Begin with blood flow in the left ventricle, recognizing how the vena cava, aorta, pulmonary artery and veins, right and left atriums, right and left ventricles, arteries, and veins all contribute to blood flow. Oxygenated and deoxygenated blood should also be described in your blood flow description.
Left ventricle, Aortic semilunar valve, Aorta, Arteries, Capillaries, Veins, Inferior vena cava, Right artrium, Tricupsid valve, Right ventricle, Pulmonary semilunar valve, Pulmonary artery, Lungs, Pulmonary veins ( Right & Left ).
Deoxygenated blood is received from the systemic circulation into the right atrium, it is pumped into the right ventricle whereas, The blood that is returned to the right atrium is deoxygenated while the left atrium receives newly oxygenated blood from the lungs through the pulmonary vein.
examples of human activities that can help the environment
Answer:
1 plantation program
2 cleaning surrounding
3 Conserving water
4 Reduce, reuse and recycle ♻️
5 buy products with less packaging
Answer:
There are numerous human activities that can contribute positively to the environment. Here are some examples:
Recycling: Separating waste materials such as paper, plastic, glass, and metal for recycling helps conserve resources, reduce landfill waste, and minimize the need for new raw materials.
Conserving Water: Taking steps to conserve water, such as fixing leaks, using efficient fixtures, and reducing water usage in daily activities like showering and watering plants, helps preserve this precious resource.
Energy Efficiency: Adopting energy-efficient practices like using LED bulbs, turning off lights and appliances when not in use, and properly insulating homes can reduce energy consumption and lower greenhouse gas emissions.
Sustainable Transportation: Opting for eco-friendly transportation methods like walking, cycling, carpooling, or using public transportation instead of relying solely on private vehicles can decrease air pollution and carbon emissions.
Renewable Energy: Supporting and utilizing renewable energy sources like solar power, wind energy, or hydroelectricity helps reduce reliance on fossil fuels and mitigates climate change impacts.
Organic Gardening: Growing your own food using organic gardening methods reduces the use of synthetic pesticides and fertilizers, supports biodiversity, and promotes healthier ecosystems.
Composting: Composting organic waste, such as fruit and vegetable scraps, yard trimmings, and coffee grounds, diverts waste from landfills, enriches soil, and reduces the need for chemical fertilizers.
Planting Trees: Participating in reforestation efforts or planting trees in your community helps combat deforestation, provides habitat for wildlife, and absorbs carbon dioxide from the atmosphere.
Advocacy and Education: Raising awareness about environmental issues and advocating for sustainable practices within your community can create a positive ripple effect and inspire others to take action.
Conserving Resources: Mindful consumption habits like reducing water usage, avoiding single-use plastics, purchasing durable and eco-friendly products, and minimizing food waste can significantly reduce environmental impact.
Remember, even small actions can make a difference when collectively adopted by many individuals.

i need help reasonably defining 10 parts of a cell.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

The science club at Tracy's school is researching how temperature affects fish reproduction. They conducted a study to find out if raising the water temperature would decrease the number of bass eggs that hatched.
They gathered bass eggs from a local lake. Half of the aquariums were kept at room temerpature, and the other half were placed in a sunny window.
What is the independent (test) variable from this experiment?
The size of the lake.
The number of bass eggs that hatch.
The temperature of the water.
The number of aquariums.
Answer:
The temperature of the water.
Explanation:
The independent variable is the thing you are changing in order to observe an outcome. The dependent variable is the outcome (the number of bass eggs that hatch).

How did the Industrial Revolution contribute to global climate change?
A. It led to an increased use of alternative fuels other than fossil fuels.
B. It led to an increased use of coal, oil, and other fossil fuels.
C. It led to the release of chemicals that destroyed the ozone layer.
D. It led to the development of nonrenewable sources of energy. (I think it's B. Please correct me if I'm wrong.)
Answer: You're right its b.
Explanation:
Human activity has rapidly increased the emission of greenhouse gases to the atmosphere. Since the start of the Industrial Revolution, in about 1750, human activities such as burning fossil fuels, including coal and oil, have increased greenhouse gas concentrations in our atmosphere.
Why are tides on Earth higher than normal during spring tides?
-The Moon cancels out the gravitational pull of the Sun on Earth.
-The Sun comes closer to Earth and increases its pull.
-The Moon comes closer to Earth and increases its pull.
-The Sun combines its gravitational force with that of the Moon on Earth.
There is a relationship between breathing and cellular respiration. Breathing involves taking in oxygen and releasing carbon dioxide. How does the oxygen affect the process of cellular respiration?
> Oxygen and ATP combine to produce energy in the form of carbon dioxide.
> Oxygen and glucose combine to produce energy in the form of ATP molecules.
> Oxygen and hydrogen combine to produce energy in the form of ATP molecules.
> Oxygen and carbon dioxide combine to produce energy in the form of ATP molecules.
Answer:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. ... When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.

4. Name three agents of dispersal. In each case, give an example of a plant whose seeds are dispersed by the agents
Answer:
Three agents of dispersal are:
Wind: Some plants have adaptations that allow their seeds to be carried by the wind. Examples include dandelions, which have feathery bristles attached to their seeds that help them float through the air, and maple trees, which have winged seeds called samaras that spin as they fall, allowing them to travel long distances.Animals: Some plants have adaptations that allow their seeds to be dispersed by animals. For example, burrs have hooks or spines that attach to the fur of animals, allowing the seeds to be carried away from the parent plant. An example of a plant that uses this method is burdock. Some fruits, such as berries, are also eaten by animals, which then excrete the seeds in their droppings, allowing them to be dispersed over a wider area. An example of a plant that uses this method is the blackberry.Water: Some plants have adaptations that allow their seeds to be dispersed by water. Examples include coconuts, which have a fibrous husk that can float on water, allowing the seed inside to be carried away by ocean currents, and water lilies, which have seeds that float on the surface of the water and are dispersed by the movement of the water.PLEASE GIVE ME BRAINLIEST!
