How do you know that an organism belongs to the animal kingdom

Chemistry
1 answer:
ki77a [65]2 years ago
8 0

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.

1.15.7 cm3 of HCl completely neutralised 25 cm3 of LiOH. The HCl was 2 mol/dm3.The equation is :
Whitepunk [10]

Answer:

C₂ = 1.26 mol/dm³

Explanation:

Given data:

Volume of HCl =V₁ =  15.7 cm³

Volume of LiOH = V₂ =  25 cm³

Concentration of HCl =C₁ = 2 mol/dm³

Concentration of LiOH =C₂=  ?

Solution:

Chemical equation:

LiOH + HCl    →     LiCl + H₂O

Formula:

C₁V₁   = C₂V₂

by putting values,

15.7 cm₃× 2 mol/dm³ = C₂× 25 cm³

C₂ = 15.7 cm₃× 2 mol/dm³ / 25 cm³

C₂ = 31.4 cm₃.mol/dm³ / 25 cm³

C₂ = 1.26 mol/dm³

A 22.4 kg object is accelerating at 1.40 m/s2. What net force is being applied to the object?
kaheart [24]

Answer:

<h3>The answer is 31.36 N</h3>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 22.4 × 1.4

We have the final answer as

<h3>31.36 N</h3>
