What has nuclear dimorphism?

What has nuclear dimorphism?

Paramecium, like other ciliates, is characterized by nuclear dimorphism, which is the presence of two types of nuclei with distinct organization and functions in the same cytoplasm.

In which of the following the nuclear dimorphism is seen?

Paramoecium is a ciliated protozoan that is known to show the nuclear dimorphism due to the presence of two different types of nuclei within the cell.

What is the function of micronucleus?

The micronucleus is a storage site for the germline genetic material of the organism. It gives rise to the macronucleus and is responsible for the genetic reorganization that occurs during conjugation (cross-fertilization).

What is monomorphic nuclei?

monomorphic –> monomorphous. (Science: biology) Having but a single form; retaining the same form throughout the various stages of development; of the same or of an essentially similar type of structure; opposed to dimorphic, trimorphic, and polymorphic.

Is Dengue related to malaria?

Both diseases can cause acute febrile illness. However, malaria can be chronic while dengue cannot. The specific triads of dengue, atypical lymphocytosis, hemoconcentration and thrombocytopenia might be a clue for differential diagnosis of dengue infection from other tropical infections including to malaria[7]–[9].

Is dengue caused by virus?

Dengue is a mosquito-borne viral disease that has rapidly spread in all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae.

What is the symptoms of malaria and dengue?

Some people who have malaria experience cycles of malaria “attacks.” An attack usually starts with shivering and chills, followed by a high fever, followed by sweating and a return to normal temperature. Malaria signs and symptoms typically begin within a few weeks after being bitten by an infected mosquito.

What is the difference of malaria and dengue?

Malaria is caused by a female mosquito, Anopheles; while dengue is caused by Aedes aegypti mosquito. In the past, the presence of a co-infection in an individual is sporadically reported [1, 2]. Both of the diseases cause an acute pyrexial illness; however, only malaria can cause a chronic fever.

How many humans have died from malaria in history?

Over millennia, its victims have included Neolithic dwellers, early Chinese and Greeks, princes and paupers. In the 20th century alone, malaria claimed between 150 million and 300 million lives, accounting for 2 to 5 percent of all deaths (Carter and Mendis, 2002).

How many mosquitoes does it take to kill a human?

For an average person, losing two liters of blood becomes life-threatening. The average mosquito bite drains 0.01 to 0.001 milliliters of blood. Thus it would take somewhere between 200,000 and 2 million mosquito bites to kill you from blood loss.

Does Germany have malaria?

For 2018, 8 349 malaria cases were reported in the EU/EEA, 8 347 (> 99%) of which were confirmed. France reported the highest number of cases, followed by the United Kingdom and Germany (Table 1, Figure 1). The overall notification rate was 1.2 cases per 100 000 population, the same as in 2016 and 2017.

Why does Africa have more malaria?

The costs of malaria – to individuals, families, communities, nations – are enormous. Malaria occurs mostly in poor, tropical and subtropical areas of the world. Africa is the most affected due to a combination of factors: A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission.
