Having homologous chromosomes indicates that the organism is a DIPLOID SPECIE.
A homologous chromosome refers to a pair of chromosomes which originate from each parent. Homologous chromosomes posses the same length, banding patterns, amount of genes, location of genes and location of centromeres. However the genes in the homologous chromosomes may or may not be the same.
Answer:
embryos (the organisms early stage foetal development )
A constant is something that is kept the same throughout the course of a experiment. So I would guess C) because they are not doing anything special. If it’s not C then it is A. :)
Answer:
This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.
tree and nest
If a robin builds a nest in a big tree, the robin benefits and the tree
is not helped or harmed. This type of symbiotic relationship is called
commensalism, and it is between the tree and the nest/Robin.
<span>There are several types of biotic relationships that is occurring every single moment in the ecosystem and commensalism is one. In contrast, parasitism is the biotic relationship where one organism doesn't benefit from the other and is harmed. In this scenario with human beings and mosquitos, this phenomenon of interaction is distinguished as parasitism where mosquitos draws blood that contains nutrients from the human tissue to use it as its source of food and then leaves harmful substances and bacteria in the human’s blood stream.<span> </span></span>
