Donna has observed that her father can control the speed of their grandfather clock by adjusting the

height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when

the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes

for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to

move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.

Donna records her data.

Answer 1

The missing part of the question is as follows:

Position    Time (seconds)

1             23.23

2           21.56

3           20.33

4           19.00

5           18.02

Hypothesis: ____________

Dependent Variable: ____________

Independent Variable: ________________

Constants: __________

Control Group:_________________

Experimental Group: ____________

Answer:

Hypothesis:

if the weight is lowered the pendulum will move faster

Dependent Variable:

Time it takes the pendulum to swing or move

Independent Variable:

the position of the weight

Constants:

same weight and the same number of swings

Control Group:

pendulum at the lowest position

Experimental Group:

different height of pendulums

Explanation:

A hypothesis is a possible explanation for the observation in a given experiment which is "if the weight is lowered the pendulum will move faster" as it states the effect of length of the pendulum on the time it takes to swing.

The dependent variable in an experiment is affected and measured to see the effect which is the time it takes the pendulum to swing or move which is measured here and affected by the independent variable that is the position of the weight.

Constants are the variable that remains constant throughout the experiment that is the same weight and the same number of swings. Control group is the group of subject or condition which minimize the effect of factors or variables except one factor to compare or ensure if the experiment works that are pendulum at the lowest position. The experiment group is the group of a subject that get treatment desired to influence the dependent variable that is the different height of pendulums.

Why does DNA need to be extracted from a cell before it can be analyzed?

Answers

Answer:

to study the genetic causes of disease and for the development of diagnostics and drugs.

Explanation:

It is important to extract DNA from a cell in order to study the genetic causes of disease and for the development of diagnostic and drugs. Scientists will use a cell culture system, which is cells from an organism that have either been made to continuously proliferate (grow) or are cancerous in nature (from cancer).

These cells allow us to continue working on experiments where we can change the conditions to determine various cell functions.

To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.

Dimetrodon fossils:

Because its remains have been discovered in Texas and Oklahoma in the United States, Nova Scotia, Canada, and all throughout Europe, the Dimetrodon is likely to have been well suited to a broad range of environments.

The first fossil was discovered in the nineteenth century, and Edward Drinker Cope named it in 1878.

In a woodland ecosystem, the number of species of microorganisms in the soil that do not
harm plants increases. How does this rise in biodiversity affect the sustainability of the
ecosystem?
A The rise in biodiversity makes the ecosystem less sustainable.
B The rise in biodiversity makes the ecosystem more sustainable.
C The rise in biodiversity does not change the sustainability of the ecosystem.
D The rise in biodiversity makes the ecosystem only temporarily less sustainable.

Answers

Answer:

I think it’s B

Explanation:

Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.

What is the rise in biodiversity in woodland ecosystem?

In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.

Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.

Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.

Therefore, The rise in biodiversity makes the ecosystem more sustainable.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?

Answers

Answer:

S.A for Edmentum and Plato

Like and Rate

In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.
