Which reproductive structure is correctly paired with its functions
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 :)

Ammeter is connected in series and voltmeter is connected in parallel to the electric load in an electric circuit .
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.

How does a positive ion form?
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.

Under careful and controlled supervision, Ashley is slowly adding 1 mL of a strong acid at a time to 30 mL of a strong base to measure the effect it had on the pH. What is the testing (independent) and outcome (dependent) variable of this experiment? What would a good control be?
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.

Plastic is used to cover the copper wire in the power codes of appliances because plastic differs from copper in _________. 1. Destiny 2. Hardness. 3. Phrase at room temperature 4. Electrical conductivity
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.
What is conductivity ?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.

Calculate the amounts of each substance in the reaction below if an initial amount of 0.400 moles are brought together with an initial amount of 2.29 moles of Cl2 in a 1.00 L vessel
Complete Question
Calculate the equilibrium amounts of each substance in the reaction below if an initial amount of 0.400 moles of CO are brought together with an initial amount of 2.20 moles of Cl2 in a 1.00 L vessel and then equilibrium is established at 900 K. Kc at this temperature = 0.800. COCl2(g) CO(g) + Cl2(g)
Answer:
The amount of each substance at equilibrium is
[tex][COCl_2 ] = 0.282 \ M[/tex]
[tex][CO] = 0.12 \ M[/tex]
[tex][Cl_2] = 2.008 \ M[/tex]
Explanation:
From the question we are told that
The initial amount of CO is [tex]n_1 = 0.400[/tex]
The initial amount of [tex]Cl_2[/tex] is [tex]n_2 = 2.20 \ moles[/tex]
The volume of the vessel is [tex]V = 1.0 \ L[/tex]
The temperature is [tex]T = 900 \ K[/tex]
The equilibrium constant at the given temperature is [tex]K_c = 0.800[/tex]
The reaction is
[tex]COCl_2 \underset{}{\stackrel{}{\rightleftharpoons}} CO + Cl_2[/tex]
Now Generating an I C E table
[tex]COCl_2 \ \ \ \ \underset{}{\stackrel{}{\rightleftharpoons}} \ \ \ \ \ \ \ \ \ CO \ \ \ \ \ \ \ \ \ \ + \ \ \ \ Cl_2[/tex]
Initial [I] 0 0.400 2.20
Change [C ] + x -x - x
Equilibrium [E ] x 0.400- x 2.20 - x
Here x is the amount in terms of concentration by which [tex]COCl_2[/tex] and [tex]CO[/tex] and [tex]Cl_2[/tex] decreased during the reaction
Generally the equilibrium constant is mathematically represented as
[tex]K_c = \frac{[CO] [Cl_2]}{[COCl_2]}[/tex]
=> [tex]0.800 = \frac{[0.400 - x] [2.20 - x ]}{[x]}[/tex]
=> [tex]0.800 x = [0.400 - x ] * [ 2.20 - x ][/tex]
=> [tex]x = 0.282 \ M[/tex]
Generally at equilibrium the amount of [tex]COCl_2[/tex] present is
[tex][COCl_2 ] = 0.282 \ M[/tex]
Generally the equilibrium the amount of [tex]CO[/tex] present is
[tex][CO] = 0.400 - 0.282[/tex]
=> [tex][CO] = 0.12 \ M[/tex]
Generally the equilibrium the amount of [tex]Cl_2[/tex] present is
[tex][Cl_2 ] = 2.29 - 0.282[/tex]
=> [tex][Cl_2] = 2.008 \ M[/tex]

What is the evidence that Mars once had flowing liquid water? Why is this important?
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:
Assuming the element Magnesium atom is neutral
Proton # = 12
Neutron # = 12
Electron # = 12
Explanation:
In a neutral atom the number of protons and electrons is always equal
The atomic number tells the number of protons (12) in this case
The Atomic Mass describes the mass of the protons + mass of neutrons, so if you take 12 (number of protons) away you are left with 12 and some change(number of neutrons)

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.
