How is the temperature of a liquid substance affected when it is boiling?
OA) It increases.
OB) It decreases.
OC) It stays the same.
Answer: It increases
Explanation: A liquid boils at a higher temperature. When heat is applied to the liquid, the temperature increases until it reaches its boiling temperature (boiling point), a temperature at which it starts to boil. For instance pure water boils at 100°C and freezes at 0°C. As the liquid continues to boil, the temperature continues to increase.
Explain how scientists would classify an extinct species such as a dinosaur. In your answer , discuss some of the difficulties that he or she may face
Answer:
To classify an extinct species, the scientist might have to look for any kinds of clues he can look for in the fossil record. The scientist might look for the evolutionary traits and predict that the dinosaur has closest resemblance to which other types of dinosaurs. In this way, he can place the organisms with similar characteristics or features in the same group. Also, studying the time period in which the dinosaur may heave existed may also help to classify the dinosaur.
Classifying extinct species is difficult because one cannot determine the exact features pf the extinct species which help to predict the groups in which the organism is to be placed.

What can you conclude about the water quality of Sandy's pond over the past year? Explain. (5 points)
The water quality of the pond is worst in month of June and July. And the pH of the pond is mostly acidic, but went from alkaline in month of April. A.
Explanation:The pond quality assessment requires the measure of the pH of the water of pond and the number of colonies of bacteria and presence of other organisms in pond and their assessment. The report given here shows the variation of pond water pH for about 10 months and the colony count per liter for 10 months.
Here in the graphs given, we can see that the pond water quality got worst in month of June and July, because in those months, the water got the most number of faecal coliform bacteria. This is mainly because the months of June and July are the monsoon season, and the water sweeping from different areas of soil got the fecal coliform bacteria into the pond which helped in their growth and increased numbers.
In the month of March, the pH got to the highest of 7.5 which is because the March season don't generally get too much rainfall which is why the water concentration decreases and the growth of different other bacteria and plants make the water alkaline.
Cheetahs are one example of a population that has very limited genetic variation.
Which of the following groups of animals are most likely to have a limited variety in the genetics of their population?
Question options:
A. animals that have a very large population.
B. animals that live on more than one continent.
C. animals on the endangered species list.
D. animals that live in both hot and cold climates.
Answer:
Animals on the endangered species list.
Explanation:
An endangered species has very limited genetic variation (e.g Cheeta). The population of the cheetah that is already near to extinct is less likely to evolve much in response to the changing environment. The less chances of surviving are because of lesser chances of carrying positive mutations and diverse gene pool development during crossing. Hence, cheeta is an example of a population that has less chance of variation.
Which of these is a description of the relation?
Reaction velocity decreases with an increase in temperature.
Reaction velocity always increases with increase in temperature,
Reaction velocity remains constant with an increase in temperature.
Reaction velocity increases up to a certain temperature before decreasing,
D)
Answer:
The correct description of the relation is reaction velocity always increases with an increase in temperature (option B).
Explanation:
A chemical reaction can be affected by a variety of factors, including the concentration of reactants, pressure and temperature. In the case of temperature, the reaction rate increases depending on the temperature increase.
In a chemical reaction, a temperature -or heat - elevation results in an increase in the speed of motion of each component's particles, while increasing energy and effective shock between them.
Reaction → heat → increased energy → greater effective shocks of particles.
As a result of this, the relationship between reaction velocity and temperature is that at a higher temperature makes a reaction faster.

translate dna into tRNA
Answer AND Explanation:
Transcription is the process of creating a complementary RNA copy of a sequence of DNA. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as a complementary language that enzymes can convert back and forth from DNA to RNA. During transcription, a DNA sequence is read by RNA polymerase, which produces a complementary, antiparallel RNA strand. Unlike DNA replication, transcription results in an RNA complement that substitutes the RNA uracil (U) in all instances where the DNA thymine (T) would have occurred. Transcription is the first step in gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcript. Some transcripts are used as structural or regulatory RNAs, and others encode one or more proteins. If the transcribed gene encodes a protein, the result of transcription is messenger RNA (mRNA), which will then be used to create that protein in the process of translation.

What is a process that can occur in ocean due to the uptake of extra atmospheric co2
Ocean acidification is a process that can occur in ocean due to the uptake of extra atmospheric [tex]Co_2[/tex]
Explanation:
Ocean acidification is happening since abundance carbon dioxide [tex](Co_2)[/tex] in the environment is being caught up in the outside of the sea at an expanding rate. Regularly, sea water is less acidic than freshwater. As such the sea assimilates increasingly more carbon dioxide from the climate, it turns out to be progressively acidic.
This process of [tex](Co_2)[/tex] brings about more hydrogen particles, which builds the causticity of the sea. So this Ocean acidification is a procedure that can happen in the sea because of the take-up of extra biometric.

What is the affect of grey water on plants
Grey water can be beneficial for plant irrigation as it reduces the demand for freshwater, but it may contain harmful substances that can affect plant health depending on the content of the grey water and the type of plants.
Grey water, which is the wastewater from domestic activities like laundry, dishwashing, and bathing, can be reused for irrigating plants in gardens and landscapes. However, the effects on plants depend on various factors such as the presence of bacteria, heavy metals, organic pollutants, and the specific needs and sensitivities of the plants being irrigated.
On one hand, reusing grey water for irrigation can be beneficial by providing a source of nutrients and reducing the need for freshwater resources. On the other hand, it may contain substances that are potentially harmful to plants. For example, certain detergents contain salts and chemicals that can build up in the soil and negatively affect plant growth. Additionally, pollutants like pharmaceuticals or personal care product residues might be present in grey water and could pose risks to plant health.
Lionfish, indigenous to the Indian Ocean, have been found in the Atlantic Ocean since their accidental release in the late 20th Century. These fish feed on the same species as local snapper and grouper. They can also impact coral reef ecosystems by consuming herbivores, which keep the algae populations in check. Which statement explains why the lionfish populations continue to increase in the Atlantic and the impacts of the lionfish on marine ecosystems continue to be observed?
A) Lionfish have no natural predators in the Atlantic, so there is a lack of population control for these fish.
B) Lionfish have a narrow range of temperature tolerance and salinity, so they only reproduce exponentially in the Atlantic.
C) Lionfish have symbiotic relationships with coral reef species that increase the populations of native and invasive species.
D) Lionfish migrate to the aphotic zone of the ocean to spawn, which has no light and reduces the visibility of the eggs for parasites.
Answer:
The correct option is A) Lionfish have no natural predators in the Atlantic, so there is a lack of population control for these fish.
Explanation:
The description in the question tells that the lionfish is not a native in the Atlantic ocean. As a result, it does not have many predators in that ocean to keep a balance on the population of the lionfish species. As a result, the population of the lionfish increases as it has an abundant supply of preys but not enough predators which will feed on it. Hence, the population of the lionfish continues to increase in the Atlantic.
Answer: the correct answer is below
Lionfish are native to the Indo-Pacific region. However, a hurricane caused six fish from an aquarium to accidentally be swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to rapidly increase in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of ocean. These fish have predators such as sharks and scorpion fish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food. Their one predator is humans, who have recently started fishing them for food. In the Atlantic Ocean, algae and seaweed are producers. Small fish, crabs, and other crustaceans make up the first and secondary consumers. Sharks and orcas are some of the larger predators, which are also consumers. Bacteria and fungi are the decomposers that break down food. Lionfish are consumers because they eat fish and small crustaceans.
Explanation:
Kai looks at a photo of herself with her parents. She notices that, while her features are similar to her parents’ features, they do not appear to be identical.
Which explains why this is the case?
Their DNA is made of different codon sequences.
Their DNA is made of four different bases.
Kai inherited more proteins from one parent than the other.
Kai inherited different amino acids from either of her parents.
Answer:
A
Explanation:
Just took the test
The best explanation as to why Kai is not identical to her parents is because their DNA is made of different codon sequences.
When it comes to expressing genes, the information on organisms' DNA sequence is first transcribed as codes into an mRNA. The coded information is then translated as proteins in a process known as protein synthesis.
Thus, for two organisms to be identical, the information on their DNA must be exactly the same. In other words, the codon sequence on their DNAs must be the same. Once there is a variation, different messages would be translated and this will tell as variations on the physical appearances of the organisms.

What happens when hydrochloride is added
Answer:
"Hydrogen gas and iron chloride are produced" happens when hydrochloride is added.
Explanation:
The iron chloride & hydrogen gas (with bubble formation) is generated by adding hydrochloric acid to the iron filings. The iron displaces hydrogen from hydrochloric acid to form iron (II) chloride & hydrogen gas. That is a single displacement reaction.The reaction is given as follows: Fe+2HCl⟶FeCl2 + H2 .
Further to conform that only these products are formed some analysis is done of the resulting solution and gas formed:
A pH measurement demonstrates that the solution becomes less acidic, thus hydrogen ions have been consumed. The addition of silver nitrate results in the formation of a white precipitate indicating that the chloride ions are still present in solution.1.

No stripe on the head (H) is dominant, a black stripe on the head is recessive. If dad's genotype is Hh, what are the odds that the offspring will have a stripe?
Select one:
a. 50%
b. 100%
c. 0%
d. 25%
The chance of the offsprings with stripe on head is 50%.
Option A.
Explanation:Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.
So the genotype of the father which is given as Hh. He is heterozygous.
The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.
So the gametes from father is H and h. Whereas the gametes from mother is only h.
So the genotype of the offsprings are Hh and hh as 50% each.
So the probability of the offspring being striped head is 50%.

An occluded front moves over farmland that has been experiencing drought conditions.
Which change in weather will this front likely bring?
an extended period of rain
more dry air and sunny skies
gray skies, but no rain
violent, short-lived thunderstorms
Answer:
This honestly depends on whether it is a cold or warm occuluded front. Cold occluded fronts bring violent storms like hail and thunderstorms and have also caused tornadoes. Warm occluded fronts typically produce light rain.
Best answer is : An extended period of rain
Explanation:
Occluded Front Forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Can bring strong winds and heavy precipitation.
