Macroevolution
<span>Macroevolution occurs within a population. It is True. Macroevolution is a major evolutionary change. It is applied mainly to the evolution of whole taxonomic groups over long periods of time. Unlike microevolution that happens at a smaller degree, macroevolution involves major alterations and modifications. </span>
Answer:
There will be more yellow-colored frogs in the population than red-colored frogs
Explanation:
<u>Available data</u>:
- Strawberry poison dart frogs have different skin colors
- The frogs can be categorized broadly using the colors green, blue, yellow, and red.
- Frogs eaten by snakes
<u>Number of snake attacks Frog color</u>
145 Approx Green
180 Approx Blue
125 Approx Yellow
145 Approx Red
The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.
The attack by snakes is acting as a selective pressure on the frogs´ population. It is an ecological pressure that is modeling the frogs´ phenotype.
Animals that suffer more attacks are the blue ones, followed by green and red frogs. Those that suffer the fewest number of attacks are the yellow individuals.
So natural selection will be acting on this population favoring the alleles that code for yellow color. Genes that express yellow color increase more the frogs´ fitness than genes that code for the other colors. So natural selection increases the frequency of genes coding for yellow color and will decrease the frequency of the other alleles. Probably the less favored will be genes that express blue.
B. Gametophytes produce diploid gamers (the gametes are haploid)
Answer:
1st option and and 3rd one
Explanation:
Explanation:
O2- this is produced by oxidizing water in the light reaction.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). An increase in temperature will increase the rate of photosynthesis.
It happens in several complicated stages, photosynthesis is a rate-limited process, based on several conditions including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reducing agent.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
