Answer:
The answer is below
Explanation:
From the scientific and medical knowledge of human anatomy, placing aforementioned body structures in order of largest to the smallest, we have the following
1. muscles
2. fascicles
3. muscle fibers
4. myofibrils
Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.
(look, im not good at gammar, so you should get this looked at before entering it. I put it through gammarly if that helps.
Answer:
Phylogenetic (evolutionary) Tree
showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor.
• Each node is called a taxonomic unit.
• Internal nodes are generally called hypothetical
taxonomic units
• In a phylogenetic tree, each node with
descendants represents the most recent
common ancestor of the descendants, and the
• edge lengths (if present) correspond to time
estimates.
Explanation:
Phylogenetic trees are usually based on morphological or genetic homology. A comparison of anatomical traits can reveal an evolutionary relationship among species. Taxonomy, the science of classifying organisms, is based on phylogeny. Early taxonomic systems had no theoretical basis; organisms were grouped according to apparent similarity.
Most probably the right choice for this is <u>A. extraembryonic membranes</u> because this is known as the structural adaptation in chickens that allows them to lay eggs in arid environments rather than in water.
The four extraembryonic membranes that surround the chick's embryo are the chorion, which helps with gas exchange, the amnion, which encloses amniotic fluid, the yolk sac, which protects the yolk, and the allantois, which helps with waste removal and gas exchange.
Physical traits that have evolved on chickens through time in order to help them live and reproduce are called structural adaptations.
Over time, the hens that are more well-adapted to their surroundings survive and breed more consistently, causing their genes and adaptations to be passed down to future generations of chickens.
