Answer:
the answer is white and sweet, i just took the quiz
Explanation:
The phenotypic ratio provides information about how many genes are involved in the cross, which is the dominant trait and which is the recessive trait. In the exposed example, white and sweet are the recessive traits.
-------------------------------
By looking at the phenotypic ratio of the progeny, you can tell which trait is the dominant one and which is recessive.
Let us assume two diallelic genes, each coding for one trait.
Let us also say that these genes assort independently -they are not linked-, and they do not interact with each other.
When we are only considering one single gene,
the phenotypic ratio after crossing two heter0zyg0us individuals is 3:1. In these situations, we expect to see 3/4 of individuals expressing the dominant trait, and 1/4 expressing the recessive trait.the phenotypic ratio after crossing a heter0zyg0us individual with an h0m0zyg0us recessive one is 1:1. We expect to see 2/4 of the progeny expressing the dominant trait and 2/4 the recessive trait.When we are only considering two genes simultaneously, we expect to find the following phenotypic ratio 9:3:3:1
9/16 individuals expressing both dominant traits3/16 individuals expressing one dominant trait and one recessive trait1/16 individuals expressing both recessive traits.
Now let us analyze each Ear,
Ear #1 – 3 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are purple and 1/4 is whiteDominant trait: purpleRecessive trait: white
Ear #2 – 3 starchy : 1 sweet
Only the sweetness trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are starchy and 1/4 is sweetDominant trait: starchyRecessive trait: sweetEar #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Both traits are considered. The phenotypic ratio is 9:3:3:1Two dihybrid individuals must be involved in the cross9/16 are purple and starchy, 3/16 are purple and sweet, 3/16 are white and starchy, and 1/16 is white and sweetDominant trait: purple and starchyRecessive trait: white and sweetEar #4 – 1 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 1:1One heter0zyg0us individual and one h0m0zygous recessive individual must be involved in the cross2/4 are purple and 2/4 are whiteDominant trait: PurpleRecessive trait: WhiteThe recessive traits are white color and sweet taste.

When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.
Why do heart cells have different characteristics than skin cells???
Heart cells have different DNA than skin cells.
Heart cells reproduce by mitosis.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Answer:
Heart cells express different genes than skin cells
Explanation:
Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.
Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.
All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and gain maturity.
write down at least 5 examples of dominant, recessive or co dominant alleles and what their crosses would yield
Answer:
If both alleles are dominant, it is called codominance. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant Dominant and Recessive Traits List 1． Widow’s Peak. Also known as mid-digital, hairline is a result of expression of the hairline gene. The gene contains 2 alleles: one for straight hairline, which is recessive and the other for widow’s peak, which is dominant.

How many stages are there in cellular respiration?
Answer: three stages
Explanation:
Answer: There are three stages
Explanation: Cellular respiration occurs in the cells of all living things, both autotrophs and heterotrophs. All of them burn glucose to form ATP. The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport.

O A. High humidity
B. Lower air pressure
C. Low humidity
D. Higher air pressure
High air pressure usually means clear weather because stable air is sinking. The correct option would be D.
High air pressureHigh air pressure usually causes the sky to be clear.
This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.
This is unlike low air pressure. It brings a cloudy sky along with precipitation.

What is equilibrium?
Answer:In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
Explanation:
Answer:
Equilibrium means when the concentrations of reactants and products are in an unchanging ratio. Another way of saying this is that a system is in equilibrium when the forward and reverse reactions occur at equal rates.

Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

2.Consists of three distinct layers, which are thin and collapsible.
3.Peripherally located closer to the skin.
4.Blue in colour.
5.Carry blood towards the heart from the various parts of the body.
