Which statement best describes the effect of texture on absorption of radiant energy?
Rough and smooth surfaces do not absorb energy.
Rough and smooth surfaces affect the absorption equally.
Rough surfaces absorb more energy than smooth surfaces.
Rough surfaces absorb less energy than smooth surfaces.
Answers
Rough surfaces absorb more energy than smooth surfaces because of its irregular shape and low reflectance.
Describes the effect of texture on absorption of radiant energy?
Rough surfaces are better absorbers as well as emitters of heat energy than smooth surfaces because smooth surface is a good reflector and a poor absorber so its emissivity is low.
So we can conclude that Rough surfaces absorb more energy than smooth surfaces because of its irregular shape and low reflectance.

Answer:C on edge 2023
Explanation:
Cardiac muscle is striated.
Why is this beneficial?
A. because striated muscle has digestive enzymes, allowing it to
break through clogged arteries
B. because striated muscle tires easily
C. because striated muscle is voluntary, allowing you to stop your
heartbeat if necessary
D. because striated muscles can be trained, allowing you to
strengthen your heart with exercise
Answers
Answer:
D. because striated muscles can be trained, allowing you to strengthen your heart with exercise
Explanation:
Striated muscles convert chemical energy into physical work. You can make your striated muscles stronger with exercise. This helps the heart perform its function better and more efficiently.
Striated muscle does not have digestive enzymes and does not play a role in digestion. Striated muscles are very strong, and besides, that doesn't show why its beneficial anyway. It is impossible to voluntarily stop your heartbeat. If you did, you'd die.
Therefore, the best answer is D.

explain how the fossil record provides evidence for the idea of natural selection
Answers
Fossil records provide evidence of natural selection because one can see what species and what type of species (specifically what type of special trait the species had) reproduced and lived for longer.
For example, we have 5 different fossils of the same animal;
1. Lived about 45 years; had long legs that made it run faster - 5 offspring
2. Lived about 8 years; had short and stubby legs, was very slow - 0 offspring
3. Lived about 67 years; had long legs that made it run faster and a good nose - 8 offspring
4. Lived about 40 years; had a good nose and normal legs - 6 offspring
From all of that information you can see that the prefered trait was having longer legs and a good nose survived and reproduced multiple time, you can also see that the organism that had short legs did not survive for long and did not reproduce.

Explanation:
ANSWER:
75% of the offspring will have freckles according to the unit square prediction.
This is due to the dominance of dominant gene present in one of those parents. This is shown in their off springs, general the ratio of dominant to recessive is 3:1.

Where do the storms hit the hardest in europe?
Answers
Answer:
The effects of tropical cyclones in Europe and their extratropical remnants include strong winds, heavy rainfall, and in rare instances, tornadoes or snowfall. There are only two modern cyclones officially regarded as directly impacting mainland Europe while still fully tropical or subtropical: Hurricane Vince in 2005, which struck southwestern Spain as a tropical depression; and Subtropical Storm Alpha in 2020, which made landfall in northern Portugal at peak intensity. Hurricane Debbie in 1961 may have still been tropical when it made landfall in northwestern Ireland, but this is disputed.[nb 1] In 1842, it is believed that a hurricane struck Europe.

What is climate change?A climate change is a variation in the weather and the climate pattern due to a change in temperature and other atmospheric factors. It will lead to a transformation in the flow of carbon in the environment.
Increased carbon in surroundings increases temperature and results in a change in seasons and humidity levels, leading to changes in the rainfall.

How does the exchange of oxygen and carbon dioxide occur in the lungs and tissues ?
Answers
Answer:
Gas exchange happens in the alveoli in the lungs and the capillaries that envelop them. When you inhale oxygen, this one moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. In simple words the exchange comes from the inhalation and exhalation of gases

Vicki Arroyo: Let’s prepare for our new climate
Briefly summarize what Arroyo explains her talk will be about.
What are the three examples Arroyo gives for how we can prepare for the massive impact climate change will have on all of us?
According to Arroyo, how can we better prepare and adapt to violent storms and floods?
According to Arroyo, the second thing we need to prepare for is heat and droughts. What are some ways in which people are better preparing to handle these effects of climate change?
Although Arroyo does not mention the term “watershed,” it was discussed in the unit as being closely related to and impacted by drought and floods. Please discuss how the watershed relates to drought and heat. How might Arroyo have integrated the term watershed into her talk?
The third example that Arroyo talks about is rising sea levels. What are some of the ways rising sea levels can be highly dangerous and damaging? What are some of the solutions being implemented to prepare for the future?
At the end of her talk Arroyo says, “Adaptation’s too important to be left to the experts.” Explain what she means by this, if you feel this is a valid point and why.
Answers
A watershed is an area which drains to a common body of water, one of its main functions is to temporarily store and transport water from the land surface to the water body and ultimately (for most watersheds) onward to the ocean. So she can include watershed as drought preventive method in her talk.
What is climate change?Climate change is defined as a change in global or regional climate patterns, in certain a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
Rising sea level can be reduce by following solutions:
Beaches and dunes can act as a natural wall and reduce the impact of storm surge. The bigger the beach or larger the dune, the more water can be stopped from reaching homes and roads.
Coastal communities can restore natural infrastructure, that can act as a buffer against storms and coastal flooding. Natural structures such as barrier islands, and coral reefs, mangroves, and salt marshes can work alone.
