Is the role of the liver
Answer:
The main role is to filter blood coming from the digestive tract before it passes through the rest of the body. The liver can also detoxify or remove toxic chemicals like drugs and metabolize them. The liver then creates bile that ends up back in the intestines.

How does science directly affect you? Where will what you have learned lead you next? PLEASE HELP ME RIGHT NOW!!!!!!!
Answer: Literally everywhere. Having an at least basic level of science helps you in day-to-day situations. For example, cooking. Not only is it crucial to understand the chemical and physical processes when cooking, you should also understand the complexity of how these micro and macromolecule exchange processes affect you and your body. Another prime example is your health, or human processes. You might not realize this, but your body is a plethora of complex, interconnected systems and networks that work hard 24/7 to maintain homeostasis (keep you alive). Understanding how our human physiques conduct themselves helps us gain the knowledge to be able to stay alive.
A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases
Answer:
A.Blood volume decreases
Explanation:
Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.
Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.
This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.

Which of the following is the best definition of the term genotype?
A genotype is a feature in the genes. I know this since a pheno is a physical trait while geno meaning gene is a trait in the genes that can't be seen.
The genotype refers to an organism's entire genetic makeup, including all of its inherited genes.
What is a genotype?It represents the underlying genetic information that determines the traits and characteristics an organism will have, such as eye color, height, and susceptibility to certain diseases.
The genotype is influenced by the combination of genes passed down from parents and can also be affected by mutations or changes in the DNA sequence. The genotype serves as the blueprint for an organism's development and can impact its phenotype, or observable traits and characteristics.

Rice is an important food crop in the the world. Growing rice requires large amounts of water because the roots of rice plants must remain under water. Explain how genes could play a role in helping farmers grow rice using less water. 2 sentences, explain they could do (answerrrr ASAP)
Answer:
Rice plants possesses several traits which allow sthem to grow in large amount of water because standing water helps them to produce air channel known as aerenchyma that connects roots with shoots and transport oxygen to submerged tissues. Standing water also help many weed to grow and rice plants also takes nutrients from them as well.
Genes are responsible for the traits that allow rice plants to grow in large amount of water but if the gene of rice plant is genetically modified with new gene which is resistant to drought, that can allow the rice to grow in less water.
The genetically modified rice plant then do not require large amount of water and can grow easily.

Cardiac muscle causes movement in the
Answer:
(look at explanation)
Explanation:
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
Cardiac muscle causes movement in the heart.
What is Cardiac muscle?A cardiac muscle is the type of muscle found only in the heart. It is also called the myocardium.
The cardiac muscles are only located in the heart because they are made up of features that are specialized in pumping blood powerfully and efficiently. These features include:
they are involuntary and intrinsically controlled,they are striated,they are branched and single nucleated.Therefore, cardiac muscle causes movement in the heart.

Explain what is happening to air mass from the sea as it moves up the side of the mountain and down the other side.
Answer:
The orographic effect creates cooler air moving up the windward side of mountains and warmer air moving down the leeward side. Often, as the leeward air plunges down the slope, it warms quite dramatically and rapidly. Such rapid warming and drying of air can produce very high winds known as Chinook or Foehn winds.

"After scanning the green labeled areas and the red labeled areas, when we combine the two images, the spots that show up as yellow correspond to "
Answer:
... areas labeled both red and green.
Explanation:
The spots that show up as yellow correspond to areas labeled both red and green.
__
The effect of combining images will depend on the method used to create the combination. There are many possibilities when combining color images.
When mixing red and green light, yellow light is produced. When mixing red and green pigment, brown pigment is produced. When mixing digital representations of red and green, the effect depends on the individual representations, the method of mixing, and the interpretation of the mixed result.
__
Given the way the question is worded, we assume that yellow is produced by a combination of red and green appearing in the same area of the images. That is, ...
The spots that show up as yellow correspond to areas labeled both red and green.

why is the moon white
Moonlight is no longer thought of as the cause. In the 16th century, moonmilk, a soft white limestone precipitate found in caves, was thought to be caused by the rays of the Moon.
Answer:
The moon is not actually white, it's grey.
Explanation:
What I learned is that what makes it white is the reflection of the sun and the sun makes it glow, that's why it looks white.
And if you focus on the moon when it's not full you'll see the other part of it showing but it looks grey not white, because as I told you it's the suns reflection.

which of the following words best matches this definition: The process in which the best adapted organisms survive and pass on their traits, while those that are NOT well adapted do not survive.
Answer:
Survival of the fittest
Explanation:
According to the Darwin’s theory of survival, a species can survive among its peers only when it is fit enough to adapt to the natural changes and hence remain alive till its reproductive stage in order to produce fertile offspring.
Such species which survive are known as fit species while the remaining unable to cope with changing environment die out at an early stage of life.
