Hey there!

There are about 20 different amino acids in proteins. They can be made up of hundreds of acids. It is not really the type of amino acid that tells one cell from another, but the<em> order or combinations </em> the acids come in, which helps to define each cell. This is most important, remember that,<em> order</em>.

Hope this helps!

To be injured by an animal with poisonous spines, you must: be the aggressor and touch the animal first.

<h3>What is the use of spines in animals?</h3>
  • Spines are hard, needle-like anatomical structures found in both vertebrate and invertebrate species.
  • The spines of most spiny mammals are modified hairs, with a spongy center covered in a thick, hard layer of keratin and a sharp tip.
  • Spines on an animal’s body help defend it.
  • They can be irritating or painful, or difficult to swallow.
  • Spines are also important tools for communication, shock absorption, and rain protection.
  • Animals like porcupine shoot their spines (quills) for defense. Some spines can also pass through gloves.

Edwin Hubble used the Doppler effect to determine that the universe is expanding. After years of scientific research and observation of different celestial bodies through a telescope, Hubble found that the light from distant galaxies was shifted towards the red end of the spectrum. This red shift indicates that stars are moving away from us and from each other. This phenomenon is called the 'expansion of the universe', also known as the big band theory.

ANTONII [103]
The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span>  </span>

Answer No 1:

Process 1 is cellular respiration. Cellular respiration can be described as a process in which glucose and oxygen are converted into water and carbon dioxide. ATP is released by this process which is used as an energy source.

Process 2 is anaerobic respiration. It is a process which occurs in the absence  of oxygen. This process will also yield ATP.

Answer No 2:

The process 1, cellular respiration, is known to produce 38 molecules of ATP. Out of these, 2 molecules are the result from the process of glycolysis, 2 molecules arise from Kreb's cycle, rest 34 are known to occur from the electron transport chain.

The process of anaerobic respiration is known to make 2 molecules of ATP in total.

In what type of asexual reproduction are seeds produced even without the joining of sperm and eggs?
dem82 [27]
This type of asexual reproduction is called apomixis. 
Apoximis is reproduction by special generative tissues without fertilization. It includes parthenogenesis in animals, in which the new individuals develop from unfertilized egg, and apogamy in certain plants in which the generative tissues may be the sporophyte or the gametophyte.
