Oceanic crust to continental crust collision led to the formation of the Andes Mountains. Therefore, the correct option is B.
The collision between the oceanic Nazca Plate and the continental South American Plate was the primary reason for the development of the Andes Mountains. The collision of oceanic crust with continental crust occurs when oceanic crust subducts under continental crust. The subduction of oceanic crust beneath continental crust resulted in the uplift and formation of the Andes Mountains through volcanic activity and crustal deformation.
Therefore, the correct option is B.

Answer:
B
Explanation: Oceaninc to continental as the oceanic crust subducted under the continental
1.) Leaves
2.) Stems
3.) Branches
Answer: The correct answer is 1) leaves.
Cactus is a desert plant that possesses thick, enlarged, and leafless stems that are covered with sharp spines or spikes. These sharp cactus spines are the modified leaves that provide them an extra advantage for surviving in desert.
Cactus spines provide protection against predator (as they are very sharp) and prevent the loss of water by reducing the flow of air near the cactus and giving them some shade.
(2) most changes from generation to generation are the result of mutations
(3) part of the population of organisms always remains stable
(4) different traits inherited by offspring have different survival value
Answer:
Option B, most changes from generation to generation are the result of mutations
Explanation:
Through the process of evolution, an individual changes from one generation to other generation. These variations are caused by genetic changes.
Genetic variations are caused by -
a) Genetic mutation
b) genetic recombination
Genetic variation leads to alteration of gene or protein function due to which differences traits arises in an organisms. Thus , it can be said that genetic mutation brings variation in structure and thus leads to evolution of any species.
As long as generations of individuals with the newly developed trait continues to mate and reproduce, new trait becomes common in a population.
Hence, option B is correct
b. 4 bases at a time in the same direction.
c. 3 bases at a time and the direction varies.
d. 4 bases at a time and the direction varies.
The genetic code is read 3 bases at a time in the same direction. These 3-base sequences in DNA are referred to as codons and each one codes for a specific amino acid. This is essential during the process of protein synthesis.
The genetic code is indeed always read 3 bases at a time in the same direction, which simply means, the answer is 'a. 3 bases at a time in the same direction'. This 3-base sequence in DNA is called a codon. Each codon is responsible for coding a specific amino acid. For example the codon UGA signals to stop protein synthesis. Genetic code reading is a vital part of the protein synthesis process, specifically during the translation phase where the genetic code in mRNA is translated into a sequence of amino acids to form a protein.

Two different herbivores can share the same plant resource by consuming different parts of the plant, or feeding at different times. Some plants and herbivores share a mutualistic relationship where the plant benefits from wider seed distribution. The balance in a shared habitat can also be maintained with one herbivore species being more efficient at gathering food.
In a shared habitat, two different herbivores can exist harmoniously and share the same plant resource through differentiation in their feeding habits or adopting different times for feeding. Herbivory describes the consumption of plants by insects and other animals. For instance, one herbivore might consume a particular part of the plant, such as the leaves, while another might eat another part like the fruits.
The relationship can also be mutualistic, benefitting both the herbivores and the plants. With herbivores feeding on them, plants get a chance to spread their seeds wider through the herbivores' excretion or the seeds attaching to their bodies.
Food competition is also a crucial aspect of the relationship between herbivores in a shared habitat. In certain cases, one species might be more efficient in gathering food than the other, but it doesn't necessarily lead to the extinction of the less efficient species, as there can be a balance established over time.
