Answer:
1. The pathway of a red blood cell from the right ventricle to the brain is:
Right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → artery aorta → arterial vessels → brain .
2. The substance that forms hemoglobin in red blood cells when it passes through the lungs is oxyhemoglobin.
Explanation:
Red blood cells are structures present in the blood, whose function is to transport oxygen (O₂) and carbon dioxide (CO₂). This process requires travel throughout the body, through the blood vessels, and gas exchange at the pulmonary and tissue level.
1. A red blood cell in the right ventricle contains carbon dioxide and must pass to the lungs to be oxygenated. The route it takes from there includes Right ventricle (minor circulation) → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → (joining the major circulation) artery aorta → arterial vessels → brain .
2. The red blood cell or erythrocyte contains a molecule, called hemoglobin, which has an iron core that allows it to bind to O₂ and CO₂ in order to transport them. The affinity for one molecule or another depends on the presence of a certain gas in a certain place.
When the red blood cell passes through the lungs, the concentration of O₂ is higher than CO₂, so the latter is released and O₂ binds to hemoglobin, a conjugation that is called oxyhemoglobin.
A bog is a type of wetland with witch of the following
a. stagnant water

Explanation:
Tony spaces 5 plants apart equally along a line, with the first plant directly in front of a window and the last plant 30 feet away from the window. He gives them equal access to air and water and then monitors the amount of gas each plant releases.Which gas is Tony monitoring and what trend is hemostlikely to see in the data he collects?
A.He is monitoring oxygen. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.B.He is monitoring carbon dioxide. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.C.He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.D.He is monitoring carbon dioxide. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
Answer:
The correct answer would be - C. He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
Explanation:
The release of the oxygen gas in the process of photosynthesis depends on the rate of photosynthesis which depends on various factors such as carbon dioxide, light, and water. In this experiment air (carbon dioxide), water is constant only factors that are changed is light, and an increase in the light energy increase the rate of photosynthesis, and a decrease in the intensity of light depend decreases the rate of photosynthesis.
Thus any change in the light would affect the release of the oxygen gas which is measured through this experiment and gas released should be lowest for the plant farthest away from the windowand highest for the plant closest to the window.
A phagocytic cell has a mutation in a gene for a hydrolytic enzyme that renders the enzyme nonfunctional. What is the most likely effect of the mutation when this phagocytic cell ingests a pathogen?
A. a vacuole will not form
B. the pseudopodia will not be able to surround the pathogen as well
C. pathogen debris will not exit the cell via exocytosis
D. the lysosome will not degrade the pathogen effectively
The impact of the mutation when this phagocytic cell ingests a pathogen when the lysosome will not degrade the pathogen effectively. hence, the option d is correct.
Where the Hydrolytic enzymes should be found?Hydrolytic enzymes are to be found in the cell lysosome. At the time when there is mutation in the hydrolytic enzyme when there is degradation of pathogen in the lysosome that should not be arise because of non functional nature of the hydrolytic enzyme.

Which statements explain the relationship between photosynthesis and cellular respiration?
Answer:
photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food
Explanation:
When a person is cut, the injured tissue initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. if this is a positive feedback mechanismwhich of the following must be part of the process? The heart would slow down to cause a drop in blood pressure. Platelets would release signals to stimulate the production of more platelets. Blood vessels around the cut would constrict to decrease the surface area exposed to the platelets. Chemical signals released would cause a decline in platelet production
Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.

When a red 4 o'clock flower with a white flower, all of the offspring are pink. This type of inheritance is known as:_______ a. codominance b. incomplete dominance c. multiple alleles d. epistatsis
Answer:
b. incomplete dominance
Explanation:
Incomplete dominance is a type of inheritance that does not confirm to Mendel's principles of inheritance i.e it is non-mendelian. Incomplete dominance occurs when an allele of a gene does not completely mask the expression of another allele of the same gene, hence, the two alleles combine to form a heterozygous that is different but intermediate of both parent phenotypes.
This is the case in this question where the red allele (R) of a four o'clock plant is INCOMPLETELY DOMINANT over the white allele (W), hence, they both produce an intermediate pink phenotype (RW), which is a blending of both red and white phenotypes.
Flowering plants are ___.
A.) gymnosperms
B.) laurasians
C.) angiosperms
D.) archaeopteryx
Answer:
C
Explanation:
The flowering plants, also known as Angiospermae, or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma.
List the inputs and outputs of photosynthesis. what parts of the plant are responsible for taking in each of the inputs
Answer:
Inputs: 6CO2 and 6H2O with light energy
output: C6H12O6 and 6O2
Leaves, roots are the major parts of the plant responsible for taking in each of the inputs
Explanation:
The photosynthesis process is the process where carbon dioxide and water are converted into glucose and oxygen in the presence of light. The products of this process act as substrates during cellular respiration. The photosynthesis process can be represented as:
6CO2 + 6H2O ------> C6H12O6 + 6O2
inputs ↑ outputs ↑
Inputs of the reaction are:
1. Carbon dioxide - 6CO2
2. Water - 6H2O
3. light energy from sun
Outputs are:
1. Glucose - C6H1206
2. Oxygen - 6O2
b. The parts of the plant is responsible for taking inputs during photosynthesis is the leaf as it has chloroplast that trapped the light and also helps in getting carbon dioxdie and roots that helps in absorbing water.

Michaelis and Menten studied the enzyme sucrase, which uses sucrose as a substrate. Assume that lactose is a competitive inhibitor of sucrase. This could be demonstrated by appropriate kinetic experiments. Think about the kind of data that would be collected in these experiments.On the axes below, show appropriate double-reciprocal plots that would demonstrate that lactose is a competitive inhibitor. Label the axes, and any intercepts with X and Y axes appropriately.The graph can be used to determine whether or Vmax has changed in the presence of lactose. State what it about the graph that allows this, and whether Vmax has changed in the presence of lactose.
Solution :
In the context, Menten and Michaelis were doing a research. They are studying about the enzyme sucrase that can use sucrose like a substrate.
The intercept on the y-axis gives the value of the Vmax.
As the intercept is same for both the plots, Vmax does not change upon the competitive inhibitor of sucrase.
The graph plotted is provided below.
