Robins typically lay four eggs. Four eggs allow the offspring to be well fed, whereas larger clutches may result in malnourished

chicks that have a lower chance of survival. Fewer than four eggs per clutch may result in no surviving offspring if the eggs are preyed upon. Which pattern of natural selection most likely acts to keep four eggs the most common clutch size

Answer:

Stabilizing selection

Explanation:

The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.

During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.

In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages.  Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.

Thus, Stabilizing selection is correct.

What are two abiotic and two biotic conditions in a coral reef that provide the conditions necessary for it to have high biodive
Elena L [17]

Answer:

The two abiotic conditions in the coral reef that contribute to the high biodiversity are:

  1. Temperature
  2. Sunlight

Whilst the abiotic factors are

  1. Plant and
  2. Bacteria

Explanation:

The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.

The above factors contribute immensely to the stability and operability of the great reef.

The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.

It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.

The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.

It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.

Cheers!

Describe respiration in frog and tadpole​
adell [148]

Answer:

Frog - The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. ... A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.

Tadpole - Tadpoles open their mouths as they swim and take in water. As the mouth closes, muscles transfer the water to the gills. These consist of thin membranes called lamellae, which take oxygen from the water where it enters the blood stream through the process of diffusion.

Activity A (continued from previous page) 4. Observe: Wait until the numbers are not changing very much. What do you notice abou
kkurt [141]

Answer:

Yes, dynamic equilibrium is present in the cell.

Explanation:

In dynamic equilibrium​, the concentration of solute remain the same due to equal flowing of solutes inside and outside the cell so there is no change occurs inside the cell, the cell maintain same concentration of solutes both inside and outside the cell. Dynamic equilibrium​ is a type of equilibrium in which the reactants and products formed at the same rate and no change occurs inside the reaction. In the cell, homeostasis is responsible for maintaining equilibrium in the cell so no change occurs inside the cell.
