Another crab is discovered. scientists find that it is able to mate and reproduce fertile offspring with the dungeness crab. to what genus and species must this other crab belong?
The other Crab belongs to Genus-Cancer and Species-Magister.
The Dungeness crab, also known as Cancer magister or Metacarcinus magister, lives in bays, estuaries, and along Alaska's nearshore coast. Named after a narrow, sandy inlet within Dungeness Spit on the southern border of the Straits of Juan de Fuca, the species is named for one of its characteristic habitats. When female living Dungeness crabs are ready to molt, they lose their exoskeleton to enable them to grow and produce a larger shell; this is the ideal time for mating before the new, hard shell has developed.
The family Cancridae includes the genus Cancer of saltwater crabs. Eight of the species are still living, while three have already gone extinct. Among them are well-known littoral zone crabs like the red rock crab, the Jonah crab, and the European edible crab.

Why is the level of water vapour variable in inhaled air
The level of water vapor variable in inhaled air due to the factors like difference in the temperature, and availability of water to evaporate.
Why is the level of water vapor variable in inhaled air?See the amount of water vapor present in the atmosphere is called humidity which have already studied in earlier classes well.Now we cannot expect the water vapor to be constant as it varies from environment to environment , and temperature to temperature.Actually water vapor is variable which means its amount in air at any one place in troposphere is not fixed.We inhale air present in the atmosphere , and it is absolutely not necessary to have the air which contain water vapor.So the amount of water vapor present in the atmosphere is a variable and not a constant.To know more about water vapor visit:

cell cycles
Asexual reproduction describes budding, fission, and regeneration.
Budding, fission, and regeneration are types of asexual reproduction seen in lower organisms like bacteria, fungi, and algae. Asexual reproduction results in the production of clones or daughter cells that are identical to each other and the parent cell. Budding is specifically found in yeast. Fission is found in bacteria. While regeneration is found in animals like planaria and hydra.
What is the specialty of Asexual reproduction?
Asexual reproduction refers to a type of reproduction where a child is born to a single parent. The newly created people are clones of their parents since they have the same genetic makeup and physical characteristics. Both multicellular and unicellular species can reproduce asexually.

What do you mean by offspring?
The young creation of living organisms, known in biology as progeny, can be created by a single organism or, in the event of sexual reproduction, by two organisms. A group of offspring is sometimes referred to as a brood or progeny in a more generic sense.
The gene drive technology, based on CRISPR incorporated in the native chromosome, is used to alter a species by eliminating certain character and introducing a good one, here gene preventing malaria. The key components are CRISPR, Cas9 and a gene of interest (gene preventing malaria). The mechanism involves cutting of the native chromosome at the required site followed by coping the drive sequence as happens in homologous repair. So, the gene causing malaria is inactivated. This character is passed to the next generations. If this is introduced in maximum individuals, after 15-16 generation we can see the gene preventing malaria present in all individuals.

The process of making platelets, which are anucleate, small (2 to 4 m). They're round to ovoid cells found in blood arteries, is referred to as thrombopoiesis.
The process through which thrombocytes are produced is known as thrombopoiesis. Cells called thrombocytes are crucial for blood clotting. Thrombocytes are also referred to as platelets in mammals. Although they also take part in secondary hemostasis (coagulation) and inflammatory pathways, platelets play a key role in primary hemostasis. The main factor controlling thrombopoiesis is thrombopoietin (Tpo). Tpo is continuously produced by the liver and renal tubular epithelial cells, and it is then excreted and eliminated by platelets and their forerunners during thrombopoiesis. As a result, the relationship between platelet and platelet precursor mass and plasma Tpo concentration is inverse.

What is least characteristic of the pharyngeal tonsils?
The least characteristic of pharyngeal tonsils is the tonsils that are most commonly removed by tonsillectomy.
The entry of the nasal cavity into the pharynx is where the pharyngeal tonsils are located. Adenoids are the name for these tonsils, which can block breathing when they expand. The palatine tonsils are located close to the pharyngeal opening where the oral cavity enters.
The respiratory epithelium lines the pharyngeal tonsil but stratified squamous epithelium lines the lingual tonsil and is placed near other structures within the tongue (e.g., salivary glands), which helps to identify it from the palatine tonsils.
The pharyngeal tonsils are also known as adenoids and they guard against infections and cleanse out harmful particles.
Colds, throat irritation, and sore throats can still occur after tonsillectomy. However, one will not acquire tonsillitis (enlarged pharyngeal tonsils) until the tonsils regenerate, which is unlikely.
