Answer: The percentage would be 19%, 51% and 30%.

Explanation:

Since we have given that

Number of food eaten by X = 57

Number of food eaten by Y = 153

Number of food eaten by Z = 90

Total number of food eaten = 57+153+90=300

So, Food percentage of flock X = \dfrac{57}{300}\times 100=19\%

Food percentage of flock Y = \dfrac{153}{300}\times 100=51\%

Food percentage of flock Z = \dfrac{90}{300}\times 100=30\%

Hence, the percentage would be 19%, 51% and 30%.

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon
Luda [366]

Answer:

B

Explanation:

When humans dig-up fossil fuels and burn them to power the modern world, <u>carbon flows between the Geosphere/lithosphere and the atmosphere.</u>

Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.

<em>Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.</em>

The correct option is B.

Threonine is a standard amino acid with a polar side chain.Identify the chiral centers in threonine. a. the carboxyl carbon b. t
luda_lava [24]

Answer:

Threonine has two chiral centers.

The correct options are c. carbon b and d. carbon c

Explanation:

Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.

Define groundwater, and list some anthropogenic (human) sources of groundwater pollution. Why do many scientists consider ground
joja [24]

Explanation:

Groundwater is the freshwater present below the earth's surface. It originates from the rain, ice, melting snow.

Some anthropogenic sources of groundwater pollution are

  • Aluminum.
  • Sulfur.
  • Arsenic.
  • Nitrates.
  • Fluoride.

Groundwater pollution has more problems than surface water pollution because groundwater is mostly hidden and it is very difficult to view, manage and monitor.

Groundwater holds its contamination and pollutants that cause pollution whereas surface water rinses their contamination and pollutants.

Suppose a one-year old child is playing with a toy near an electrical out-let. He sticks part of the toy into the outlet. He get
Papessa [141]

Answer:

UCS: sticks part of the toy into the electrical outlet

UCR: frightened and crying

CS: toy

CR: frightened to toy

Explanation:

Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.

<u>Unconditioned stimulus</u> (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.

<u>Unconditioned response</u> (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.

<u>Conditioned stimulus</u> (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.

<u>Conditioned response</u> (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.
