Blood flows from the right atrium into the right ventricle through the tricuspid valve. When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium. Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs.

How does the burning of fossil fuels and deforestation contribute to the overall amount of carbon dioxide?
Answer:
Forests store large amounts of carbon. When fossil fuels are burned, carbon from dead and decayed plants, animals and phytoplankton that lived hundreds of millions of years ago (before dinosaurs existed), is released into the atmosphere in the form of carbon dioxide. .

Asbestosis is a condition that affects the
O A. heart
O B. brain
O C. lungs

Answer:
lungs
explanation:
Asbestosis (as-bes-TOE-sis) is a chronic lung disease caused by inhaling asbestos fibers. Prolonged exposure to these fibers can cause lung tissue scarring and shortness of breath. Asbestosis symptoms can range from mild to severe, and usually don't appear until many years after continued exposure
Answer:
C.Asbestosis is long term inflammation and scarring of the lungs due to asbestos fibers. Symptoms may include shortness of breath, cough, wheezing, and chest tightness. Complications may include lung cancer, mesothelioma, and pulmonary heart disease. Asbestosis is caused by breathing in asbestos fibers.

Answer:
I think its D
Explanation:
B. The Sun is farthest south is the sky is true. A is wrong because in the Northern Hemisphere because the northern part of Earth is tilted most toward the sun. C is also wrong because in September and March – when the Sun shines directly on the Equator and the length of day and night is nearly equal not in winter. And D is wrong because South Pole has 24 hours of daylight not darkness.
If two 15N forces are acting on an object in different directions, what is the net force?
N
Answer:
The net force acting on an object is the combination of all of the individual forces acting on it. If two forces act on an object in opposite directions, the net force is the difference between the two forces.

Describe the pathway in a eukaryotic, somatic cell, from DNA to extracellularly secreted protein. Include detailed descriptions of each mechanism, process, location, molecules and potential outcome.
Answer: The pathway involves the transcription and translation processes.
Explanation:
The DNA present in the somatic cells of the eukaryotic organisms undergoes transcription in which the DNA is used as a template to form mRNA. It occurs in nucleus
The mRNA encodes for a amino acid chain for a specific protein in the process of translation. It occurs in cytoplasm and require a cell organelle called ribosome.
The amino acid sequence for different proteins are different.

Karizma is surprising her mother with her favorite red carnations, but the flower shop only had white. So, Karizma places the white carnations in a solution of water and red food coloring. The carnations turned red by the next day. What could be the possible explanation?
A. Phototropism is responsible for pulling the food coloring from the roots to the petals.
B. The roots pulled up the food coloring with the water and it was transported through the phloem to the petals.
C. Gravity assisted the plant in carrying the food coloring to the petals.
D. Thigmotropism is responsible for pulling the food coloring from the roots to the petals.
E. The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Answer:
The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Explanation:
the xylem is one of the transport tissues in plants. It transfers water and nutrient from roots to stems and leaves.

how many trials did it take for half of the virtualium atoms to decay?
Answer:
Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.

Match the mineral categories to their best descriptions
Answer:
Halide minerals - Minerals that contain elements that combine with chlorine, fluorine, bromine, or iodine.
Rust - An example of a common oxide mineral.
Native Element Minerals - Contains atoms of a single element.
Sulfate minerals - Contains the elements sulfur and oxygen.
Explanation:
I just took the test and its correct. Hope you make a good grade!
The minerals categories matched to their best description are :
Halide minerals: Minerals that contain elements that combine with chlorine, fluorine, bromine, or iodine.Rust: An example of a common oxide mineral.Native Element Minerals: Contains atoms of a single element.Sulfate minerals: Contains the elements sulfur and oxygen.What are minerals?A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.
Halide minerals are those that combine with halogens. Rust is a common oxide mineral. Sulfate minerals consist of sulfur and oxygen. Native minerals (originally found) are those that consist of only toms of a single element in pure form.
Therefore, the minerals are matched with their correct description.

types of transpiration
Answer:
Types of Transpiration
There are three different types of transpiration in plants:
Stomatal Transpiration
It is the evaporation of water from the stomata of the plants. Most of the water from the plants is transpired this way. The water near the surface of the leaves changes into vapour and evaporates when the stomata are open.
Lenticular Transpiration
Lenticels are minute openings in the bark of branches and twigs. Evaporation of water from the lenticels of the plants is known as lenticular transpiration.
Lenticels are not present in all the plants. A minimal amount of water is lost through lenticels.
Cuticular Transpiration
It is the evaporation of water from the cuticle of the plants. The cuticle is a waxy covering on the surface of the leaves of the plants. About 5-10% of the water from the leaves is lost through cuticular transpiration. During dry conditions when the stomata are closed, more water is transpired through the cuticles.

Based on California’s experience with Caulerpa, the killer algae, explain why it is important to regulate the pet and aquarium trade.
Answer:
Based on California's experience with Caulerpa, the killer algae, explain why it is important to regulate the pet and aquarium trade. Even species that are kept as pets and in aquariums should be regulated and tracked because their accidental release can have serious negative environmental impacts.
Explanation:
Even species that are kept as pets and in aquariums should be regulated and tracked because their accidental release can have serious negative environmental impacts. Some owners and aquarium keepers intentionally release these species into the wild rather than destroy them, and accidental release is always a risk. Therefore, if a potentially destructive species is going to be kept as a pet or in an aquarium they should be regulated so proper safety precautions can be taken.
