Multiple ChoiceTrue/FalseMatchingShort AnswerFill-in-the-blanksEssaysOral ExamsCheckboxesMultiple choice, objective response, or MCQ (for Multiple Choice Question) is a form of an objective assessment in which respondents are asked to select only correct answers from the choices offered as a list.
True/False tests contain statements that the student marks as being either true or false. In order to qualify as true, all parts of the statement must be true. In general, true-false tests check your knowledge of facts.
A matching question is two adjacent lists of related words, phrases, pictures, or symbols. Each item in one list is paired with at least one item in the other list. Matching may be considered to be a variant of multiple-choice in which more than one choice is correct.
While opinions may differ, most teachers believe a short answer question typically requires a "short" answer. That doesn't mean an answer lacking depth analysis or information. It simply means an answer that is concise and includes just enough information to accurately and fully answer the question being asked.
Fill in the Blank questions are not opinion-based, which means that learners must be able to use the information they have mastered during the lesson to correctly answer the question. Fill in the Blank questions usually contain a sentence or paragraph featuring a blank space.

Why do volcanoes usually form at plate boundaries?
Answer:
When plates move away from each other at divergent plate boundaries, interesting things happen. For example, when plates move apart, molten rock from the Earth's core ascends and forms new crust. ... This molten rock can rise up to the surface, forming a volcano, and causing volcanic eruptions.
write an article on the topic 'impact of population on ecosystem'.
Abstract -
The rapid increase of human population is putting an incredible strain on our environment. While developed countries continue to pollute the environment and deplete its resources, developing countries are under increasing pressure to compete economically and their industrial advancements are damaging as well. The demands that this growth places on our global environment are threatening the future of sustainable life on earth. One of the largest environmental effects of human population growth is the problem of global warming. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate. Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water. The growth of population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems that must be addressed in order to ensure that life on earth will be sustainable throughout the next century. Keywords: Industrial advancements, Land and soil degradation, global warming, Climate change, Air and water pollution, Deforestation, Physical environment.
Does the amount of energy from the food eaten (Kcal) by each organism equal the amount of energy used by each organism? Support your answer by showing your calculations. (Show your work > math icon)
Answer:
Explanation:
This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.
How does independent assortment increase genetic variation in Meiosis?
Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.

Explanation:
which source of calories causes the body to expend the most energy during digestion?
The consumption of energy during digestion is known as the thermic effect of food.
Consuming food is how we get the energy needed to sustain the basic functions of our organisms. Digesting this food, however, also takes up energy. In fact, about 10% of the energy we expend daily is allocated towards the digestion and storage of food and nutrients. This is known as the thermic effect of food.
On average, the food with the highest thermic effect is that of vegetables and fruit with high water compositions. This, however, falls a bit out of the scope of the question given that these foods are often very low in calories. The food that is high in calories and has a high thermic effect is protein. On average, proteins consume 20-30% more energy to digest than other sources of calories.

Give advantages of endothermic animals
Answer:
The advantages of endothermy are well known: the ability to occupy thermal niches that exclude many ectothermic vertebrates, a high degree of thermal independence from environmental temperature, high muscular power output and sustained levels of activity, to name but a few.
The major advantage of endothermy over ectothermy is decreased vulnerability to fluctuations in external temperature. Regardless of location (and hence external temperature), endothermy maintains a constant core temperature for optimum enzyme activity.

1. State Mendel's Law of Inheritance.
2. What are the two alleles for flower color in snapdragon?
3. State the Law of Non-Mendelian Inheritance in snapdragon.
Answer:
1
Explanation:
he was able to find chromosomes in plants
Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the conclusion that genes are inherited as distinct, paired units from each parent.
What is Non-Mendelian Inheritance?
Inheritance of features with a more complicated genetic base than one gene with two alleles and total dominance is referred to as non-Mendelian inheritance.
One allele may not always be dominant over another, resulting in a phenotype that falls between the two parents in certain people.
Incomplete dominance is the name given to this inheritance pattern. Snapdragon flowers, for instance, exhibit partial dominance.
When both alleles are present at the same time, this pattern of inheritance is referred to as partial dominance, since neither allele is totally dominant over the other.
Therefore, red and white snapdragons cross to produce exclusively pink progeny.

Enzymes are the bio-catalysts. Their presence can increase the rate of a reaction. Enzymes are most effective at a particular pH and temperature but can also function over a range of pH and temperature. Thus, correct option is A.
What are Enzymes?Enzymes are the biocatalysts which are responsible for increasing the rate of a chemical reaction. The enzymes increase the rate of a reaction by decreasing the activation energy which is required by the reactant molecules to collide and form products.
Enzymes are found to function over a range of pH, temperature, and solvents. Enzymes work over a range of different conditions. The value of pH and temperature at which enzymes show highest activity is called optimum condition. Below and above this point, enzymes function but the activity will be lesser than that in the optimum condition.
Therefore, A is the correct option. Enzymes are most effective at optimum condition of pH and temperature.
