Answer:thomas malthus

Explanation:

Malthus stated that man is also capable of overproducing if left unchecked. He concluded that unless family size was regulated, man's misery of famine would become globally epidemic and eventually consume him. Malthus' view that poverty and famine were natural outcomes of population growth and food supply was not popular among social reformers who believed that with proper social structures, all ills of man could be eradicated.

Describe the actual and relative sizes of a virus, a bacterium, and a plant or animal cell.
anzhelika [568]

Answer :

The animals are categorized into 2 groups - eukaryotes and prokaryotes. The microbes like bacteria are coming under prokaryotes. They are unicellular organisms and without a true nucleus.

Viruses are the connecting link between the living and non - living. They are smaller than bacteria. The microbes less than 100 micrometer can't be seen by the naked eye. They can only visible under a microscope.

Viruses like polio, flu virus sizes are 10nm. But some of the viruses are also less than 10nm. The size of bacteria is 1 micrometer. The viruses are 10 times smaller than the bacteria.

The eukaryotic organisms are more advanced and multicellular. Their cell size is larger than bacteria and viruses. The red blood cells under the light microscope are 8 micrometers. The typical animal cells like sperm are 60 micrometers and a skin cell is 30 micrometers. The plant cell for example pollen is 90 micrometers.

The eukaryotic cells sizes are more than prokaryotes like bacteria.

Need Help!! Read the article “Tweaking How Plants Manage a Crisis Boosts Photosynthesis,” and then answer the following question
agasfer [191]

Answer:

A plant’s ability to photosynthesize depends on a variety of factors, including the amount of available sunlight. Plants also go into a protective mode after an environmental crisis, which helps protect the plants’ chloroplasts from damage. During this period, photosynthesis is low. The technique used in this research improved the plants’ ability to recover after a crisis, boosting plant growth and crop yield. This research could ultimately lead to growing crops successfully in different types of environments and in a shorter period of time.
