Motion energy refers to the energy related to an object's movement. When an object is in motion, it possesses kinetic energy, which is a form of motion energy.

The matching will be:

motion energy = energy related to an object's movement

chemical energy = stored energy related to positions of atoms within molecules

thermal energy = energy of motion of particles in a substance

nuclear energy = energy released when a nucleus splits or combines

gravitational potential energy = energy related to height

sound energy = energy generated by vibration of a string

Chemical energy is stored energy that is related to the positions of atoms within molecules. It is the energy that can be released or absorbed during a chemical reaction. When chemical bonds are formed or broken, energy is either released (exothermic reaction) or absorbed (endothermic reaction) in the process.

The ENCOD project was a collaborative effort aimed at identifying all functional elements in the human genome. It consisted of several phases, including the pilot phase, technology development phase, sequencing phase, and analysis phase.

What is ENCOD?

The ENCODE (Encyclopedia of DNA Elements) project was a collaborative research effort aimed at identifying all functional elements in the human genome. The project was launched in 2003 with the goal of creating a comprehensive catalog of functional elements, such as genes, regulatory elements, and chromatin modifications, and to understand how these elements work together to control gene expression and cellular function.

Since the database that Ananya accesses contains functional data, it was likely created during the analysis phase of the ENCODE project. During this phase, the raw data generated in the sequencing phase was analyzed and interpreted to identify functional elements such as genes, regulatory regions, and chromatin modifications.

A quantitative observation that the student can make to compare the amounts of \(CO_2\)given off by yeast provided with different amounts of sugar is the measurement of the size or volume of the balloons. Larger balloons indicate a greater volume of\(CO_2\) produced by the yeast.

A quantitative observation that the student can make to compare the amounts of \(CO_2\) given off by yeast provided with different amounts of sugar is the measurement of the balloon's size or volume.

The student can measure the diameter or circumference of each balloon, or alternatively, the volume of each balloon. This can be done using a ruler, measuring tape, or by submerging the balloon in water and measuring the displaced volume.

By comparing the sizes or volumes of the balloons, the student can infer the relative amounts of \(CO_2\) produced by the yeast. The larger the balloon, the greater the volume of \(CO_2\)released.

Quantitative observations provide numerical data that can be analyzed and compared. In this case, the size or volume of the balloons provides quantitative information about the amount of \(CO_2\) given off by yeast with different sugar amounts.

It is important for the student to ensure that the conditions of the experiment are controlled and consistent for each container. This includes using the same type and amount of yeast, maintaining the same temperature and time duration, and providing accurate measurements of the sugar amounts.

OFFICIAL SAMPLE ANSWER (Do not copy verbatim):

Hypothesis 1: The natural nutrients in compost will cause the tomato plants to grow at a faster rate than they grow when given artificial fertilizer.

Hypothesis 2: The artificial fertilizer is formulated specifically for tomato plants, so it will cause the plants to grow at a faster rate than they grow when given compost.

Explanation:

If questioned for situation below.....

"Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.

A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.

"

1. compost pits and manure use, bio gas can be produced

2. using natural compost replenishes the soil fertility in the long run unlike the chemical fertilizers are two possible hypotheses for the student’s experiment

The basics of experiment is to test the hypothesis what we set previously and it is a foundation of the scientific method, types of experiments include controlled experiments, field experiments, and natural experiments.

The key steps taken in scientific method are observations, ask a question, making of hypothesis, design and conduct experiment, result, accept or reject or repeat the hypothesis from result.

The most important parameter taken in an experimental set up is variable which can be  dependent, independent and controlled variables where the independent variable is something which can not influenced by other factor.

A dependent variable can be changed by the influence of independent variable and Control variable can be  used to check bias of experiment.

C. More young children live in Country 1 than in the other countries.

Explanation:

The described graph shows that more young children live in Country 1 than in the other countries. This is clearly stated in the first paragraph: This is the greatest percentage of any 4-year age span in all three countries. This automatically means that options B and D are incorrect.

Option A is the second-best one. However, the fact that there are more young children in Country 1 doesn't necessarily mean that their death rate is lower. It could be, but correlation doesn't equal causation. There are more young children probably because the younger population is more present in that country and more children are born.

This is why option C is the correct one.

Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.

Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.

Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.

Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

each enzyme works on one particular substrate :)

Answer:

False

Explanation:

Enzymes can only react with one different substance because they are very specific.

They have an active site which makes them specific, because this active site restricts which substrates (reactants) can bind to the enzyme.

So, this statement is false, because enzymes can only react with one substance since they are specific.

Name of flower structure: Sepal, Function of sepal: protection of the flower. Name of flower structure: Petal, Function: attracting the pollinators. Name of flower structure: Stamen, Function: Male reproductive structure. Name of flower structure: Pistil, Function: Female reproductive structure.

Sepals are the outermost whorl of modified leaves that protect the flower during the bud stage. They also help to support the petals after the flower has bloomed.

Petals are brightly-colored, often fragrant structures that are responsible for attracting pollinators to the flower. They are also responsible for protecting the reproductive structures of the flower.

Stamen is the male reproductive structure of the flower. It consists of two parts: the anther, which produces as well as releases pollen; and the filament, which supports the anther.

Pistil is the female reproductive structure of the flower. It is composed of three parts: the stigma, which receives the pollen; the style, which supports the stigma; and the ovary, which contains the ovules that eventually develop into seeds after fertilization.
