Which agent of erosion most likely moves sediments in a sand dune? *
1)Wind
2)Running water
3)Glaciers
4)Wave action
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.

A regular progression of species replacement is called __________.
Answer:
this should help you figure this out!
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.
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.

There are 40 individuals in population 1, all with genotype A1A1, and there are 25 individuals in population 2, all with genotype A2A2. Assume that these populations are located far from each other and that their environmental conditions are very similar. Based on the information given here, the observed genetic variation is most likely an example of:
a. genetic drift.
b. gene flow.
c. disruptive selection.
d. discrete variation.
e. directional selection.
Answer:
Genetic drift
Explanation:
Genetic drift can also be referred to as allelic drift, it refers to the variation in allelic frequencies within a particular population over a period of time. It can also be referred to as the random fluctuations in the number of genotypes within a population. Genetic drift is not influenced by the environment and is usually more pronounced in a small population of organisms.
For example, a population of birds can consist of green feathers and blue feathers with the green feathers as the dominant allele, but as a result of random fluctuations, the offspring may all be with green feathers and hence could eliminate or reduce the allele responsible for blue feathers over time.
What happens to the nitrogen when organisms die?
Final answer:
When organisms die, the nitrogen in their bodies is released through decomposition and can be recycled back into the environment through various processes.
Explanation:
When organisms die, the nitrogen in their bodies is released through the process of decomposition. Decomposers, such as bacteria and fungi, break down the organic compounds in dead organisms and release nitrogen in the form of ammonium ions into the soil. This ammonium can then be absorbed by plant roots or converted into nitrates by nitrifying bacteria in the soil. Ultimately, this nitrogen can be recycled back into the atmosphere through the process of denitrification, where bacteria convert nitrates back into nitrogen gas.
Why is only a small amount (approximately 10%) of energy available from
one trophic level to the next in a food web? *
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.

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
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.
The beaches at a nearby lake have been closed because of high E. coli counts. The lake is surrounded by agricultural areas and summer cottages. We know that different species of vertebrates have different E. coli strains in their digestive tracts. What represents a hypothesis for the source of the high E. coli counts?
Answer:
Runoff from dairy farms causes high E. coli counts
Explanation:
Based on the scenario being described within the question it can be said that one hypothesis for this would be that the runoff from dairy farms causes high E. coli counts. This is because this runoff caries vasts amounts of organisms across the land and brings various animals which drink from the excess water and spread and increase the e.coli count.

In the moss life cycle, diploid cells within a sporangium undergo meiosis to produce haploid spores. Therefore, option c is correct
- Sporangium: The sporangium is a structure in mosses that contains diploid cells.
- Meiosis: Within the sporangium, diploid cells undergo meiosis, a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid spores.
- Haploid Spores: These haploid spores are released from the sporangium and dispersed by wind or water, eventually germinating into haploid gametophytes, the next stage in the moss life cycle.
- Alternation of Generations: Mosses exhibit alternation of generations, where the haploid gametophyte generation alternates with the diploid sporophyte generation.
- Importance: This process ensures genetic diversity in moss populations by shuffling genetic material through meiosis, ultimately contributing to the survival and adaptation of mosses in diverse environments.

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