Why do you think astronomers even classify dwarf planets? Why not just catalog planets and leave it at that?
To further define what qualifies as a planet, scientists assign labels to planets and dwarf planets.
What are Dwarf planets?The case might be made that solid stuff in space could be referred to as a "planet" if scientists lacked a classification scheme.
The identification of planets that potentially host life is made possible by classification thresholds. Smaller than any of the eight classical planets but nonetheless a world in its own right, a dwarf planet is a small planetary-mass object that is in direct orbit of the Sun.
Pluto is the archetype for a dwarf planet. Planetary geologists are interested in dwarf planets because they might be geologically active worlds, a hypothesis that was confirmed in 2015 by the Dawn mission to Ceres and the New Horizons mission to Pluto.
Therefore, To further define what qualifies as a planet, scientists assign labels to planets and dwarf planets.

Why do cars rust more easily in wet climates than drier climates?
Answer:
Wet climates obviously have more water than driers climates. Metals, when subject to water have the tendency to oxidize (rust). Therefore, if water is barely present in a climate, then oxidation is also least likely to occur.

What is the acceleration of.5-kg bowling ball when a 10-n force is applied
Answer:
The acceleration of ball is 2 m.s⁻²
Explanation:
Given data:
Mass of ball = 5 kg
Force applied = 10 N
Acceleration = ?
Solution:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
a = 10 N / 5 kg
N = Kgm.s⁻²
a = 10 Kgm.s⁻² / 5 kg
a = 2 m.s⁻²

Which biological macromolecule is the most important and why
Answer:
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.
Explanation:
pleaseeeeeee mark me the brainliest
The most important macromolecules are nucleic acids. DNA and RNA, which carry the genetic information and translate it for protein building, for the correct functioning of the cell.
Nucleic Acids
Nucleic acids are DNA and RNA.
They are macromolecules composed of different nucleotides joined by their extremes.
Nucleotides are subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.
Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base.
Nitrogenated bases are purines and pyrimidines.
DNA ⇒ Adenine and guanine, Thymine and Cytosine.RNA ⇒ Adenine and guanine, Uracil and Cytosine.The nucleotidic sequence codifies or specifies the genetic instructions to the correct development and functioning of the organism.
DNA molecule keeps the genetic information about the sequence of amino acids in the protein, and RNA is in charge of translating that information .
Hence, the most important macromolecules are DNA and RNA, which carry the genetic information and translate it for protein building, for the correct functioning of the cell.

What is the diffrenece between an ionic bond and a convalent bond
Answer: Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.

Identify correct statement from the following
1)A hypothesis is a possible that can be tested.
2) Variables are the factors that can affect the outcome of investigation.
3) Always hypothesis will be true
4) If hypothesis is incorrect test can be done with other variables
Answer:
The answer is statement 1, 2, and 3
Explanation:
A hypothesis is a starting point for further investigation, therefore a hypothesis will always be a possibility at least until it is tested.
Variable is a factor that is liable to vary or change.
A hypothesis without being tested is merely a statement or an explanation made on the basis of limited evidence. Therefore it is unsure whether the said statement is true or not.
A hypothesis can still be proven by further investigation with different variables

List the 3 Parts of the Modern Cell Theory
Answer:
1. All organisms are made of cells
Cells are the smallest unit of life. Each cell is a membrane of semi-permeable phospholipids wrapped around cytosol or a solution of water and dissolved solutes. All cells rely on DNA to hold the information necessary to produce the molecules they use to obtain energy. Although the methods for obtaining energy vary widely, all organism obtain energy to grow and reproduce. This first tenet of the cell theory is mostly true, but the discovery of viruses lead to complications. Viruses, while they use DNA or RNA to reproduce, do not have cells or cellular membranes. Viruses typically use a host cell to replicate. In this case, the virus appears to be living, but does not create its own cell. Some scientist argue that viruses are not living, thus cell theory is not violated.
2. Cells are the most fundamental unit of life
Organisms can be single cells, which hold all of the components necessary for a metabolism, or they can be more complex. More complex organisms divide the various metabolic tasks into different groups of cells, called tissues. These tissues are arranged in compartments with membranes that separate them from other tissues. These groups of tissues are called organs. A group of organs functioning together is an organism, or an individual creature. Each cell is distinct from the cells next to it, and each functions independently, while contributing to the output of the organism as a whole. Again, modern cell theory is a bit more complicated because advances in science have revealed many different organelles within cells. These organelles are bound in membranes themselves, and serve different functions for eukaryotic cells. Some scientists argue that these are more fundamental units, but other scientists argue that like an organ outside of an organism, they could not function without the cell.
3. Cells come from other cells
As far as we know, no cell on Earth currently has arisen spontaneously. All cells are the result of cell division. When a cell is large enough, it replicates its DNA and important components. These components can then be divided into two daughter cells, which are copies of each other. Variations in the DNA in each cell can lead to changes in how they function, which can result in them dividing at different rates. The cell that reproduces more than the other cell will pass on more of its DNA. The purpose of every cell or organism is to reproduce the DNA in cells.
This third tenet of the cell theory has yet to be disproven. No scientist has ever created a functioning cell without replicating another cell, although some scientists are trying. If they were successful, it would give proof to how life could have evolved. It is thought that a self-replicating molecule mutated, developed the ability to produce a membrane, and thus the first cell was born. The cell was such a successful form of life that all life since has used the same basic template.
The parts of the modern cell theory are:
All living things are made up of at least one cellCell is the basic and fundamental unit of lifeAll cells arise from pre-existing cellsCELL THEORY:
Cell theory is a universally accepted theory that explains the features of life in three statements.The cell theory was composed in 1890's by three scientists namely: Rudolf Virchow, Mathias Scleiden and Theodor Schwann.
