Bacteria are unicellular microorganisms that can be found everywhere in the environment. Viruses are microorganisms that can only reproduce within the cells of a host organism.
The differences between viruses and bacteria include;
- Viruses do not have any cell and are considered between living and non-living things, while bacteria have one cell (Unicellular) and are living organisms.
- Viruses are smaller in size (20-400 nm) when compared with bacteria (1000 nm).
- Viruses do not have a cell wall but a protein coat is present, while bacteria have a cell wall that is composed of peptidoglycan.
- Viruses require a living cell to reproduce, while bacteria can reproduce by itself.
- The DNA or RNA of viruses is enclosed inside a coat of protein, while that of bacteria floats freely in the cytoplasm within the cell.
Answer:
B
Explanation:
Chemoreception is a physiological process where an organism reacts to a chemical stimulus in their environment.
Pheremones are chemical substances that organisms release into their environments as a form of communication.
Pheremones bind to chemoreceptors which causes a response once the nervous system of the bee has analyzed and identified the chemical substance. The bee can then react with further communication.
Mitosis occurs in the nucleus and forms 2 identical cells; it is a continuous process, but can be subdivided into 4 phases: prophase, metaphase, anaphase, and telophase; the resulting cells are exact duplicates (clones) of the parent cell. All DNA is double stranded but if it’s meant a single molecule of DNA, it happens in metaphase. Each chromosome makes a copy of itself during DNA synthesis wherein the original chromosome and its copy are joined together. This complete structure is called a chromosome. The two parts (original chromosome and its copy) are called chromatids. At metaphase the two chromatids begin to separate. Each chromatid, once separated, is renamed a chromosome and consists of single DNA molecule.
Answer:
sprint runners rely on lactic acid fermentation as there main source of energy,printing takes a lot of effort and a lot of big movements and a lot energy on demand . cellular respiration makes ATP at a slower rate than lactic fermentation therefore it is anaerobic
Explanation:
the sprinter uses ATP already in muscles as well as ATP produced by lactic acid fermentation. A long-distance runner gets its ATP solely off of cellular respiration
hope this helps
The answer would most likely be D) W, V, Y, Z, X.
