Answer:
He is trying to figure out its age.
Explanation:
Rex is finding a strange and very interesting form of a rock. He took a small sample in order to do research. He was trying to measure the amount of radioactive uranium with the radioactive lead.
This way he wanted to show how fast are these objects falling apart depending on the chemical elements they contain.

Flimbsy material will be used for things like clothing shoes hand bags etc.
A recent study concluded that about 90% of all large predatory fish such as tuna have disappeared from the world’s oceans in the past 50 years. Which of these is most likely the direct cause of this loss?
Answer:
New predatory animals .
Explanation:
A valid reason on why a "predatory" animal would disappear or decrease in great numbers is new animals being involved such as animals eating those "predatory" animals or them eating the food source of the original animal . Humans are also a factor but i'm pretty sure they are not hunting them ! I hope this helped
Answer:
non predatory animals
A reason on why a predatory"animal would disappear or decrease in great numbers is new animals being involved such as animals eating thosepredator animals or them eating the food source of the original animal . Humans are also a factor but i'm pretty sure they are not hunting them. Humans use them eat them bad things throw stuff on the lake and it illls them it sad
Explanation:
Please respond on how stress full finals week is
Answer:
Middle school you should be fine just wait till high school lol
Explanation:
Finals week in college is an incredibly stressful period due to multiple exams, projects, and assignments requiring completion. Effective stress management includes preparation, self-care, reducing other commitments, and incorporating physical activity. Recognizing stress symptoms and maintaining a positive outlook are also key strategies.
Explanation:The stress of finals week is a significant challenge for many college students, characterized by a condensed period of high-stakes exams, presentations, and project deadlines. The key to managing this stress effectively lies in preparation and self-care. Having a plan for handling such periods can immensely reduce stress levels. This includes reducing other commitments, ensuring time is set aside for relaxing activities, and adopting a positive attitude towards school and life. Moreover, incorporating physical activity into your routine can be a powerful stress reliever, helping to clear the mind and boost mood. Stress management strategies, such as exercising, spending time with friends, or scheduling downtime, are crucial in navigating finals week successfully.
It's also essential to recognize the symptoms of stress, which can manifest physically, emotionally, and behaviorally. Acknowledging these signs early and taking proactive steps to mitigate them can prevent stress from overwhelming you. Lastly, remember the importance of thinking positively and finding joy in other aspects of life, which can serve as an antidote to the pressures of academic demands.
a house burns down. on the house across the street, all of the vinyl siding is twisted and warped by heat. the heat was transferred across the street by
Answer:
The heat was transferred by radiation
The heat from the burning house was transferred to the vinyl siding of the house across the street by radiation, which occurs in the form of infrared waves capable of traveling through a vacuum.
Explanation:The heat from the burning house was transferred across the street to the vinyl siding of the opposing house primarily through radiation. In physics, heat transfer by radiation occurs without the need for a medium, such as air or water, to carry the energy. Instead, heat is radiated in the form of infrared waves which can travel through a vacuum. This is similar to how the heat from the sun reaches Earth. When these waves make contact with the vinyl siding, they cause the molecules within it to vibrate more vigorously, which increases the temperature and leads to the melting and warping of the material.
The student describes her research project as one experiment. Is this an accurate description?
A. Yes, because the student was studying the factors that affect plant growth in all three pots.
B. Yes, because the student was studying all three plants at the same time.
C. No; the student is performing two different experiments on the same dependent variable simultaneously using the same control but two different independent variables.
D. No; the student is performing three different experiments on the same dependent variable simultaneously using three different independent variables.
The student's research project is not accurately described as one experiment due to the use of two different independent variables simultaneously; hence, it comprises two experiments. An experiment should test the effect of one independent variable on a dependent variable while controlling for all other potential variables that might affect it.
Explanation:The description of the student's research project as one experiment is not entirely accurate. Considering that an experiment generally tests how one variable (the independent variable) affects another (the dependent variable), and in this scenario, the student is using two different independent variables (detergent presence and sunlight exposure), it is more appropriate to describe the setup as two different experiments being conducted simultaneously. The correct option in relation to the student's description would be C, as the student is using the same control (pots without detergent) but two different independent variables affecting the dependent variable (plant growth).
To control an experiment effectively, factors such as the amount of water, type of soil, and environmental conditions like temperature should be constant, except for the independent variable being tested. If the student intended to study the effect of detergent in the soil on plant growth, then having one group in the sun and the other in the shade introduces an additional independent variable – the amount of sunlight – which could confound the results. Therefore, a better experimental design would involve all pots receiving the same light exposure, with only the presence of detergent being different between the control and the experimental groups.
In Gary's experiment, factors such as container size and water amount are controlled to ensure that these do not affect the outcome, which in this scenario is likely the amount of sunshine received by plants.
