Answer

D. Discarded plastics nets and fishing lines

Explanation

Plastic nets and fishing lines discarded into water bodies are examples of solid waste pollution on water bodies. These items potentially lower the quality of water thus putting the life of marine animals at risk. Other  factors that can harm marine life are oil spillage, runoffs containing farm fertilizers which cause eutrophication, and  untreated sewage released to water bodies.

Assume that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated. Calculate the total pore space and total po
stiks02 [169]

To calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. Therefore, the value of the total pore space and total porosity are 45g and 45% respectively

Given that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated.

The given parameters are;

Volume of soil V = 100cm^{3}

Mass ( Oven dried) M_{1} = 78g

Mass ( Saturated) M_{2} = 123g

In the soil formation, pore space refers to the volume of soil. And to calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. That is,

Total pore space =  M_{2} - M_{1}

Total pore space = 123 - 78

Total pore space = 45g

And total porosity will be the percentage of the ratio of total pore space to the given volume of the soil. That is,

Total porosity = (Total pore space / volume of the soil) x 100

Total porosity = 45/100 x 100

Total porosity = 0.45 x 100

Total porosity = 45%

Therefore, the value of the total pore space and total porosity are 45g and 45% respectively

Did Thomas Jefferson see the Missouri compromise a success
max2010maxim [7]
When Thomas Jefferson referred to the Missouri Compromise he described it as “ fire bell in the night”. This is because he saw it as a pressing matter and he saw this as an emergency since a fire bell at night indicates that there is an emergency.

Dr. Keyes is a veterinarian who believes that people are happier if they own more pets. He hopes
pickupchik [31]

Answer:

False.

Explanation:

The study that Dr. Keyes wants to do is a study that uses two variables (pets and happiness). Dr. Keyes wishes to prove the cause and effect relationship between these two variables that prove that the greater the amount of pets (causes) people have, the greater the happiness of these people (effect). For this reason, we can say that Dr. Keyes is not doing a correlational study.

This is because, although the correlational study wishes to observe the relationship between two variables, this study cannot be applied to cause and effect relationships.
