One difference between algae and plants is that _____.

Biology
1 answer:
Zolol [24]3 years ago
5 0

Answer: plants have roots, stems, or leaves

Algae and plants are similar organisms because both are autotrophic organisms which are able to produce their own food by the process of photosynthesis. The main difference between the two is the level of complexity. Algae are comparatively simple organisms, their structure ranges from single celled to multi-cellular organisms. They do not exhibit true roots, stems and leaves like plants. The plants exhibit complex specialized structure for transport of water, nutrients and to perform reproduction. The smallest to largest plant will exhibit roots, stems and leaves.

What abiotic factors characterize salt marshes?
Vladimir [108]
<span>Salt marshes contain abiotic factors that release harsh salinity or too much amount of salt dissolved on their soil solution.
Here are some of the abiotic factors that characterize salt marshes
=> High amount of salinity
=> anaerobic soil
=> toxic from sulphide
=> high temperature
=> sudden changes to its photoperiod
=> scour and drag
=> The nutrient ions result to low proportion of the total amount present in the soil.
Thus, salinity and flooding are the major factors that affect salt marsh species

An unknown sample known to contain either triglycerides or phospholipids is placed in water. The sample forms a separate layer o
vodka [1.7K]

Answer: Option C) Triglycerides, long-chain hydrocarbon tails

Explanation:

Triglycerides are lipids, with three fatty acids (the same or different) having long hydrocarbon tails.

The hydrocarbon tails in triglycerides is the structural element that makes it insoluble in water as seen in the sample forming a separate layer on top of the water because it does not form hydrogen bonds with water molecules i.e hydrophobic

Thus, option C is the answer

Dan ""threw out his back"" after lifting heavy furniture and complained of pain radiating down the back of his right leg. Use an
Blababa [14]

When Dan "threw out his back", the anatomical terminology regions with the possibility of the injury occurrence is in alignment with the lumbar segment of the spine, having and impact on the sciatic nerve and leading to pain which is often known as the posterior region of the lower right limb. The imaging technique that would be employed in the diagnostics is Nuclear Magnetic Resonance Imaging.

Explanation:

One of the aftermath of physical activity - comprises of lifting weighty objects - is lower back injury, which often varies from painful muscle contraction, muscle tearing, or damage to the inter-vertebral disc of the lumbar spine.

In Dan's situation, the intent to lift the furniture could result to:

Protrusion of the disc that is found admist two vertebrae, known as herniated disc.

Lumbar disc hernias could results in compression of the sciatic nerve.

Sciatic nerve damages would lead to a variety of symptoms including pain or neurological disorders - which includes tingling, numbness, painful current, amidst others - in the region of that nerve.

Dan happened to feel pain at the back of his right lower limb, where the damage sciatic nerve flows through.

Which imaging technique would you prescribe to diagnose a spinal problem?

The best imaging technique to estimate the possibility of the occurrence of lesion with the diagnosis of a spinal injury is the Magnetic Resonance Imaging, which permits in studying the bone structure and the soft tissue (cartilage, muscle) of the influenced region.

The X-rays would only permit observation of the structures of the bones, that plays a important role in diagnosing fractures, deformities or structural variation, but would not reflect the actual form of the ligaments, inter-vertebral discs or muscle.

Which steps are part of the seafloor spreading process? Check all that apply. A crack forms in oceanic crust. Volcanoes erupt un
Alex73 [517]

The answer is;

A crack forms in oceanic crust.

Volcanoes erupt under the ocean.

Molten rock rises up through the crust.

New material pushes older rock away from the ridge.

Seafloor spreading occurs in divergent boundaries where two tectonic plates are moving away from each other. As the plates diverge, the void is filled up by upweling magma from the mantle. This causes an eruption at the boundaries causing a cascade of mountains along the ridge.  Therefore, the closer to the ridge you get, the newer the crust is.
