Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.
Explanation:
Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc
From the examples given, the cells of multicellular organisms are specialized in function in that:
- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces
On the other hand, unicellular organisms possess just one cell that do all the functions.
Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
Toxicology is the study of toxin effects on human health. The individuals or professionals who carry out toxicology are called toxicologists. In toxicity testing, the dose of a chemical above which there is a measurable decline in the health of the organism being tested is referred to as the toxicity threshold. After identifying the effects and the toxins in the body of an organisms toxicologists device ways of removing or neutralizing the toxin so as to avoid any damaging effects to the body tissues.
General plant life cycle is represented by the diagram in Figure below. From the figure, you can see that the diploid sporophyte has a structure called a sporangium (plural, sporangia) that undergoes meiosis to form haploid spores. A spore develops into a haploid gametophyte.
Answer is. gymnosperm
Answer: Tap water contains added minerals, including calcium, magnesium, and potassium. Hard tap water has higher mineral contents, which some consider more healthful. However, minerals in hard water form deposits that can corrode pipes or restrict the flow.Apr 9, 2019
Explanation:
Answer:
Option C, Bio magnification
Explanation:
In a food chain or energy pyramid, the amount of energy transferred at each succeeding trophic level reduces as compared to the previous trophic level. However, in case of toxic chemicals this flow of energy or food reverses and the amount of toxic chemical increases at each succeeding trophic level as compared to the previous trophic level. This mechanism of accumulation of toxic chemicals at higher trophic levels is known as bio magnification.
Hence, option C is correct
