What is the name for this type of reproduction?​
mario62 [17]

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.

Question 9
Shkiper50 [21]

Answer: There are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.

Explanation:

Given: M_{1} = 1.0 M,    V_{1} = ?

M_{2} = 0.1 M,    V_{2} = 200 mL

Formula used is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute values into the above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\1.0 M \times V_{1} = 0.1 M \times 200 mL\\V_{1} = \frac{0.1 M \times 200 mL}{1.0 M}\\= 20 mL

Thus, we can conclude that there are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.

How much pressure would 0.8 moles of a gas at 370K exert if it occupied 17.3L of space
dezoksy [38]

Answer:

1.40 atm is the pressure for the gas

Explanation:

An easy problem to solve with the Ideal Gases Law:

P . V = n . R .T

T° = 370K

V = 17.3L

n = 0.8 mol

Let's replace data → P . 17.3L = 0.8mol . 0.082L.atm/mol.K . 370K

P = (0.8mol . 0.082L.atm/mol.K . 370K) / 17.3L = 1.40 atm
