Number of neutron = mass number - atomic number
                               = 163 - 58

Number of neutrons of element X is 105.

In Alaska, grizzly bears must eat 10 fish and drink up to 25 liters of water to live. A
EleoNora [17]

The fish is the limiting factor because its population <u>determines the survival and availability  of the grizzly bears.</u>

A limiting factor is  resources(biotic or abiotic) that affects or determine the availabity and growth of an organism or group of an organism within an ecosystem.

The more fish it takes, the more the liver produces urea, and kidney tubules  makes use of the urea in it tubules for urine formation in the loop of Henle. The urine formation and loss, leads to intake of water and the sequence continues.

This is an example of a biological limiting factor because the bear  predate on the fish for survival and population.

If the population of the fish drops,( <u>the limiting facto</u>r) the bear drinks less water based on above, and therefore <u>disruptions  of the ecosystem</u>.

During drought years, seeds with thin coats are more likely to desiccate (dry out) and not be able to germinate
Morgarella [4.7K]

Directional selection favors one of the extreme phenotypes. Option B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.

<h3>What is directional selection?</h3>

Directional selection increases in the proportion of individuals with an extreme phenotypic trait.

There must be a selective pressure or environmental pressure acting on populations to lead the species to increase the number of individuals expressing that extreme phenotype.

This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.

In the exposed example the environmental pressure is drought during several years.

Drought periods decreases the fitness of plants that produce thin seed coats because they dehydrate before germinating.

Originally the population expressed both types of seeds. But after the drought pressure, only plants that produce seeds with thicker coats got to survive and reproduce.

The correct option is B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.
