Answer 2

Answer:

Identification of cockroaches is limited here to  adults. A major source of confusion is the recognition of adults from nymphs.There are  subjective differences, as well as morphological  differences. Immature cockroaches are known as  nymphs. Nymphs closely resemble adults except  nymphs are generally smaller and lack wings and  genital openings or copulatory appendages at the  tip of their abdomen. Many species, however, have  wingless adult females. Nymphs of these may be  recognized by their shorter, relatively broad cerci  and lack of external genitalia. Male cockroaches  possess styli in addition to paired cerci. Styli arise  from the subgenital plate and are generally conspicuous, but may also be reduced in some species.  Styli are absent in adult females and nymphs

Which best describes the way a sound wave is sent through the radio?

sound wave → radio wave
radio wave → sound wave
radio wave → sound wave → electrical signal → sound wave
sound wave → electrical signal → radio wave → sound wave

Answers

The answer is sound wave-electrical wave-radio wave

Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.

What is a sound wave?

A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.  

The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.

These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.

Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

Some seeds are endosed in a sweet, fleshy fruit. How would damage to the vascular tissue (Xylem and pholem, affect the developing fruit? A.Damaged vascular tissue would cause the developing fruit to accel in growth.
B . It would not affect the developing frut but it would affect the flower.
C. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all.
D.The xylem and pholem are not parts of a plant and therefore would not affect anything.​

Answers

Answer:

C. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all.

Explanation:

If the vascular tissues such as xylem and phloem are damaged, the fruit does not completely develop because the food that is produced in the leaves does not reach to the seed. The xylem helps in the transportation of water from the soil that is necessary for making of food during the process of photosynthesis so damaged xylem will not produced food and no food will be transported from leaves to seeds and if some food is produced by the leaves the phloem does not transport it to the seeds.

Explanation:

North Carolina’s biotech industry is quickly expanding.

Within the state, there are more than 600 life science companies employing 61,000 people at an average salary exceeding $81,000 a year – which is nearly twice the state’s overall private sector wage, according to the North Carolina Biotechnology Center.

In total, life science companies and institutions in North Carolina generate $73 billion in economic activity, which is an increase of 23 percent in two years, and account for 228,259 direct and indirect jobs, says North Carolina Biotechnology Center.

Furthermore, while employment in the nation’s life science industry rose by 7.4 percent from 2001 to 2012, North Carolina’s grew at a surprising 31 percent, even with setbacks from the Great Recession of 2008.

Following closely behind California, North Carolina outpaced life science industry growth in other states, including Texas, New York, Massachusetts and Florida, between 2009-2012, according to the U.S. Bureau of Labor Statistics. In the chart below, North Carolina's life science industry grew 5.2% from 2009 to 2012. While California's life sciences industry increased even more at 5.5% during the same time period, other states such as Pennsylvania and New Jersey actually saw their life sciences sectors shrink by 7% and 7.3%, respectively.

A light bulb has a resistance of 4 ohms and a current of 2 A. What is the voltage across the bulb?
volts

Answers

Answer:

8 V

Explanation:

V= IR

V = 4×2

V= 8 V

The answer is the ohms × current

Voltage is an electrical difference of potential across the circuit. The voltage of the bulb is 8V with a current of 2 A and a resistance of 4 ohms.

What is ohms law?

Ohms law gives the relation between the current (I) in Amperes, voltage (V) in volts, and resistance (R) in ohms. The formula to calculate voltage is given as,

[tex]\rm V = I \times R[/tex]

Given,

Current (I) = 2 Ampere

Resistance (R) = 4 ohms

Substituting values in the equation to calculate voltage as:

[tex]\begin{aligned} \rm V &= \rm I \times R\\\\&= 2 \times 4 \\\\&= 8\end{aligned}[/tex]

Therefore, 8 V is the voltage developed across the bulb with 4-ohm resistance.

Just as slow-moving water loses sediment, fast-moving water can pick up new sediment to carry. Which part of the river
bend will experience the greatest amount of new erosion? How will this erosion affect the shape of the river?

Answers

Answer:

The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.

The water flowing at the maximum velocity and with the greatest ability to erode is on the outside of the curve, rivers that meander erode in both directions.

What factors affect the river?

Cut bank erosion occurs when the edge of a stream channel bends, and it increases the loop of the meander, water that moves more quickly has greater kinetic energy.

It can therefore transport bigger particles, more articles may also be carried by it, and bigger and larger particles can be carried by a stream as it moves more quickly. The capacity of a stream increases with the size of the particles it can transport.

Therefore, a stream will have a quicker velocity if it has a steep slope or gradient, which implies it may transport heavier items in suspension.

What is the relationship between capillaries and lymph vessels

Answers

Answer Blood vessels deliver oxygen and nutrients to virtually all cells in developing mammalian embryos and adults, whereas lymphatic vessels drain the interstitial fluid that collects in tissues, and serve as a conduit for immune cell trafficking and fat absorption.

: Lymphatic capillaries collect lymph fluid from the tissues, which allows them to regulate the pressure of interstitial fluid. This fluid is essentially plasma that leaks out of cardiovascular capillaries into the tissues due to the forces of hydrostatic or oncotic pressure.

What has happened to Earth due to the pollution?

Answers

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
