Explanation:

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

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.

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.

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.

photosynthetic organisms

Explanation:

These are autotrophs organisms that use carbon dioxide and water, and with the help of solar energy, they produce nutritive material and release oxygen.

This is known as the process of photosynthesis and it is done in the organs of the plants that contain chloroplasts.

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.

Answer: The cell body

Explanation: I did the test its right!!!!

Answer:

Cell size at division is determined by the balance between cell growth (the increase in mass or volume) and the timing of cell division. Interestingly, faster growth rates in bacteria and eukaryotes lead to larger cell size. ... In this model cells “add” a constant volume (or mass) between cell divisions

Explanation:

Answer:

1. prokaryotic and Eukaryotic

2. cellular organism that lacks an envelope-enclosed nucleus.

3. organisms whose cells have a nucleus enclosed within a nuclear envelope.

4. both have a cell membrane

5. a plasma membrane: an outer covering that separates the cell's interior from its surrounding environment.

cytoplasm: a jelly-like cytosol within the cell in which other cellular components are found.

DNA: the genetic material of the cell.

ribosomes: where protein synthesis occurs

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.

Explanation:

Over time newer layers will be created from divergent boundaries and older layers recycled by convergent boundaries. The correct option is C.

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.
