Answer:
18th of July
Explanation:
Given that each quarter of a moon phase occurs after seven days, hence, if a 1st quarter moon phase appears on the night of July 4th, the approximate date on which a 3rd quarter moon will appear in the night sky on the 18th of July.
This is because, after the first quarter of a moon phase of July 4th, the second quarter of a moon phase will occur on the 11th of July, while the third quarter will occur on the 18th of July.
New cells are typically produced during cell division. Cell division is a complex process that is regulated and checked at many points. Due to varying factors, the cell regulation mechanism may become non functional and this usually result in abnormal cell growth and division.
An abnormal cell growth may be cancerous or non cancerous. The best thing to do when one notices an abnormal growth in his body is to go and see the doctor. The doctors will administer appropriate test in order to determine the type of tumor that is present. If the tumor is non cancerous it will be removed by minor surgery. In case the tumor is cancerous, appropriate treatments will depending on the part of the body where it is found, the stage of growth and nature of the cancerous cells.

Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
Answer:
explanation below
Explanation:
A) Biodiversity is simply known as the number and variety of organisms found in a definite environment or region. Scientists have devised several ways of measuring biodiversity and the methods to be used depend on the type of organisms they are to count.
Canopy fogging – one of the ways of measuring biodiversity, has remained an effective way of obtaining details about the biodiversity of insects. It involves the act of spraying low dose of insecticides on a tree top, and when the insects fall from the trees, they are being collected on a large screen, that looks like a funnel.
Transact sampling is another way of measuring biodiversity and this time, with a transact line. The transact line is usually a measuring tape or rope that has been marked at set intervals.
b) Ecosystem stability is the ability of the ecosystem to maintain its steady state, even after it has experienced stress or disturbances. The biodiversity of an environment makes huge impact on the ecosystem stability in that particular area. It has been known that certain areas that have high levels of species and genetic diversity, are more likely going to an ecosystem that is complex, with varying food webs and biotic interactions. The increase in this complexity makes it more likely that the ecosystem of that area will rightly move back to a stable state whenever disturbances are experienced.
There are evaluated scientific evidence that shows that reduced biodiversity affects the transmission of communicable disease in agricultural crops, animals and humans. Loss of biodiversity usually increases susceptibility to diseases in plants and humans.
