An organism must has a large surface area to volume ratio in order to exchange material easier
in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel
multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange
the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio
hope that helps
Answer:
forced people to improve their morals.
Explanation:
The prohibition prevent people from consuming alcohol , which is dangerous for their health and overall well-being so it is automatically improving the morals of the people by forcing people not to consume alcohol. This question refers to the law that 'prohibited' people from consuming alcohol, since it is not an awareness campaign but a law that tried to improve the morals of the people so it is a <u>Noble experiment</u>.
Answer:
Heredity
Explanation:
It is Heredity because the word genetics means the study of Heredity.
For Anna’s case, my preliminary idea of the species of bacteria
responsible for Anna’s infection is a Gram-negative bacterium as observed in gross examination of the
colony. With this, my <span>idea has not changed since the last activity for the bacteria was
rod-shaped when we view it through a
microscope and the color of the colonies was
pink after we Gram stained it, which indicate that it is Gram-negative.</span>
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.
