What else can I help you with?
In any ecosystem the basic resources that organisms need for survival are always in limited supply. is a potential result of these limitations?
Competition among organisms for limited resources can arise, leading to natural selection and the development of adaptations that improve an organism's ability to access those resources. This competition can also drive species to occupy different niches within the ecosystem to reduce direct competition.
Why do diploids always contain an even number of chromosomes?
Diploids have two sets of chromosomes, one inherited from each parent. Each set consists of homologous pairs, one from the mother and one from the father. Therefore, diploids always have an even number of chromosomes to ensure that each homologous pair can align properly during cell division.
Why arent chromosomes always visible?
Chromosomes are not always visible because they are usually tightly packed and condensed into a structure called chromatin during most phases of the cell cycle. It is only during cell division when chromosomes become highly condensed and visible under a microscope.
What is is the difference between interspecific competition and intraspecific competition?
Interspecific : Interspecific competition, in ecology, is a form of competition in which individuals of different species vie for the same resource in an ecosystem (e.g. food or living space). The other form of competition is intraspecific competition, which involves organisms of the same species.Intraspecific : Intraspecific competition is a particular form of competition in which members of the same species vie for the same resource in an ecosystem (e.g. food, light, nutrients, space). This can be contrasted with Interspecific competition, in which different species compete.Source(s):Google Definitions
How many chromosomes are in the bodycells or an organism that has a haploid number of 8?
The diploid number of chromosomes for an organism with a haploid number of 8 would be 16. This means that in the body cells of this organism, there would be 16 chromosomes, with each chromosome having a pair (homologous chromosomes).
Do more-complex organisms always have more chromosomes than simpler organisms do.?
Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
Are organisms that look alike always part of the same species?
no they can be but aren't always from the same species
Do more complex organisms always have more chromosomes than simpler organisims?
No
Why is the chromosome number in organisms always even?
Chromosomes come in pairs, so the number is even.
Are organisms always beneficial?
No, organisms are not always beneficial. Some organisms can be harmful or have neutral effects on their environment and other species. It depends on the specific interactions and relationships between organisms in their ecosystem.
How many chromosomes do protists have?
Protists can have a wide range of chromosome numbers, which can vary from species to species. They may have a haploid number (n) or a diploid number (2n) or other variations, depending on the specific protist.
Do more complex organisms always have more chromosomes than than simpler organisms do?
More complex eukaryotes do not necessarily have more chromosomes than simpler eukaryotes do. An example from the Holt Science book is that fruit flies have 8 chromosomes, potatoes have 48, and humans have 46. The human cells are more complex, but they don't have quite as many chromosomes as potatoes!
Are organisms in the same genus are not necessarily members of the same family?
Two organisms belonging to the same genus always belong to the same family.
Is there any other species with 46 chromosomes?
Black rat, and like 8 others but black rats don't always have 46.
Using genus and species how can you tell if organisms are similar?
To tell if organisms are similar you need to use the genus, species name always changes. For example: wolves and domestic dogs. A wolf's scientific name is canis lupus. A dog's scientific name is canis familiaris. All animals in the dog family start with canis, then from there there species name, and then from there, there is the sub-species name.
Is the taxonomic classification of all organisms certain?
Taxonomic classification is not always certain due to ongoing research and new discoveries. As our understanding of species and their relationships evolves, classification systems may change. Additionally, different taxonomists may have varying opinions on how organisms should be classified.
