in the ribosome. Find and drag its match, the UAC anticodon, to it. Also, record this pair and the
associated amino acid, Met, to complete the first row of the data table.
Answers
The first codon in the ribosome is AUG, which codes for the amino acid methionine (Met). The anticodon for methionine is UAC. So, drag the UAC anticodon to the ribosome next to the AUG codon.
How to obtain codons?Also record this pair and the associated amino acid, Met, in the data table. The data table would look like this:
Codon Anticodon Amino Acid
AUG UAC Met
Then continue to find the correct tRNA anticodons for the remaining codons in the mRNA molecule. The table would be complete when all of the codons have been paired with their corresponding anticodons and amino acids.

The seed formed inside the ovary of the flower. As the seed develops in the flower, water is withdrawn from it so that it becomes almost dry. suggest why is it important?
Answers
Water withdrawal from the developing seed inside the flower is important to induce dormancy, enhance longevity, protect against pathogens, facilitate dispersal, and trigger germination under favorable conditions.
Water withdrawal from the seed during its development inside the ovary is crucial for seed dormancy, longevity, protection, dispersal, and germination. Dormancy enables seeds to survive unfavorable conditions. The dry state reduces metabolic activity, enhancing seed longevity. Withdrawing water creates an inhospitable environment for pathogens, safeguarding the seed. Dry seeds are lighter and more easily dispersed by wind, animals, or water, aiding in the colonization of new habitats. Rehydration of the seed after dispersal triggers germination, initiating growth.Overall, water withdrawal from the seed inside the ovary serves as a survival strategy, allowing seeds to endure harsh conditions, remain viable for extended periods, avoid microbial damage, disperse effectively, and germinate when conditions are favorable.

Scenario: In a population of spiders living on Arachnid Island, most of the spiders are gray; a few are brown. On nearby Spider Island, there is another population of the same species. There, most of the spiders are brown; a few are gray. The ocean between these islands is full of hungry fish, and the spiders don't swim, so there is very little movement of spiders between the islands.Initial makeup of each population:Arachnid Island: 90% gray, 10% brown Spider Island: 10% gray, 90% brownThen a bridge is built to connect the islands so that tourists can ride their bikes from one to the other. The bridge is also a nice environment for spiders, so they start to move back and forth between the islands.How do you predict the makeup of the populations will be changed if this movement continues for many generations? Answer the questions below to identify and describe this change in the population.1. Is this an example of mutation, selection, genetic drift, or gene flow?

Due to the building of the bridge, now both spiders population are communicated and are able to cross, this will lead to the allele frecuency to vary, which is an example of genetic drift.
What are the four types of final impression material? Of the four, which one is the seems to be the least desirable to use, based on what you have read about each of the four types.
Answers
The four types of final impression materials are: 1) inelastic impression materials, 2) elastomeric impression materials, 3) hydrocolloid impression materials, and 4) inorganic impression materials.
Inelastic impression materials, which include plaster and compound materials, seem to be the least desirable to use as final impression materials. These materials are rigid and lack flexibility, which makes it difficult to obtain accurate impressions of complex oral structures, and they can also cause discomfort for patients during the impression process.
Elastomeric impression materials, hydrocolloid impression materials, and inorganic impression materials have largely replaced inelastic materials due to their improved accuracy and ease of use.

Compare and contrast a fossil with a trace fossil
Answers
Definition:
- Fossil: A fossil refers to the preserved remains or traces of organisms that lived in the past. It can include the hard parts of plants or animals, such as bones, shells, teeth, or wood.
- Trace Fossil: A trace fossil, also known as an ichnofossil, refers to indirect evidence of prehistoric life activities, such as footprints, burrows, tracks, trails, or even feces (coprolites).
Formation:
- Fossil: Fossils form when the remains or hard parts of organisms are buried in sediment or other materials, undergo mineralization over time, and become preserved.
- Trace Fossil: Trace fossils form when an organism's activity or behavior, rather than the organism itself, creates an impression or trace that is preserved in the geological record.
Information Provided:
- Fossil: Fossils can provide direct information about the physical characteristics, anatomy, and structure of ancient organisms. They can offer insights into their evolutionary relationships, adaptations, and paleoenvironments.
- Trace Fossil: Trace fossils provide indirect information about the behavior, locomotion, feeding habits, and ecological interactions of ancient organisms. They can reveal details about their movement patterns, burrowing behavior, or group activities.
Preservation:
- Fossil: Fossils typically require specific conditions for preservation, such as rapid burial, anoxic environments, or mineral-rich sediment. They are often preserved in sedimentary rocks, amber, or ice.
- Trace Fossil: Trace fossils can form in various types of sediments, including mud, sand, or volcanic ash. They can also occur in hardened substrates like limestone or volcanic rock.
Types and Examples:
- Fossil: Examples of fossils include bones, teeth, shells, petrified wood, and preserved soft tissues like feathers or leaves.
- Trace Fossil: Examples of trace fossils include footprints, tracks, burrows, nests, feeding traces, or coprolites (fossilized feces).
In summary, a fossil refers to the preserved remains or traces of organisms themselves, providing direct information about their physical characteristics. On the other hand, a trace fossil refers to indirect evidence of prehistoric life activities, offering insights into behaviors, locomotion, and ecological interactions. Both types of fossils contribute to our understanding of ancient life forms and ecosystems, but through different perspectives and types of evidence.

Answers
Answer:
A. Selective pressure in the form of a new predator
Explanation:
A. Selective pressure in the form of a new predator
A. Selective pressure in the form of a new predator is the most likely factor that caused the noncroaking male population to increase after 2004.
What is noncroaking males?Noncroaking males refer to male bullfrogs that do not produce croaking sounds as a form of communication or mating behavior.
The migration of a bat species that preyed on male frogs likely created a selective pressure on the population, favoring those males that did not croak and thereby avoiding detection by the predator. This would result in a higher proportion of noncroaking males in the population over time as they have a higher likelihood of survival and reproduction.
The increase in the noncroaking male population after the arrival of the bat predator in 2005 could be due to adaptation of the male frogs to the new selective pressure in the form of the predator.
It is possible that the noncroaking males were able to avoid detection by the bat predator better than the croaking males, leading to a higher survival rate and ultimately a higher population.
Additionally, it is possible that the croaking males were more likely to be predated upon, leading to a decrease in their population and an increase in the noncroaking male population.
However, it is also possible that other factors, such as changes in the environment or competition with other species, could have contributed to the observed changes in the bullfrog population over time.

Since they have a greater metabolism, smaller creatures breathe more quickly.
What is Oxygen consumption of an Experiment?1. In general, the rate of oxygen consumption increases with the increase of temperature. So, here at 30 degree the rate of consumption will be the highest, then at 15 degree, at zero degree it will be ice droplets.
2. The aerobic bacteria present in the water respire in the presence of oxygen. at 0,15 and 30 degree. Here anerobic bacteria can be taken as a control.
So, a culture with medium of aerobic bacteria/yeast can be taken.
It is kept in shaking condition 150-200 rpm and then the temperature is kept at 37 degree.
Bacteria has a doubling time of twenty mins, and yeast has a doubling time of 90mins. So, it is kept at overnight incubation for proper growth of the bacteria. Water droplets are visible at the cap.
At 30 degree the consumption is maximum, then the 15 degree is relatively lower and higher is no consumption at 0 degree where it is frozen.

Check all that are true
A- outer part (outside of cell)
B- center of cell membrane
C- membrane layer facing into the cell
Answers
Answer:
B
Explanation:
The cell membrane is made up of a "lipid bilayer" This means that there is are two lipid molecules, each of which has a hydrophilic(water loving) head and hydrophobic(water hating) tail. In the membrane there are 2 molecules facing away from each other such that the head of the lipid faces out and the tail is on the inside. Therefore, with the hydrophobic tail on the inside or center of the membrane it would repel water.
The outer part and the center of the cell membrane are both hydrophobic, which means they repel water.
The cell membrane is a lipid bilayer, which means it is made up of two layers of phospholipids. Phospholipids are molecules that have a hydrophilic head and a hydrophobic tail. The hydrophilic head is attracted to water, while the hydrophobic tail is repelled by water.
The outer part of the cell membrane is exposed to the extracellular fluid, which is mostly water. The hydrophobic tails of the phospholipids in the outer part of the cell membrane are repelled by the water, which helps to keep the membrane from dissolving in the extracellular fluid.
The center of the cell membrane is also hydrophobic because it is made up of the hydrophobic tails of the phospholipids. The hydrophobic tails of the phospholipids in the center of the cell membrane are repelled by each other, which helps to keep the membrane from collapsing.
The membrane layer facing into the cell is also made up of phospholipids, but the hydrophilic heads of the phospholipids in this layer are facing inward, towards the cytoplasm of the cell. The hydrophilic heads of the phospholipids are attracted to the water in the cytoplasm, which helps to keep the membrane from dissolving in the cytoplasm.
