Answer:
Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.

Are different dog breeds different species? Why or why not?
Answer:
They are the same species.
Explanation:
Full question: How come some similar animals are different species, while with domestic dogs, wildly dissimilar types are considered different breeds?
-- Z. Kornberg, Jerusalem
Michael Bruford, a professor of biological sciences at Cardiff University in Wales, explains the thought process behind this seeming double standard.
Scientists have been distinguishing between species on the basis of how they look, behave or live since recorded history began. However, two famous scientists stand out in terms of how we perceive species differences today: Carl Linnaeus, an 18th-century Swedish naturalist, and Charles Darwin. Linnaeus was the first person to formulate a single approach for describing species in a hierarchical manner according to their similarity, using his binomial nomenclature of genus followed by species (Homo sapiens, for instance). Darwin was among the first people, and certainly the most celebrated among them, to develop a credible theory on how species evolve (via natural selection). Both of these scientists' insights underpin most of what modern science utilizes when studying species and speciation.
Currently species are still primarily distinguished by their appearance, but it is becoming very clear that looks don't always tell us all we need to know about whether two organisms are different. Many so-called cryptic species exist that, to the untrained eye, look very similar or even identical to another organism--commonly found, for example, in nocturnal mammals such as bats and bush babies. If the two mated, however, they may never be able to produce viable offspring; this, in fact, is the primary criterion for dividing similar organisms into different species. Because of these red herrings--and also because the process of describing species is very long and labor-intensive--scientists are increasingly turning to DNA to assist them in identifying and describing species.
Which of the following is NOT a correct statement for plant tissue sampling procedures?
O Plant tissue samples should be free of soil particles
O The samples should be taken between mid-morning and mid-afternoon
O Taking any plant part for sampling is acceptable
O Rainy weather should be avoided when taking samples
Answer:
The answer is C: Taking any plant part for sampling is acceptable.
Explanation:
I have Agriculture and I took the test and I get the answer wrong the first time, but it told me the right answer after I got it wrong and it said that it was this.
During plant tissue sampling any plant part for sampling is not acceptable.
What is plant tissue sampling?Sampling of the plant tissue is an essential component of a crop fertility program. The analysis of the plant sample is generally done to see whether the crop is taking the nutrients appropriately or whether the plant is suffering from any kind of deficiency.
At the time of plant tissue sampling, one should not sample dust or soil contaminated tissue, that is, it should be free of soil particles. One should keep in mind that generally sampling is done between mid-morning and mid-afternoon.
The sample should be free from any kind of moisture, therefore, rainy weather should be avoided. During plant tissue sampling, any part of the plant is not sampled, generally the leaves or petioles of the plant is sampled for analysis.
Thus, the incorrect statement is the third one, that is, taking any plant part for sampling is acceptable.

please tell me why my dump truck is so fat anyways
A: Dump trucks are so big or fat because they are used to haul large loads of loose materials, such as dirt, rocks, sand, and coal, to construction sites, factories, or power plants. The open bed features a hinge at the rear of the truck so that hydraulic pistons located at the front of the bed can lift the front to dump the contents of the bed at the delivery site. The title of the world's largest dump truck went to the BelAZ 75710 which began moving rocks and coal in a mine in Siberia in 2014. The BelAZ 75710 is as long as two buses parked end to end, six times more powerful than modern Formula 1 racing cars, and heavier than a loaded Airbus A380 airplane. The entire vehicle costs over $6 million with each tire costing $42,000.
In short, they are big fat chonkers to carry big chonky stuff.

which of the following does not contribute to the formation of the mid atlantic ridge
Answer:
This submarine Mid-Atlantic Ridge owes its formation to the movement of the continental plates on either side of the ocean. As these plates slowly separate, they leave gaps in the earth's crust. This allows molten rock from beneath the earth's crust to reach the surface, forming a new part of the ocean floor

What is the main force that drives deep ocean currents?
Answer:
water density
Explanation:
These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

6. Bacteria, E. coli
7. Animals, plants
8. plasma membrane
9. Selective permeability of the cell membrane refers to its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others. Allowing some molecules through while blocking others.
10. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell.
Specialized proteins in the cell membrane regulate the concentration of specific molecules inside the cell.
Membrane carbohydrates perform two main functions: participate in cell recognition and adhesion, either cell-cell signaling or cell-pathogen interactions, and they have a structural role as a physical barrier.
Cholesterol plays has a role in membrane fluidity but it's most important function is in reducing the permeability of the cell membrane.

Which of the following would be true about the influence of plate tectonics on the
evidence of geologic time?
Over time new surface will be created from convergent boundaries and older
layers recycled by divergent boundaries
Over time older layers will be recycled from divergent boundaries and newer
layers created from transform boundaries
Over time newer layers will be created from divergent boundaries and older
layers recycled by convergent boundaries
Over time newer layers will be recycled by transfor boundaries and older
layers will be created from convergent boundaries
Answer:
3rd answer
Explanation:
Over time newer layers will be created from divergent boundaries and older layers recycled by convergent boundaries. The correct option is C.
What is plate tectonics?Tectonic plates, which are basically the large slabs of rock which usually divide the Earth's crust, are constantly moving and reshaping the Earth's landscape.
Plate tectonics theory proposes that the Earth's outer shell (lithosphere) is divided into several plates that glide over the rocky inner layer above the soft core.
Cooler parts of the Earth's crust were pulled downwards into the warmer upper mantle around 4 billion years ago, damaging and weakening the surrounding crust.
According to the authors, the process repeated itself until the weak areas formed plate boundaries.
Divergent boundaries will create newer layers over time, while convergent boundaries will recycle older layers.
Thus, the correct option is C.
