Can someone please do these for me? I’m feeling lazy.
1. How was the idea of natural selection developed? How does evolution by natural selection happen?
2. How does evidence of organisms having common ancestors support evolution?
3. What are some reasons organisms can go extinct?
4. Be able to describe how fossil evidence, embryology, and current examples of natural selection all support evolution.
5. How do humans and evolution affect each other?
1. (A) The theory of evolution by natural selection was developed by Charles Darwin in 1850. The theory was supported by his observations of the natural world during his five-year voyage from 1831 to 1836. (B) Evolution by natural selection happens when the environment changes, organisms best suited for the new environment survive and reproduce. The favorable adaptation is passed on to the next generation. Over time, more and more organisms will have a favorable adaptation, and the population will evolve.
2. Similar traits and features among various species can provide evidence of common ancestry. It is likely that traits and features shared by a group of organisms were inherited from a common ancestor.
Similar traits and features due to common ancestry are known as homology. By studying the homology of organisms, we can infer how they are related. The more similarities organisms share, the more closely related they likely are.
3. Habitat loss is the primary cause of higher extinction rates. Other causes include habitat changes, over-exploitation of wildlife for commercial purposes, the introduction of harmful nonnative species, pollution, and the spread of diseases.
4. Fossils are essential evidence for evolution because they show that life on Earth was different in the past than it is now. Paleontologists have used fossils to study the changes that have occurred in creatures as life has evolved on Earth. Embryology proves our modern theory of evolution by the similar structures found in embryos. The greater the similarity in structure, the more closely related the species are, and the more recent their common ancestor is. Natural selection is a mechanism that enables evolution. In a population with genetic diversity, the individuals that are better adapted and possess favorable traits eventually gain an advantage. Over time, the traits of these successful organisms dominate, causing the entire species to adopt these changes.
5. Every form of life on Earth interacts over time with other organisms, as well as with its physical environment. For that reason, the evolution of one species influences the evolution of species with which it coexists by changing the natural selection pressures those species face. The classic examples of this sort of evolution, called coevolution, are predator-prey and host-parasite relationships.

The endoderm, mesoderm, and ectoderm. Diploblastic organisms such as cnidarians and ctenophores only have two primary germ layers, the endoderm and ectoderm. The formation of the mesoderm layer is a characteristic of triploblastic organisms.
During fertilization, a diploid zygote is formed which undergoes a series of cell divisions called cleavage. This eventually leads to the formation of a blastula, which undergoes gastrulation to form the three primary germ layers. Coelom formation and metamorphosis occur later in development.
Therefore, during gastrulation, one should be able to distinguish between a diploblastic and triploblastic embryo based on the number of primary germ layers formed. However, the specific developmental stage may vary among different organisms.In diploblastic organisms, there are two germ layers (ectoderm and endoderm) formed, while in triploblastic organisms, three germ layers (ectoderm, mesoderm, and endoderm) are formed.

epinephrine is a positive chronotrope and inotrope. stimulation of which receptor is responsible for these properties?
Epinephrine is a hormone that acts as both a positive chronotrope and inotrope, meaning it increases heart rate and the force of contractions in the heart. The stimulation of beta-1 adrenergic receptors is responsible for these properties.
When epinephrine binds to beta-1 adrenergic receptors on the heart muscle cells, it activates a signaling cascade that results in increased calcium levels in the cells, leading to stronger contractions. This is the inotropic effect of epinephrine. At the same time, it also increases the rate at which the sinoatrial node (SA node) fires, which is responsible for initiating the electrical impulses that control the heart rate. This is the chronotropic effect of epinephrine.
The beta-1 adrenergic receptors are found predominantly in the heart, and the activation of these receptors is a key mechanism through which the sympathetic nervous system increases cardiac output in response to stress or exercise. However, epinephrine can also activate beta-2 adrenergic receptors, which are found in other tissues such as the lungs and blood vessels, resulting in bronchodilation and vasodilation respectively.

The best explanation for how higher concentrations of nitrogen and phosphorus contribute to eutrophication is that they stimulate the growth of algae, resulting in algal blooms.
Algae require nitrogen and phosphorus to build macromolecules, and when there is an excess of these nutrients in the water, the algae grow faster than they would normally. As the algae population increases, they consume more oxygen and create an oxygen-depleted environment that is not conducive to the survival of other aquatic species.
Additionally, as the algae die and decompose, the process consumes even more oxygen, further exacerbating the problem. This can lead to fish kills and the collapse of entire aquatic ecosystems. Therefore, it is important to manage and reduce the amount of nitrogen and phosphorus in our waterways to prevent eutrophication and protect the health of our aquatic ecosystems.

the acceptor stem is not critical for an aminoacyl-trna synthetase-trna interaction. (True or False)
False. The acceptor stem is critical for an aminoacyl-tRNA synthetase-trna interaction, as it contains the 3' end of the tRNA molecule where the amino acid is attached by the aminoacyl-trna synthetase.
The acceptor stem is a region located at the 3' end of a tRNA molecule that plays a crucial role in protein synthesis. Each tRNA molecule has a specific amino acid attached to it, and the acceptor stem is where the amino acid is attached to the tRNA molecule. The acceptor stem has a specific sequence of nucleotides that is complementary to the sequence of the codon on the mRNA that codes for the specific amino acid carried by the tRNA molecule. This complementary sequence ensures that the correct amino acid is attached to the tRNA molecule during protein synthesis. The attachment of the amino acid to the tRNA molecule is catalyzed by an enzyme called aminoacyl-tRNA synthetase. The enzyme recognizes the tRNA molecule through its acceptor stem and attaches the correct amino acid to the 3' end of the acceptor stem. This process is crucial for accurate translation of the genetic code from the mRNA molecule to the amino acid sequence in the protein. If the acceptor stem is altered, it could affect the ability of the aminoacyl-tRNA synthetase to attach the correct amino acid to the tRNA molecule, resulting in errors in protein synthesis.
