One of the four nucleotide bases in DNA is replaced by a different base in RNA. Which base is it, and what is it replaced by?a. transcription and then translation
b. thymine, replaced by uracil.
c. both a and c are correct
d. hydrogen bond.
Answers
One of the four nucleotide bases in DNA will be replaced by a different base in RNA. The base is thymine and it is replaced by uracil in RNA. Option B is correct.
DNA and RNA are nucleic acids that are composed of nucleotide subunits, each consisting of a sugar, a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T), while RNA uses uracil (U) instead of thymine.
During transcription, the process by which RNA is synthesized from a DNA template, RNA polymerase reads the DNA sequence and incorporates complementary RNA nucleotides, creating a single-stranded RNA molecule that is complementary to the DNA template.
In RNA, uracil (U) pairs with adenine (A) via hydrogen bonds, while in DNA, thymine (T) pairs with adenine (A) via hydrogen bonds. Therefore, during transcription, thymine is replaced by uracil in RNA, which allows for base-pairing with adenine and ultimately the production of the RNA molecule.

Their noses are pointing down and their holes are close to each other. They have semi-thumb or no thumb at all. They have plane nails.They have big brains and skulls. They spend most of their time on the ground, resting on rocks or similar places too height. However, they can also be found in trees.New-World Monkeys:
They are small-sized animalsTheir brain and skulls are small.Their nose holes are separated from each other and pointing at each side. Their thumb is developed because they have arboreal habits, so they need the thumbs to hold to the branches and move. They spend most of their time on trees. They hardly move on the floor.

write an essay on ectoparasites
Example of ectoparasites
Answers
Answer:
Ectoparasites are organisms that live on the skin of a host, from which they derive their sustenance. The phylum Arthropoda includes the two-winged, or dipterous, flies. The larvae or maggots of these flies may invade the living or necrotic tissue of animals and humans, producing myiasis. Multiple dipterous flies are thought to be capable of producing ocular myiasis. It is thought that the larvae are embedded in the eye, that they burrow directly through the sclera and then under the retina. Typically, they leave asymptomatic tracks throughout the fundus, but a number of cases of destructive endophthalmitis have been reported, particularly from Scandinavia.

In the box it says from left to right Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.
Answers
"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."
SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.
Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

the organisms that feed on dead and decaying matter are called
A. Saprotrophs
B. Autotrophs
C. Heterotrophs
D. Parasite
Answers
The organisms that feed on dead and decaying matter are called Saprotrophs.
An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms
Answer:
A. Saprotrophs
Explanation:
Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.
These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.
Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.
Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.
Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Instead of simply following instructions, students formulate research questions, develop hypotheses, plan and execute experiments, collect and analyze data, and draw conclusions. For instance, students may investigate the effect of different variables on plant growth by manipulating factors like light, water, or soil composition. This approach allows students to engage in authentic scientific practices, develop problem-solving skills, and gain a deeper understanding of the scientific method. By actively participating in their learning process, students develop a sense of ownership and become more engaged, fostering a love for learning and nurturing their ability to explore and discover knowledge independently.For more such questions on Pedagogy:

Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others,
they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at
locating and capturing prey.
Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting
behavior of bats be affected by such an environment?
A
Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
B.

Answers
Answer:
A
Simply the noise from heavy traffic will cause the destructive interference which reduces the echolocation,blocking the echoes and therefore prevent prey location for bats.
Generally this reduces the Bats' population, as some could not rely on the echo to locate the prey, leading to starving and death. Thus each bat needs to rely on the individual echolocation from the prey to survive as new hunting adaptation.Since the echolocations has been blocked
