Answer:
yes
Explanation:
roots that are deep get to more radioactive material underneath the earth
It is correct that the roots that are deep contain a greater amount of radioactive substances.
What are radioactive substances?Radioactive substances are atoms that naturally decay. They have the ability to emit alpha particles, beta particles, and gamma radiation.
Because they cannot be turned off like X-ray sources, they are more difficult to control.
Radioactive substances emit three types of dangerous radiation: alpha particles, beta particles, and gamma rays.
A substance is said to be radioactive if it contains unstable nuclei and can naturally release energy by shedding high-speed charged particles in an attempt to achieve a stable state.
However apart from the heat produced by the planet's establishment, radioactive potassium, uranium, as well as thorium are presumed to be the three principal sources of heat in the Earth's interior.
Thus, it can be concluded that the deeper roots will encounter more radioactive substances.

List 3 differences between the cat skeleton and the human skeleton; include why the girdles are different. Connect how the differences between the skeletons will cause slight differences in how the muscle are structured.
Answer:
-Humans have 206 bones, while the average cat has about 244 bones.
-Cats have more bones in their spine than humans, to help with their movement
-The human skeleton is 20 to 25 times larger than a domestic cat
-The girdles are different because cats were made to walk on all fours so their structure has to be built differently than humans so they are able to have a range of motion.
-The difference in skeletons causes slight difference in how the muscles are structured because certain muscles are going to need to be stronger, so their will be a difference in muscle shape and size, even though they will carry out the same function.

Explanation:
Water, while beaker b has 50 ml of water. B. State the beaker which is going to require more time to reach room temperature, explain your answer
Answer:
The beaker has more water.
Explanation:
The beaker which has more water takes more time to reach the room temperature because it has more surface area than other one. If a body has less surface area then it will lose heat energy quickly and to reach its room temperature as compared to the body that has more surface area. Heat transfer depends on the materials in which it is placed and the surrounding environment. In some materials conduction of heat occurs quickly as compared to other materials.

Answer the following questions:
1.2.1 What problem did the paramedics encounter at the accident scene?
Answer: Paramedics are the medical professionals which perform multitasking in providing medical aid to the patients in the field as well as in the hospital.
Explanation:
Problems encountered by the paramedic at the accidental scene:
1. Major problem is the collection of the blood and other bodily fluids for examination as it is contaminated over spilling on the road.
2. Stabilizing and uplifting of the patient found on accident and curating them to ambulance is a labor consuming task.
3. Some body parts are severely damaged in accidents some of which includes those parts which covers the vital organs like ribs, spinal cord, skull, and pelvis so stabilizing those parts is a risky task for paramedics and can even kill the patient.

Which of the following is the best definition of Newton's theory of universal gravitation?
Every object is pulled downward with a force that increases as the height from which an object is dropped increases.
Every object is attracted to the Earth with a force that increases with increasing mass and distance.
Every object attracts every other object in the universe, with a force that increases as the objects' masses decrease and the distance between them increases.
Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
the answer would be D!;
every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
The definition of Newton's theory of universal gravitation is : ( D )
Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
Newton's theory of universal gravitation states that "every object attracts every other object in the universe with an attracting force that is proportional to the product of their masses and is inversely proportional to the square of their distances "
Therefore based on the Newton's theory of universal gravitation the best definition from the options given above is Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
Hence we can conclude that Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.

When an object is already in motion, why is energy required to stop it
When an object is already in motion then we require force to stop it because due to inertia , a body tends to remain in the state of motion unless an external force acts on it .This is in accordance with Newton's first law of motion or law of inertia of motion.
What is inertia ?Inertia is the tendency of a body to remain the way it is. It opposes any changes to its state of rest or motion.
The more is the mass of the body , the greater will be the inertia.
What is external force?External force is the force applied by external agents on the body.

given?
Answer:
To be sure about the cause of the pain.
Explanation:
The nurse must ensures the presence of bacteria or microbes before the antibiotics are given because the antibiotic is used for the killing of these microbes such as bacteria. endocarditis happens when the bacteria or fungi enters to the heart through blood streams and cause problems there so for removing this infection we must use antibiotic that kills this microorganisms so the nurse has to make sure that the symptoms is due to microbes or not before the use of antibiotic to avoid any consequences.

Answer:
sex-linked and recessive
Explanation:
A pedigree chart is a genetic representation that exhibits the phenotypes and genotypes for a genetically inherited trait (usually a disease or condition) in a family tree. In this case, the trait in the pedigree is recessive and linked to sex (X chromosome-linked) because it can occur only in males who receive the X chromosome for this condition from their mothers, while females can be carriers that don't have the disorder but can pass it on to offspring.

The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about
Answer:
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
Explanation
Energy can be calculated by the equation
Q = m x Cp x delta T
where
m = mass = 0.5 kg
Cp = specific heat of water = 4184 J
Delta T = 12 degrees
Multiplying all
Q = 0.5 x 4184 x 12 = 25104 Joules
Converting it to Calories
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
