In an ecosystem, the physical characteristics of an organism are genetically passed down from one generation to another.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

What are Rhodium isotopes used for?
Answer:
Rhodium is used to make electrical contacts, as jewelry and in catalytic converters, but is most frequently used as an alloying agent in other materials, such as platinum and palladium. These alloys are used to make such things as furnace coils, electrodes for aircraft spark plugs and laboratory crucibles.
Explanation:
The number of......... in an atom is the difference between the mass number and the atomic number
A-Electrons
B-Neutrons
C-Protons
Answer: While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.

What does it mean if a solution is a "weak acid "? Strong acid? Give logical ph values for each
Answer:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.

c) A football feels hard on a hot day but feels softer in the evening
Answer: ^_^
Explanation:
its because during day time the ball becomes heated up and the air inside it try to come out as the heat air always try to go up swelling up the ball,
so in the evening when the air cools down the ball too cools down and air inside it also cools down making the ball feel soft,
Therefore, a football feels hard on a hot day but feels softer in the evening

which is the odd man out? diamond,coal, graphite, bronze.answer with an explanation
define p-block element?
Answer:
[tex]\boxed {\boxed {\sf D. \ Bronze}}[/tex]
Explanation:
Let's analyze the answer choices.
The first answer choices. diamond, coal, and graphite, all have something in common. They are allotropes of carbon. They are made of the same element, but each has a different arrangement of atoms, which leads to different properties.
Bronze is an alloy of copper, tin, and other metals. It's not an allotrope of carbon or related to the other answer choices. Therefore, it is the odd one out.
Does hydrogen have similar physical properties to alkali metals?
Answer:
YESExplanation:
because it contain 1 electron in its outermost shellWhat is the boiling point for butane?
Answer:
30.2°F
Explanation:
Butane, the liquid that can be seen inside a transparent lighter, boils at a temperature slightly under the point at which water freezes. So why doesn't the butane in the lighter boil? Butane does indeed boil at about a degree below 32 degrees Fahrenheit, but this is true only at normal atmospheric pressure. (:
the ____metals are in the first column. each of them has full shells, plus one extra electron sitting in a new, outer shell
A) Alkali
B) Alkali Earth
C) Arthropod
Answer:
The answer is A.
Explanation:
In periodic table, group 1 (1st column) are Alkali metals and group 2 (2nd column) are Alkali Earth metals.

1. X-linked (also called sex-linked traits) are inherited on the _____ chromosome.
Answer:
Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY). X-linked human genetic disorders are much more common in males than in females due to the X-linked inheritance pattern.
Explanation:
Sharon puts a large pot of water on the stove to boil pasta. Then she starts to make a tomato sauce. When the sauce is cooking, she looks at the pot of water and thinks the water level is much lower than it was. How does this diagram of part of the water cycle help Sharon explain what happened to the pasta water?
Answer:
1. A
2. C
Explanation:
For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.
What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.
A is the correct answer.
for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.
C is the correct answer.

. How many grams of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide? ____Cl2 + ____MgBr2 ___MgCl2 + ___Br2
Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.
Explanation:
The balanced chemical reaction is;
[tex]Cl_2+MgBr_2\rightarrow MgCl_2+Br_2[/tex]
[tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]MgBr_2[/tex] is the excess reagent.
According to stoichiometry :
1 mole of [tex]Cl_2[/tex] produces = 1 mole of [tex]MgCl_2[/tex]
Thus 2 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{1}{1}\times 2=2moles[/tex] of [tex]MgCl_2[/tex]
Mass of [tex]MgCl_2=moles\times {\text {Molar mass}}=2moles\times 95g/mol=190g[/tex]
Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide

explain how movements along faults generate earthquakes
Explanation:
When a plate moves it shifts the earth, and it can cause an earthquake.
A fault is where two of earth's tectonic plates come together. They can slide against the other, causing earthquakes, they can push against each other causing mountains to form, and they can move apart from each other, causing valleys or trenches.
