Hypothesis: Christian formulated a hypothesis that a heavier cart will roll faster down-hill than a lighter one. This is a prediction of what he thinks will happen based on his prior knowledge or observations.

Dependent Variable: The dependent variable in this experiment is the time it takes for the cart to roll down the ramp. This is the variable that Christian is measuring and will be affected by the independent variable.

Therefore, the Independent Variable: The independent variable in this experiment is the weight of the cart. This is the variable that Christian is manipulating, by adding weight to the cart in the form of 1 kg, 2 kg, 3 kg, 4 kg and 5 kg. The independent variable is what Christian is testing to see if it has an effect on the dependent variable.

The average lifespan of polar bear in captivity is around about 20-30 years.

Polar bears live an  normal of 15- 18 times in the wild. still, their life  expectation can vary depending on the health of their  terrain and its vacuity of prey. In  prison, polar bears have been known to live as long as 40 times.   Polar bears have several acclimations that help them survive in their Arctic  surroundings. A thick subcaste of blubber helps them stay warm, while their white fur helps them  mix in with their snowy surroundings. Polar bears have  important swimming  capacities, allowing them to swim up to 60  long hauls in a single day. They're also excellent  nimrods,  suitable to  descry their prey from  long hauls down. In recent times, global climate change has caused a  drop in the polar bear population. As the Arctic  ocean ice melts, polar bears have  lower access to their prey, causing them to starve. This has drastically  docked the  lifetime of  numerous polar bears in the wild. In order to  cover these  creatures, conservation  sweats are being made to  save their  niche and  insure their long- term survival.

Polar bears in the Arctic often live for 18 to 20 years. Polar bears are thought by biologists to live short lives in the wild, mostly because as they age, they find it difficult to hunt seals.

Polar bears live between 32 and 35 years under optimum circumstances, such as those offered in captivity, with one captive example living to be 43 years old. However, due to the difficulty of hunting as they age, they seldom ever live above 25 years in the Arctic. Within wild populations, men are assumed to have a lower annual survival rate than females. This is possibly due to the fact that when male polar bears battle over females, they frequently sustain lethal wounds.

It is the job of the placenta to keep teratogens from reaching the fetus

Teratogens are the environmental substance or drugs or any other substance that can cause congenital disorder in a fetus.They can be taken unintentionally or intentionally.No amount of alcohol and cigarattes are considered safe during pregnancy. Alcohol,cigarettes and drugs like marijuana will act as a teratogen and cause cognitive and even physical disorders in fetus.

Studies have shown that about 4-5% of fetus are exposed to teratogens in the gestation period and leads to miscarriages, stillbirths and disorders.A mother can also be unintentionally exposed to some medications that act as a teratogen. When a teratogen enters the body,kidney filters most of it and releases as urine.It is the job of the placenta to keep the rest of the teratogen from entering the fetus.

The family suffered from a shortage of food because the farmer was unable to produce enough crop yield to feed his larger family.

The two basic reasons for the problem faced by the farmer are likely that the size of his family has increased, requiring more food, and that the yield of his crops has not increased to meet the increased demand.

This problem faced by the farmer can be related to the country as a whole in that a country with a growing population may face food shortages if its agricultural production is not sufficient to meet the increased demand for food.

Therefore, it is important for countries to ensure that their agricultural production is able to keep up with the needs of their populations in order to prevent food shortages. This can be achieved through a variety of means, such as investing in technology and infrastructure to increase crop yields, promoting sustainable farming practices, and ensuring that farmers have access to the resources and support they need to be successful.

Ecosystem distribution is related to altitude; regions at high elevations are cold and therefore Latitude 36° north to 41° north. It also includes information on each location's height, average annual precipitation, and habitat.

Altitude influences biomes in part. More specifically, temperature and precipitation are the primary determinants of biomes, although height may influence both temperature and precipitation. As height climbs, the temperature decreases. This would have an impact on the structure and makeup of our biome.

Plants require carbon dioxide to thrive, and higher altitudes have lower air density and atmospheric pressure, resulting in lower carbon dioxide levels and a slower transpiration rate. Impede transpiration and a lack of carbon dioxide slow photosynthesis and development.

White blood cells, also known as leukocytes, play a crucial role in maintaining homeostasis in organisms by defending the body against pathogens and foreign invaders.

They are an essential part of the immune system and are responsible for identifying and destroying harmful microorganisms, such as bacteria and viruses, as well as abnormal cells, such as cancer cells.

There are several types of white blood cells, each with a specific role in the immune response. Some types of white blood cells, such as neutrophils and monocytes, act as phagocytes and engulf and digest pathogens. Other types, such as lymphocytes, produce antibodies that specifically target and neutralize pathogens.

White blood cells are able to detect and respond to a wide range of pathogens and foreign invaders by recognizing specific molecules on their surface, called antigens. They then mount an appropriate immune response, which can include the production of antibodies, activation of other white blood cells, and the release of chemical signals that recruit other immune cells to the site of infection.

A membrane-enclosed sac with a digestive function is called a food vacuole. It is found in protozoans with one cell, including amoeba, plasmodium, etc. When food is consumed, they act as an intracellular stomach, breaking it down. The meal is broken down by the digestive enzymes in it and then released into the cytoplasm for use.

Phagosome and pinosome fusion with lysosome fusion results in the formation of food vacuoles. Due to their merger with lysosomes, food vacuoles contain hydrolyzing enzymes.
