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.

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.

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.

Answer:

While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Brahe had collected a lifetime of astronomical observations, which, on his death, passed into Kepler’s hands. (Brahe, who had his own Earth-centered model of the Universe, withheld the bulk of his observations from Kepler at least in part because he did not want Kepler to use them to prove Copernican theory correct.) Using these observations, Kepler found that the orbits of the planets followed three laws.

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:

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.

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.

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.

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.

The statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.

Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. These daughter cells are genetically unique to the parental cells and are haploid in nature. Germ cells (gamete cells) are typically divided through this mode of cell division.

Oogenesis may be characterized as the process of female gamete formation including the formation of an oocyte from an oogonium followed by meiotic division. During the process of oogenesis, a haploid ootid cell and a polar body are formed with the help of meiotic division.

Therefore, the statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.
