Answer:
maternal and paternal chromosomes sort independently
Explanation:
Alleles for a gene are present on a particular locus on homologous chromosomes. Meiosis includes the pairing of homologous chromosomes and their segregation of opposite poles. One member of a homologous pair is paternal and the other is inherited from mother.
The random arrangement of homologous chromosomes at the equator of the cell during metaphase I result in independent segregation of paternal and maternal chromosomes to opposite poles during anaphase I. This leads to new combinations of traits in the progeny which were otherwise not present in either parent.
Answer:talk about how fascinating Nature is in all of the good qualities it’s good to preserve nature for animals and to make the world last longer with things like pollution and go on from there
Explanation:
5 m. How fast does it travel through the water?
Answer:
10m/s
Explanation:
Given parameters:
Frequency of wave = 2Hz
Wavelength = 5m
Unknown:
Speed of the wave = ?
Solution:
The speed of a wave is derived from the product of wavelength and frequency;
speed = frequency x wavelength
Insert the parameters and solve;
speed =2 x 5 = 10m/s
B. Mutation
C. Independent assortment
D. Random fertilization
E. All of the above
Answer:
The correct answer is E. All of the above
Explanation:
Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.
During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.
Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.
Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
Solids have the least amount of energy among the four physical states of matter because their particles are held tightly together and can only vibrate, possessing less thermal energy than in the liquid, gas, or plasma states.(Option D)
The correct statement about the energy level of solids is that solids have the least amount of energy among the four physical states of matter. In a solid, the atoms or molecules are held close together by strong intermolecular forces, which significantly restricts their ability to move. As a result, the particles can only vibrate about fixed positions, and this vibrational motion accounts for the thermal energy in solids.
This is less energy than the particles have in liquid, where they can move freely but are still close together, and much less than in gas, where the particles have enough energy to break away from one another and fill the available space. In plasma, which is an ionized state with even higher energy, particles have the most energy compared to the other states of matter.
