How would cellular respiration cause a loss in mass in the organis?

Rufina [12.5K]

Cellular respiration is the process by which living organisms convert their chemical energy from nutrients into ATP. Cellular respiration is one of the major ways by which living organisms release chemical energy to drive chemical activities. Cellular respiration cause loss in dry weight. This is because, during cellular respiration there is release of energy from the living organism, carbon dioxide and oxygen are also exchanged. The energy that has to be spent during respiration is responsible for the loss in mass in living organisms.

Few seeds can be dispersed by more than one method of seed dispersal.’ Explain with suitable examples.

MrMuchimi

Answer:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.

Gravity: A good example of gravity dispersal is the marigold flower. When they are ready, these seeds drop to the ground.

Wind: There are two types of wind dispersal adaptations, the floaters, and the fliers:

(wind) Floaters: The common dandelion is a good example of this type of seed dispersal.

(wind) Fliers: Maple seeds grow in pairs, but when they are mature, they separate, and a strong wind can pull them from the stem

Ballistic: Some common examples of this type of dispersal are garden peas. When the cells grow older, the result is that the pods break open and twist. This twisting actions pops the seeds lose and pushes them away from the pod.

Water: Coconuts have a husk that surrounds the seed. This husk is very buoyant and a coconut seed can float across hundreds of miles of ocean before washing ashore on a new island to germinate and grow into a tree.

Animals: there are also two types of these, hitchhikers and edibles. Seeds that stick to the outside of animals, or are spread when they go out the other end after being eaten:

Hitchhikers: Some examples are cockleburs and foxtail.

Edibles: These seeds are surrounded by good tasting fruit, like apples and peaches.

The bacterial transduction experiments done by Hershey and Chase, and the bacterial transformation experiments done by Griffith,

Katarina [22]

Answer:

Hershey Chase and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.

Explanation:

Both experiments have was based on different phenomenon and techniques to prove same conclusion.

Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.

Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on Streptococcus pneumonia avirulent and virulent species. By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.

Forensic scientists who study possible forgeries and questioned documents are often called what?

Ber [7]

Forensic scientists who study possible forgeries and questioned documents are often called forensic or legal linguists.
Forensic linguistics is a branch of linguistics that deals with such illegal kinds of documents so as to solve a certain crime.
