Select the organ system which is best described in each sentence.
Which organ system is responsible for transporting nutrients, gases, and hormones through the body?
Which organ system helps waste gases such as carbon dioxide leave the body?
Which organ system includes the brain?
The kidneys and the urethra are part of which body system?
Answers
1. In the organ system, The circulatory system is responsible for providing gases, nutrients, and hormones around the body.
2. The organ system that helps waste gases such as carbon dioxide leave the body is the respiratory system.
3. The organ system that includes the brain is the nervous system.
4. The kidneys and the urethra are part of the urinary system.
1.The circulatory system is the organ system in charge of delivering nutrients, gases, and hormones throughout the body. It consists of the heart, blood vessels, and blood, which work together to transport oxygen, nutrients, hormones, and waste products throughout the body. The heart pumps oxygenated blood to the tissues, delivering nutrients and oxygen, while the blood vessels act as a network of highways to distribute these substances to cells and organs.
2. The respiratory system is the organ system that assists waste gases such as carbon dioxide in leaving the body. The lungs, airways, and respiratory muscle are all part of it. During respiration, oxygen is taken in and carbon dioxide is removed from the body. The lungs exchange gases by inhaling oxygen-rich air and exhaling carbon dioxide.
3. The nervous system is the organ system that contains the brain, as well as the spinal cord and nerves. The brain is the body's command and control Centre, coordinating and regulating many physical activities and processes.
4. The kidneys and the urethra are part of the urinary system. The urinary system is responsible for filtering waste products, excess water, and toxins from the blood, producing urine, and eliminating it from the body. The kidneys filter the blood, removing waste and excess substances, while the urethra is the tube that carries urine from the bladder to the outside of the body during urination.
These organ systems work together to maintain homeostasis and ensure the proper functioning of the human body.

Which of the following represents an in vivo method for cultivating viruses.
a.) HeLa cells
b.) Pure bacterial cell cultures
c.) Embryonated chicken eggs
d.) Lung cell culture
Answers
Embryonated chicken eggs represents an in vivo method for cultivating viruses. (option c)
To cultivate viruses in a living system, an in vivo method is used. Among the options provided, embryonated chicken eggs are the most commonly used method for culturing viruses in a living organism.
HeLa cells: HeLa cells (a) are human cancer cells commonly used in laboratory research, but they are not a living organism suitable for virus cultivation.
Pure bacterial cell cultures: Bacterial cell cultures (b) are often used to study bacteriophages, which are viruses that infect bacteria. However, this method involves culturing viruses in bacterial hosts and does not involve a living organism.
Embryonated chicken eggs: Embryonated chicken eggs (c) are a widely used method for virus cultivation. In this method, viruses are injected into the developing embryo, which provides an environment for viral replication. The embryos provide a controlled and nutrient-rich environment for the viruses to grow and propagate.
Lung cell culture: Lung cell culture (d) involves growing lung cells in a laboratory setting. While this method can be used to study certain viruses, it is an in vitro (outside a living organism) method rather than an in vivo method.
In conclusion, the in vivo method for cultivating viruses among the options provided is embryonated chicken eggs. This method provides a living system in which viruses can replicate and propagate. (option c)

Which argument provides the MOST LIKELY explanation for why populations of sea stars that use sexual reproduction have increased survival than those populations of sea stars that use asexual reproduction?
a.The population that uses sexual reproduction will reproduce at a slower rate allowing for them to identify and adapt to the new environmental conditions.
b.The population that uses sexual reproduction will have increased genetic diversity which will allow the population to adapt to the changing environmental conditions.
c.The population that uses sexual reproduction will reproduce at a faster rate and replace the individuals that do not survive new environmental conditions.
d.The population that uses sexual reproduction will have less genetic diversity which will allow them to adapt to the new conditions more quickly.
Answers
The population that uses sexual reproduction will have increased genetic diversity which will allow the population to adapt to the changing environmental conditions.
What is genetic diversity?Genetic diversity is the term used to describe the amount of variation in a population's genetic material. Genetic diversity is important for the long-term health and survival of a species, as it allows them to adapt to changing environmental conditions. It is also important for the health of a population, as it prevents inbreeding, which can cause genetic defects. Genetic diversity can be measured in a number of ways, including looking at the number of different alleles in a population, the amount of genetic variation in a population, and the amount of variation between individuals within a population. Genetic diversity is influenced by a variety of factors, including mutation, natural selection, and gene flow. Ultimately, genetic diversity is essential for the survival of a species, and it is important to maintain and promote a healthy level of genetic diversity in order to ensure a species’ long-term survival.

Explain what will happen if there are not enough resources to support the individuals in a species.
Answers
Survival of White Rabbits occurs higher as compared to the Survival of Brown Rabbits due to camouflage abilities in that light colored environment.
Why resources are important for organism?If there are not enough resources to support the individuals in a species, then they are unable to increase their population because resources helps in the growth and survival of a species.
Sharp teeth, rough skin, or claws to fight of predators are the adaptations that could affect an individual’s chance of survival because these adaptations prevent them from killing.

Answers
Answer:
No, it is not possible to determine whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper. This is because the root system of a plant is hidden underground and cannot be seen from the surface.

if tyler does not eat a diet that includes essential acids , his cells will not be able to build what?
Answers
If Tyler does not eat a diet that includes essential amino acids, his cells will not be able to build proteins.
Amino acids are the basic building blocks of proteins. There are 20 different types of amino acids, 9 of which are considered essential because they cannot be synthesized by the body and must be obtained from food.
The 9 essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are necessary for the body to synthesize proteins, which are essential for the growth and repair of tissues, the formation of enzymes and hormones, and the maintenance of healthy bones, muscles, and skin. Without sufficient amounts of essential amino acids in the diet, the body is unable to build proteins and can lead to protein deficiency, which can cause symptoms such as fatigue, muscle wasting, and impaired immune function.
Therefore, it is important to eat a diet that includes sources of all 9 essential amino acids to ensure adequate protein synthesis and overall health.
