Answer:

The threats of California soil resources are soils, urban development

Explanation:

Native soils, unmodified by human activity, are becoming rare and we are losing the valuable power they provide. Soils in the Delta continue to subside.

Urban development has expanded into vast acres of prime farmland in California, diminishing our capacity to produce sustainable food and fiber.Increased fire frequency will increase soil erosion, resulting in depletion of nutrients from the soil and polluting the surface waters that receive the runoff.

There are many threats to the soil resources in California some of them are Hydraulic mining, Forest fires, and Solar plant installation.

EXPLANATION:

Soil resources are said to be degraded when there is a decline in soil productivity.
This decline in soil productivity can be due to many factors.
The balance between the soil and the environment is usually disturbed by humans.
The first threat is the hydraulic mining in California disturbed natural soils.
Agriculture in California only depends on irrigation and the changes in water budgets largely affect the soil there.
Forest fires and its activities that are carried out to suppress fire causes soil erosion.
Also, the construction of solar and wind power facilities is disturbing the soil in deserts.
Thus, gradually California is reaching a point where undisturbed soil is rarely found.

Aleonysh [2.5K]

Answer:

c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.

Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.

Answer:

NeanderthalsThese artistic innovators were probably Neanderthals. Dated to 65,000 years ago, the cave paintings and shell beads are the first works of art dated to the time of Neanderthals, and they include the oldest cave art ever found

Explanation:

Which hominids created art? The first human artist on Earth is believed to have drew on a cave wall with red ochre over 65,000 years ago, as a Neanderthal reached out and drew on it. There is no evidence that the modern human is the only species to express itself through art, as is widely believed.

Leni [432]

Bright cherry red color is produced upon the addition of methyl red indicator to a culture of a Gram negative bacilli in MR-VP broth if the organism used the mixed acid pathway of fermentation.

What is MR-VP test?

As part of the IMViC testing, Methyl Red (MR) and Voges-Proskauer (VP) broth is utilized as the medium in which both the Methyl Red and Voges-Prosakuer tests can be conducted.
It is a straightforward broth made up of dextrose or glucose, buffers, and peptone.
In the Methyl Red test, an infected tube of MR-VP broth is mixed with the pH indicator methyl red.
The acids will overwhelm the buffers in the medium and create an acidic environment if the organism employs the mixed acid fermentation pathway and creates stable acidic end products.
If acidic end products are present when methyl red is introduced, the methyl red will remain red.
