Explanation:
You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes
Answer:
C. Phenotypes
Explanation:
Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.
Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.
So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.
Hence, the correct option is "C. phenotypes".

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Answer:
The options to this question are:
A) allele
B) codon
C) nucleotide
D) chromosome
The answer is A) allele
Explanation:
RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.
However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).

Consider the image of our solar system. Based on your knowledge of gravitational attraction, which planet has the largest gravitational force? A) Earth B) Jupiter C) Mercury D) Neptune
Answer:
Jupiter
Explanation:
Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.
With a radius of 43,440.7 miles (69,911 kilometers), Jupiter is 11 times wider than Earth. If Earth were the size of a nickel, Jupiter would be about as big as a basketball.
From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes Sunlight 43 minutes to travel from the Sun to Jupiter.

Explanation:lo que dice ahi neta que si
Answer:
Taxonomy
Explanation:
Prior to being able to sequence DNA, organisms were described and categorized solely by their distinct morphologies (physical characteristics) and ecological roles. The ability to sequence DNA has revealed a great deal more about where an organism belongs taxonomically and helps pinpoint new species. DNA is now used alongside morphology and ecology to substantiate an organism’s distinctiveness in the biological world.

A terrarium is a small, enclosed ecosystem. If you change certain aspects of the terrarium, the climate that exists inside it will also change. Examine the image of a terrarium. Then identify one attribute of the terrarium that you could change to alter the climate inside. How would this change mimic the climate changes that we see on Earth?
Answer: Putting a lid on the terrarium will increase the humidity.
Explanation:
Putting a lid on the terrarium will increase the humidity.
What is Humidity?Humidity is a measurement of the air's water vapor content. If there is a lot of water vapor in the air, the humidity will be high. As the humidity increases, it feels more humid outside.
In weather reports, humidity is frequently described using the word "relative humidity." The percentage of the maximum quantity of water vapor that the air can hold at a given temperature that is actually present in the air is referred to as relative humidity.
A chilling -10 degrees Celsius in the air (14 degrees Fahrenheit). At this temperature, the air can only hold 2.2 grams of water per cubic meter.
Therefore, Putting a lid on the terrarium will increase the humidity.

A. coprolite
B. trace
C. record
D. index
Answer:
ttrace
Explanation:
A trace fossil is evidence of an organism, but is not made of the organism itself.
What is Trace fossil?The structure and behaviors of an organism, rather than its physical form, are used to classify trace fossils. A few of the trace fossils discovered in Denali have been connected to body fossils discovered in rocks from the North Slope or Talkeetna Mountains that are of a comparable age.
These connections provide investigators access to identities that are more certain than those known solely from trace fossils.
Bird tracks near probe marks in the earth suggest that the birds were using their beaks to dig for food. Invertebrate burrows located in the same rocks possibly provide the answer to what good food the birds were eating.
Therefore, A trace fossil is evidence of an organism, but is not made of the organism itself.

What did the Tennessee court decide in the Scopes trial?
A. Scopes broke the law by teaching evolution.
O B. Humans evolved from monkeys.
C. Humans didn't evolve from monkeys
D. It was unconstitutional to teach evolution.
The Tennessee court decided in the Scopes trial that scopes broke the law by teaching evolution. Therefore, option (A) is correct.
The Tennessee court found that John T. Scopes violated the Butler Act by teaching evolution in a state-funded school. The Butler Act banned human evolution in Tennessee schools. High school teacher Scopes purposefully taught evolution to dispute the law's constitutionality and promote academic freedom.
Scopes was convicted and fined in 1925. The trial symbolised the US conflict between contemporary science and old religion.
The Butler Act was upheld and Scopes found guilty, but the case ignited debate on evolution in education and church-state separation. It led to landmark judgements on academic freedom and constitutional rights in education and legal disputes over teaching evolution in public schools. Therefore, option (A) is correct.

How could the notion of maximum parsimony lead to an error in establishing an evolutionary relationship
Answer:
The notion of maximum parsimony does not consider the entire evolutionary history, being able to suppress important evolutionary points that would cause errors in the evolutionary relationship of a species.
Explanation:
Maximum parsimony is a criterion for optimizing phylogenetic trees. This is because through this criterion an analysis is made of all possible phylogenetic trees of a species, observing which one is smaller and offers simpler and summary information. On the one hand, the study of the smallest phylogenetic tree can be faster and more understandable, since its information is basic and direct. However, maximum parsimony can lead to errors in the establishment of an evolutionary relationship of a species, because it suppresses the entire history of evolution of that species, being able to suppress really important points in one of the clades, which would result in an incorrect evolutionary conclusion.

Sometimes, distinguishing the type of interaction between species in not straightforward. Remoras are fish that are often found attached to larger animals, such as sharks. The relationship between remoras and sharks is often described as a commensalism. Although this suggests that sharks do not benefit from this relationship, remoras sometimes consume parasites on their skin. Which of the statements below best supports the relationship being a commensalism?
Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Although remoras consume parasites, they usually consume the flesh of the shark itself and harm it.
Remoras consume parasites, but sharks depend on parasites to remain healthy.
The fact that remoras consume parasites suggests that they provide a benefit, making this a commensal relationship.
Answer:
The commensal relationship between the sharks and remoras can be described as although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Explanation:
A commensal relationship refers to a relationship where two or more organisms in a habitat neither benefit or harm each other.
The second option infers that the remoras harm the sharks. This is a parasitic relationship.The third option infers that the sharks are harmed by the remoras because the sharks depend on something that the remoras are limiting. This is also a parasitic relationship.The fourth option infers a commensal relationship, but falsely describes it. The relationship described by this option is a parasitic relationship (one benefits, the other does not).Therefore, the answer is the first option: Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Answer:
it is A) Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
