D. All of the given statements are true in context of animal cloning.
Explanation:
Cloning is the method in which a similar genetic copy is produced.
Animal cloning is a complex process in which an organism of similar type is produced with same DNA to each other.
Mostly successfully cloned animals in live are cattle,sheep,goats...
Scientists have also cloned rats,mice,rabbits,horses...
This animal cloning is used for farming by the farmers which gives acceleration in their crop production.
Animal cloning have showed some adverse affects in sheep, and other mammal animals regarding issues in their organs like liver,heart,brain etc.
The success rate is very low like 10% in animal cloning due to many reasons such as surviving from birth to the cloned animals.
Answer:
This means that Antarctica once had a warmer climate.
Explanation:
Trees usually grow in warm climates, and Antarctica has little to no plant life.
Answer:
Explanation:
3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency, and symbol of the element.
For a neutral atom. number of protons =number of electrons=13
so since atomic number is the number of protons =13
mass number = protons + neutons =14+13 = 27
atomic number 13 is Aluminum (AL-(see periodic table)
The electronic structure for 13 electrons is 1s2s2p63s23p1
so Al has 3 electrons which are VALIENT and can react and when it loses the 3 it will have CHARGE OF +3
What we're looking for here is the gas sample's molar mass given its mass, pressure, volume, and temperature. Recalling the gas law, we have

or

where R is <span>0.08206 L atm / mol K, P is the given pressure, T is the temperature, and V is the volume.
Before applying the values given, it is important to make sure that they are to be converted to have consistent units with that of R.
</span>
Thus, we have
P = 736/ 729 = 0.968 atm
T = 28 + 273.15 = 301.15 K
V = 250/1000 = 0.250 L
Now, applying these converted values into the gas law, we have


Given that the mass of the sample is 0.430 g, we have

Thus, the gas sample has a molar mass of 43.9 g/mol.
Answer:
the correct answer is four decimal places
