The process of sexual reproduction involves two parents, each contributing one gamete (and different types of genetic information, in shape of DNA). Gametes are produced by a process, called meiosis, which starts by the duplication of the chromosomes, followed by two rounds of cell divisions and halving of the chromosome number. Gametes have half the chromosome number of other adult cells of an organism. When two gametes merge, zygote is created. 

A key feature of meiosis is the exchange of chromosome pieces which occurs in the first division of this process, called recombination or crossing over. Recombination is a very important source of genetic variation between individuals of sexually reproducing species, and the driving force for the process of natural selection.

1. Review the information in the table below. Use the information to calculate rate of how many sandwiches are made in a 10-minu
PilotLPTM [1.2K]

Answer:

The answer to your question is given below.

Explanation:

Rate is simply defined as quantity per unit time. Mathematically it is represented as:

Rate = Quantity /time

Thus, we can obtain the rate as follow:

1. Quantity = 20 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 20/10

Rate = 2 sandwich per mins

2. Quantity = 30 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 30/10

Rate = 3 sandwich per mins

3. Quantity = 40 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 40/10

Rate = 4 sandwich per mins

4. Quantity = 50 sandwich

Time = 10 mins

Rate =?

Rate = Quantity /time

Rate = 50/10

Rate = 5 sandwich per mins

Thus, the complete table is given as follow:

Quantity >> Unit of measure >> Rate

10 >>>>>>> 10 min >>>>>>>>>> 1

20 >>>>>>> 10 min >>>>>>>>>> 2

30 >>>>>>> 10 min >>>>>>>>>> 3

40 >>>>>>> 10 min >>>>>>>>>> 4

50 >>>>>>> 10 min >>>>>>>>>> 5

An atom's Lewis dot structure has four dots. Which of the following elements could it be, and why?
castortr0y [4]

Answer: The atom that it would be would be beryllium. This is because a Lewis dot structure counts the electrons. If there is four electrons, than there is 4 protons, unless it is a cation or anion. This means the atom has an atomic  number of 4 and that element is beryllium.
