In horses, the allele for long legs (L) is dominant over the allele for short legs (1). What is the
probability of short legs in the offspring of parents that are both heterozygous for the trait?
Answer:
[tex]\frac{1}{4}[/tex] or 25%
Explanation:
Heterozygous means that the organism has different alleles (L1)
Draw a punnet square:
L 1
L LL L1
1 L1 11
11 is the allele for short legs so 1 in 4 of the outcomes will lead to an offspring with short legs

(1 Point)
1.To detect changes and feel sensations
2. To initiate appropriate responses to changes
3. To organize information for immediate use and store it for future use
4. Absorb extra fluid between the cells
Answer:
4. Absorb extra fluid between the cells
Explanation:
The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.

1. Explain why the greenhouse effect is necessary but how an enhanced greenhouse effect can harm the planet.
2. Define global warming and explain what has caused the recent trend of warming that the earth is experiencing.
3. Explain why Earth's temperature is directly affected by the amount of greenhouse gases in the atmosphere.
4. Define carbon sequestration and explain how deep geologic burial of carbon works.
5 Describe the connection between fossil fuel burning, the melting of polar ice, and the rising of global sea levels.
Answer:
1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.
2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.
3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.
4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.
5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.
Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. 3. Human activities contribute to global warming by increasing the greenhouse effect. ... Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. 4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. 5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. This expansion in turn causes sea levels to rise. ... There is now so much warming baked in to the global climate system that sea levels will continue to rise for centuries.
Explanation:
where is wind energy taken from
Answer:
The sun's uneven heating of the atmosphere, changes in the earth's temperature, and the earth's rotation all contribute to wind. Wind flow patterns are influenced by mountains, bodies of water, and plants. Wind turbines work by spinning propeller-like blades around a rotor to turn wind energy into electricity.

In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles
Answer:
The correct answer is - increase: constriction of the arterioles.
Explanation:
When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.
It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

7. Based on what you know about Carbon Dioxide (look at the definitions section) and the Description of the Landscapes, how did the amount of Carbon Dioxide in the atmosphere increase over time? 8. Carbon Dioxide and Water vapor are greenhouse gases. How do greenhouse gases act like the glass in greenhouses?
Answer: Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. Global atmospheric carbon dioxide concentrations (CO2) in parts per million (ppm) for the past 800,000 years. ... Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. The large numbers of land animals raised to feed the Earth's growing population results in increased carbon dioxide levels in the atmosphere due to farming practices and respiration and methane production. This is another example of how human activity indirectly affects biogeochemical cycles in a significant way. 8. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse.
