Leaves are the primary organs of photosynthesis in flowering plants and are responsible for capturing the majority of the sunlight needed for this process.
Leaves are specifically adapted to maximize their exposure to sunlight, with a large surface area and chlorophyll-containing cells that are optimized for absorbing and utilizing light energy.
Within the leaf, the mesophyll cells are the primary sites of photosynthesis. These cells contain chloroplasts, which are the organelles responsible for converting light energy into chemical energy through the process of photosynthesis.
While other parts of the plant, such as stems and flowers, may also contain chlorophyll and carry out photosynthesis to some degree, the leaves are the most efficient and specialized structures for capturing sunlight and converting it into usable energy for the plant.

Prior to darwin, ideas about how organisms came into being were mostly based on ________.
Prior to Darwin, ideas about how organisms came into being were mostly based on Religious beliefs.
Before Darwin, people used to strongly believe that the Bible clearly explained about the origin of all living forms. They were very much convinced by the idea that there was a natural order to things made by God.
However, later when fossils were thoroughly studied around Darwin's time, he used the fossil records to substantiate his theory of evolution. Moreover, Geology also became more predominant as a Science during the same time which influenced Darwin's thoughts about the Earth's surface and how it could change over a period of time.

The intensity of sunlight on Earth is affected by
A.) the mass of Earth
B.) the speed of Earth
C.) the number of rotations of Earth
D.) the curved surface of Earth
Answer:
The correct answer is D.) the curved surface of Earth.
Explanation:
The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.
Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

how could changing one mRNA codon change a protein?
Answer:
the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.
Explanation:
hope that helps.:)
Changing one mRNA codon will change a protein because each protein
have their specific mRNA codons.
The mRNA codon are translated into a single amino acid during polypeptide
formation. Changing one mRNA codon will result in the formation of a
different type of protein.
The mRNA codon comprises of three base pairs and a change in an amino
acid such as Alanine which has a codon of GCA which when replaced by
GAC will form aspartic acid.

When an organism is heterozygous, it has two distinct alleles of the same gene.For instance, pea plants can have either homozygous dominant (red-red) or heterozygous red blooms (red-white).They were homozygous recessive if they have white blooms (white-white).Heterozygous carriers are always present.
What characteristic is heterozygous?When an organism has two identical copies of the same gene, it is said to be homozygous for that trait; when an organism has two different copies of the same gene, it is said to be heterozygous for the that trait.
How can you tell whether a plant is heterozygous?One gene is present in hemizygous plants in just one copy.A single gene is present in two identical copies in homozygous plants.Heterozygous plants have different alleles, or distinct versions of the same gene, rather than two copies of the a single gene.

what would you expect the levels of 2.3-bpg (same as 2,3-dpg) to be in mark's blood compared to normal?
2,3-BPG, also known as 2,3-diphosphoglycerate, is a molecule found in red blood cells and plays an important role in oxygen transport. Normally, 2,3-BPG levels in the blood should be between 1.2-2.3 mM.
If the 2,3-BPG levels in Mark's blood are lower than normal, it could indicate a decrease in oxygen-carrying capacity and a possible decrease in oxygen availability to the tissues. On the other hand, if the levels of 2,3-BPG in Mark's blood are higher than normal, it could indicate an increase in oxygen-carrying capacity and an increase in oxygen availability to the tissues.
In either case, further testing is necessary to make a diagnosis and assess the cause of any abnormal levels. If any abnormalities are found, Mark should seek medical care to address the underlying cause and receive appropriate treatment.

what is the biodiversity score of farmland (maize)?
Answer:
Required Answer:-The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

Explanation:
If the load on the cart was reduced by half (800-grams to 400-grams) but the force being exerted on the cart remained the same then the cart would ultimately move faster than before. More likely at double the speed, this is because there is less force being exerted in the opposite direction due to friction caused by the load of the cart.

D. A form of virus that infects cells.
Answer:
A. strands I'd DNA wrapped around proteins.
Explanation:
DNA is securely packed within the nucleus by chromosomes, which are thread-like structures. Histone proteins offer structural support for DNA by coiling it around them. During cell division, chromosomes assist in the replication and distribution of DNA. Each chromosome has a centromere, which separates the p (short) and q (long) arms. The centromere is found at the constriction point of the chromosome, which may or may not be the center.

What is the effect of paraquat on ATP, NADPH,
and sugar?
Answer:
ATP will increase
NADPH will decrease
Sugar will decrease
Explanation:
Trust, and I just got this answer
The effect of paraquat on ATP, NADPH, and sugar includes the fact that ATP will increase, NADPH will decrease, and sugar will reduce.
Paraquat is also referred to as methyl viologen. It's a toxic chemical which is used as an herbicide for grass and weed control.
Paraquat can cause damage to one's health when it comes into contact with one's mouth or intestines.
It should be noted that biochemical changes that are caused by paraquat in the lungs will lead to rapid and prolonged oxidation of the NADPH. This then leads to the reduction in NADPH as it attempts to detoxify the lipid hydroperoxides. Also, paraquat will lead to an increase in ATP and a reduction in sugar levels too.

Differentiate between osmosis and active transport (4 marks)
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane. Active transport is the movement of a substance against a concentration gradient.
What is Osmosis?Osmosis is the automatic net movement or diffusion of solvent molecules through a selectively-permeable membrane from a part of high water possibility (region of lower solute concentration) to parts of low water potential (region of higher solute concentration), in the order that tends to equalize the solute concentrations on the two sides.
It may also describe a physical process in which any solvent moves across a selectively absorptive membrane (permeable to the solvent, but not the solute) by dividing two explanations of different concentrations. Osmosis can be created to do work. Osmotic pressure is described as the external pressure required to be involved so that there is no net motion of solvent across the membrane. Osmotic pressure is a colligative property, suggesting that the osmotic pressure depends on the molar concentration of the solute though not on its individuality.

how does comparing the skeletons of these animals provide support for the scientific theory of evolution
Comparing the skeletons of different animals provides compelling evidence that supports the scientific theory of evolution. By examining the anatomical structures and bone arrangements of various species.
Scientists can identify patterns that reflect common ancestry and gradual change over time. One way skeletons provide evidence for evolution is through the presence of homologous structures. Homologous structures are similar in form but may serve different functions in different organisms.
For instance, the pentadactyl limb structure, characterized by five digits, is found in a variety of vertebrates, including humans, bats, whales, and birds. This similarity suggests a common ancestor with a limb structure that has been modified for different purposes.

If reproductive isolation is the criterion used to define species, then the process of speciation is equivalent to ____.
If reproductive isolation is the criterion used to define species, then the process of speciation is equivalent to the formation of new species.
Reproductive isolation refers to the inability of individuals from different populations to produce fertile offspring. This occurs when there are barriers preventing gene flow between populations, such as geographic isolation or differences in mating behaviors.
Speciation, on the other hand, is the evolutionary process by which new species arise. It involves the accumulation of genetic changes over time, leading to the development of distinct populations that can no longer interbreed. When reproductive isolation is established, it effectively separates these populations and prevents the exchange of genetic material.
The process of speciation can occur through various mechanisms, including allopatric speciation, sympatric speciation, and parapatric speciation. In each case, reproductive isolation is a crucial step in the formation of new species. Once reproductive isolation is achieved, the populations can continue to diverge genetically, leading to the accumulation of unique traits and adaptations.
In summary, if reproductive isolation is the criterion used to define species, then the process of speciation is equivalent to the formation of new species. It involves the establishment of barriers preventing gene flow between populations, ultimately leading to the development of distinct and reproductively isolated groups.
