellular process and transported to the electron transport chain built in the inner mitochondrial membrane. The chemical energy harvested from food is transformed into a proton-motive force, a gradient of H+ across the membrane. When this H+ election fall from their gradient via ATP synthase, Chemiosmosis couples this proton motive force to phosphorylate ADP to form ATP.
