Hope this helps for number 2 not worried about points
A chemical reaction can be described by discussing the chemical substances at all steps. It is more efficient to use a chemical equation than words, and there are agreed-upon conventions to summarize the reaction, the substances that take part in it, the products, and the amounts
Explanation:
"Function of a reservoir in a nutrient cycle is to meet the deficit which occurs due to imbalance in the rate of influx & efflux. Give an account of energy flow in an ecosystem."
This is a very good question and the answer to it is option A. The common core set of genes is very similar between all organisms.
This is true because several facts, for example, all living beings on earth share the same gene code: DNA, all of them are based on DNA or RNA, which humans have it too. This was explained by Darwin's evolution theory, we are all descendants of just one single species, and because of that, all species have something in common between them.
That's why there's a possibility that a human gene can correct a defective gene in a yeast cell. Although this could really happen, we are not sure about it, it's a possibility, don't always be sure of something in biology, there's always more to understand and to learn.
Answer:
2 protons, 2 electrons, and 1 neutron.
Explanation:
Atoms are made-up of sub particles called protons and neutrons found in the nucleus. The protons are positively charge while the neutrons have no charge. The electrons are found in the shell orbitals and are negatively charged and in constant motion. 2 protons will neutralize the negative charge of the 2 electrons in the outer shell.
