Answer:
these are odd questions....
Explanation:
1. they are curious about how they get blind
2. the quills
Answer:
1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."
2. Another effect it might have is to improve cave tetras' sense of smell.

Water that reaches the ground and moves horizontally towards rivers, streams, and lakes is called runoff.
A. True
B. False
Answer:
A. True
Explanation:
flow off a hill slope directly to a stream in the form of runoff, or it may flows downward through the unsaturated zone to reach the water table. The area at the stream or lake to which the groundwater is flowing. Recall that water is flowing in pores where there is friction, which means it takes work to move the water.
Why are molecular clocks important in the construction of cladograms? They compare the frequency of reproduction to determine which traits evolved through mutations. They compare the genes inherited by a species to determine descendants. They compare the number of mutations to determine how long ago species separated and evolved.
Answer: They compare the number of mutations to determine how long ago species separated and evolved.

True
Explanation:
An individual who exhibits a mixture of schizophrenic symptoms most likely has undifferentiated schizophrenia.
The most likely diagnosis for someone who displays a variety of schizophrenic symptoms is undifferentiated schizophrenia. The aforementioned is therefore True.
What is schizophrenia?The illness that impairs a person's capacity for clear thinking, feeling, and behaviour is schizophrenia. Although the precise origin of schizophrenia is unknown, it is thought that a mix of genetics, environment, and changes in brain chemistry and organization may be at play.
Schizophrenia is characterized as disorganised speech or behaviour, depressed participation in daily tasks, and ideas or experiences that appear disconnected from reality. Memory loss and attention problems could also be present.
Therapy is typically ongoing and frequently consists of a mix of prescription drugs, psychotherapy, and well-coordinated specialty care services.
So, the given statement is True.

Which of the following statements about coral reefs is TRUE?
O Coral reefs are generally less than ten years old.
o Coral reefs contain a great diversity of life and species.
O Coral reefs cover most of the world's ocean floor.
O Coral reefs contain very few species other than fish.
Answer:
The correct answer is "Coral reefs contain a great diversity of life and species." as while they cover 1% of the ocean floor, they are homes to more than 25% of marine life.
Explanation:
The following statements about coral reefs are true: "Coral reefs contain a great diversity of life and species." That is the second option, as the coral reefs are among the most diverse and biologically rich ecosystems on the planet.
What is the importance of coral reefs to the ecosystem?The coral reef is a type of structure that forms large, interconnected structures, creating a habitat for a wide range of other species, such as fish, crustaceans, and mollusks, and the reef provides shelter and food for a diverse array of organisms. Coral reefs generally occur in warm waters along the coasts of tropical and subtropical areas, so climate change harms them.
Hence, the following statements about coral reefs are true: "Coral reefs contain a great diversity of life and species." That is the second option, as the coral reefs are among the most diverse and biologically rich ecosystems on the planet.

In regards to the Central Dogma... Select one: a. Transcription involves RNA polymerase which is recruited to origins of replication by transcription factors b. Eukaryotic mature messenger RNA, exported from the nucleus to cytoplasm, has been spliced and modified at the 5' and 3' end. c. The 5' cap is a modified cytosine nucleotide and the 3' polyA tail is comprised of 50-250 alanine residues. The purpose is to stabilize the mRNA. d. The mature messenger RNA is translated by the ribosome in the cytoplasm. The ribosome reads the mRNA in a 5' -->3' direction while synthesizing protein in a N-->C direction e. multiple of the options are true
Answer:e. multiple of the options are true
Explanation:
DNA central dogman involves DNA replication, DNA transcription and DNA translation which involves the formation of protein.
Replicated DNA are transcribed to an intermediary mRNA(Messenger ribonucleic acid) from where it is moved from the nucleus to ribosome in the cytoplasm. Enzyme RNA polymerase helps in proof reading ,replication and transcription of bases during transcription. translation takes place in the ribosome with the help of ribosome in the presence of enzyme tRNA (transferase ribonucleic acid) that reads the codon and brings corresponding amino acid which are functional protein.
Explain why ecologists think the focus of conservation efforts should be ecosystems, not individual species?
It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.

If some bacteria are resistant to tetracycline and some are not resistant, what happens when a patient is given tetracycline for an infection?
Answer:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

a. Draw a food chain that could exist in your ecosystem.
b. Draw a large arrow to show how the energy flows through your food chain
Answer:
Explanation:
This is an example
A. The following food chain in a simple terrestrial ecosystem:
Grass → Grasshopper → Frog → Snake → Hawk
B. The energy flow will be directed as follows:
grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)
Food Chain:
Consider the following food chain in a simple terrestrial ecosystem:
Grass → Grasshopper → Frog → Snake → Hawk
In this food chain, the grasshopper is the major producer, the frog is the secondary consumer, the snake is the tertiary consumer, and the hawk is the quaternary consumer.
B. Flow of Energy:
The giant arrow representing the flow of energy through the food chain would start with grasses and progress through each trophic level. Energy moves along the food chain in a way that passes from one organism to another when it is consumed.
The energy flow will be directed as follows:
grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)
The arrows indicate that the sun's energy is taken up by the grass through photosynthesis and then transferred to each successive level when the organism consumes it.
