I cannot find the propositions, so I just define what an alpha particle is:
Alpha particles (or alpha rays) are a form of radiation emitted by unstable nuclei of great atomic mass (alpha decay). They consist of two protons and two neutrons combined into a particle identical to the helium nucleus, so they can be written 4He2+ (or 4α2+). (the nuclei will lose 2 positive charges and 4 atomic masses)
Unlike other particles, a Beta particle is the emission of an electron (or a position), and gamma rays (not a particle) is the emission of a ray photon very high energy light.
I hope this could help you with you answering the question.
Answer:
The correct list is inner core, outer core, lower mantle, asthenosphere, lithosphere.
Explanation:
Based on Structural features and chemical composition earth surface is divided into different layers. The main layers can be described as,
1. Core
2. Mantle
3. Crust
Core:
The core is further divided into inner core and outer core. The inner core is extremely hot and solid. The outer core is in fluid form and surround the inner core.
Mantle:
The mantle layer is composed of rocks. The earth's mantle is also divided into two main layers Lower mantle and upper mantle. Asthenosphere is viscous and present just below the rigid lithosphere.
Crust:
Crust is the outermost layer of earth. It is composed of variety of elements. Lithosphere is the part of Crust.
Because the black mouse is homozygous.
The black color in mouses is dominant, and the brown is recessive. When a parent is homozygous, their children need to have their gene. Because in this case the trait is black, it dominates brown in all children.
The table is BB×bb = Bb, Bb, Bb, Bb = 100% heterozygous genotype = 100% black phenotype.
Answer:
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes
