Answer:Answer:
For 1: The correct answer is Model 1, 2, and 4.
For 2: The correct answer is Option 1.
Explanation:
For 1:
An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).
Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.
For 2:
A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example: is a compound made out of atoms of carbon and oxygen.
Hence, the correct answer is Option 2.
Answer:
cognitive therapy is a type of psychotherapy to treat human mood disorders such as depression.

Answer:
Transport vesicles will not be brought to either the Golgi apparatus or the plasma membrane.
Explanation:
Microtubules forms part of the structure of the cytoskeleton. It is a polymer of tubulins.
Apart from maintaining the cell structure, cytoskeleton plays a role in transportation in a cell.
A Constructive secretory pathway is an exocytosis process found in all eukaryotic cells, in which transport vesicles destined for the plasma membrane leave the trans-Golgi network in a steady stream
A disruption on microtubules will lead to a change in structure of the cytoplasm. It will not be able to perform its function therefore transport vesicles will not be brought to either the plasma membrane or the golgi apparatus.
Let us consider each statement separately. A zygote is the result of the fusion of two gametes (reproductive cells) and thus only appears in sexual reproduction. For the same reason, E) is wrong; meiosis is a step in the making of gametes and again, a plant that reproduces asexually does not produce gametes. B) is also wrong since (healthy) members of the same species have the same number of chromosomes. The leaf cells of the daughter plant will have 24 chromosomes. The only case where this would not hold, is the case of sexual reproduction, where the gametes of the new organism have half the chromosomes of the ancestor organisms. Hence, C and D are correct. We have already justified D. As far as C is concerned, in asexual reproduction we have that every organism passes his whole genome to his offspring and this creates a lot of clones next to each other. Every plant in a garden of a species that reproduces asexually may be genetically identical and some biologists consider them for that reason as the same organism!
