Answer:
The person's risk of cardiovascular disease would increase.
Explanation:
saturated refers to all single bonds in the hydrocarbon chain, meaning no kinks in the chain. The hydrocarbon has the most number of carbons it can have, as there are all single bonds. If the hydrocarbon has even one less carbon, there would be kink, and it would be unsaturated and liquid. Our body needs less carbon, so unsaturated fats are better. But having saturated fats means no liquid, rather solid, which means harder for the blood to get to the heart. So your risk would cardiovascular disease would increase

Some scientists argue that global warming is related to
buming fossil fuels to produce energy
o increased use of fertilizers
loss of forested areas
a of the above
Answer:
all of the above
Explanation:
1. Based on the trend depicted in the graph, explain what you
think the relationship might be between organisms
performing respiration and the organisms performing
photosynthesis in this area of the world.
2. What effects might this steady increase of carbon dioxide
have on the organisms living in this area?
3. Describe the changes you would expect to see to this graph
if the population of cyanobacteria increased dramatically in
the ocean water surrounding Hawaii in 2003. Explain your
predictions.
1. The process of photosynthesis and respiration are often found in the same organisms, so they are directly connected. In this case, we have significant increase in the levels of carbon dioxide, and carbon dioxide is a crucial element in the process of photosynthesis. The more carbon dioxide there is, the more organisms can perform photosynthesis. Once the organisms are able to perform photosynthesis, the next step is that they need to use the created sugars from it to convert them into energy. The sugars combined with oxygen produce the energy for growth, thus we can say in this case that the increase of carbon dioxide has increased the amount of photosynthesis, which increased the amount of respiration.
2. The steady increase of the carbon dioxide will result in higher temperatures because it is a greenhouse gas that has the ability to trap the heat. This means that organisms that are better suited for warmer climates will thrive, while the others will either have to adapt, or go extinct. Also, the higher amount of carbon dioxide and warmer weather conditions will result in longer growing season, thus more producers will be able to thrive as the carbon dioxide is crucial for them to perform photosynthesis.
3. If the population of cyanobacteria starts to increase dramatically, then the area will experience multiple changes. The cyanobacteria will extract large amounts of carbon dioxide from the atmosphere, thus lowering its levels, while in the same time releasing large amounts of oxygen in the atmosphere. The graph will start to look much different as the carbon dioxide curve will be heading downward, and if the trend continues it will go even lower than its starting point of measurement in 1958, resulting in colder weather conditions and changes in the environment.
The relationship is inverse due to increasing the level of carbondioxide in the atmosphere.
There is a inverse relationship in the graph between organisms performing respiration and the organisms performing photosynthesis in this area of the world because the concentration of carbondioxide gas increases which shows us the increase of respiration rate as compared to the rate of photosynthesis.
The organisms present in this area experiences change in the climate which lowers their chance of survival. If the population of cyanobacteria increased dramatically in the ocean water then the concentration of carbondioxide gas in the atmosphere begins to decreases due to fixation of cyanobacteria so we can conclude that the concentration of carbondioxide gas decreases in the atmosphere.

which of the following requires the use of energy to move a molecule across a cell membrane?
A. Active transport
B. Simple diffusion
C. Osmotic pressure
D. Facilitated diffusion
Answer:
A. Active transport is the correct answer.
Explanation:
Active transport requires the use of energy to move a molecule across a cell membrane.
Active transport is a process in which molecules move against the concentration gradient.
To move the molecules from the lower concentration region to the higher concentration region active transport use energy in the form of Adenosine Triphosphate(ATP).
ATP gives the needed energy for the active transport process to move the molecules across the cell membmbrane or concentration gradient.
Sodium potassium pump is a type of active transport it uses energy to transport the sodium ions and potassium ions inside and outside of the cells.
Finches living on the Galapagos Islands were critical for Darwin to develop his ideas. What key observation did he make about the finches?
A. The finches' beaks were colored differently, providing camouflage within their unique environment.
B. The finches' feathers were colored differently, providing camouflage within their unique environment.
C. The finches' beaks were uniquely adapted as tools for them to eat the food that was available to them.
D. The finches' feathers were structurally different to allow them to fly at different heights and speeds, depending on their local environment.
The finches' beaks were uniquely adapted as tools for them to eat the food that was available to them. Therefore, option (C) is correct.
The Galápagos Islands are located in close proximity to the coast of South America. The finches migrated from there to these islands. Finches were observed by Darwin to be varying on each island he explored. He noticed that the finches had beaks of varying colours.
He noticed that the food available varied on different islands, in addition to the difference in colour.The sizes of seeds were different on different islands. Okay, so the finches were able to adapt to their environments based on the types of food that were available. This made it easier for them to survive.

1. Answer: A
Explanation: For a cell to form proteins, the specific types of proteins are coded for by the genes in DNA (found in the chromosomes of the nucleus). To produce proteins, the genes are first transcribed by RNA polymerase to form messenger-RNA. The mRNA is then translated into proteins by ribosomes in the cytoplasm of the cell.
2. Answer: B
Explanation: Translation of genes into proteins is dependent on the sequence of nucleotides. They are translated in sequences of 3 nucleotides known as codons. Therefore adding a nucleotide on a piece of DNA causes what is referred to as a frame-shift mutation. The 3 sequences (of codons) is interrupted and shifted by one nucleotide. Therefore, the codons change and the amino acids translated will also change.
3. Answer: A
Expanation: Producers are significant in a food chain because they incorporate the energy of the sun into the food chain. This is why they are at the base of the food chain and have the largest biomass. They are consumed by primary consumers which are consumed by secondary consumers which are consumed by tertiary consumers and so on.
4. Answer: D
Explanation: Plants are consumed by herbivores. Therefore, a decrease in plant population due to drought was resulted to decrease in herbivore population. This is due to stiff competition by the herbivores for the scarce plant population. Carnivores consume herbivores. Due to a decrease in the herbivore population, then the carnivore population would also decrease.
5. Answer: A
Explanation: Burning of fossil fuels emits carbon dioxide gas which is a greenhouse gas. Greenhouse gas traps infrared wavelength of lights hence warming up the atmosphere, causing global warming. Reduction in use of fossil fuels will hence alleviate an increase in global temperature hence protect coral in the oceans from bleaching.

what factor makes the Hawaiian islands the perfect place for plant species to diversity
Answer:
The nutrient-rich soils.
Explanation:
The Hawaiian Islands surfaced between 400,000 and 5 million years ago. However, the entire undersea chain has been in existence for over 60 million years! Still, in geologic terms, the Hawaiian Islands are relative newcomers to Earth. These islands are isolated in the middle of the Pacific Ocean. They were created by volcanic activity from the "hot spot" in Earth’s crust. These underwater mountains eventually surfacecreating islands. The resulting volcanic soil is rich in nutrients. As Hawaii is located in a tropical region, the climate provides warm temperatures and an ample water supply. These resources provide all the requirements to support an abundance of plant life. An unoccupied landscape offers a wide variety of empty niches. This is the perfect recipe for plant diversification.
Its tropical location, Hawaii, enjoys mild temperatures and a sufficient supply of water. The climate offers comfortable temperatures and a plentiful supply of water. Resulting volcanic soil is rich in nutrients.
What is Tropical forest?Closed-canopy forests called tropical forests are those that are found within 28 degrees north or south of the equator.
They are extremely wet areas that see more than 200 cm of precipitation annually, either seasonally or year-round. The temperature ranges from 20 to 35 degrees Celsius.
The tropics of Cancer and Capricorn roughly define tropical woods, which are forested landscapes in tropical places that may also be influenced by other variables like prevailing winds.
It might be challenging to classify certain types of tropical forests. Tropical rainforests are found in Central and South America, western and Central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.
Therefore, nutrient rich soil makes the Hawaiian islands the perfect place for plant species to diversity.

How are mitosis and meiosis similar
Final answer:
Mitosis and meiosis are both forms of cell division. Mitosis results in two genetically identical diploid cells, while meiosis results in four genetically distinct haploid cells.
Explanation:
Mitosis and meiosis are both processes of cell division that occur in eukaryotic cells and are preceded by one round of DNA replication. However, they differ significantly in their purpose and outcome. Mitosis involves a single nuclear division, resulting in two daughter cells that are diploid and genetically identical to the parent cell. In contrast, meiosis involves two nuclear divisions and results in four daughter cells that are haploid and genetically distinct from one another and the parent cell. While both processes involve stages such as metaphase and telophase that are comparable, the meiotic process also includes unique events such as anaphase I, leading to a halving of chromosome numbers.

Hello Midoria, thank you for asking a question here on Brainly!
You Asked ➤ What is the approximate relative humidity in the situation shown below?
↴ OUR CHOICES ↴
A: 9%
B: 21%
C: 30%
D: 44%
------------------------------------------------------------------------------------
Answer ➤ D: 44%
Explanation: To solve this problem, we need to know the formula on receiving the wet bulb depression shown on the thermometers. While looking at this image, I can see there is a dry bulb and a wet bulb. We know that dry bulb is 29.8 degrees and that the wet bulb is 20.9 degrees. If we find the difference, we will solve for the depression.
➤ 29.8 - 20.9
➤ = 8.9 degrees Celsius
The next step is to look at the psychrometric table you have by the timer and thermometer and figure out what the approximate relative humidity is by looking for the row that matches the dry bulb and wet depression temperature to the nearest value.
➤ The nearest value to 29.8 degrees (the dry bulb) is 30 degrees.
➤ The nearest value to 8.9 degrees is 9 degrees.
Find which value intersects with the row and column of the table. We can see that the value intersect at 44 percent from the row and column of the graph. That is our final approximate relative humidity.

if there are 300 worms in 100m2 of lawn , what is there population density
Answer:
3 worms per square meter
Explanation:
In order to get to the population density of the worms, we need to take a basic measurement for it. Since we have a land area in square meters, we will take the square meter as a basic unit. On the land of 100 square meters, we have 300 worms. In order to get to the result we need to use the simple formula for population density:
population density = population / land area
300 / 100 = 3
So we have a result of 3, thus meaning that the population density of the worms is 3 worms per square meter.
In sedimentary rock the oldest fossils would be expected to be found
Answer:
At the bottom of the sequence
Explanation:
According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.
The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.
This why relative dating of rocks can be possible.

a punnett square is used to determine the __
Final answer:
A Punnett square is a tool used in genetics to predict the genotypic and phenotypic ratios of offspring resulting from a cross between two parents, by taking into account the combinations of alleles and the rules of probability.
Explanation:
A Punnett square is used to determine the expected genotypic and phenotypic ratios of offspring from a genetic cross between two parents. When demonstrating a monohybrid cross, such as that between true-breeding pea plants with yellow and green seeds, the Punnett square visualizes all the possible combinations of alleles. For instance, with yellow seeds being the dominant trait (allele Y) and green seeds being recessive (allele y), a cross between a YY and a yy parent would result in all Yy offspring, predicting only yellow seeds in the first generation. This device makes it easier to see the statistical probabilities of inheriting certain traits.
To further illustrate, if we cross a white-eyed male fruit fly with a female that is heterozygous for red eye color, we would use a Punnett square to lay out the possible gene combinations and determine the ratio of offspring that will have the red or white eye color trait. By following the rules of probability and the pattern of inheritance (dominant and recessive traits), we can predict the phenotypic ratio of the offspring.
A Punnett square is used to predict the genotypic and phenotypic ratios of offspring from a genetic cross, showcasing the potential genetic makeup and expected physical traits based on the combination of parental alleles.
Explanation:A Punnett square is a diagram that is instrumental in predicting the genotypic and phenotypic ratios of offspring resulting from a genetic cross. Created by British geneticist Reginald Punnett, the Punnett square represents the different possible allele combinations from the parental gametes, thus showing the potential genetic makeup of the offspring.
For example, when crossing a true-breeding pea plant with yellow seeds (YY) with one having green seeds (yy), a Punnett square helps to visualize that all offspring will have the genotype Yy. This results from the dominant yellow seed allele (Y) masking the effect of the recessive green seed allele (y), leading to all offspring displaying yellow seeds. By applying the rules of probability, a Punnett square can show that each box, representing a potential zygote, has an equal chance of occurring, thus yielding the expected genotypic ratio among the offspring.
