The active site is the portion of an enzyme that binds specifically to the substrate or substrates. Enzymes are highly specific due to the shape and chemical environment of their active sites.
Explanation:The portion of an enzyme that binds specifically to the substrate or substrates is referred to as the active site. The active site is a unique region within the enzyme where the substrate molecules can bind and undergo a chemical reaction. Enzymes are highly specific due to the shape and chemical environment of their active sites, allowing them to only bind to compatible substrates.
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Explain have a fats sugars and or starch contained in seeds or milk are useful for the plant sprouting from the seed or the baby mammal
Final answer:
Starch, which is made up of the glucose polymers amylose and amylopectin, is an energy store in seeds that supports the growth of the embryo during germination and serves as a valuable food source for humans and other animals.
Explanation:
Fats, sugars, and starches found in seeds or milk serve crucial roles for both plants and mammals. In the context of plants, starch is a form of energy storage, comprising two types of glucose polymers: amylose and amylopectin. When a seed germinates, the stored starch provides much-needed energy for the developing embryo. These stores are also beneficial to mammals, such as humans, who consume them as a food source. Enzymes in our digestive system, like salivary amylase, break down starch into maltose and glucose, which our cells can then absorb and use for energy.

The suffix in the medical word hematocrit means ________.
The suffix 'crit' in hematocrit means 'to separate' or 'to judge'.
The suffix 'crit' in the medical term hematocrit is derived from Greek and means 'to separate' or 'to judge'. In the context of a hematocrit test, it refers to the process of separating blood cells from plasma to measure the volume percentage of erythrocytes (red blood cells) present. A hematocrit test involves centrifuging a blood sample to cause the heavy erythrocytes to settle at the bottom of the tube, which allows for a measurement of the proportion of RBCs relative to the entire blood sample. A normal hematocrit value is usually around 45%, and it is a critical indicator of the oxygen-carrying capacity of blood, with low hematocrit values indicating possible anemia.

The rigth answer is cell membrane.
A cell membrane distinguishes a fundamental cellular structure formed from a double layer of phospholipids associated with other lipids, proteins and carbohydrates.
The membrane of the cell, also known as the plasma or cytoplasmic membrane, is a biological membrane (biomembrane) that separates the interior of all cells from the external environment.
The plasma membrane, cytoplasmic membrane or plasmalemma delimits the cytoplasm of the cell. Organelles are surrounded by a single cell membrane (peroxisomes, lysosomes, endoplasmic reticulum, dictyosomes, vacuole) or double (nucleus, plastids).

Describe the chemical structure of a cell membrane
The cell membrane is made up of a double layer of phospholipids, often known as a lipid bilayer, with proteins and cholesterol molecules embedded within. These components are arranged in a versatile fluid mosaic model allowing for flexibility and movement of the cell.
Explanation:The cell membrane, also known as the plasma membrane, is the outer boundary of a cell. Its primary function is to protect the cell from its surroundings. It's composed mainly of a double layer of phospholipids (a lipid bilayer). Each phospholipid molecule has a hydrophilic (water-loving) head and two hydrophobic (water-fearing) tails. These phospholipids arrange themselves so that the hydrophilic heads face outwards towards the watery environments, both inside and outside the cell, while the hydrophobic tails face each other inwards.
Embedded within this phospholipid bilayer are various proteins and cholesterol molecules. The proteins have various functions, including the transport of molecules across the membrane. The cholesterol molecules help maintain the fluidity (flexibility) of the membrane. This entire structure is also called the 'fluid mosaic model' of the cell membrane because the proteins are embedded in a sea of lipids, and everything can move around fluidly.

Exercise releases chemicals in our bodies called __________ , which make us feel good.
Answer:
Endorphin is released
Explanation:
When we exercise, endorphin is released in the body. Endorphin produces a positive feeling. Due to the release of this chemical, we feel like as if our pain has reduced and hence endorphin fall into the category of analgesics. Endorphin is released by several parts of the body including the brain and spinal cord and bind to the neuron receptor in the same way as a pain medicine does.
Hence, while doing exercise it is the endorphin which is released in the body to make us feel good.

In a transformation, the heat produced by friction is evidence that energy is conserved.
How enenrgy is consrved?But altogether, neither new nor lost energy is added to the system. When moving sand makes contact with an obstruction, friction is generated that causes it to stop, and the kinetic energy of the contact is converted to thermal energy or heat.
Energy cannot be generated or destroyed, says the law of conservation of energy, heat produced by friction is evidence that energy is conserved.
The overall quantity of energy is constant during all transformations. All of the initial energy will be accounted for if you sum up all the new forms of energy that result from a transition.
Therefore, in reality, friction's ability to generate heat is proof that energy is conserved.

Large predatory fish usually are found at the 3rd and 4th trophic level of an energy pyramid. what does this mean in terms of energy loss
Final answer:
Large predatory fish are located at the 3rd and 4th trophic levels of an energy pyramid. There is a significant loss of energy as it moves through the trophic levels.
Explanation:
Large predatory fish typically occupy the 3rd and 4th trophic levels of an energy pyramid. This means that they consume organisms from lower trophic levels, such as herbivores and smaller carnivores, to obtain energy. However, there is a significant loss of energy as it flows through the trophic levels, resulting in less energy being available at higher levels. Only about 10% of the energy from one trophic level is transferred to the next level, with the remaining 90% being used for metabolic processes or lost as heat.
