Answer: Increase the surface area.
Explanation:
The mitochondria is an important cell organelle that is found in both the plant cell and animal cell.
It basically aids in the production of ATP, hence also known as the power house of the cell.
The mitochondria is a double membrane system in which the inner membrane of mitochondria helps in increasing the surface area for integral proteins.
It helps in embedding the proteins in the folding known as cristae.
Fossils are found of giraffes with short necks.
Lamarck believed the giraffes stretched their necks and passed it to their offspring
necks grew longer due to stretching.
giraffes need long necks for food and evolution provided it to them
Answer:
Microtubules have shapes like a spindle and are arranged to form centrosome and a cluster of such microtubules form centriole.
Explanation:
Microtubules are seen in eukaryotic cells to give shape and structure to the cells and they form part of the cytoskeleton. They are known to grow long and are dynamic. Centrosomes are known to be main microtubule that are found in animal cells. They are organelles that are made from the arrangement of clusters of microtubules. The centrioles are organized microtubules that actually help to serve as skeletal system of the cell. These centrioles help to determine the locations of the nucleus.
Answer:
Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier.

hope this helps, pls mark brainliest :D
The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.
Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.
Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.
