Answer: (c) They include no human components.

Explanation: An ecosystem is a biological community made of living organisms (biotic factors like humans, animals, and plants) and their environment (abiotic factors such as rocks, the sun, and water).

The law of segregation states that the genes are separated from each other during gamete formation and are recombined during fertilization.

Law of segregation was the second law of inheritance and presented by Mendel. It explained that the genes existed in a pair of alleles and during gamete formation, only one of the two alleles was received by a single gamete.

Fertilization is the process of the fusion of the male and the female gametes. It results in the formation of zygote that is diploid in nature as both the gametes are haploid. The process of fertilization may occur inside the female body or on the external environment.

Which of the following best describes what will result when a glucose-fed yeast cell is placed in an anaerobic environment? The yeast cell will produce ATP through fermentation, generating CO2​ and ethanol as byproducts.

75 is the % yield if 4 moles of hydrogen is reacted with 3 moles of oxygen and produces 3 moles of water. chemically water is known as H2O.

A water patch is made up of two hydrogen tittles and one oxygen snippet. But you can not just stick two hydrogen tittles together and call it a day. The factual process of producing water is a little more complicated 2H2O Energy = 2H2 O2. Two motes of diatomic hydrogen( H2) must be combined with one patch of diatomic oxygen( O2) to produce two motes of water( H2O)( O2). During the process, energy will be released. This response( 2H2 O2 = 2H2O Energy) has been known for over two centuries, but no one has succeeded in making it work in a homogeneous result until now.

An animal will choose to eat the prey that offers the greatest energy yield per unit of effort.

The easiest way to understand conduct from an evolutionary standpoint is as a feature that can fulfill the three requirements for evolution through natural selection.

When an organism's own survival and ability to reproduce is put at risk, kin selection is the evolutionary strategy that favors the success of its relatives' procreation. Kin selection can make kin altruism appear to be selfless behavior that has evolved over time.

Overall, the case for reciprocal altruism in species other than humans is tenuous. Nonhuman animals appear to be far more "in the present" than humans, and the majority, if not all, of help-giving behavior can be explained by kin selection or by immediate rewards.

This is possible due to genetic predisposition which means that there is an increased chance that a person will develop a disease based on their genetic makeup.

The most commonly mutated gene in people with cancer is p53 or TP53. More than 50% of cancers involve a missing or damaged p53 gene. Most p53 gene mutations are acquired.

Germline p53 mutations are rare, but patients who carry them are at a higher risk of developing many different types of cancer. When the functions of these genes are mutated in order to express different proteins, the disease or cancer is exposed in the individuals.

Therefore, the influence of genetic mutation with respect to disease is possible due to genetic predisposition which means that there is an increased chance that a person will develop a disease based on their genetic makeup.

Morgan examined the data and hypothesised that a process of crossing over, or recombination, could account for his findings. He specifically suggested that information could "cross over" between the two paired chromosomes.

A component that can be discovered in the nucleus of a cell. On a chromosome, proteins and DNA are organised into genes.  Chromosomes are the DNA units that transmit inherited traits from one generation to the following. Because they transmit hereditary traits to the DNA of the following generation, they are referred to as the seat of hereditary information.

Hermann Henking in Leipzig was the first to recognise the X chromosome's unique characteristics in 1890. Henking discovered that one chromosome did not participate in meiosis while researching the testicles of Pyrrhocoris. The reason why chromosomes have this moniker is because they may absorb stains (chroma in Greek means color). The basic units of information for DNA are nucleotide base pairs, and chromosome 1 covers around 249 million of them.

If the members of one homologous pair did not segregate to opposite poles, but instead, both went to the same pole, then it would lead to trisomy.

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibers in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.

DNA may be precisely duplicated during these cell divisions because of chromosomes.  

If the members of one homologous pair did not segregate to opposite poles, but instead, both went to the same pole, then it would lead to trisomy. Hence, two chromosomes lack chromosomes, while two chromosomes will have two copies of chromosomes.

When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body's tissues.

Aorta is the largest artery that carries blood and oxygen from the heart throughout the body. The structure of the aorta begins at the aortic valve which separates the aorta from the left ventricle of the heart. The left ventricle is the last chamber through which blood flows towards the heart.

Just above the aortic valve, there are two branches known as the left main coronary and the right main coronary. These two branches of the aorta are responsible for transporting blood to the heart muscle. From the aortic valve, the aorta moves upward, extending around the second rib.

This section is known as the ascending aorta. Then, the aorta curves down and to the left. This part is called the aortic arch. From here, the aorta runs down the body to a final section called the descending aorta.

Aorta is very important for the human body because it is the main blood vessel that supplies oxygenated blood to all tissues and organs of the body to keep them functioning properly.

So, if there is a problem with the aorta, such as a blockage, structural anomaly, or rupture, it can harm other organs of the body. Problems with the aorta can be triggered by uncontrolled high blood pressure and cholesterol.

Thus, several ways can be done to maintain the health and function of the aorta, such as consuming a balanced nutritional diet, doing physical activity, stopping smoking, and regularly seeing a doctor to monitor your blood pressure and cholesterol.

Dr. Natterson-Horowitz is a cardiologist at UCLA and a contractor who helped the Los Angeles Zoo, she realized that the divide between treatment of humans and animals in contemporary society.She explains that one of the reasons for this divide is that medical doctors and veterinarians have traditionally been trained in separate disciplines, with little overlap or communication between the two.

One of the three conditions Dr. Natterson-Horowitz mentions that have been well-studied by veterinarians, is cancer, veterinarians have been studying cancer in animals for decades and have developed treatments and therapies that are now being applied to human patients.

Dr. Natterson-Horowitz's argument is that physicians can learn a lot from veterinarians. One of the strongest points in her argument is that veterinarians have been studying diseases and conditions for decades in animals, and their findings can be applied to human medicine.

One argument against the claim that medical doctors and veterinarians do not need to collaborate is that the anatomy and physiology of animals are different from that of humans, and what works for animals may not work for humans. Another argument is that medical doctors and veterinarians have different priorities and goals, with medical doctors focusing on human health and veterinarians focusing on animal health.

Therefore, Another way that these two fields could collaborate is by creating a program that allows medical students to spend time in the field with veterinarians, and vice versa, to gain a better understanding of each other's work and the similarities and differences between human and animal medicine.

Alleles occur in pairs, while genes do not. Option C.

In genetics, genes are the basic unit of heredity and represent the instructional materials for the synthesis of proteins. In other words, genes are made up of a sequence of DNAs that dictate the kind of trait to be expressed in individuals.

Alleles, on the other hand, are the complementary DNA sequence of genes. Since genes are made up of DNAs and DNAs are double-stranded, it means that each gene is made up of two complementary strands. Each strand is what is known as an allele.

For example, assuming a gene is represented by R. The gene could be RR if it is homozygous dominant, Rr if it is heterozygous, or rr if it is homozygous recessive. The two alleles make the gene while each pair are known as an allele.
