Answer B burning fossil fuels in vehicles, power stations, and factories
Explanation:
The life cycle stages of a plant would be seeds → germination→growth→maturity→pollination→fertilisation→seeds etc etc.
so I would say the life cycle stages not found in animals would be either pollination or germination.
Answer:
D
Explanation:
Control group in an experiment does not receive any treatments. It is used as a benchmark to ensure that there is statistical difference in data between the variables of the control and those with treatments. It also ensures that there are no other overlooked factors that have an influence on the experiment that needed to be considered. Having a control group reduces the chances of erroneous conclusions.
Answer: endoplasmic reticulum
Explanation:
Prokaryotes ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes
Eukaryotes (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes
Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria, and endoplasmic reticulum
Both may contain a cell wall, flagella, ribosomes, DNA and plasma membranes
A pathogen would first try to infect the body and the body tries its best to defend against the pathogen but when it fails you would be infected and fall sick BUT if you are exposed to the same pathogen when you have fully recovered you would have a slightly better immunity against that pathogen since your body had fought it before
