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.

Answers

The missing part of the question is as follows:

Position    Time (seconds)

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.

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?

Answers

Answer:

Longshore current.

Explanation:

A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.

The energy released by the wave at shore produces a current which is referred to as a longshore current.

Answer:

It would be Longshore Current

Compare and contrast a few aspects of animal and plant cells. You can focus on intra- and extracellular structures they share or don't share, but also be sure to describe processes they both utilize or don't both utilize. Some things to consider: How they obtain 'food' (what is their organic carbon source?) What structures do they share that prokaryotes lack? What do they share that all living cells also share? Do they use CO2, and/or O2 in any processes?

Answers

Answer and explanation:

Although they share some similarities because they are both eukaryotes, plant cells and animal cells are quite different from each other, which is logical since they have distinct lives.

For example, animal cells and plant cells both have a cell membrane, but only the plant cells have a cell wall - which is thick and resistant, and this makes sense because they are more exposed to mechanical and osmotic stress.

Since animals can move towards sources of water but plants cannot, there's also a way in which plants store water in the cells: vacuoles. Animal cells have vacuoles as well although they are much smaller than the single huge vacuole that plant cells have.

All living organisms need the energy to sustain different cellular processes. The organelle in charge of the chemical reactions behind the obtention of energy is the mitochondria, which is present in all cells, but the mitochondrion needs a specific substrate: glucose. Glucose is obtained in diverse ways: animals move and find food that contains glucose in it, while plants produce their own glucose with a specific process called photosynthesis, for which they need an organelle called chloroplast, which animals do not have. In order to transform the glucose into energy, the mitochondria end up generating CO2, which animals expel from their bodies by exhaling. This CO2, now in the air, is used by plant cells as a substrate in photosynthesis (which needs sunlight as well) to produce glucose and also O2, that will be inhaled by animals and used by their tissues.

All living organisms have one thing in common: they possess DNA. DNA contains all of the genetic information of an organism, and it is present in almost every cell of that organism -if it happens to be a multicellular being-. While prokaryotes have their DNA condensed into a single circular chromosome, eukaryotes like plants and animals, have their DNA form many linear chromosomes (quantity varies according to the species) and these chromosomes are inside a very specialized organelle: the nucleus, which prokaryotes do not have.

Answers

Answer:

C. Net Primary productivity

Explanation:

In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.

The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R

Where, R = energy lost via respiration.

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. Select one location to collect water samples in the pond. Collect a 5-mL water sample at 8 am for two days. Measure the amount of pesticide present in each sample using the same measurement tools. After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not reliable? The pesticide measurements were the dependent variable. The samples were collected at different times. The samples were only collected for two days. The time of sample collection was not an independent variable.

Answers

Answer:

The pesticide measurements were the dependent variable

Explanation:

According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:

- Select one location to collect water samples in the pond.

- Collect a 5-mL water sample at 8 am for two days.

- Measure the amount of pesticide present in each sample using the same measurement tools

However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.

Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old

Answers

Answer:

The age of the rock is 5 million years

Explanation:

Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16

Number of half-lives undergone by the substance to leave behind 1/16 of the original sample

1/16 = (1/2) * (1/2) * (1/2) *(1/2)

Therefore, the substance have decayed 4 times

One half=life = 1.25 million years

Four half-lives = 4 * 1.25 million years = 5 million years

Therefore, the age of the rock is 5 million years
