Answer:

definition with benefit is given below of

1st. gravitropism

2nd. phototropism

3rd. thigmotropism

4th. photoperiod

Explanation:

1st is gravitropism

gravitropism is process in which plant grow in the direction that gravity act

It is also called geotropism

and

Gravitropism is important for plants because it directs the roots to grow in the downward direction that is important for obtaining nutrients

2nd is phototropism

phototropism is the process in which plant growth directed by the light

and

we know plants need light to carry out photosynthesis

so Phototropism direct the growth of the stem and branch toward sunlight

3rd is thigmotropism

thigmotropism is the directional change in growth of plant in response to a touch stimulus

and

thigmotropism is especially important for climbing plant that is use support to climb up

4th is photoperiod

photoperiod is the physiological change in organism in the response to length of the day and night

and

it play important role to determining the physiological developmental process in the plant such as budding and tuberization

Ecosystems include food webs that show predation and prey interactions among organisms. But ecosystems have many more relationsh

AnnZ [28]

Answer:

Explanation:

Food webs describe the relationships — links or connections — among species in an ecosystem, but the relationships vary in their importance to energy flow and dynamics of species populations. Some trophic relationships are more important than others in dictating how energy flows through ecosystems. Some connections are more influential on species population change. Based on different ways in which species influence one another, Robert Paine proposed three types of food webs based on the species of a rocky intertidal zone on the coast of Washington (Ricklefs 2008, Figure 2). Connectedness webs (or topological food webs) emphasize feeding relationships among species, portrayed as links in a food web (Paine 1980). Energy flow webs quantify energy flow from one species to another. Thickness of an arrow reflects the strength of the relationship. Functional webs (or interaction food webs) represent the importance of each species in maintaining the integrity of a community and reflect influence on the growth rate of other species' populations. As shown in Figure 2, limpets Acmaea pelta and A. mitra in the community consume considerable food energy (energy flow web), but removal of these consumers has no detectable influence on the abundance of their resources (functional web). The most effective control was exerted by sea urchin Stronglocentrotus and the chiton Katharina (Ricklefs 2008).

Is it possible for an individual with X-linked agammaglobulinemia to develop rheumatoid arthritis?

trasher [3.6K]

Explanation:

so X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the body's ability to fight infection. As the form of agammaglobulinemia that is X-linked, it is much more common in males.

So in rheumatoid arthritis Typically, stiffness begins in the joints of the hands. It usually comes on slowly, although it can come on suddenly and affect multiple joints over the course of one or two days... I hope this helped you answer your question :)
