How does the attachment of spindle fibers differ between mitosis and meiosis I?

Answer:

OCEAN LITTER

Litter in the world’s oceans comes from many sources, including containers that fall off ships during storms, trash that washes off city streets into rivers that lead into the sea, and waste from landfills that blows into streams or directly into the ocean. Once in the ocean, this debris may degrade slowly and persist for years, traveling the currents, accumulating in large patches and washing up on beaches.

PESTICIDES AND FERTILIZERS

Use of pesticides and fertilizers on farms has increased by 26-fold over the past 50 years, fueling increases in crop production globally. But there have been serious environmental consequences. Indiscriminate pesticide and fertilizer application may pollute nearby land and water, and chemicals may wash into nearby streams, waterways and groundwater when it rains. Pesticides can kill non-target organisms, including beneficial insects, soil bacteria and fish. Fertilizers are not directly toxic, but their presence can alter the nutrient system in freshwater and marine areas. This alteration can result in an explosive growth of algae due to excess nutrients. As a result, the water is depleted of dissolved oxygen, and fish and other aquatic life may be killed

AIR POLLUTION

Air pollution brings to mind visions of smokestacks billowing black clouds into the sky, but this pollution comes in many forms. The burning of fossil fuels, in both energy plants and vehicles, releases massive amounts of carbon dioxide into the atmosphere, causing climate change. Industrial processes also emit particulate matter, such as sulfur dioxide, carbon monoxide and other noxious gases. Indoor areas can become polluted by emissions from smoking and cooking. Some of these chemicals, when released into the air, contribute to smog and acid rain. Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease. Long-term exposures also can lead to significant climatic changes that can have far reaching negative impacts on food, water and ecosystems.

NOISE AND LIGHT POLLUTION

Artificial light and noise often drown out natural landscapes. In the Arctic, the sounds of oil and gas explorations are so loud that belugas, bowhead whales and other sea life have had difficulty feeding and breeding. Light pollution disrupts circadian rhythms for both humans and animals alike and may even contribute to the development of cancer. Light pollution also can impact sea turtles. Adult and hatchling sea turtles are drawn toward lights along the beach, thinking they are heading toward the moon. Coastal developments, therefore, are encouraged to turn off their lights or cover them at night

Explanation:

Answer:

Tropism can be called positive or negative. Positive tropism is movement or growth towards a stimulus, whereas negative tropism is the movement or growth away from a stimulus.

Explanation:

Positive Tropism is growing towards a stimulus.

Negative Tropism is growing away from a stimulus.

Salmonella is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,600 serotypes.

Explanation:

Answer: Ok Salmonella is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,600 serotypes.Salmonellosis is an infection with a bacteria called Salmonella, Salmonella live in the intestinal tracts of animals, including birds. Salmonella are usually transmitted to humans by eating foods contaminated with animal feces. Every year, approximately 40,000 cases of salmonellosis are reported in the United States.

Organism classification: Salmonella enterica

Lower classifications: Salmonella bongori

Answer:

The thymus plays an important role in deletion of potentially autoreactive T cells. However, the presence of islet-specific T cells in the circulation of type 1 diabetes patients and healthy subjects indicates that the thymus is not capable of efficiently deleting all autoreactive T cells (Mathis and Benoist 2009).

Answer:

A: beta cells of the pancreas

Explanation:

Type 1 diabetes makes the pancreas produce little to no insulin.

Explanation:

this is the complementary strand in mRNA.

A=U

G=C

C=G

T=A

this is the answer key to any mRNA strand.

Hope this helps! :)

The DNA has adenine (A), cytosine (C), guanine (G), and thymine (T) bases whereas RNA is composed of adenine (A), cytosine (C), guanine (G), and Uracil(U).

It is the process by which RNA is formed from a DNA molecule.

A pairs with U, C pairs with G, G pairs with C, and T pairs with A. The first base of each pair belongs to the template strand of the DNA while the other is RNA.

DNA: G A T C G A T A C C A T T C G G C G C A T A C T T C G
