equilibrium populations. Provide one example of each. Opportunistic species use the “r-strategy”. “r” is the species instrinsic rate of increase. They produce millions of eggs and sperm since only a small percent will then meet, join and become actual offspring. Example : most insects, corals , scallops , oysters and clams that fertilize their eggs in the water. Opportunistic species are often the first to colonize a new environment and their population growth is exponential. Equilibrium species use the “k-strategy”

Picture a crowded hallway in your school between classes. People are rushing to class, locker doors are being flung open and slammed shut, and a girl is opening the door to the Girls' room. Now freeze on that mental picture. Which of the following choices is a good description of you in that picture? I'm the girl going into the Girls' room, and I'm giving my friend a look across the hall that means, "Ugh - I'm going to change my pad (or tampon), and I'll see you later." I've got cramps, and right

Plasma membrane: The plasma membrane controls how substances move in and out of the cell. The cell membrane contains phospholipids, proteins and carbohydrates. These are arranged in a fluid mosaic structure. Cytoplasm: The cytoplasm is everything that is outside the nucleus and inside of the cell membrane. The fibre network helps maintain its shape and gives it support. Nucleus: Nucleus contains the DNA and is like a brain Ribosome: Ribosomes contain and give out the protein. They connect

What is RH Law? The Responsible Parenthood and Reproductive Health Act of 2012 (Republic Act No. 10354), informally known as the Reproductive Health Law or RH Law, is a law in the Philippines, which guarantees universal access to methods on contraception, fertility control, sexual education, and maternal care. How does RH Law started? According to the Senate Policy Brief titled "Promoting Reproductive Health", the history of reproductive health in the Philippines dates back to 1967 when

and start consuming it. 2. Opportunistic species use the “R-strategy”, where R= the species’ intrinsic rate of increase. They produce millions of eggs and sperm since only a small percent will actually meet, join, and become offspring. Examples are most insects, and corals, barnacles, clams, scallops and oysters, who spawn and fertilize their eggs in the water. Opportunistic species are often the first to colonize a new environment and their population growth is often exponential. They tend to

the spermatozoa travel through the cervix and body of the uterus and into the Fallopian tubes. Fertilization of the ovum (egg cell) usually takes place in the Fallopian tube. Many sperm must cooperate to penetrate the thick protective shell-like barrier that surrounds the ovum. The first sperm that penetrates fully into the egg donates its genetic material (DNA). The egg then polarizes, repelling any additional sperm. The resulting combination is called a zygote, a new and genetically unique human organism. The term

course of evolution. They came up with various theories that explain the problem of comparison. The modes of Reproduction in wasp are different both in genetic difference and individual difference. “Females develop from fertilized eggs and makes from unfertilized eggs. I n sexual populations, females only produce daughter without fertilization” according to the Science Daily article by C. Vorburger. Using cross experiments, the traits that are inherited are recessively and traits that act like a

different techniques of mitochondrial replacement therapy, an example would be pronuclear transfer. This method entails the egg of the mother and donor egg being fertilized, using the father’s sperm in vitro, producing two zygotes. Both zygotes are left to develop until a very early zygotic stage where the pronuclei are still visible. At this point the zygote formed, from the donor egg, will have its nuclear material discarded as a karyoplast and the nuclear material from the parents’ zygote is transferred
