A group of college students working on a project on bio-gas have found some bacteria in the bio-gas plant. These bacteria can utilize methane as their source of energy and do not need oxygen for their survival. The kind of bacteria is Archaebacteria.
Fossils are just skeletons that are found in the ground, left from generations ago. Such as Dinosaur Skeletons.
Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.
The first is when an animal dies it decomposes and it releases carbon dioxide. the second is when an animal breaths in and out they release carbon dioxide into the atmosphere
Answer:
El statement that say Direct observation is the simplest and most effective method to determine population size is false.
Explanation:
Simple observation results in an inadequate method for estimating the size of a population, especially if it is very large and mobile. A simple and adequate method consists of counting individuals within a population, with some limitations.
Currently, in large populations, it is common to divide an area occupied by a population into quadrants, count individuals, and then extrapolate the data to the actual dimensions of the space occupied by that population.
