What does energy have to do with reproduction

Chemistry
1 answer:
murzikaleks [220]3 years ago
6 0

Answer:

Nutrition has a significant impact on numerous reproductive functions including hormone production, folliculogenesis, fertilization, and early embryonic development

Explanation:

This intimate association is because reproductive processes are energetically expensive, and the brain must temper the fertility of individuals to match nutritional availability.Reproduction function in mammals can be inhibited when food availability is low or when increased energy demands are not met by compensatory food intake such as in short-term and chronic withdrawal of nutrients.This very close alignment with the food supply is more important in females, where pregnancy and lactation are linked to considerable energetic expenses, needed for the nurture of embryos and newborns. In fact, her reproductive outcome can be seriously altered and even life threatening to both the mother and offspring when nutritional imbalance occurs. In order to keep constant body energy stores, in mammals, a series of homeostatic events leading to maintenance of energy balance are activate when a state of energy scarcity or abundance occurs.

Mass of oxygen produced from 0.02 moles
faust18 [17]

Answer:

0.64 g O₂

Explanation:

I am assuming you meant 0.02 moles of O₂. In that case, convert moles to mass via stoichiometry:

0.02 mol O₂ x 32 g O₂/1 mol O₂ = 0.64 g O₂

How many moles of gas at 58° C does it take to fill a 1.75 L flask to a pressure of 12.5 kPa? Please help I will give brainliest
marin [14]

Answer:

0.008 moles of gas are present

Explanation:

Given data:

Volume of gas = 1.75 L

Number of moles =  ?

Temperature of gas = 58°C

Pressure of gas = 12.5 KPa

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

58+273 = 331 K

Pressure = 12.5/101 = 0.12 atm

by putting values in formula:

0.12 atm× 1.75 L = n× 0.0821 atm.L/ mol.K   ×331 K

0.21 atm.L = n× 27.17atm.L/ mol

n = 0.21 atm.L /27.17atm.L/ mol

n = 0.008 mol

Considering the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq) Which ion would NOT be present in
Allisa [31]

Answer:

The question is incomplete and confusing.

  • In the complete ionic equation you write all the ions that are formed. Those are: Pb²⁺, NO₃⁻, K⁺, and I⁻. They all are present in the complete ionic equation.

  • In the net ionic equation, the spectator ions do not appear. They are: NO₃⁻ and K⁺. They would not be present in the net ionic equation, but they do in the complete ionic equation.

See below the details.

Explanation:

Which compound will not form ions?

<u />

<u>1. Write the balanced molecular equation:</u>

  • Pb(NO₃)₂(aq) + 2KI(aq) → PbI₂(s) + 2KNO₃(aq)

<u />

<u>2. Write the ionizations for the ionic aqueous compounds:</u>

<u />

  • Pb(NO₃)₂(aq) →  Pb⁺²(aq) + 2NO₃⁻(aq)

  • 2KI(aq) → 2K⁺(aq) + 2I⁻(aq)

  • 2KNO₃(aq) → 2K⁺(aq) + 2NO₃⁻(aq)

<u />

<u>3. Write the complete ionic equation:</u>

Pb⁺²(aq) + 2NO₃⁻(aq) + 2K⁺(aq) + 2I⁻(aq) → PbI₂(s) +  2K⁺(aq) + 2NO₃⁻(aq)

Hence, since PbI₂(s) does not ionize, but stays in solid form, it will not form ions.

All, Pb⁺², NO₃⁻, K⁺, and I⁻ will be present in the total ionic equation.

It is in the net ionic equation that the spectator ions are removed. Those, are NO₃⁻ and K⁺, because they are on both sides of the complete ionic equation.
