Answer: 1s²2s²2p³ or it can also be 3s²2p³

Answer:

false

Explanation:

the temperature of a substance can not remain constant as the substance changes from solid to liquid then finllay from liquid to gas. This is so because as a solid is heated it changes state and once it rechanges it boiling point it changes to gas or vapour.

Answer:

New findings from NASA's Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.

Answer:

(4) sperm - transports genetic material

Explanation:

Which reproductive structure is correctly paired with its function'?

(1) uterus - usual site of fertilization

(2) testis - usual location for egg development

(3) ovary - delivers nutrients to the embryo

(4) sperm - transports genetic material

Solution:

The uterus (also known as the womb) is where the fertiled egg (foetus) stays until it is ready to be delivered. The usual site of fertilization  is the fallopian tube.

The testis is responsible for the production of sperm and hormones. The uterus is where the egg development takes place.

The ovary is responsible for the production of egg and hormones. The embryo receives nutrient through the fetus.

The sperm transports genetic material to the ovum.

Answer:

4

Explanation:

because ovaries def do not deliver nutrients to the embryo thats the placenta and the testis are DEF not a site for egg development and the uterus is not where fertilization happens i believe its where the fetus is kept and therefore the only correct answer is 4 :)

Answer:

An ammeter is a device that is used to measures the amount of current flowing in a circuit and a voltmeter measure electric potential difference in an electric circuit between two points.

An Ammeter is connected in series because of its low resistance capacity and it will be connected in parallel it can get damaged due to high current. A voltmeter is connected in parallel in an electric circuit because the potential difference remains the same when connected in parallel.

Answer:

Bro, its so obvious. Its electrical conductivity.

Explanation:

Plastic is an insulator thus it can protect conducting material from shortage of current as well for the safety of users. Thus, option 4 is correct.

Conductivity of a material is the measure of its ability to pass electric current through it. Based on this there are three types of materials namely conductors, insulators and semiconductors.

Conductors are materials highly conducting at room temperature. Semiconductors are not conducting at room  temperature but can be conducting at higher temperatures.

Insulators does not conduct electricity at any situation. Hence, insulators are used to coat conducting wires and to protect from electric shock. Plastic s an insulator which can cover conducting copper wire for safety. Thus, option 4 is correct.

The options are;

A) Carbon dioxide

B) Carbon Monoxide

C) Chloro fluoro carbon and methane

D) Refrigerant Freon

Answer:

B) Carbon Monoxide

Explanation:

Greenhouse gases are compounds available in the atmosphere which are capable of absorbing infrared radiation, thereby making heat in the atmosphere to be trapped and held there. The most common ones are carbon Monoxide, carbon dioxide, chloro-fluoro carbon, methane, nitrous oxide, ozone and freon. Out of them, the one that is the most dangerous and doesn't contribute to climate change is carbon monoxide because it is a silent killer gas

Thus, option B is correct

Answer: Metal atoms lose electrons from their outer shell when they form ions: the ions formed are positive, because they have more protons than electrons.

Answer:

a solute is a substance that is dissolved in the solvent (liquid)

a solvent is a substance that dissolves a solute (solid)

a solution is the mixture of both the solute and solvent forming uniform mixture

The statement that compares the strengths of electric forces between particlesof matter is Hydrogen bonds and metallic bonds are weaker than ionic bonds.

Electric forces are strong forces or power that exist between atoms of molecules which help to bind those are together and allow the flow of electric charges.

Answer:

A) [tex]6.5\times 10^{23}\ \text{molecules}[/tex]

Explanation:

m = Mass of water = 38.9

M = Molar mass of water = 18 g/mol

[tex]N_A[/tex] = Avogadro's number = [tex]6.022\times 10^{23}\ \text{mol}^{-1}[/tex]

The reaction of electrolysis would be

[tex]2H_2O(l)\rightarrow 2H_2(g)+O_2(g)[/tex]

Number of moles of [tex]H_2O[/tex]

[tex]n=\dfrac{m}{M}\\\Rightarrow n=\dfrac{38.9}{18}\ \text{mol}[/tex]

From the reaction it can be seen that 2 moles of [tex]H_2O[/tex] gives 1 mole of [tex]O_2[/tex]

So, number of moles of [tex]O_2[/tex] produced is

[tex]\dfrac{38.9}{18}\times \dfrac{1}{2}=1.081\ \text{mol}[/tex]

Number of molecules

[tex]1.081N_A=1.081\times 6.022\times 10^{23}\\ =6.5\times 10^{23}[/tex]

So, [tex]6.5\times 10^{23}\ \text{molecules}[/tex] of oxygen is produced.

Answer:

The independent variable is the volume of the strong acid added to the strong base

The dependent variable is the effect of the combination of the acid and base on the pH

Explanation:

The given parameters are;

The rate at which Ashley is adding the strong acid to the strong base = 1 mL per each time

The volume of the strong base to which Ashley is adding the acid = 30 mL

Therefore;

The testing, or independent variable of the experiment = The number of 1 mL volume of the strong acid Ashley adds to the strong base

The outcome, or dependent variable of the experiment = The measured (change) effect on the pH.

Answer: As we all are aware that life on Earth is existed due to several environmental changes and there are several scientific factors of sustainability that support the survival and evolution of life on Earth.

Scientific factors of sustainability include solar energy, chemical cycle, and biodiversity that supported life on Earth. solar energy helps all organism and especially producers to gain energy and store the energy which further used in chemical cycles of transferring energy to other trophic levels.

Chemical cycle also involves the interaction of biotic and abiotic envrionment with each other that leads to environmental changes as well as organisms adapt themselves accordingly.

Biodiversity maintains the balance in the ecosystem and prevent dominancy of one organism otherwise it can lead to scarcity and organism would not be able to survive. Variation in biodiversity due to random mating  in the same species leads to evolution and produces new species of organisms.  

Hence, scientific factors of sustainability play major role in survival and evolution of life on the Earth.
