In simple diffusion, some molecules can move in and out of the plasma membrane without the use of energy along the concentration gradient. These molecules include carbon dioxide, oxygen, water and others. While in facilitated diffusion, carrier/channel proteins are needed to aid the molecules across the concentration gradient.
Answer:
1. Different locations .
2. Different times of the day
Explanation:
Both C4 plants and the CAM plants are highly adapted to survive in the arid or dry conditions. In arid conditions, the high temperature is measured which could interfere with the metabolism of the plants.
So plants have adapted in various forms like the C4 plant to avoid high temperature by performing the process of photosynthesis in different cells especially the mesophyll cells and the bundle sheath cells.
The CAM plants avoid high temperature by closing stomata during daytime and performing photosynthesis at night time.
Explanation:
yes the 4th one is right so yes the one you have is right
Direct participant observation claim that the researcher be physically present. This can cause the respondents to alter their actions in order to look in the eyes of the researcher.
Unobtrusive measures are measures that don't demand the researcher to intrude in the research context.
So, since the trait is eye color, let's use E to represent the dominant allele (brown) and e to represent the recessive allele (blue).
I've attached a Punnett square, but let me real quick explain how I set it up. We know that both parents are heterozygous, which means that they have one of each allele. So that gave us the two sides. Then I filled in the boxes (I assume you've leaned how to do this, if message me and I can explain it).
Looking at the results we can see that 1/4 of the offspring are EE, 1/2 are Ee, and 1/4 are ee. Since the blue allele (e) is recessive, it'll only be expressed if no dominant brown alleles (E) are present. Therefore, only the ee genotype will exhibit blue eyes. So, 1/4 or 25% of the offspring will have blue eyes.
Hope that helps! If you need clarification or anything feel free to message me :)
