The right matches are:

1. nuclear envelope  is matched with b.

2.centriole  is matched with  a.

3.interphase is matched with j.

4.furrowing  is matched with h.  

5.anaphase  is matched with g.

6.spindle apparatus is matched with f.

7.chromatin is matched with i.

8.haploid is matched with c.

9.meiosis is matched with e.  

10.homologous chromosomes is matched with d.


Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.

A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product. The model is based
lions [1.4K]

Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.

    The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.

The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

The cells in this part of a plant form long, vertical tubes. What is the most
3241004551 [841]

Answer:

D. The tubes allow water and nutrients to be transported throughout

the plant.

Explanation:

option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.

option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.

option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.

option B could possibly be right but option D is better suited.

Intermolecular attraction describes how the particles that make up matter are attracted to each other. The graph below compares
krok68 [10]

Anything that  says further apart is incorrect. So B is incorrect.

A is correct as near as I can tell.

C is not correct. The particles. I think C is the right answer supplied with the wrong reason. Regretfully, you can't choose it.

Same answer as C for D. Right answer wrong reason.

Answer A.
