4. The phenotype ratio is 2:2
5. 50% has tall and yellow seeds
6. Genotype for tall and green seed is TTGg, TtGg
Explanation:
The parent 1 is homozygous tall, yellow seeds, therefore the genotype is TTgg, While parent 2 is herezogous for both traits, therefore the genotype is TtGg.
Crossing the two parents gives children with the following traits:
Parent 1 gamete: Tg Parent 2 gamete: TG Tg tG tg
TTGg, TTgg, TtGg, Ttgg
The cross gives: TTGg, TTgg, TtGg, Ttgg
Therefore, 2 is tall and green, 2 is tall and yellow
The phenotype ratio is 2:2
The genotype ratio is 1:1:1:1
1. Parent 1 is TTgg
2. Parent 2 is TtGg
3. The genotype ratio is 1:1:1:1

Answer: Those questions that can be answered using experimentation procedures and observations can be answered through science and those that cannot be answered by experimentation cannot be answered through science.
Explanation:
1. It cannot be answered through science because right or wrong to use genetic engineering may be dependent on other parameters like ethical basis.
2. This can be answered through science. This can be answered while placing the resistant species to insects and observing the effect.
3. This cannot be answered through science. This can be answered on qualitative comparison which does not require scientific experimentation.
4. This can be answered scientifically by tracing the primitive life forms and using the residues to develop a new organism with the help of biotechnology.
5. This cannot be answered through science. This is because social factors must be looked upon to understand how they are responsible for producing accomplished artists.
6. This can be answered through science by analyzing the fossil record with respect to the strata were they were found beneath the earth.
Albinism is inherited as autosomal recessive trait. The frequency of the disease in the population equals to 1:20 000. Calculate frequency of heterozygotes in population.
Answer:
0.0139- frequency of heterozygotes in the population
Explanation:
Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005
This, q = √q^2 = √0.00005 = 0.007
Since p + q = 1
p = 1 - 0.007 = 0.993
Using the formula: p^2 + 2pq + q^2
Where 2pq represents the frequency of the heterozygotes, thing we have
2 x 0.007 x 0.993
= 0.0139

Some salmon have been genetically modified to grow bigger and mature faster than wild salmon. They are kept in fish facilities. Which statement regarding genetically modified salmon is correct
Salmon that have been genetically engineered have generated debate because of worries about the potential environmental and health effects if they were to escape and interact with native populations.
How is the genetic makeup of salmon altered?Canadian researchers patented genetically altered (GM) salmon after introducing a promoter—the genetic equivalent of a "on-off" switch—from an ocean pout and a gene that controls growth hormones in Pacific Chinook salmon into the genetic makeup of an Atlantic salmon.
Do wild salmon contain genetically engineered fish?All Atlantic salmon, including genetically modified (GM) salmon, is farmed salmon. Because Atlantic salmon is an endangered species, there is no natural fishery.

1. Which two substances have parts of their cycles in which the substance must be "fixed"?
A) nitrogen and water
B) sulfur and oxygen
C) water and phosphorous
Answer:
its carbon and nitrogen
Explanation:
took the quiz
Carbon and nitrogen are two substances that have parts of their cycles in which the substance must be "fixed". Thus, the correct option for this question is D.
What is Cycle?A cycle may be defined as the series of steps that regularly run in a repeated manner to deliver the needs of organisms. Examples include the carbon cycle, the water cycle, etc.
Carbon is found as a solid in all of their isotopes but nitrogen is typically a gas that is present in 78% of the earth's atmosphere.
Option D is missing in the question which is carbon and nitrogen.
Therefore, the correct option for this question is D.

Describe what occurs between water molecules in hydrogen bonding. Draw a diagram, labeling the hydrogen bond.
Answer:
The molecules are attracted to their less negative side.
Explanation:
The Oxygen in the water molecule will share or the hydrogens lone atom leaving the hydrogen with a more positive charge like in the picture I've added. This happens with all water molecules leaving the oxygen with more electrons and ultimately the more negative side. And positive and negative forces attract, so the now "positive" hydrogens will bond with the now "negative" oxygens. They form bonds using polarity, and use a very strong dipole dipole effect.
Which inheritance pattern is more likely to affect males than females?
Answer:
karyotype. A display of the homologous chromosome pairs of a cell arranged by size and shape. hemophilia. -bleeding disorder where the blood fails to clot properly.
Explanation:
If the father has the pattern than more likely the son will get the gene. Same goes for the mother and daughter.
One of the first explanations of evolution was put forth by a French biologist, Jean-Baptiste
Lamarck. He theorized that animals, in responding to different environments, adopted new
habits. Their new habits caused them to use some organs more and some organs less, which
resulted in the strengthening of the former and the weakening of the latter. New characters
thus acquired by organisms over the course of their lives were passed on to the next
generation. His theory proposed this process of use and disuse, repeated over many
generations, was how species evolved.
He was wrong. Why?
Answer:
Traits acquired during an organism's lifetime cannot be passed
Explanation:
The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.
Changes to organisms that are not the level of the gene cannot be passed to the offspring. For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.
Only changes that happen to the genome of an organism (mutation) can be passed to offspring.
What is the relationship between the nucleotides, nucleic acids, and DNA?
Answer:
Explanation:
Nucleotides are building blocks of nucleic acids (DNA and RNA). A nucleic acid contains a chain of nucleotides linked together with covalent bonds to form a sugar-phosphate backbone with protruding nitrogenous bases. For example, DNA contains two such chains spiraling round each other in the famous double helix shape.

Complete the sentence choosing from the following words:
catalyse, denatured, digest, soluble, insoluble, energise, excreted, ingested
Digestion is the process of breaking down large food molecules into smaller molecules that are ________ .
Enzymes help to break down food because they ________
chemical reactions.
If the temperature of an enzyme gets too high, the enzyme is ________ .
Answer:
1. Soluble
2. Catalyze
3. Denatured
Explanation:
1. We eat in order to obtain energy. However, this food is often in a complex state and needs to be broken down into its simplest form. The process of digestion ensures this occurs in living organisms. Digestion is the process of breaking down large food molecules into a much more simpler molecule that can be passed on to the blood stream for absorption by cells. These simpler molecules must be SOLUBLE in water for them to be transported into each cell via the bloodstream.
2. The breaking down of food molecules described above is facilitated by certain proteinous chemical agents called ENZYMES. Enzymes are biological catalysts i.e. they help speeden up the rate of biochemical reactions in living systems. In the case of digestion, specific enzymes chemically acts on specific food molecules. For example, amylase acts on carbohydrates, protease acts on proteins etc.
3. As stated above that enzymes are proteinous, it means they possess the characteristics of proteins. One of those characteristics is the ability to get denatured by increase in temperature. High temperature causes an enzyme to lose its specific 3D shape, affecting its functionality. Hence, the enzyme is said to be DENATURED.
A new development involves a network of plastic tubes being printed within an organ. After the whole organ is printed, these plastic tubes are dissolved, leaving a network of empty tunnels.
Why does the organ need to have the empty tunnels within it?
Answer:
These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.
In addition the empty tunnels serve as the routes for nutrients and oxygen supply for the organ.
In summary the tunnels provided a vascular structure to support the organ
