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?

7 difference between Arteries, vain and capillaries
Answer: Hope this helps answer in explanation.
Explanation:
1) These are responsible for the transportation of blood from the heart to all parts of the body. These vessels collect blood through capillaries and transport it towards the heart. These vessels connect arteries and veins.
2. All arteries carry oxygenated blood except pulmonary arteries which carry deoxygenated blood. All veins carry deoxygenated blood except pulmonary veins which carry oxygenated blood. These carry mixed oxygenated and deoxygenated blood.
3. Arteries have no valves in them except at the base of the pulmonary trunk and aorta. Valves are present in veins. These valves prevent the backflow of blood. There are no valves in them.
4. Arteries have high blood pressure. Veins have low blood pressure. There is falling pressure in them.
5. In arteries, waves of blood pressure or pulse due to heartbeat can be detected. There is no pulse. There is no pulse.
6. Blood flows rapidly between 400-500mm per second in the aorta and decreasing in arteries and arterioles. The rate of blood flow increases from smaller to larger veins. Blood flow is slowest which is less than 1mm per second.
7. Arteries have a smaller bore and thick walls. Veins have a larger bore and thin walls. Capillaries have a larger bore and the wall is of one cell in thickness.
8. There are thick muscle layers and elastic fibers present. The elasticity helps to change the pulsating flow of blood. There are thin muscle layer and less elastic fibers present in veins. So, they are less elastic. No muscles or elastic fibers are present.
9. There is no exchange of materials. There is no exchange of materials. These are responsible for the exchange of gases and nutrients.

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.

Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary tube as the temperature rises. Suppose a mercury thermometer contains 3.380g of mercury and has a capillary that is 0.200mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0 0C to 25.0 0C
Answer:
3.5 cm
Explanation:
Mass of mercury = 3.380
Diameter = 0.200
At t = 0 and 25 degrees we have 13.596 and 13.543 as density
At 0 degree = v = 3.380/13.596 = 0.2485
At 25 degrees = 3.380/13.534 = 0.2497
We use volume of cylinder to get height
At 0⁰ height = 7.91
At 25⁰ = 7.944
The difference in height = 0.035
Multiply by 100 = 0.35 x100
= 3.5cm

Why do you think that the shape of the different types of fatty acid molecules affects how easily they solidify?
Answer:
Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses.
Lipid molecules consist mainly of repeating units called fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Both types consist mainly of simple chains of carbon atoms bonded to one another and to hydrogen atoms. The two types of fatty acids differ in how many hydrogen atoms they contain.
Explanation:
Can I plz have brainliest
The shape of the types of fatty acid molecules has an impact on their solidification.
It should be noted that in the unsaturated fatty acid, there is at least a double bond in its string. The carbon atoms that are joined by the bonds lead to the change in their shapes.
While saturated fatty acids have a linear structure, the unsaturated fatty acids kink or bend in order to form double bonds within the chemical foundation.

For humans, linoleic acid is one of the essential fatty acids we must consume. It is plentiful in vegetable oils, and we use it to form compounds involved in immune responses. When it is decomposed through a process called b-oxidation, it produces effectively 27 NADH, 9 FADH2 and 9 ATP in the Krebs cycle, along with 9 FADH2 and 9 NADH as part of the decomposition.
Required:
How many ATP should this produce?
Answer:
18 ATP.
Explanation:
Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from 9 FADH2 so total it produces 18 ATP molecules.

Answer and Explanation:
When mRNA leaves the nucleus and meets a free ribosome in the cytosol, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.
Ribosomes attached to the RER membrane are responsible for synthesizing membrane proteins, exportation proteins, or enzymes.
The synthesis of proteins destined to become enzymes, membrane proteins, or exportation proteins starts in the cytoplasm with the production of a molecule portion known as a signal aminoacidic sequence. This signal sequence in the amino extreme of the synthesizing protein, and when it reaches a certain length, it meets the signal recognizing particle that leads the synthesizing protein and associated ribosome to the Rough endoplasmic reticulum, where it continues the protein building until finishing the elongation process. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen, suffering a few posterior steps related to conformation and structure, such as folding to become functional and the initial glycosylation stages.
The new proteins get packaged into vesicles that carry them to the Golgi complex where occurs the final association of carbohydrates and lipids with proteins, to originate glycoproteins and glycolipids.
Enzymes destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles. When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.
As mercury moves up the trophic levels in food chains, its concentration
Stays the same
Increases
Decreases
Is eliminated
Answer:
Increases
Explanation:
The concentration of mercury will increases as it moves up the food chain because of biomagnification. For example, a school of small fish consumes a minute amount of mercury each, but then a larger fish eats five of the smaller fish. After this the larger fish has more mercury in its system than one small fish because it ate five small fish (along with the mercury in each of the small fish). Now a seal eats multiple large fish. Overall, the seal has the highest mercury concentration out of all the animals mentioned.
Biomagnification is "the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed."
why is protein synthesis diffrent in prokaryotes and eukaryotes?
Answer:
In prokaryotes, translation occurs in the cytoplasm, where the large and small subunits of the ribosome bind to the mRNA. In eukaryotes, translation occurs in the cytosol or across the membrane of the endoplasmic reticulum where the entire ribosome/mRNA complex binds to the outer membrane of the rough endoplasmic reticulum and the new protein is synthesized and released into the ER; the newly created polypeptide can be stored inside the ER for future vesicle transport and secretion outside the cell, or immediately secreted.
