Answer:
Yes
Explanation:
They are a unique type of eukaryote because they lack an important organelle: mitochondria. Mitochondria are essential for producing cellular energy in most eukaryotic cells. However, due to its habitat, it is able to acquire energy from a process called sulfur mobilization.
They are significant because they challenge the idea that eukaryotes need mitochondria to be classified as eukaryotic. However, they have other membrane-bound organelles such as a nucleus and Golgi apparatus, meaning they remain eukaryotic.
Research suggest they lost their mitochondria over time, rather than never having had them throughout their ancestry.
Because of all these reasons, they still meet the definition of a eukaryote.
D
Molecules consist of multiple atoms put together to create a new form.
Answer:
The correct answer is CaO > LiBr > KI.
Explanation:
Lattice energy is directly proportional to the charge and is inversely proportional to the size. The compound LiBr comprises Li+ and Br- ions, KI comprises K+ and I- ions, and CaO comprise Ca²⁺ and O²⁻ ions.
With the increase in the charge, there will be an increase in lattice energy. In the given case, the lattice energy of CaO will be the highest due to the presence of +2 and -2 ions. K⁺ ions are larger than Li⁺ ion, and I⁻ ions are larger than Br⁻ ion.
The distance between Li⁺ and Br⁻ ions in LiBr is less in comparison to the distance between K⁺ and I⁻ ions in KI. As a consequence, the lattice energy of LiBr is greater than KI. Therefore, CaO exhibits the largest lattice energy, while KI the smallest.
ion, proton
Explanation:
Ions and protons have profound relationships.
An ion is an atom that has lost or gained electrons.
A proton is a positively charged subatomic particle.
What is the relationship between an ion and a proton?
- In an atom, there are three fundamental particles.
- Protons are the positively charged particles located in the nucleus of atoms.
- Electrons are the negatively charged particles orbiting round an atom.
- Neutrons have no charges and they occupy the nucleus with protons.
Atoms are electrically neutral and this implies that they have equal number of protons and electrons.
In an ion, the number of protons and electrons differ.
For positive charged ions, the number of protons is more suggesting they have lost electrons.
For negatively charged ions. the number of protons is less suggesting they must have added electrons.
Compound are combinations of different atoms.

Answer:
Actually, The Henderson - Hasselbalch equation allows you to calculate the pH of the buffer by using the pKa of the weak acid and the ratio that exists between the concentrations of the weak cid and conjugate base. The pKa of formic acid is equal to 3.75. In this case, the pH of the solution will be equal to the acid's pKa .
