Classify the organisms based on whether they follow the Camegie stages of development
The correct answer is that a butterfly and an octopus do not have Carnegie stages of development, while elephants and turtles do. This is because Carnegie stages of development are stages found only in the development of the vertebrate embryo. Carnegie stages can be defined as a system in embryology, which include 23 stages of the embryonic development, each characterized with the different age, size and morphologic characteristics of an organism.
Organisms in the animal kingdom are classified based on their body morphology, developmental pathways, and embryological development. The Carnegie stages of development refers to the classification of human embryos based on their physical and internal features at different stages of development.
Explanation:Classifying Organisms by their Developmental Stages
Organisms in the animal kingdom are classified based on their body morphology, developmental pathways, and embryological development. The Carnegie stages of development specifically refer to the classification of human embryos based on their physical and internal features at different stages of development.
For example, the Carnegie stages can help identify when specific organ systems start to form or when major developmental milestones occur. However, it's important to note that the Carnegie stages are specific to human embryonic development and may not be applicable to all organisms in the animal kingdom. Other organisms may have their own unique classification systems based on their own specific developmental characteristics and stages.

Which of these could increase average global temperatures?
Answer:
Burning fossil fuels, over harvesting of petroleum.
Explanation:
If you cold attach the answers, I can give you a better answer.
The increase average global temperatures D Setting more factories . Therefore , D Setting more factories is correct.
The primary mechanism through which this occurs is the emission of greenhouse gases (GHGs) during industrial processes.
Factories often burn fossil fuels, such as coal, oil, and natural gas, for energy. Combustion of these fuels releases carbon dioxide (CO2), a major greenhouse gas, into the atmosphere.
Additionally, industrial activities may release other GHGs like methane (CH4) and nitrous oxide (N2O).
These gases trap heat in the Earth's atmosphere, leading to a gradual warming known as global warming.
Furthermore, some industrial processes release particulate matter and aerosols into the atmosphere.
While these particles can have a cooling effect by reflecting sunlight back into space, their impact is generally outweighed by the warming effect of greenhouse gas emissions.
The industrial sector also contributes to deforestation for resource extraction and infrastructure development.
Deforestation reduces the number of trees, which act as carbon sinks by absorbing CO2 during photosynthesis.
The loss of these carbon sinks intensifies the greenhouse effect.
Efforts to mitigate the impact of industrial activities on global temperature involve adopting cleaner technologies, improving energy efficiency, and transitioning to renewable energy sources.
Recognizing and addressing the environmental consequences of industrialization are crucial steps in mitigating climate change and promoting sustainable development.

Which statement best explains why obsidian has a smooth glassy surface but basalt has a rough surface? Obsidian is formed due to compaction and basalt is formed due to weathering. Obsidian allows less crystal growth than basalt because it cools more rapidly than basalt. Basalt is more easily eroded than obsidian because it is formed at a lower temperature than obsidian. Basalt is formed from the erosion of sediments and obsidian is formed due to the metamorphosis of rocks.
Answer:
Obsidian allows less crystal growth than basalt because it cools more rapidly than basalt.
Explanation:
Both Obsidian and Basalts are igneous rocks. Igneous rocks from the solidification and cooling of magma.
The textures of igneous rocks relies mostly on their mode of formation. Igneous texture refers to the way minerals are formed and arranged in rocks.
When magma forms and cools rapidly, crystals of minerals don't have time to grow. This leads to the formation of a rock that would look like glass. An example of such rock is Obisdian. Obsidian's glassy and smooth texture is as a result of the way it was formed. This rock type is an extrusive igneous rock that forms on the surface where cooling magma solidifies rapidly and crystals have little to no time to solidify.
Basalt on the other hand is an extrusive igneous rock. The mineral grains here have some ample time to form. Basalt is made of mafic minerals which impacts some very interesting textures on the rock mass. The texture of a typical basalt is fine grained and the minerals can be seen when magnified. Cooling is not as rapid during the formation of basalts compared to obsidian.

Order the steps of protein synthesis,
Answer: Hola! My name is Marissa and im here to help !:) don't hesitate to give brainliest!
step1-start of synthesis
step2-initiation
step3 -elongation
final- elongation and termination
The first step in protein synthesis is the transcription of mRNA from a DNA gene in the nucleus.
before the protein synthesis, all of the component parts are assembled in the ribosome
step 2
In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine
step 3
Elongation of the peptide begins as various tRNA's read the next codon. In the example on the left the next tRNA to read the mRNA is tyrosine. When the correct match with the anticodons of a tRNA has been found, the tyrosine forms a peptide bond with the growing peptide chain .
step 4
When the stop signal on mRNA is reached, the protein synthesis is terminated. The last amino acid is hydrolyzed from its t-RNA.
Explanation:
Protein synthesis : It is a procedure in which cells make protein.
There are two stage of protein synthesis.
1): Transcription
2): Translation
The transfer of genetic instruction in DNA to mRNA in the nucleus is called transcription. Transcription include three steps:
a) initiation b) elongation and c) termination.
After the mRNA is managed it carries the command to a ribosome in the cytoplasm.
Translation happen at the ribosome in which contain rRNA and proteins. In a translation the command mRNA are read and tRNA gives the true order of amino acids to a ribosome. after that rRNA helps bonds structure between the amino acids, construct a polypeptide chain.
Then a polypeptide chain is combined it may undergo further processing to form the finished protein.
