Answer;
-the continental shelf, slope, and trenches;
The continental shelf, slope, and trenches are the structures on the ocean that are equivalent to the mountains on land.
Explanation;
-Continental shelf is that shallow part of the ocean floor that begins at the shoreline and gently slopes underwater to an average depth of about 430 feet. It is normally covered with thick layers of sediment.
-Continental slope begins at the edge of the continental shelf and plunges down to depths of over two miles and are covered with thick layers of sand, mud and continental shelf.
-Ocean trenches are very deep and similar to canyons on land.
B) they are having a positive impact on the environment by acting as decomposers.
C) they are having a negative impact on the environment by acting as decomposers.
D) they are having a predatory impact on the environment by acting as decomposers.
The correct answer is option B) i.e. they are having a positive impact on the environment by acting as decomposers.
By acting as decomposers beetles are helping in recycling of nutrients between biotic (organisms) and abiotic factors (enviroment). So, it may be considered as positive impact on the environment. Decomposers play a very important role in food chains and food webs. They breakdown biomolecules and liberate the micronutrients and micronutrients as inorganic molecules back to the environment. These inorganic molecules are used by plants once again to synthesize biomolecules. This is how nutrient cycle operates with the help of decomposers. For example, protein molecules of dead and decaying matter are broken down by decomposers to liberate nitrogen gas to the environment which is utilized by leguminous plants to make protein molecules again.
B. Viruses have no RNA.
C. Viruses have no metabolism.
D. Viruses have a protein shell that protects them.
Answer:
If the number of solute (sugar) in the environment is less compared to the solute particles present in the inside such condition is called as hypo-tonic conditions.
Explanation:
Then water will move outside the cell.As the solution in which the cell is placed also has a higher concentration of water than the cell does, which makes Osmosis to draw water out of the solution and into the cells. As a result, plant and animal cells both appear more plump when placed in a hypo-tonic solution.

Answer:
False
Explanation:
Chaparral biomes are found majorly in five regions of the world namely-
Mediterranean Basin, southern California, South Africa, Chile, Australia.
All together they constitute only two percent of the land on earth. However, they contains nearly twenty percent of world’s plant diversity.
This biome has varied geographical and topographical features ranging from extreme dry summers to wet winters which allows varied fauna species to flourish.
Answer:
Gregor Mendel is remembered as the "father of modern genetics" for his pioneering work on pea plants in the 19th century. He conducted a series of experiments to study how traits are inherited from one generation to the next, and his discoveries laid the foundation for our understanding of genetics.
Mendel's most significant contribution was his formulation of the laws of inheritance, now known as Mendelian inheritance. He proposed that traits are passed down from parents to offspring in discrete units called "genes." Through his experiments, he identified dominant and recessive traits and showed how they can be inherited independently of each other.
One of Mendel's famous experiments involved crossbreeding pea plants with different characteristics, such as flower color or seed texture. By carefully observing the resulting offspring and analyzing the patterns of inheritance, Mendel was able to deduce the basic rules of heredity. He found that traits are determined by pairs of alleles, with one allele inherited from each parent.
Mendel's work was not initially recognized during his lifetime, but his findings were rediscovered and widely accepted in the early 20th century. Today, his laws of inheritance are fundamental to the field of genetics and are taught in biology classrooms around the world.
In summary, Gregor Mendel is remembered for his groundbreaking experiments with pea plants, which led to the discovery of the laws of inheritance and laid the foundation for modern genetics. His work revolutionized our understanding of how traits are passed down from one generation to the next
