A chef uses a kitchen strainer to separate spaghetti noodles from water.
A strainer is like a filter that allows certain items through, but not others. Which of the following cell parts functions similarly to a strainer?
mitochondrion
⊝
cell membrane
⊝
ribosome
⊝
nucleus. HELP PLEASEEE
Answers
Given what we know about biological structures, we can confirm that amongst the options listed, the one that most closely resembles the function of the strainer is the cell membrane.
A cell membrane is a barrier that acts as protection and provides mechanical support to a cell. The cellular membrane of a cell is composed of a bilayer of phospholipids, which contain a hydrophilic head towards the interior and exterior of the cell, and a hydrophobic pole directed towards the center of the membrane.
This design allows the cell membrane to be semi-permeable. What this means is that the cell membrane has the ability to allow the passage of certain substances like water and polar ions, while keeping unwanted substances out, much like the strainer described in the question.

Answers
There is difference in the amount of chlorophyll production for shade adapted and sun adapted leaves.
There are differences in the amount of chlorophyll production for sun-adapted and shade-adapted leaves because there is less number of chlorophyll on sun adapted leaves whereas shade adapted leaves have higher amount of chlorophyll in order to catch maximum amount of sunlight for the process of photosynthesis.
There is large amount of oxygen produced by the sun adapted leaves due to higher rate of photosynthesis as compared to shade adapted leaves so we can conclude that there is difference in the amount of chlorophyll production for shade adapted and sun adapted leaves.

Answers
The example of the heterozygous allele is Yy
An allele is a variant, storing copies of genes that express the traits of an organism.
An allele can either be h0m0zygous or heterozygous in nature.
An h0m0zygous allele occurs when there exists an identical allele at a specific locus which can be h0m0zygous dominant (e.g YY) or h0m0zygous recessive(yy).
A heterozygous allele has two different alleles positioned at a specific locus. It is expressed as Yy.

Look at the number of organisms and the amount of energy in each level of the pyramid. Why do you think there are more organisms and energy available for life in the producer level? Use examples from the diagram to support your explanation.
Answers
The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
What organisms, energy available life in the producer level?Even though it cannot be produced or destroyed, energy is emitted as heat at each level. Only 10% of energy is essentially transferred from one level to the next.
An energy pyramid shows how energy moves through the trophic levels of an ecosystem. Because energy is expended by organisms at each trophic level and then lost, the structure is pyramidal.
Therefore, Energy is lost as metabolic heat when animals from one trophic level are ingested by species from the next level, hence energy diminishes as it goes up the food chain.
