2. How can different structures perform the same function?

Please help! And explain your answer with evidence please!

Answers

Explanation: Specialized Structures. ... This is because different organisms have developed unique structures that perform these functions and that do so in ways that fit their specific environments. So in this case, the structures are specialized to perform a specific function but also to fit the needs of a specific organism.

Due to unique structure an organism perform similar function if the structures are different.

Different structures perform the same function because different types of organisms have developed unique structures that helps them to perform function that is specific to their environments. The structures are specialized to perform a specific function but also to fit the needs of a specific organism.

Analogous structures refers to those structures which perform same function, but have different structures. Such type of organisms belongs to different ancestry but their body parts perform similar function so we can conclude that due to unique structure an organism perform similar function if the structures are different.

What are some of the reasons climate change is so bad for communities of color? HELP PLSSSSSSSS

Answers

Answer:

Here is a link that will explain more specifically.

https://www.greenamerica.org/climate-justice-all/people-color-are-front-lines-climate-crisis

Explanation:

The United Nations International Panel on Climate Change’s (IPCC) 2013 climate change science report states with “90 to 99 percent certainty” that more frequent and more severe weather events like droughts, intense heat waves, and “more frequent/ intense heavy rainfall events” are a consequence of the climate crisis. And it is communities of color that are bearing the brunt of those events, say many experts.

Other communities of color are also feeling the heat. In California, for example, record heat waves and droughts are affecting Latino communities hardest throughout the state, says Mario Santoyo of the California Latino Water Coalition.

As state farmers see their fruit and vegetable crops shrink from lack of water, it’s the state’s majority-Latino farmworkers who are struggling most as a result, as they scramble to get enough hours picking crops to earn a livable wage.

If an object is placed in water and has a density of 1.9 g/ml will the object float or sink?

Answers

Answer:

float

Explanation:

since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float

then 1.9g/ml < 1g/l

Answer:

it would sink

Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that

What is the crest and trough of a wave?

Answers

Answer:

Explanation:

A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is destructive interference: the resulting wave is the undisturbed line having zero amplitude.

A crest point on a wave is the minimum value of upward displacement within a cycle

Answers

Answer:

In many areas, rain or snowmelt on seasonally frozen soil is the single leading cause of severe runoff and erosion events. As soils freeze, ice blocks the soil pores, greatly diminishing the permeability of the soil. This is aggravated by the tendency of water to migrate to the freezing front, causing elevated ice content and frost heave.
