What is a possible reason for extinction?

Biology
1 answer:
Taya2010 [7]2 years ago
7 0

Answer:

The number of habitats falls below a critical level.

Explanation:

The possible reason for extinction is that the number of habitats falls below a critical level. This makes it impossible for organisms to survive.

  • A habitat is the dwelling place of living organism in an ecosystem.
  • The resources and other materials that ensures the survival of an organism are made available in the habitat.
  • When a habitat begins to thin out and can no longer support organisms, then extinction will ensue.

Which is not characteristics of all mammals?
alexgriva [62]

Answer:

b. giving birth to live young (viviparous)

Explanation:

Monotremes include duck-billed platypus and few other mammalian species that are oviparous. These mammalian species do not give birth to young ones, that is, they are not viviparous. Rather they lay eggs and are oviparous.

These species are also characterized by the absence of teeth. The primitive monotremes also exhibit external fertilization.

Examples of egg-laying mammals include anteaters or echidnas and the duck-billed platypus. The laid eggs are carried by females in an abdominal ouch to keep them warm.

gregori [183]

Answer:

In case, when an allosteric site undergoes certain modifications it will demonstrate some changes like change in affinity towards the inhibitor, however, how the changes take place is not known exactly because of less knowledge of the FX11 composition. Though it is for sure that the modification will decline the affinity and the FX11 will exhibit less efficacy in preventing the growth of C. parvum.  

An inhibitor targets the allosteric site as the size and the functional groups present within the site matches with that of the inhibitor, and thus affinity is attained. However, when there is a change in structure, the affinity will also get influenced.  

The gossypol and FX11 can be utilized as drugs for human beings as these substances prevent the process of lactic fermentation, and the pathway for lactic fermentation generally is less common in human cells. The parasite C. parvum is found within the digestive tract, and the process of anaerobic respiration usually does not take place in the organs present in the digestive tract. However, in specific cases, only the muscle tissue can go through anaerobic respiration like in the case of performing physical activity. It is also to be noted that the drug can even invade other tissues via blood, therefore, at the time of consuming drugs, there is a need to instruct the patients to prevent any kind of physical activity.

Explain how the boiling of water and the cooling of water vapor is a reversible reaction.​ With hydrogen bonds between water mol
My name is Ann [436]

Answer:

When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.

So it is reversible reaction.

Explanation:

Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.

In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.

When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.

So it is reversible reaction.
