Answer:
----------------------------------------------
Reproduction is defined as the production of individuals of the same species, that is the next generation of the species.
----------------------------------------------
There are basically two types of reproduction - asexual and sexual.
----------------------------------------------
Asexual reproduction involves only one parent and the offspring is
genetically similar to the parent ...
----------------------------------------------
The different types of asexual reproduction are fission, budding, fragmentation, spore formation and vegetative propagation.
----------------------------------------------
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes combines with another to produce a organism composed of cells with two sets of chromosomes .
Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.

Answer:
ρ = 1.08 g/cm³
Explanation:
Step 1: Given data
Mass of the substance (m): 21.112 g
Volume of the substance (V): 19.5 cm³
Step 2: Calculate the density of the substance
The density (ρ) of a substance is equal to its mass divided by its volume.
ρ = m / V
ρ = 21.112 g / 19.5 cm³
ρ = 1.08 g/cm³
The density of the substance is 1.08 g/cm³.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
The mass of solid lead would displace exactly 234.6 liters of water should be <span>2,674,440</span>
Density of a substance is defined as the mass of the substance divided by the volume.
Density of the substance= 0.242 g cm⁻³
volume of the substance= 2.50 in³
As, 1 in³= 16.39 cm³
So, 2.50 in³= 16.39× 2.50 cm³=40.97 cm³
As ,
Mass=volume ×Density
Mass=40.97 × 0.242
Mass=9.916 g.
Answer:
a). ice melting is a physical change
b). paper burning is a chemical change
c). metal rusting is a chemical change
d). gas pressure increasing is a physical change
e). liquid evaporating is a physical change
f). food digesting is a chemical change
Explanation:
For all the above, In a physical change, the appearance or form of the matter changes but the kind of matter in the substance does not. However, in a chemical change, the kind of matter changes, and at least one new substance with new properties is formed.
a). ice melting - only form is changed
b). paper burning - By burning, ash is produced, which is different from paper
c). metal rusting - By rusting, the metal is oxidized and hence chemically changed
d). gas pressure increasing - only form is changed
e). liquid evaporating - only form is changed
f). food digesting - food is broken down into simpler molecules
