What is evolution? How can evolution be scientific when no one was there to see it happen?
Answer:
Evolution is looking back and using scientific inference to make a timeline on adaptation of a species over time.
Explanation:
Looking at skulls, skeletal remains and carbon footprints left behind, we can compare and date remains of early humans and other species from years ago and compare them to late and modern remains. Thus making a timeline and showing the slow evolution of our adapting species.
Pls help, this is science class btw
Think about the meanings of the words "dependent" and "independent" as they relate two variables. What do you think "interdependence" means in terms of organisms that live together in an ecosystem?
Answer:
Explaination Down Below
Explanation:
Interdependance could mean how the two organisms are two different living things that work in different ways to eachother, yet because of the fact they live together in an ecosystem states the fact they work together to help that ecosystem thrive.

Explanation:
Using the sequence of DNA bases below, give the proper tRNA anticodons involved in protein synthesis.
TTAAGC
Answer:
AAUUCG is the mRNA's sequence and the codons are AAU and UCG. So the anticodons are complementary:
UUA and AGC
These are the anticodons
Note: Thymine is substituted with uracile in RNA

Explanation:
In 1980, a long dormant volcano, Mount St. Helens in Washington state, erupted violently. The eruption wiped out the forested landscape and the wildlife. Months after the initial disturbance, the ash and rock strewn surface began to undergo primary succession.
Answer:
New vegetation and animals came to this place when the environment is suitable.
Explanation:
The ash and rock strewn surface began to undergo primary succession after few month when the soil is cool down because the soil has nutritive medium that helps the vegetation to grow on that land. In the primary succession, the new vegetation grows which is well suited to that environmental condition and uses the nutrients present in that soil for its growth and development. Many new organisms also came to this new landscape when the environment is suitable.

Explanation:
What is the mass of a car that is going 2 m/s/s and then it hits a tree with a force for 6000 N?
Answer:
Mass = 2000kg
Explanation:
Mass = [tex]\frac{Force}{acceleration }[/tex]
= [tex]\frac{6000}{2}[/tex]
= 2000kg

The molecules of DNA are
__
so that each cell gets the same directions.
Answer:
Nucleotides
Explanation:
DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
which structure is found in the cytoplasm of a prokaryotic cell
Answer:
By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. Instead, the chromosome of a prokaryote is found in a part of the cytoplasm called a nucleoid. Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid.
Cladistics is a classification system based on
a. nomenclature
b. dichotomous keys
c. common ancestry
d. physical characteristics
Answer:
c
Explanation:
cladistics is based on evolutionary ancestry and generates trees called cladograms. Cladistics also identifies clades, which are groups of organisms that include an ancestor species and its descendants. Classifying organisms on the basis of descent from a common ancestor is called phylogenetic classification.

Describe the data used by Watson and Crick to determine the structure of DNA
they used Franklin's x-ray picture and data as well as other mathematical data to determine the specific structure of the DNA double helix. Compare and Contrast the structure of prokaryotic and eukaryotic chromosomes.
Data of X Ray diffraction is used by Watson and Crick to determine the structure of DNA.
What is X Ray diffraction?"X-ray diffraction is a phenomenon in which the atoms of a crystal, by virtue of their uniform spacing, cause an interference pattern of the waves present in an incident beam of X rays."This is used for determining the 3D structures of crystal.By using data of this method Watson and Crick gives helical structure of DNA.
Hence, the data used is of X Ray diffraction.

The statement-One support of the behavioral perspective is that it is backed by strong and extensive research is True.
What is behavioral perspective?The behavioral perspective is a psychological approach that focuses on observable behavior, rather than internal mental processes, as the key to understanding and predicting human behavior.
The behavioral perspective in psychology is based on the belief that behaviors are learned through the environment. This perspective has been extensively researched in the laboratory and in real-world settings, and the findings of this research have been consistently replicated over time.
Overall, the behavioral perspective is backed by a wealth of empirical evidence and has a strong track record of producing practical applications in both research and clinical settings. Therefore, the given statement is True.
