List 4 different organisms from the same food chain in the order of how the energy flows.
Answer:
Worm, Bird, Snakes, Hawks.
Explanation:
Hope this helps in anyway,
Worm, Bird, Snakes, Hawks are the order of how the energy flows.
What is Food chain?
Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism.
Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Plants, which convert solar energy to food by photosynthesis, are the primary food source.
Because energy, in the form of heat, is lost at each step, or trophic level, chains do not normally encompass more than four or five trophic levels. People can increase the total food supply by cutting out one step in the food chain.
Therefore, Worm, Bird, Snakes, Hawks are the order of how the energy flows.

Stephan’s mother is a mineralogist, and sometimes she brings home samples to study. Stephan observesand compares these minerals. He knows minerals form in several ways. He is especially interested in the minerals that form from volcanic activity and the kinds of crystals they form. What determines crystal size in minerals formed by lava or magma?
A. the kind of mineral that formed
B. the amount of material available
C. the rate at which the minerals cooled
D. the materials in the lava or magma
The rate at which the minerals cooled determines the crystal size in minerals formed by lava or magma. The correct option is C.
What determines crystal size in minerals?The solution is extremely saturated with some minerals, crystals form as magma cools. The crystals are quite tiny because they did not have much time to form if the magma cooled quickly. The crystals have ample time to form and become huge if the magma cools gradually.
The rate at which the minerals cooled Crystal size in minerals formed by lava or magma is primarily determined by the rate at which the minerals cooled.
When lava or magma cools slowly, it allows crystals to grow larger. Conversely, when it cools rapidly, crystals have less time to grow and thus remain smaller.
Therefore, the correct option is C.

Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.
Answer:
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.
Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.
What are convection currents?Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.

Which of these statements best describes the connection between biodiversity and evolution?
The more biodiversity an area has, the greater the chances of new species arising.
If biodiversity is high, then more predation will take place, preventing species from evolving.
Without a lot of biodiversity, organisms are more likely to survive, so they have more time to adapt.
Evolution depends upon low biodiversity to keep population sizes down, which increases numbers of genes.

Genetic engineering because the genes of the animal would be modified
Genetic engineering because it is always helpful for the environment
Cloning because offspring that are exact copies are produced
Cloning because offspring would be produced in a few hours
Answer:
the 3rd option: Cloning because offspring that are exact copies are produced
Explanation:
Biotechnology is a field of science that comprises biology combined with technology. It utilises the living system with the technology to build products.
The correct answer is:
Option C. Cloning because offspring that are exact copies are produced.
This can be explained by:
Cloning is a mode of reproduction in which the replica of the parent is produced as offspring.The genetic content of the offspring is the same as that of the parent. Hence all the traits and the characters remain preserved.Therefore, for deliberately producing the endangered species cloning technique can be employed.

Photosynthesis is to oxygen as:
A. Oxygen is to carbon dioxide
B. Cellular respiration is to carbon dioxide
C. Cellular respiration is to oxygen
D. Cellular respiration is to enzymes
Answer: It is C but if it was multiple choice it would be both B and C.
Explanation: Allow me to explain my reasoning. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). And allow me to explain the answer C. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Therefore, it can be both B and C if it was multiple choice. Thank you for your time.
Photosynthesis is to oxygen as Cellular respiration is to carbon dioxide. Thus option B is correct.
what is photosynthesis ?The process in which sunlight energy is used by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast which has its own DNA, genes and hence can synthesize their own proteins, photosynthestic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.
plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts
Antennae is made up of 100 to 5000 pigment molecules that capture light energy from the sun in the form of photons, Reaction Centers where photosynthesis occur.
