What r some adaptions that help animals who live in the Alpine biome survive​

Biology
1 answer:
neonofarm [45]3 years ago
4 0

The animals that live in the Alpine biome have to have special adaptations to survive in it as this is a biome with very harsh conditions for big portion of the year. The temperatures are very low, the winds are strong, winter lasts for half a year or more, and there's lot of snow. All this has made the animals to develop certain traits to help them survive. Some of those adaptations are:

- thicker and longer fur for better isolation form the outside conditions

- wider paws with denser and tougher skin, helping them to move easier in the snow and avoid frostbite

- larger lungs and nostrils for easier breathing in the high altitudes

- stockier bodies so that heat can be preserved easier

- the ears and tails are small and rounded in order to avoid frost bite

- big portion of them are able to hibernate for several months

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve
kkurt [141]

Answer:

The correct matches are:

  1. In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
  2. In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
  3. In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
  4. In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

  • Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
  • Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
  • Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
  • Since, NADH is donating its H+, it is being oxidized to NAD+.

A certain first-order reaction a → b is 25% complete in 42 min at 25°c. What is the half-life of the reaction?
yan [13]

Answer:

t_{\frac{1}{2}} = 101.16 minutes

Explanation:

For a First order reaction, the rate constant is determined by

k = \frac{2.303}{t} log \frac{a}{a-x}

Where

k= rate constant

t= time required for a reaction

a= initial concentration

x= amount of reactant decomposed in time t

a-x= amount of reactant left after time t

Let the initial concentration be 100

Then

x = 25\\a-x = 75

Substituting the given values in above equation, we get -

k = \frac{2.303}{42} log \frac{100}{75} \\

k = 6.85 *10^{-3}

Also,

k = \frac{0.693}{t_{\frac{1}{2}} } \\t_{\frac{1}{2}} = \frac{0.693}{6.85 *10^{-3}}\\

t_{\frac{1}{2}} = 101.16 minutes
