Typically, higher order streams contain MORE water than lower order streams.
Stream ordering is a mean of classifying natural channels in a water shed based on their sizes. The first order stream is the smallest stream and the second order stream is bigger than the first. Thus, the amount of water in the first order stream will be less that that of second order.<span />
Answer:
The correct answer is a. Seminal vesicle
Explanation:
Seminal vesicles are the pair of glands that are found in the male pelvic region below the urinary bladder. Seminal vesicles produce about 60% of fluid present in the total semen ejaculate therefore without seminal secretion semen would be very low in volume.
The seminal fluid contains nutrients like fructose that provide energy to the sperms, phosphorus and potassium that helps in the motility of sperms. Seminal fluid is alkaline in nature which protects sperms from the acidic environment in the vagina. Therefore the correct answer is a. Seminal vesicle.
<span>Conducting a monohybrid cross of F1 generation plants, the recessive trait reappears in F2 plants in a ratio of 3:1. Let allele A be dominant, and allele a be recessive. Genotypes (and their phenotypes) will be: AA (dominant trait), Aa (dominant trait), aa (recessive trait). In F1 generation, all plants are heterozygotes Aa. After they cross (Aa x Aa), the offspring will be as following: AA (dominant trait), Aa (dominant trait), Aa (dominant trait), and aa (recessive trait). So, there will be 3 plants with dominant traits and one plant with recessive trait.

Genetic variation within chromosomes has increased. Now, more combinations of the of the DNA exist and they are now more genetically diverse.
