Both algae and amoeba are in the domain Eukarya. Which of the following characteristics do they most likely share?

Chemistry
1 answer:
TiliK225 [7]3 years ago
5 0

Answer: They both have cells with membrane- bound organelles.

Explanation:

The domain eukarya includes the eukaryotic organisms, which range in diversity from single celled to multicellular. These organisms have cells that have membrane bound organelles, nucleus is present in them. These organisms range from simple to complex life cycles.

Hence, both algae and amoeba which belong to domain eukarya have membrane bound organelles in their cells.

Define Aqua regia and write a short note on it
meriva

Answer:

Explanation:

Aqua regia is a strong and very concentrated acid formed by mixing Hydrochloric acid(HCl) and nitric acid.

The acid is very corrosive due to its formulation and it nearly reacts to dissolve all substances including the unreactive gold metal. It is formed by mixing the two acids in a proportion of 1:3, i.e HCl in 3 parts and nitric acid in 1 part.

The mixture dissolves a wide range of metals

Suppose you wanted to monitor a pH change between 8.7 and 7.7. Which indicator would be most appropriate
mariarad [96]

Answer:

Phenol red /

Thymol blue

Explanation:

pH indicator referred to halochromic chemical compound which is added in small amounts to a solution for the determination of pH visually.

An indicator can be described as a chemical detector for both hydronium and hydrogen ions as far as Arrhenius model is concerned, an indicator are usually weak acids or bases, and when they are which dissolved in water , there would be a dissociation process and ions is formed.

There are different types of indicator used in the laboratory depending on the pH values of the solution examples are thymol blue, bromothymol blue, thymol blue, phenolphthalein and methyl red

Thymol blue is an indicator that transit between red to yellow when the pH is between the range of 1.2–2.8 and also transit from from yellow to blue when the pH 8.0–9.6. It an indicator that usually have brownish-green or reddish-brown crystalline powder

Phenol red is pH indicator which is yellow in colour when it is below 6.8 pH and has a very bright pink colour when used with pH above 8.2

An atom of 105In has a mass of 104.914558 amu. Calculate the binding energy in MeV per NUCLEON. Enter your answer with 3 signifi
joja [24]

Answer:

8.46

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

Also, atomic number of I = 549

Thus, the number of protons = 49

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Mass number = Number of protons + Number of neutrons

105 =  49 + Number of neutrons

Number of neutrons = 56

Mass of neutron = 1.008665 amu

Mass of proton = 1.007825 amu

Calculated mass = Number of protons*Mass of proton + Number of neutrons*Mass of neutron

Thus,

Calculated mass = (49*1.007825 + 56*1.008665) amu = 105.868665 amu

Mass defect = Δm = |105.868665 - 104.914558| amu = 0.954107 amu

The conversion of amu to MeV is shown below as:-

1 amu = 931.5 MeV

<u>So, Energy = 0.954107*931.5 MeV/atom = 888.750671 MeV/atom</u>

Also, 1 atom has 105 nucleons (Protons+neutrons)

<u>So, Energy = 888.750671 MeV/105nucleons = 8.46 MeV/nucleon</u>

<u>Answer:- 8.46</u>

Which describes the boundary where earthquake activity occurs along rift valleys? divergent boundary in the ocean divergent boun
Mila [183]

Answer:

Divergent boundary on land

Explanation:

A rift valley is a lowland region that forms where Earth’s tectonic plates move apart (diverge), or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

Rift valleys are created by tectonic activity and not the process of erosion.

Tectonic plates are huge, rocky slabs of Earth's lithosphere—its crust and upper mantle. Tectonic plates are constantly in motion—shifting against each other in fault zones, falling beneath one another in a process called subduction, crashing against one another at convergent plate boundaries, and tearing apart from each other at divergent plate boundaries.

The most well-known rift valley on Earth is probably the so-called "Great Rift Valley System" which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.
