The BEST example of a point source of water pollution is factory effluent (Option c).
Water pollution refers to the contamination of water with pollutants. These substances (i.e., pollutants) convert water unusable to carry out different activities (e.g., drinking, cleaning, etc).
Water pollutants include, among others, herbicides, food processing waste, volatile compounds, heavy metals, organic pollutant microorganisms (e.g. bacteria, parasites), etc.
Factory effluents are well known to be harmful water pollutants for aquatic ecosystems.
In conclusion, the BEST example of a point source of water pollution is factory effluent (Option c).

Choose ALL that apply for mangroves.
Mangroves have bladders in their leaves to dilute the seawater.
Aerial roots act as support to hold their tops above water.
Mangroves han leaves that contain glands, which expel salty water.
Holes in the central stem take in air for the roots of the mangrove.
Answer:
Aerial roots act as support to hold their tops above water.
Mangroves has leaves that contain glands, which expel salty water.
Explanation:
A mangrove is a shrub that grows in coastal saline or brackish water due to their salt tolerance abilities. Aerial roots act as support to hold the plant in water as well as provide oxygen to the plants. These aerial roots are present outside the water so that to provide oxygen to the plants directly absorb from the atmosphere. Mangroves leaves contain glands, which removes salty water from the body so due to these glands, mangrove is able to grow in saline water.
When a population is is experiencing exponential growth, which of the following is true?
A. Birth and immigration rate is less than death and emigration rate.
B. The population has reached its carrying capacity.
C. Birth and immigration rate is greater than death and emigration rate.
D. Birth and immigration rate is equal to death and emigration rate.
Answer:
A. Birth and immigration rate is greater than death and emigration rate.
Explanation: trust
Birth and immigration rate is greater than death and emigration rate. Therefore, option (C) is correct.
What is exponential growth?Exponential growth is a type of population growth pattern in which a population size increases at an accelerating rate, with each generation or time period adding a larger number of individuals than the one before it. This type of growth results in a population having a higher total number of members than it did in the previous generation.
To put it another way, the rate of population growth picks up steam over the course of time, producing a J-shaped curve when the data is plotted on a graph. This pattern can emerge when there is an abundance of resources available to a population but only a moderate amount of competition for those resources. This results in rapid reproduction and population growth as a result.

These show the 2 alleles of each parent plant crossed with each
other and the resulting 4 possible offspring with T= tall, = short.
TT = dominant tall, 17 = recessive short, Tt = mixed hybrid
TT = dominant tall (genotype tall, phenotype tall)
Tt = mixed hybrid (genotype hybrid, phenotype tall)
tt = recessive short (genotype short, phenotype short)

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.
Answer:
Parasitism
Explanation:
Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.
A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.
What are different types of symbiotic associations?In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.
Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.
In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.
In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.
Hence, the fourth option is the correct answer, which is parasitism.

at what point did the climate began to fluctuate more severely ? (2 points )
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions?
Answer:
These two reactions have different reactants, bonding and catalysts.
Explanation:
The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms. In these two reactions, different types of catalyst are used which helps in speedup the chemical reaction so we can conclude that these two reactions have different reactants, bonding and catalysts in their chemical reaction.
