Answer: Micro villi
Explanation:
The cellular structures that increases the superficial surface area of the cell is known as micro villi. It is an extension of cell membrane.
This structure helps in the increasing the surface area for the maximizing the absorption of food materials.
It also helps in providing a large area in a very compacted space. It is found at many places in the human body such as in small intestine.
The correct answer is B. Protection and dispersal of seeds
Explanation:
In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.
Answer:
Our Genetic Code all use for example in You and I use ATGC and so would a Dogs DNA.
Explanation:
Thats the reason it looks similar we have the same building blocks. But when we arrange the letters in diffrent order is where our gentetic diversity comes from. The only slight diffrence is in RNA because it uses AU instead of AT

Answer:
Seismographs record seismic waves. They contain a weight and a pen attached to a spring. The seismograph is bolted to the ground so during an earthquake it moves with the ground, whilst the weight and pen remain still. The pen moves across a rotating paper roll recording the seismic waves.
Hope this helped, have a good day
