Answer:
The answer you are looking for would be C!
Explanation:
The answer would be C because if you look at the chart you will see that first
- A is incorrect because its opposite
- B is incorrect because U also lived at the same age of Y
- C is correct because Y and U are both in the same rock layer so we can concur that they are from the same age
- D is incorrect because W existed in both rock layers 1 and 2 while x lived only at the 1st layer thus the answer would be C.
Hope this helps, have a wonderful day, and please consider giving me a Brainliest!!! :)
Answer:
Although there is no diagram attached to this question but it can be answered based on the general knowledge of photosynthesis. The answer is:
H2O and light
Explanation:
Photosynthesis is a unique phenomenon that occurs in the Chloroplast of plant cells. It is the process by which plants and other autotrophs obtain their energy source (food) in the presence of sunlight. Photosynthetic process occurs in two distinct stages viz: light dependent reaction and light independent reactions.
The light dependent reaction, as the name implies, is dependent on light to occur. It occurs in the Thylakoid membrane of the Chloroplast, where a photon of light is captured by the Chlorophyll pigment and the energy is used to split molecule of water in a process called PHOTOLYSIS OF WATER. The transfer of electrons across the thylakoid membrane creates a proton pump, which is used to generate ATP and NADPH. NADPH and ATP are electron and energy carriers respectively which enters into the light independent stage in order to synthesize glucose (sugar).
In a nutshell, the inputs of the light dependent stage are LIGHT from the sun, and water (H2O), which provides the proton and electron when split.
Answer:
Graph A: Directional Selection
Graph B: Stabilizing Selection
Graph C: Disruptive Selection
Explanation:
Natural selection as a driving force of evolution cam be defined as a process that a population of organisms undergo in other to become adapted to an environment and survive to produce offspring that are fitter.
Thus, the following graphs represents the three types of natural selection:
Graph A: Directional Selection
Directional selection occurs when one extreme trait is favoured over others by selective pressures.
The graph shows that only one extreme trait is favoured as the population that survives seem to have majorly a particular extreme trait.
Graph B: Stabilizing Selection
In this type of natural selection, neither of the extreme traits are favoured by selective pressures. Therefore, intermediate trait become favoured over the other extreme traits.
Graph C: Disruptive Selection
Selective pressures works against the intermediate trait while both extreme trait at the spectrum are well favoured, which become more established in a population against the intermediate trait.
Answer:
The digestive system!
Explanation:
The digestive system is made up of the digestive tract - a series of hollow organs joined in a long, twisting tube from the mouth to the anus - and other organs that help the body break down and absorb food.
Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine - also called the colon - rectum, and anus.
Answer:
The theory of evolution is supported by instances of direct observation, the existence of homologies and fossils, and certain biogeographical patterns
