Answer:
Egg
Explanation:
Reproductive system is the system of an organism encompassed with the function of giving rise to new offsprings. In sexual reproduction, which involves two organisms, one of the organisms is usually a MALE while the other is a FEMALE.
In most sexually reproducing organisms, the female reproductive system undergoes a division called MEIOSIS to produce a sex cell or gamete called EGG CELL. This egg cell gets fertilized by the sperm cell produced by the male to form a zygote. Hence, EGG CELL is the female reproductive system cell.
Answer:
The correct answer is - G and K.
Explanation:
Crossing over is the process that causes recombination by the genetic exchange in the nonsister chromatids of a homologous chromosome during the meiotic division in the cell.
The chances of the cross over in between two genes are directly proportional to the distance present in between the genes. The farthest the genes the chances of the crossover are more in these. So, there is in question the provided question has a chromosome with the greatest distance between G and K chromosome.
Thus, the correct answer is - G and K.
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.
Living things take in oxygen and take out carbondioxide . plants take that carbondioxide from atmosphere and gives out oxygen . thats why there is need to grow plants and trees.
