Answer:
nucleicacid
Explanation:
DNA is made of chemical building blocks called nucleotides. ... To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating. The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C).
Weathering, erosion, and uplift occur at the same rates.
B.
Weathering, erosion, and uplift occur at the same rates now as they did in the past.
C.
Weathering, erosion, and uplift occur faster now than in the past.
D.
Weathering, erosion, and uplift occur slower now than in the past.
A. It does not rely on dependent variables, only independent variables.
•
B. It has more evidence than a hypothesis, but less than a law.
•
•
C. A hypothesis does not become a theory until it is already supported by evidence,
D. It is just a theory, it is equivalent to a guess.
Darwin's theory of Evolution by Natural Selection is not just a theory, because it can be testable. A hypothesis becomes a theory once it is supported by evidence (option C)
Charles Darwin described natural selection as an evolutionary phenomenon in which the fittest and strongest animal survives in nature, with the weakest animals dying first, greatly reducing the likelihood that they will have offspring. Therefore, the strongest are the ones that have offspring and pass on their most optimal traits so that these offspring are in turn more fit.
Each organism has different characteristics, and when organisms of a species reproduce, the progeny inherit these characteristics. Those members of the population with characteristics that are less adapted to the environment will be less likely to survive. And those with better characteristics are more likely to survive. For example, a gazelle that is slower to run because of some defect will be less likely to survive because it is likely to be chased and caught by a carnivorous animal. And this hunter is less likely to catch up with another gazelle that is stronger and faster to escape. In turn, this stronger gazelle, by surviving, will be more likely to reproduce and leave equally strong offspring.
Therefore, the classic definition of natural selection establishes that the conditions of the environment can hinder or favor the survival and reproduction of species and this determines that they evolve to adapt more and more. Therefore, evolution is the set of changes in a population, through generations. This process has originated the diversity of species from a common ancestor. For this to happen, traits must be variable between individuals and be related to survival and must be inheritable.
On the other hand, it should be clarified that a theory is a body of knowledge that explains a phenomenon based on observation or reasoning.
The right answer is:
Let's explain why the other items are incorrect:
So, Darwin's theory of Evolution by Natural Selection is the result of adaptations to the environment of organisms and can generate genetic mutations that lead to improvements in phenotypes and generate new species. And it is supported by scientific evidence by studying physiology, comparative anatomy between species, among other things.

Answer: C
Explanation: Darwin’s theory of evolution is based on Natural Selection. Natural Selection can be defined as the ability of an organism to evolve based on its suitability to the environment through genetic traits that are inherited by offspring.
Darwin’s Theory is not just a theory because it is testable, and can be used to make logical future predictions.
An example of this is the evolution of man.
The phenotype of the sons of the third generation depends on the dominant or the recessive traits of the parent.
A phenotype is an observable character that results from the interaction of the genotype with its environment. The phenotypes of the children of the third generation will show the result of the Stronger and more dominant gene and also may characteristics of the weak or the less dominant gene type.
For this, we need to study Mendel's laws were the parent that gene 2 and those of the grandparent that is gene 1 are crossed, and their characters are formed leading in the third gene.
Find out more information about the phenotype.
Answer:
The phenotype of children in the third generation depends on the dominant or recessive characteristics present in the alleles of grandparents and parents. To know the phenotypes you must understand Mendel's laws.Knowing the alleles of parents (generation II) and grandparents (generation I) through crosses, you can know what characteristics the children will have in the third generation.
A.independent assortment
B.incomplete dominace
C.segregation
D.codomiance
Answer:
I think you shud go for A.
Explanation:
Answer: I assume you meant biologist in this situation. A biologist is a type of scientist that studies living things, their environments, and how they live. Many different types of biologists exist, including research biologists, health care biologists, environmental biologists and biology educators. When it comes to research biologists they study different groups of living organisms around the world. Health care biologists are physicians, veterinarians, nurses and dentists. These types of biologists prevent spreading of infectious and deadly diseases and formulate ways to enhance the health of their patients. Biology educators teach students and up-and-coming biologists basic and sometimes advanced biological sciences in classroom, laboratory and field settings. Environmental biologists study ways to preserve the natural environments of different types of organisms. If you need an example they study animals in captivity and design new methods to help certain species live longer lives in their natural habitats.
Explanation: Hope this helps.
