personwith kleinfelter's syndrome?

Answers

Answer:

• Men with Klinefelter's syndrome have an extra X chromosome.

• Of the 23 pairs of chromosomes, one pair is called the sex chromosomes because they determine a person's sex. One sex chromosome is inherited from the mother and the other from the father. Mothers always pass on an X chromosome, but fathers can pass on an X or a Y chromosome. -

•The normal male chromosome arrangement is 46XY, but men with Klinefelter's syndrome have 47XXY. The extra X chromosome can come from either parent.

Which characteristic do euglenoids and algae share

Answers

Euglenoids are unicellular protists commonly found in fresh water.They don not have a cell wall, despite that, a protein rich cell membrane called pellicle is present in Euglenoids.
Whereas,Algae are eukaryotic organisms comprising of no roots, stems, or leaves but they filled with chlorophyll and other pigments to carry out the process of photosynthesis. Similar to Euglenoids, they occur most frequently in water, specifically in plankton.
Hence,
Euglenoids and algae share a common characteristic,that is both are autotrophs. They produce complex organic compounds from simple substances present in their surroundings, by the use of energy from sun-light or inorganic chemical reactions.

This is a process where two nuclei or particles interact to form different particles

Answers

Answer:

Nuclear Reaction

Explanation:

When two nuclei or particles move towards each other and, despite the Coulomb repulsion, they get close enough that there is interaction between the particles of one with the particles of the other by the nuclear force, and the formation of different particles and a redistribution of nucleons and a nuclear reaction is said to have occurred.

Nuclear reactions are usually produced by bombarding a target nucleus with a projectile that may be some type of particle or small nucleus, so that Coulomb's repulsion does not become a major obstacle. Reactions involving not very large energies occur in two phases. In the first phase, the target nucleus and the projectile group together, forming what is called a compound nucleus in a highly excited state. In the second phase, the composite core decays by any process that does not violate the conservation principles

In nuclear physics, a nuclear reaction is a process in which two nuclei or nuclear particles collide, to produce different products than the initial particles. In principle a reaction can involve more than two particles colliding,
