Answer:
chemicals have been released into the organism as the genes/DNA have been altered.this protects the crop from pests and harsh weather.
the altered genes also make the nutritional value soar so the value of the plant is good.
some may disagree with this as the genes could cause unknown side effects and it harms local wild life
Explanation:
Phospholipids form a bilayer in water because of the shape and amphipathic nature of the lipid molecules
Phospholipids are a class of lipids, it are a major component of all cell membranes. Phospholipids are the shape and amphipathic nature of the lipid molecules that cause them to form bilayers spontaneously in aqueous environments. The most abundant membrane lipids are the phospholipids.
Phospholipids form a bilayer in water because of the shape and amphipathic nature of the lipid molecules. Phospholipids shape are cylindrical and the phospholipid molecules spontaneously form bilayers in aqueous environments. All of the lipid molecules in cell membranes are amphipathic. Amphipatic is the condition where phospholipids have a hydrophilic (water-loving) or polar end and a hydrophobic (water-fearing) or nonpolar end. The structure of the phospholipid molecule consists of two hydrophobic fatty acid "tails" and a hydrophilic "head". Phospholipids arrange themselves into two parallel layers called a phospholipid bilayer. The lipid bilayer or phospholipid bilayer is a thin polar membrane which is made of two layers of lipid molecules. This layer makes up the cell membranes and is critical to the ability of cell's function.

Phospholipids form a bilayer in water due to their amphipathic nature, with hydrophilic heads facing out and hydrophobic tails facing each other. This lipid bilayer acts as a barrier in the plasma membrane, separating materials on either side. Structures such as micelles, liposomes, and lipid-bilayer sheets are formed by phospholipids in water.
Phospholipids form a bilayer in water because of their amphipathic nature. The polar heads of phospholipids are attracted to water molecules, while the nonpolar tails are not. This leads to the arrangement of phospholipids with their hydrophobic tails facing each other and their hydrophilic heads facing out, resulting in the formation of a lipid bilayer.
This bilayer structure is essential for the plasma membrane as it acts as a barrier, separating the water and other materials on one side of the membrane from the water and other materials on the other side.
Examples of structures formed by phospholipids in water are micelles, liposomes, and lipid-bilayer sheets, which are the structural basis for cell membranes and various subcellular components.

Answer: Kira has difficulty in walking in smooth coordinated manner because she has suffered injury to the cerebellum.
Explanation:
Cerebellum is a part of the brain situated inferior to cerbrum and posterior to pons. It receives sensory information and converts it into motor responses. Motor coordination is when subsequent parts of the same movement, or the movements of several limbs or body parts are combined in a manner that is well timed, smooth, and efficient. Cerebellum coordinates voluntary motor movements resulting in smooth coordinated muscular activities. Injury to cerebellum causes its loss of function which in return causes
1) loss of coordinated movements
2) inability to perform alternate rapid movements
3) movement tremors
4) staggering wide based gait
Kira likely damaged her cerebellum, as this part of the brain regulates fine motor control and coordination. Damage can lead to ataxia, characterized by unsteady, uncoordinated movements.
After suffering a brain injury and having difficulty walking in a smooth, coordinated manner, it's likely Kira has suffered damage to her cerebellum.
The cerebellum is part of the brain responsible for fine motor control, balance, and coordination. Damage to this area can result in ataxia, a type of movement disorder characterized by a lack of muscle control during voluntary movements, leading to unsteady and uncoordinated walking.

Answer: Mutation
Explanation:
A mutation is a random change in a cell's genetic code due to a variety of causes. The change can be small and insignificant, or it can be major. Mutations can be passed onto offspring through reproduction, thus increasing the genetic variation within a population.
Answer:
Metaphase
Explanation:
Metaphase is the phase of mitosis that starts with complete disintegration of nuclear envelop. It is marked by attachment of spindle fibers to the kinetochores of chromosomes and movement of chromosomes to the middle of the cell, that is, equator. Chromosomes are aligned along center of the cell through spindle fibres .
