Answer:
Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation 
(Energy equals mass times the speed of light squared).
He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation .
The pedigrees have not been provided. They have been attached.
Answer:
Pedigree 1 : Autosomal recessive
Pedigree 2 : Autosomal dominant
Pedigree 3 : Autosomal recessive
Explanation:
It has been given that the traits are autosomal i.e. they are not controlled by X and Y genes. We have to further find out if they are inherited in recessive pattern (autosomal recessive) or in dominant pattern (autosomal dominant).
Pedigree 1: Out of the three generations, the trait is only observed in one. This usually happens in recessive inheritance as two recessive alleles must be together to express the condition and this event has less chances of occurring. Also, it is visible how normal parents in first generation had a daughter with the recessive trait. This is possible if the parents were heterozygous for the trait or "carriers". They contributed one recessive allele each in the next generation due to which the daughter showed the recessive phenotype. Thus, this is most probably a recessive condition.
Pedigree 2: Out of the four generations, the trait is expressed in three. This usually happens in dominant inheritance as only one allele is needed to express the trait so both dominant homozygous and heterozygous individuals will show it. Thus, this is most probably a dominant condition.
Pedigree 3: This trait also skipped generations which is a feature of recessive traits. As with pedigree 1, the trait disappeared in pedigree and reappeared when two recessive alleles came together again. Thus, this is most probably a recessive condition.
Answer: Five
Each pond or lake have typically five zones in common.
1. The littoral zone: It is the shore area of the pond or lake. It is a transition zone between the dry shore area and the open water.
2.The limenetic zone: It is the open water area of the lake or pond. This is the portion of water that receives sunlight light.
3.The euphotic zone: It is the zone where, algae and other plants grows. Also, this zone favors the growth of aquatic animals such as fishes, because oxygen levels are higher as this zone traps the atmospheric oxygen.
4. The profundal zone: It is the zone located below the limentic zone. This zone is not penetrated by sunlight. The size of the zone depends upon the age and water clarity of the pond or lake. It exhibit low fish and plant population because of the lack oxygen present in this zone.
5. The benthic zone: It is the zone which is found at the bottom of the lake or pond. It consists of organic sediments and soil. This zone involves decomposition activity of the dead organic matter obtained from dead algae, plants, fish and animal wastes.
It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. The genetic or chromosomal abnormality that is correctly matched with its description is this: Phenylketonuria—the child cannot produce a critical enzyme, resulting in an accumulation of <span>poison, in turn causing mental disorder. Hope this helps.</span>
