Biodiversity is rapidly declining across the globe.

Explanation:

The biodiversity across the globe has been under heavy blow, especially in the past few hundred years. The main reason for this are the humans. The humans with their activities have managed to destroy the habitats in lot of places, which in turn resulted in sharp decline in biodiversity. Also, some species have been systemically killed off, some because they have been considered as pests, some because they were used as a food source.

  • Naturally, the biodiversity tends to be at a sustainable level, while some species die out, other replace them.
  • In the more recent history though, there is a mass extinction occurring because of the humans activities, not because of natural causes.
  • With the growing human population the trend of destroying the environment continues and it will continue further in the future, with the biodiversity constantly going down and lot of species ending up being endangered or extinct.

(03.05 hc) the base pairs in a dna strand are held together with hydrogen bonds. if the two nitrogenous bases in each pair were
asambeis [7]

The cell would have to take in and use more energy in order to break the covalent bonds.

The correct option is B

Hydrogen bonds :

are the chemical mechanism that governs the complementarity of the bases of DNA. This correspondence is unique thanks to the geometry of the hydrogen donor atoms and the acceptors that form the bases.

The (hydrophobic) bases are stacked inside the double helix of DNA; their plane is perpendicular to the axis of the double helix. The outside (phosphate and sugar) is hydrophilic.

The hydrogen bonds between the bases of one strand and the bases of the other strand keep the 2 strands united.

One purine on one strand necessarily binds to a pyrimidine on the other strand. As a corollary, the number of purine residues is equal to the number of pyrimidine residues.

* A binds to T (by 2 hydrogen bonds).

* G binds to C (via 3 hydrogen bonds: more stable bond: 5.5 kcal vs 3.5 kcal).

What part of the DNA strand do hydrogen bonds hold together?

hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

Which is a characteristic of fast-­twitch muscle fibers?
dimulka [17.4K]

Explanation:

Due to fewer capillaries, mitochondria, myoglobin, and lower oxygen transport, type II- fast twitch muscle fibers are "fast" or quick to fatigue. With their short-term contractions, they also create greater force and strength.
