In Mendelian cross, codominance and incomplete dominance the heterozygous will always have a unique phenotype. As they don't differ in this matter, B is incorrect.

There is a heterozygous phenotype and it is different than a homozygous recessive or a homozygous dominant, and it applies to Mendelian cross, to codominance and to incomplete dominance as well. Therefore, C and D are also incorrect.

The Mendelian laws of inheritance does not identify codominance or incomplete dominance, but it can lead to their identification as they do not differ in its function. Therefore, the correct answer is A. There is no difference.

Answer:D

Explanation:

Photosynthesis main energy source is solar energy while cellular respiration uses chemical energy

The main source of energy in the process of photosynthesis in plants is radiant (solar) energy. Plants convert this solar energy into chemical energy in the form of sugars (food). Thus, the correct option is D.

Photosynthesis is the phenomena by which plants prepare their food. Photosynthesis takes place in the chloroplast of green leaves. The chloroplast contains chlorophyll. Chlorophyll is the pigment responsible for photosynthesis. Chlorophyll traps the solar energy (light) in the cells which is then converted into chemical energy. The chemical energy is in the form of sugars (glucose).

In cellular respiration, the chemical energy in the form of glucose is converted into ATP (energy currency of the cell).

Therefore, the correct option is D.

Answer: soil

Explanation: Soil

According to 2 sources

Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N 2) to ammonia (NH 3), thereby breaking the tough triple bond of molecular nitrogen.

Answer:

Scientific Theory

Explanation:

The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.

In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.

Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

Answer:

a. protects the environment.

Explanation:

Using water efficiently means using it wisely and not wasting it. When we use water more efficiently, we reduce the amount of water we consume, which helps to conserve water resources. This is important because water is a limited resource, and by using it efficiently, we can ensure enough water is available for future generations.

By using water more efficiently, we can also protect the environment. Water is essential for many ecosystems and habitats, and by conserving water, we can help maintain the balance of these ecosystems. Additionally, using water efficiently can reduce the need for energy-intensive water treatment and distribution processes, which can help reduce greenhouse gas emissions and mitigate climate change.

So, using water more efficiently helps protect the environment but also helps conserve water resources for the future.

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.

By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.

In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.

The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.

The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

If matings are not random in a population and individuals mate with other individuals of similar genotype/phenotype, h0m0zyg0us frequencies increase. In this example, the genotype frequency for Mm is F(Mm) = 0.25.

---------------------------------

In the exposed example, one of the assumptions of Hardy-Weinberg equilibrium is not accomplished. There are non random matings.

Individuals mate with other snails of the same genotypes

MM  x  MM

Mm  x  Mm

mm  x  mm

We can assume this is an example of matings by similar phenotypes.

Eventually, this mating system leads to an increase in the h0m0zyg0us genotype frequency, at the expense of heter0zyg0us ones in loci that determine the trait.

Allelic frequencies do not change. Only genotypic frequencies do.

This mating system tends to separate the population into two subgroups, decreasing the amount of heter0zyg0us individuals.

          Matings              Progeny                              

Zygotic population of the next generation

So, in the exposed example we know that the frequency of the dominant allele M is 0.5

f(M) = p = 0.5

knowing that p + q = 1, we can clear the equation to get the frequency of the recessive allele.

p + q = 1

0.5 + q = 1

q = 1 - 0.5

q = 0.5

f(m) = q = 0.5

Zygotic population of the next generation

       F(MM) = p² + 1/4 (2pq)

       F (MM) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125

       F(MM) = 0.375

        F(Mm) = 1/2 (2pq)

        F(Mm) = 1/2 (0.5)

        F (Mm) = 0.25

        F(mm) = q² + 1/4 (2pq)

        F(mm) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125

        F(mm) = 0.375

The expected genotype frequency for Mm individuals in this population is F(Mm) = 0.25.

Estimated budget: $4.4 million

Studio(s) that distributed the movie: United Artists

Actors:

P. McMurphy - Jack Nicholson

Nurse Ratched - Louise Fletcher

Martini - Sydney Lassick

Cheswick - Sydney Lassick

Tabor - Christopher Lloyd

Chief Bromden - Will Sampson

Billy Bibbit - Brad Dourif

Turkle - Scatman Crothers

Synopsis:

One Flew Over the Cuckoo’s Nest is a drama film that follows the story of Randle McMurphy (Jack Nicholson), a criminal who pretends to be insane to avoid hard labor in prison. He is sent to a mental institution where he meets Nurse Ratched (Louise Fletcher), the head nurse who has a strict and authoritarian approach to mental health treatment. McMurphy’s arrival shakes up the ward, and he becomes a leader and a role model for the other patients, including Martini (Sydney Lassick), Cheswick (Sydney Lassick), Harding (William Redfield), Tabor (Christopher Lloyd), Chief Bromden (Will Sampson), and Billy Bibbit (Brad Dourif). McMurphy challenges Nurse Ratched’s authority, and their power struggle leads to a tragic ending.

Examples of how the film has shown mental health treatment:

1. In one scene, Nurse Ratched conducts a group therapy session where she asks the patients to share their feelings. When Billy Bibbit admits that he is afraid of women, Nurse Ratched humiliates him by forcing him to stand up and reveal his sexual insecurities in front of the group. This scene shows the insensitivity and lack of empathy that some mental health professionals display towards their patients.

2. In another scene, McMurphy organizes a fishing trip for the patients, and they all escape the hospital for a day. During the trip, they bond with each other and experience a sense of freedom and joy that they cannot find in the hospital. This scene highlights the importance of socialization and leisure activities in mental health treatment, and how they can have a positive impact on patients’ well-being.

3. In the climax of the film, McMurphy undergoes a lobotomy, a surgical procedure that was once a common treatment for mental illness. The scene is graphic and disturbing, and it shows the brutality and inhumanity of some mental health treatments that were used in the past.

What the film is trying to say about mental health treatment during this time period:

One Flew Over the Cuckoo’s Nest is a critique of the mental health system in the 1960s, which was characterized by institutionalization, medication, and control. The film shows how mental health professionals often treated their patients as objects rather than human beings, and how they used their power to maintain order and conformity at the expense of patients’ dignity and autonomy. The film suggests that mental health treatment should be more humane, individualized, and empowering, and that patients should be treated with respect and compassion.

Final summarizing statement and personal rating:

One Flew Over the Cuckoo’s Nest is a powerful and thought-provoking film that raises important questions about mental health treatment and human rights. The film is well-acted, well-directed, and has a memorable soundtrack that enhances the emotional impact of the story. I highly recommend this film to anyone who is interested in mental health, social justice, and human psychology. I give this film a rating of 4.5 out of 5 stars.

The graph shows that the condition that is best for enzyme activity is A. A temperature of about 25 ° C

This is because the graph shows that the rate of enzyme activity increases as the temperature increases from 0°C to 25°C. However, the rate of enzyme activity decreases as the temperature increases above 25°C. This is because the enzyme denatures at high temperatures, which means that it loses its shape and function.

Differences between central nervous system and peripheral nervous system:

The central nervous system is made up of the brain and spinal cord.

The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

Simply, it is the separation of the nervous system into it’s two main parts. Each of these parts can be broken down into more specific parts.

Brain and body are connected, they communicate. Most of the sensors take information from your body to the brain. For the brain to act, commands from the brain are transmitted to the body. If there were no peripheral nerves, you will have no information from the skin, muscles, pain receptors, etcetera transmitted to the brain.

Components of nervous system:

The peripheral nervous system can be divided into two components:

-the somatic nervous system: controls voluntary actions such as walking.

-the autonomic nervous system: is responsible for the control of vital functions such as heart beat and breathing. This one has also two parts:

--> Parasympathetic division (rest and digest)

--> Sympathetic division (active and alert)

The phenomenon where a non-native species invades an ecosystem and outcompetes the native species causing the native species to decline potentially to extinction is called "invasive species.

It occurs when non-native species, also known as invasive species, establish themselves and thrive in an ecosystem, causing harm to the native species. Invasive species possess traits that give them a competitive advantage over the native species, such as rapid reproduction, efficient resource utilization, and resistance to local predators or diseases.

The consequences of biological invasions can be severe. The invasive species can outcompete native species for resources like food, habitat, and water, leading to a decline in native populations.

They may also directly predate upon or introduce diseases to native species, further exacerbating their decline. In some cases, the native species are pushed to the brink of extinction or even driven to extinction.

Biological invasions are a significant global concern due to their ecological, economic, and social impacts. They can disrupt ecosystem functioning, alter natural habitats, reduce biodiversity, and cause economic losses in industries like agriculture, forestry, and fisheries.

Efforts are made to prevent and control invasive species through monitoring, early detection, and management strategies such as eradication, containment, and control programs to mitigate their negative effects and protect native species and ecosystems.

Answer:

Amino acids are the monomers that makeup proteins. This amino acid is unionized, but if it were placed in water at pH 7, its amino group would pick up another hydrogen and a positive charge, and the hydroxyl in its carboxyl group would lose and hydrogen and gain a negative charge.

Explanation:

Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. In the aqueous environment of the cell, both the amino group and the carboxyl group are ionized under physiological conditions, and so have the structures -NH3+ and -COO–, respectively. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. This R group, or side chain, gives each amino acid protein-specific characteristics, including size, polarity, and pH.
