Populations and Communities Unit Test 3 of 34Items Item 3 Two closely related species of birds live in the same tree. Species A feeds on ants and termites, while Species B feeds on caterpillars. The two species coexist successfully because they interbreed The two species coexist successfully because each occupies a different niche The two species do not coexist successfully because they compete for food The two species do not coexist successfully because they use different methods of reproduction

Answers

Answer: The two species coexist successfully because each occupies a different niche.

Explanation:

Two species of birds that are closely related to each other tend to live on the same tree because they occupy different niche. Two different species coexist as they have different food preferences.

Niche of the species can be defined as the the contribution of the species in the ecosystem and different organism contributes differently in the ecosystem.

There are many factors such as distribution, temporal and spatial distribution which can be different for both of the species.

So, the difference in the niche of the species enables them to coexists.

Explain how one receptor can induce different phenotypes in different cell types.

Answers

Answer:

It is possible since a receptor can activate different signaling pathways in different cell types  

Explanation:

In a cell, a receptor bind to a specific ligand to activate a signaling pathway, while the same receptor may bind either with the same or another ligand in another cell type and thus activate another signaling pathway

One receptor can induce different phenotypes in different cell types as a

result of the ability to activate different signaling pathways in different cell

types  in the body.

Receptors are compounds which have a particular substrate it binds to which are known as ligands when information is to be conducted from one point to another.

Cells have receptor which bind to a specific ligand in order to activate a

signaling pathway. The receptor however can bind to a ligand found in

another type of cell which explains how it's able to induce different

phenotypes in different cells.

C)Sand
D)Cobbles

Answers

The largest sediment that can be transported by a stream that has a velocity of 50cm/sec is; Sand.

Stream Velocity

First, a general relationship between stream Velocity and diameter of the sediments is that as the stream Velocity increases, the diameter of the sediments increases and vice versa.

Additionally, the slower the stream Velocity, the lighter is the sediment it can transport.

Hence, the stream in discuss can transport sand sediments.

https://brainly.com/question/2621857

Final answer:

A stream with a velocity of 50 cm/sec can transport larger sediments. Among the options provided, cobbles are the largest sediments that can be transported by a stream with this velocity.

Explanation:

The size of the sediment that a stream can transport depends on its velocity. In the case of a stream with a velocity of 50 cm/sec, it is capable of moving larger sediments compared to a slower-moving stream. From the options provided, the largest sediment that can be transported by a stream of this velocity is D) Cobbles.

Explanation:

a somewhat regular progression of species replacement is called succession consists of a community and all the physical aspects of its habitat such as the soil water and weather. Ecosystem.

Final answer:

Ecological succession is the term used to describe a regular progression of species replacement in an ecosystem, whereby increasingly complex species adapt and replace the existing species until a stable climax community is established.

Explanation:

A regular progression of species replacement is called ecological succession. This is a process observed in ecology where ecosystems change and develop over time. At the start of this process, a relatively barren area may only support simple life forms such as algae or bacteria. As time progresses, increasingly complex species adapt to the new conditions and replace the existing species. This continues until a stable community is established, often referred to as a climax community. An example of this could be a new volcanic island that initially has no life, but over hundreds of years, becomes a complex forest ecosystem.

Which of the following characteristics is (are) possessed in common by true mosses, ferns, and spike mosses, and therefore becomes useless at helping to determine to which of these groups flower of stone belongs? 1. a sporophyte generation that is dominant 2. true leaves and roots 3. flagellated sperm 4. alternation of generations

Answers

Final answer:

True mosses, ferns, and spike mosses possess alternation of generations in common, which becomes useless for determining the flower of stone's group. Other characteristics they share include the presence of a sporophyte generation that is dominant.

Explanation:

Mosses, ferns, and spike mosses share the presence of alternation of generations, which is the cycle of having a haploid gametophyte stage and a diploid sporophyte stage in their life cycles. The sporophyte generation is dominant in these plants, meaning it is the more visible and longer-lived stage.

In terms of the other characteristics listed, true mosses, ferns, and spike mosses differ. True mosses have simple midrib-like structures resembling true leaves, while ferns have fronds and spike mosses have strap-like leaves. True mosses and spike mosses have flagellated sperm, while ferns do not. Additionally, true mosses and spike mosses lack true roots, instead having multicellular rhizoids, while ferns have true roots and leaves.

Limestone is the type of rock would most likely be weathered by acidic groundwater to produce a cave. So, the correct option is (D).

What is Limestone?

Limestone is a type of carbonate sedimentary rock. It is the main source of physical lime made from the mineral calcite and aragonite, which are different crystal forms of CaCO₃. Limestone is formed when these minerals precipitate out of calcium-rich water.

Limestone is formed when slightly acidic groundwater seeps through limestone rocks that dissolve a hole in the rock. The hole grows in size over time to form caves which are sometimes miles long.

Groundwater carries the dissolved calcite in solution and deposits it in other caves as limestone.

Thus, limestone is the type of rock would most likely be weathered by acidic groundwater to produce a cave. So, the correct option is (D).

Why is only a small amount (approximately 10%) of energy available from
one trophic level to the next in a food web? *

Answers

Answer:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat

Explanation:

Final answer:

Only about 10 percent of the energy at one trophic level is available to the next level, with the rest being used for metabolic processes or lost as heat. This energy loss is why food chains usually have no more than four trophic levels.

Explanation:

Energy is passed up a food chain or web from lower to higher trophic levels. However, generally only about 10 percent of the energy at one level is available to the next level. The other 90 percent of energy is used for metabolic processes or given off to the environment as heat. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web.

Explanation:

An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.

Recall that DNA is a long strand with a many repeating base pairs. In order for DNA to reproduce, the base pairs must be split apart. One half of the strand is then used as a template to build a new strand of DNA.

The enzyme helicase is responsible for splitting DNA along the base pairs. Helicase moves along the DNA strand unzipping the strand just as a zipper.

Answers

Explanation:

which agent of erosion most likely moves sediments in a send dune.

Glaciers

The agent of erosion most likely moves sediments in a send dune is wind. Thus, option A is correct.

What is wind?

Wind has been defined as the geological phase through which a landform or land mass has been attached to sediments, soil, and rocks.This occurs when the wind slows down or some barrier, like a rock or a clump of grass, traps the sediment of wind-blown sands.

Wind deposition is an agent of erosion which most likely moves sediments in a sand dune. This increases in pace as the wind passes up and over the barrier. It takes the grains of sand up the gently sloping, salting upwind side of the dune.

Natural sand dunes usually start as windblown sand that accumulates in a sheltered area behind some type of obstacle such as piles of seaweed and a hill of sand made up of wind on the coast or in a desert and it is because of erosion by wind strong winds blow across the loose sand on the surface of the earth including sands found in deserts.

Therefore, The agent of erosion most likely moves sediments in a send dune is wind. Thus, option A is correct.

The hill is covered in gravel so that the truck's wheels will slide up the hill instead of rolling up the hill. The coefficient of kinetic friction between the tires and the gravel is k. This design has a spring at the top of the ramp that will help to stop the trucks. This spring is located at height h. The spring will compress until the truck stops, and then a latch will keep the spring from decompressing (stretching back out). The spring can compress a maximum distance x because of the latching mechanism. Your job is to determine how strong the spring must be. In other words, you need to find the spring constant so that a truck of mass mt, moving at an initial speed of v0, will be stopped. For this problem, it is easiest to define the system such that it contains everything: Earth, hill, truck, gravel, spring, etc. In all of the following questions, the initial configuration is the truck moving with a speed of v0 on the level ground, and the final configuration is the truck stopped on the hill with the spring compressed by an amount x.
