Answer: C, A cool windpane
Answer:
a. This is actually a case of frequency-dependent selection. With too many cheaters in a population, the fruiting body's stalk is not built well, and all individuals have lower fitness.
Explanation:
Frequency dependent selection is a process in evolution whereby the
a gene, genotype or phenotype varies depend on the percentage of that gene, genotype or phenotype that is present in the population.
There are two types of frequency dependent selection:
a. Positive frequency dependent selection.
b. Negative frequency dependent selection.
Answer:
Heart is a muscle with 4 chambers while lungs is an organ and exists in pair
Explanation:
Heart is a form of muscle which has 4 chambers namely The right ventricle, the left ventricle, the left atrium, and the right atrium responsible for pumping blood while the lung are organs responsible for respiration or breathing. They have tiny sacs called alveoli and are found in pair.
The phenomenon in which some individuals with a particular genotype fail to display the corresponding phenotype is called incomplete penetrance.
<u>Explanation:</u>
Penetrance is a concept in which a certain population who has a particular changed gene sequences that yield a genetic disorder. In such cases there is a particular population who does not exhibit the phenotypic changes that corresponds to their genotypic changes such a phenomenon is termed as incomplete penetrance for example not all people who have a mutation in the BRACA 1 gene have breast cancer.
Well, the cell membrane is full of a bunch of little holes. Sort of like a coffee filter.
What does a coffee filter do? Well, you put the coffee in it and run water through it. Then what?
The water is small enough to pass through the filter and bring some of the coffee with it. But the coffee grains are too big to pass through the filter. If we really wanted the coffee grains to get through the filter, we could force them through. Do you want chunks in your coffee? Eww.
Now the cell membrane is the same way, the little things (water, carbon dioxide, oxygen, sugar) are all small enough to fit through the tiny holes in the cell membrane. This is called, "Passive Transport". Because the things can passively float their way in and out of the cell.
Now some other things are too big to fit through, so to make them fit, the cell has to use energy to open itself a little bit more to let them in. This is called, "Active Transport". Because the cell needs to be active and use energy to let those things in.
<span>Now Osmosis is the transfer of water and salts (basically) throughout the cell.
Both Salt and Water are small enough to fit through the Cell Membrane using "Passive Transport".
I've posted this same response earlier, and it is my writing.</span>
