Answer:
+1, -1.
Explanation:
Ions may be defined as the molecules that contains charge in their structure. Ions that carry positive change is known as cations and ions that carry negative charge are known as anions.
The velency may be defined as the number of electrons present in the outermost shell. The +1 has the highest tendency to form cations because a little amount of ionization enthalpy is required to remove the 1 electrons. The -1 has highest tendency to form anion as it has the most negative electron gain enthalpy and can easily gains an electron.
Thus, the answer is +1 and -1.
Answer: it is community
Explanation: got it right I promise
The species of fish in the Monterey Bay aquarium represent the community ecological level.
All of the different species of fish in the Monterey Bay aquarium represent the community ecological level. In ecology, the community level refers to all the organisms of different species that interact with one another in a specific area. The Monterey Bay aquarium contains a diverse community of fish species, each occupying different ecological niches and contributing to the overall functioning of the ecosystem.

Answer:
Option (C).
Explanation:
Sex linked disorder may be defined as the disorders that are caused by the mutation or defects in the sex chromosome. Two main types of sex linked disorder are sex linked recessive and sex linked dominant.
Hemophilia is caused due to the defect in the clotting factor. This is a sex linked recessive disorder that are transferred from female to their sons. The hemophilic father has only one X chromosome and they will transfer this affected X chromosome to their daughters and none of their sons. Since, sons receive Y chromosome from their father.
Thus, the correct answer is option (C).
Answer:
The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.
Explanation:
The doppler effect is a physical phenomenon. This phenomenon allows us to perceive if an object is approaching or moving away through the wave effect that that object produces in relation to an observer. This is because when a wave is propagated the speed of that wave depends on the environment in which it is being emitted. For this reason, the speed of this wave will be constant even if the observer moves, but the frequency and movement of this wave varies in relation to the observer's position. In this case, the Doppler effect suggests that the sound waves are relative to the observer. You know if an object is coming in or out of the sound it produces. The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.
