Answer #1

Answer - A corpus lutea is the vacant spot occupied previously by an ovum within the ovary, now filled by a yellow body that is clearly not an ovum. Degenerated corpus lutea means whatever was there get replace. The spot that once held the egg has now decomposed somewhat, and you have a total misrepresentation of a potential litter offspring.

These are spots filled with some type of glandular liquid, but are hardly the genetic material needed for the production of healthy, viable offspring. It would be more accurate to count only the existing ova available for fertilization then to calculate the number of litter.

1) The decomposition of litter and the subsequent release of nutrients in plant-available forms are essential to maintaining healthy forest ecosystems. Thus, knowledge of factors affecting decomposition rate becomes extremely important in forest management and conservation. a.) Would you expect decomposition rates to be the same throughout an area (e.g. extending from a coastal habitat, through the mountains, to interior habitats). Why? b.) Under the same environmental circumstances (e.g. for trees found in the same geographic area), would you expect...

A preliminary measurement made during a short counting time suggested a gross counting rate of 55 cpm. The background counting rate, determined by a 1-h measurement, is 25 cpm. How long should the sample be counted in order to be 96% certain that the measured net counting rate will be within 10% of the true counting rate?

I hate changing the cat litter. Even with regular scoopings, if I don't completely change the litter at least once every 15 days, it stinks. A scientist has invented a new cat litter she proposes will last more than 15 days. A sample of the new cat litter is placed in 49 different homes. The average effectiveness of the new cat litter is measured to be 16.2 days. For the population of all cat litters in the market, the standard...

The Reno City Council has passed a law requiring litter to be reduced by 108 pounds per day. The city can reduce litter near UNR campus (C), near downtown Reno (D), or both. The marginal abatement cost for campus is MAC_C=0.05A_C and the total abatement cost equation is TAC_C=0.025A_C^2. The marginal abatement cost for downtown is MAC_D=0.13A_D and the total abatement cost equation is TAC_D=0.065A_D^2 In each area, how much litter should be abated to meet the city's requirements at...

The Reno City Council has passed a law requiring litter to be reduced by 108 pounds per day. The city can reduce litter near UNR campus (C), near downtown Reno (D), or both. The marginal abatement cost for campus is MAC_C=0.05A_C and the total abatement cost equation is TAC_C=0.025A_C^2 . The marginal abatement cost for downtown is MAC_D=0.13A_D and the total abatement cost equation is TAC_D=0.065A_D^2. Is the uniform policy of equal reduction cost-effective? Justify your answer.

In a population of rabbits the mean number of rabbits born in a litter is unknown, but the standard deviation is 1.64. In a sample of 300 rabbits a sample mean of 6.7 rabbits per litter was obtained. Determine a 95% confidence interval. a) We have 95% confidence that the interval, 4.74 rabbits < μ < 8.66 rabbits will contain the mean number of rabbits born in all litters. b) We have 95% confidence that the interval, 6.51 rabbits <  μ  <...

A program to reduce littering was introduced in Brisbane in August 2011. The amount of litter collected off the streets of six suburbs (average kilograms of litter per block per day) was measured during July 2011 before the program started and then again in July 2012 after the program had been in effect for one year. The results are as follows: Suburb July 2011 July 2012 Difference Diff. – M Deviation2 New Farm 9 2 Gap 10 4 Spring Hill...
