From the vas deferens , the sperms move through the prostate gland to acquire the alkaline media to neutralize the vaginal environment ,then the sperms move to the urethra
Answer;
-Frequency
Explanation
-Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
-The speed of a wave is dependent on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency. Since speed is constant within the same medium, a high frequency has a short wavelength and vice-a-versa
Answer: Only options A, B, C and D are true statements
A) One sperm fuses with an egg while the other sperm fuses with the polar nuclei.
B) It results in the formation of a diploid embryo and triploid endosperm.
C) Both sperms involved in double fertilization form within the same pollen tube.
- The diploid nucleus resulting from the second fertilization undergoes meiosis to form the endosperm.
Explanation:
Double fertilization is a process that occurs in only flowering plants. It involves the following:
- A pollen grain produces TWO male gametes
- one male gamete fertilize the egg to form a zygote that is DIPLOID (with two basic sets of chromosomes)
- the second male gamete fuses with another cell named POLAR NUCLEI, to form endosperm (the food storing tissue) in the seed. The endosperm formed is TRIPLOID ( it has three sets of chromosomes), having undergone reductive division - meiosis
Thus, the options A, B, C and D are true statements
