The Nervous System is one of the first systems to develop during the embryonic period. Why do you think this is?
The process of neurulation, which takes place between weeks three following conception, allows the embryo to form the components that will one day become the nervous system. It's important to regulate body functions.
What is embryonic nervous system?The neural crest gives rise to the development of structures in the periphery. At this stage, the early nervous system resembles nothing more than a straightforward tube. It begins from the front of the embryo and continues all the way around to the back. Beginning at day 25, the anterior end will develop into the brain, while the posterior portion will develop into the spinal cord.
The brain is the organ that is responsible for controlling every function of the body. The brain is connected to the rest of the body through the spinal cord, which travels down the back. It contains nerves that are similar to threads and branch out to every organ and area of the body. Messages are transmitted to and from the brain via this network of nerves, which connects the brain to various regions of the body.

What is the origin of the energy that all organisms need to carry out life functions?
A. food
B. producers
C. plants
D. the Sun
Answer:
D. The Sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. This process begins the flow of energy through almost all food webs. Food is sunshine stored in chemical form. Organisms use the stored energy in food to fuel all living processes.
Which of the following stages of complete metamorphosis involves a period of continuous
eating?
A. pupa
B. adult
C. egg

Answer: I think it's A
Explanation: Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.

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.

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.

many species of animals carry an allele for albinism (lack of pigmentation). Albinos are usually pale or white in color. explain why the allele for albinism is present at la lower frequency than the allele for having pigments. what conditions would be necessary for the albino allele to be more frequent?
Answer: breeding an albino with an albino and let the babies lose and repeat
Explanation:
The allele for albinism is present at a lower frequency because it is not adaptive for most of the environments where humans live.
What is an allele?An allele is a gene variant that confers a certain fitness to an individual depending on the environment where this organism lives.
Adaptive alleles are in high frequency because they confer an adaptive advantage.Non-adaptive alleles are present in low frequency because they do not confer an advantage.In conclusion, the allele for albinism is present at a lower frequency because it is not adaptive.

Is global warming in a tundra biome secondary or primary succession? Why? PLEASE ANSWER
Why do organisms with one color produce few offspring than those with multiple colors?
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 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.
