Answer:
vertebrate, animals with a backbone, and invertebrate, animals without a backbone
Explanation:
A. worm - no because a worm has no back bone
B- Chimpanzee- Yes because they have a backbone
C. Bacterium- no because it is a bacteria
D. Grass- no because no backbone
so ur answer is b
The population of rabbits on the volcanic island in big portion will dye out, some as a direct consequence from the volcanic eruption, and some because of the lack of food resources. Because the food will be much more scarce, the rabbits will become much smaller, thus needing less food, and also the reproduction process will be much slower and delayed, and as the island recovers from the eruption, the small remaining population of rabbits will start adapting on the new food sources. Once the rabbits are adapted to the new food resources their population will start rising again.
The UV rays cause sun spots due to reaction from the radiation.
The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.
<h3>
What is antibiotic?</h3>
- Antibiotics from the key class of glycopeptides can stop this process.
- Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.
- Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.
- The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.
- Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
- The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.
