PLEASE HELPPPfrom the illustration above classify #1
a: bird
b: fish
c: amphibian
d: insect
e: mollusk
f: mammal
g: reptile
h: none of these

Answers

The classifications of the below-illustrated organisms are as follows:

  • #1 = Reptile.
  • #2 = Mammal.
  • #3 = Bird.
  • #4 = Amphibian.

What are the characteristics of Reptiles?

The characteristics of reptiles are as follows:

  • They perform locomotion through crawling or creeping mode.
  • They are mostly terrestrial animals.
  • Their body is covered by dry and cornified skin.
  • They do not possess external ear openings.
  • Their heart is typically three-chambered, but exceptionally crocodiles have a four-chambered heart.

Mammals are mammary glands in order to feed their young ones. Amphibians have the ability to live in both water and terrestrial habitats. They have two pairs of limbs. The Body is divisible into the head and trunk.

Birds are classified into the category of Aves. The presence of feathers is one of the most important characteristics of this type of classification.

Therefore, the classifications of the below-illustrated organisms are mentioned above very briefly.

This is a typical grassland food web. It is also a small picture of an important cycle on Earth: the carbon cycle. Describe how the carbon gets into this food web.a. Bacteria and fungi, the decomposers, recycle carbon from dead organisms.
b. Carbon is found in the grass and is passed from one level to the next in this food web.
c. All living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere.
d. Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

Answers

The correct answer is letter d. Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar. In a typical grassland foodweb, carbon is used by plants (carbon dioxide) to create food for themselves. 

Answer:

The correct answer would be option D.

In any food web, the inorganic carbon from the atmosphere is incorporated into the organic matter by the process of photosynthesis.

Autotrophs perform photosynthesis and fix carbon obtained from carbon dioxide into the glucose or organic matter with the help of chlorophyll and in the presence of sunlight.

Which of the following structures are used by prokaryotes for attaching to surfaces?a. capsule
d. nucleoid

Answers

The structure used by prokaryotes for attaching to surfaces is Capsule.

RoleofCapsuleinprokaryotes

Capsules are known to be the sticky outermost layer made up of polysaccharides.

Their role in prokaryotes include:

  • Aid prokaryotes to cling to each other.
  • Allows prokaryotes to attach to surfaces in their environment
  • Helps in preventing prokaryotic cell dehydration.

Therefore, the structure used by prokaryotes to attach to surfaces is the capsule.
