Answer:

c. the yolk is the correct answer.

Explanation:

The yolk part of the amniotic egg provides food for the embryo.

The yolk sac is present inside the egg and it provides nutrients to the developing embryo.

The yolk is the main source of nourishment for the embryo and carries all the fat.

The yolk part provides protein, energy, and water to the embryo.

yolk part becomes the umbilical cord through which food reaches the fetus and waste substances are removed.

What will be the theoretcal yield of tungsten(s) ,W, if 45.0 g of WO3 combines as completely as possible with 1.50 g of H2? WO3(
7nadin3 [17]

Answer:

Theoretical yield of tungsten produced = 35.6836915592  ≈ 35. 68 g

Explanation:

The chemical equation can be expressed as follows;

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

Note that the equation is already balanced.

Molecular Mass of WO3= 183.84 + 15.999 × 3 = 183.84 + 47.997  = 231.837 g

From the equation 1 mole of WO3 reacts with 3 mole of hydrogen molecule.

Molecular mass of tungsten(W) = 183.84 g

1 mole of tungsten was produced from the chemical equation.

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

From the equation,

231. 837 g of WO3 produces 183.84 g of tungsten

45.0 g of WO3 will produce ?

grams of tungsten produced = 183.84 × 45 /231.837

grams of tungsten produced = 8272.8 /231.837

Theoretical yield of tungsten produced = 35.6836915592  ≈ 35. 68 g

Assume that you have an illuminated suspension of Chlorella cells carrying out photosynthesis in the presence of 0.1% carbon dio
goldenfox [79]

Answer:

a. PGA down, RuBP up

Explanation:

RuBP, also known as Ribulose-1,5-bisphosphate is a molecule that assist in he fixation of carbon dioxide in the Calvin Cycle or light independent reaction of photosynthesis.

RuBP is combined with carbon dioxide using the enzyme known as rubisco to form an short-lived intermediate product which divides to form two 3-carbon molecule structure known as 3-phosphoglycerate.

<em>If the concentration of carbon dioxide is suddenly reduced, it thus means that the rate of production of 3-phosphoglycerate will reduce as carbon dioxide becomes a limiting factor. Hence, 3-phosphoglycerate's  concentration will reduce while more RuBP will become available as a result.</em>

The correct option is a.

(1) Respiration

(2) Nutrition

(3) Reproduction

(4) Movement

(5) Irritability

Explanation: A living specie is a specie that poses all the characteristics of a living organisms such MOVEMENT, REPRODUCTION, NUTRITION, IRRITABILITY,GROWTH, EXCRETION, REPRODUCTION AND DEATH.

Respiration is the process through which living organisms take in oxygen in order to break down food for the release of energy and carbon dioxide.

Nutrition is the process of feeding or intake of nutrients Airedale Terrier feeds on both plants and animals ( OMNIVORES).

Reproduction is the process through which the younger generation are brought to life Airedale Terrier reproduce through Sexual reproduction.

Movement is the change of location,Airedale Terrier moves from one point to another.

Airedale Terrier responds to different stimuli ranging from sound,light,touch, taste etc.
