How is a clade differentiated from another clade
Answers
Answer:
A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.
Explanation:
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.
Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades
Answer:
A clade is a monophyletic grouping in which all the organisms stem from the same branching point.
Explanation:
The organisms in a clade must all stem from the same branching point in evolutionary history, as represented in the phylogenetic tree.

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.
Answers
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.

Answers
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).

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.
Answers
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.

What effect will the settling of sediment have on the shape of the stream?
Answers
The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
Answer:
Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?
Answer:
The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

Describe how heat moves in a convection current. How is this process responsible for moving earth’s tectonic plates?
Answers
Part 2: The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.
Explanation:
Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

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.

Which of the following is an example of aerobic respiration? A.Lactic acid fermentation in human muscles B.Physical exchange of gases in human lungs C.Respiration during vigorous physical exercise D.Breaking down of glucose with oxygen inside an animal cell
Answers
D. Breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.
Lactic acid fermentation occurs in human muscles and it is not a type of aerobic respiration as it occurs in the absence of oxygen gas. In this process, lactate or lactic acid is produced by the glucose. Physical exchange of gases in human lungs is called breathing. Respiration during vigorous physical exercise is an example of anaerobic respiration because vigorous physical exercise creates deficiency of oxygen. Aerobic respiration is a type of cellular respiration in which the glucose is broken down to release energy in the form of ATP or adenosine triphosphate in the presence of oxygen. This type of respiration occurs in both animal and plant cells. Hence, breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.Learn more about aerobic respiration:
