The menstrual<span> cycle </span>occurs<span> due to the rise and fall of hormones</span>
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
<span>AUTOTROPH 1. an organism that can make its own food
Plants like algae are autotrophs. They produce their own food with the use of light, carbon dioxide, water, and other chemicals that are vital in their food producing activity. Aside from plants, there are autotroph organisms. An example of this is phytoplanktons.
CALVIN CYCLE 2. the dark reaction process of photosynthesis that uses carbon dioxide for the synthesis of carbohydrates
The Calvin Cycle has three phases. These are 1) carbon fixation, 2) reduction reactions, and 3) RuBP regeneration.
This cycle occurs in the stroma of the chloroplast and it converts carbon dioxide and other chemical compounds into glucose.
CAROTENOID PIGMENT 3. a pigment ranging in color from yellow to red; helpful in capturing the Sun's light energy for use in photosynthesis
Carotenoid is a plant pigment. It produces yellow, orange, and red colors of many fruits and vegetables. Carotenoid pigment is identified as a class of phytonutrients that benefits human health. People who consumes carotenoid rich fruits and vegetables enjoys the antioxidant property of the food as well as the Vitamin A that some carotenoid convert into.
CHLOROPHYLL 4. a green pigment in plants that serves to trap the Sun's energy for photosynthesis
Chlorophyll is the combination of two Greek words "chloros" and "phyllon" which means green and leaf respectively. This pigment also contributes to human wellness as consumption of plants rich in chlorophyll are proven to be very healthy. These health benefits are 1) helps fight cancer, 2) improves liver detoxification, 3) speeds up the healing of wounds, 4) improves digestion and helps control weight, and 5) protects skin from skin virus like cold sores.
CHLOROPLAST 5. the tiny body that contains chlorophyll; part of the cell in which photosynthesis takes place
Chloroplast is a type of plastid that can be distinguished from other plastids due to its green color. Chloroplast is the only plastid that contains chlorophylls a and b, thus its green color.
PHOTOSYNTHESIS 6. a process that involves the use of carbon dioxide and water in the production of glucose and oxygen using the Sun's energy
RADIATION 7. transfer of heat or energy through rays of various wavelengths
</span><span>Radiation is defined as energy travelling through space. Sunshine or sunlight is an example of radiation. Its ultra violet rays radiates heat on the earths' surface which in turn helps our autotrophs undergo photosynthesis.

A) a common ancestor
Homologous structures are structures that are similar in related organisms. There is a basic pattern of bones which can be inherited from a common ancestor
