Answer:
Identify enzyme: Enzymes are named by adding the suffix -ase to the name of the substrate that they modify or the type of reaction they catalyze(dehydrogenase, decarboxylase)
Identify substrate: the substrate is a molecule upon which an enzyme acts.Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.
Describe: Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. ... The enzyme's active site binds to the substrate.
I hope this helps :)
The enzyme in this case is lactase and the substrate is lactose.
What is the enzyme-substrate relationship?In biochemistry, the molecule on which an enzyme operates is known as the substrate. Enzymes catalyze chemical reactions involving the substrate(s). The substrate is changed by the active site into one or more released products. The active site is then ready to accept a fresh substrate molecule.
To catalyze a reaction, an enzyme will grab (bind) to one or more molecules of the reactant. These substances serve as the enzyme's substrates. In certain reactions, a single substrate can be broken down into a variety of products. Others involve the joining of two substrates to create a larger molecule or the switching of parts. In fact, every biological reaction may probably be sped up by an enzyme.
The fundamental idea should be relatively evident despite slight differences in the definitions of the substrate in general chemistry and biology. A substrate is commonly understood in chemistry as a chemical substance that may be changed by the action of another substance. Without the aid of an external catalyst or enzyme, the transformation takes place in the substrate itself, and in most cases, given enough time, it may happen on its own.
Therefore, lactase is the enzyme and lactose is the substrate.

In a nutrient medium that lacks histidine, a thin layer of agar containing around 10^9 Salmonella typhimurium histidine auxotroph produces around 13 colonies over a two day incubation period at 37 degrees centigrade. How do these colonies arise in the absence of histidine? The experiment is repeated in the presence of 0.4 micrograms of 2-aminoanthracene. The number of colonies the number of colonies produced over 2 days exceeds 10,000. What does this indicate about 2- anthracene? What can you surmise about its carcinogenicity?
Answer:
Reverse mutations in the colonies enabled to recover the ability to synthesize histidine. The 2-aminoanthracene is a chemical agent that induce mutations and therefore it is potentially a carcinogen.
Explanation:
A reverse (suppressing) mutation is a type of mutation capable of restoring the activity of previously mutated genes. On the other hand, 2-aminoanthracene is an aromatic amine carcinogen capable of inducing hepatic and skin tumors. In this case, 2-aminoanthracene has been used to induce reverse mutations at loci responsible for the synthesis of histidine.

a weight loss client is currently exercising 5+ hours a week and hits a plateau what adjustments should a trainer suggest?
A. increase k/cal by 250, decrease k/cal by 100, C. increase k/cal by 100 OR D. Decrease k/cal by 250
Answer: D. Decrease k/cal by 250
Explanation: An individual can be said to habe hit a plateau, if such person fails to get or feel any noticeable changes or experiences stagnation in the quest to achieve a certain level. In the context of exercising and shedding body fat using the scenario above, the client was currently exercising at 5+ hours per week, when she started, there was visible changes, however, after some time, she discovered that the changes had become stagnated and it was just all the same, such person could be said to have hit a plateau, to curb this, since the client is aiming to lose weight, such person should decrease daily intake of calories per day by 250. These remains a reduction in the daily fat intake and then the client reassess if there is a noticeable change.

The cell bodies of motor neurons to skeletal muscles are located in the A. Posterior/dorsal gray horns B. Limbic system C. Anterior/ventral gray horns D. Gray commissure
The cell bodies of motor neurons to skeletal muscles are located in the anterior/ventral gray horns.
Neurons are cells characterized by a body (called soma), and different kinds of prolongations that will have the task to carry the information to other neurons or tissues - these prolongations are axons (which are usually very long) and dendrites (much shorter than axons).
The motor neurons are the ones that conduct the electric impulse from the motor cortex in the brain to the skeletal muscles in our bodies, making muscle contraction and movement possible.
There are two types of motor neurons:
Upper motor neurons: Their cell bodies are located in the motor cortex in the precentral gyrus of the brain. Their axons synapse onto interneurons in the spinal cord.Lower motor neurons: These neurons have their cell soma located in the anterior gray horns of the spinal cord - from that place, their axons will exit the spine to reach the skeletal muscles that we want to contract to perform specific tasks such as running or grabbing a glass of water.Thus, we can conclude that the somas of lower motor neurons that transmit its impulse to skeletal muscle are located in the anterior gray horns of the spinal cord.

Bile:_______
A. digests proteins in the small intestine.
B. emulsifies fats in the small intestine.
C. is made by the gallbladder and stored by the liver.
D. activates trypsin in the small intestine.
E. activates the pancreas.
⚘ Emulsified fats in the small Intestine (B)
Explanation:-Bile is not an enzyme which is made in the liver which helps in the emulsification of fats. Here, Emulsification means the break down of larger molecules of fat into small molecule. The bile is temporarily stored in the Gall Bladder.
The bile juice is then released into the duodenum(the first part of small intestine) through hepato pancreatic duct. The duct carries both enzymes of pancreas and bile. They digest the food in the small intestine[tex].[/tex]

The majority of thyroid hormones are secreted as ______but small amounts of _____is also secreted from the follicle.
Answer:
The correct answer is - T4, and T3.
Explanation:
The Thyroid glands are butterfly shape glands madeup of microscopic spherical structures known as thyroid follicles made up of cuboidal follicular cells. These cells produces the both major hormones of thyroid gland T4, and T3.
The majority of thyroid hormones are produced as T4 hormones approximately 80% but a small amount of 20% is released in the form of T3 hormones. However, the most active form of the thyroid hormone is T3 and to act on target cells, one iodine molecule have to be removed to convert T4 to T3.

Devon is playing with a yo-yo. A yo-yo has an axle in the middle of two plastic halves. A string is tied around this axle. As Devon moves his hand, the yo-yo goes up and down. The yo-yo converts potential energy to kinetic energy as it moves. Which of the following pictures represents the yo-yo with the most potential energy? A. X B. Y C. Z D. W
Answer:
second image or B. Y
Explanation:
Potential energy is defined as the stored energy of an object when work is done against a force.
The second image in which yo-yo is ready to stretch out, represents the yo-yo with the most potential energy because the distance is highest from the ground and so yo-yo at this position will have highest gravitaional potential energy. The potential energy will be converted into kinetic energy when released in air.
Hence, the correct image is "second image" or "B. Y"

Explanation:
Why are male cats unable to express both orange and non-orange colors simultaneously in the same way as female cats?
O male cats only have one X chromosome
O only female cats inherit non-orange genes
O male cats have a dominant Y chromosome
only female cats inherit orange genes
The gene that codes for orange/non-orange color is X-linked. Female cats can express orange and non-orange simultaneously. Males, who only have one X chromosome, can express either orange or non-orange.
-----------------------------------------------
Male cats can only express one or two coat colors, but not three as females do. The combination of three simultaneous colors seems to be exclusive for females.
In cats, hair color is coded by different genes. In the particular case of orange color, we are referring to a codominant, diallelic, X-linked gene. Chromosome Y does not have an associated gene for the orange color.
The orange gene is diallelic, being
O the dominant allele ⇒ codes for orange ⇒ inhibits the expression of blacko the recessive allele ⇒ codes for not-orange ⇒ allows the expression of blackMales, who carry only one X chromosome, can be either
orange ⇒ X⁺Y (Where + symbol represents the dominant allele O)non-orange ⇒ X⁻Y (Where - symbol represents the recessive allele o)But, since females carry two X chromosomes, they can express either
orange ⇒ H0m0zyg0us dominant ⇒ X⁺X⁺ non-orange ⇒ H0m0zyg0us recessive ⇒ X⁻X⁻ combination of black and orange ⇒ Heter0zyg0us ⇒ X⁺X⁻----------------------------------------
