Obsidian is an extrusive rock that is formed when magma from underneath the Earth's crust breaches and becomes lava. Once the lava starts cooling, it solidifies and elements are frozen, giving the rock its glassy appearance.
A, I believe. Because after collecting you need to analyze in order to do many other steps. Also all the other answers are something before collecting data
The given question is incorrect. The correct question is:
Which of the following is true about a plant with the genotype AABbcc?
a. It is heterozygous at two loci.
b. It is homozygous at two loci.
c. It is triploid.
d. It will not express the recessive c allele.
e. It has recessive alleles at three loci.
Answer:
b. It is homozygous at two loci.
Explanation:
When an organism has two identical alleles of a particular gene, it is said to be homozygous for that gene. The given genotype "AABbcc" has a dominant allele for "A" and the recessive allele for "c". It is homozygous for these two genes but is heterozygous with respect to "B". The presence of three complete sets of chromosomes makes the organisms triploid. The given genotype carries two alleles for each gene and therefore, it is diploid.
Answer:
<em>What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.</em>
Explanation:
<em>Endosymbiosis is important because it is a theory that explains the origin of chloroplast and mitochondria. It is also a theory that explains how eukaryotic cells came to be. DNA, RNA, Ribosomes and Protein Synthesis
</em>
<em>
</em>
<em>This provided the first substantial evidence for the endosymbiotic hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.</em>
<u>The carrying capacity of a population</u> does not affect the spatial distribution of a population
Explanation:
The carrying capacity only affects the number of individuals of a population that the habitat or environment can sustainably support, because it allows for the resources to replenish themselves.
Spatial distribution is how the individuals of the population are distributed across the habitat. They could be clustered, uniform or un-uniform. Distribution could be affected by;
- the distribution of food and other resources
- abiotic conditions like rainfall and sunlight
- the existence of predators or parasites
