Overwhelming scientific evidence suggests that all living things share acommon *

ancestor
cell type

energy source
cell structure

Answers

Answer 1
Answer: The answer is ancestor.

Energy source is incorrect, as plants function through photosynthesis unlike animals. Different organisms also have different types and structures of cells. Plant cells for example, are much different than that of an animal.

How the metabolism of hetero trophy differs from that of autotrophs

Answers

In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web.   



The options in the question contain both autotrophs and heterotrophs.
(a) A giant redwood tree = Autotroph
(b) A spider = Heterotroph
(c) A rose bush = Autotroph
(d) A mushroom = Heterotroph
(e) A blue whale = Heterotroph
Autrophs are the organisms that have the capacity to form their own food from inorganic substances like the carbon dioxide. 
Heterotrophs are the organisms that cannot produce their own food but depends on other animals or plants for their nutritional needs.

Answers

Inna finds an unique fossil in her backyard along with a fossilized tooth. Fossils of bones, teeth, and shells have actual physical remains. So, the correct options for 1, 2, 3, 4, 5, 6  and 7 are D, (C, D and E), D, B, (C, D and E) ,D and D respectively.

What are Fossils?

Fossils are the fossilized remains of organisms that have been supplanted by rock material, including traces of species like bacteria, fungus, and single-celled organisms. The remains or evidence of prehistoric life that has been preserved through natural processes are known as fossils.

Shells, teeth, and bones are examples of fossilized organic matter. Scavengers are prevented from devouring organism remains by rapid burial. Fossilization requires stable geologic conditions. We can learn about former species' potential evolution, ages at death, and life cycles from their fossils. The best proof that a region once experienced a tropical environment is insects trapped in amber. Burrows in a sedimentary rock bed indicate that dinosaurs formerly inhabited the area.

Therefore, the correct options for 1, 2, 3, 4, 5, 6  and 7 are D, (C, D and E), D, B, (C, D and E) ,D and D respectively.

How can scientists use this information to develop new treatments for these diseases?Based on your findings,do you think that scientists will need to develop multiple treatments to control symptoms of these diseases?

Answers

Answer: Scientists research focuses on science related to the immune system and human genetics, while leveraging advanced technologies including functional genomics, artificial intelligence and machine learning – all of this is driven by the multiplier effect of Science x Technology x Culture.

Explanation: It’s important to learn about diseases because Rare diseases can provide valuable insights into the causes and progression of far more common diseases. The study of these diseases can also lead to the development of life-saving drugs

What characteristics are common in angiosperms

Answers

The characteristics that are common in angiosperms are flowering plants that have seeds covered under fruits.

What are the characteristics common in angiosperms?

  • Angiosperms are flowering plants that have seeds covered under fruits.
  • These are eukaryotic, multicellular, and non-motile living organisms.
  • These are land plants that have diverse habitats.
  • Their plant body is divided into roots, stem, and leaves.
  • They have a well-defined vascular system consisting of xylem and phloem vessels.
  • Secondary growth is seen in angiosperms.
  • These can be annual or perennial, evergreen or deciduous, and woody to herbaceous. These consist of herbs, shrubs, and trees.
  • Angiosperms vary in size, from duckweed being the smallest one to Eucalyptus being the tallest one.
  • The sex organs are found inside the flower.
  • The stamen consists of a filament and anthers, while the carpel comprises stigma, style, and ovary.
  • Angiosperms have unique double fertilization.
  • The life cycle of angiosperms shows an alternation of generation.
  • The sporophyte phase is dominant, while the gametophyte phase is reduced.
