Answer:
The sun uses some of its own mass during fusion reactions.
Explanation:
This is because the sun consist of hydrogen and helium. And the sun gravity compresses the gases hydrogen and helium and they become hot.
Heat and pressure forces hydrogen together to form helium which is nuvlear fusion.
Nuclear fusion is the combination to two nuclei or more nuclei to form one or more subatomic nuclear.

Which is larger, 40 centimeters or 670 millimeters?
Answer:
670 Millimeters
Explanation:
1 Millimeter = 0.1 Centimeter
670 millimetres is equal to 67 cm which is greater than 40 cm. So 670 mm is greater than 40 cm.
What is a millimetre?It is a unit of measurement for length/distance. It is a very small unit of measurement. It is a visible unit of measurement, unlike a micrometre which is smaller than a millimetre but measures things that are not visible to the unaided eye.
It is a part of the metric system commonly used in Science, Technology Engineering and Mathematics (STEM). A millimetre is measured as one-thousandth of a metre.
The word metre is derived from a Greek word which means measure. The metric system that is used internationally for the measurement of various quantities is based on decimals.
Like a millimetre is one-thousandth of a metre, a micrometre is one-millionth of a metre. A centimetre is one-hundredth of a meter and a quantity smaller than a micrometre called a nanometer is one-billionth of a meter.
Therefore, 670 mm is 67 cm which is greater than 40 cm.

Some scientists are modifying the genetic code of certain fish by inserting genes that cause the fish to produce more growth hormone, which causes the fish to grow more quickly. Salmon is one type of fish on which scientists are working. Which answer choice shows the most significant negative impact to society that could result from producing genetically modified salmon?
Salmon cells could become less responsive to the hormone over time, slowing the growth rate of the fish.
Salmon could be reintroduced into the ecosystem where they could breed with, and alter, populations of wild salmon.
The genetically modified salmon will be very expensive to raise, so the fish will be too expensive for people to buy.
The modified, farmed fish would be more difficult for predators to hunt than wild salmon if reintroduced into the ecosystem.
Answer:
breeding with and altering the population of wild salmon
the extra growth hormone could change the wild salmons reproductive fitness, could slow them down or make them less fertile or more fragile so they aren't able to spawn etc and reduce the wild population of salmon which would have large effects
there is a rainforest in BC that's survival relies on the nutrients that salmon bring when they spawn and die
It could also be scare mongering and have no negative effect, could be a net positive??

Can someone please give a small description on these words based off of animals cell
Golgi body
Cell membrane
Centrosome
Nucleus
Vacuole
Mitochondrion
Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve. Determine the F1 results of a cross between true-breeding red and true-breeding mauve flowered plants.
Answer:
F1) 100% bbRr, red flowered plants.
Explanation:
Available data:
flowers may be yellow, blue, red, or mauvecolors may be true-breedingthe cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowersF2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).
According to the first cross, we might establish the following genotypes:
1st Cross: blue-flowered plant x red-flowered plant
Parentals) BBrr x bbRR
Gametes) Br, Br, Br, Br bR, bR, bR, bR
F1) 100% BbRr, yellow plants
Parentals) BbRr x BbRr
Gametes) BR, Br, bR, br
BR, Br, bR, br
Punnett square) BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
F2) 9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR
3/16 blue ------> 1/16 BBrr + 2/16 Bbrr
3/16 red---------> 1/16 bbRR + 2/16 bbRr
1/16 mauve ----> 1/16 bbrr
So,
Yellow-flowered plants: BBRR, BBRr, BbRR, BbRrRed-flowered plants: bbRR, bbRrBlue-flowered plants: BBrr, BbrrMauve-flowered plants: bbrrAccording to these genotypes, the second cross would be like following,
2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.
Parentals) bbRR x bbrr
Phenotype) Red Mauve
Gametes) bR, bR, bR, bR br, br, br, br
Punnett square) bR bR bR bR
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
F1) 100% bbRr, red flowered plants.

Answer:
The answer is Cytoplasm
Explanation:

Answer:
Adenine (A) = 28%
Cytosine (C) = 22%
Explanation:
The DNA molecule, which is the genetic material that stores or holds information needed by the cell for growth, reproduction etc. Structurally, the DNA is composed of nucleotide subunits, which are of four types namely; Adenine, Guanine, Cytosine, and Thymine etc.
According to Chargaff in his complementary base pairing rule, he states that Adenine will always pair with Thymine (A-T) while Guanine will always pair with Cytosine (G-C). Based on this, Chargaff further stated that the amount of adenine must be equal with that of thymine while that of guanine must be equal to cytosine.
In total, their total amount must be equal to 1 or 100% i.e. (A + T) + (G + C) = 100%. In this question, 22% of Guanine are found in the DNA of a fox. This means that automatically, the percentage of cytosine is 22%. We then calculate the amount of Adenine and Thymine as follows:
(A + T) + (G + C) = 100%
A + T + 22 + 22 = 100
A + T + 44 = 100
A + T = 100 - 44
A + T = 56
Since A = T,
56/2 = 28
Hence, A = 28%, T = 28%
1-Brown eyes (B) are dominant to blue eyes (b). Straight hair (H) is dominant to curly hair (h). Free earlobes (E) are dominant to attached earlobes (e). If individual one who has the genotype BbHhEe is crossed with individual two who has the genotype bbhhEe, what is the probability that their offspring has brown eyes, straight hair, and attached earlobes?(I asked last time but I didn't get a serious answer, please make your answers as one percentage.)
Answer:
The correct answer would be - 1/16 or 6.25% is the probability that their offspring has brown eyes, straight hair, and attached earlobes
Explanation:
In this question, it is given that-
1. Brown eyes (B) are dominant to blue eyes (b)
2. Straight hair (H) is dominant to curly hair (h)
3. Free earlobes (E) are dominant to attached earlobes (e)
Now the cross between BbHhEe (Brown eyes-straight hair-free earlobe) with bbhhEe (blue eyes-curly hair-free earlobe) takes place.
Gametes will be -
BbHhEe - BHE, BhE, Bhe, BHe, bHE, bHe, bhE, bhe
bbhhEe - bhE, bhe
cross would be -
BHE BhE Bhe BHe bHE bHe bhE bhe
bhE BbHhEE BbhhEE BbhhEe BbHhEe bbHhEE bbHhEe bbhhEE bbhhEe
bhe BbHhEe BbhhEe Bbhhee BbHhee bbHhEe bbHhEe bbhhEe bbhhee
By the Punnett cross, we get only one out of 16 offspring with brown eyes, straight hair, and attached earlobes
Thus, the correct answer would be - 1/16 or 6.25% is the probability that their offspring has brown eyes, straight hair, and attached earlobes
