Answer:

These include shifts in the values and frequencies of particular traits among members of populations, often due to ecological processes such as the movement of organisms and changing environmental conditions as well as interactions with members of different species (e.g. predator-prey interactions, host-parasite .

A population's emigration in one month totaled three individuals. During the same period, immigration was 17 individuals. Natali
Ratling [72]

There was no net change in the given population. The size of the given population remains unchanged.

The explanation behind this is that if we consider the given values-

Emigration- 3

Immigration- 17

Natality- 12

Mortality-26

Therefore,

The overall effect on the population will be=

(Emigration+ Mortality) - (Immigration + Natality)

= (3+26) - (17 + 12)

=29-29

=0

Here the emigration means the number of people who have migrated from the population. Mortality refers to the number of deaths in a given population. Immigration is the migration of people into the population and natality is the overall number of births that have taken place in a population. Therefore there is no net gain or loss in the given population. This exerts no effect on the population keeping it unchanged.

At the source, sugars are: At the source, sugars are__________.
Alex_Xolod [135]

Answer:

d. Actively transported into the phloem

Explanation: Source is the place where sugar are been produced and are active transported to actively growing part of plants that requires it. The actively growing plants part that requires sugar are called sink.

Photosynthate the end products of photosynthesis is what is been loaded into the phloem through active transport and then moved to sink i.e plant part that requires the sugar through a process called translocation. The sink in plant includes the fruits, leaves for some vegetables,flowers for ornamental crop,too or tuber, rhizomes.

When the phloem cell is damage there is reduction in transport of photosynthate or accumulation in a particular part of plant.

Actively growing parts of plant have a high demand for sugar or sucrose than the old and weak parts of plants.

Which structure is less likely to suffer severe damage during an earthquake: a high-rise, steel- frame hotel built on sediment,
mars1129 [50]

Answer:

The correct answer is - A wood-frame house built on bedrock.

Explanation:

An earthquake would damage a steel-frame building built on sediment in comparison of a wooden house built on the bedrock due to the fact that waves of an earthquake do not go through solid things easily such as the earth core or the bedrock land rather than reclaimed land or sediments.

So, the bedrock will shake less than the hotel or heave building built on sediment. A house that made up of wooden-frame would shake only whereas the steel-frame might damage more.
