Life cycle of plasmodium in human host consists of 7-10 days survival, causing infection and eradication after getting treatment.
Explanation:Plasmodium is the malaria parasite that causes malaria in humans. The parasite requires two hosts so the life cycle of the parasite includes vertebrates and insect hosts. The life cycle begins from a blood-feeding insect and then into a human host.
When a blood-feeding insect, say a female Anopheles mosquito, makes contact with a human body, it injects parasites in the form of 'sporozoites' into the body. This makes human the second host. The sporozoites then travel through the blood stream and enter lever where they first begin to multiply asexually. This continues for 7 to 10 days without any evidence of symptoms. Then they begin to multiply in red blood cells and continue until the cell bursts. 'Merozoites' are released after each cell break that continue the cycle of multiplication and infect the other red blood cells. Humans spike fever when parasites break free and enter bloodstream, showing the symptoms of Malaria.

what is a likely consequence of continued human population growth?
Continued human population growth could lead to environmental degradation and scarcity of resources like land and water due to the increasing pace at which the global population is growing.
Explanation:A likely consequence of continued human population growth is the degradation of our natural environment and a potential strain on resources. This is due to an increase in the emission of greenhouse gases, especially from developing countries trying to improve their economic condition. As population continues to grow, the time it takes to add a substantial number of humans to the Earth is becoming shorter. For instance, it took 123 years to add 1 billion humans in 1930, but only 24 years to add two billion people between 1975 and 1999. This vector of growth may eventually exceed the carrying capacity of our planet, leading to repercussions such as a shortage of essential resources like land and water, presenting the threat of overpopulation.
It's worth noting that these scenarios are in part based on the concept of exponential population growth, wherein the population doubles in a fixed period of time. In reality, population growth rates can be slowed by factors such as increased access to family planning, education, and sustainable development methods. Ultimately, the threats posed by overpopulation underscore the need to manage our resources prudently and to curb population growth through effective and socially sensitive policies.

Final answer:
Continued human population growth may lead to environmental degradation, heightened greenhouse gas emissions, food shortages, and socio-political challenges due to resource strain.
Explanation:
A likely consequence of continued human population growth is the change and degradation of the natural environment. As the population expands, there is a higher demand for resources, which can lead to deforestation, loss of biodiversity, and increased emission of greenhouse gases like carbon dioxide (CO₂), accelerating climate change. Countries around the world have made efforts to mitigate these effects by limiting emissions, but global consensus and effective international agreements are challenging to achieve. Additionally, population increase puts a strain on food supplies, potentially leading to widespread food shortages. Rapid population growth, paired with environmental stress, could also precipitate socio-political issues, exacerbate global conflicts, and escalate problems like poverty and disease outbreaks.
Which factor has the opposite effect on the solubility of gas solutes as it does on the solubility of solid solutes?
polarity
surface area
temperature
motion
Answer:
Polarity.
Explanation:
Solubility is defined as the upper limit of solute that can be dissolved in a given amount of solvent at equilibrium. In such an equilibrium, Le Chatelier's principle can be used to explain most of the main factors that affect solubility. Le Châtelier's law dictates that the effect of stress upon a system in chemical equilibrium can be predicted in that the system tends to shift in such a way as to alleviate that stress.
The relationship between the solute and solvent is essential in determining solubility. Strong solute-solvent attractions equate to greater solubility, while weak solute-solvent attractions equate to lesser solubility. In turn, polar solutes tend to dissolve best in polar solvents, while non-polar solutes tend to dissolve best in non-polar solvents. In the case of a polar solute and non-polar solvent (or vice versa), it tends to be insoluble or only soluble to a minuscule degree. A general rule to remember is, "Like dissolves like."

The Answer Is Temperature NOT Polarity

If a man with Menkes disease (XMY) has children with a woman who does not carry the disorder (XX), all daughters will be carriers of the disorder (100% chance), and no sons will be affected because they inherit their father's Y chromosome.
The disorder is usually manifested in males who have only one X chromosome (XY). A female (XX) with one affected X chromosome is typically a carrier but does not show symptoms because the healthy X chromosome compensates for the faulty one. When it comes to the inheritance patterns for sex-linked disorders like Menkes disease:
A man with Menkes disease (XMY) will pass on the Y chromosome to his sons, so they will not inherit the disorder.His daughters will inherit his unaffected X chromosome and will not have the disease; however, they will certainly be carriers if their mother is healthy (XX).Therefore, if a man with Menkes disease has children with a woman who does not carry the disorder (XX), all daughters will be carriers (heterozygous for the condition), and no sons will be affected. In summary, if they have a daughter, there is a 100% chance that she will be a carrier for the disorder.When a skateboarder makes

Density-independent limiting factors that can affect a population include
Answer:
The density- independent limiting factors that can affect a population include food, predation, toxic waste and environmental disasters.
Explanation:
Density independent factors like natural calamities which include volcanic eruptions, hurricane, floods, earthquake, etc are not influenced by population density change. For example, the current rampaging bush fire in Australia has caused a lot of damage to different animal and plant species. Many populations of species have become endangered and others are wiped off.
The quality of nutrients available in an environment affect the growth of organisms in it. The lower the quality of nutrients, the higher is the environmental stress. E.g in Lake Erie, the growth of algae was restricted due to the extensive presence of phosphorus in the water bodies.
Pollution is also a big reason for decrease in the density of populations. E.g Amphibians such as toad, frog are susceptible to pesticides which flow into the water bodies. It reduces their ability to reproduce and inhibits their growth.
When the number of predators in a given area increase, the population of prey decreases. Extensive predation can lead to the extinction of prey species.

According to the endosymbiosis theory, scientists believe that early eukaryotes formed from prokaryotes. Why do scientists believe that
prokaryotes existed earlier than eukaryotes?
Final answer:
Prokaryotes predate eukaryotes according to the endosymbiotic theory which posits that eukaryotic cells evolved from prokaryotic cells forming symbiotic relationships. This theory is supported by the presence of prokaryote-like DNA in organelles like mitochondria and chloroplasts and fossil evidence that suggests prokaryotes were already present on Earth billions of years before eukaryotes evolved.
Explanation:
Scientists believe that prokaryotes existed earlier than eukaryotes based on the endosymbiotic theory, which suggests that eukaryotic cells evolved from a symbiotic relationship between two or more prokaryotic cells. This is further supported by mitochondria and chloroplasts having their own DNA similar to free-living prokaryotes and features such as double membranes and genes that are more closely related to those found in prokaryotes. According to the endosymbiotic theory, these organelles were once independent prokaryotic organisms that became permanent residents within larger host cells, leading to the evolution of eukaryotes. As eukaryotic cells are now known to possess complex internal structures and organelles, which presumably evolved through these endosymbiotic events, it is logical to infer that simpler prokaryotic cells predated them. The first eukaryotic cells are thought to have evolved about 2 billion years ago, much later in Earth's history compared to the ancient lineage of prokaryotes.
a shark and a dolphin have similarly shaped bodies and fins
The similarly shaped bodies and fins of the shark and the dolphin are a result of convergent evolution and development of analogous structures.
Explanation:
The animals can differ a lot in their appearance, or look alike a lot, but very often the looks can be deceiving when it comes to determining their relations. In some cases, some animals differ greatly in their appearance, but they are much more closely related than some organisms that look very similar to one another. A nice example of animals that look alike a lot but are not closely related are the shark and the dolphin.
The shark and the dolphin have their common ancestors hundreds of millions of years ago, thus they are anything but closely related, with the shark being a fish, while the dolphin being a mammal. The resemblance in the appearance though has been a result of a convergent evolution, or rather trying to solve the same problems, in the same environment, in the same or similar manner. Because of it, analogous structures developed, making them look very similar.

There are different vegetative patterns throughout the world. The vegetation that can grow is influenced by the amount of heat received. The differences in heat give rise to _______ zones.
The differences in heat give rise to three different zones, Torrid, Temperature, and Frigid Zone.
Explanation:There are major five types of vegetative patterns in the world these are forest, grassland, Tundra desert and Ice sheet. In these regions, different types of vegetation are grown.
The growth of vegetation depends on the amount of heat received. The difference in heat gives rise to major 3 zones. These zones are:
1. Torrid zone- this zone lies between 0 degrees to 23 half a degree north and south to the equator. The sun shines exactly overhead at the places near the equator and in the tropics. Therefore the equatorial and tropical regions receive maximum insolation.
2. Temperate zone- this zone lies between 23 half a degree to 66 half degrees north and south of the equator. This zone experiences the slanting rays of the sun. Due to the spherical shape of the earth, the amount of insolation received by this region is less.
3. Frigid zone- this zone is located between 66 half degree and 90 degrees north and south to the equator. This zone experiences extremely slanting rays of the sun over a large distance. Hence the amount of insolation received is very less.

24. Cellular respiration releases energy by breaking down ____
Cellular respiration breaks down glucose to release energy, with carbon dioxide produced during the Krebs cycle.
Explanation:Cellular respiration releases energy by breaking down glucose in the presence of oxygen. This complex process involves several stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. The step in the oxidation of pyruvate that produces carbon dioxide is known as the Krebs cycle, also referred to as the citric acid cycle. During this cycle, each molecule of pyruvate (which is derived from glucose) is decarboxylated, releasing carbon dioxide as a byproduct.
The energy originally used to hold these molecules together is harnessed in the generation of ATP, which cells use for energy. In summary, cellular respiration converts the stored energy in glucose into a form that can be used by the cells, producing carbon dioxide and water as waste products.
