Which characteristics of a population would most likely indicate the lowest potential for evolutionary change in that population? Variation within the species.
Which processes result directly in the formation of cells?
Answer Expert Verified. The process described here is meiosis. Meiosis has two general stages, meiosis I and meiosis II and at the end of these stages, the sex cells or gametes of an organism are formed.
Where is most of the hereditary information that?
Hereditary information is contained in genes, located in the chromosomes of each cell. Each gene carries a single unit of information. An inherited trait of an individual can be determined by one or many genes, and a single gene can influence more than one trait. A human cell contains many thousands of different genes.
What would most likely occur after an ecosystem is disrupted by fire?
What would most likely occur after an ecosystem is disrupted by fire? The ecosystem would eventually return to its original state.
Which process is least likely to add to the variety of traits in a population?
Deletion bases would also lead to alteration in DNA and exchange of segments between chromosomes is known as crossover which is essential for variety of traits. Accurate replication would produce the same traits in a population so it is least likely to add variety of traits.
Which farming practice causes the least harm to the environment?
Answer Expert Verified. Using Natural predators to reduce insect numbers caused the least harm to the environment.
Which of the following statements concerning production of offspring is correct?
Therefore, the correct statement is “production of offspring is necessary for a species to survive, but it is not necessary for an individual to survive”.
Which process helps reduce global warming?
Global warming is a natural phenomena which is caused due to increase in abundance of greenhouse gases into the atmosphere. The process of photosynthesis will reduce the amount of carbon dioxide present in the atmosphere as carbon dioxide gas will be absorbed by the plants so as to produce their food.
Which structure determines the traits that will be passed to offspring?
Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.
What are the four chemicals in DNA?
DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
Which is the most important cause of habitat destruction?
Other important causes of habitat destruction include mining, logging, trawling, and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide. It is a process of natural environmental change that may be caused by habitat fragmentation, geological processes,…
How is habitat loss related to biodiversity loss?
Habitat Destruction. Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. It often results in the extinction of species and, as a result, the loss of biodiversity .
Which is the most important factor in species extinction?
The destruction and fragmentation are the 2 most important factors in species extinction. The negative effects of decreasing size and increasing of isolation of habitat are misinterpreted by fragmentation, but in reality they are much more larger effects on the population.
Is the loss of habitat the greatest threat to wildlife?
Habitat destruction is not the only threat facing wildlife, but it is quite likely the greatest. Today, it is taking place at such a rate that species are beginning to disappear in extraordinary numbers.
