An amoeba is a single-celled organism that feeds on algae, plants cells, bacteria. When an amoeba feeds, it first makes contacts

with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba’s membrane, forming a vesicle. The pH in the vesicle is then lowered and the contents are degraded. What type of transport is involved in this process?

The answer is; endocytosis

This is a form of active transport that enable cells to import large particles that cannot pass across the membrane. It is a bulk transport system.  The opposite of endocytosis s exocytosis where the cell expels large particles to the outside of the cell.

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
