The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
What is photosynthesis?Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis.
Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.
After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere. Light-dependent reactions and light-independent reactions are the two main stages of photosynthesis.
Therefore, The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.

In 1960s, eutrophication of the lake was largely addressed by limiting levels of phosphorus.
The largest of the three significant lakes in King County, Lake Washington is also the second-largest natural lake in the state of Washington. In the 1960s, phosphorus concentrations were found to be 70 parts per billion. That was more than enough to support the large growth of algae that discoloured the water and washed up on the shore where it rotted and smelled.
Between 1941 and 1963, the lake received increasing amounts of secondary treated sewage, which led to eutrophication and a decline in the lake's water quality. Eutrophication, often known as the overgrowth of algae and big aquatic plants, is a process that can be brought on by an excess of phosphorus.

True.
The purpose of meiosis is to produce gametes or sex cells. During meiosis, four daughter cells are produced, each of which is haploid (containing half as many chromosomes as the parent cell).
What is Meiosis?
Meiosis contains two distinct cell divisions, which means that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

in correct order, from external to internal, the tissues of the testes include: cremaster muscle tunica vaginalis tunica albuginea septa
The correct order is dartos, tunica vaginalis, tunica albuginea, septa, scrotal cavity, cremaster
small pedunculated bodies may undergo torsion.
The testis lies outside the body cavity in the scrotum where it is maintained at a temperature 2–3°C lower than the body temperature. Failure to descend into the scrotum causes failure of spermatogenesis.
Blood supply
The testis and epididymis are suspended by the spermatic cord containing their arterial blood supply, venous and lymphatic drainage and nerve supply. The testis develops in the L2/L3 vertebral region and drags its vascular, lymphatic and nerve supply from this region to the scrotum.
Testicular and renal pain may mimic each other. Testicular pain hence can radiate to the loin and renal pain often is referred to the scrotum.
The arterial supply is via the testicular artery which is a branch of the abdominal aorta given off just below the level of origin of the renal arteries. The venous drainage is via the pampiniform plexus of veins which become a single testicular vein before terminating in the inferior vena cava on the right side and the left renal vein on the left side.
The lymphatics of the testis and epididymis accompany the blood vessels and drain into the para-aortic lymph nodes. Upper abdomen must therefore be palpated when searching for secondary lymphatic spread from a carcinoma of the testis.
The spermatic cord
The spermatic cord contains the ductus deferens (vas deferens), the testicular artery and the pampiniform plexus of veins. Other structures in the cord are the cremasteric artery, the artery to the vas, nerve to the cremaster, sympathetic nerves and the lymphatics of the testis and epididymis. Because of its passage through the inguinal canal the spermatic cord acquires three coverings, i.e. the external spermatic fascia from the external oblique aponeurosis at the superficial inguinal ring, the cremasteric muscle and fascia from the internal oblique, and the internal spermatic fascia from the transversalis fascia at the deep inguinal ring.
Varicocoele is a condition caused by dilated tortuous pampiniform plexus of veins. The condition, which may be felt as a ‘bag of worms’ while palpating the scrotum, is more commonly present on the left side. As the left testicular veins drain into the left renal veins it may be a sign of a malignant tumour in the left kidney.

once heterochromatin has been established, it will often spread until it encounters which of the following?
Once heterochromatin has been established, it will often spread until it encounters (A) a barrier DNA sequence. So option (A) is the correct answer.
The shape of chromatin in which sections of interphase chromosomes reside is highly dependent on histone tail modifications. When heterochromatin-specific proteins bind to chromosomes, they also tend to modify the tails of adjacent nucleosomes, causing heterochromatin spreading. This diffusion continues until the remodeling protein reaches a DNA sequence that acts as a barrier. Barrier sequences function by having another histone modification that favors the euchromatin conformation. For example, a common barrier DNA sequence modification is to add an acetyl group to lysine 9 of histone H3. This blocks heterochromatin-induced alteration of methylation at the same lysine residue of histone H3.
