In mammals and amphibians? An enucleated egg, a donor nucleus (preferably from an early developmental stage such as a blastocyst), and a means to stimulate the egg to be activated as if it had just been fertilized (poking with a needle is sometimes enough)

Or cloning into a vector as in at the level of DNA?
A vector with positve and negative selection markers (like antibiotic resistance and drug susceptibility), an insert, DNA ligase and restriction enzymes, buffer for restriction and ligation. Or if you are doing cloning by PCR, then you need primers, template, nucleotides, RNA pol like Taq polymerase etc.

Which best explains what happens to the carbon atoms in carbon dioxide during photosynthesis?A They are incorporated into molecu

Mademuasel [1]

Answer:

A They are incorporated into molecules of sugar.

Explanation:

Photosynthesis is the metabolic process whereby sugar molecules are synthesized by plants in the presence of sunlight (light energy). For this process to occur, carbon dioxide (CO2) and water (H2O) are needed as reactants from external sources. Hence, the photosynthetic equation is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

According to this question, the carbon atoms in carbon dioxide are incorporated into sugar molecule (glucose). It takes 6 carbon atoms to produce one glucose molecule (C6H12O6). This process involves series of reaction in the light-independent stage of photosynthesis to occur.

Calculate the speed. 1. If a car travels 800m in 30 seconds how fast is it going?

Alex787 [66]

Answer:

s = 26.7 m/s

Explanation:

Given data:

Distance travel = 800 m

Time taken = 30 sec

Speed of car = ?

Solution:

Formula:

S = d/t

s = speed

d = distance

t = time

by putting values.

s = 800 m/ 30 s

s = 26.7 m/s

Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of potassium sulfide and chromium

alexgriva [62]

Answer:

S²⁻(aq) + Cr²⁺(aq) ⇄ CrS(s)

Explanation:

The molecular equation includes all the species in the molecular form. Usually, it is useful to write this first to balance the equation. This is a double displacement reaction.

K₂S(aq) + Cr(NO₃)₂(aq) ⇄ 2 KNO₃(aq) + CrS(s)

The full ionic equation includes all ions and the species that no dot dissociate in water.

2 K⁺(aq) + S²⁻(aq) + Cr²⁺(aq) + 2 NO₃⁻(aq) ⇄ 2 K⁺(aq) + 2 NO₃⁻(aq) + CrS(s)

The net ionic equation includes only those ions that participate in the reaction and the species that do not dissociate in water.

S²⁻(aq) + Cr²⁺(aq) ⇄ CrS(s)

Predict the most likely bond type for the following.

Amiraneli [1.4K]

Answer:

The three major types of bond are ionic, polar covalent, and covalent bonds. Ionic occurs majorly between metals and non-metals, which allows sharing of electrons to form an ionic compound. Whereas covalent bonding calls for complete transfer of electrons between atoms. Polar covalent bonds have unequaly shared electron-pair between two atoms.

Explanation:

a. Cu (Copper)- ionic bonding 

b. KCl (Potassium Chloride) - ionic bonding 

c. Si (Silicon) - covalent bonding 

d. CdTe (Cadmium Telluride) - polar covalent bonding 

e. ZnTe (Zinc Telluride)- polar covalent bonding
