Wheat production W in a given year depends on the average temperature T and the annual rainfall R. Scientists estimate that the
Nimfa-mama [501]

Answer:

-1.1

Explanation:

Data provided in the question:

Average temperature is rising at a rate, \frac{dT}{dt} = 0.15°C/year

Rate of change  rainfall, \frac{dR}{dt} = - 0.1 cm/year

\frac{\delta W}{\delta T} = -2

\frac{\delta W}{\delta R} = 8

Now,

we need to calculate \frac{dW}{dt}

since,

The wheat production (W) is dependent on the rainfall (R) and the Temperature (T)

thus, Using the chain rule , we have

\frac{dW}{dt} = \frac{\delta W}{dT}\times\frac{dT}{dt} +  \frac{\delta W}{dR}\times\frac{dR}{dt}

on substituting the respective values, we get

\frac{dW}{dt} = -2 × 0.15 +  8 × (-0.1)

or

\frac{dW}{dt} = -0.3 - 0.8

or

\frac{dW}{dt} = -1.1

Begin at the ovaries of susie and the testes of billy.track the processes of ovulation for susie and ejaculation of billy.
Shkiper50 [21]

Ovulation and ejaculation are the processes that involve the release of the female and male gamete  for the process of fertilization.

<u>Ovulation</u>

  • The release of an egg from one of a woman's ovaries is known as ovulation.
  • Ovulation usually lasts for one day and takes place two weeks before a woman anticipates getting her period, in the midst of her menstrual cycle.
  • However, the procedure takes a different amount of time for every woman, and it might even change from month to month.
  • A sperm cell can fertilize an egg when it exits a woman's ovary and enters the fallopian tube.
  • Sperm can survive for three to five days inside a woman's reproductive system.
  • The uterine walls thicken during ovulation in order to accommodate a fertilized egg. On the other hand, if the egg is not fertilized, the uterine lining is lost around two weeks later, which results in menstruation.

<u>Ejaculation</u>

  • Ejaculation, the male reproductive system's discharge of sperm cells and seminal plasma.
  • Sperm are transported from the testicles and the epididymis, where they are stored, to the beginning of the urethra, a hollow tube that runs through the pen!s and transports either sperm or urine.
  • In the second stage, known as the actual ejaculation, the semen is transported through the urethra and expelled from the body.

How is the circulatory system related to the digestive system??
Papessa [141]
The products of the digestive system are actually tied directly to the circulatory system in that the organs of the digestive system are used to turn ingested food into products that can be absorbed by the blood and then carried to other organs for use as energy or other functions.There are also several links between the digestive system and the respiratory system in that there are organs and muscles that serve both, for example the diaphragm which works to force air into and out of the lungs as well as to force waste products out of the digestive system.<span>All of the systems have to work together as well, without the intake of oxygen and exhalation of carbon dioxide, the function of the digestive system would grind to a halt.  Without the production of glycogen and other things necessary for muscular function, produced by the digestive system and then distributed by the circulatory system, all three functions would cease.</span>
