(Q005) Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Describe how this process has played out in the maintenance of the sickle-cell trait. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today?
Answer:
sickle cell disease or sickle cell disease is about the inheritance of metaplastic cells or cells that do not respect normal cell morphology from the mother or father to a child.
This is not associated with cultures, instead lactose tolerance is.
Explanation:
Lactose tolerance is basically an adaptation of the body in those humans who continue to drink milk throughout their lives, once the growth stage is over, milk should be suspended, although some continue to consume it and lactase continues to be encoded and expressed.
Some people for cultural reasons or environmentalist lifestyles do not drink animal milk, but rather vegetable milk.
Compare and contrast evaporation and condensation.
Answer:
By definition, evaporation is a process where water changes into vapour. Condensation is the opposite process where water vapour is converted to tiny droplets of water. Evaporation occurs before a liquid reaches its boiling point. Condensation is a phase change regardless of the temperature.
Two different groups of scientists studying a rare trait in ground squirrels report very different heritabilities. What factors influencing heritability values make it possible for both conclusions to be correct?
Answer:
It is a trait highly influenced by environmental factors (i.e., it has low heritability)
Explanation:
In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.

What macromolecule is made from carbon dioxide?
Answer:
Plants and algae convert carbon dioxide to organic matter through the process of photosynthesis, the energy of light. Carbon is present in all life: All living things contain carbon in some form, and carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates.
All life has some form of carbon, and this element is the main building block of macromolecules like proteins, lipids, nucleic acids, and carbohydrates.
What is macromolecule?The general formula for carbohydrates is Cn (H2O)n, and they are biological macromolecules consisting of carbon, hydrogen, and oxygen. Saccharides are the precursors to all carbs. These big molecules generate energy that powers the body's physiological processes.
They are made up of thousands of atoms that are covalently bound. The polymerization of numerous smaller molecules known as monomers produces large molecules. Large non-polymeric molecules like lipids and biopolymers like nucleic acids, proteins, and carbohydrates are the most prevalent macromolecules in biochemistry.
Therefore, through the process of photosynthesis, which uses light energy, plants and algae transform carbon dioxide into organic matter.

list five different system interactions for the topic of acid rain
Answer:
1. Effects of Acid Rain on Fish and Wildlife
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
2. Effects of Acid Rain on Plants and Trees
Dead or dying trees are a common sight in areas affected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.
3. Buffering Capacity
Many forests, streams, and lakes that experience acid rain don’t suffer effects because the soil in those areas can buffer the acid rain by neutralizing the acidity in the rainwater flowing through it. The soil becomes thin because of this and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.
4. Episodic Acidification
Melting snow and heavy rain downpours can result in what is known as episodic acidification. This can result in short-term stress on the ecosystem where a variety of organisms or species may be injured or killed.
5. Nitrogen Pollution
It’s not just the acidity of acid rain that can cause problems. Acid rain also contains nitrogen, and this can have an impact on some ecosystems. For example, nitrogen pollution in our coastal waters is partially responsible for declining fish and shellfish populations in some areas. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere.
Explanation:
Not sure if this is what the question was asking for.
Acid rain is defined as rain or any other kind of precipitation that is particularly acidic, including high quantities of hydrogen ions. Acid rain has a pH lower than drinking water, ranging from 4-5 on average.
What are the different system interactions for acid rain ?1. Acid Rain's Impact on Fish and Wildlife
Acid rain's biological consequences are most visible in aquatic areas such as streams, lakes, and marshes, where it can affect fish and other species. Acidic rain water can drain aluminum from soil clay particles as it passes through the soil and into streams and lakes.
2. Acid Rain's Effects on Plants and Trees
In acid rain-affected locations, dead or dying trees are prevalent. Aluminum is leached from the soil by acid rain. Aluminum may be damaging to both plants and animals. Acid rain also depletes the soil of minerals and nutrients required by trees to develop.
3. Capacity for Buffering
Many woods, streams, and lakes that experience acid rain remain unaffected because the soil in such locations can buffer the acidity in the precipitation flowing through it. As a result, the soil becomes thin and unable to effectively neutralize the acid in the rain water. As a result, these locations are more sensitive, and the acid and aluminum can build up in the soil, streams, and lakes.
4. Acidification on Occasional Basis
Melting snow and strong rain can cause a condition known as episodic acidification. This can cause short-term stress in the environment, injuring or killing a range of creatures or species.
5. Nitrogen Pollution
Not only may the acidity of acid rain cause difficulties. Acid rain includes nitrogen, which can have an influence on some ecosystems. Nitrogen contamination in our coastal waterways, for example, is partly to blame for dwindling fish and shellfish populations in some locations. Aside from agriculture and sewerage, much of the nitrogen created by human activities that reaches coastal waterways originates in the atmosphere.

9. True or False? A human cell will have 46 chromosomes during metaphase of meiosis II.
Answer:
True
Explanation:
Similarly, in humans (2n=46), there are 46 chromosomes present during metaphase, but 92 chromatids. It is only when sister chromatids separate – a step signaling that anaphase has begun – that each chromatid is considered a separate, individual chromosome.
The statement that the human cell will have 46 chromosomes during the metaphase of meiosis II is false.
Chromosomes refer to the thread-like structures that can be found in the nucleus of organisms. The chromosome consists of protein as well as a single molecule of DNA.
It should be noted that the human cell has 23 chromosomes during the metaphase of meiosis II. It doesn't have 46 chromosomes during the metaphase of meiosis II.
Therefore, the statement is false.

1. What is the total amount of carbon removed from the atmosphere each year by the ocean and land plants?
2. What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?
3. How much will atmospheric carbon change in one year?
*From the Carbon Cycle Gizmo
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
The carbon cycle.
Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
Explanation:
From the Carbon cycle the answers to your questions are ;
1) The Total amount of carbon removed from the atmosphere each year is
65 GTC2) The Total amount of carbon added from soil and burning of fossil fuels is
69 GTC3) The Change in atmospheric Carbon in a year = 4 GTC
The amount of Carbon present in the atmosphere within a given period is determined by the amount of carbon added to the atmosphere and the amount of carbon that leaves the atmosphere within a given period.
1) Total amount of carbon removed from the atmosphere = amount of carbon removed by oceans + amount of carbon removed by plants
= 2 GTC + 63 GTC = 65 GTC
2) Total amount of carbon added to the atmosphere from soil and burning fossil fuels = 9 GTC + 60 GTC = 69 GTC
3) The change in atmospheric carbon in a year
= amount of carbon added - amount of carbon removed
= 69 GTC - 65 GTC = 4 GTC.
Hence we can conclude that the amount of carbon added = 69 GTC, amount of carbon removed = 65 GTC and the change in atmospheric carbon is 4 GTC.

Answer:
resource partitioning
Explanation:
Resource partitioning can be defined as the division of limited resources that enables species to avoid competition when they live in the same habitat. Moreover, interspecific competition is defined as the competition for limited resources among individuals of different species. In a given environment, species can be competing for essentially the same limiting resources. In the case of the bumblebees, the competence is reflected by differences based on the length of the proboscis (competence for the food), thereby resource partitioning enables species to coexist with one another.

The first step in glycogen synthesis is the phosphorylation of glucose.
Answer:
The correct answer is True
Explanation:
The first step in glycogen synthesis (glycogenesis) is the phosphorylation of glucose to form glucose-6-phosphate, which is catalyzed by hexokinase. [This step is also the first step in the glycolytic pathway]. Glucose-6-phosphate is then isomerized to glucose-1-phosphate by the action of phosphoglucomutase. This glucose-i-phosphate is then converted to glycogen by glycogen synthase.
Given what you learned about how influenza changes over time, how could you explain the emergence of drug resistance in bacterial pathogens?
Answer:
Beneficial mutations events can generate resistance to drugs
Explanation:
Bacteria can develop antibiotic resistance through mutations, as well as horizontal transference events, that allow them to reduce/eliminate the effectiveness of drugs used to treat infections. For example, penicillin-resistant strains have been identified in Staphylococcus aureus and Streptococcus pneumoniae. In general, mutations have a negative impact on the fitness of the organism; however, there are cases where mutations increase the fitness of the individual. In consequence, antibiotic resistance may occur by natural selection, where antibiotic-resistant bacteria that exhibit beneficial mutations are selected to survive and perpetuate their genetic material.
