What is a scientific name of an organism?

Scientific names are the names that are given to a species of an organism, which is based on the binomial nomenclature given by  Swedish botanist Carolus Linnaeus. These names are given by the taxonomists while naming an organism at the species level.

A scientific name comprises 2 parts: The first part is the genus name or the generic name, while the second part is the name of the species. A third part can also be added, where the name of the scientist who first discovered the species is written. Example- Homo sapiens refers to modern human beings. It is written in italics and in which the initial letter of the genus name is capitalized. Therefore, the correct option is B.

1.) describe the amphibian life cycle. Include the different phases and traits of each phase.
2.) describe how baby reptiles are born and what they are like.

Answers

Answer:

1.) The Amphibian life cycle isn't as simple as it seems. The main Amphibian that has a longer process are called Frogs. Everyone knows frogs, but they are different from most animals such as turtles. The first stage of frogs are when their in eggs of course. These eggs are called "Tadpoles" and look different than most eggs. These eggs are kept in water until they grow. Which brings me to the next stage. When the tadpoles hatch you would start to see something like a baby fish swimming around. That's still the same tadpoles you saw before just hatched. When it comes to this topic most are confused because frogs don't have tails. Well during these stages a tail is used to help them survive in the water and move around. The third stage of these interesting creatures are when they grow legs. That's when they are able to walk on land. They still have their tail of course. It still helps them swim in water. I don't understand much about why they still have a tail if they've grown legs,  but that's for me to find out soon. Eventually they grow more and more and get better with their legs and lose the tail. Well the tail doesn't just magically disappear. It's actually absorbed  by using something called apoptosis. Then it's pretty much and adult frog.

2.) Most baby reptiles are grown in eggs. Another name for them would be "Amphibians". These little creatures are mostly kept in water or hidden underground for various reasons. Unlike turtles and lizards. Frog eggs are called "Tadpoles". They look like mini clear eyes. They also have a longer process than most animals which was explained in the first question!.

Which cells are more common in the human body, germ cells or somatic cells?

Answers

Answer:

Germ cells are highly specialized cells that form gametes, and they are the only cells within an organism that contribute genes to offspring. Germline stem cells (GSCs) sustain gamete production, both oogenesis (egg production) and spermatogenesis (sperm production), in many organisms. Since the genetic information contained within germ cells is passed from generation to generation, the germ line is often referred to as immortal. Therefore, it is possible that germ cells possess unique strategies to protect and transmit the genetic information contained within them indefinitely. On the other hand, it was shown that germ cells are pluripotent in all stages of development. We and other groups succeeded in the long-term culture of spermatogonial stem cells (SSCs) of mice. The cells were phenotypically similar to the ES/embryonic germ cells except for their genomic imprinting pattern. They differentiated into various types of somatic cells in vitro under the conditions used to induce the differentiation of the ES cells, and the SSCs formed germline chimeras when injected into blastocysts. Furthermore, we have shown that somatic stem cells are able to differentiate to germ cells. Derivation of both male and female gametes in vitro raises the possibility of using these gametes to gain a better understanding of basic reproductive biology and, in particular, to extend the potential for therapeutic cloning, transgenic technologies and the treatment of infertility. We started three different approaches for establishment of the in vitro gametogenesis systems: 1) ES-derived gametogenesis, 2) derivation of germ cells from somatic stem cells and 3) in vitro gametogenesis based on cultured spermatogonial stem cells. We developed a strategy for the establishment of germline stem cell lines from embryonic stem cells. These cells are able to undergo meiosis, generate haploid male gametes in vitro and are functional, as shown by fertilization after intra-cytoplasmic injection into mouse oocytes. Molecular and cellular mechanisms underlying differentiation of ES to functional gametes should be elucidated in future research. In other approach, we show that bone marrow stem (BMS) cells are able to trans-differentiate into male germ cells. BMS

"Somatic cells" is a fairly general term which refers to essentially all the cells of the body except for the germ line; the germ line being the cells in the sexual organs that produce sperm and eggs.

Which statement below best describes how energy flows in a food chain or food web?

Answers

Flows to one or more levels of consumers

The energy  flows in a food chain or food web from the plants to the consumers and the decomposer, with a 10% reduction in energy flow from one to the other as the rest of the 90% is used by the organism.

What is the significance of the energy flow in the food chain or food web?

Energy flows from one trophic level to another in a food chain or food web because not all of it can be used and some is lost as heat during each transfer from one organism to another. In this way, the plants make the energy in the form of food that is later consumed by the consumer and goes into the nutrient cycle.

Hence, energy flows in a food chain or food web from the plants to the consumers and the decomposer, with a 10% reduction in energy flow from one to the other as the rest of the 90% is used by the organism.
