Answer:
alleles-one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
dominant- The dominant allele of the gene is inherently dominant,so it hides the presence of the recessive allele
heterozygous-having two different alleles of a particular gene or genes.
homozygous-a particular gene that has identical alleles on both homologous chromosomes
recessive-A recessive gene is a gene that can be masked by a dominant gene
Answer: C). A tsunami would decrease abundance by causing physical damage to the organisms and their ecosystems.
An intertidal zone is also known as littoral zone. It is the region which is covers the foreshore and seabed. This region is exposed to the affects of tides. This region is highly vulnerable to tsunamis. The tsunami will disturb the habitat of organisms living in intertidal zone. Therefore, will result in decrease in abundance of aquatic organisms.
The correction option is VENTILATE THE AREA.
In order to reduce indoor air pollution, the best thing to do is to ventilate the area. Ventilation involves provision of fresh air into a room in order to flush out and eliminate indoor pollution.
photosynthesis as a whole takes place in the organelle called chloroplast but light reaction takes place in the chloroplast stroma
The eye spot and the chloroplasts work together to help the euglena survive because the eye spot senses the light and the dark. Since euglena need to do photosynthesis in which uses light energy to make usable energy, to get food, the eye spot will tell the euglena where to move in order for it to be able to do photosynthesis.
