How can you determine if 2 organisms are in the same species?
If two organisms are able to mate and produce fertile offspring, then they are of the same species.Horses and donkeys are two different species because if they mate, they produce a mule which is sterile (not fertile). This shows horses and donkeys are of different species.
How does a biologist determine whether a thing is living or nonliving?
Biologists determine whether a thing is living or nonliving by a list of characteristics. These characteristics include the ability to reproduce, the ability to eat, the ability to grow and the ability to excrete waste.
2 Scientists can tell whether organisms are closely related by comparing their?
2.Scientists can tell whether organisms are closely related by comparing their ____.(1 point)DNA, I had this on my test too and I answered DNA and got it right.
Can two organisms have the same genotype?
Yes.If* two or more organisms are formed from the same original cell, and* all divisions of that cell are by mitosis, and * there is no mutation, then the organisms will be genetically identical (= have the same genotype).Some examples:* human identical (monozygotic) twins * individuals of Hydra, a freshwater coelenterate, formed by budding * plants formed by vegetative propagation, such as budding (e.g. fruit trees in horticulture) and forming stolons (e.g. strawberries naturally)
Name two factors that will determine whether a non-native species becomes an invasive species?
1.Very high and still Increasing population and 2. They are dominating or killing off other species in the area
What characteristic determines whether organisms belong to the same species?
The number of chromosomes. For example, humans have 46.
What do biologists use to classify animal's?
Biology may use skeletal similarities in determining where extinct animals are placed in relation to surviving species and other extinct species. Chromosomal similarities, whether they are eukaryotes (animals, plants, fungi), or whether they are prokaryotes (bacteria, archaea) are commonly used to classify modern species. Species that are believed to have a similar ancestor are grouped into genuses.
What determines whether a species is known or unknown?
A species is a group of closely related organisms. Organisms belong to the same species if they can mate and produce fertile offspring. A lion and tiger are not the same species because they can make a liger, but it will not be fertile.
Which classification level includes organisms that are most closely related to one another?
They are the related because the levels of classification start with Kingdom which is the biggest and end with species which is the smallest. The evolutionary relationships start with many animals or humans and works its way down to one animal or human.
What are the facts about species?
Your question is actually far more difficult to answer than it first appears. The definition of a species, at least to many biologists, is a group of organisms that cannot reproduce with any other group to produce viable offspring. Clearly, an oak tree and humans are different species. However its difficult to say whether some officially distinct species can or cannot reproduce. Humans can't reproduce with oak trees for purely mechanical reasons - our sperm won't fertilize their "eggs", or vice versa. And in the wild (most of the time), lions simply will not mate with tigers, but in a zoo they will, producing a liger. So are they different species in the wild but not in captivity?

What does the owner consider when deciding whether to establish an account with a sales representative?

Do tigers have bits of human DNA?
DNA contains instructions inside the cell that establish whether an animal will be a tiger or a human. All living things with cells have DNA which are specific to their species.
What are two main characteristics biologists look for when classifing animals?
One of the main ones are whether they are vertebrates orinvertebrates. vertebrates have a spinal column, invertebrates do not. 95% of all animal species do not. I'm not sure what the second one would be.the second one is whether they nurse their youngchordata and mammalia are the two great dividers
What do microbiologists do?
The Microbiologist are the ones that study about microbic organisms or the organisms having the size of 10^-6 m. They are not visible by naked eyes. They are grown on culture medium for carrying out studies and extracting the useful enzymes from them.
Is being a gay something you're born with or something you used to?
Homosexuality is very prevalent in nature, with biologists having observed over 3000 species that exhibit such behaviour. In other words, there is a natural explanation for homosexuality. Some biologists speculate that it is a form of birth control that prevents the overpopulation of a particular species and can therefore be attributed to genetics and ultimately as an evolutionary process.So to answer the question:While it is true that homosexuality is sometimes caused by environment, upbringing, etc, you cannot be sure whether it is because of conditioning or genetics that someone is gay.
