That'd be the cell wall and a permanent vacuole. You could also put chloroplasts :)
<span>The option that best explains why ecosystems need a continual influx of new energy is C. energy flows through an ecosystem and cannot be recycled. Given that it cannot be recycled, and it comes and goes, ecosystems need new energy to replace the old one they may have lost over time. Other answers don't really make much sense and don't have a lot to do with energy/</span>
Answer:
Atoms of all elements—except for most atoms of hydrogen—have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge—they are electrically neutral
Answer:
B) Feedback inhibition
Explanation:
Feedback inhibition is a situation in which the end product of a reaction controls the action of the enzyme that helped produce it. In this process the end products formed at the end of a sequence of reactions participate in inhibiting the activity of the enzymes that helped synthesis the end product. Some examples of products that are used in feedback inhibition are CTP, citrate and Isoleucine. While negative feedback is used in the context of inhibition, negative feedback may also be used for promoting a certain process.
Therefore, when the end product of a pathway inhibits catalysis of the first step of that pathway, this phenomenon is called Feedback inhibition.
Answer:

Explanation:
autosomal recessive means that both copies of the "no tail" allele must be inherited in order to produce a dog with no tail, therefore the answer is both parents
