In photosynthesis, electrons are released from water molecules during the light-dependent reactions, also known as the light reactions or the non-cyclic photophosphorylation. The inner thylakoid.
This process occurs in the thylakoid membranes of chloroplasts, where light energy is absorbed by pigments like chlorophyll, and the energy is used to excite electrons in a series of redox reactions.
During the light-dependent reactions, water molecules (H2O) are split or photolyzed by an enzyme called water-splitting complex or photosystem II. This process releases electrons (e-), protons (H+), and oxygen gas (O2) as byproducts. The released electrons are then used in the electron transport chain (ETC) to generate ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are energy-rich molecules used to power the dark reactions or Calvin cycle where carbon dioxide is fixed and sugars are synthesized.

(a) Give these lengths in metres, m, in standard form:
(i) 75 µm (the diameter of a plant cell)
(ii) 750 nm (the diameter of a mitochondrion)
(b) Determine how many orders of magnitude greater a plant cell is than a mitochondrion
:)
A plant cell is two orders of magnitude (or 100 times) greater in size compared to a mitochondrion.
What is Mitochondria?
Mitochondria are small, double-membraned organelles found in the cells of most living organisms, including plants, animals, and humans. They are often referred to as the "powerhouses" of the cell because their main function is to produce energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. Mitochondria are unique among cellular organelles because they contain their own DNA and have their own ribosomes, suggesting that they have evolved from symbiotic bacteria that were engulfed by an ancestral eukaryotic cell billions of years ago. Mitochondria play a crucial role in cellular energy production, metabolism, and other important cellular processes.
(a) Lengths in standard form:
(i) 75 µm = 7.5 × [tex]10^{-5}[/tex] m
(ii) 750 nm = 7.5 × [tex]10^{-7}[/tex]m
(b) To determine how many orders of magnitude greater a plant cell is than a mitochondrion, we can take the ratio of their sizes in standard form and calculate the logarithm base 10 of that ratio:
Log10(7.5 × [tex]10^{-5}[/tex] / 7.5 × [tex]10^{-7}[/tex]

For most of the characteristics of this exercise, both parents are heterozygous. What is the probability that both parents will contribuite a recessive alleles for any given trait?
The probability that both parents will contribute a recessive allele for any given trait is 1/4 or 25%.
In order to determine the probability of both parents contributing a recessive allele for any given trait, we need to consider the probability of each parent passing on a recessive allele. Since both parents are heterozygous, they each carry one dominant and one recessive allele for each trait.
When they produce offspring, each parent randomly passes on one of their two alleles to their offspring.The probability of each parent passing on a recessive allele is 1/2 or 50%. Therefore, the probability of both parents passing on a recessive allele is the product of their individual probabilities, which is 1/2 x 1/2 = 1/4 or 25%.

All of the following supply blood to the lower limbs EXCEPT . -femoral artery -descending aorta -external iliac artery -popliteal.
The blood vessel which doesn't supply blood to lower limb from the given options is Descending aorta.
The descending aorta is a major blood vessel that supplies oxygenated blood to various parts of the body. It originates from the aortic arch and extends downward through the thoracic and abdominal cavities before dividing into the common iliac arteries. Although the descending aorta does contribute to the blood supply for the lower limbs, it does so indirectly by giving rise to the external iliac arteries.
The external iliac artery is the primary blood vessel that supplies blood to the lower limbs. As it passes beneath the inguinal ligament, it becomes the femoral artery. The femoral artery then branches into various arteries that supply blood to the thigh, knee, and lower leg, including the popliteal artery. The popliteal artery supplies blood to the knee joint and muscles in the region, and further divides into the anterior and posterior tibial arteries to provide blood to the lower leg and foot.

How do linked genes react during meiosis and fertilization?
Linked genes are genes that are located close to each other on the same chromosome, and as a result, they tend to be inherited together.
During meiosis, homologous chromosomes pair up and exchange genetic information through a process called crossing over. If linked genes are close together, they are less likely to undergo crossing over and therefore are more likely to be inherited together. This is known as linkage disequilibrium.
During fertilization, the linked genes on the parents' chromosomes are combined to form the offspring's chromosomes. The offspring can inherit the linked genes in the same combination as one of the parents, or a new combination through crossing over during meiosis.
In summary, linked genes tend to stay together during meiosis and are more likely to be inherited together during fertilization, but crossing over can result in new combinations of linked genes.
Linked genes are genes located on the same chromosome, which means they tend to be inherited together during meiosis and fertilization. During meiosis, chromosomes undergo recombination, which can lead to crossing over, where homologous chromosomes exchange genetic material. However, linked genes have a lower probability of crossing over due to their close proximity on the chromosome. As a result, linked genes are more likely to be inherited together during fertilization, leading to specific phenotypic traits being expressed together in offspring.

A cell of an organism is said to be haploid if it only has one pair of chromosomes. All creatures that reproduce sexually are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells are haploid in humans .A haploid cell only contains one pair of chromosomes. Human cells are typically diploid (two copies of each chromosome) as opposed to haploid (one copy of each chromosome). Meiosis, a specific type of cell division where the genetic material of the parent cell is broken up twice, is how the egg and sperm cells are created in humans. As a result, these haploid cells have just one pair of chromosomes. The genetic material is united in the zygote cell that results from sperm fertilizing an egg. In other words, two distinct haploid cells with one set of chromosomes each combine to form a single diploid cell with two sets of chromosomes.
