Answer 1
I’m hoping you’re looking for the scientific answer, in which case I think I might be able to help you. Essentially, although we only see chlorophyll (the green pigment in leaves), there are other pigments. These pigments are called accessory pigments. Chlorophyll is the dominant pigment, which is why we do not see these other pigments. However, colder temperatures destroy chlorophyll and break it down. Chlorophyll is constantly break down and being replaced but, the cold temperatures slow down this process, allowing the accessory pigments to show through. Hope this helps!

A table with a list price of x dollars is discounted by 15% and then discounted an additional 12%. What is the final sale price of the tablet, in terms of x?

Answers

The final sale price of the tablet is 0.748x

What is discount?

Discount results in the reduction of the selling price of the product, which makes it more attractive for the customer.

Reduction in price makes a psychological impact on the customer which results in the purchase. The two types of discount offered are trade discount and cash discount.

x is discounted by 15%

= x × 15/100

= 15x /100

The new price = x -15x/100

= 85x/100

It is discounted again by 12%

85 x/100 × 12/100

= 1020x/10000

= 102x/100

The final sale price

= 85x /100 - 102 x/1000

= (850x-102 x)/1000

= 748x/1000

= 0.748x

Therefore the final sale price is 0.748x

The web development team is having difficulty connecting by ssh.

Answers

There could be a variety of reasons why the web development team is having difficulty connecting by ssh. Some common issues include incorrect login credentials, network issues firewall blocking the connection, or server configuration problems.

First, make sure that the login credentials are correct and that the correct port is being used. If that is not the issue, check for any network issues that may be preventing the connection. If there are no network issues, check the firewall settings to ensure that the connection is not being blocked. Lastly, make sure that the server configuration is correct and that there are no issues with the ssh daemon.

If none of these solutions work, it may be best to contact the network or server administrator for assistance.

The complete combustion of ethanol, c2h5oh (fw = 46. 0 g/mol), proceeds as follows: c2h5oh(l) + 3 o2(g) → 2 co2(g) + 3 h2o(l) δh = −555 kj what is the enthalpy change for combustion of 15. 0 g of ethanol?.

Answers

The enthalpy change for combustion of 15.0 g of ethanol in the chemical reaction is -180.93 kJ.

The enthalpy change for combustion of 15.0 g of ethanol can be calculated using the equation:

ΔH = (ΔH°/mol) × (mol/mass) × mass

Where ΔH° is the standard enthalpy change for the reaction, mol is the number of moles of ethanol, and mass is the mass of ethanol in grams.

Given that the standard enthalpy change for the combustion of ethanol is -555 kJ, the molecular weight of ethanol is 46.0 g/mol, and the mass of ethanol is 15.0 g, we can plug these values into the equation:

ΔH = (-555 kJ/mol) × (1 mol/46.0 g) × (15.0 g)

Simplifying the equation gives:

ΔH = (-555 kJ/mol) × (0.326 mol)

ΔH = -180.93 kJ

Therefore, the enthalpy change for combustion of 15.0 g of ethanol is -180.93 kJ.

Simulate an environment with equal amounts of insects and seeds, but no fruit. Which flock will be able to eat the most? The least? Why?

Answers

In an environment with equal amounts of insects and seeds, but no fruit, the flock that will be able to eat the most will be the one that has a diet consisting mainly of insects and seeds.

The advantage of the abundance

This is because they will be able to take advantage of the abundance of these two types of food sources and consume them at a higher rate than flocks that have a diet consisting mainly of fruit.

On the other hand, the flock that will be able to eat the least will be the one that has a diet consisting mainly of fruit. This is because there are no fruit available in this environment, and they will have to rely on the limited amount of insects and seeds available to them. This will result in them consuming less food overall and potentially struggling to find enough food to sustain themselves.

Overall, the ability of a flock to consume the most food in this environment will depend on their dietary preferences and the availability of different types of food sources. Flocks that have a diet consisting mainly of insects and seeds will be able to consume the most food, while flocks that have a diet consisting mainly of fruit will be able to consume the least.
