Answer and Explanation:

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes the food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.

When one of the links disappears, it affects the superior links as they will not have their food source. The immediately anterior link will be beneficiated, as it will not be eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link.

In the exposed example, if salmon gets extinct, the krill population will increase because they won´t be eaten by salmon. As the krill population goes up, phytoplankton will decrease, because more krill will be eating these organisms.

As salmon disappears, the cephalopod population will be affected, because salmon was one of its food sources. As cephalopods are also eaten by the puffins, these last animals will also be affected. The decrease in puffins population means that the rats' population will decrease too, as rats feed on the puffin´s eggs of puffins. Finally, foxes will be affected too, because rat´s population went down.

This is only one path affected by the extinction of the salmon. But all the animals in the trophic chain will be affected.

Answer:

Phytoplanktons.

Explanation:

This is the primary producers in this ecosystem.Its  extinction  will affect photosynthesis, and therefore oxygen and carbon availability  for  the survival of other organisms in the ecosystem.

Besides this, it is the primary producers for zooplanktons, sandlance, and krills of the food web.Therefore, its extinction  affects the survival and the population of these consumers.

Consequently, Salmon, puffin, and Cepahlopods which depended on the above three primary consumers fizzled out of the foodweb.

Eventually,rats,kitiwake,,gull auklet  population disappear with consequent reduction in the numbers of Fox.

False, the primary locations for cell division in plants are found in specialized regions called meristems, not in the leaf blade tips.

In plants, cell division primarily occurs in specific regions called meristems. Meristems are localized areas of actively dividing cells that enable plant growth and development. They are found in various parts of the plant, but the primary locations for cell division are not in the leaf blade tips.

The two main types of meristems are the apical meristems and the lateral meristems. Apical meristems are located at the tips of roots and shoots, including the stem and branch tips, while lateral meristems are responsible for the increase in girth or thickness of the plant and are typically found in the vascular cambium and cork cambium.

Cell division in the meristems leads to the production of new cells, which then differentiate and specialize into various types of tissues and organs. Leaf blade tips do not possess meristematic regions responsible for primary cell division.

However, leaf development and growth can occur through cell expansion, rather than cell division, in existing leaf tissues. In conclusion, the primary locations for cell division in plants are in specialized regions called meristems, not in the leaf blade tips.

Answer:

- Kidneys and ureters are organs of the urinary system.

- The pituitary gland and thyroid gland are organs of the endocrine system

- Which organ system removes carbon dioxide from the bloodstream? Respiratory system.

- Skin, hair, and nails are associated with the integumentary system.

Explanation:

The urinary system is a system located below the rib cage that serves to filter blood and generate urine as a waste by-product. This system is composed of two kidneys, two ureters, the bladder, and the urethra. Kidneys and ureters are structures of the urinary system which are required for urine production and urine transport to the bladder. The endocrine system is an organ system composed of many glands: 1-the thymus is located between the lungs; 2-the hypothalamus, pituitary gland, and pineal gland are located in the brain; 3-the thyroid and parathyroid glands are located in the middle portion of the neck; 4-the adrenals glands are located on top of both kidneys, and 5-the pancreas is located behind the stomach. The glands of the endocrine system secrete key hormones which are responsible for regulating different bodily functions. The respiratory system is primarily located at the thorax, it consists of the nose, oropharynx, larynx, trachea, bronchi, bronchioles, and two lungs. This system is responsible for absorbing oxygen (O2) from the air (inhalation) and eliminate carbon dioxide (CO2, exhalation) during respiration. Finally, the integumentary system is located all over the body, it consists of the skin and accessory structures (e.g., hair, nails, specialized glands, and nerves). The integumentary system is responsible for protecting other organ systems from injury and pathogenic infections, although other functions of this system include sensory roles, thermoregulation, and Vitamin D production.

The statement that describes population growth least likely to be a direct result of the population being introduced to a new environment is:

"A yellow starthistle population in California grew rapidly in grasslands where other species of plants with similar niche requirements had declined as a result of cattle grazing and drought."

The yellow starthistle population in California growing rapidly in grasslands where other species of plants had declined due to cattle grazing and drought is the least likely scenario of population growth resulting from the population being introduced to a new environment. In this case, the population growth is a consequence of changes in the existing ecosystem due to human activities (cattle grazing) and environmental factors (drought). It does not involve the introduction of the population into a completely new environment.

On the other hand, the other statements describe population growth that can be directly attributed to the population being introduced to a new environment. The mosquito population in Florida growing due to the increasing prevalence of insecticide resistance, the spread of a fungus-like oomycete causing Sudden Oak Death in US forests, and the exponential growth of the brown marmorated stink bug population in the absence of natural predators all involve the populations encountering new conditions or environments that facilitate their growth and survival.

Therefore, the yellow starthistle population in California stands out as the least likely example of population growth resulting from the population being introduced to a new environment.

Explanation:

The two hormones that are most responsible for urine production are antidiuretic hormone (ADH) and aldosterone.

ADH is released by the pituitary gland and acts on the kidneys to increase water reabsorption, which results in a decrease in urine production. Aldosterone is released by the adrenal glands and also acts on the kidneys, specifically on the distal tubules and collecting ducts, to increase sodium reabsorption and potassium excretion. This results in the retention of water, which also decreases urine production. Together, ADH and aldosterone help regulate the amount of water and electrolytes in the body by controlling the production and elimination of urine.
