This Pedigree represents a family with an Autosomal Recessive Disorder. What is the probability that IV4 and IV5 have a child with the trait?
As this family has an Autosomal Recessive Disorder, we must know that this disorder will only be expressed, in the family members who are homozygous recessive (aa), in this way, to know the probability of IV-4 and IV-5 to present the disorder, we must evaluate the probabilities of combinations of their parents' alleles in a diagram called a punnett square.
In the pedigree above, we can see that the dark colored balls and squares represent the members of the family who have the disorder and therefore have the "aa" genotype.
Thus, when observing the crossings throughout the family, we know that the father of IV-4, has the genotype "Aa", however we do not know which genotype of the mother of IV-4, but as she does not have the disorder, she may have the genotype "Aa", or "AA", for that reason, we must make the punnett square for both situations and see what the probabilities of IV-4 will present the disorder.
As you can see in the figure attached below, if IV-4's mother has the "Aa" genotype, IV-4 will have a 25% chance of presenting the disorder. If IV-4's mother has the "AA" genotype, IV-4 has a 0% chance of inheriting the disorder.
In the case of IV-5, we can see that his mother has the disorder and therefore has the genotype "aa", we know that his father does not have the disorder, but we do not know if the father's genotype is "AA" or "Aa "and therefore we must evaluate both situations.
As you can see in the figure below called "IV-5", if IV-5's father has the "AA" genotype, IV-5 will have a 0% chance of inheriting the disorder. However, if IV-5's father has the "aa" genotype, IV-5 will have a 50% chance of inheriting the disorder.

In the presence of oxygen, what is the first stage of cellular respiration
Answer:
Glycolysis
Explanation:
Glycolysis is the first step in both aerobic and anaerobic respiration.
In the presence of oxygen, oxidative phosphorylation is the first stage of cellular respiration.
What is cellular respiration?Cellular respiration may be characterized as a type of chemical process through which oxygen is utilized in order to derive energy from carbohydrates (sugars). This chemical process involves the breakdown of food in the cell with the release of energy.
The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue and perform oxidative phosphorylation.
Therefore, In the presence of oxygen, oxidative phosphorylation is the first stage of cellular respiration.

So far, we have primarily discussed human adaptations independently of one another. In real life, of course, each person has numerous coexisting ancestral adaptations. Ignore what you know of your family history and consider only your physical traits for the following adaptations: skin color, lactose tolerance, and body shape. Based on these three traits, in what part of the world might your ancestors have originated? Do all three of your traits suggest similar ancestry? Be sure to explain your hypothesized determination using evidence related to all three traits, and be sure to think about all the forces of evolution that might impact your unique history (such as gene flow and founder effect).
Answer:
about skin coloration:
Regarding these modifications, we can say that it influences not only the knowledge of evolution but also on the development of strategies for the management of many diseases, so we know that these changes are not produced by a single agent and factors such as Melanin, a substance produced by melanocytes and which gives the tint to each tone, also includes influences such as exposure to sunlight, both in frequency and geographical area from which it is made. Keratin is also found as its own dermal factor. According to this, there has been an adaptation of the phenotype of each individual mainly to the UV environmental factor that can make changes and modify skin tone.
About lactose tolerance:
It is known that historically, after childhood for many people it was very difficult to continue consuming milk, because the enzyme lactase was not found in them and lactose digestion became very difficult, nowadays it is believed that the weather has influenced to improve digestion
About the body shape:
The inherited factors are very important, from the different habitats of our ancestors, which for reasons of hunting, solar exposure, type of food, were being inherited, today it is known that there are 3 main forms of body types including the endomorph, ectomorph and mesomorph, the main advantages depending on where the individual lives will adapt to persist in the next generation, as well as to use new ways of obtaining food can modify it

What explains why populations fluctuate around the carrying capacity?
Answer:
In population ecology: Population fluctuation As stated above, populations rarely grow smoothly up to the carrying capacity and then remain there. Instead, fluctuations in population numbers, abundance, or density from one time step to the next are the norm.
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained in that specific environment, given the food, habitat, water, and other resources available. In population ecology, carrying capacity is defined as the environment's maximal load, which is different from the concept of population equilibrium, which may be far below an environment's carrying capacity. The effect of carrying capacity on population dynamics may be modelled with a logistic function.
The populations fluctuate around its carrying capacity because it is very common even for a stable population to briefly exceed or dip below its carrying capacity.
The size of the population fluctuate due to some environmental factors, presence of predators, competitors etc.
Also reproductive lag time can also cause the population to exceed the carrying capacity temporarily.
What is carrying capacity?The carrying capacity of an environment is the maximum population size of organisms that can be supported by the ecosystem, given the food, mates, shelters and other resources available.
What is reproductive lag time?Reproductive lag time is the time required for birth rate to decline and the death rate to increase in response to resource limits.

Examination of the amino acid composition of a newly isolated protein indicates the presence of 10 lysines, 5 arginines, and 3 methionines. When the protein is treated with cyanogen bromide, four peptides are obtained. When it is treated with trypsin, 15 peptides are obtained. What do these results suggest regarding the sequence of the protein?
Answer:
It means that the cyanogen bromide hydrolyzes methionine residues with high efficiency, while trypsin is an enzyme that cuts proteins at lysine and arginine peptidic bonds, thereby producing 4 and 15 polypeptides, respectively.
Explanation:
Cyanogen bromide is a pseudohalogen compound that is used to cut the C-terminus of the methionine residues. On the other hand, the trypsin is an enzyme produced by the pancreas as trypsinogen that is used by the digestive system (intestine) to digest polypeptides.

Our genetic material, DNA, is formed from a 4 letter "alphabet" of bases: A, T, G, C (adenine, thymine, guanine, and cytosine). The order in which the letters are arranged is important, but because a molecule can move, there is no difference between a sequence and the same sequence reversed. For example, the sequence (A, A, T, A, G, A, T) is the same as the sequence (T, A, G, A, T, A, A). (In reality, DNA molecules have identifiable ends, but ignore that in this problem.) How many distinct DNA sequences of 6 bases are there
Answer:
2048
Explanation:
Since DNA is formed from a 4 letter of bases: A, T, G, C (adenine, thymine, guanine, and cytosine) therefore we have 4^5
Since the base sequence is the same as the reverse,
The number of DNA of sequence of 6 bases=4^6= 4096
Since, the reverse is the same as the forward sequence then the answer is divided by 2 =4096/2 = 2048

Plants and other producers make their food using photosynthesis
True
False
Answer:
True
Explanation:
Producers are unique set of organisms that begins a food chain or web. They are not dependent on any other organism for energy source (autotrophs). This is because of their ability to capture light energy from sunlight and use it to power the process of making their own food called PHOTOSYNTHESIS.
Photosynthesis is a unique feature of all autotrophic organisms like plants, planktons etc. It involves the use of an inorganic source (CO2) to synthesize organic food in the presence of sunlight. Plants and other producers obtain energy directly from the sun, hence, they are called PRODUCERS because they start a food chain in an ecosystem. Other organisms called CONSUMERS rely on them for energy.

What releases glucose into the blood stream?
Answer:
Insulin helps your body turn blood sugar (glucose) into energy. It also helps your body store it in your muscles, fat cells, and liver to use later, when your body needs it. After you eat, your blood sugar (glucose) rises. This rise in glucose triggers your pancreas to release insulin into the bloodstream.
