Answer choices:
Florida plants are full of leaves and make fruit.
Florida plants begin to sprout seeds.
Florida plants go dormant from the heat.
Florida plants start to change color.
Answer:I think it’s the first option because of high temperatures there would be more evaporation and precipitation which would give plants water and exposure to the sun makes plants make food because of the photosynthesis process.

How does the melting point of a substance indicate the strength of its intermolecular forces of attraction?
Answer:
he substance with more intermolecular attraction will be having higher melting point. So higher the melting point,higher the force of attraction will be
Explanation:
Melting point is the minimum temperature at which a substancr start to melt.As melting happens the particles force of attraction will be lowering.Substance which have higher force of attraction,
It will take a little time to reach the melting point because the particles does not move due to its force of attraction. When required heat energy is supplied it starts to melt..

Why does a graph of CO2 emissions through time have annual fluctuations that correspond with the seasons?
I give Brainliest! Please no links
Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. ... As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most.

At least 10 g of KClO3 must dissolve at a temperature of 35 0C. As a result, choice (C) is accurate.
What is meant by Boiling point?The temperature at which a liquid's vapor pressure equals the pressure around it and the liquid turns into a vapor is known as the boiling point of a substance
A liquid's boiling point varies depending on the atmospheric pressure in the area. Lower pressure, or partial vacuum, results in a liquid's boiling point being lower than it would be under atmospheric pressure.
As a result, water boils at 99.97 °C (211.95 °F) at sea level but at 93.4 °C (200.1 °F) at 1,905 m (6,250 ft)[3] altitude under standard pressure. Different liquids will boil at various temperatures at a given pressure at the freezing point

What is the density of an object with the mass of 204 grams? It displaces 17ml of water. please help!
Answer:
12 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
We have
[tex]density = \frac{204}{17} \\ = 12[/tex]

2. A sample of gas has a pressure of 195 kPa and a volume of 3.50 L. If the pressure
is increased to 150 kPa, what is the new volume?
Answer:
4.55 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{195000 \times 3.5}{150000} = \frac{682500}{150000} \\ = 4.55[/tex]
We have the final answer as
4.55 LHope this helps you
CAN I PLEASE GET SOME HELP?
You accidentally spilled an unknown liquid on a lab bench. It spreads out across the lab bench and quickly evaporates. What can you infer about the structure of the molecules? Explain your reasoning.
Answer:
See note under explanation
Explanation:
That the particles have mostly non-polar structures or, have a very low degree of electronegativity (i.e. very low or no attractive interactions) so that particle - particle interaction favors the gas phase when not in an equilibrium based environment. That is, a closed container of liquid were liquid phase is in equilibrium with gas phase. However, when not in a closed container; i.e., spilled, particles evaporate rapidly moving into the gas phase from liquid phase.
Hope this helps. :-)

This hollow tube along the back of an animal with nerves running inside or beside it is a characteristic of chordates.
1. nervous system
2. spinal cord
3. spine
4. notochord
Spinal cord is a hollow tube along the back of an animal with nerves running inside or beside it is a characteristic of chordates.
What are chordates?
A chordate is an animal of the phylum Chordata. All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits,. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation.
In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cephalochordates. These CSIs provide molecular means to reliably distinguish chordates from all other Metazoa.

How many moles of solute are present in 150mL of 0.30 mol/L NaOH solution
ourse
Answer:
0.045 moles of NaOH
Explanation:
When this units are together mol/L, we talk about M, molarity.
This kind of concentration shows the relation between moles of solute which are contained in 1L of solution.
In this case, our NaOH solution is 0.30 M
M = mol/L
Then, M . L = mol
We convert volume to L → 150 mL . 1L /1000 mL = 0.150L
0.150 L . 0.30mol/L = 0.045 moles

Fractional distillation is used to separated
A, an insoluble substance from a soluble volatile substance
B. substances which are adsorbed differently, and which differ in their solubility in a solvent
c. liquids with differing boiling points
D gas, liquid or solid impurities from a mixture
Answer: Fractional distillation is used to separate liquids with differing boiling points
Explanation:
Sublimation is used to separate volatile substance from a non volatile substance where volatile substance gets converted from solid to gas.
Fractional distillation is separation of a liquid mixture into fractions which differ in boiling points by means of distillation by use of a fractionating column.
Chromatography is a separation method where different rates of adsortion of different components is used to separate substances.
