For the f1 generation. 100% of whichever had the dominant allele.
it will change for the f2 generation

7. I believe that the correct answer is D. The number of camouflaged guppies in the population would increase while the number of successful mating decreased. This is because the predators will feed on all visible guppies living behind the camouflaging guppies, thus the number of camouflaged guppies will increase in an effort to keep themselves away from predators and the trait is passed to the off springs so as to be more adaptable to the environment.
8. I think the answer is B. Antlers make male moose more likely to attract a mate and pass on the genes for antlers to newborns. The antlers may also be used; as communication tools, to assert dominance over other males and to fight with others. Additionally when the moose feel threatened they lower their heads and points the antlers at the source of danger as a warning. These adaptable characteristics help them survive, defend themselves from other animals, and also play a vital role in reproduction and thus all the traits are passed to the off springs.
9. I believe the correct answer is B, A. afarensis, A. africanus, H. habilis, H. neanderthalensis. Starting with A. afarensis (smallest brain size) there is a continuous increases in both absolute and relative brain size with every successful period of time. 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. I think the answer is C, Hominids evolved to walk upright on their hind limbs, reducing the need for opposable toes. One of the earliest defining traits in human was bipedalism, the ability to walk upright on two legs which evolved over four million years ago. Others include the ability to make and use tools and large, complex brain and the capacity for language and culture among others.
11. I think the answer is D,the 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 to scientific methods. In addition, scientific evidence relies on data or information, and is therefore important for researchers to guarantee that the collected data 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 scientific report, which is then studies by other scientists to ascertain the validity of the whole evidence.
12. I believe the answer is C, by 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.
The correct answer is (c) determining how to manage global resources for all humanity
The goal of the world resource simulation center is a very large platform to manage global resources in the form that it serves to all humanity. The team there compiles the inventory of resources, analyses and assess the resources to solve the current problem as well as anticipated problem. They take help of the emerging technology to solve the problems more precisely. The technology there helps to examine the in-depth problems associated with resources.
Answer:
there is a possibility that the neuron can fire back at the potential neuron.
Explanation:
At a chemical synapses an action of potential triggers the Presynaptic neuron to the postsynaptic neuron either more or less likely to fire its own action of its potential neuron.
