Curious about the World

Algae and Protozoa are two examples of organisms that belong to the same kingdom. Both belong to the kingdom Protista. And since they are from the same kingdom, they are very similar based on some properties that are common between them. They are eukaryotic organisms because they cannot be regarded as an animal, plants, or fungus. Algae are photosynthetic organisms, and as a result, they can produce their own food. Protozoa, on the other hand, are nonphotosynthetic organisms or animal-like protists that feed only on small organisms.

They move only by using pseudopods, cilia, or flagella. Protozoa are shapeless organisms, and they are unicellular organisms, and that's why before you can have a good look at them, you need a microscope. Algae, on the other hand, look like green, and that's why there is the presence of chlorophyll in their cells. They are mostly seen and found floating on water.

Viruses are harmful and are not basic.

Bacteria are living organisms and they are harmless, they cooperate with your bodies most of the time.

Let's see how far my knowledge stretches

The terms zygote and embryo are usually incorrectly used by some people as they think they are just the same. But in reality and by looking up at their meanings in the dictionary, they are two different words. The zygote is the first cell of an organism that is produced from sexual reproduction. Embryo, on the other hand, is the multicellular eukaryote in the early stages of an organism’s development.

In humans, the embryo starts to develop and is present in the womb after eight weeks of fertilization. The word zygote comes from the Greek word zygotes, which means to join or to have been joined while the embryo is from the Latin word embryo, which means that which grows.

Correct answer is option B
If there is a gene alteration causing a plant to be deficient in photorespiration there would be more light induced damage to the cells. This is because photorespiration has photo protective effects, preventing light induced damage, it helps maintain redox balance in cells, and also support plant immune defences.

First, you need to know that photosynthesis and photorespiration is not the same but they work hand in hand. Photorespiration refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced in photosynthesis. It incurs a direct cost of one ATP and one NAD(P)H.

Photorespiration reduces the efficiency of photosynthesis.
In photorespiration RuBisCO enzyme reacts with oxygen while photosynthesis occurs when RuBisCO enzyme reacts with carbon dioxide.

Reproduction is something that is general to living organisms and it is part of many things that classifies a man or an organism to be a living thing. Reproduction can be defined as the biological process in which living things are able to produce a replica of them. In man, you are biologically fit to give birth to a child only when your reproductive organs are matured enough to do so.

The primary reason for reproduction is to ensure a regular sequence of existence of various animal species. Reproduction will prevent certain animal species from going into the extinction. Just imagine a world where the word 'Reproduction' has never been heard, you should expect a total extinction of every living thing. The earth is designed in a way that it ensures the continuous existence of different species in it. Reproduction makes it possible for us to be having a succeeding generation.

Ring worm is a fungus, not a Nematode. So, although the earthworm is not a nematode, neither is ringworm.

Varicella-Zoster virus. This is the virus that causes both chicken pox (varicella) and shingles (herpes zoster). This virus can lie dormant in nerve cells and reactivate without warning, and sometimes occurs after a hematopoietic stem cell transplant. Since it can lie dormant for so long, this is a likely cause of infection a year after the transplant.

The other options are possible infections that could come from a hematopoietic stem cell transplant, but usually not after so long. Pneumocystis carinii, for example, is an opportunistic fungus that infects immunosuppressed patients, such as those with HIV or those who have recently undergone a hematopoietic stem cell transplant. After the space of a year, though, this infection would be much less likely.
