Answer:
36000 centimeters
Explanation:
If the average speed of a species of tortoise is 0.36 km/h, then it would be 36000 centimeters.
B. Density
C. Melting point
D. Color
Answer : The properties which would be the same among isotopes of the same element are Flammability and Color
Explanation :
Isotopes are the elements that have same number of electrons and protons but they differ in number of neutrons.
The chemical properties of an element are determined by its valence electrons and since isotope have same number of electrons, they have similar chemical properties.
But isotopes have different number of neutrons. Neutrons are the subatomic particles which are present in the nucleus. They are charge less particles and they have mass. Therefore when the elements have different number of neutrons, their atomic masses differ.
As a result, isotopes have different mass related physical properties.
Let us discuss the given properties now
1) Flammability : Flammability in simple words means the ability of the substance to catch fire or the ability to burn. This is mainly dependent on the reactivity which is in turn dependent on the number of electrons.
Since the isotopes have same number of electrons, they show similar flammability.
2) Density : Density is defined as mass per unit volume. This property involves mass and we know that isotopes have different masses. Therefore they have different densities too.
3) Melting point : Melting point is a physical property which is mainly dependent on the molecular weight of the substance. Since isotopes have different masses, they tend to show different melting points.
4) Color : The color of the element is mainly dependent on the arrangement of electrons around the nucleus. Isotopes have same number of electrons which means the arrangement would also be the same. Therefore the isotopes of the same element do not show different colors.
The properties which would be same among isotopes of the same element are
1) Flammability
4) Color
Answer: D. Color

So much for expert verified^^ smh
The mass ratio of potassium and selenium in the given compound is equal to 1 : 2.
The mass ratio also known as the percent composition by mass defines the proportion of a particular compound that consists of the constituent elements of that compound.
The percent composition by mass of a constituent element of a compound can be determined by the division of the mass of that element by the molar mass of the compound, followed by its multiplication by 100.
According to the law of constant proportion, a pure compound is always made up of the same elements combined together in a fixed proportion by weight.
Given the mass of the potassium (K) in the compound = 39 g
The mass of selenium (Se) in the compound = 78
The mass ratio of K and Se is 39 : 78
The simplest form of the ratio of potassium and selenium is 1 : 2.

2. Water molecules are split.
3. NADPH is formed.
In which locations do each of these events occur?
A. 1. photosystem II
2. photosystem III
3. photosystem I
B. 1. photosystem II
2. photosystem II
3. photosystem I
C. 1. photosystem I
2. photosystem I
3. photosystem II
D. 1. photosystem I
2. photosystem II
3. photosystem II
There are different photo systems involved in the phenomenon of photosynthesis which are units of protein
The two photo-systems are required for aerobic photosynthesis
Photosystem I
Photosystem II
The photosystem II absorbs energy [ thus light energy excites electron]
In photosystem II splits water molecules are split.
The excited electrons are transferred through cytochrome to photosystem I
In photosystem I NaDPH is formed.
thus answer is
B.
1. photosystem II
2. photosystem II
3. photosystem I
The correct locations for each of the events in photosynthesis are:
A. 1. photosystem II
2. photosystem III
Photosynthesis is the biological process by which green plants, algae, and certain bacteria convert light energy from the sun into chemical energy in the form of glucose (a type of sugar) and oxygen.
Photosynthesis is a fundamental process that sustains life on Earth and enables the existence of complex ecosystems and diverse organisms. It is the basis for the production of food, fuel, and other essential resources for both humans and the natural world.
