Answer: They grow more slowly, reproduce less, and populations decline. ... As predator populations increase, they put greater strain on the prey populations and act as a top-down control, pushing them toward a state of decline. Thus both availability of resources and predation pressure affect the size of prey populations.

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.

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.

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.

Give an example of how a random mutation in an organism could give it an environmental edge over other members of its species.
Do changes in the environment CAUSE mutations or are they already present in the gene pool of a population? Explain.
Answer: The mutation could cause it to adapt to the environment better, pick up food better, or even become almost totally different to the others because of how different it is. changes in the environment determines which organism lives. Some mutations seem to happen spontaneously without any outside influence. They can occur when mistakes are made during DNA replication or transcription. Other mutations are caused by environmental factors. Anything in the environment that can cause a mutation is known as a mutagen. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. ... Mutations contribute to genetic variation within species.

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.

1. Describe the flow
of energy in a
marine food web.
Include at least 5
organisms.
2. Describe how
removing an
organism from a
food web can
impact the entire
ecosystem.
Answer:
1. A food chain is a single pathway connecting a producer with several levels of consumers. In a typical marine food chain, dinoflagellates convert energy from sunlight into food through photosynthesis and store it in their tissues.
2. They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.
have a good day!
The flow of energy in a marine food web include the following:
Plankton⇒shrimp⇒ salmon⇒ seals⇒ whales
What is a food web?A food web comprises of food chains which are interconnected and also
explains the flow of energy between organisms in the ecosystem.
In the marine ecosystem, the plankton which are plants are the primary
producers while the whales are the tertiary/quaternary consumers as they
are at the top of the web.
Removing an organism from a food web can impact the entire ecosystem
by reducing the number of organisms and options available for food. It can
increase or decrease the population of organisms which they have direct
relationship with.

Use the drawing tool to modify the model, showing the direction of prevailing winds in the Northern Hemisphere and convection currents. Label hot and cold air on your convection currents.
Answer:
Image down below will be correct.
Explanation:
The direction of prevailing winds and convection currents in the Northern Hemisphere and how to label them.
What is westerlies?Prevailing winds in the Northern Hemisphere generally blow from west to east due to the Coriolis effect. This means that winds move clockwise around areas of high pressure and counterclockwise around areas of low pressure. The prevailing winds are known as the westerlies.
Convection currents in the Northern Hemisphere are driven by temperature differences between the equator and the poles. Warm air rises at the equator and moves towards the poles, while cold air sinks at the poles and moves towards the equator.
This creates a convection current that moves from the equator to the poles in the upper atmosphere and from the poles to the equator in the lower atmosphere.
To label hot and cold air on your convection currents, you can draw arrows to show the direction of movement and label them accordingly. Hot air rises at the equator and cold air sinks at the poles, so you can label the arrows with "hot" and "cold" respectively.

Label the angle of incidence and the angle of reflection in the Figure below.
In the picture, I have highlighted the angle of incidence blue and the angle of reflection red.
hope this helps :)
Angle of incidence refers to the angle between the incident ray and the normal, while angle of reflection represents the angle between the reflected ray and the normal.
Thus, angle of incidence is the angle formed by the incident ray which is the light beam flowing in and the normal which is a line perpendicular to the surface at the point of incidence. The angle of reflection, denoted by the symbol r, is the angle between the normal and the reflected ray of light (the ray of light that bounces off the surface).
The angle of incidence and angle of reflection are equal, according to the law of reflection. The angle at which light reaches a surface and the angle at which it reflects off of it are identical. This fundamental concept describes how light interacts with surfaces, such as mirrors or smooth objects.
