A population of drosophila flies lives in a forest and has variation in their egg-laying behavior. The majority of the flies have the trait of laying eggs in the rotting bark of trees. A small percentage of the flies have the trait of laying eggs in bark that is dampened by sap. The drosophila population moves into a new forested area that is drier, where rotting bark is harder to find than sap. How will the population change over several generations

Answers

Answer 1

Answer:

It will contain a larger proportion of flies that lay eggs in sap because the trait results in a higher chance of reproducing successfully and passing on the gene

Explanation:

Over the years the population of flies that lays egg in the rotten bark will reduce this is because of the low chance of reproducing and there will be an increase in the population of flies that lays egg in the sap because the flies have a higher chance of reproducing successfully leading to an increase in the population and the ability of the gene to be passed on successfully to their offspring in next generation.

a mass extinctions is

Answers

Answer:

Mass extinction is when biodiversity or species in a living habitat decreases to about three-fourths of its original number or to none. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Mass extinctions are usually associated with organisms that are macroscopic rather than microscopic. Examples of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.

In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar.

Answers

Answer:

Actively forms a peptide bond by acting as a ribozyme aid in initiation of protein synthesis.

Explanation:

The role of the 23S rRNA of the large ribosomal subunit of E. coli during protein synthesis is the formation of a peptide bond by acting as a ribozyme aid in initiation of protein synthesis. 23S rRNA has an important function of peptidyl transferase. Both peptidyl-tRNA and aminoacyl-tRNA are necessary for synthesis of protein and transpeptidation response. The 23S rRNA positions have a significant function in the binding of tRNA in P site of the large ribosomal subunit.

b. broad leaves to catch available light
c. vines and structures to climb towards sunlight
d. thick, waxy leaves

Answers

Answer:

large eyes to see in the darkness

b. broad leaves to catch available light

c. vines and structures to climb towards sunlight

Explanation:

This because Adaptation refers to the ability of plants or animals to adapt, survive and reproduce in it's environment through its developed structural which help it to do so. Plants in the rainforest enjoy abundance of rain and there are thick forest of trees and shrubs. Therefore animals there normally have broad eyes to see in the darkness because the trees form shade easily. The plants normally have broad leaves to receive sunlight

Answer:

- broad leaves to catch available light

- vines and structures to climb towards sunlight

- large eyes to see in the darkness

Explanation:

Organisms that live in rainforests have adaptations that enable them to live in the different conditions that exist in each layer.

E) the economic activity of the town of Newtok is extremely polluting and thus a big contributor to the environmental changes that have turned its residents into the first climate change refugees in the United States.

Answers

Answer:

The correct answer is D)

Decades ago, the U.S. government mandated that they and other Alaskan natives abandon a nomadic life based on hunting and fishing for sedentism.

Explanation:

Sedentism is simply the practice of settling in one geographical location for a long time.

Many governments encourage this to ensure that agricultural systems become developed and more sustainable as was the case in Alaska.

Other governments in some part of the world are also in support albeit for a different reason such as security of lives and property.

gravity? O
(1 Point)
B) Precipitation of water that has condensed from clouds
D)Water seeping into the ground to enter an aquifer
C)Water flowing in a river toward the ocean
A) Evaporation of water from the ocean to form clouds

Answers

The correct answer is A. Evaporation of ocean water to form clouds.

Explanation

The water cycle is a series of physical-chemical phenomena in which water goes through three states (liquid, solid and gaseous). In this process, the water in a liquid state is evaporated becoming in a gaseous state, and rising towards the sky (against the force of gravity) forming clouds. Once in the clouds, the water condenses, going from a gaseous to a liquid state. After this process, the water precipitates by the action of gravity towards the earth where a process such as the filtration of water in the soil occurs, forming aquifers, the accumulation of water in the rivers that flow into the sea, the freezing of water on the snowy peaks of the mountains, among others. According to the previous explanation, the correct answer is A. Evaporation of ocean water to form clouds.

What is dissolved oxygen in water?

Dissolved oxygen (DO) is the quantity of oxygen that is current in water.

Water bodies obtain oxygen from the atmosphere and from aquatic plants.

Rushing water, such as that of a fast moving stream, dissolves more oxygen than the still water of a pond or lake

What happens to a population when its size is equal to the carrying capacity?
a. Its size fluctuates wildly.
b. It increases in size.
c. Its size stays steady.
d. It decreases in size.

Answers

Answer:

C

Explanation:

When a population reachs its carrying capacity it will slow down and become steady due to the population reaching its limit on food, water, etc. and they can only feed so many.

When population size is equal to the carrying capacity then "Its size stays steady".

What is population ?

A population means the total number of individuals who cohabit in a certain area.

What is steady-state?

A biofilm that exhibits no net growth or degradation over time is usually referred to as a steady-state biofilm.

A population might slow down and stabilize once it reaches it's own carrying capacity since it will no longer be able to consume as much food, water, and other resources.
