Energy conservation and efficiency are the major “sources” of energy because these methods make available more energy sources and reduce wastage of it.
<h3>What is energy efficiency and why is it important?</h3>
Energy efficiency refers to using less energy to perform a task. In this method, reduce or eliminate energy wastage. Energy efficiency brings many benefits such as reducing greenhouse gas emissions, reducing demand for energy imports, and reducing our costs on a household and economy.
So we can conclude that energy conservation and efficiency are the major “sources” of energy because these methods make available more energy sources and reduce wastage of it.

The answer to both questions is the same. It’s that the moon is a world in space, just as Earth is. Like Earth, the moon is always half illuminated by the sun; the round globe of the moon has a day side and a night side. From our earthly vantage point, as the moon orbits around Earth, we see varying fractions of its day and night sides.<span> These are the changing phases of the moon. And the moon </span>is<span> in the daytime sky about half the time. It’s just that it’s sometimes it’s so near the sun we don’t notice it. How can you understand moon phases? Here are four things to remember:</span>
Answer:
1. false
2. true
3. true
Explanation:
1. Annuals are the plants that complete their life cycle in one season or one year. These are the herbaceous plants that grow, flower and die in one season. Examples of annuals are geranium, marigold, etc.
2. In a flower, the whorl of petals is called corolla while the whorl of the sepal is known as calyx. In flowers, calyx and corolla together make perianth. The calyx is outer to corolla in a perianth.
3. The fruit is a matured and ripened ovary that provides protection to the seeds present in it. Fruits are formed after fertilization and may contain one or more seeds. Tomatoes are the simple berry fruits while cucumber is pepo, the modified berries. Broccoli is the flower head while celery is the edible leaf.
<h3><u>Answer;</u></h3>
Whereas segregational petites exhibited Mendelian inheritance, both neutral and suppressive petites followed non-Mendelian patterns that were consistent with the involvement of an extranuclear agent
<h3><u>Explanation</u>;</h3>
- Mutations that yield defective mitochondria are expected to make cells grow much more slowly. These mutants were called petites to describe their small colonies compared to large wild type colonies.
- Petite mutants could not grow when cells had an energy source requiring only metabolic activity of mitochondria - needed sugar as well which is part of glycolytic pathway.
- Segregational petites, segregated in mendelian manner during meiosis. mutations cause defects in genes in cell nucleus encode proteins necessary for mitochondrial function.
- Vegetative petite mutants do not segregate in mendelian manner; two types: neutral and suppressive; carry mutations in mitochondrial genome itself; when two yeast cells are mated, daughter cells inherit mitochondria from both parents.
- Neutral petites lack most of their mitochondrial DNA; when mated with wildtype, the wildtype give their mitochondria so all cells display a normal phenotype.
