Explain what information about populations cannot be gathered when looking solely at population pyramid data.

Answers

Answer:

Hi there, so the population pyramid visualizes two variables which are sex and age but it doesn't tell us the actual number of population within a region it only collects the sex (female and males) and the ages (ranging from infant to elderly).

So the only thing that population pyramid data can't collect is the actual population in number.

Hope this helped :)  

The population pyramid, therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex (females and men) (ranging from infant to elderly).

What is the population?

As a result, the only thing the population pyramid data cannot measure is the size of the population.

Population pyramids do have certain restrictions, though. It is typically impossible to tell the relative contributions of various demographic processes on population age structure since they simply provide the size of each age-sex group in the population.

Therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex.

Answer:  the given protein segment contains 20 amino acids

The given segment of the polypeptide chain is made up of four different types of amino acids, and each amino acid is connected to each other by the peptide bond, and the chain elongates from the N terminal to the C terminal.

What is the significance of amino acids?

There are 20 different standard amino acids that take part in polypeptide chain synthesis, and those are categorized into some particular types such as hydrophobic amino acids, hydrophilic amino acids, charged and uncharged amino acids, etc., and different compositions of the amino acids make different types of proteins. The polypeptide chain is generally synthesized from the N terminal to the C terminal, and here in the given diagram, there are four amino acids, and each amino acid has an amino group, a carboxylic group, a hydrogen group, and one side chain bonded to a single central carbon atom.

Hence, the given segment of the polypeptide chain is made up of four different types of amino acids.

The proper function of the stomates on the leaf (and therefore, the function of water and CO2 movement) is influenced most by which element

Answers

Answer:

Sunlight.

Explanation:

Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.

Answers

Answer: The theory states that the earth's crust is divided into massive slabs known as tectonic plates.

Explanation:

These plates move on the mantle which is a layer made of magma, which consists of semisolid rocks.The heat from earth's core causes convection currents much like in a beaker full of water.But, here the force developed by the magma is so great that it slowly moves the plates like boats on sea over millions of years.

Answer: The theory of tectonic plates says that the Earth's outer crust, the lithosphere, is separated into plates that are covering this entire world.
