antonio is considering that since the spiders came first, it cannot have 'derived traits' from anything. spiders themselves are the ancestralspecies of the insects
The probability is 1/16 that a gamete will receive only paternal chromosomes. In life
cycles that alternate between haploid and diploid stages, fertilization doubles
the number of chromosomes per cell, The pairing of chromosomes along
their lengths , which is essential for crossing over is referred to as synapsis
Do you have different answers that go with the question?
Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.
Answer:
The correct answer will be- the free energy change will be +13 kcal/mol.
Explanation:
The free energy change of a chemical reaction is the measure of the spontaneity of the reaction in which the negative value of free energy represents that reaction is exergonic while positive value represents that reaction is endergonic.
In the given question, if the free-energy change is 13 kcal/mol for the hydrolysis of ATP to ADP + Pi which releases energy used by the cells then reversal of the reaction that is the formation of ATP molecules from the ADP and Pi requires energy which will be the same energy required to break the ATP.
This shows that 13kcal/mol energy will be used but with a positive sign as the energy is needed or the reaction is endergonic.
