Answer:
Evolution works independently of natural selection
Organisms best suited for environment survive and reproduce statement accurately describes natural selection
Explanation:
Natural Selection: Organism adapts itself to the particular environment to survive and reproduce.
The theory of Natural selection was popularized by Charles Darwin. He explained that organisms evolved, they can survive when they get adapted better to the environment.
Natural selection is also called the'' survival of the fittest''. The organism which gets adapted to the environment will survive.
The more desirable characteristic will pass from parents to offspring.

sphere do you think is the most important to study and why your answer should include information about all four spheres (hydrosphere lithosphere atmosphere and biosphere)
Answer:
HYDROSPHERE
Explanation:
The lithosphere is the solid outer portion of earth. It includes the crust and a small portion of the upper mantle. The rocks present in this region are determined which are hard and undergoes deformation due to the stress that acts on it. The region has been explored and sufficient data has been acquired.
The atmosphere is defined as the gaseous envelope that surrounds the earth. The different layers of atmosphere has been constructed depending upon its height and temperature. The composition of atmosphere is also identified that are present in a definite amount. This amount can either increase or decrease due to the changes in the earth's surface.
The biosphere is the region that includes the hydrosphere, atmosphere and lithosphere where life occurs and interacts between them. Sufficient study has been made regarding this zone and were able to understand how life occurs depending upon the various factors.
The hydrosphere refers to all the water bodies on earth, including the glaciers and the ice bergs.
The terrestrial areas have been explored easily because it is possible for a person to visit those sites but it is not possible to go at a deeper depth to study the structure and the components of the deep water bodies. Although, much of the information has been regarding this sphere, but still the deep water portion such as the deep sea trenches are yet to explore. It is not possible because at this depth, the pressure is extremely high and lift is normally difficult to exist at this pressure condition. But there are some animal and plant species that can grow and survive at this condition.
So, much more is needed to study regarding the hydrosphere.
The most important sphere to study may vary by perspective, but all four spheres, the lithosphere, hydrosphere, atmosphere, and biosphere, are interdependent, influencing Earth's climate, geography, and life.
Understanding the different spheres of Earth is crucial because they are deeply interconnected and collectively influence the planet's climate, geography, and life. The four main spheres are the hydrosphere, lithosphere, atmosphere, and biosphere. The lithosphere includes solid rock, soil, and minerals. The hydrosphere encompasses all forms of water on the planet. The atmosphere refers to the layer of gases surrounding the Earth, and the biosphere comprises all forms of life and their interactions with the other spheres.
Each sphere is important in its own right, but if we must consider which sphere is the most crucial to study, it could vary depending on the perspective and context. The hydrosphere is often emphasized due to its essential role in the water cycle and life support, interacting dynamically with the atmosphere, lithosphere, and biosphere. This interaction includes fundamental biogeochemical cycles, such as those for water, carbon, and nitrogen, which are critical for life on Earth.
However, determining which sphere is the most important is subjective and largely depends on what aspect of Earth's systems one considers most vital. The lithosphere provides the foundation for habitats and is a source of valuable resources, the atmosphere is crucial for climate and weather patterns, the hydrosphere is indispensable for all life, and the biosphere is the sum of all ecosystems. The study of any single sphere is incomplete without considering its interactions with the others.
Which of the following functional groups contains only carbon, hydrogen, and oxygen? A) carboxyl group B)amino group C)sulfhydryl group

which of the following parts of a nuclear power plant is turned on by steam
A.Control rods
B.Ractor vessel
C.Turbine
D.Generator
Answer:
Option (C)
Explanation:
A nuclear power plant is considered to be a thermal power station where the main source of heat is the nuclear reactor. Here, energy is released in the form of heat that helps in generating steam. This steam then initiates the motion of the turbines that are connected to a generator. These turbines when rotates produce electricity.
These nuclear plants are less costly and they do not emit any kind of pollution. They are very efficient to use but has certain disadvantage, that the waste materials it releases contain some amount of radioactive element in them and are difficult to dump.
Thus, the turbines in a nuclear power plant is turned on by the steam.
Hence, the correct answer is option (C).

which organelle of a prokaryotic cell contains genetic information? A.ribosomes B. nucleus C. nucleoid D. cell membrane
The right option is; C. nucleoid
Prokaryotic cells are simple cells that lacks a definite nucleus and some membrane bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm and ribosomes.
Nucleoid is an organelle of a prokaryotic cell that contains genetic information.
Further Explanation Living organisms are classified as either eukaryotes or prokaryotes. Eukaryotes Eukaryotes are living organisms that contain a nucleus and other membrane bound organelles. The function of the nucleus being storage of genetic materials and also controlling all cellular activities. Eukaryotes are either single celled or multicellular for organisms such as plants, animals, and fungi. Prokaryotes Prokaryotes are organisms that lack a nucleus and other membrane bound-organelles such as ribosomes, Golgi apparatus, endoplasmic reticulum, etc. Genetic information in prokaryotes is contained in a nucleoid which is a concentration of DNA that lacks an enclosing membrane. Nucleoid contains large circular DNA that has genes that are required for the survival and reproduction of the cell. Other Cellular organelles. Nucleus Nucleus is a type of cellular organelle found in eukaryotic cells whose function is to control all the cellular activities undertaken by the cell. Additionally, the nucleus house the DNA which carries the genetic material of an organism. Mitochondrion This is one of the cell organelle inside a cell. It is referred as the powerhouse of the cell, as it is where energy to drive all cellular activities is generated through the process known as cellular respiration. Ribosomes These are organelles where the synthesis of proteins takes place through a process known as translation. They are found in the cytoplasm, either freely suspended or attached to rough endoplasmic reticulum. Cell membrane It is a structure that encloses the cell contents in the cytoplasm from the external environment. It’s functions is to control materials entering in and out of the cell through selective permeability.

What is one way that early scientific practice differed from modern scientific practice? Early hypotheses were not based on observations. Early hypotheses were not tested by experimentation. Early hypotheses were formed from scientific questions. Early hypotheses were influenced by creative thinking.
Early hypotheses were not tested by experimentation.
One way early scientific practice differed from modern scientific practice is that early hypotheses were not tested by experimentation. In earlier times, many ideas were often developed based on philosophical reasoning, deductive logic, or theoretical speculation without the rigorous experimentation and empirical testing that are central to modern scientific methods.
Over time, the emphasis has shifted to the use of controlled experiments and systematic observation to test hypotheses and validate scientific theories.
