Answer and explanation:
The <em>Animalia</em> Kingdom is defined according to its main characteristics, which are common to all animals: eukaryotic (their cells have defined nuclei), multicellular and heterotrophic organisms, which obtain their food by ingesting nutrients from the environment (with the exception of some endoparasites, which are nourished by absorbing nutrients from host fluids).
In addition, living beings in the animal kingdom begin their development from an egg cell or zygote, which arises from the fertilization of the egg by the sperm.
Thus, sexual reproduction is always present in the animals' life cycles. However, this does not mean that asexual reproduction does not happen, it occurs and is very important in some groups.
Separating a mixture of salt and sand will involve two main techniques such as filtration and evaporation.
<h3>What is Filtration?</h3>
This is a technique which is used to separate a fluid from a solid matter such as sand etc.
Since salt dissolves in the water, the fluid is collected using the filter paper placed inside the funnel. After which it enters the Erlenmeyer flask and is heated to allow for evaporation of water and collection of the salt.

A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together.
Answer:
it gains energy in a quantized amount
Explanation:
when we describe the energy of a particle as a quantized ,we mean that only certain values of energy are allowed....it can only gain the exact amount of energy needed to reach one of the higher energy levels
hope this helps :)
<span>a)
</span>First order
in A and zero order in B
<span>ln [A]
= (ln 0.1) (2) + ln Ao = ln 0.01 + ln Ao = ln 0.01 Ao = 1.0% of A will remain</span>
<span>b)
</span>First
order in A and first order in B
<span>1/[A] – 1/[A]0= kt where t+=1 and k=9</span>
[A]/[A]=1/19=0.053=5.3%
<span>c)
</span>Zero
order in both A and B
<span>[A]0-[A] = kt</span>
Then at 2
hours [A]=0 All of it has reacted.
