There are small individual fibres in the muscles, known as musclular fibres or muscle fibers that iat the same time are formed by myofibrils.
The most common and accepted theory of how muscles contract is the sliding filament theory:
The theory says that neurons send signals to the muscle fibres, and, inside these, actin and myosin bind with each-other, contracting themselves using ATP as an energy source. That is a simple way of describing how muscle contraction occurs.
The image down below may help you understand the sliding filament concept a bit better.
Hope it helped,
Happy homework/ study/ exam!
Answer:
The correct answer will be- Chimera
Explanation:
A chimera is an organism which is composed of cells with different genotypes.
The genetic chimera is produced during the formation of the transgenic organisms mainly animals when every cell of the growing embryo does not receive the introduced genes. This results in the formation of two or more zygotes which when merged form genetic chimera.
Thus, a chimera is the correct answer.
There are many different types of technology used for farming. such as, fertilizers, pesticides, genetic engineering, and hormones.
