help me guys please I need answer immediately
Answer:
Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens.
Nuptial flight: a flight of sexually mature social insects (as bees) in which mating takes place and which is usually a prelude to the forming of a new colony; especially : the mass flight and mating of winged sexual forms of ants after leaving the parent nest.
Cocoon: a silky case spun by the larvae of many insects for protection in the pupal stage.
Group B:
Not sure) a- Keep in cold places because when there are changes in weather, it could help the silkworm come out faster.
b-They live together in a large, well organized group and bees engage in complex activities that required works from other community members in the bee society.
c- i dont know this part sorry =(
d-The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature Bee larvae have been shown to be an excellent food source for rearing insects
Explanation:
Answer:
For group A
Explanation:
1. A royal jelly is a substance that is secreted by the worker honeybee's. This is fed to a potential queen bee to help them grow.
2. The nupital flight is part of reproduction for ants, termites, and most bee species.
3. A cocoon is used for the resting pupal stage in the life cycle of animals like butterflies and moths. It is a protective covering and is silky.
4. They feed on mulberry leaves.

How GM food are produced?
What is genetic modification (GM) of crops and how is it done? GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants.
Answer:
GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.
Is this an alpha or beta decay?
Answer:
In Alpha Decay the nucleus is split into 2 parts with one of these parts – the alpha particle – zooming off into space. The nucleus has its atomic number reduced by 2 and its mass number is reduced by 4 (2 protons and 2 neutrons are removed). In Beta Decay (minus) a neutron turns into a proton.
Explanation:
container has 3 moles of gas with a volume of 60 liters and at a temperature of 250 K, Calculate the pressure inside the container in kPa
Answer:
103.98 kpa
Explanation:
Pv= nRT
Where
P= pressure of the system=
n= number of moles= 3 moles
T= temperature= 250 K
Volume of the container= 60 liters
R= 0.0821L.atm/K.mol
Substitute the values
Pv= nRT
P= nRT/ V
= (3×0.0821×250)/60
= 1.026 Atm
1atm= 101325 Pascal
1.026 atm= X
= 103984 pasca
Convert to kilopascal
= 103984 pasca /1000
= 103.98 kpascal
112 g of aluminum carbide react with 174 g water to produce methane and aluminum hydroxide in the reaction shown below.
2 Al4C3(s) + 12 H2O(l) → 3 CH4(g) + 4 Al(OH)3(s)
If aluminum carbide is the limiting reactant, how many moles of the excess reactant are left over
a
37.3 mol
b
4.68 mol
c
7.33 mol
d
131.94 mol
Answer: 4.999 moles of excess reactant will be left over.
Explanation:
Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.
Excess reagent is defined as the reagent which is left behind after the completion of the reaction.
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] .....(1)
Given mass of aluminium carbide = 112 g
Molar mass of aluminium carbide = 143.96 g/mol
Putting values in equation 1:
[tex]\text{Moles of aluminium carbide}=\frac{112g}{143.96g/mol}=0.778mol[/tex]
For the given chemical reaction:
[tex]2Al_4C_3(s)+12H_2O(l)\rightarrow 3CH_4(g)+4Al(OH)_3(s)[/tex]
By the stoichiometry of the reaction:
2 moles of aluminium carbide reacts with 12 moles of water
So, 0.778 moles of aluminium carbide will react with = [tex]\frac{12}{2}\times 0.778=4.668 mol[/tex] of water
Given mass of water = 174 g
Molar mass of water = 18 g/mol
Putting values in equation 1:
[tex]\text{Moles of water}=\frac{174g}{18g/mol}=9.667mol[/tex]
Moles of excess reactant (water) left = 9.667 - 4.668 = 4.999 moles
Hence, 4.999 moles of excess reactant will be left over.

Explanation:
one third of the united states carbon consumption is used to operate what
Answer:
The carbon returns to the atmosphere as carbon dioxide. Cars, factories, and power plants rely on these fossil fuels to operate. In the year 2000, vehicles were the source of one-third of all carbon dioxide emitted in the United States.
Explanation:
The movement of water from an area of high concentration to one of low concentration through a semipermeable membrane is called ?
