Explanation:

Some structures are internal, like the lungs, brain, or heart. Other structures are external, like skin, eyes, and claws. Some structures are unique, like the long neck of a giraffe. Other structures are more common, like a heartStructure and Function: Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction.

All of these statements can be considered signs of global warming. They provide evidence of changes in the Earth's climate that are consistent with the predictions of climate models and the understanding of the underlying physical processes.

Answer: Variation, Difference between traits in individuals of the same species ... The population will not only evolve ( change in its genetic makeup and inherited traits), but will ... Evolution is not the same as adaptation or natural selection.

Answer:

It destroy both harmful and beneficial microbes.

Explanation:

If scientist added a chemical to destroy the arctic microbes, the beneficial as well as harmful microbes also eliminated from that area where chemical is applied. The removal of harmful microbes is a good thing but the removal of beneficial microbes brings instability in the environment. These beneficial microbes helps in the recycling of nutrients for the plants present there. So the negative effect of chemical is that it also effect the beneficial microbes which are necessary for the ecosystem.

Answer:

By absorbing the sun’s blue and red light, chlorophyll loses electrons, which become mobile forms of chemical energy that power plant growth.

Answer:

Mass = 40 kg     Weight = 64 N

Explanation:

Mass does not change.  40 kg on Earth = 40 kg on the moon = 40 kg on Saturn, etc.

Weight = Force = Mass*Acceleration

So, Weight = 40 kg * 1.6 M/s^2 = 64 newtons

Answer:

Haven't done this in a while but here goes: Top left FF - Top right Ff - Bottom left fF ( or Ff?)- bottom right ff.

Explanation:

Freckles are dominant trait so Capitalized letter F ( i chose "F" because the question told me to choose a random letter to use in this problem). Yet, one son doesn't have them so there must be a presence of a recessive allele (hence, little f). This all means that both parents have one dominant allele and one recessive allele. Each one has "Ff". So then you fill it in. The first gamette of each is "F" so when the box asks for Gamette 1 you put an F and when it asks for a gamette 2 you put in a "f". Now the bottom right might be "Ff" just because you would follow the traditional order of putting the dominant allele first but, I wasn't sure. Hence the "Ff/fF" I put. That itslef wouldn't be the final answer but two options of what I believe it would be. You might know which to choose as you've seen it in class but yeah.

Here again, I haven't done this in a REALLY long time so take this with a literal grain of salt and if it doesn't line up with what you've learned in class, please disregard this response!

Explanation:

Energy is transferred between organisms in food webs from producers to consumers.

The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Answer:

Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.

In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.

Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Numerous scientists contributed to the development of the cell theory since it required the cooperation of numerous researchers to acquire evidence from various disciplines of study.

A key idea in biology is the cell theory, which holds that all living things are made up of cells. It began to take shape as microscopy and biological knowledge advanced throughout time.

Numerous scientists, including Rudolf Virchow, Matthias Schleiden, Theodor Schwann, and Anton van Leeuwenhoek, performed important roles.

Thus, these scientists' broad knowledge in fields like microscopy, botany, zoology, and medicine enabled them to put together a thorough understanding of cells, which led to the development and improvement of the cell theory.

Answer: 50%

Explanation:

I got 50% because the purple and white is a 50/50 chance. Meaning that the white is 50% and the purple would be a 50%.

The large P is Horizontal and all the small p are on the top. The large P is dominant, while small p is not. If there were 2 big P then all flower crosses would be purple.

1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.

2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".

3.) While sea breezes occur during the day, land breezes occur at night.

4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.

5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.

Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.

2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.

3.) The sea breeze occurs during the daytime.

4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.

5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.

Humidity likes to hold onto heat. The less humidity in the air the more the heat can be dissipated.

Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On the weather reports, humidity is usually explained as relative humidity.

Humidity is the measure of the level of moisture vapor suspended in the air around you. Although you can't see it, it's still there. The ideal relative humidity for health and comfort is somewhere between 30-50% humidity.

When the humidity level increases along with temperature, it's harder for the moisture to dry, and you feel warmer. When the air indoors is 75 degrees and the humidity is 30 percent, the air actually feels like 73 degrees.
