Answer:
Red blood cell arrives from the inferior vena cava into right atrium before it passes through the tricuspid valve into right ventricle. It then passes through the pulmonary valve into pulmonary artery before travelling through the lungs and back into the heart, this time the left atrium via the pulmonary vein.
Explanation:
hope this helps
The pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery
The arch of the aorta can be considered as the peak of the ascending aorta.The brachiocephalic trunk refers to the second branch to arise from the aorta. The right common carotid artery arises as a branch of the brachiocephalic trunk of the aortic arch.The facial artery is a branch of the external carotid artery that supplies blood to the muscles and skin of the face.In conclusion, the pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery.

How do vaccines help the immune system fight against pathogens , like viruses and bacteria ?
Answer:
It introduces the body to a virus strand(s) to initiate internal resistance, which is created after a variety of metabolical processes. The idea is that the body would develop immunity to the virus without actually "getting" the virus.
Explanation:
Answer:
When we are exposed to antigens the body sends an immune response to prevent any infection or disease. Vaccines contain the same parts of antigens that can cause diseases, though they are weakened so that they don't actually cause disease, then they trigger the immune system to produce antibodies, which then help to fight against pathogens.
Explanation:
Use the Lotka-Volterra competition model to determine whether the two species of Paramecium will coexist or drive each other to extinction in the scenario below. In these examples, N1 = N2, and K1 = K2 = 50.
Scenario 1: Determine the outcome of the competitive interaction between P. caudatum and P. aurelia if K1 = K2 = 50, α = 0.3, and β = 0.6.
Scenario 2: Determine the outcome of the competitive interaction between P. caudatum and P. aurelia if K1 = K2 = 50, α = 1.5, and β = 0.6.
Scenario 3: Determine the outcome of the competitive interaction between P. caudatum and P. aurelia if K1 = K2 = 50, α = 0.9, and β = 1.2.

Which group of elements on the periodic table forms covalent compounds with other nonmetals
Group 1
Group 2
Group 17
Group 18
grp 17
Explanation:
this should be the new periodic table:) grp 1 and 2 belongs to metal. grp 18 belongs to halogen which have full valence electron thus they are inert/ unreactive. thus the ans is grp 17. grp 17 are halogens which are non metals.
what level of biological organization is illustrated by the image? click the correct box
Answer: Ecosystem
Explanation: This image shows multiple species interacting with their environment: human and rabbit within waterfall and tree.
The level of biological organization that is illustrated by the image is called Ecosystem.
An ecosystem is defined as a self supportiung unit that is made up of a living part (biotic factors) like plants and animals; and non-living part (abiotic factors) like water, soil, air.
In an ecosystem, the biotic community includes population of:
Food producers: That is the autotrophs like the green plants which are seen in the attached diagram.Food consumers : That is the heterotrophs such as animals and human beings.The non-living part of an ecosystem is its abiotic component. this consist of:
Abiotic resources: These are what organisms need to stay alive. they include a source of energy (sunlight as seen in the diagram) and inorganic nutrients ( carbon dioxide, water).Learn more here:

1. Suppose you want to design and build a house. How would you communicate your design plans with the construction crew that would work on the house?
2. Cells build large, complicated molecules, such as proteins. What do you think cells use as their "design plans" for proteins?
Answer:
The correct answer is -
1. blueprints.
2. cells use DNA as their design plans
Explanation:
Blueprint is a representative drawing of an engineering plan that helps in understanding how and where the desired to construct on the house. It helps in communicating what work should be done in the house. It helps in visualizing how the end product should be.
In cells, the design plan is DNA that encodes all the information in a specific nitrogenous base sequence in order to produce specific functions and produce all the proteins

Explanation:
A Father and Mother are both carriers of the autosomal recessive condition known as albinism. They have one child, and a second child two years later. Their first child was not albino. Knowing this, you can say that the probability of the second child having albinism is Note - Albinism is the result of a lack of pigmentation in skin and other cells.
Both the mother and father would have Aa because they are both carriers. i.e., there would be a 50% probability that the child would be albinized (AA) and a 50% chance that the child would be normal (aa).
What is albinism?Albinism refers to a collection of extremely uncommon genetic illnesses that are characterized by the absence of melanin at birth in either an animal or a plant.
People who have albinism either have a significantly diminished amount of melanin or none at all. Both their coloring and their eyesight may be impacted as a result of this. Albinism is characterized by extremely light or very light blonde hair, while some individuals with the condition have brown or ginger hair. The precise color is determined by the amount of melanin that is produced by the body.
