what are three major lines of evidence that mitochondria arose from endosymbiosis with proteobacteria?
Answer:Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria’s genome, but much smaller.
Explanation:
Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria’s genome, but much smaller.
The DNA, plasma membrane, and reproductive process are the evidence that supports the endosymbiotic theory of mitochondria.
What is endosymbiosis?Endosymbiosis is a process that includes the engulfing of one cell by another. It is said that mitochondria originated endosymbiotically from proteobacteria.
The presence of the mitochondrial DNA although small shows similarity to bacterial DNA. The mitochondria are membrane-bound organelle like the prokaryotic bacteria.
The reproductive process of mitochondria resembles the bacterial reproduction method. The cytoplasm and the genetic material are divided in a similar fashion.
Therefore, DNA, reproduction, and membrane are evidence of the Endosymbiotic origin of mitochondria.

A bird-watcher sees a small yellow bird in a tree. Explain to the bird-watcher how he can use a dichotomous key to identify the bird. Assume he does not know anything about dichotomous keys. Then, write two steps of a dichotomous key that would be helpful for the bird-watcher.(2 points) PLS HURRY WILL GIVE BRAINLIEST
A dichotomous key is a classification tool based on morphological or behavioral characteristics. It provides two options per feature.
What is a dichotomous key?A dichotomous key is a significantly useful tool to classify organisms.
If you have an organism -or part of it- and you need to taxonomically identify it, you use a dichotomous key.
The key provides an easy and fast way for identification by describing different morphological or behavioral traits, leading you to the correct taxonomic classification.
The term dichotomous refers to how information is provided.
You will always have two options per feature (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.
Once you choose one of the options according to your organism, the key leads you to the following description, and you will have to choose one of the options again.
You will repeat this until you reach the name of your organism.
The key describes only specific traits that are useful for differentiation.
Now, let us write two steps of a dichotomous key that would be helpful for the bird-watcher.
Description 1a ----------- The organism is a vertebrate ----------- Go to 2
Description 1b------------ The organism is invertebrate ----------- Go to 5
Description 2a ---------- The organism flies ----- Go to 3
Description 2b ---------- The organism does not fly ---------- Go to 4
Description 3a ------ The organism is yellow and sings ---- This is your bird
Description 3b ----- The organism is grey and does not sing --- This is another bird
So in this example, the key asks you if the animal you are looking at is a vertebrate or not. It is a vertebrate, so you choose option 1a and move to description 2.
In description 2 the key asks you if your animal flies or not. It is a bird and is on a tree, so does it fly. You choose option 2a and move to description 3.
Finally, the key asks you if your bird is yellow and sings or if it is grey and does not sing. You choose option 3a and the key tells you the name of your bird.

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
A man who heavily smokes has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, making them unable to stop reproducing and dividing. He is worried that his children, none of whom smoke, may have inherited the lung cancer from him. Under what circumstances might his concern for his children be justified? If his smoking had already mutated the DNA in the cells in his lungs at the time his children were conceived, the mutations would have been passed to his children. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children. If the mutation resulted from the duplication of a gene in his lung cells, his children would be at greater risk than if it were caused by a base pair substitution. If the smoke had caused multiple different mutations in his lung cells, it would be more likely that one or more of the mutations would be passed to his children.
If he inherited a mutation that made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children is the circumstance that might his concern for his children be justified.
What do you mean by Mutation?A Mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.
Gametes of germline cells play an important role in the inheritance of mutation from parents to their offspring, which means that if a mutation has occurred in an egg or sperm cell, it will be more chances that the offspring carry mutated DNA.

Please help me out guys
Answer:
a device for collecting and measuring rain as it falls
Weather radar is a vital instrument for observing the atmosphere to help provide weather forecasts and issue weather warnings to the public. The current Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage to most regions of the United States (NRC, 1995). This network was designed in the mid 1980s and deployed in the 1990s as part of the National Weather Service (NWS) modernization (NRC, 1999). Since the initial design phase of the NEXRAD program, considerable advances have been made in radar technologies and in the use of weather radar for monitoring and prediction. The development of new technologies provides the motivation for appraising the status of the current weather radar system and identifying the most promising approaches for the development of its eventual replacement.
The charge to the committee was to determine the state of knowledge regarding ground-based weather surveillance radar technology and identify the most promising approaches for the design of the replacement for the present Doppler Weather Radar. This report presents a first look at potential approaches for future upgrades to or replacements of the current weather radar system. The need, and schedule, for replacing the current system has not been established, but the committee used the briefings and deliberations to assess how the current system satisfies the current and emerging needs of the operational and research communities and identified potential system upgrades for providing improved weather forecasts and warnings. The time scale for any total replacement of the system (20- to 30-year time horizon) precluded detailed investigation of the designs and cost structures associated with any new weather radar system. The committee instead noted technologies that could provide improvements over the capabilities of the evolving NEXRAD system and recommends more detailed investigation and evaluation of several of these technologies. In the course of its deliberations, the committee developed a sense that the processes by which the eventual replacement radar system is developed and deployed could be as significant as the specific technologies adopted. Consequently, some of the committee's recommendations deal with such procedural issues.
