Answer:
In photosynthesis, light gives energy to the electron moving through the electron transport chain. So its C.
Explanation:
In the photosynthesis of plants, the light gives energy to the electrons passing through the electron conveyor chain. This Light energy is then transformed to chemical energy, which creates ATP; an energy storehouse molecule, and NADPH, a decreased electron transport. Moreover, light energy is utilized to elevate protons across a membrane to compose a proton-motive force.

During Earth's early history, microbial life on land contributed to the formation of soil. Soil formation, in turn, led to the evolution of land plants. Which term describes this chain of events?
Answer:
The correct answer is - nitrogen fixation.
Explanation:
In soil formation microbes play an important role as they help in providing important compounds such as nitrogen by the process of nitrogen fixation that is used by the plants.
Nitrogen-fixing organisms mostly bacteria are free-living but some live in a symbiotic relationship with plants such as Azobacter or with other organisms such as Rhizobium.

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.This would happen because
Answer:
moths would begin becoming lighter as the pollution is reduced
Explanation:
The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.
The color of the Moths will become lighter as a result of this due to the effect
pollution has on its color.
Industries and factories make use of fuel and when it is burned in generating
sets and other equipment it produces the compound known as Nitrogen
oxide.
The Nitrogen oxide has a brownish color which goes into the atmosphere
where the moths fly in thereby contact with the gas darkens the color to
shades of brown. A reduction in the discharge of the gas will lead to it
becoming lighter.

D: Cells are found in every living thing
The statement that is true about cells are;
- cells come in different shapes and sizes
- cells are considered the basic structural unit
- cells are found in every living thing
- cells are not limited to only a particular size, they have various size and shapes, this is because each cell perform a specific function and as such, they tend to have a different sizes
- cells are considered the basic structural unit of all living things, both plants, and animals, they both depend on cells to survive
- cells are found in every living thing(plants and animals) they perform vital functions

Explain a wedge and give 3 examples.
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.
The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.
The wedge works on the principle of an inclined plane.
The Door Stop Is an example of one,
A Knife is a very thin wedge because it slices through objects

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.
Answer:
Skull three
Explanation:
the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature
It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.
What is the basic evolutionary changes in the group mentioned ?As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.
It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.
Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.
