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.
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!.

C. It is written as kingdom and phylum.
D. It is written with quotation marks around it.
Answer:
the right option here is option C
The statement which describes how the scientific name of an organism is written is—It is written as genus and species. Therefore, the correct option is B.
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.

Questions and Conclusion 1. If the egg is a model of Earth, what does each part of the egg represent? (Use the chart below.)
Portion of Egg Part of the Earth It Represents
Whole egg
Egg shell
Cracked pieces of egg shell
Egg white
Egg yolk
2. How does your model demonstrate the differences between the types of tectonic plates and the resulting observations in the asthenosphere?
3. How did your hypotheses of your Tectonic Egg Model compare to your experimental results?
4. What are some shortcomings of using this model as a replicable of the Earth? Suggest a way that a scientist could create a more accurate model of Earth’s tectonic plates.
Answer:
the egg yolk is the Earth's inner core
the egg white is Earth's outer core
the egg shell is the mantle
the cracked pieces of egg shell is the lithosphere
the entire egg is earth
Explanation:
I'm not sure about all of these, but it should hopefully be correct. I'm not sure about what the whole egg would be. I hope this helps you anyways :)
Here is a possible interpretation of what each part of the egg represents in the Tectonic Egg Model:
Egg shell: represents the Earth's crust, which is the outermost layer of the planet that consists of solid rocks and varies in thickness from about 5 km to 70 km.
Cracked pieces of egg shell: represent the boundaries between tectonic plates, where earthquakes and volcanic eruptions often occur due to the movement and interaction of the plates.
Egg white: represents the asthenosphere, which is a partly molten layer beneath the crust that behaves like a plastic material and allows the plates to move and slide.
Egg yolk: represents the Earth's core, which is the central part of the planet that consists of a solid inner core and a liquid outer core, and generates the Earth's magnetic field.
What does the Tectonic Egg Model can demonstrate ?the differences between the types of tectonic plates and their resulting observations in the asthenosphere by using different colors or types of egg shells to represent different plate types (e.g., oceanic vs. continental) and by observing how they interact and move relative to each other in the egg white layer.
For example, oceanic plates are denser and tend to sink beneath continental plates at subduction zones, whereas continental plates are thicker and tend to form mountain ranges when they collide.
The hypotheses of the Tectonic Egg Model could be tested by observing how the egg shells move and interact with each other when the egg is shaken or rotated, and comparing the results to the expected behaviors based on the types of plates and the properties of the asthenosphere.
If the model is too simplistic or inaccurate, the experimental results may not match the expectations or observations of real-world tectonic activity.
Some shortcomings of using the Tectonic Egg Model as a replicable of the Earth include:
The egg is much smaller and simpler than the Earth, so it cannot capture the full complexity and scale of tectonic processes.
The egg shell is brittle and does not behave like real rocks, which can deform and change over time due to pressure, temperature, and chemical reactions.
The egg yolk may not represent the Earth's core accurately, as it does not have the same density, composition, or behavior as the real core.
To create a more accurate model of Earth's tectonic plates, a scientist could use computer simulations or physical experiments that involve more realistic materials and conditions, such as:
Using a sphere or globe that approximates the size and shape of the Earth, and using different layers of materials (e.g., clay, sand, water, oil) to represent the crust, mantle, and core.
Using a rheometer or other mechanical device that can apply controlled forces and stresses to the materials, and measure their deformation and response over time.
Using sophisticated computer software that can simulate the behavior of tectonic plates and their interactions based on known physical laws and data from real-world observations (e.g., GPS, seismology, satellite imaging).

The strangler fig’s roots grow up and down the host tree, it latches onto. These roots eventually grow high enough to reach the sunlight in the cloud forest. Typically, after this happens the host tree eventually dies, leaving a hollowed-out center wrapped in large roots. What type of tropism is responsible for the hollowed-out tree? Explain your answer.
Answer:the relationship between host tree and strangler fig may be more mutually beneficial than previously thought, in a symbiosis where the host provides a structure to support the strangler fig's establishment in the well-lit canopy, and the strangler fig helps to support its host during storms
The aerial roots of strangler figs may attach to surrounding vegetation on the ground, stabilising the host plant and making it less likely to become uprooted. The leaves of the fig may also help shield from wind by closing up the forest canopy. Geotropism
Which cells are more common in the human body, germ cells or somatic cells?
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

The Virginia Meadowsweet, a plant native to the wetlands of Georgia, is the primary food source for the larvae of the Spring Azure Butterfly. The Virginia Meadowsweet plant population is becoming endangered due to the clearing of the wetlands for farming and construction. Many environmentalists claim that this disturbance will affect other populations in the ecosystem.
Which argument BEST supports the environmentalists’ claim?
A.
As the Virginia Meadowsweet plant population decreases, the butterfly population will decrease because the larvae will not have enough food to sustain their current population.
B.
As the Virginia Meadowsweet plant population decreases, the butterfly population will increase because the larvae will not have enough food to sustain their current population.
C.
As the Virginia Meadowsweet plant population decreases, the butterfly population will increase because the butterflies’ predators are being killed off as more land is cleared.
