which model would represent asexual reproduction? explain you reasoning
Answer:
Answer) The first box represent the budding type of asexual reproduction . In budding due to the cell divison at the particular place in the organism , new individual will produced.
Second picture represent the budding in hydra. Budding is also a asexual reproduction.
Third type of asexual reproduction is found in plants it is vegetative reproduction.
Fourth is Binary fission . This is also a type of asexual reproduction, in which nucleus dicied into two new daughter cell via mitosis.Explanation:
What is the relationship between the concentration and the rate of the reaction?
negative
neutral
positive
Answer:
When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.
Answer:
Negative

In the formula
1N2 +3H2 → 2NH3 + 1H2
1 diatomic nitrogen (1N2) and 3 diatomic hydrogen (3H2) produce 2 ammonia (2NH3) with 1 diatomic hydrogen (1H2) left over. How can you change the formula so no diatomic hydrogen (H2) is left over?
(1 point)
Remove a H2 molecule from the left side of the equation.
Remove a NH3 molecule from the right side of the equation.
There is nothing that can be done to use the leftover molecules.
Add another N2 molecule to the left side of the equation.
Answer:
Remove a H2 molecule from the left side of the equation.

Recognize: What happens if a hypothesis is not supported.
Explain: Why do scientists practice scientific inquiry?
Describe: The behaviors scientists use in their work.
Answer:
If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. ... Either way, the process of experimentation often leads to whole new questions to explore.
Scientific inquiry uses evidence from observations and investigations to create logical explanations to answer questions related to science. Scientific inquiry is different from the scientific method. ... Scientific inquiry helps you think outside the box to understand the natural world.
Unlike social scientists, behavioral scientists collect empirical data and use experimental methods, including testing, controls and manipulated settings.
Explanation:
Which of these describes an exothermic reaction? Please help, today is the last day to submit anything.
Answer:
A, Heat is released as the reaction happens.
Explanation:
Exothermic reactions release heat and/or light and is a reaction in which the overall enthalpy is negative. The one your mouse is hovering over explains Nuclear Fission. The third one explains an endothermic reaction, as heat is absorbed in the reaction. The product being cold is actually one of the key characteristics of an endothermic reaction. Two liquids being mixed that forms a solid is called a precipitate.
What is phase change? How does matter change in phase?
Answer ASAP pls :(
Answer:
when the chemical composition of a substance change and it is not reversible it is called phase change.for example: turning milk in to yogurt
the heat energy absorbed or released during a chemical reaction is known as:
Why is fluorine more reactive than and bromine

What is the mass of 2.49 moles of sucrose?
your anwser would be 342 gmol Please mark branliest
Just get out that Periodic Table of the Elements, find the atomic masses for each atom, and add them up!
Carbon = 12
Hydrogen = 1
Oxygen = 16
C=12×12=144
H=1×22=22
O=16×11=176
Sucrose =144+22+176=342gmol
what is neutralisation??
Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.

1340.40 grams of Iron is made to react with nitric acid, find mass of ferri nitrite produced. Use the given equation 2 Fe + 6HNO3 2Fe (NO3 + 3H₂
The mass of ferric nitrate, Fe(NO₃)₃ produced from the reaction given the data is 5792.44 g
Balanced equation2Fe + 6HNO₃ –> 2Fe(NO₃)₃ + 3H₂
Molar mass of Fe = 56 g/mole
Mass of Fe from the balanced equation = 2 × 56 = 112 g
Molar mass of Fe(NO₃)₃ = 56 + 3[14 + (16×3)] = 242 g/mole
Mass of Fe(NO₃)₃ from the balanced equation = 2 × 242 = 484 g
SUMMARY
From the balanced equation above,
112 g of Fe reacted to produce 484 g of Fe(NO₃)₃
How to determine the mass of Fe(NO₃)₃ producedFrom the balanced equation above,
112 g of Fe reacted to produce 484 g of Fe(NO₃)₃
Therefore,
1340.4 g of Fe will react to produce = (1340.4 × 484) / 112 = 5792.44 g of Fe(NO₃)₃
Thus, 5792.44 g of Fe(NO₃)₃ were obtained from the reaction

What happens when you drop an egg on the ground from about 6 ft high?
Answer:
Gravity causes an object to fall to Earth when dropped. When the egg hits the ground with a given force, the ground exerts the same force back on the egg. If too large a force is delivered to the egg shell, the egg will crack.

4. Which elements have a completely full outermost energy level?
Answer:
Helium (He), neon (Ne), and argon (Ar), as group 18 elements, have outer electron shells that are full or satisfy the octet rule. This makes them highly stable as single atoms. Because of their non-reactivity, they are called the inert gases or noble gases.
