Consider an experiment where your goal is to isolate Bruton’s tyrosine kinase (BTK) enzyme from a whole‑cell lysate. You have an affinity chromatography column with a tyrosine kinase inhibitor molecule covalently attached to the beads. The tyrosine kinase inhibitor binds and inhibits BTK. As a result of the experiment, you are able to elute BTK from the column, but in a mixture of other tyrosine kinases. Why are tyrosine kinases other than BTK present in the eluate?
Answer:
Kinase inhibitor has low specificity
Explanation:
In humans, Bruton's tyrosine kinase (BTK) is a protein tyrosine kinase encoded by the BTK gene, which plays key functions in the mechanisms of development, differentiation, and signaling of B-lymphocytes. In the last years, many BTK inhibitor drugs have been developed, including Ibrutinib, Acalabrutinib and Zanubrutinib. It has been shown that kinase inhibitors may have low specificity because these molecules exhibit a high conservation level in the ATP binding pocket, which is known as 'inhibitor promiscuity'.

Which are considered two of the special properties that are used to identify certain minerals? hardness and luster magnetism and fluorescence streak and color cleavage and fracture
Two of the unique characteristics that are utilized to identify specific minerals are regarded to be magnetic and fluorescence. Therefore, choice B is correct.
Minerals are chemical compounds that naturally occur in their purest form and have a well-defined composition and crystal structure. A compound is referred to as a distinct mineral if it naturally occurs in a different crystal form. A mineral's chemical makeup can differ depending on the presence of minute impurities that are present in trace amounts.
The physical characteristics of minerals include color, streak, luster, specific gravity, and cleavage; they do not exhibit magnetism. In essence, magnetism is a physical characteristic of minerals; it lacks these components. have no so-called diamagnetic magnetism. Diamagnetic materials include quartz and apatite.

Would all of the planets be on the same side as the Earth? Why?
Answer: Yes
Explanation:
Our Solar System is an orderly place, with the four inner planets, the asteroid belt, and the gas giant worlds all orbiting in the same plane around the Sun. Even as you go farther out, the Kuiper belt objects appear to line up with that same exact plane. Given that the Sun is spherical and that there are stars appearing with planets orbiting in every direction imaginable, it seems too much of a coincidence to be random chance that all these worlds line up. In fact, practically every Solar System we've observed outside of our own appears to have their worlds line up in the same plane, too, wherever we've been able to detect it.
Lets consider the group known as tetrapods, these include Salamanders, Turtles and the Leopard. A. Are they a monophyletic group? (1 point) B. Is the Amniotic Egg ancestral or derived for this group (tetrapods)? (1 point) C. Is the Vertebral Column ancestral or derived for this group (tetrapods)?

Explanation:
Lake Baikal is the oldest and deepest lake in the world. It is found in the middle of Siberia. In Lake Baikal there are 32 species of sculpin (a type of fish). All of these species are only found in Lake Baikal. You want to understand the evolutionary history of this group of fish and how speciation occurred for sculpin in Lake Baikal. A. What mechanism of speciation do you think has occurred in Lake Baikal sculpin. Provide your answer in the form of a hypothesis. (2 points) B. What are TWO types of additional information you would want to gather in order to test your hypothesis from A? (5 points)
Answer:
The. Two populations of sculpin lived on Lake Baikal, but a genetic change in one of the populations prevented them from crossing, thus creating a new species of sculpin.
B. The additional information I would use to test the hypotheses would be: 1) is there any species of fish similar to sculpin in the same lake? 2) what is the genetic change presented by the sculpins?
Explanation:
My hypothesis about sculpin fish states that sympathetic speciation has occurred. This speciation occurs when two populations of the same species can no longer promote crossings between them, thus creating an evolutionary process, which results in the creation of two distinct species, in the same habitat. I believe that this type of speciation is more common to happen in aquatic environments and in fish, since these environments present less physical barriers than the terrestrial environment. This usually occurs with the existence of genetic modifications within one of the populations. As a result, to test my hypothesis, I would need information about the existence of species similar to sculpin within the same lake, in addition to knowing what genetic differences between them would promote this type of speciation.
A manager wanted to test whether the amount of noise in a clothing factory affected how
much work employees accomplished. Three groups of employees were tested every day
over a 5-day period. All three groups did the same type of work, they were all equally trained
to do the work, they used the same equipment, and they were tested the same time of day.
Group one was given headphones that blocked out all of the outside noise. Group two was
given headphones that blocked out some of the noise. Group three was not given anything
to block out the noise. The number of shirts made by the employees in one hour was
determined.
Which problem is being tested in this experiment?
How long does it take to make a certain brand of clothing?
O Which employees need more training?
O Does the amount of noise affect how much work employees do?
O Are headphones unsafe in the factory?
Answer:
The problem that is being tested is Does the amount of noise affect how much work employees do?
Explanation:
When a manager wanted to test whether the amount of noise in a clothing factory affected how much work employees accomplished, he performs an experiment modifying the amount of noise that employees endure through the use of headphones.
What the manager wants to know for sure is how much the amount of noise in the factory affects the productivity of the employees, which is expressed in the amount of shirts they can make exposed or not to the noise.
Noise reduction with the use of headphones would be expected to improve employee productivity.
The other options do not really identify the study problem, since the time it takes to make a certain brand of clothing, employee training or safety in the use of headphones in the factory is not being investigated.

Which is the correct isotopic notation for a potassium ion that has 19 protons, 20
neutrons, and 18 electrons? *
i think that it is c because of the picther showes
Isotopic notation for a potassium ion which has 19 protons, 20 neutrons, and 18 electrons can be correctly denoted as ³⁹K₁₉⁺¹ or ³⁹₁₉K⁺¹. Thus, the correct option is A.
What is Isotope notation?
Isotopes can also be defined in standard notation (AZE) where, A is the mass number of the atom, Z is the atomic number, and E is the symbol of the atomic element. The mass number "A" is indicated with a superscript to the left of the chemical symbol "E" while the atomic number "Z" is indicated with a subscript.
The isotope for a potassium ion which has 19 protons (atomic number), 20 neutrons and 18 electrons. A (mass number) is the sum of number of protons and neutrons in the atom. Therefore, the correct isotopic notation is ³⁹K₁₉⁺¹ or ³⁹₁₉K⁺¹.
Therefore, the correct option is A.

How do the interactions of the respiratory and circulatory systems help a multicellular organism function.Be specific and tell what organism your are explaining.
Answer/Explanation:
In humans, we breathe in oxygen via the respiratory system. The oxygen enters the lungs. The air sacs in the lungs - the alveoli - are the site of gas exchange in the lungs and are where the circulatory and respiratory systems interact.
The alveoli take in the oxygen, where it diffuses into the capillaries (circulatory system). Blood, which passes through the capillaries takes this oxygen to all the cells in the body. Oxygen binds to haemoglobin in red blood cells, which transport it around the body.
Additionally, blood also transports carbon dioxide back to the alveoli of the lungs, where it diffuses into the lungs and is expelled when we breathe out

Why is important to know about organelles?
Answer:
it helps you understand why and how a cell functions
Explanation:
Answer:
Core organelles are found in virtually all eukaryotic cells. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on. Core organelles include the nucleus, mitochondria, endoplasmic reticulum and several others.
Explanation:
Organelles are also called vesicles within a cell. And they really have a function that's important, because we need to compartmentalize all the functions within the cell. So there needs to be a membrane around the mechanisms for making a different product within a cell. So really, organelles are all membrane-bound
