The radius of the belt increases and decreases depending on the
flux of charged particles that bombard the magnetic field of the earth around the
region , equator. This increase and decrease is dependent on the solar
activity. Solar storm release charged particles that interact with the magnetic
filed.
Answer: 20 fragments
Explanation:
This particular restriction enzyme has a 4 bp (base pair) recognition sequence therefore it will cleave once every 4ⁿ bases where n indicates the number pf bases in the recognition sequence.
- The recognition sequence is 4 bp therefore this restriction enzyme cleaves once every 4⁴ = 256 bases. This is the length of the restriction fragment.
- Calculate the number of fragments by dividing the total number of bases ( where you assume equal frequency of bases ie. A+T = C+G) by the length of the restriction base.
- therefore 5000bp/256bp = <u>19,53</u> now this number ca n be rounded up to 20.
- The expected number of fragments on the electrophoresis gel will be 20 fragments.
The correct answer is oviduct.
<span>When oocyte (female gamete) is released from the ovary during the ovulation, it travels down the fallopian tube (uterine tubes or oviduct) into the uterus, where it may become fertilised by a sperm. If fertilisation does not occur, the uterine wall and blood will be shed during menstruation.</span>
The answer is chloroplasts and mitochondria.
<span>When solar energy in the form of sunlight reaches a leaf of a plant, it passes through the leaf to chloroplasts. Chloroplasts contain pigment chlorophyll which is excited by light. As the result, </span>a series of chemical reactions occur in the chloroplasts and carbon dioxide and water are converted into glucose and oxygen. Now, glucose is broken down and transported into mitochondria where through different processes (Krebs cycle and electron transport chain) energy is produced in the form of ATP.<span>

<u>Removing waste from cel</u>l is NOT a function of the cytoskeleton
Answer: Option B
<u>Explanation:</u>
The cytoskeleton provides the shape and support to the cell. It has a rigid wall to give a shape and structure for the cell. It helps in the mobility of the cell and aids in the cell movement.
It also helps in transporting the communication signals from one cell to another. The cytoskeleton is made up of micro tubules, micro filaments and intermediate filaments. It also helps to move the nutrients within the cells. But it doesn’t help the removal of waste from the cell.
