An overabundance of nutrients—primarily nitrogen and phosphorus—in water starts a process called eutrophication. Algae feed on the nutrients, growing, spreading, and turning the water green. Algae blooms can smell bad, block sunlight, and even release toxins in some cases.

The cardiac muscle also called the myocardium makes up the thickest and middle part of the heart wall and it protects the cell.

The outer layer, known as the epicardium or visceral pericardium, surrounds the cardiac muscle on the exterior. This helps protect it from contact with other organs. The parietal pericardium attached to this outer layer creates a fluid-filled layer that helps lubricate the heart. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles. Muscle cells are composed of a filament system underlying their mechanical properties and internal membrane systems related to the control of contraction.

Genetic crosses in which f1 plants heterozygous for a given allele are crossed to generate a 3:1 phenotypic ratio in the f2 generation are known as monohybrid crosses

A monohybrid mating is a mating between two organisms that have different variations at the locus of interest. Traits examined in monohybrid crosses are determined by two or more variations to a single position in the gene.

In the progeny or F2 generation of monohybrid crosses, Mendel repeatedly observed a phenotypic ratio of three plants with a dominant phenotype and one plant with a recessive phenotype (3:1) F2 generation.

A monohybrid cross is defined as a cross that occurs to offspring in her F1 generation from parents that differ in only one trait.

The loss of epigenetic information as a cause of mammalian aging is called epigenetic drift. Epigenetics refers to the study of changes in the way genes are expressed.

Epigenetic modifications, such as methylation and acetylation, can silence or activate genes. As cells divide and aging , these epigenetic modifications can change, leading to an accumulation of errors in the way genes are expressed. This process is called epigenetic drift. Epigenetic drift is thought to be one of the causes of aging in mammals. As cells age, the epigenetic modifications on their genes become less stable, which can lead to changes in gene expression that contribute to the decline of tissue function. This can lead to an increased risk of diseases associated with aging, such as cancer, heart disease, and neurodegeneration.

The evidence that would have supported the conclusion that the 24-hour rhythms of humans and cyanobacteria reflect convergent evolution is the genetic similarity of the genes that maintain the biological clocks in both organisms.

Convergent evolution is the process by which different organisms independently evolve similar features or adaptations in response to similar environmental pressures or selective pressures.

In the case of circadian rhythms, if scientists found that the genes that regulate the biological clocks in humans and cyanobacteria were similar, it would suggest that both organisms have evolved similar clock mechanisms in response to similar selective pressures, such as the daily cycle of light and dark.

Metabolism, the chemical process that takes place in living organisms. Metabolism comprises two phases: anabolism and catabolism, which occur concurrently and continually inside cells.

Catabolism is the breakdown of organic material, whereas anabolism is the utilization of energy to produce cell components such as proteins and nucleic acids.

The process through which the body converts food and beverages into energy is known as metabolism. Throughout this process, calories from food and liquids combine with oxygen to generate the energy that the body requires.

Anabolism necessitates the use of energy in order to develop and build. Catabolism consumes energy in order to break down. In all living creatures, these metabolic processes collaborate to create energy and repair cells.

Catabolism happens throughout the digestion process. For example, it is the process by which a slice of bread is broken down into basic components that your body can utilise, such as glucose.

Anabolism may be seen in bone formation and mineralization, as well as muscle mass increase.

A single sperm cell contains exactly 0.2 picograms of DNA, 0.8 picogram is the expected nuclear DNA content of a somatic cell. Hence, the correct option is (c).

The expected nuclear DNA content of a somatic cell isolated from this same individual that is arrested in G1 phase would be c. 0.8 picogram. During the normal cell cycle, the DNA content of a somatic cell doubles during the S phase, leading to the replication of all chromosomes, hence each somatic cell will have twice the DNA content of a sperm or egg cell, which only have half the DNA content of a somatic cell because of the process of meiosis. Therefore, if a single sperm cell contains 0.2 picograms of DNA, a somatic cell would have 2*0.2 = 0.4 picograms of DNA in G1 phase and if we double that in S phase the answer is 0.8 picogram.

Also the term "secondary sexual characters" typically refers to physical characteristics that distinguish males from females in sexually reproducing species, such as antlers on male deer or breasts on human females. These characteristics are not related to the reproductive organs themselves (the primary sexual characteristics) and typically develop during adolescence as a result of hormonal changes in the body.

(When exposed to oxygen, human cells do aerobic respiration, which produces acetyl CoA. Human cells may ferment lactic acid in the absence of oxygen, producing lactate.

Lactate: fermentation in human muscle

Ethanol: fermentation in yeast and bacteria

Acetyl CoA: aerobic oxidation

Alcohol fermentation occurs under anaerobic settings and creates ethanol in yeasts and many bacteria.) Under aerobic conditions, pyruvate can diffuse into mitochondria.

The evolutionary links between creatures are shown in a diagram called a phylogenetic tree, which is built based on differences or similarities. The lineages diverge at the branching point, or node, and the length of the each stem shows the total number of cumulative changes. The phylogenetic tree, also known as a taxon, serves as an evolutionary relationship indicator in evolutionary biology. Sister groups are two descendants that split off from the same node.

Cladograms demonstrate shared ancestors across various species as well as how recently their evolutionary paths diverged.

Tropical rainforests have the maximum NPP and biodiversity of almost any terrestrial ecosystem. The physical environment encourages large photosynthetic production and rapid development.

Water, sunshine, and high temperatures are constant in Tropical Rainforests, and there is a dense concentration of plants, resulting in very high GPP and NPP. As a result, increased productivity increases biomass.

Tropical rainforests have the greatest diversity and production. The tropics have more sun energy and resources, which encourages increased output.

Because of the significant quantity of rainfall and warm weather, tropical rainforests may retain a significant species richness of plants.

Net primary production is high in warm, wet biomes such as the tropical rainforest because mild temperatures, ample water, and a year-round growing season drive plant development. Due to severe temperatures and a lack of water, some biomes, such as deserts and tundra, have poor primary production.

The relaxed form is comparable to a regular rubber band. The band will coil into a compact shape resembling a supercoiled plasmid if you hold one side of the band between your thumb and forefinger and roll that side. The band won't continue to twist if you cut it with scissors.
