The ecosystem-based fishery management approach views the entire ecosystem as relevant to managing a fishery and allows for the diverse societal uses of fish stocks, including fishing, recreation, tourism, and overall ecosystem health.
The ecosystem-based management of fisheries is an approach, which projects a holistic outlook towards the management of fisheries in such a way that, humans can benefit from in numerous ways like fishing for food or recreation, or for breeding new stocks of fish. All this is done keeping in mind the angle of environment and biodiversity conservation of the area as well. This approach is extremely essential to keep a check on the effects of human intervention in the ecosystem of the fisheries and how to maintain a stable balance between the two without harming the latter.

Explain why the simplest drawing to model the principle of independent assortment requires four chromosomes, but the simplest drawing to model the principle of segregation requires only two chromosomes
Independent assortment involves the independent segregation of the alleles of two separate genes on separate chromosomes.
What is the Principle of independent assortment How is it related to the Principle of segregation?
Understanding the law of segregation is necessary before defining independent assortment. According to the law of segregation, individual gamete cells receive two distinct, independently sorted genes during meiosis. On the other side, the random separation of the maternal and paternal DNA allows for a greater variety of genes.
Independent assortment refers to the independent segregation of two different genes' alleles on two different chromosomes. As a result, to create the simplest model of independent assortment, at least 4 chromosomes must be represented as two homologous pairs. On the other hand, only the two chromosomes of one homologous pair need to be drawn because segregation takes into account the separation of the two copies of a single gene carried on a single type of chromosome.

Plants with higher numbers of stomata on the surfaces of their leaves would likely have higher rates of transpiration when compared to plants with lower numbers of stomata because __________
Plants with higher numbers of stomata on the surfaces of their leaves would likely have higher rates of transpiration when compared to plants with lower numbers of stomata because almost 97 % of water from plants is lost through stomatal transpiration.
What is Transpiration?Transpiration is a process which involves loss of water vapour through the stomata of plants and this loss cools the plant down when the weather is very hot, so the water from the stem and roots moves upwards or is 'pulled' into the leaves.
The water remaining 97–99.5% is lost by transpiration and guttation through the presence of stomata in the leaves. In this process, water evaporates in the atmosphere from plant leaves and other part.
There are different types of transpiration which depends on the organ that performs transpiration

Given what you know about the function of synapsin, what would you expect to find
When the synapsin gene is knocked out there will be fewer vesicles in the reserve pool in knockout animals than in controls.

Synapsins are a family of evolutionarily conserved phosphoproteins seen in all synapses. They are reversibly associated with synaptic vesicles. They are responsible for holding the vesicles in place.
There are different isoforms of synapsins. Both synapsin I and synapsin II are the major isoforms of synapsin and are related to the elongation of axons and the synaptic vesicle fusion kinetics regulation. Synapsin III is involved in neurogenesis and synaptogenesis regulation.

________is when the kidneys produce too much hydrogen or retain too much hydrogen which leads to an increase in carbonic acid production. Or the kidneys excrete too much base
Metabolic acidosis is when the kidneys produce too much hydrogen or retain too much hydrogen which leads to an increase in carbonic acid production. Or the kidneys excrete too much base.
What is metabolic acidosis?The primary function of the kidney is to purge toxins from the blood and convert waste products into urine. Around 160 grams of weight and one to one and a half litres of urine are excreted daily by each kidney.When the kidneys do not properly eliminate acids from the blood into the urine, renal tubular acidosis (RTA) ensues. The result is an excessively high blood acid level, or acidosis. While having some blood acid is natural, having too much acid can cause numerous biological functions to become unbalanced.When there is too much acid in the body's fluids, it is called acidosis.When your kidneys and lungs are unable to maintain a healthy pH level in your body, acidosis results.

INTRODUCTION
The decline in weed seed numbers in arable fields (approx. 95%) over the course of the 20th century is witness to the success of weed control measures (Robinson and Sutherland, 2002). This success in weed control has resulted primarily from the extensive use of herbicides, changes in crop rotations and a range of cultivation methods. However, the sustained use of a range of agro‐chemicals, in recent years, has resulted in an increase in the number of herbicide‐resistant weed species (Powles and Shaner, 2001), a shift in the weed flora of arable fields from one of mixed weeds to one dominated by grass weeds (Barr et al., 1993) and increasing environmental and public health concerns over the use of pesticides (Conway and Pretty, 1991).

Cytotoxic t-cells are able to recognize infected body cells because the infected cells display foreign antigens.
What do cytotoxic killer T cells do?The helper T cell and the cytotoxic T cell are the two main subtypes of T cells. Helper T cells, as their names imply, "assist" other immune system cells, whereas cytotoxic T cells "kill" virally-infected cells and tumors. The TCR cannot directly bind antigen, unlike an antibody.
Killer T cells are also known as "cytotoxic" or "cytolytic" cells because they have unique molecular weapons that allow them to attack and kill other cells that are showing targets they are familiar with, such as a virus-infected cell or even a malignant cell. The processed cancer cell antigen, which is solely presented by MHC-class I, must be recognized by cytotoxic T lymphocytes. Helper T cells binding to a processed antigen on the same dendritic cell as the MHC-class II presenting a processed cancer cell antigen enhances cytotoxic T-cell complete activation.

How do xenoturbellida relate to hemichordates and nonvertebrate chordates?
The deuterostome group's gene arrangement in the mitochondrial genome of Xenoturbella bocki is remarkably close to that of the chordates and hemichordates and hence to the ancestor deuterostome gene order. Inversion and breakpoint studies particularly point to a similarity to the hemichordates.
Previous morphological investigations imply that Xenoturbella could be classified as a bivalve mollusc, a basal bilaterian, a turbellarian flatworm, a sister group to the echinoderms(nonvertebrate), or a hemichordate. Recent genetic analyses that focus mostly on nuclear genes appear to favour the Ambulacraria (echinoderms + hemichordates).

Reason behind this is antidiuretic hormone are synthesized in hypothalamic supra optic nerves .Hence, destruction of supra optic nerve in the hypothalamus will alter the production and secretion of ADH . ADH is stored in posterior pituitary gland and is released into the circulation in response to extracellular fluid changes by the osmoreceptors in the brain.
