How do you know that an organism belongs to the animal kingdom
ki77a [65]

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.

How you would go about separating a mixture of salt and sand. Knowing that salt will dissolve in water. Device a method to separ
DanielleElmas [232]

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.

Equal volumes of two equimolar solutions of reactants a and b are mixed, and the reaction a+b→c occurs. at the end of 1h, a is 9
SVEN [57.7K]

<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.
