What is coal used for
Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.

What happens to macromolecules from food during digestion?
What atoms make up sugar molecules, amino acids, and fatty acids?
What do you notice about the atoms that make up these molecules?
How are these atoms used to make new molecules? What types of molecules are
made?
Answer:
In chemical digestion, enzymes break down food into the small molecules the body can use. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across cell membranes./ monomers/when you eat you take in molecules/When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms/ of bond: ionic bonds, covalent bonds, or metallic bonds./Proteins.

How are ferns, gymnosperms, and angiosperms alike? They are all vascular plants. They depend on water for fertilization. They all produce seeds. Reproduction depends on birds, bees, and other animals.
Answer:
The correct answer is ''They are all vascular plants''.
Explanation:
Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.

they all vascular plants

Which of the following statements is true about the Big Bang Theory?
1 point

expanding
O
Everything in the universe was created when the big bang occurred and the universe is
staying in the same location.
O The sun is the center of our solar system.
The Earth is the center of out solar system.
Kk
Everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).
What is Big Bang Theory ?The Big Bang theory is an attempt to explain what happened at the beginning of our universe. Major discoveries in Astronomy and Physics have explained that our universe actually had a beginning. Before that moment there was nothing and after that jump there was something which is our universe.
According to the widely known theory, our universe sprang into existence as "singularity" which goes back around 13.7 billion years ago. Singularities are basically zones which flout our knowledge of physics. They are assumed to be present at the core of "black holes."
Black holes are regions of enormous gravitational pressure. The pressure is assumed to be so extreme that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of interminable density are called "singularities."
Thus, everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

A(n)\ is an area of the planet that shaves similar conditions of climate, fauna (animal life), flora (plant life) and geography .
1.biome
2.environment
3.habitat
4.ecosystem
Answer: A BIOME is an area of the planet that shaves similar conditions of climate, fauna (animal life), flora (plant life) and geography . The correct option is 1.
Explanation:
BIOME is defined as large natural terrestrial ecosystems which shares similar conditions of climate and consists of plants and animals that equally have common characteristics with their environment. The word terrestrial is used because plants form the bulk of the community in an ecosystem. The type of vegetation in a biome is largely determined by climatic factors, especially rainfall and temperature. Regions throughout the world which have similar climates have similar biomes. This causes zones of different biomes to occur from the equator to the Arctic and to the Antarctic. For example,
--> in equatorial and tropical areas where temperature is high all the year round tropical forests occur;
--> in temperate regions coniferous and deciduous forests occur;
--> while treeless plains (tundra) are found in the cold arctic regions.
Climates also changes with height above the sea level.

Why the Chimpanzee's diploid number is 24 instead of 48.
I am not sure if the following table supposes me to write 2 (N) on here...
Thank you very much
Answer:
It has 24 pairs and 48 number of chromosomes.
Explanation:
The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.
Which describes how scientific models are used? (2 points) Select one: a. They allow scientists to make predictions. b. They prevent scientists from performing experiments. c. They make it easier for scientists to avoid using data. d. They prevent people from criticizing the work of scientists.
Answer:
A-They allow scientists to make predictions
Explanation:
Scientific models aid scientists in performing experiments by allowing them to better understand their subject. This rules out B. C and D simply do not make sense, as all good experiments should generally use data to prove the validity of their points and there’s no real way to prevent criticism. Hope it helps :)

Changes in ____ result in a change in protein structure which alters the ____-type of the organism and MIGHT increase _____.
Answer:
DNA, genotype and resistance.
Explanation:
Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.
