The term 'Infant BP: Normal' refers to the blood pressure of a normal infant. An infant's blood pressure is expected to be smaller than that of an adult due to their smaller size. Factors such as the infant's size, heart rate, and overall health can influence their blood pressure.
In this question, the term "Infant BP: Normal" refers to the blood pressure of a normal infant. The blood pressure of an infant is expected to be smaller than that of an adult because infants are shorter and their blood only feels a pressure of a shorter distance. The blood pressure of an infant is influenced by factors such as the infant's size, heart rate, and overall health.

Correct answer: A). The enzyme influences the speed of change from substrate to product
The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.
They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.
Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
The statement "The enzyme influences the speed of change from substrate to product" is correct. Option 1 is correct.
Enzymes are biological catalysts that speed up chemical reactions by lowering the activationenergy required for the reaction to occur. Enzymes do not undergo any permanent changes during the reaction and are not consumed in the process.
Enzymes are proteins that play a crucial role in biological reactions by facilitating the conversion of substrates into products. Substrates are the specific molecules that bind to the active site of an enzyme, forming an enzyme-substrate complex. The active site is a region on the enzyme's surface that has a complementary shape to the substrate.
When the substrate binds to the enzyme's active site, it undergoes a temporary change in shape, known as the induced fit model. This induced fit brings the reactive groups of the substrate close together, making it easier for the chemicalreaction to occur. As a result, the activation energy required for the reaction to proceed is significantly reduced.
The enzyme does not alter the nature of the reaction or the final products. Instead, it provides an environment where the reaction can occur more rapidly and efficiently. Once the reaction is complete, the enzyme releases the products, and it can then bind to new substrate molecules to catalyze additional reactions.
Enzymes are highly specific, meaning that each enzyme catalyzes a particular reaction with specific substrates. This specificity ensures that only the appropriate substrates bind to the enzyme, preventing unwanted side reactions in the cell.
In summary, enzymes and substrates are related through the process of enzyme-substrate interactions, where enzymes accelerate the conversion of substrates into products by lowering the activation energy required for the reaction. This crucial role of enzymes in biological processes makes them vital for maintaining the proper functioning of living organisms.

Answer:
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
The red line on the figure below shows how temperature varies with height (the temperature scale is given along the bottom of the diagram). The scale on the right shows the pressure. For example, at a height of 50 km, the pressure is only about one thousandth of the pressure at the ground.
Selective breeding ( also called {blank }) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotype traits (blank) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. (blank) animals are known as breeds , normally bred by a professional breeder , while domesticated plants are known as (blank) , cultigens , or cultivars. Two purebred animals of different breeds produce a (blank). Flowers , vegetables and fruit-trees may be bred by amateurs and commercial or no-commercial professionals: major crops are usually the provenance of the professinonals.
Answer Key
Selective breeding also called (artificial selection.) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics.) by choosing which typically animal or plant males and females will _exually reproduce and have offspring together. (Domesticated.) animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as (varieties.) , cultigens, or cultivars. Two purebred animals of different breeds produce a (crossbreed.) . Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals.
b. muscle and fat
c. age
d. gender
Muscle and fat will influencing flexibility is dependent upon individual behaviors. Option B is correct.
Flexibility is the ability of a joint or a group of joints to move through a full range of motion. It is influenced by several factors, including joint structure, muscle and fat, age, and gender. Among these factors, muscle and fat are particularly dependent upon individual behaviors.
Joint Structure: The anatomy of the joint itself, including the type of joint and the arrangement of ligaments and tendons, can influence flexibility. Some individuals may naturally have more flexible joints due to their unique joint structure.
Muscle and Fat: The length, strength, and flexibility of muscles and the amount of fat surrounding the joint area can significantly impact flexibility. Regular physical activity, stretching exercises, and conditioning of muscles can improve flexibility over time.
Age: Flexibility tends to decrease with age. As people age, their connective tissues, such as tendons and ligaments, may become less elastic, reducing joint flexibility. However, regular stretching and exercise can help maintain flexibility as one ages.
Gender: In general, women tend to be more flexible than men. This difference is partly due to physiological factors such as differences in collagen content and joint laxity between genders.
Muscle flexibility is closely related to the elasticity and length of muscles. Regular stretching exercises and activities that promote flexibility, such as yoga, can help improve muscle flexibility. Engaging in physical activities and exercises also helps reduce excess fat around the joints, which can enhance joint mobility and flexibility.
Hence, B. is the correct option.

Diffusion is the spontaneous movement of a substance from an area of higher concentration to an area of lower concentration.
Diffusion refers to separate the particles of some solution, that get the concentration differences in the process.
This is because of the spontaneous motion of the molecules.
So, diffusion refers to separate the particles of some solution, that get the concentration differences in the process.
