Answer: a trillion cells
Explanation:
Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms
The beetles that died were unable to avoid or detoxify the chemical and were thus killed by nerve poison insecticides.
- Chemicals called insecticides are used to kill insects or stop them from acting in an unwanted or destructive way. Their structure and mechanism of operation are used to categorize them.
- Most insecticides function by interfering with the insect's nervous system. The herbicide prevents neurotransmitters in synapses from transmitting information.
- Acetylcholine is the name of the substance that the body produces and uses to transmit information through synapses. Muscles can relax because of an enzyme called cholinesterase that binds to acetylcholine.
- Through the synapses, acetylcholine communicates with the muscles. The cholinesterase is impacted when a pesticide is administered at a deadly dose for a specific body, preventing it from binding with the acetylcholine.
- The muscles become overstimulated as a result, which will cause paralysis and death.

The question is incomplete as it does not have the options which are:
A.) Presence of genitalia.
B.) Shape of genitalia.
C.) Presence of a scrotum.
D.) Composition of accessory fluids.
Answer:
Option-A
Explanation:
The reproductive system which is the system formed by the organ which is involved in the reproduction in an organism. These reproductive organs are known as genitalia. Since reproduction is one of the criteria of the cellular organisms, reproduction is possessed by all the organisms on Earth.
The animals which bear the reproductive structures therefore always show the presence of both internal and external reproduce organs like testes, Vas deferens as internal organs and penis and scrotum as external organs.
Thus, Option-A is correct.
Answer:
comparative anatomy
Explanation:
they both provide evidence for evolution homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor the structures are similar because they evolved to do the same. Not because they were inherited from a common ancestor
Answer:
B. nitrogen-fixing
Explanation:
Nitrogen fixing bacteria are able to change pure nitrogen into ammonia compounds.
Nitrogen fixing bacteria are found in the soil close to the root of leguminous plants. They are get their own nutrition by chemosynthesis.
- They take nitrogen from the atmosphere in form of nitrogen gas.
- The nitrogen gas is converted into fixed nitrogen compounds such ammonia.
