An excessive, abnormally large scar is a:
O callus.
O corn.
O cicatrix.
O keloid.
A keloid is an excessive, abnormally large scar caused by an overproduction of collagen that exceeds the original wound and may continue to grow even after it has healed.
Explanation:The excessive, abnormally large scar referred to in the question is known as a keloid. Unlike a callus, corn, or cicatrix, which are all common types of scar formations, a keloid forms when the healing process in the skin extends beyond the original wound, resulting in a large raised scar. This is due to an overproduction of collagen, creating a smooth, hard growth. It is important to note that keloids may continue to grow long after the wound has healed.

Science study the life cycle of pathogens in order to find a way to interrupt the course of disease and spread of infection. Scientist study the life cycle of microorganism in order to find a way to cancer and other chronic illness.
Explanation:
The life cycle of microorganisms causing disease in the human is studied to know what agents or antibiotics would stop their activity. There are techniques used such as chemotherapy to kill the invading viruses. The antibiotics are made this way to stop bacterial growth. The agents would be invented to put stop at the particular phase of the life cycle to inhibit growth of the pathogen. It would get convenient to make agents if at immune level it is known what phase of their cycle is reactive.
Studying the life cycle of microorganisms is important in modern medicine to find ways to interrupt the course of disease and prevent the spread of infection.
Explanation:Studying the life cycle of microorganisms is directly related to modern medicine because it helps scientists understand how pathogens cause disease and how to interrupt their course of infection. By studying the life cycle of microorganisms, scientists can find ways to treat chronic illnesses and develop strategies to prevent the spread of diseases. For example, understanding the life cycle of cancer cells can lead to the development of targeted treatments. Therefore, option d, 'Scientists study the life cycle of microorganisms in order to find a way to interrupt the course of disease and the spread of infection,' is the correct answer.
The combination of dominant tree species in Eastern forests will likely change in the future. Some forest types,
including spruce/fir and maple/beech/birch, may shrink significantly or disappear altogether, depending on how
greatly carbon dioxide emissions increase in the future. How would you adapt your behavior to create a different
scenario, one in which the was no substantial change in the tree species over time? Select the tactic that would be of
NO help.
A) Increase your demand for green products and services to reduce your
carbon footprint.
B)Consider alternate energy resources that are not carbon-based: solar or
wind energy
C)Eat locally-produced and organic food; cur meat and dairy consumption.
D)Manage lands for restoration and watershed conservation
Answer:
C) Eat locally-produced and organic food; cur meat and dairy consumption.
Explanation:
Eating organic food will be of no help because humans do not usually use forest trees as food resources. And hence, it will be of no help to stop the carbon dioxide emissions. Hence, option C will be of no help.
The consumption of green products will lead to lesser production of carbon dioxide and hence can be helpful. Using alternate energy sources which are not carbon based will also help to reduce the amount of carbon dioxide. If lands are restored then, these trees will not change over time. Hence, option A, B and D are helpful for no substantial change in the tree species over time.
Answer:
The answer is Not C It is D. I just had the test.
Explanation: Answer C While this is also a positive action, it is not an action that would result in a decrease of carbon emissions. So It is answer D.

The Dominant trait is well, dominant, and therefore over powers the recessive trait most of the time.
Select all that apply.
Which of the following statements are true about hemophilia?
It is an example of an autosomal dominant disorder.
It is an example of an autosomal recessive disorder.
It is an example of a sex-linked disorder.
It involves a protein inside the red blood cells.
It is a disease in which a person has trouble stopping bleeding.
Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.
Explanation:Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.
Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.
Answer:C.) It is an example of a sex-linked disorder. E.) It is a disease in which a person has trouble stopping bleeding.

All organisms, including plants, undergo what essential process?
All organisms, including plants, undergo what essential process?
A. Photosynthesis
B. Cellular Respiration.
C. Sexual reproduction.
Answer:All the living organisms undergo cellular respiration.
Option B
Explanation:Cellular respiration is the process of production of energy from food. This process includes different chemical reactions which squeeze out energy from the food and store that in form of Adenosine Tri Phosphate for the cells to use in future. Thus without cellular respiration, a cell can't survive.
Now the photosynthesis is only restricted within a group of autotrophs which contains chlorophyll and can use Sun's energy to produce glucose from carbon dioxide and water.
Sexual reproduction is also not a feature of many lower organisms like bacteria which divide by means of binary fusion.

Explanation:
Teoría cinética molecular. Las leyes de los gases desarrolladas por Boyle, Charles y Gay-Lussac, que establecieron las principales relaciones entre la presión, el volumen y la temperatura de un gas, están basadas en observaciones empíricas y describen el comportamiento de los gases en términos macroscópicos.
The statement which best describes the Kinetic Theory Model is that When particles in matter gain or lose energy, they change state. Thus, the correct option for this question is C.
What is the kinetic theory model?The kinetic theory model may be defined as a type of theory that significantly states that all matter is composed of particles in motion and that the rate of motion varies directly with the temperature. As the temperature rises, the movement of particles gradually increases.
According to this theory model, the molecular composition of the gas is in terms of a large number of submicroscopic particles which include atoms and molecules. Further, the theory explains that gas pressure arises due to particles colliding with each other and the walls of the container.
Therefore, when particles in matter gain or lose energy, they would definitely change state with respect to the energy that is administered to them. Thus, the correct option for this question is C.

A reflex action is an automatic or involuntary and the rapid response to a particular stimulus, which minimizes any kind of damage to the body from the potentially harmful conditions, such as touching something hot.
What is Reflex action?A reflex, or reflex action, is an involuntary, unplanned sequence or action and is nearly instantaneous response to a specific stimulus. Reflexes are found to be of varying levels of complexity in different organisms with a different type of nervous system. A reflex action occurs by the neural pathways in the nervous system called the reflex arcs.

A reflex action is an involuntary response to a stimulus, exemplified by jеrking the hand away from a hot surface, and occurs via a reflex arc in the nervous system.
The concept of reflex action is fundamental in biology when discussing the nervous system and its responses to stimuli. A reflex action is an involuntary and nearly instantaneous movement that occurs in response to a stimulus. Unlike voluntary actions, which are under the conscious control of the mind, reflex actions happen automatically, without the need for conscious thought. An example of a reflex action can be the jеrking away of the hand from a hot surface. This action is because the external stimulus (the heat from the hot surface) starts impulses in neurons at the body's surface, prompting an immediate response.
Reflex actions are carried out through a reflex arc, consisting of sensory neurons, interneurons, and motor neurons. When a stimulus is strong enough, it triggers sensory neurons, which pass the information via interneurons to motor neurons, resulting in a reflex movement. This process happens very rapidly and does not involve the brain.

Cypris are the members of kingdom Animalia which are multicellular crustaceans. These organisms are both marine and fresh water, but most of them are fresh water pond dwellers. They are microscopic, which needs to be seen through microscope at 40x for proper visualization.
Cypris are heterotrophs which live in the debris below the water bodies and collect their food from them only. They are covered by 2 shells, and a pair of antennae and limbs project out of the body. They are easily eaten by hydra and small fishes as delicious food.
Which describes a population depending on an abiotic factor?
Answer:
Hello!
I'm assuming the options are:
A) A bean plant does not grow well because it is planted where there are many weedy plants.
B) Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.
C) Squirrels eat eggs from a bird's nest.
D) A hawk preys on a mouse.
The answer is B) Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.
Explanation:
An abiotic factor is a non-living factor of an ecosystem that influences the biotic factors and the population inhabiting that ecosystem.Option A describes competition between two plants. This is an example of a relationship between two biotic factors (bean plant and weeds)C again describes the food relationship between two biotic factors (squirrel and bird's eggs).D is an example of predator-prey relationship which is also an example of two biotic factors influencing each other. B describes how coral reefs (biotic factor) utilizes sunlight (abiotic factor) to produce food and and oxygen through photosynthesis.Abiotic factors such as sunlight, rainfall, and temperature affect populations. Organisms have a range of tolerance for abiotic factors, and some species act as indicator species for specific factors.
Explanation:Abiotic factors are the physical and chemical characteristics of the environment that affect populations. For example, the amount of sunlight, rainfall, available nutrients, oxygen levels, and temperature are all abiotic factors. These factors determine the success of populations and can influence the types of organisms that can live in a particular area. For instance, the amount of annual rainfall can determine whether a region is a grassland or forest, which in turn affects the types of animals living there.
Abiotic limiting factors can have a range of tolerance for a population. A species may have a narrow tolerance range for a specific abiotic factor. For instance, a freshwater fish species may have a narrow tolerance range for dissolved oxygen in the water. If the dissolved oxygen level decreases due to eutrophication, the species will die. This fish species can act as an indicator species, as its presence or absence indicates the dissolved oxygen content of the lake.
