sergeinik [125]

Answer:

Five days prior to ovulation and day of ovulation represents a six day fertile window of a women’s cycle

Explanation:

In the five days prior to ovulation and day of ovulation, the chances of conception are high. These six days represents the fertile window of a women’s cycle during which the sperm with a life span of five days and egg with a life span of 24 hours can fuse.

Do you think that bacterial uptake of a plasmid from the environment is a common event? why or why not?
snow_tiger [21]

 First Plasmid is a chromosomal element often a circular DNA.

The uptake of a plasmid from the environment is NOT a common event reason being, bacteria naturally take up DNA from their environment in a process called transformation. Thus if a bacterium takes up a piece of DNA that cannot be maintained in a cell then that cell will not survive.

Give two ways that the activities if the plants in the illustration to the right would change their ecosystem:
Zigmanuir [339]
I am answering under the assumption that those are cacti in the desert. Well as we know, cacti are producers they have the ability to synthesize their own food using photosynthesis which is a process that converts solar energy into glucose “food”. It has the ability to be a good source to small animals with its fruits and seeds. An example is, some insects feed off the nectar from the cacti. A second reason is that cacti are carbon sinks meaning that they take in carbon dioxide. Just to familiarize you the formula for photosynthesis is CO2 + H2O + energy equals glucose + O2 . Without carbon dioxide none of it is possible. Without cacti, CO2 levels would increase leading to bad affects.
