Approximately 1-2% of the sun's output is available for photosynthesis. This is because photosynthesis can only occur within a specific range of the electromagnetic spectrum, known as the visible light spectrum.
This spectrum ranges from 400 to 700 nanometers, with wavelengths outside of this range either being too energetic or not energetic enough to drive photosynthesis. Additionally, not all visible light is equally effective for photosynthesis.
Chlorophyll, the primary pigment used in photosynthesis, absorbs light most efficiently in the blue and red regions of the spectrum, with green light being the least effective.
Therefore, only a small portion of the sun's total output is within the optimal range for photosynthesis. However, this small percentage is still significant as it fuels the production of almost all of the Earth's organic matter, sustaining life as we know it.

A eukaryote is a type of organism that has a nucleus and other membrane-bound organelles.
Therefore, Prior to any modifications in an eukaryote, a transcribed RNA can be called hnRNA and pre-mRNA.
hnRNA stands for heterogeneous nuclear RNA. It is the initial transcript of a gene that has not yet been processed. hnRNA contains exons and introns, which are later spliced out to form mRNA.pre-mRNA stands for precursor messenger RNA. It is the processed form of hnRNA that has had the introns removed. Pre-mRNA is then exported from the nucleus to the cytoplasm, where it is translated into protein.Learn more about eukaryote here : brainly.com/question/30584795

is biological control effective than chemical control of crop protection?
Answer:
No
Explanation:
There are different ways or methods of protecting crops from pest and disease infestation. Two of those ways as mentioned in this question are the chemical control and biological control. Biological control of crop protection involves the use of natural enemies of crop pests, which happens to be living or biotic organisms while chemical control entails the use of pesticides and herbicides to control crop pests and diseases.
Among these two methods, the chemical control is more effective because it yields instantaneous results and gets rid of pests and diseases faster. However, in terms of sustainability, the biological control method is more eco-friendly. Hence, based on this question, biological is not more effective than chemical control of crop protection.

Imagine animal cells had chloroplasts. Chloroplasts allow plant cells to perform photosynthesis. How do
you think this would change the way animals gain energy?
Answer:
It would change the way they gain energy by the animals not having enough things in the body to get it functioning right.
Explanation:
think of it as gas our cars need gas to run, so do animals and us but our gas is food
If animal cells had chloroplasts, it means animals would be able to gain energy directly from sunlight by being able to manufacture carbohydrates as a food source.
The presence of chloroplast would allow an animal cell to photosynthesize and manufacture foods in the form of carbohydrates.
\(6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2\)
The food can be broken down during respiration in order for the energy to be extracted.
\(C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O\)
This would be in addition to animals' ability to gain energy from external food sources through the same respiration.

what step occurs between glycolysis and the kreb cycle, why is this important?
The step that occurs between glycolysis and the Krebs cycle is called the "link reaction" or "pyruvate oxidation." This step is important because it converts the pyruvate molecules produced during glycolysis into acetyl CoA molecules, which can then enter the Krebs cycle to produce more energy for the cell.
During the link reaction, the pyruvate molecules are transported from the cytosol into the mitochondria. There, they are oxidized by an enzyme called pyruvate dehydrogenase, which removes a carbon atom from each pyruvate molecule to form acetyl CoA and carbon dioxide. The acetyl CoA molecules then enter the Krebs cycle, where they are further broken down to produce ATP, NADH, and FADH2.
The link reaction is important because it allows the cell to extract more energy from the glucose molecules that were initially broken down during glycolysis. Without this step, the cell would not be able to produce as much ATP, which is needed for many cellular processes.
In summary, the link reaction is an important step between glycolysis and the Krebs cycle because it converts pyruvate into acetyl CoA, which can then enter the Krebs cycle to produce more energy for the cell.

How does reproductive isolation and extinction connected?
Answer:
Reproductive isolation is defined as processes that prevent individuals of different populations from mating, survival or producing fertile offspring. Reproductive isolation is critical for driving speciation and maintaining species identity,
Explanation:
isolation is known to contribute to divergent evolution, resulting in unique phenotypes. Oftentimes morphologically distinct populations are found to be interfertile while reproductive isolation is found to exist within nominal morphological species revealing the existence of cryptic species. These disparities can be difficult to predict or explain especially when they do not reflect an inferred history of common ancestry which suggests that environmental factors affect the nature of ecological divergence. A series of laboratory experiments and observational studies were used to address what role biogeographic factors may play in the ecological divergence of Hyalella amphipods. It was found that geographic isolation plays a key role in the evolution of reproductive isolation and divergent morphology and that divergence cannot be explained by molecular genetic variation.

In 2-3 sentences, explain how crossing over and independent assortment in sex cells affect the appearance of the fully developed organism.
Compare how asexual and sexual reproduction affect the genetic variation of a population
By generating genetic variation, crossing over and independent assortment in sex cells influence how the fully grown creature looks.
During meiosis, crossing over occurs when homologous chromosomes exchange genetic material, resulting in new combinations of alleles. Independent assortment occurs when chromosomes line up randomly during meiosis, which can lead to different combinations of maternal and paternal chromosomes in the resulting gametes. These gametes can unite during conception to produce kids with fresh and distinctive genetic combinations, which can lead to a variety of physical traits and attributes.
Contrarily, meiosis and the generation of gametes are not involved in asexual reproduction. Instead, a single parent generates genetically identical offspring using processes like binary fission or budding. Because of this, neither meiosis nor fertilisation can produce genetic variation, and the progeny are identical to their parents. As there is no new genetic material to adjust to changing environmental conditions, this may limit the population's ability to adapt.
