Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Explain the flow of energy from the sun to sunflower and then on to a cardinal that ate the sunflower seeds. How did the energy help all three of these organisms to stay alive?
Answer:
The energy from the sun moved in the form of Light radiation, which the Sunflower then used in a process called photosynthesis. They use this to make sugar and that's what grows the seeds. This is then eaten by the cardinal, who uses it as chemical energy to fuel itself. The flower is growing from the energy that the sun gave off, and the cardinal recieves energy from the seeds.

HELP!!! Amino acids are small molecules that make up proteins.
What information do genes determine when building proteins?
choose all that apply:
the amino acids that are used.
the order of the amino acids.
the location where the protein is built.
the total number of amino acids.
Answer:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.

The National Aeronautics and Space Administration (NASA) has designed many robots to help astronauts explore space. Some robots drive around like cars, some are just large arms, and some look like humans. All of these robots can accomplish tasks in space that are too difficult or dangerous for astronauts to do alone.
2
The most famous NASA robots are called the Mars rovers. According to NASA, the wheeled rovers are part of the Mars Exploration Program, “a long-term effort of robotic exploration of the red planet.” The newest rover, Curiosity, landed on Mars in August 2012. The size of a small car, Curiosity carries advanced equipment to analyze the soil and air on Mars. Curiosity has made many exciting discoveries about the planet's environment. Most importantly, it discovered that Mars contains the right ingredients to support life, including carbon, oxygen, and water. Curiosity has also found that astronauts on Mars would be exposed to dangerous levels of radiation. This discovery will help NASA protect its astronauts when they one day travel to Mars.
3
NASA is also building other robots. For example, the Robonaut2 looks like the upper half of a human. The human hand is a very complex and useful tool. It might seem easy for a person to press a button, grasp and lift an object, or turn a knob, but these tasks are very hard for a robot. However, a robot that could perform these tasks would be very useful to astronauts. The Robonaut2 is now being tested at the International Space Station (ISS). Eventually, NASA wants to add legs or wheels to the Robonaut2, which would allow it to move around outside the ISS.
4
Another robot on the ISS is a massive arm called Canadarm2. It can do repair work and transport objects too big for humans to move. Canadarm2 has even caught the Hubble telescope to allow astronauts to repair it. As technology develops, NASA will increasingly rely on robots. They will guide astronauts in new places, give them medical care, and do dangerous work for them. With their special equipment and considerable strength, robots can help humans explore new worlds.

EXPLAIN THE ANSWER AND I WILL GIVE BRAINLIEST:
Answer:
a
Explanation:
it helps them photosynthesize
Answer:
A
Explanation:
Plants rely on energy from sun rays to feed itself. Plant's leaves spread out and collect energy from the sun for the plant (A plant's leaves and roots are kind of like it's mouth, leaves for sun rays ; roots for water) So, to maximize the amount of energy the plant receives, the plant bends the leaves towards the sun.
P.S.: It's ok if you think I'm wrong.
(WILL GIVE BRAIN)There is a low-pressure system moving in from the South, and a cold front moving in from the North. Both systems are expected to reach your area on the same day. Prepare a short news report to brief viewers on what the forecast looks like in the coming days.
Answer:
Cold fronts move faster than warm fronts because cold air is denser, meaning there are more molecules of material in cold air than in warm air. ... Because air is lifted instead of being pressed down, the movement of a cold front through a warm front is usually called a low-pressure system.
Explanation:
Explain why a food web is a more realistic model of energy flow than a food chain.
No links or jibberish!
Answer:Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas. La transferencia de energía entre niveles tróficos es ineficiente, con una eficiencia típica de alrededor del 10%.
Explanation:
Answer:
Food chains only show one path by which energy can move through an ecosystem. Because most organisms eat a variety of things, they are part of many food chains. A food web shows the interconnected food chains in an ecosystem and the multiple paths through which energy can move, which is why it is a more realistic model for showing energy flow.

Think about the climate that you live in. How does your climate relate to the air and ocean currents?
Answer: Ocean currents can affect the climate of nearby land. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer. Places near the ocean experience moderate temperatures year round due to the fact that water has a high specific heat, meaning that it cools and warms slowly. Places further inland have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Ocean currents influence rainfall patterns. Warm, moist air associated with warm ocean currents increase precipitation.
bye im too lazy for this
Answer:
If you are closer to a ocean current, you can experience moderate temperatures year round because the water has a specific temperature. his would make the land near the ocean take longer to heat up and cool down. Ocean currents affect the climate of the land near it. They move warm and cold water currents around the globe. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer. Places further from the coast have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Of course weather you are closer or further also changes things. If you are closer to the equator you have higher temperatures, and the further away you get, the colder it gets. Ocean currents also influence rainfall patterns. Perspiration normally happens near the ocean, so the air will be humid and moist due to the water in the air going up to make clouds. If you are near a warm air current, you will get more warm ail on top of that. However, if you are closer to a cold air current it will be colder. If you are close to both, you are likely to experience tornadoes and hurricanes due to the warm and cold air currents coming together.

Please write 1–2 sentences relating the water cycle and wind to temperature and precipitation.
Quickly please
Answer:
Some examples of precipitation include rain, snow and hail. Precipitation is a part of the water cycle. Once the rain leaves the clouds, it forms a stream/ river to get to a lake or ocean. From there transpiration takes place to make those droplets form clouds. The sun mover the clouds, and we get back to transpiration.

Answer:
It should be
A. The biodiversity of these areas will decrease.
The biodiversity of these areas will decrease describes the MOST LIKELY impact of the replacement of rain forest plants with nonnative grasses. thus option A is correct.
What is biodiversity ?
Biodiversity can be defined as the total number of living organisms present in a particular area dependent upon different factors like habitat, competition among species, resources, and climatic conditions.
There are three types of biodiversity such as genetic, species, and ecosystem diversity.
In a specific area the increase in human population makes a problem for the biodiversity with the increase in population and it comes a need to convert natural habitats to land for human consumption and shelter.

“Coronavirus Is Mutating”, what could be the reason for it? (Research) and tell your answer in your own simple words
Answer:
Explanation:
Coronavirus is mutating because as more people are getting the virus, that gives that virus a change to mutate and form a different strand. When a virus hijacks a person cells, it causes that cell to start producing the DNA of the virus, but because human cells where not made to produce the DNA of a virus, mistakes happen, thus slightly changing the DNA of the virus which can then cause a new strand of the virus to appear.
