Answer: The law of mass action suggests that the rate of a chemical reaction is directly proportional to the product of the masses of the reactants. In this, each mass is raised to a power, which is equivalent to the coefficient of that reactant in the chemical reaction.
For example- For the chemical reaction-
aA + bB → C + D
Rate of the reaction α [A]ᵃ [b]ᵇ
Rate of the reaction = k [A]ᵃ [b]ᵇ
where, k = rate constant
a+b = order of the reaction.
(1) snake eating a bird
(2) tree absorbing minerals
(3) fungus breaking down wastes
(4) deer eating grass
Answer:
(4) deer eating grass
Explanation:
In ecology, a pattern of feeding exists through which organisms obtain energy by feeding on one another. This pattern is called FOOD CHAIN. Each organism of the food chain are classified into into steps called trophic level based on their feeding behavior.
The first level contains unique set of organisms called AUTOTROPHS, based on their ability to produce their own food. These autotrophs are usually plants in a terrestrial environment. They are called PRIMARY PRODUCERS. They are the lowest level in the food chain.
These producers are eaten by another set of organisms called PRIMARY CONSUMERS. They are dependent on plants for food and energy source, hence, called heterotrophs.
In this question, the grass represents the producer, which will be fed upon by a herbivorous deer (consumer)
Answer;
-a scientific question is a hypothesis. which has to be testable.
Explanation;
-A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A hypothesis is a tentative, testable answer to a scientific question.
-A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e, it can be tested by another individual through an experiment or measurement), leads to a hypothesis that is falsifiable (i.e. it should generate a hypothesis that can be shown to fail), etc.
Answer: B.heat is absorbed
Explanation:
Answer:
B)
Explanation:
Endothermic reation occurs when a chemical absorbs heat.
Three environmental factors that could cause certain neurologist conditions:
- Radiation: This may produce Cancer in the brain, making it spread.
- Genetic Mutation: This has many symptoms, it can cause autism, Down syndrome, strokes etc.)
- A lot of Drugs/Alcohol: This may cause long term diseases, delirium, and dementia.
Is it okay?
Answer:
Three environmental factors can be:
1.Ionizing radiation: cancer in the bone marrow or stomach
2.Solar radiation: skin cancer
3. Electromagnetic fields: induction of cataracts of the eyes.
Explanation:
1. Radiation sickness occurs when exposed to very high doses of ionizing radiation. It may be acute or chronic. The risk for cancer is dose dependent and an accumulation effect begins if the doses are very low.
2. Skin cancer is malignant that is caused by the uncontrolled division and growth of skin cells, with the ability to invade healthy tissues.
3. The thermal effects of electromagnetic fields produced by radar waves include the increase in body temperature by more than 1º C. Its effects include the cataracts of the eyes, and physiological and thermo-regulatory responses as the body temperature increases .
