Answer:
A germ cell
Explanation:
in order for the mutation to be passed on to future generations it must altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.
Answer:
The use of post-consumer polyolefins is increasing due to the pledges of multiple organizations to use higher concentrations of recycled materials in packaging. However, direct food contact applications are challenging with various regulations around the world mandating minimum safety requirements, which is often determined by the condition of use (microwave, cold storage) and food type (fatty, aqueous, dry). This article reviews different predictive models that have been developed to study contaminant migration from packaging to food contact articles. It also examines multiple techniques and methods that have been employed to quantify and assess to the safety of recycled materials (e.g., United States and Europe) which serve as a base for the regulatory framework for many other countries. The presence of different contaminants during polymer processing is also discussed due to potential problems from the presence of harmful compounds affecting human health or degradation of material properties.
Answer: The correct answer is option "The mechanical energy is conserved".
Explanation:
Mechanical energy = Kinetic energy + Potential Energy
Mechanical energy of the body is defined a sum of potential energy and kinetic energy possessed by the body in motion. It is the energy associated with position and motion of the body.
The principle of Conservation of Mechanical Energy states that the mechanical energy of the body remains constant as long as the forces acting on the body are conservative forces.
From, this we can say that mechanical energy of the bowling ball with mass of 2 kg falling at speed of 4.4 m/s will remain conserved.
Hence,the correct answer is "The mechanical energy is conserved".
protons boi duh dont you know your science
