The bone labeled D in the diagram is the femur.
What is femur ?The femur is the longest and strongest bone in the human body, located in the upper leg or thigh. It articulates with the pelvis at the hip joint and with the tibia and fibula bones of the lower leg at the knee joint. The femur is responsible for supporting the body's weight, allowing for movement, and protecting the organs in the pelvic region.
The femur is divided into several sections, including the head, neck, shaft, and condyles. The head of the femur is a spherical structure that articulates with the acetabulum of the pelvis to form the hip joint.
The neck of the femur is a short section that connects the head to the shaft. The shaft of the femur is the long, straight part of the bone that extends from the neck to the condyles. The condyles of the femur are the rounded surfaces at the bottom of the bone that articulate with the tibia and fibula to form the knee joint.
The femur is composed of two types of bone tissue: compact bone and spongy bone. The compact bone is located on the surface of the bone and provides strength and protection, while the spongy bone is located in the interior of the bone and provides shock absorption.
Injuries to the femur can be serious and require medical attention. Fractures of the femur can occur due to high-impact accidents or falls, and may require surgery to repair.

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.

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.

what are three major lines of evidence that mitochondria arose from endosymbiosis with proteobacteria?
Answers
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
Answers
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.
