2021 Science Interim assessment 3 of 373 of 37 Items Question This chart describes some beak and toe adaptations that help four bird species survive in different habitats. Based on these adaptations, which table best matches the bird species to its environment?

When you look at different bird beaks, you’re seeing a great example of something called adaptation. Adaptations are traits that developed to perform a certain function and allow organisms to thrive in their environment. Although one adaptation might be very useful for a certain species in a specific environment, that same trait might not be useful for another species in a different environment.

To understand how adaptations arise, it helps to understand the process of evolution. Populations of plants, animals and other living organisms change over many, many generations. Scientists call this process natural selection

Explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
