It is possible to measure how acceleration changes with mass by throwing objects with different mass from the same height and measuring the acceleration.
What are the important factors for the experiment?This experiment requires you to measure how acceleration changes if the mass changes. This implies you need to consider the following factors:
Acceleration: This factor is the one you will measure in your experiment.
Mass: This factor is the one you will need to control, this implies using objects from different masses and comparing if mas has any effect on acceleration.
Other: Net force, wind, etc. are other factors that need to be constant to prevent them affect the results.
Steps for the experiment:
Choose a specific heigh: One of the ways of measuring acceleration is to throw objects and determine the acceleration as they fall, so the first step will be to establish a height.
Throw different objects with different masses: You can begin with light objects and move into heavier objects.
Measure acceleration: Every time you throw an object, measure acceleration using the formula A = change in velocity/ time.

The correct answer is "Two identical DNA molecules are made that contain one original strand and one paired strand."
Explanation:
The word "conserve" refers to the action of preserving an element. Moreover, the prefix "semi" refers to partial. In this context, DNA replication can be considered as a semi conservative process because the original DNA is partially preserved. This is explained in "Each of the two daughter molecules made during replication contain one strand from the parent molecule and one new strand" because this excerpt shows how in the process each of the cells resulting has at least 50% of the DNA of the original cell. This implies replication does not lead to a completely new cell as part of the genetic material is kept. According to this, this process can be considered as semiconservative because "Two identical DNA molecules are made that contain one original strand and one paired strand."
why are there so many stages in meiosis?
Answer:
In many ways meiosis is a lot like mitosis since cell division occurs twice during meiosis one starting cell can produce four gametes ( egg or sperm ) in each round of division cells go though four stages prophase, metaphase anaphase, and telophase
Explanation:
A farmer has been trying to increase his crop yield for the last 10 years by
adding about 25% more fertilizer to his crops than he needs. What will most
likely result from this action?
Select one:
a. Increased crop yields.
b. Air pollution from the excess fertilizers
c. Soil degradation form the excess fertilizers
d. The additional fertilizer will have little to no impact.
Answer:
The correct answer is - b. Air pollution from the excess fertilizers
Explanation:
In long term using excess amount of fertilizer than requirement will lead to several condition such a soil acidity, soil degradation, soil leacing, eutrophication of waterways and many but more improtant is green house gases and air pollution.
Using the excess amount of fertilizer does not help in increasing crop yield but gives negative impact. Using fertilizer more than requirement wil lead to release of toxic and harmful gases in atomosphere and fuming.

Answer:
7683.2 Joules
Explanation:
We can calculate potential energy using the equation that is used to calculate the work done by a conservative force, in this case, gravity.
U(x)gravity = mgy
U represents potential energy, m is mass, g is gravity, and y is the height.
U(x) = (80 kg)(9.8 m/s^2)(9.8m)
Potential Energy = 7683.2 Joules

Answer:A adenine could hydrogen-bond with thymine and guanine could hydrogen bond with cytosine to hold the helix together
Explanation:
The double helix model of DNA explained Chargaff's rules because adenine could hydrogen-bond with thymine and guanine could hydrogen-bond with cytosine to hold the helix together. The correct option is A.
What is Chargaff's rule?According to Chargaff's criteria, guanine and cytosine should be equal in amount in the DNA of every species and organism, and adenine and thymine should be equal in amount.
Additionally, the purine and pyrimidine bases should be in a 1:1 stoichiometric ratio.
The ratio of the several nitrogenous bases present inside the DNA molecule is described. It assists in figuring out the makeup and structure of DNA in various species.
Because adenine could hydrogen bond with thymine and guanine could hydrogen bond with cytosine to maintain the helix together, the double helix model of DNA provided an explanation for Chargaff's rules.
Thus, the correct option is A.

Precipitation falls to the ground and eventually ends up in the ocean. Which of the following is the most direct way for the water to get from the soil to the ocean? A. By way of a recharge zone with a low percolation rate B. By way of a closed watershed C. By way of an open watershed D. By way of thermohaline circulation within an aquifer
Answer: D. By way of thermohaline circulation within an aquifer
Explanation: The most direct way for the water to get from the soil to the ocean is by way of a recharge zone with a low percolation rate. Human activity in the recharge zone can limit the amount water that reaches the aquifer.

if you do not contact your loan servicer to select another option, your Federal student loans will default to standard repayment, which has a term of
Answer: 10 years
Explanation:
When the student is not able to pay the loan on regular basis then the repayment plan is available that is called standard repayment plan. It is a kind of default plan for all and most kind of student loans. In this the monthly payment is broken down of an amount of $50 which is the minimum amount for loan pay for the duration of maximum 10 years. This payment plan helps to lower down the interest money on the payments.
Describe endocytosis, phagocytosis, pinocytosis, and exocytosis.
Answer:
Endocytosis: Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle.
Phagocytosis: Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles.
Pinocytosis: Pinocytosis, a process by which liquid droplets are ingested by living cells.
Exocytosis: Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport.

explain how water properties help get water from the roots of plants to leaves
Answer:
In order for water to move through the plant from the soil to the air (a process called transpiration), soil must be > root > stem > leaf > atmosphere. ... Because of this difference in water potential, water will move from the soil into a plant's root cells via the process of osmosis.

Morphine 4mg IV push is ordered. The vial states 10mg/mL. How many mL will you give?
Answer:
If a vial of morphine has 10 mg/mL, and a dose of 4 mg is required to be administered intravenously, 04 mL must be administered to fulfill the indication.
Explanation:
Morphine is a drug, an opioid derivative, with a potent analgesic and sedative effect. Its use is intended for acute or chronic severe pain, mainly related to cardiovascular disease, cancer or severe trauma.
One vial of morphine vial has a concentration of 10 mg/mL, so if 4 mg is required, a simple calculation must be made:
Morphine: 10 mg ------------ 1 mL
Dose: 4 mg ------------ X
X = (4 x 1)/ 10
X = 4/10
X = 0.4 mL
To administer 4 mg of intravenous morphine, 0.4 mL of the injection should be used.

Desert plants and animals are adapted to the lack of what and high
Answer:
lack of water and high concentration of heat and dryness
Explanation:
Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.
