I think it is the somatic nervous system.
A.
Animal cells are very close to plant cells, but they have one key difference that separates them; the cell wall.
A cell wall is a thicker layer on the outside of the cell membrane. These are unique, and are <u>only found in plant cells.</u> Animal cells just have the cell membrane as their outer part. This enables them to change shape due to the membrane being very flexible.
Plant cells do not change, and only conform to their cell wall's shape. This enables them to grow up (literally) to help gather sunlight and enable photosynthesis.
Saturated fat is typically solid at room temperature.
Answer:
The weakest part of a long developing and adolescent bone is called growth cartilage (epiphyseal plate)
Explanation:
Both children's bones and adults' bones are at risk of injury. However, in the case of bones in a child, they are subject to an injury known as a growth cartilage fracture or epiphyseal plate. These growth cartilages are areas that are in full development in the vicinity of long bones. Its function is to help establish the length and shape of the bone in the process of maturation. The growth of a long bone happens from the end next to the growth cartilage. In adulthood, these growth cartilages are strengthened forming the bone.
The right answr is hydrogen bonds
The hydrogen bond or hydrogen bridge is an intermolecular force involving a hydrogen atom and an electronegative atom such as oxygen, nitrogen and fluorine. The intensity of a hydrogen bond is intermediate between that of a covalent bond and that of van der Waals forces.
The helices of the DNA (both strands) are maintained by hydrogen bonds.
