Cystic fibrosis is a genetic mutation. It is one of the most common genetic diseases in the world. There is no cure for CF.
Answer:
hello your question lacks the required options
Group of answer choices
It allows the animal to consume a second meal while the first is being digested.
It permits development of specialized enzymes and concentration of digestive juices in different regions.
It permits more time for enzymatic action.
Additional physical cutting and grinding of the food bolus is made possible.
All of the above are advantages
answer : All of the above are advantages
Explanation:
An animal with a gastrovascular cavity has some advantages over the animal with a tube-type digestive system . a gastrovascular cavity allows for the digestion and transport of nutrients across the body and is found in phyla and Platyhelminthes
The major advantages the gastrovascular cavity has includes :
It allows the animal to consume a second meal while the first is being digested.
It permits development of specialized enzymes and concentration of digestive juices in different regions.
It permits more time for enzymatic action.
Additional physical cutting and grinding of the food bolus is made possible.
The responses observed in type IV hypersensitivities result from the action of T cells and phagocytes.
Hypersensitivity IV type, also called delayed-type hypersensitivity (DTH), involves T cell-antigen interactions that cause activation and secretion of cytokines. This type of hypersensitivity requires sensitized lymphocytes that respond 24–48 hours after exposure to soluble antigens. A type IV hypersensitivity reaction is a cell-mediated reaction that can occur in response to contact with certain allergens, resulting in what is called contact dermatitis, or in response to certain diagnostic procedures such as the tuberculin skin test. Certain allergens need to be avoided to treat this condition. Type IV hypersensitivity response is observed results from the action of T cells and macrophages while other types are mediated by antibodies. This reaction occurs at least 1–3 days after the initial exposure. Type IV hypersensitivity is the mechanism of many autoimmune disorders.

B. a cell with two distinct nuclei
Telophase is the last phase of mitosis and then cytokinesis
The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.
- The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
- With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
- All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
- While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.
