Copperhead snakes can reproduce both sexually and asexually. which option describes a situation where sexual reproduction is more advantageous for the copperhead snake.
A. a new disease develops , so having more genetic variation among there off spring is an advantage.
B. a new type of pray arrives in the environment , so they have more food sources.
C. a short and mild winter makes the environment more livable for them and all the other organisms in the area.
D. they migrate to a new location where prey and shelter are more abundant and easier to find.
Answer:
Answer A:
a new disease develops , so having more genetic variation among there off spring is an advantage.
Not 100% sure but A seems the most likely answer.
Explanation:
The question is asking where sexual reproduction is more of an advantage and I'd say that having more genetic variation would be caused by sexual reproduction and not as much or at all in asexual reproduction.
with B, C, and D. It wouldn't really be an advantage to do one or the other in this context.

A student must use 225 mL of hot water(cwater=4.184 J/g°C) in a lab procedure. Calculate theamount of heat required to raise the temperature of225 mL of water from 20.0 °C to 100.0 °C.
Answer: q = 64 kJ
Explanation:
As you know, a substance's specific heat tells you how much heat is required to increase the temperature of
1 g
of that sample by
1
∘
C
.
In water's case, you know that its specific heat is equal to
4.18
J
g
∘
C
. This tells you that in order to increase the temperature of
1 g
of water by
1
∘
C
, you need to supply
4.18 J
of heat.
How much heat would you need to increase the temperature of
200 g
of water by
1
∘
C
?
Well, if you need
4.18 J
per gram to increase its temperature by
1
∘
C
, it follows that you will need
200
times more heat to get this done.
Likewise, if you were to increase the temperature of
1 g
of water by
76
∘
C
, you'd need
76
times more heat than when increasing the temperature of
1 g
by
1
∘
C
.
Combine these two requirements and you get the total amount of heat required to increase the temperature of
200 g
of water by
76
∘
C
.
Mathematically, this is expressed using the following equation
q
=
m
⋅
c
⋅
Δ
T
, where
q
- heat absorbed/lost
m
- the mass of the sample
c
- the specific heat of the substance
Δ
T
- the change in temperature, defined as final temperature minus initial temperature
Plug in your values to get
q
=
200

What two factors must be held constant for density to be a constant ratio?
The two factors which must be held constant for density to be a constant ratio are: Mass and Volume
As we know, the density of a material is simply defined as the ratio of mass to volume.
In essence, Density = Mass/VolumeConsequently, To obtain a constant ratio for density, the mass and volume of the material in discuss must be kept constant.

the various geologic settings in which rocks can melt, metamorphose, or become sediment are ultimately generated by
Geological settings whereby there is melting of rock as well as formation of sediments can be attributed to Plate tectonics .
Plate tectonics can be regarded as theory which explained the Earth's outer shell and how its been divided into solid rocks as well as slabs and its often referred to as Plate.
Plate tectonics explained that there is a large-scale motion plates which Earth's lithosphere is made up.Tectonic processes started about 3.3 and 3.5 billion years ago. Through the generation of Tectonic plate, there are melting of rocks as well as generation of sedimentsThe types of boundaries that exist between those tectonic plates can be categorized into 4, base on the the movement of the plates, and these are;divergent boundariesconvergent boundariestransform fault boundaries plate boundary zonesTherefore, plate tectonic gives explanation about Earth's outer shell.

Explanation:
why do you think that sodium chloride has to be heated to 800c before melting, but candle wax will start to melt at 50c?
Answer:
Sodium chloride is an ionic compound which makes it stronger and have a higher melting and boiling point. Candle wax is a covalent compound so it has a low melting point.

Determine whether each of the reactions given below would be spontaneous or not. Please justify your answer in each case.
A. Fe2+ (aq) + Al (s) → Al3+(aq) + Fe (s)
B. Pb2+ (aq) + Sn (s) → Sn2+ (aq) + Pb (s)
C. Mg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s)
A spontaneous reaction is one in which the change in free energy is negative and the standard cell potential is positive.
For a redox reaction to be spontaneous, the electrode potential of the cell must be positive and this depends on the relative electrode potentials of the species involved in the reaction. A metal can not displace a metal above it in the electrochemical series from solution.
Based on this;
Fe2+ (aq) + Al (s) → Al3+(aq) + Fe (s) is spontaneous because iron is lower than aluminium in the electrochemical seriesPb2+ (aq) + Sn (s) → Sn2+ (aq) + Pb (s) is spontaneous because lead is lower than tin in the seriesMg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s) is not spontaneous because magnesium is above silver in the series.Lean more: https://brainly.com/question/24556237
