While you’re waiting for the lactase solution to cool, read the directions on the test strips. The test strips in the Edmentum lab kit will react to glucose within a few seconds. If you use different strips, the reaction time may vary. Now follow these steps to test the solutions. Record your data in the answer space.


Milk and water solution: Fill the first test tube one fourth full of milk. Fill the small graduated cylinder with water and gently add it to the milk in the test tube until the test tube is half full. Use the stirrer to thoroughly mix the solution. Then insert the test strip for 10 to 20 seconds. Look at the test strip, and record whether it changed color. Wash the stirrer.

Milk and lactase enzyme solution: Fill the second test tube one fourth with milk and one fourth with the lactase solution. Use the stirrer to thoroughly mix the solution. Insert the test strip for 10 to 20 seconds, and record whether it changed color. Wash the stirrer.

Answer 1
Milk and lactase have glucose together because the enzyme lactase will break down the lactose molecule so the test strip can see the entire glucose molecule

Both the mother and father of a son with colorblindness have normal vision. From whom did the son inherit the gene for colorblindness

Answers

Answer:

The blind son inherited his gene for colorblindness from his father.

Explanation:

The X chromosome is where color blindness is most frequently inherited as a recessive trait. In genetics, this is referred to as X-linked recessive inheritance. As a result, men tend to be affected by the illness more frequently than women (8% male, 0.5% female).

What are the characteristics of colorblindness inheritance?

There is a 50% chance that the sons of a color-blind father and a mother who has the gene will also be color-blind. However, their daughters will have a 50% risk of having the condition and a 100% chance of carrying the gene.

The 23 chromosome is known as the “sex chromosome,” and it is passed from mother to son. Red/green color blindness is the most common type of this condition.

As it aids in identifying sex, the 23rd chromosome is known as a sex chromosome.

Therefore, The blind son inherited his gene for colorblindness from his father.

The anterior rami of spinal nerves ______ are called intercostal nerves because they travel in the intercostal space sandwiched between ______.

Answers

Answer: T1-T11; two adjacent ribs

Explanation:

The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.

What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.

1. What happened to the pH of the substances when the size of the sample was increased or
decreased?

2. What happened to the pH when the sample was diluted? Did the material change from its original classification as an acid/base/ or neutral?

3. Describe a neutralizing reaction and give the neutral products?

4. Predict the general pH that is the result of combining a strong acid with a weak base?

Answers

Explanation:

An acid-base reaction or neutralization reaction is a chemical reaction that occurs between an acid, for example hydrochloric acid, and a base, sodium hydroxide.

The word "salt" describes any ionic compound whose cation comes from a base (Na + from NaOH) and whose anion comes from an acid (Cl- from HCl). Neutralization reactions are generally exothermic, which means that they give off energy in the form of heat. They are often called neutralization because when an acid reacts with a base, they neutralize each other's properties.

There are several concepts that provide alternative definitions for the reaction mechanisms involved in these reactions, and their application to related problems in solution. The word neutralization can be interpreted as annihilation or as elimination, which is not far from the truth. When an acid is mixed with a base both species react to different degrees that depend largely on the concentrations and volumes of the acid and the base can be considered as an illustration the reaction of a strong acid that is mixed with a weak base, this The latter will be completely neutralized, while a portion of the strong acid will remain in solution, depending on the moles that reacted with the base. Three additional alternatives that arise from mixing an acid with a base can be considered:

A strong acid is mixed with a strong base: When this happens, the species that will remain in solution will be the one that is in greater quantity than the other.A weak acid is mixed with a strong base: The solution will be basic, since it will be the base that remains in the reaction.A weak acid is mixed with a weak base: If this happens, the acidity of a solution will depend on the acid constant of the weak acid and the concentrations of both the base and the acid.Despite the differences in definitions, its importance is evident in the different methods of analysis, when applied to acid-base reactions of gaseous or liquid species, or when the acidic or basic character may be somewhat less evident. The first of these scientific concepts of acids and bases was provided by the father of chemistry, the Frenchman Antoine Lavoisier, around 1776.

how can one eukaryotic gene lead to one transcript, but multiple different proteins?

Answers

Answer:

source- The ability of certain genes to form multiple proteins by joining different exon segments in the primary trans-cript is called alternate splicing and has caused a reexamination of the concept of “one gene, one protein.

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. ... Human genes typically contain several "exons," or DNA sequences that code for amino acids, the building blocks of proteins.

in your own words-

the flexibility of bound factors to make multiple proteins by connection totally different DNA segments within the primary trans-cript is termed alternate junction and has caused a reexamination of the thought of “one gene, one macromolecule.

Scientists have long noted that it's attainable for one factor to provide slightly totally different styles of a similar macromolecule by skipping or together with bound sequences from the informational RNA. ...

Why do parrots mimic people?

Answers

Answer:

Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.

Explanation:

Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.
