Answer:

Phytoplankton

Explanation:

Formed by unicellular eukaryote microalgae, phytoplankton is defined as the portion of planktonic organisms capable of photosynthesis, constituting the basis of the food chain in aquatic ecosystems. For this reason, we can say that in an ocean ecosystem, phytoplankton production is necessary to start a food chain.

Phytoplankton are composed of individuals from different taxonomic groups that have some common characteristics: they all have individualized nucleus and complex organelles in their cytoplasm, as well as photosynthetic pigments (chlorophyll a, b, carotenoids). These organisms, predominantly autotrophic, can also ingest particles, being characterized in some cases as myxotrophic.

Vedmedyk [2.9K]

Answer:

hemoglobin will bind more oxygen when the partial pressure is low than when the partial pressure is high.

Explanation:

Binding of hemoglobin to oxygen is regulated by several factors. However, the partial pressure of oxygen is the most important factor that determines how much oxygen will bind to hemoglobin. When the partial pressure of O2 is high, hemoglobin binds with large amounts of O2. On the other hand, when the partial pressure of O2 is low, hemoglobin is only partially saturated.

Therefore, the greater the partial pressure of oxygen, the more O2 will bind to hemoglobin until saturation is reached. This is why a lot of O2 binds to hemoglobin in pulmonary capillaries where the partial pressure of oxygen is high.

grigory [225]

Answer:

The right answer is B. The offspring are genetically distinct ... by sexual reproduction.

Explanation:

Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.

In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).

An algal bloom can have a drastic, and often detrimental, impact on ________ biomes.
omeli [17]

Fish and other aquatic life may have a harder time finding food as a result of algae blooms, and whole populations may move away or even perish as a result.

Thick, green muck produced by harmful algal blooms has an adverse effect on clear water, leisure activities, companies, and property values.

  • The process of eutrophication, which happens when the environment becomes enriched with nutrients, increases the quantity of plant and algae development in estuaries and coastal waters, is what causes harmful algal blooms, dead zones, and fish kills.
  • The excessive growth of algae in water bodies is referred to as eutrophication.
  • Algal blooms are what are known as these phytoplankton masses or blooms.
  • Blue-green algae blooms (also known as cyanobacteria, contaminated water supplies, and hypoxia are some of the known effects of cultural eutrophication.
