Answers
Fast emus will survive longer and reproduce more and eventually most of the population will become fast which is referred to as descent of modification and is a true statement.
What is descent with modification?This is referred to as the process in which different types of traits are passed down from generation to generation and in some cases undergo changes or modifications over time.
These different modifications are usually caused by natural selection or mutation in the DNA of the organism which in this case makes the organism to run faster and escape from predators which is therefore the reason why it was chosen as the correct choice.

Answers
It is the folds and structure of amino acids that determines the shape and function of a protein.
What are amino acids?
Both as the building blocks of proteins and as metabolic intermediaries, amino acids perform crucial functions. Proteins include 20 amino acids, which offer a wide range of chemical diversity. A given protein's exact amino acid composition and amino acid sequence are defined by the bases in the gene that codes for that protein. The biological activity of a protein is determined by the chemical characteristics of its amino acids.The information needed to predict how a protein will fold into a three-dimensional structure and the stability of the resultant structure is also contained in the amino acid sequences of proteins. Since many years ago, the study of protein folding and stability has been of utmost importance. It is still one of the world's greatest mysteries. But research into it is ongoing, and daily advancements are being made.What are proteins?
The body is made up of protein, which may be found in almost every organ, tissue, and body component, including muscle, bone, skin, and hair. It contributes to the production of hemoglobin, which transports oxygen in the blood, and enzymes, which drive numerous chemical processes. Twenty-plus fundamental building components known as amino acids are used to create protein. Our bodies produce amino acids in two distinct ways since we cannot store them: either from scratch or by altering existing ones. The essential amino acids, also known as histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, must be obtained from diet.Hence, the folds and structure determines the shape and structure of protein.

is the entire zygote involved in early cleavage? what evidence to you have to support your answer?
Answers
Yes, the entire zygote is involved in early cleavage.
Evidence to support this statement includes the following:
Definition of cleavage: Cleavage is the process of cell division that occurs after fertilization, where the zygote divides into multiple cells called blastomeres. Since cleavage involves the division of the zygote, the entire zygote is involved in this process.Purpose of cleavage: The primary purpose of cleavage is to increase the number of cells without increasing the overall size of the embryo. This is achieved by the entire zygote dividing into smaller cells.Uniformity of blastomeres: During early cleavage, the blastomeres are generally similar in size and appearance. This uniformity suggests that the entire zygote is involved in the cleavage process.Holoblastic cleavage: In many animals, including mammals, the zygote undergoes holoblastic cleavage. This type of cleavage involves the complete division of the entire zygote, providing further evidence that the whole zygote is involved in early cleavage.In conclusion, the entire zygote is involved in early cleavage, as supported by the definition of cleavage, its purpose, the uniformity of blastomeres, and the occurrence of holoblastic cleavage in many animals.

A parasitic organism is that which derives nutrients from another, usually called a host, by harming it. In this case of Arainne who fell sick after traveling abroad and eating different countries' food, it indicates that a microbe that is harming her (leading to health complications) has contaminated her food.
Contrary to a parasitic organism, a mutualistic and commensalistic organism will not cause harm to any organism they interact with. Only a parasite will deteriorate the health and physical well being of its host in the process of obtaining nutrients. A predatorial organism kills its pretty, which is not the case here.
Therefore, Arianne's current health condition is as a result of the contamination of the food she ate by a parasitic bacteria.

nitrogenous wastes like ammonia and urea build up.
ATP cannot be made from protein.
proteins contain 9kcal/gram.
Answers
Protein metabolism is difficult because nitrogenous wastes like ammonia and urea build up. This is the answer. A long answer is given below.
Protein metabolism is one of the most complex processes carried out by living organisms because it includes the breakdown of amino acids and their conversion into other amino acids, sugars, fats, and other metabolic intermediates. The products of protein metabolism, which include nitrogenous wastes like ammonia and urea, are potentially toxic and must be removed from the body. The liver is responsible for metabolizing the nitrogenous wastes produced by protein metabolism, which are excreted by the kidneys.
If the liver or kidneys are damaged or functioning poorly, the buildup of nitrogenous wastes in the bloodstream can lead to serious health issues. Additionally, the energy required for protein metabolism is higher than that required for other types of metabolism, as proteins contain 9 kcal/gram of energy, compared to 4 kcal/gram for carbohydrates and fats. Therefore, the body must expend more energy to break down and metabolize protein. Finally, ATP cannot be made from protein, as it can from carbohydrates and fats, which are more efficient energy sources. As a result, the body must use protein to make glucose or fatty acids, which can then be used to produce ATP.

What type of growth does the population of deer exhibit on walla walla island for the first 6 years?
Answers
For the first six years, the deer population on Wallah Wallah Island increases dramatically before stabilizing.
Natural fluctuations in white-tailed deer numbers occur throughout the year. Birth rates for deer rise, as do numbers when other animals enter the region (immigration). Deer populations decline as a result of fatalities, animal emigration, or dispersal (emigration). Births plus immigration minus deaths plus emigration equals population change.
Deer populations, like those of the majority of other species, follow a predictable pattern of growth after the breeding season and drop after the hunting season and winter mortality. Over the course of a year, a population's deer numbers change.
The peak deer population is during late spring and early summer when fawns are born. The deer population is slightly decreased throughout the summer by fawn predation. In the fall, hunters kill extra animals to lower the population. Due to some deer passing away from sickness, malnutrition, and predator attacks, mid-late winter is when the population is at its lowest.
Deer populations' capacity to successfully reproduce and sustain a stable population throughout time is influenced by a variety of factors. Disease, predator-prey interactions, habitat erosion and degradation, food availability, hunting pressure, and meteorological conditions are a few of these. Deer populations are dynamic and constantly alter due to a variety of circumstances.
Deer populations are constrained from procreating at a rate that exceeds what their environment can support. Population levels may decrease if limiting forces are present in excess.
Deer require food, drink, shelter/cover, and room to move around and locate their daily needs in order to thrive. These are the crucial elements that make up a habitat. They are essential to deer's ability to survive and procreate.
Because they are herbivores, deer eat only vegetation. The majority of the water that deer require comes from the plants they consume. A deer needs shelter and cover to survive for a variety of reasons, including protecting young fawns from predators, avoiding bad weather, and evading hunters. Each deer must have access to all the food, water, and cover it requires while traveling. Its home range encompasses this region.

the correct pathway for bile is the gallbladder, pancreas, small intestine.a. trueb. false
Answers
The statemnet "the correct pathway for bile is the gallbladder, pancreas, small intestine is false because the correct pathway for bile is the liver, gallbladder, and then the small intestine.
Bile is produced in the liver and transported via the common hepatic duct to the gallbladder where it is stored and concentrated. When needed, the gallbladder releases the bile into the cystic duct, which joins the common bile duct, and finally reaches the small intestine to aid in digestion and absorption of fats. The pancreas produces and releases digestive enzymes into the small intestine, but it is not involved in the pathway of bile.
Bile helps to emulsify fat, breaking it down into smaller droplets that can be more easily digested and absorbed by the body. The pancreas also plays a role in fat digestion by producing enzymes that break down fats, proteins, and carbohydrates in the small intestine.

Would you expect isolated mitochondria to be able to carry out the oxidation of glucose with the accompanying production of ATP
Answers
Yes, isolated mitochondria are capable of carrying out the oxidation of glucose with the corresponding production of ATP.
The mitochondria are the primary site of cellular respiration and produce ATP via oxidative phosphorylation, which occurs within the inner mitochondrial membrane (IMM).
When glucose is oxidized through glycolysis, the resulting pyruvate enters the mitochondria, where it is converted to acetyl-CoA via the pyruvate dehydrogenase complex.
Acetyl-CoA then enters the citric acid cycle and is oxidized to produce NADH and FADH2, which are utilized in the electron transport chain (ETC) to generate a proton gradient across the IMM.
This proton gradient is then used to drive ATP synthesis by the ATP synthase enzyme. Therefore, isolated mitochondria are able to carry out glucose oxidation and ATP production via oxidative phosphorylation.

what system works with the respiratory system to circulate blood and oxygen throughout the body
Answers
The circulatory system works with the respiratory system to circulate blood and oxygen throughout the body.
The cardiovascular system (also called the circulatory system) transports blood from the heart to the lungs, where it is oxygenated. After receiving oxygen, blood is pumped out of the heart and into the body's arteries. Veins return blood that is low on oxygen to the heart, where the pumping process can begin again. Your body's organs, muscles, and tissues can't function properly without a strong circulatory system. The job of the circulatory system is to transport blood all over the body. The body's organs, muscles, and tissues would not function to keep you alive if the blood didn't circulate through them.
