Answer: False

Explanation:

Weathering is a process of disintegration or breakdown of the rocks into pieces or parts by the action of a physical or chemical agent. Ice wedging or frost wedging is a process of physical weathering which is caused by a physical agent that is water. In region exhibiting the cold temperatures the water present inside the rocks becomes ice. This disturbs the internal structure of the rock. The ice exerts pressure around the surrounding rock structure which leads to the disintegration of the rock by the process of weathering.

On the basis of the above explanation, the given statement is false.

Rickets is a rare disease that causes the bones to become soft and bend. African American infants and children are at higher risk of getting rickets. In adults, severe vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, bone pain, and muscle weakness.

Chyme or chymus is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.

PolarNik [594]

In the deep waters of the ocean, coral reefs are found in abundance. Algae live on these coral reefs, providing nutrition and producing pigments that give color to the corals. The corals offer shelter to the algae. So, they share a association. Climate change has led to increased temperatures and has caused the corals to throw away the algae living inside them. This action causes the corals to be bleached because of a lack of pigment. This change will lead to a decrease in the coral growth, reduced fecundity and can cause death of corals.

7. The correct answer is D, The number of camouflaged guppies in the population would increase while the number of successful mating decreased. The predators will feed on all visible guppies living behind the camouflaging guppies, therefore the number of camouflaged guppies will increase in an effort to keep themselves away from the predators and due to this the off springs will also be more adaptable to the environment by camouflaging.

8. I believe the correct answer is B. Antlers make male moose more likely to attract a mate and pass on the gene for antlers. The antlers can also be used as communication tools, to assert dominance over other males and to fight. In addition when the moose feels threatened it lowers the head and points the antlers at the source of danger as a warning. These adaptable characteristics help the moose to survive, defend itself from other animals and also plays a vital role in reproduction, therefore it is passed to the off springs.

9. The correct answer is B, A. afarensis, A.africanus, H. habilis, H. neanderthalensis. Starting with A. afarensis (smallest brain size) there is a clear increase in both absolute and relative brain size with every successful time period. This is attributed to the activities and tools developed by each stage of evolution. There are many hypothesis attributed to cause a spectacular growth in the brain, e.g. human needed larger brain to develop the precise motor skills, memory, and planning activity required to make tools, develop the greater memory capacity that would make it easier to locate the animals they used to hunt, assimilate and follow the complex rules of their societies.

10. The correct answer is C, Hominids evolved to walk upright on their hind limbs, reducing the need for opposable toes. One of the earliest defining human traits is bipedalism, the ability to walk upright on two legs which evolved over four million years ago. Others include ability to make and use tools and large and complex brain and the capacity for language and culture among others.

11. I believe the answer should be scientific evidence must be found, verified and accepted by the scientific community. A scientific evidence serves to support or counter a scientific theory. the evidence is expected to be empirical evidence and interpretation in accordance with the scientific method. Additionally, scientific evidence relies on data, and it is important for researchers to guarantee that the data they collect is representative of the real situation. It also entails using appropriate methods to collect and analyze data while ensuring that the research is conducted ethically and safely. The data, results and conclusions are then presented in form of a a scientific report, and then this report is studied by other scientists to ascertain the validity of the whole evidence.

12. I think the answer would be finding burial sites of modern H.sapiens in the same region as H. neanderthalensis fossils. This is because Neanderthals are closest to homo sapiens with several defining features of their skulls which include large middle part of the face, angled cheeks, and huge nose for humidifying and warming cold, dry air. They also practiced sophisticated and symbolic behavior unlike other primates before just like homo sapiens which included living in shelters, making sophisticated tools , making and wearing clothes among others
