The heart is made of muscle and has____chambers,____on each side. The left side contains____blood and the right side contains____blood. The wall of the left ventricle is_____than the wall of the right ventricle because it has to pump blood to the____. Deoxygenated blood from the body enters the heart through the____bringing blood from the top of the body and_____bringing blood from the bottom of the body. From there it passes through the____and through the____into the____. It then flows through the_____to the lungs where it receives oxygen. Oxygenated blood then flows black through the_____into the . It then flows through the____into the_____and out through the_____valve into the_____to the rest of the body. Arteries carry blood_____from the heart while veins carry blood____the heart. The blood in arteries is_____while in veins, the blood is______. One exception to this rule is the____and____.
Answer:
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
Explanation:The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.

Fuel wood is particularly important in many developing countries, which leads to deforestation and overuse of many species trees. Brainstorm two ideas that could help to reduce fuel wood demand, and explain how your ideas would contribute to sustainability of forest resources.
Answer:
My ideas are the following:
1. Maintain clean cardboard and paper discards to be subsequently recycled
2. Reforest the degraded areas using native species with rapid generation times to be subsequently reutilized
Explanation:
In the home it is possible to sort waste materials, including cardboard and paper. These waste products are made of 100 % recyclable materials but only when they are clean. For efficient recycling purposes, it is therefore necessary to maintain clean both materials (for example, by removing plastics or other materials attached to cardboard and paper). Moreover, reforestation can be a sustainable and cost-effective method for protecting native trees in developing countries. In these countries, economic issues may hamper the adoption of reforestation techniques, thereby new areas may be deforested to obtain more fuelwood. To solve this problem, it is possible to reforest vast areas by using native trees that exhibit rapid generation times, which may then be used as an alternative source of sustained raw material.
What's the recipe for success?
Answer:
In my opinion the recipe for success would be determined by your mindset due to the fact that your mind conducts your next move if your mind stays focused on success how could you fail? You have to believe that you can succeed so that if a tasks would come to you, you wouldn't be phased by it because you believe you can already do it without even have done it .
Explanation:
write the one function of each of the following- arteries
Explanation:
Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.

Answer:
which structure does not belong to the pulmonary circuit?
A) left ventricle
B) right atrium
C) right ventricle
D) pulmonary trunk.
please help and define the difference in pulmonary circuit and pulmonary circulation. thanks
Pulmonary trunk does not belong to pulmonary circuit.
What is pulmonary circuit?The circulation provides oxygen and blood to all the parts of the body. The circulation is of two types pulmonary circulation and systemic circulation. When blood moves from heart to other organs it is called systemic circulation.
When blood moves from heart to lungs is called pulmonary circulation. The circulation involves four chambers such as left atrium, left ventricle, right atrium and right ventricle.
Pulmonary trunk is not a part of pulmonary circuit. Blood will flow from auricles to ventricles.
Therefore, Pulmonary trunk does not belong to pulmonary circuit.

What organelles are associated with carbohydrates?
Answer:
The only organelle that is associated with carbohydrate synthesis is the Golgi Apparatus.
Explanation:
Hope this helps!
The organelles which are associated with carbohydrates are mitochondria and the endoplasmic reticulum (SER).
What are Mitochondria?Mitochondria may be defined as the double-membrane bound cell organelle which is found in the cytoplasm of the cell. It was first recognized by Kolliker in muscle cells of insects in 1880.
Mitochondria are known as the "Powerhouse of the cell". This is because the energy required for various activities is released by mitochondria in the form of ATP. This organelle also oxidizes the pyruvic acid and forms energy in the form of ATP.
The smooth endoplasmic reticulum is directly associated with carbohydrate metabolism along with other metabolic processes like the synthesis of lipids, detoxification, etc.
Therefore, mitochondria and the endoplasmic reticulum (SER) are the organelles that are associated with carbohydrates.

The diagram reveals that lipids and proteins are both parts of cell membranes. They have different functions because lipids work to А remove nucleic acids from the cell membrane, and proteins work to hold the cell membrane together. B hold the cell membrane together, and proteins move chemicals across the cell membrane. С stiffen the cell membrane, and proteins create fibers that attach to the ends of the lipids. D move chemicals across the cell membrane, and proteins work to store water in the cell membrane.
Answer:
There is no diagram in this question but the question can still be answered without it.
B. hold the cell membrane together, and proteins move chemicals across the cell membrane
Explanation:
The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms.
The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane.
Besides controlling what goes in and out of the cell, what other two jobs does the cell membrane have?
Answer:
It protects the cell by acting as a barrier.
receives chemical messengers from other cell.
Explanation:
Cell membrane act as a barrier which keep harmful substances to enter the cell and prevents substances to go out of the cell. It also receives chemical messengers and signals from other cell. This cell membrane is responsible for controlling of the flow of substances in and out of the cell. It also helps the cell in cell mobility from one place to another.

Answer:
The correct answer is - Segregation
Explanation:
An organism with the genotype Aa whose half of the reproductive cell or gametes carry A and the rest of the gametes or reproductive cell carries allele a. According to the laws of Mendel, it is the law of Segregation.
In a diploid organism, the genotype of an individual possesses a pair of alleles (50-50 %) for any particular character and is passed one of each to next-generation from each parent.

What type of photoreceptor cell allows us to see gray tones in dim light, and provides our peripheral vision
Answer:
Rods.
Explanation:
There are two types of photoreceptor cells, the cones, and the rods.
The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.
