Explanation:
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:
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%

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??

And the fluid Outside the cell membrane is called:
cytoplasm; interstitial fluid
interstitial fluid: cytoplasm
interstitial fluid: tissue fluid
tissue fluid: interstitial fluid
In a cell, the fluid within the cell membrane is called cytoplasm, and the fluid Outside the cell membrane is called interstitial fluid. The correct option is A.
What is cytoplasm?The gelatinous solvent that fills the inside of a cell is known as cytoplasm. It is made up of water, salts, and organic molecules.
Certain intracellular organelles, including the nucleus as well as the mitochondria, are separated from the cytoplasm by membranes.
The cytoplasm of a cell performs all functions related to cell expansion, growth, and replication.
Interstitial fluid can be found in the spaces between cells. It is caused by substances leaking from blood capillaries.
It aids in the delivery of oxygen and nutrients to cells as well as the removal of waste products.
Glucose, salt, fatty acids, and minerals such as calcium, magnesium, and potassium are all found in interstitial fluid.
Interstitial fluid contains nutrients from blood capillaries. It can also contain waste products from metabolism.

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.

A. Inventing tools can help humans survive in their environment.
B. Overusing resources can make a survival practice unsustainable.
O .
C. Developing different religions can lead to conflict among
societies.
D. Having opposable thumbs helps humans grasp objects.
Answer : A
Explanation:
Inventing tools can help humans survive in their environment. Therefore, option (A) is correct.
Why inventing tools help human survive?Culture refers to the shared beliefs, values, practices, and knowledge that characterize a group or society. Humans have relied on culture to survive and thrive for thousands of years. Inventing tools is an example of how culture can help humans survive. By creating and using tools, humans are able to adapt to and manipulate their environment to meet their needs. For example, early humans used tools to hunt, gather food, and build shelters, which helped them survive in their environment.
Overusing resources can lead to unsustainability and environmental degradation, which can threaten human survival. Developing different religions can lead to conflict among societies and does not necessarily help humans survive. Having opposable thumbs is a physical adaptation that has helped humans develop complex motor skills, but it is not an example of how culture helps humans survive.
