Cattle egrets are birds that follow behind grazing cattle. The egrets eat the bugs that fly out of the grass as the cattle walk through. Which statement describes the relationship between the cattle egrets and the cattle?

A
predation, because the cattle egrets eat the bugs

B
mutualism, because both the cattle egrets and the cattle benefit

C
commensalism, because the cattle egret benefits, but the cattle neither benefits nor is harmed

D
parasitism, because the bugs might have bit the cattle egrets or the cattle and caused them harm

Answers

Answer: I think it's

The answer is C. commensalism. The egret doesn’t help nor does it harm the cattle, and just benefits off of it.

The relationship would be mutual if the egret did something extra, like eat bugs from off of the cattle. That way they would both benefit because the egret gets a snack and the cattle gets a free cleaning.

How much volume (in cm^3)is gained by a person who gains 11.8 lb of our fat? Human fat has a density of 0.918 g/cm^3

Answers

The volume (in cm³) gained by a person who gains 11.8 lb of fat is 5830.49 cm³

What is density?

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

How to convert pounds to grams

1 lb = 453.592 g

Therefore,

11.8 lb = 11.8 × 453.592

11.8 lb = 5352.3856 g

How to determine the volume Mass = 5352.3856 gDensity = 0.918 g/cm³Volume =?

Volume =  mass / density

Volume =  5352.3856 / 0.918

Volume = 5830.49 cm³

Determine the grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

Answers

There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

What is the mass of a substance?

The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.

To determine the energy from the 8g of carbohydrate, we have:

= 8g × 4 kcal/g (the corresponding calories of food type)

= 32 kcal

The energy from 2g of fat = 2g × 9 kcal/g

= 18 kcal

The energy from protein is calculated as:

= 140 kcal - 32 kcal - 18 kcal

= 90 kcal

The required mass of the protein in grams is:

[tex]\mathbf{= 90 \ kcal \times \dfrac{1}{4 \ kcal }}[/tex]

= 22.5 grams

Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.

What mass of water will be produced if 125.00 moles of oxygen are reacted completely?

Answers

Answer:

250 moles of H2O

Explanation:

I assume THIS is the equation you are using:

2H2 + O2    =====> 2 H2 O

  each mole of O2    results in twice as many H2O moles

     so 250

Is H2O an acid, ionic, or covalent compound?

Answers

Its a covalent compound because of the low difference in the electronegativity of Hydrogen and Oxygen as they share electrons forming covalent bonds

Answer:

Covalent Compound

Explanation:

H₂O is a covalent compound due to the electronegativity difference between hydrogen and oxygen. Covalent compounds involve elements with similar electronegativity values. Hydrogen has an EN value of 2.2 and oxygen has an EN value of 3.4. These values are not far enough apart to make them form ionic bonds between each other.

While water can act as an acid, it its purest form, H₂O is neutral.

There are 0.45 moles of Kr gas at a pressure of 1.35 atm and a temperature of 35°C. What volume would this gas occupy? (R= 0.0821 Mh/*))

Apply ideal gas equation

PV=nRTV=nRT/PV=0.45(0.0821)(273+35)/1.35V=0.45(0.0821)(308)/1.35V=8.42L

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.) ​

Answers

The quantity of morphine, the nurse should administer is 0.3 ml.

What is morphine?

Morphine is a drug which comes under the pain relieving drugs.

The quantity of morphine is 0.05 mg/kg

The weight of the baby is 3 kg.

Available morphine is 0.5 mg/mL.

0.05 x 3 = 0.15 mg

then, 0.15 mg / 0.5 = 0.3

Thus, the quantity of morphine, the nurse should administer is 0.3 ml.
