what are enzymes for grade 8?
Answer:
Enzymes are proteins that participate in cellular metabolic processes that speed up the rate of reaction between biomolecules. Basically enzymes are proteins that catalyze reactions. Each enzyme has a specific function, and one enzyme acts on one substrate - the material that binds to the enzyme's active site. The shape of the enzyme has to match the substrate shape for the reaction to occur. How enzymes work is that they bind molecules so they are held in a geometric configuration that lets the reaction to occur.

one way an epsp (excitatory postsynaptic potential) could facilitate depolarization of the postsynaptic membrane is___
By allowing positively charged ions to enter the postsynaptic cell through ion channels opened by the depolarization of the postsynaptic membrane. This influx of ions causes the membrane potential to become more positive, thus resulting in further depolarization.
An EPSP (Excitatory Postsynaptic Potential) is a type of nerve impulse that is generated when an excitatory neurotransmitter is released from the presynaptic terminal of a neuron. This neurotransmitter binds to an enzyme (usually acetylcholine-receptor) on the postsynaptic membrane, causing the postsynaptic membrane to become depolarized (less negative).
Step 1: An action potential is generated in the presynaptic neuron, which causes the vesicles containing neurotransmitters to release glutamate into the synaptic cleft.
Step 2: The glutamate binds to the postsynaptic membrane, specifically to the glutamate-receptors (usually AMPA receptors).
Step 3: The binding of the glutamate to the receptor causes an influx of positively charged ions (such as sodium ions) into the postsynaptic cell, leading to a depolarization of the postsynaptic membrane.
Step 4: The depolarization of the postsynaptic membrane causes a change in the membrane potential of the postsynaptic cell, leading to an EPSP.
Step 5: The EPSP depolarizes the postsynaptic membrane further and can trigger an action potential in the postsynaptic neuron.

a. Stripe 2 would expand toward the tail of the embryo. b. Stripe 2 would become fainter.
c. Stripe 2 would expand toward the head of the embryo.
d. Stripe 2 would become narrower. e. All 7 stripes would disappear.
Stripe 2 would become fainter in flies that lack the gene that encodes Bicoid. Thus the correct answer is option (B).
The homeotic protein known as Bicoid is encoded by the Bicoid maternal effect gene in Drosophila. The anterior-posterior (A-P) axis is shaped during Drosophila development by a gradient in the concentration of the homeotic protein known as Bicoid. Bicoid was the first protein that was demonstrated to have morphogen-like properties. Although Bicoid is essential for Drosophila and other higher dipterans to thrive, it is absent in most other insects, where alternative genes take their place. The bicoid gene plays a crucial role in the early embryo's establishment of the head-to-tail axis. Without a bicoid, the embryo cannot form a head or a tail; instead, its body parts develop in an arbitrary order. This is due to the bicoid's role in patterning the embryo's anterior-posterior axis. To put it another way, it aids in figuring out which end of the embryo will develop into the head and which end will develop into the tail.

a. The circulatory system responds to an elevated blood pressure, reflexively causing the heart rate to decrease.
b. The digestive system normally secretes the inactive enzyme pepsinogen. When a person eats, the pepsinogen is converted into the digestive enzyme pepsin.
c. The respiratory system sends nerve impulses to increase breathing rate during periods of high stress, which can produce additional stress due to a feeling of loss of breath.
d. The endocrine system measures the level of blood testosterone. High levels of the hormone will signal the hypothalamus to stop the production of other hormones like GnRH and LH.
An example of a correct prediction of a positive regulatory feedback mechanism is option b.
What is positive regulatory feedback mechanism in body?
Positive regulatory feedback mechanism is a type of feedback loop in the body which occurs when the output of a process stimulates the same process to further increase the output. For example, during exercise, the body produces adrenaline which stimulates the heart to beat faster and also increases the production of adrenaline. This creates a positive feedback loop, as the increased adrenaline stimulates the heart to beat faster, which in turn increases the production of adrenaline. This mechanism ensures that the body continues to produce the necessary hormones and other substances to sustain the activity. In other words, positive regulatory feedback mechanism is the body's way of ensuring that the body maintains its equilibrium and is able to carry out its activities without any disruption.
The chemical pepsin is used by the stomach to digest proteins. It starts by secreting an enzyme called pepsinogen, which is inactive. When food is consumed and the body needs to digest it, pepsinogen is converted into pepsin. The process of turning more pepsinogen molecules inside the stomach into pepsin triggers a positive feedback loop, allowing the stomach to produce enough of the protease to break down proteins.

for yellow skin color, 100% of the offspring have red skin color. Based on this information,
how do the alleles for skin color interact?
* 2 point:
Answer: Red skin color is dominant, it is a simple trait controlled by one gene.
Explanation:
RR x yy = Ry, Ry, Ry, Ry
Answer:
Red skin color is dominant

During which stage(s) of plant seed germination (1-5) is cellular respiration required to supply all plant cells with the ATP required to fuel growth and development? Select ALL that apply.
Stages 1, 2, 3, 4, & 5
During Stages 1, 2, 3, 4, & 5 of plant seed germination is cellular respiration required to supply all plant cells with the ATP required to fuel growth and development.
Seed germination is the method of growing plants from seeds rather than purchasing pre-grown plants. When compared to germinating seeds directly in the soil, sprouting seeds indoor environment is an efficient way to boost the germination rate. The procedure by which a microbe develops from a seed or spore is known as germination.
Cellular respiration produces ATP molecules, which provide energy for seed germination and fuel the cellular activity that eventually forms the plant.
As cellular respiration occurs in germinating seeds, the carbon dioxide released is proportional to the oxygen taken up by the seed. This CO2 (gas) interacts with Calcium oxide to establish calcium carbonate (solid), reducing the amount of gas and allowing the water to rise.

which model represents the general structure of a highly branched carbohydrate?
Answer:the answer is C
Explanation:
C model represents the general structure of a highly branched carbohydrate. So, the correct option is (C).
What is Carbohydrate?The word 'carbohydrate' is derived from a French word 'hydrate de carbon' meaning 'hydrate of carbon' where this class of organic compounds have their general formula [tex]C_n(H_2O)_n.[/tex]
Carbohydrates are defined as macronutrients which are one of the three main ways our body gets its energy. These are called carbohydrates because they contain carbon, hydrogen and oxygen at the chemical level. These essential nutrients include sugars, fibers and starches found in grains, vegetables, fruits and milk and other dairy products. Carbohydrates are the basic food group that play an important role in healthy living.
There are three types of Carbohydrates which are:
