In biological taxonomy, the next smallest classification group after Order is Family. This is part of the classification system that ranges from broad categories to more specific ones, which include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
In the biological classification system, the next smallest group after Order is Family. This refers to the hierarchy of taxonomic ranks in biology, where organisms are classified from broad categories to more specific ones. The sequence of ranks from broad to specific is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each rank gets more specific as you go down the list. So, if you're looking at the rank just beneath Order, it would be Family. For instance, in the Order Carnivora (carnivores) one of the Families is Felidae (cats).

It would increase because of less gravity
It would decrease because of less gravity
None of the above
Answer:
Explanation:
you are on the moon or on Earth. Mass is an intrinsic property of matter and is a measure of the amount of matter in an object. It does not depend on the location of the object or the gravitational field it is in. Therefore, your mass would be the same on the moon as it is on Earth.
It would be the same on the moon as on Earth
b) lighting a match from a matchbook
c) cutting snowflakes out of paper
d) melting butter for popcorn
B: To determine the color of the minerals
C: To classify minerals
D: To identify minerals
and D. to identify minerals
Answer: D: Identify minerals
Explanation: If you can figure out the chemical makeup or the use of a mineral, you can identify what kind of mineral it is.
B. Even though for a majority of the race they accelerated at the same rate, Beverly won because her initial acceleration was greater than Carl’s.
C.Beverly accelerated at a greater rate for the entire race.
D. Carl accelerated at a greater rate for the entire race
The correct option is B.
Acceleration is defined as the rate of velocity of a body per unit time; that is, acceleration is given by the ratio of velocity and time. Looking at the graph given above, it can be seen that, the two runners started with different initial velocity; Beverly started with the initial velocity of 15 m/s while Carl started with the initial velocity of 10 m/s. For the rest of the race, the two runners maintains similar acceleration but Beverly won because her initial velocity was higher.
F = (mass)(acceleration) = ma
m = 55 kg
Vi = 20 m/s
t = 0.5 s
Vf = 0 m/s (since she was put to rest)
a=(Vf-Vi)/t
a=(0-20)/5
a = 40 m/s^2 (decelerating)
F = ma = (55 kg)(40 m/s^2)
F = 2200 N
Hope this answer will be a good help for you.

When a calcium atom loses two electrons, it becomes positively charged because it has more protons than electrons. In this case, since two electrons are lost, the calcium ion has a charge of +2.
When an atom loses or gains electrons, it undergoes a process called ionization, resulting in the formation of an ion. In the case of calcium (Ca), it typically loses two electrons to achieve a more stable electron configuration.
A neutral calcium atom has 20 electrons, with the electronic configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². By losing its two outermost electrons from the 4s orbital, it forms a calcium ion (Ca²⁺) with 18 electrons.
The loss of two negatively charged electrons leaves the calcium ion with a net positive charge. The charge on an ion is indicated by a superscript after the ion symbol. In this case, the superscript is +2, denoting that the calcium ion has a charge of +2.
Hence, the correct answer is +2.
