A student was interested in comparing sunblock lotions, which contain
chemicals that protect the skin from sunburn. The student purchased three
different brands of lotion at three different prices and performed an
experiment to see which one best protected the skin. The lotions cost $3,
$5, and $7 for an 8-ounce bottle. The sun protection factor (SPF) was 30 for
all three lotions. The student applied equal amounts of each lotion next to
each other on one of her arms. The three areas covered by the lotions were
the same size. The student observed the three areas for color change after
two hours of Sun exposure. Identify one condition that were held constant
in this experiment. *

What are the errors and explain why
Answer:
1. Oxygen
2. Glucose
3.Light energy
Explanation:
1. Oxygen is not needed by the plant for photosynthesis.
It is a by-product of photosynthesis. Instead Carbondioxide is needed.
2. The glucose produced does not stay solely in the plant, part of it is used up by the plant while others stores in edible parts of the plant that men use as food.
3. The light energy converts H2O to 4H+ and 4OH- needed in the synthesis of carbohydrate and release of Oxygen.
Question
If a rose plant has a genotype of Ffgg, what are the possible genetic combinations of offsprings that could be
present from this plant?
Answer:
Suppose you have a parent plant with purple flowers and a parent plant with white flowers. Because the b allele is recessive, you know that the white-flowered parent must have the genotype bb. The purple-flowered parent, on the other hand, could have either the BB or the Bb genotype. The Punnett square in Figure below shows this cross.

What is the carbon cycle
Answer:
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.

Ralph and Cory are friends on their way to a big party. Cory is familiar with the party's hosts and seems to always know what to say to be the life of the party. Ralph, who has never engaged with this group, is unsure of how to act or participate. What can be said of Ralph and Cory?
Answer:
Ralph is more stressed by the situation because Cory has a better set of social skills than Ralph.
Explanation:
Social skills are attributes that make interactions with others easy and comfortable for people. The scenario shows that Cory is more lively and sociable, thus, his social skills are better than Ralph's. Ralph on the other hand is apprehensive because he is not very sociable and finds it difficult to manage his interactions with people.
Ralph's situation is worsened by the fact that he is unfamiliar with the people in the party.
Which is a common practice for farmers to yield higher crop production?
A) Overplowing mixes the nutrients in the soil
B) consistently plant the same crop every year
C) allow later-successional growth to replace nutrients
D) keep the area planted with early-successional species
NOT C
Answer: D) keep the area planted with early-successional species.
Explanation: Early successional species grow fast and spread their seeds rapidly and widely. This could help to bring in a potentially high crop yield.
It likely is not A because overplowing leaves the soil susceptible to erosion and damages the physical infrastructure.
B should not be the answer because consistently planting the same crop year-round can deplete the nutrient resource said crop relies on. It’s why crop-rotating is a thing now.

What causes clouds of dust and gas to form a protostar?
Answer:
Mainly the gravitational instability in the clouds of dust (molecular clouds)
Explanation: Stars are born within molecular clouds, which are mostly made of hydrogen and lesser amounts of helium and other heavier elements. The formation of a protostar begins when gravitational instability is present in the molecular cloud, caused by regions of higher density. Eventually, the clouds of dust start to collapse to due gravity, the protostar forms. The protostar, is still an underdeveloped star, meaning it does not perform nuclear fusion in its core, but it still produces its own heat from the extreme pressure.

The structure of a human skin cell differs from that of a human muscle cell. The two cells most likely have different __________. Choose the correct answer.
Answer:
The correct answer would be - functions.
Explanation:
The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.
In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.

is teeth and curly hair a recessive trait or dominate trait plz explain
Answer:
Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. But genetics are tricky, and there's a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring.

How do the Aleutian volcanoes differ from the Cascades volcanoes?
Answer:
Type of Convergence - Ocean to continent for Cascade/ Ocean to Ocean for Aleutian
Explanation:
If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate.
The features of an ocean-ocean subduction zone are the same as those of an ocean-continent subduction zone, except that the volcanic arc will be a set of islands known as an island arc.
The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
The Cascade Volcanoes are a group of volcanoes in western North America that stretch over 700 miles from southwestern British Columbia through Washington.
Where are Cascade volcanoes?The Pacific Northwest's skyline is dominated by active volcanoes. Volcanoes of the Cascade Range (Public domain.) The Cascade Range's familiar snow-capped peaks are part of a 1,300 km (800 mi) chain of volcanoes that stretches from northern California to southern British Columbia.The Cascade Volcanoes are a group of volcanoes in western North America that stretch over 700 miles from southwestern British Columbia through Washington and Oregon to Northern California.

Heredity is the passing on of traits from parent to offspring. Heritable information is important for life to continue. What is the role of meiosis in heredity?
Write your answer in the space below.
Answer:
Meiosis helps create more diversity and individuality in the genes of organisms.
Explanation:
Hope this is helpful, this is what I learned last year.
Answer:Sexual reproduction allows for the passing of traits from parent to offspring. In sexual reproduction, meiosis produces gametes that have chromosomes from the parents. The chromosomes carry genetic information. When the gametes fuse during fertilization, an individual with a unique combination of chromosomes or a unique genetic make up is formed.
