Which process occurred when water droplets formed on the grass
Answer:
condensation
Explanation:
because water is collected as droplets on a cold surface when humid air gets in contact with it
Condensation is the process occurred when water droplets formed on the grass because water is collected as droplets on a cold surface when humid air gets in contact with it.
What is condensation?The water droplets forming on inside is condensation.The transformation of airborne water vapor into liquid water is known as the condensation of water. It takes place when water transitions from a gaseous state to a liquid or crystallized state.
When the air is cooled below the dew point, the excess water vapor condenses onto surfaces in the form of water droplets. This is why we may notice water droplets forming on the outside of a cold glass of water on a hot day, or on the inside of a window on a cold day.
At high pressure and low temperature, any gas can condense. As a result, water droplets condense on the interior of a chilly windshield. Water droplets can form inside windows due to a process called condensation.
Therefore, Condensation is the process occurred when water droplets formed on the grass because water is collected as droplets on a cold surface when humid air gets in contact with it.

Describe ways in which a healthy artery differs from an artery affected by coronary heart disease
Answer:
A healthy artery is wider and has no blockages. The lumen (which is the hole in the centre of the artery), is open and clear. This means there is more blood flow. An artery of a person suffering from coronary heart disease is often blocked, usually by a fatty deposit. This means the blood does not flow as well. (See diagram, in which I would draw two arteries, one with a blockage of fatty deposit, one clear and healthy).

Why are most oceanic trenches found in the Pacific Ocean?
Answer:
It's where the subduction zones are.
Explanation:
Subduction zones - when two plates meet and one gives way to the other.
Answer:
Most oceanic trenches found in the Pacific Ocean because it is the largest ocean, therefore it has most most convergent boundaries. Whenever a convergent boundary is formed it creates a trench because the oceanic plates are denser the continental plates so they sink. This is known as subduction.
To test the effectiveness of a new nutrient supplement, one group of identical mice is given the supplement, and the other group is not given anything. Which is the most complete list of the parts of an experiment presented in this scenario? independent variable, dependent variable control group, experimental group, dependent variable independent variable, control group, experimental group control group, experimental group
Answer:
The answer is the second option: Dependent variable, experimental group and control group
Explanation:
Let's list out all possible variables/groups in the option
Independent variable: This is a variable that is intentionally (directly or indirectly) altered by the one doing the experiment but is not affected by any variable/group during the course of the experiment. No Independent variable was mentioned.
Dependent variable: This is a variable that is affected by another variable and is usually the variable been tested during the course of an experiment. The dependent variable here is the effectiveness of a new nutrient supplement.
Experimental group: This is the group that is being treated during the course of an experiment. The experimental group here is the group of identical mice given the supplement.
Control group: This is a reference group that is not given any treatment during the course of an experiment. The control group here is the group of identical mice not given anything.
From the above description, it can be deduced that the parts of the experiment described in the scenario in the question is dependent variable, experimental group and control group.

Finches that eat seeds and plant parts have beaks of the shorter, thicker variety, while finches that eat insects and other small organisms have thin, pointed beaks. 78% of the finches on an island in the Galapagos have beaks that are identical to Finch 1. What conclusion can you reach about the availability of food for the finches on this island?
A)
There is an abundance of insects.
B)
There is an abundance of seeds and nuts.
C)
There is a wide variety of foods for the finches to eat.

2. I Love Popcorn!
Jason wanted to find out how he could increase the number of popcorn kernels that pop when
1
cooked. He hypothesized that more kernels would pop if he used more oil. To test this, he placed
100 kernels of "Pop Rite' popcorn into a popcorn popper that contained different amounts of oil. He
used the following amounts of oil: 5 ml, 10 ml, 20 ml, and 30ml. He used 5 ml of oil as the control.
Header
He conducted the test 3 times for each amount of oil. He then counted the number of kernels that
had popped. Each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes.
Hypothesis: I think the popcorn with the most oil will have the most popped kernels because the hotter
all the oil gets and the more oil there is in it, then the kernels will be able to pop faster. What are the:
Independent Variables:
Dependent Variables:
Controlled Variables:
Answer:
Independent: amounts of oil
Dependent: amounts of popped kernels
Controlled variables: Kernel brand, cooking time, popping time
Explanation:
Independent variables are what are changed in the experiment. The dependent variables depend on the independent so they are what is affected each time. Usually this is what is being tested for. Controlled variables are those that aren't being tested and are kept the same each time to make sure it doesn't change the outcome.

1. Was the restoration project effective? Explain why or why not, supporting your answer with information from your data tables and graphs. 2. Why was counting the number of species in the area important? In your answer, consider the effect a mangrove habitat has on biodiversity. 3. After five years, the average height of each mangrove species was also measured. Did this information help you better evaluate the success of the restoration project, or did it change your mind? Explain your reasoning.
Answer:
1- Yes the restoration was effective because the north beach seeds were replant and in 5 years there was almost 100% regrowth of mangroves. After five years, the average height of each mangrove species was also measured.
2- Yes the counting the number of species in the area was important because it helped figure out how much the storm damaged each beach and it showed how the animals were affected. The effect a mangrove habitat has on biodiversity is by giving animals a home, a place to sleep and shelter.
3- Yes, after five years, the average height of each mangrove species was also measured which helped realize that the restoration project was a success.

(b) Describe how a student could test cow's milk to show whether it contains protein
different types of carbohydrate.
To show that cow milk contains protein and different types of carbohydrate,food tests should be carried out by the student.
Carbohydrates (sugars) are the main sources of food through which the body derives energy from.
The various types of carbohydrate are the simple sugars, complex sugars and starch.
Proteins are the main body-building substances which are necessary for the maintenance of health.
The cow milk contains proteins and a type of carbohydrate called lactose which is an example of complex sugar.
To test for protein in milk, xanthoproteic reaction test should be carried out by the student. The procedure includes:
To the milk solution add a few drops of concentrated nitric acidA white precipitate forms, which turns yellow on heating.Cool the contents and add a few drops of ammonia solution.The colour of the precipitate deepens to yellow indicating presence of protein in the cow milk.To test for carbohydrate in milk, a test for complex sugar should be carried out by the student. The procedure includes:
Add milk solution and hydrochloric acid into a test tube. Place the test tube inside a boiling water-bath.The acid hydrolyses the complex sugar to simple sugars.Fehling's test is then carried out on the simple sugars that are formed which are glucose and galactose.An orange-red precipitate indicates a positive result.Learn more here:
