When blood is flowing through a vena cava, which main blood vessel will it flow through next?
A hepatic portal vein
B hepatic vein
C pulmonary artery
D pulmonary vein
Answers
Answer:
C.
Explanation:
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.

Heriberto wanted to compare the gravity on the moon to the gravity on earth which statement below is correct
Answers
This question is incomplete; here is the complete question:
Herberto wanted to compare the gravity on the Moon to the gravity on Earth. Which statement below is correct?
The gravity on Earth is less than the gravity on the Moon.
The gravity on Earth is greater than the gravity on the Moon.
The gravity on Earth is equal to the gravity on the Moon
The gravity on Earth is the same as the gravity on the Moon.
The correct answer is The gravity on Earth is greater than the gravity on the Moon.
Explanation:
One of the factors that most affect the gravity (the force that makes objects move towards the center of a body) of planets like Earth or smaller bodies such as the moon is the mass. Indeed, if the celestial body is more massive or contains more mass the gravity force is stronger. Now, the mass of Earth is higher than the one of the moon. This makes the gravity of the moon weaker. Indeed, the gravity on Earth is 9.8 meters per square second, while the one in the moon is 1.62 metes per second, which is about 1/6th of the gravity on our planet.

4. Why does semen contain fructose?
A. Fructose breaks down to provide energy for the penis.
B. Fructose travels with the sperm to feed the egg before it is fertilized.
C. Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
D. Fructose provides energy for the development of the fertilized egg.
I’ll give brainiest:)
Answers
Answer:
The answer is C
Explanation:
I just got it right on the quiz
Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
Semen contains fructose because it feeds the sperm, enabling them to survive long enough to fertilize an egg. Therefore, the correct answer is option C.
What is fructose?Fructose is a type of sugar that provides energy to the sperm as they travel through the female reproductive tract in search of an egg to fertilize. Sperm have a limited lifespan outside the male body, so it is essential that they are supplied with enough energy to reach and fertilize an egg before they die.
The fructose in semen provides this energy to the sperm, allowing them to survive and swim towards the egg. Once inside the female reproductive tract, the fructose is absorbed by the sperm and used to fuel their movement towards the egg. Without the fructose in semen, the sperm may not have enough energy to reach the egg and fertilize it.

Conclude: An organism that breaks down organic matter into simpler materials (like carbon dioxide) is called a decomposer. Decomposers absorb nutrients from living things or the organic matter they leave behind. They do not need to kill to get their food.
Do your results suggest bears are decomposers? Explain your reasoning.
Answers
Answer:
No, because bears kill to get their food. They eat fish and they kill the fish to get them. If they left the fish carcass, decomposers would eat it. The bear makes the food for the decomposers, but it is not a decomposer itself... Does that make sense?

What might happen at the cellular level of the plant if there was no water available for photosynthesis?
Answers
Answer:
when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.
Explanation:
If there was no water available for photosynthesis, the cellular level of the
plant will be affected negatively in areas such as shrinking of cells and
decrease in photosynthetic activities.
Plants require water to produce food in the process known as
photosynthesis. When there is no water the photosynthesis is slowed down
and the cells begin to shrink.
The shrinking of cells then results to the wilting and yellowing of leaves of the plant.

A: Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
B: The Linnaean system of classification takes into account ancestral relationships between organisms
C: Linnaeus concentrated on the genetic characteristics of organisms to classify them.
D:In phylogenetic classification, the group that organisms are put into is called a taxon.
Answers
Answer:
Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Explanation:
took the test
The correct option is (a) Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Phylogeny classifies species based on evolutionary kinship or evolutionary distance (taxonomy). The degree and type of evolutionary distance between organisms determines their phylogenetic connection. Let's define taxonomy in order to better comprehend this idea.The connection between classification and phylogeny?The study and comparison of traits as well as the comparison of groups of organisms are the foundations of both phylogeny and categorization. However, there is a distinct feedback between character interpretation and inferred phylogeny, which is seen in the weighting of the characters used to construct the classification.
