Answer:
Student 2 is correct!
Explanation:
The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in Kashmir, are the result of an ongoing orogeny — the result of a collision of the continental crust of two tectonic plates. This immense mountain range was formed by tectonic forces and sculpted by weathering and erosion.
Answer:
C. a population in Florida
Explanation:
Population is described as a group of interbreeding organisms of the same species living together in an area. Here, all the rattlesnakes can breed with each other which makes them a population of rattlesnakes. The report dealt with all the attributes of a population like breeding rate and average size. There are more attributes which can be considered in a population like birth rate, mortality rate etc.
A community is a group of organisms of different species which interact with each other and the surrounding environment. A biome is a collection of ecosystems which reside in a big area with similar environmental factors.
Contraction is the answer
Answer:
The X-shaped structure is made of strands of DNA.
Explanation:
The chromosomes are thread-like structures located in the nucleus of each cell in the body. In a human cell, there are 23 pairs of chromosomes found in the nucleus. Each chromosome is made up of strands of DNA tightly coiled many times around proteins called histones which gives support to its structure.
The chromosomes are X-shaped and are observed only in a cell undergoing division by mitosis or meiosis. Each of these X-shaped chromosomes consists of two identical sister chromatids. The sister chromatids are connected to each other by a region of the chromosome called the centromere. The centromere are located around the depression point of the chromosome which divides the sister chromatids into two regions: long arm called the q arm and a shorter arm called the p arm. During mitosis, spindle fibers attach to this region, and they eventually pull the sister chromatids apart to form two separate chromosomes, one for each daughter cell.
Answer:
Similarities in their DNA sequences.
Explanation:
As humans have 46 chromosomes, Chimpanzees have 48,So this is best shown by chromosome numbers not by other features.
