Body’s of water i think
Dead zones occur because of a process called eutrophication, which happens when a body of water gets too many nutrients, such as phosphorus and nitrogen. ... Human activities are the main cause of these excess nutrients being washed into the ocean.
A marmoset is a member of the family of primates and are known to be one of the smallest monkey. They are measured to have a body length of 12 - 15 inches and has a mass of approximately 100 - 125 g. Comparing to monkeys, marmosets have distinct characteristics. Instead of having nails, they have claws, they tactile hair or a sensitive hair found on their wrists. They do not have wisdom teeth and the layout of their brain is primitive.
Natural selection is basically when organisms with the best traits survive and pass on their good traits to their offspring so that they will adapt easily and survive. Organisms who do not have ‘good traits’ that help them adapt and escape predators will be killed or eaten before they reproduce.
So in the end, natural selection is a form of evolution that allows the ‘fittest’ animals to survive and reproduce, while weeding out the unfit.
Answer:
4.
Explanation:
Synteny oe syntenic gene is defined as the physical co-localization of genetic loci on the same chromosome within a speciesand inidvidual.
In the beginning of the meiosis process, when genes are present in the same chromosomes but very far, they undergo indepedent assort due to homologous recombination and the random exchnage of matching fragment in homologous chromosomes takes place. During the crossing over there are very less chances that all types of gametes are produced accurate frequency.
Hence, the correct answer is 4.
