The correct option is A.
In the question given above, we are told that the number of trees in the ecosystem is 1,000,000; this figure far outnumber that of all the other organisms in the ecosystem. The plants are the producers in any ecosystem and they serve as sources of food for all other organisms in an ecosystem. Based on the number of trees present in this ecosystem, the pyramid of number and the pyramid of biomass will be upright, this is bcause the number of producers far outnumber the number of the consumers. A pyramid of number or a pyramid of biomass is said to be inverted if the number of producers is less than that of the consumers.
BRYOPHYTA is the division that classifies green moss growing on a stone building.
Bryophytes are primitive types of plants that do not have a well diffrentiated plant body and vascular system. It is also called as amphibians of plant kingdom because these can grow in water as well as on land.
The part of the eye that allows for varying amounts of light onto the retina is the Iris. <- Answer
Meiosis is a type of cell division in which the parent cell divides into four haploid daughter cells. It takes place in the gametes cells. The process takes place in two stages; meiosis 1 and meiosis II. In this case, During anaphase I of meiosis I, the homologous chromosomes separate and head towards the opposite poles of the cell. Therefore, i believe the answer is Anaphase 1
Answer:
d. cooking contaminated food to kill the bacteria will prevent transmission of the disease
Explanation:
Staphylococcus is an opportunistic pathogen that normally inhabits our skin and respiratory tract. When this bacteria grows in food it produces different enterotoxins, which are stable at high temperatures. That is why if a food is contaminated with this bacterium, it is possible that it already contains enterotoxin and when it is reheated or cooked, even though the bacteria is killed, the toxin will remain active and will generate the disease.
