Biology
1 answer:
kvv77 [185]2 years ago
7 0

Answer: The pea and lettuce plants are leguminous plants.

Explanation:

The pea and lettuce plants must take nitrogen from the soil which they get after the symbiotic association with the nitrogen fixing bacteria. Nitrate and ammonia are the two components of nitrogen that can be taken from the soil and used as a source of nitrogen. Nitrogen is required for the growth of plant and it is the important component of chlorophyll pigment. Chlorophyll pigment is necessary for the process of photosynthesis in which the chlorophyll pigment traps sunlight energy that is involved in the splitting of molecule of water into hydrogen and oxygen.

An opportunistic predator switches prey, capturing whichever prey species is most abundant. As soon as the prey numbers dwindle
Sunny_sXe [5.5K]

Answer:

The correct answer is keystone predator.

Explanation:

In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.

When two hormones must be present to achieve full expression of an effect, that interaction is called ______________.
Vinvika [58]

Answer:

Synergism

Explanation:

Synergism means cooperation, and is a term of Greek origin (synergy). Synergy is a work or effort to accomplish a certain very complex task, and to be able to succeed in the end. Synergy is the moment when the whole is greater than the sum of its parts.

In physiology, synergism occurs when the effect of two or more combined chemical agents is greater than the sum of individual effects. Concerning hormones, synergism happens when two hormones must be present for the full expression of an effect. That is, two hormones act for a certain purpose.

Example: FSH (follicle stimulating hormone) and estrogen cause oocyte maturation, but this only occurs if neither acts in isolation.

1. Oceanic crust: this crust has a thickness ranging from 5 km to 10 km and comprises of denser rocks such as diabase, gabbro and basalt.

2. Continental crust: this crust has a thickness ranging from 30 km to 60 km and comprises of minerals such as quartz, silicate, feldspar, aluminum and less dense rocks such as granite

An igneous rock has a coarse texture and is dark in color. Also, an igneous rock can be accurately described as being produced from magma and formed at Earth’s surface.
