In the first cross , the expected phenotypes of plants would be bushy/green and straggly/green. In the second cross, the resulting plants are heterozygous for both dwarfism and stem color traits.
In the first cross, the genotype of the bushy, variegated plant is bushy/bushy; green-/green-, while the fully green, straggly plant has the genotype bushy-/bushy-; green/green. Both straggly and variegated traits are recessive, so for the mature plants from this cross, we would expect to observe the phenotypes of bushy/green (homozygous dominant) and straggly/green (heterozygous).
In the second cross, the dwarf plant with a non-purple stem is represented by the genotype dwarf-/dwarf-; non-purple/non-purple, and it is pollinated by the non-dwarf plant with a purple stem, which has the genotype dwarf/dwarf; purple/purple. All the resulting plants observed as non-dwarf size with purple stems indicate that they are heterozygous for both dwarfism and stem color traits.
Therefore, in the second cross, the resulting plants are heterozygous for both traits, indicating that neither dwarfism nor purple stem color is dominant over the other. Both traits show incomplete dominance or codominance, where the heterozygous state exhibits a combination of both traits.

Think about the cells in your lungs. What do they have to be able to do to function?
To line the airways and make mucus, which lubricates and protects the lung
There are numerous different cell types in the lungs. Epithelial cells make up the majority of lung cells. Mucus is produced by epithelial cells that line the airways and coat and shield the lung. Additionally, the lung cells contain blood, nerve, hormone-producing, and structural or supporting cells.
Air enters your lungs when you inhale (breath), and the oxygen in that air travels to your blood. A waste gas called carbon dioxide travels from your blood to your lungs at the same time and is exhaled (breathed out). Gas exchange is a procedure that is vital to life.

Fructose has the formula C6H12O6. How many moles of fructose are there in 0.100 g of fructose?
Considering the definition of molar mass, there are 0.00055 moles of fructose in 0.100 grams of fructose.
Definition of molar massThe molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.
Molar mass of C₆H₁₂O₆In this case, you know the molar mass of the elements is:
C= 12 g/moleH= 1 g/moleO= 16 g/moleSo, the molar mass of the compound C₆H₁₂O₆ is calculated as:
C₆H₁₂O₆= 6×12 g/mole + 12× 1 g/mole + 6× 16 g/mole
Solving:
C₆H₁₂O₆= 180 g/mole
Moles in 0.100 grams of fructoseYou can apply the following rule of three: If by definition of molar mass 180 grams of fructose are contained in 1 mole, 0.100 grams of the compound are contained in how many moles?
[tex]amount of moles= \frac{0.100 gramsx 1 mole}{180 grams}[/tex]
amount of moles= 0.00055 moles

Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of:______
a. protein.
b. glucose.
c. thiamin.
d. riboflavin.
Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of thiamin. The correct answer is c. thiamin..
The neurological condition Wernicke-Korsakoff syndrome is brought on by a lack of vitamin B1 (thiamin). There is no distinction between Korsakoff syndrome and Wernicke encephalopathy. The disease process is the same but at various stages. Both result from brain damage brought on by a deficiency in vitamin B1.
A prevalent deficiency in vitamin B1 is found in patients with alcohol use disorders. Additionally, it frequently affects persons whose bodies do not adequately absorb meals (malabsorption). This can occasionally happen after bariatric surgery or in conjunction with a chronic condition.
Following the disappearance of Wernicke encephalopathy symptoms, Korsakoff syndrome frequently appears. The thalamus and hypothalamus, two lower regions of the brain, are damaged as a result of Wernicke encephalopathy. Memory-related brain regions suffer permanent harm in people with Korsakoff syndrome.

Use a graphic-design program. Using the Insert Image button, insert an image of your food web in the answer space.
The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, caw, rabbit, bird, eagle, mountainlion, and fungi.
Note: Since you did not detailed the organisms you identified in part B, I will define what a trophic web is, and propose an example for you to understand.
What is a trophic web?The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Example.
To make the trophic web, first, you need to define the position of each of the organisms on the web.
Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.
Consumers → heterotroph
⇒ Herbivores → These are the animals that feed on any part of the plants → Let us say we have a caw, a rabbit, and a bird.
⇒ Carnivores → These are the animals that feed on herbivores → Let us say a mountain lion and an eagle.
Decomposer → detritivorous organisms that take energy from dead matter → Fungi
So, our organisms are
plants, caw, rabbit, bird, mountain lion, and eagleFungiPlants directly provide energy to the caw, the rabbit, and the bird.
Plant >> Caw, Rabbit, Bird
The eagle takes energy from the rabbit and the bird.Rabbit and Bird >> Eagle

Certain foraminifera (shellless protozoa) have inconsistent fossil records. The mode of evolution they represent is punctuated equilibrium.
C. punctuated equilibriumWhat punctuated balance?Punctuated equilibrium is an evolutionary theory proposed by North American paleontologists Niles Eldredge and Stephen Jay Gould in 1972, which proposes that most populations of sexually reproducing organisms experience little change over geologic time, and when evolutionary changes in phenotype occur , they occur in a rare and localized way in rapid speciation events called cladogenesis.
With this information, we can conclude that in gradualism mutations occur slowly and gradually so that the appearance of new species occurs in a subtle way. In turn, in punctuated equilibrium, mutation rates are faster and when a new species appears, this event occurs in small jumps.
