A 40 watt filament light bulb and a 100 watt filament light bulb are connected in series to a battery. Which bulb will glow brighter? Why? Explain.
Answer:
100 watt
Explanation:
In parallel the 100w bulb will glow brighter.
The 100w bulb has a lower resistance of the two. That’s why it uses more power normally.
In series, the same current must flow through the two bulbs. And beacuse the power in each bulb is proportional to the resistance, keeping the current constant, the bulb with the highest resistance will glow brightest.
Ignoring the effect of the heat if the filaments. As the resistance in the glowing wire increases with temperature, the bulb with the highest resistance will glow proporitionally more than the power difference suggests. Likely the 100w bulb will not glow at all.

Answer:
The correct answer is "A. DNA". Nucleotides are the parts or links that constitute nucleic acids and DNA is a nucleic acid that stands for Deoxyribonucleic Acid. It does not matter if the sample studied is from a silk moth or other species; the DNA strand can only be represented by the letters A, C, G, and T. In this case, the DNA sequence is represented by CAGACT.

What would be the complementary strand of mRNA
Answer:
the complementary nucleotide to adenine.
Explanation:
mRNA is formed as a complementary strand to one of the two strands of the DNA. Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as

It is even common for scientists to insert genes into an organism from an entirely different organism.
Explanation:
The colors of stained glass are metallic oxides (combinations of
different metals and oxygen), but the beautiful colors you see aren't
due solely to the coloring in the glass. It's the light passing through
the glass that reaches your eyes. The natural light changes from
morning to night, even from moment to moment. Our perception of
stained glass changes with the light.
Answer:
Yes.
Explanation:
Our perception of stained glass changes with the light because light is the main thing which allows us to see the colour of stained glass. Light has several colour but we can see them when it pass through a specific medium such as prism. The stained glass also act as a prism which allow us to see different colour when the light passes through this glass so we can say that light is responsible for the appearance of colour.

What climate changing causes are not in human control
Explanation:
The climate is changing — the thing is, it isn’t just due to humans.
Natural forces beyond human control are also gradually affecting our climate. These geophysical forces are vital to understanding global warming. Man is indeed responsible for a large portion — possibly even a majority — of global warming. But also in play are complex gravitational interactions, including changes in the Earth’s orbit, axial tilt and torque.
This fact needs to be included in the public debate. Because these gravitational shifts, occurring over millennia, can influence climate patterns and ultimately lead to noticeable variations in seasons. Interestingly, research suggests climate change can alter the tilt of the Earth, but an unrelated change in tilt can also further change the climate. It is a balance-counterbalance relationship.
Changes in the Earth’s path around the Sun, or eccentricity, involve shifts in the orbit around the Sun from a roughly circular journey to more of an elliptical one. When the Earth gradually adopts a more elliptical orbit, there are more pronounced temperatures during the summer and winter months. This alteration is exacerbated when the Earth’s axial tilt is inclined to a sharper degree than usual. As this happens, it causes the North and South Poles to be positioned more directly toward the Sun.
Haven’t you noticed the recent rise in irregular weather patterns? This is not just a man-made problem. Gradual slight variations in the Earth’s orbit around the Sun can strongly influence temperature extremes. This is important because the conversation around climate change has become so politicized, we've totally lost sight of the science — and with it, any room for bipartisanship.

Why is exponential growth usually very rare in nature
Answer:
Explanation:
The scarcity of natural examples is due to the fact that there are population controls due to a limiting amount of resources such as food, light, shelter, water as well as to factors such as predation, climatic change, and disease.
Answer:
In the real world, with its limited resources, exponential growth cannot continue indefinitely. Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals gets large enough, resources will be depleted and the growth rate will slow down.

What enzyme in organisms is Taq Polymerase similar to? Why?
Taq polymerase is a common enzyme used for PCR amplification. It is similar to E. coli DNA dependant DNA polymerase I. It is so because of the strong homology at the amino acid level. The 3′-OH nucleotide addition site, the dNTP/DNA binding sites, and the 5′-3′ exonuclease sites of both the enzymes.
What is E. coli DNA dependant DNA polymerase I?The DNA polymerase I is mainly used for repair of the damaged DNA. It also helps to connect Okazaki fragments by deleting RNA primers.
E. coli DNA dependant DNA polymerase I has similar properties like Taq polymerase as they both have strong homology at the amino acid level.
The 3′-OH nucleotide addition site, the dNTP/DNA binding sites, and the 5′-3′ exonuclease sites of both the enzymes.
Thus, it can be concluded that E. coli DNA dependant DNA polymerase I is the enzyme similar to Taq polymerase.

Explanation:
A charity group wants to give away insect-resistant corn seeds to farmers in poor countries. One of the main insects that harms corn crops in these countries is the corn rootworm.
To decide which type of corn to give away, the charity group tests 4 types of corn to see which one the corn rootworms like least.
Data from Rootworm Test
Corn Sample
Name Plant Height
(in feet) Attacked by
Rootworm? Ear Length
(in inches) Pounds per
acre
A 7 yes 8 650
B 4 no 4 2400
C 6 yes 5 1260
D 5 yes 7 450
Some of the farmers receiving the seeds want to grow the corn with the biggest ears because they think this corn will produce the most food per acre. Other farmers think that the tallest plants will produce the most food per acre.
Based on the group's research, which type of corn resists the corn rootworm best and therefore produces the most corn per acre?
A.
Sample B
B.
Sample A
C.
Sample C
D.
Sample D
Answer:
Sample B
Explanation:
The rootworms don't attack it
Answer:
Sample B
Explanation:
When people put time, money, or effort into reaching a goal, such as helping feed people in poor countries, they need scientific evidence to help make decisions. This is because the solution that seems right might not actually be the best one once all the evidence is studied.
While it seemed that the tallest plants or the plants with the largest ears would produce more corn, the scientific evidence showed that this was not true, at least when the corn was attacked by the corn rootworm.
The charity group's research shows that Sample B resists the corn rootworm best and therefore produces the most corn per acre.
In humans, brown eyes are generally dominant over blue eyes. Find the phenotypic and genotypic ratios of a cross between two heterozygous brown-eyed people. Choose This is a required question
Answer:
Brown eyed genotype: Aa (eterofzygous) or AA (homofzygous)
The genotypes derived from the cross are: AA, Aa, Aa, aa
The phenotypes are: 3 with brown eyes and 1 with blue eyes (aa)
The phenotypic ratio is 3:1 (brown eyes: blue eyes) and the genotypic ratio is 1:2:1 (dominant homozygous: heterozygous: recessive homozygous).
What happens in a heterozygous cross?In humans, the allele for brown eyes (B) is dominant over the allele for blue eyes (b). Heterozygous individuals, who carry one copy of each allele (Bb), will have brown eyes.
When two heterozygous brown-eyed individuals (Bb) cross, the possible genotypes of their offspring are:
BB (brown eyes): 25% chance (homozygous dominant)
Bb (brown eyes): 50% chance (heterozygous)
bb (blue eyes): 25% chance (homozygous recessive)
So, the genotypic ratio of the offspring is 1:2:1 (BB:Bb:bb).
As for the phenotype, the only possible one is brown eyes and it occurs in 75% of the offspring (25% BB + 50% Bb)
Therefore, the phenotypic ratio of the offspring is 3:1 (brown eyes: blue eyes)
It's worth noting that while this is the typical outcome of crosses involving the eye color genes, it's not universally accurate, as other factors and genes might have an influence on the phenotype. Additionally, in reality, eye color is a complex trait and many other genes are involved not just B and b, so the dominance is not always that clear.

Explain how Chromosomes are like a ball of yarn (use the words chromosome, DNA, and gene in your answer)
Answer:
Chromosomes are like a ball of yarn in the sense that there are multiple components that make up the structure. Genes can be in similitude of the smallest threads in the yarn and when a multitude of genes are put together they make a DNA strand or a long, thick thread of yarn. Lastly, when DNA is twisted together, it becomes bundled together, making a chromosome or a "ball of yarn".

Predict:
Observe:
Explain:
Answer:
If green house gas emissions do not decrease the globe will increasingly get warmer. The sun's heat enters the atmosphere, some heat will escape, some will be trapped. Carbon dioxide causes the heat to remain in the atmosphere. Without carbon dioxide Earth would very cold, but with the use of fossil fuels and other unsustainable resources we are releasing too much carbon dioxide in the atmosphere. This is causes way too much heat to remain trap. And this is what is causing global warming
