Compare the thickness of the right and left ventricles. Which ventricle is thicker the right or left. Explain the difference.
Answer:
When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.
Explanation:
In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.
To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.
The right ventricle is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. The left ventricle has a thicker muscular wall because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater.The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.

What is the function of a seed's endosperm?
a) it divides to become the plant's first root
b) it will become the plant's seed leaves
c) it protects the plant embryo
d) it provides nourishment for the growing plant
Answer:
It's D
Explanation:
I had it on my quiz
Endosperm regulates seed development and facilitates the transmission of maternal nutrients to the embryo. Therefore, option (D) is correct.
What is endosperm?The endosperm is a type of tissue that develops during fertilization and is found inside the seeds of most angiosperm plants. It gives the embryo the nutrients it needs to grow.
Endosperm is produced when the two sperm nuclei that are contained within a pollen grain make their way into the interior of a female gametophyte.
The endosperm contains carbs, protein, and minor amounts of B vitamins and minerals. These components affect our bodies differently: Bran and fiber inhibit starch digestion, preventing blood sugar increases.

1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.
Answer:
2. Sarah
Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.

A biome is a major community of plants and animals living in a specific geographic area and adapted to specific climate conditions. There are five major types of biomes: grassland, forest, desert, aquatic and tundra.
These major biomes can be divided into different categories (e.g., temperate grasslands).The grassland is a biome that has grasses as the dominant vegetation.The temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).In these regions (temperate grasslands) rainfall is insufficient to support trees.The temperate grasslands have four well-defined seasons. i.e., spring, summer, fall (autumn), and winter.Some examples of temperate grasslands include Argentine pampas, Euro Asian steppes and North American prairies.In conclusion, the temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

Explain why reintroducing wolves changed the ecosystem of the park?
WILL GIVE BRAINLIEST
Answer:
After 70 years without wolves, the reintroduction caused unanticipated change in Yellowstone's ecosystem and even its physical geography. ... The healthier bear population then killed more elk, contributing to the cycle the wolves started.
Explanation:
The reintroduction of wolves had several positive effects on the ecosystem.
What are the effects of reintroduction of wolves?The reintroduction of wolves caused a trophic cascade of events in the Yellowstone national park. This resulted in an increase in the population of beavers and also brought back several forms of vegetation.
The killing of wolves in the 1930s resulted in the shifting of predatory pressure on the elk population. But, they were much less active in winter. They browsed on cottonwood plants and aspen.
But now, the predatory pressure came back on wolves. This keeps the elks more active. This also resulted in an increase in vegetation.
The reintroduction of wolves also resulted in the increase in the population of beavers because of the recovery of willow strands reflourished due to the activeness of the elk.
Therefore, the reintroduction of the wolf population greatly impacted the ecosystem of the Yellowstone national park causing a ripple of positive effects.

The equation for photosynthesis can be written as 6CO2 + 6H2O --->
C6H1206 +602. How many oxygen atoms are present in the products of
photosynthesis?
Answer:
six
Explanation:
There are 6 oxygen atoms present in the products of photosynthesis.
What is photosynthesis?Photosynthesis is a process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose (a sugar) and oxygen, using energy from light. This process takes place in chloroplasts within the cells of plants and is essential for life on Earth, as it produces the oxygen that other organisms breathe and the food that supports the food chain.
The glucose produced by photosynthesis is used by the plant as a source of energy or stored for later use. Additionally, the glucose can be converted into other sugars, starches, and cellulose, which are used to build plant tissues.

(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it

(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.
(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.
What is mRNA, rRNA and tRNA?mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.
Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there is no rain? What would be the long-term effects on the plant if the drought were to continue? Explain your answer.
Answer:
I guess it would not grow??
Explanation:
Answer:
When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.
