Answer: Their diet consists of small shrimp and crustaceans, including larvae. As they grow older, they graduate to fish, crabs, and other mollusks.
Explanation:
Answer:
The answer would be A. Increase
1. Answer: A
Explanation: For a cell to form proteins, the specific types of proteins are coded for by the genes in DNA (found in the chromosomes of the nucleus). To produce proteins, the genes are first transcribed by RNA polymerase to form messenger-RNA. The mRNA is then translated into proteins by ribosomes in the cytoplasm of the cell.
2. Answer: B
Explanation: Translation of genes into proteins is dependent on the sequence of nucleotides. They are translated in sequences of 3 nucleotides known as codons. Therefore adding a nucleotide on a piece of DNA causes what is referred to as a frame-shift mutation. The 3 sequences (of codons) is interrupted and shifted by one nucleotide. Therefore, the codons change and the amino acids translated will also change.
3. Answer: A
Expanation: Producers are significant in a food chain because they incorporate the energy of the sun into the food chain. This is why they are at the base of the food chain and have the largest biomass. They are consumed by primary consumers which are consumed by secondary consumers which are consumed by tertiary consumers and so on.
4. Answer: D
Explanation: Plants are consumed by herbivores. Therefore, a decrease in plant population due to drought was resulted to decrease in herbivore population. This is due to stiff competition by the herbivores for the scarce plant population. Carnivores consume herbivores. Due to a decrease in the herbivore population, then the carnivore population would also decrease.
5. Answer: A
Explanation: Burning of fossil fuels emits carbon dioxide gas which is a greenhouse gas. Greenhouse gas traps infrared wavelength of lights hence warming up the atmosphere, causing global warming. Reduction in use of fossil fuels will hence alleviate an increase in global temperature hence protect coral in the oceans from bleaching.
A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".
<u>Option: C</u>
<u>Explanation:</u>
Unlike constant reinforcement, partial reinforcement is only strengthened during certain times or time ratios, rather than emphasizing the action every single time. This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time. Thus here a batsman donot plan intentionally to make a century in every cricket match, but it goes random. Although when they need to score high on pressure, they force themselves to stretch as much possible which is not general.
It is the third option
Carbon dioxide (CO2) + Water (H20) produces Glucose (C6H12O6) and Oxygen (O2)
