You have purified the receptor for a hormone by affinity chromatography. During gel filtration chromatography under native conditions the receptor elutes between pyruvate decarboxylase (250 kDa) and glutamine synthetase (620 kDa). During SDS-PAGE, in the absence of reducing agents, the receptor migrates as a single band of approximately 230 kDa. When SDS-PAGE is carried out in the presence of 2-mercaptoethanol the receptor migrates as two bands of approximately 95 and 135 kDa. Explain this result.
Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.

1. There are 2 types of rabbits in a population: those that eat grass, and those that eat flowers and berries. One
year, a drought occurs, and the plants have a hard time producing extras such as flowers or berries. They
can only try and keep themselves green. All year the rabbits have had babies, but many get eaten by
predators like foxes and hawks. Due to the drought, though, many have also starved. Explain what type of
natural selection will occur to this population of rabbits, including what trait is selected FOR and which is
selected AGAINST, and how the population will evolve as a result of the natural selection.
Answer:
Answer:
Against: rabbits that eat berries or flowers
For: grass eating rabbits
Explanation:

Comment /free for a giveaway entry of 20 thanks and 2 brainliest. Have an awesome day! Let me know if you have any questions! -KaraYeaton18
Answer:
I'll explain it to make it easier on you :)
Explanation:
This type of natural selection is called disruptive selection. Because of the drought, foxes, hawks, and other animals eating the rabbits, the population of them is being disrupted Think of when a student is being disruptive in class. The teacher usually has to stop the class to 'punish' the student. This situation is similiar. There are things disrupting production and population of the rabbits.
FOR: The population of rabbits
AGAINST: The drought and predators
As a result of disruptive natural selection, the population of rabbits will only decrease due to predators and the drought.

true or false the typical X shaped chromosomes is the result of DNA replication
Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.

Answer: 1. In CF, the body makes abnormal CFTR protein or none at all. Without normal CFTR protein, the cells lining the pathways (tubes) inside some organs make thick, sticky mucus rather than the normal thin, watery kind. Thick mucus can trap bacteria in the lungs, leading to infection, inflammation, and breathing problems. 2. When the CFTR protein is defective, epithelial cells can't regulate the way that chloride (part of the salt called sodium chloride) passes across cell membranes. 3. Mutations in the DMD gene cause the Duchenne and Becker forms of muscular dystrophy. The DMD gene provides instructions for making a protein called dystrophin . This protein is located primarily in skeletal and cardiac muscle, where it helps stabilize and protect muscle fibers. Collapse Section. DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. 4. Lack of the dystrophin protein in muscle cells causes them to be fragile and easily damaged. DMD carriers are females who have a normal dystrophin gene on one X chromosome and an abnormal dystrophin gene on the other X chromosome. Most carriers of DMD do not themselves have signs and symptoms of the disease, but a minority do. Symptoms can range from mild skeletal muscle weakness or cardiac involvement to severe weakness or cardiac effects and can begin in childhood or adulthood. 5. Scurvy happens when there is a lack of vitamin C, or ascorbic acid. The deficiency leads to symptoms of weakness, anemia, gum disease, and skin problems. This is because vitamin C is needed for making collagen, an important component in connective tissues. 6. composed of ground substance and fibers. The extracellular matrix of connective tissue is composed of ground substance and fibers. In ordinary connective tissue, the ground substance consists mainly of water. The principal fiber type is collagen (the most abundant protein in the body), with elastic fibers as a minor element. brainliest?

Select the correct statement(s):
a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch)
b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus
c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells.
d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present
Answer:
The correct option is B Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus
Explanation:
a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch). FALSE. Olfactory information is not sent to the thalamus for its process. The rest is.
b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus. TRUE. Among the different types of tonic receptors, we may find baroreceptors, irritation receptors, tactile receptors, and proprioceptors. Tonic receptors characterize by their slow adaptation to the stimulus. The first discharge is maximal when the stimulus is received and then it progressively decreases. They send a continuous signal to the CNS.
c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells. FALSE. There are in fact three layers in the retina: photoreceptors, bipolar cells, and ganglion cell layers. NOT rod cells.
d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present. FALSE. Olfactive sense uses phasic receptors, but not continuously. These receptors shoot when they receive the stimulus, and then cease if the stimulus keeps constant.

Aquifer is the process of seeping of water under the ground.
Answer:
The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process. At places the groundwater is stored between layers of hard rock below the water table. This is known as an aquifer.
Answer:
Explanation:
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
