Detail how the dorsal: ventral axis is established in amphibia, from the
importance of the sperm entry point to the gene regulation in the dorsal area of the entryo
Answer:
Explanation: Amphibian axis formation is an example of regulative development. The most important clue came from the fate map of this area of the egg, for it. Therefore, the specification of the dorsal-ventral axis begins at the moment of sperm entry. The Siamois protein is critical for the expression of organizer-specific genes

Living things are mostly made up of four elements: carbon, hydrogen, nitrogen, and oxygen. Describe how plants and animals obtain these elements.
Answer:
Explanation:
Animals obtain carbon by eating and gaining nutrients. This gives them carbon. They get hydrogen by water and glucose. They get nitrogen from food.
Animals obtain these essential elements through the consumption of food and water on basis of their mode of nutrition. While plants directly synthesize these elements with the help of the process known as photosynthesis.
What are the roles of these four elements?Carbon is considered the building block of living creatures. While other elements like oxygen, nitrogen, and hydrogen are also required by these living entities in order to complete their life cycle, perform growth and development, energy synthesis, metabolism, etc.
The process of obtaining these essential elements in plants and animals differs a lot. This is because the mode of nutrition for both living entities varies.
Plant being autotrophs synthesize their food through photosynthesis and takes essential nutrients from the soil. On contrary, animals get these elements by eating other animals or plant-derived products.

Agriscience: What are some of the advancements in fertilizer that was created by Florikan and by Suprasensor?
Answer:
Florikan developed polymer coated controlled - release fertilizer and Suprasensor developed soil sensors.
Explanation:
Florikan developed polymer coated controlled - release fertilizer which are fertilizers which gradually release their nutrients into the soil for plant use, while Suprasensor developed soil sensors which detect the presence of pesticides, fertilizers and other agricultural chemicals and prescribe soil salinity level which allow farmers to solve unmet needs while detecting and monitoring critical molecular components while cultivating.

Which of the following is a
process that organisms use
to combine two cells to
create one cell, thus
creating a new organism?
A. Asexual reproduction
B. Sexual reproduction
C. Mitosis
D. Somatic cells
Answer:
B. Sexual reproduction
Explanation:
Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).
In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.

A)Only larger countries impact greenhouse gas levels on a global scale.
B) Less developed countries have equivalent greenhouse gas emissions to industrialized nations due to their reliance on burning biomass for fuel.
C) The United States has a smaller population than China, but has a higher per capita greenhouse gas emission, resulting in a larger carbon footprint on a national level.
D) Although the United States and China are roughly the same geographical size, the United States must have a larger population of citizens to result in a higher level of greenhouse gas emissions.
Answer:
C) is correct
Explanation:
The United States has a smaller population than China, but has a higher per capita greenhouse gas emission, resulting in a larger carbon footprint on a national level.

What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?(this is for gizmos lab carbon cycle)
Answer: When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere.
9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.
What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?According to the Intergovernmental Panel on Climate Change, the average annual increase in carbon dioxide concentration from 2000 to 2009 was about 1.9 parts per million (ppm) per year, of which about 55% came from the burning of fossil fuels and industrial processes, and about 45% came from land-use change, primarily deforestation.
Thus, in terms of actual amounts, this translates to roughly 9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.
