An enzyme called tyroinae produced the dark compound in kin (melanin). I’m albinim, thi enzyme doe not work or i not preent. Explain how each mutation could be reponible for Albinim
Answers
The majority of TYR mutations render tyrosinase inactive, preventing melanocytes from ever generating melanin. Type 1A oculocutaneous albinism is a result of several mutations (OCA1A).
The term "albinism" typically refers to oculocutaneous albinism, a group of genetic illnesses wherein the body produces little to no melanin. Your skin, hair, and eye colors are all influenced by the type and quantity of melanin in your body. Because melanin is involved in the growth and operation of the eyes as well, albinos have vision issues.
Albinism symptoms are typically visible in a person's skin, hair, and eye color, however sometimes there are minute variations. Due to their sensitivity to the sun's effects, people with albinism are more likely to get skin cancer.
Albinism has no known treatment, but those who have the condition can take precautions to protect their skin.

Graph 5- Survivorship Curves Using your textbook or an online resource, determine the differences between K-selected species and r-selected species. Next, use the graph below to answer question 24.
Answers
The difference between K-selected species and R-Selected species is that the former posses a type I survivorship curve while the latter has type III survivorship curve.
A Type III survival curve is more likely to be present in K-selected species. Type I survivorship curves are typical in r-selected species. Graphs called survival curves provide a visual representation of the proportion of a population that is still alive at various ages. R-Selected species have evolved to survive in unstable and unpredictable surroundings. They produce a great number of tiny young.
The offspring of r-selected animals are comparatively self-sufficient at birth and do not get a lot of resources or parental care. Examples of r-selected species include plants like the dandelion and marine creatures like jellyfish.
Species chosen by K are adapted to predictable, steady surroundings. K-selected species tend to have populations that are roughly at their carrying capacity. These species have long generation times, and larger but fewer offspring overall. An example of a K-selected species would be an elephant or a human.

Question 22 of 22 Several members of the family in the pedigree who suffered from a disease are colored in black. Currently deceased members of the family are struck out with a line. Based on the data in the pedigree, propose a Mendelian model that would explain the inheritance of this disease. Explain how the data is consistent with your model. A scientist hypothesizes that a mutation at a single locus is responsible for the pattern of inheritance seen in this pedigree. Explain how a mutation in a gene can arise during meiosis. Describe one strategy organisms use to prevent such mutations from arising.
Answers
A. Many families have Alzheimer's disease. From this we conclude that the disease is X-linked recessive.
B. Meiosis is the process of generating gamete cells. There are two choices: mutual break join and another non-reciprocal break copy.
Many families are affected by Alzheimer's disease. It cannot be autosomal inherited because it affects more men than women. Affected males in the second generation have many affected children with normal wives.
If it was autosomal dominant, the sick father would have passed it on to all his second-generation children, but that is not the case. Therefore, it cannot be autosomal dominant.
If it had been autosomal recessive, he would not have affected his children, as his wife appears normal. increase. Therefore, it is not an autosomal abnormality.
Not X-linked dominant, in which case the affected father passed his only X chromosome to his daughter, making her daughter sick. But in this case, the sons are involved. Therefore, it is not X-linked dominant.
From this we conclude that the disease is X-linked recessive.
B. Meiosis is the process of generating gamete cells. Mutations can occur during meiosis in various ways such as double-strand breaks, inversions and point mutations. Important mutation types include missense, nonsense, and point mutations. Cells use multiple repair mechanisms to repair DNA damage or mutations during meiosis. One of the most efficient mechanisms is double-strand break repair by homologous recombination (HR).
Here, the DNA is unwound at the mutated region by recA loading. Recombination with homologous pairs continues through the RecBCD complex.
Here are his two alternatives: reciprocal break join and another non-reciprocal break copy.
Repair normally occurs during her S phase of the cell cycle, when the cell divides its DNA. However, mutations that occur during meiosis, such as chromatid pairing and recombination, are not easily repaired. Cells stop dividing only when the mutation gets worse.

cell?
Answers
The proteins expressed and the genes activated makes one cell a brain cell and another skin cell.
Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes. However, in non-protein-coding genes like transfer RNA (tRNA) and small nuclear RNA (snRNA), the end result is a functional non-coding RNA instead of a protein.
Gene expression alterations lead to cell differentiation. This happens when various environmental signaling molecules activate or repress certain transcription factors that are required to express particular genes in the DNA. Inside of cells, DNA is arranged into chromosomes. Chromosomes have several genes.

True or False: An action potential in one section of the membrane can cause the initiation of an action potential in adjacent sections of the membrane.
Answers
True , This is the concept of axonal action potential propagation! Positive charges accumulate on subsequent regions of the membrane as a result of depolarization caused by an initiated action potential on one segment of the axon.
This local depolarization can cause an action potential to move along the axon by causing depolarization along the neighboring segment of the membrane.
Voltage-gated sodium channels open and close in milliseconds. As the cell membrane depolarizes, sodium channels open, allowing sodium ions to enter and further depolarize the membrane. This inward current causes the action potential to rise.

What is the function of the interdigital membranes in frogs? Do all frogs posses them? Explain.
Answers
Answer:
Function: To improve the animals´ movement and displacement on water.Not all frogs have well-developed membranes. Those with terrestrial habits exhibit reduced interdigital tissue.Explanation:
The interdigital membrane is the skin between the fingers and toes of the animals. This tissue is resistant and flexible. Its expansion varies among species and depends on their habits. The principal function of these membranes is to improve the animals´ movement and displacement on water. This tissue represents a broader area that provides resistance to water so the animal can swim faster and longer. On the ground, these membranes also can be useful while jumping, but this is not its principal function. The development of the interdigital membrane show variation among amphibians. In those taxa that spend most of their time in the water, the membranes are extensive and well-developed.

How do you find the effort force of a second class lever?
Answers
In a class two lever the force of the effort multiplied by the distance of the effort from the fulcrum is opposite and equal to the force of the resistance multiplied by the distance of the resistance from the fulcrum.
The force utilized to move an object across a distance is called an effort force. To use a rudimentary machine to perform work on an item, this force must be overcome. By dividing the load by the number of ropes, we may get the pulley's effort force. F is the effort force in the diagram.
For instance, when using a shovel, you hold one end stable to serve as the fulcrum and pull up on a load of soil with your other hand. The resistance force is the dirt being picked up, and the effort force is the second hand.

Which adaptations allow thermophiles, a type of bacteria, to live within the hot springs of Yellowstone National Park
Answers
The ability to live in a highly acidic environment and the ability to withstand very hot temperatures are the adaptations that allow thermophiles, a type of bacteria, to live within the hot springs of Yellowstone National Park.
what is Adaptation?
Adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment.
The main feature of Yellowstone National Park is the presence of very hot and acidic water. Starting as rain on the surface, water from hot springs seeps through the bedrock beneath Yellowstone and is superheated by Yellowstone's magma system.
Thermophilic proteins have several adaptations that give them the ability to maintain structure and function at extreme temperatures. Thermophiles, for example, have specialized enzymes that use additional hydrogen bonds, salt bridges, and disulfide bonds to resist denaturation at very high temperatures, strengthening proteins to resist unfolding increase.
