A) 5
Half-life is the time it will take for a quantity to reduce to half its initial value. In this case, uranium will undergo radioactive decay, and after 700 mil years, 5 of the 10 uranium atoms will have decayed.
The three phases of the human ovarian cycle are:
<span><span>1. </span>Follicular phase</span>
This is a phase controlled by estradiol, during which follicles in the ovary mature.
<span><span>2. </span>Ovulation</span>
This is a phase in which eggs are released from the ovaries when the follicles rupture.
<span><span>3. </span>Luteal phase</span>
<span>This is the phase is under the control of progesterone. At the beginning of luteal phase, corpus luteum is formed and it ends in either pregnancy or luteolysis.</span>
If one wishes to clone a gene using typical restriction endonucleases, how does the restriction endonuclease identify the appropriate cut sites in the genome using the palindromic sequence.
Restriction endonucleases are a family of enzymes usually found in bacteria that cuts DNA at a specific sequence called recognition site. There are three type of restriction endonuclease Type I, Type II, and Type III.
Each endonuclease recognizes a particular sequence called palindromic sequence which is a sequence that reads the same sequence in both the strands either reading from the 3 prime end or 5 prime end.
The endonuclease cuts the palindromic sequence in such a way that it produces sticky ends.

Answer:
- Use bikes and non motor engines to get short distances BIKES is a good option.
- Support electricaly charged vehicles
- Turn off your car when you are not driving

- reuse old notebooks that are not finished for the next year
- Get outdoors and spread your carbon dioxide
- try playing ball games and not video games so much becasue it means you use electricity that is generated by fossil
- Turn off lights before bed
- dont keep the TV on all the time.
Explanation:
Hope that helps :)
I found this radiography online, i hope it's the same:
1- <span>Spinous process
2- Atlas ( it's the first vertebra)
3- Axis </span><span>( it's the second vertebra)
4- Transverse process
5- </span><span><span>Intervertebral disc</span> (present between vertebras)
6- body of the vertebra
the occipital bone is a reference that it's the posterior side, while the mandibule indicates it's anterior.
