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.

You have a solution that is 0.02M formate (HCOO-) and 0.03M formic acid (HCOOH), which has a Ka of 1.8x10-4. What is the pH of t
lisov135 [29]

Answer:

3.6

Explanation:

Step 1: Given data

  • Concentration of formic acid: 0.03 M
  • Concentration of formate ion: 0.02 M
  • Acid dissociation constant (Ka): 1.8 × 10⁻⁴

Step 2: Calculate the pH

We have a buffer system formed by a weak acid (HCOOH) and its conjugate base (HCOO⁻). We can calculate the pH using the <em>Henderson-Hasselbach equation</em>.

pH = pKa +log\frac{[base]}{[acid]} = -log 1.8 \times 10^{-4} + log \frac{0.02}{0.03} = 3.6

How many grams of KCIO3 are needed to produce 5.00 of O2 at STP?
Arlecino [84]
2KClO₃ → 2KCl + 3O₂

mole ratio of KClO₃ to O₂ is 2 : 3

∴ if moles of O₂ = 5 mol

then moles of KClO₃ = \frac{5 mol   *   2}{3}

                            = 3.33 mol


Mass of KClO₃ needed = mol of KClO₃ × molar mass of KClO₃

                                      = 3.33 mol × ((39 × 1) + (35.5 × 1) + (16 × 3) g/mol

                                      = 407.93 g

In the force equation, which two variables have a direct relationship? Which two have an indirect/inverse relationship?
zhuklara [117]

Answer:

if the dependent and independent variable go up its direct but if one of them goes up and another goes down its indirect

Explanation:

for example the more mass an object has the less speed it has that's indirect but the less salt you add to water the less time you have to wait for it to boil

i hope this was useful
