The expression of a characteristic that depends on the contribution of each of the alleles involved in the interaction is referred to as quantitative heritability. A phenotype is expressed by the interaction of many genes. 1) 140 mm / 2) 0.2344

Quantitative heritability refers to the transmission of phenotypic traits whose expression is influenced by the combinatorial action of several genes.

The expression of the characteristic is controlled by the interaction of many genes. Additionally, there may be more than two alleles in these genes.

Genotypic graduation is brought about by the interaction of numerous genes and alleles, which can result in a wide variety of combinations.

You can quantify traits like longitude, weight, and the number of eggs laid by each female.

These characters do not categorize people into distinct and distinct groups. Instead, they divide people into numerous categories based on how the genes interacted and were dispersed during meiosis.

The outcome is determined by how much each allele contributes to the genotype and phenotype at the end. Depending on their level of contribution, they interact and produce a range of phenotypes.

Fungi are important decomposers, especially in forests. Some kinds of fungi, such as mushrooms, look like plants.

Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting.

The two common examples of decomposers are bacteria and fungi. They play an important role in clearing the debris of dead remains of plants and animals and convert them into humus which enriches the nutrients of the soil.

Based on what you have read in the Gizmo, the fill up of the blanks with the words “liquid,” “gas,” or “solid” are:

Melting is the process of converting a solid into a liquid by increasing its temperature. As the temperature of a solid increases, its particles gain energy and begin to move more quickly.

Eventually, at a certain temperature known as the melting point, the particles have enough energy to overcome the forces holding them together and the solid becomes a liquid.

Note that Freezing is the opposite process of melting, it is the process of converting a liquid into a solid by decreasing its temperature. As the temperature of a liquid decreases, its particles lose energy and begin to move more slowly. Eventually, at a certain temperature known as the freezing point, the particles have lost enough energy to overcome the forces holding them apart and the liquid becomes a solid.

Answer:

16400g

Explanation:

The amount of Calcium nitrate {Ca(NO3)2} that will be needed can be calculated as follows:

Molarity (M) = number of moles (n) ÷ volume (L)

According to this question, molarity = 0.2M, volume = 500L

number of moles = molarity × volume

number of moles (n) = 0.2 × 500

n = 100moles

Using mole = mass/molar mass

Molar mass of Ca(NO3)2 = 40 + {14 + 16(3)}2

= 40 + (14 + 48)2

= 40 + 62(2)

= 40 + 124

= 164g/mol

Mass = mole × molar mass

mass = 100 × 164

mass = 16400g of Ca(NO3)2

Functions and body structure of Fungi are all fungi are heterotrophic and some fungi are filamentous or unicellular. Mycelia are hyphae used for the absorption of nutrients. Some fungi also secrete digestive enzymes. So, the correct options are (A), (C), (E) and (F).

Fungi are the kingdom of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the macroorganism mushrooms that contain chitin in their cell walls. Thus, fungi differ in form and size. Mycelia are composed of small-diameter hyphae that form an interwoven mass, providing greater surface area for nutrient absorption.

Most fungi are composed of hyphae—long filamentous structures that can fuse and connect through anastomosis and form the mycelium. They can increase their surface with structures like haustoria and arbuscules for the absorption of nutrients.

All fungi are hosts; Some species live as decomposers and others as symbionts. Fungi are like animals, heterotrophs, which means that none of them make their own food through photosynthesis like plants. Fungi can be decomposers, parasites or symbionts

Some fungi secrete digestive enzymes into the environment and then absorb the digested nutrients which is an example of heterotrophic nutrition (obtain carbon and nutrients from other organisms or other sources, but not produce their own). .

Answer:

1. Carol is heterozygous for hemophilia. Her husband does not carry the allele for hemophilia. What is the probability that they will have a daughter with hemophilia? A son with hemophilia?

Solution:

Since Carol is heterozygous for hemophilia, she has one X chromosome with the hemophilia allele and one X chromosome without the hemophilia allele. Her husband, who does not carry the allele, has one X chromosome without the allele and one Y chromosome.

The probability that they will have a daughter with hemophilia is 0, as the daughter would need to inherit the hemophilia allele from both parents, which is not possible in this case.

The probability that they will have a son with hemophilia is 50%, as the son will inherit the hemophilia allele from Carol (who passes one of her X chromosomes to her son) and the Y chromosome from his father.

2. Jake suffers from red-green colorblindness. He married Janet who is not colorblind nor a carrier. What is the probability that they will have a daughter with color blindness? A son with colorblindness?

Solution:

Jake suffers from red-green colorblindness, which means he has a recessive allele for the condition on his X chromosome. Janet is not colorblind nor a carrier, which means she has two normal X chromosomes.

The probability that they will have a daughter with color blindness is 0, as the daughter would need to inherit the recessive allele for color blindness from both parents, which is not possible in this case.

The probability that they will have a son with color blindness is 50%, as the son will inherit the recessive allele for color blindness from Jake (who passes his X chromosome to his son) and a normal copy of the X chromosome from Janet.

3. William suffers from hemophilia. He married Sandra who is a carrier of the trait. What is the probability they will have a son with the disorder?

Solution:

William has hemophilia, which means he has a recessive allele for hemophilia on his X chromosome. Sandra is a carrier of the trait, which means she has one normal X chromosome and one X chromosome with the hemophilia allele.

The probability that they will have a son with hemophilia is 50%, as the son has a 50% chance of inheriting the hemophilia allele from Sandra (who passes one of her X chromosomes to her son) and a 50% chance of inheriting the Y chromosome from William.

4. Which of the following could be the parents of a colorblind female?

a) A normal male and a normal female (not a carrier)

b) A normal male and a female carrier

c) A colorblind male and a normal female (not a carrier)

d) A colorblind male and a female carrier

Solution:

A colorblind female can only occur if she inherits the recessive allele for color blindness onboth of her X chromosomes. Therefore, the only possible parents of a colorblind female are a colorblind male and a female carrier (option d).

Option a is not possible because both parents are normal and do not carry the color blindness allele. Option b is not possible because the female carrier would need to pass on the recessive allele for color blindness to the daughter, which is not possible as the daughter would inherit a normal X chromosome from the father. Option c is not possible because a normal female cannot carry the recessive allele for color blindness.

Hope this helps!

For any recessive disease to occur it is necessary that both the recessive alleles are expressed in the individual. 1) probability of a hemophilic daughter is 0  and a son is 50%. 2) Probability of a color-blind son is 50% and a daughter is 0. Hemophilic son - 50 %. 4) Option D is correct.

1) The probability that they will have a hemophilic daughter is zero. This is because to express the hemophilic trait one allele of the trait must be inherited from both the parents, but here the mother is a carrier while the father does not carry any allele for the disease.

The probability that they will have a hemophilic son is 50%. This is because he will inherit an X chromosome from his mother who is a carrier of the disease and one Y chromosome from his father.

2) The likelihood of having a color-blind daughter is 0 because the daughter would have to inherit the color-blind recessive allele from both parents.

The likelihood of having a color-blind son is 50% because the son inherits the color-blind recessive allele from Jake (through his X chromosome) and the normal X chromosome from Janet.

3) The likelihood of having a hemophiliac son is 50% because the son inherits 50% of the hemophilia gene from Sandra (passing one of her X-chromosomes to the son) and 50% of the Y-chromosome gene from William.

4) A colorblind woman can only become a colorblind woman if she has a recessive gene for color blindness in both her X-chromosomes. So, the only parents of a female who is colorblind are male and female carriers of the recessive gene.

Answer:

Natural selection is a process where the environment changes and populations have genetic variation, leading nature to select organisms with advantageous traits for survival and reproduction.

Explanation:

Complete sentences:

The environment needs to change in order for natural selection to occur because different traits may become advantageous or disadvantageous in different environmental conditions, leading to differential survival and reproduction.

Populations have some genetic variation, meaning that individuals within a population differ in their traits, including physical, behavioral, and physiological characteristics.

Nature selects organisms with specific traits to survive and reproduce based on their ability to adapt to the environmental conditions and compete for resources, leading to the accumulation of advantageous traits over generations.

Abbott and Costello Meet Frankenstein is a classic comedy-horror movie that parodies the original Frankenstein film. There are several moments/scenes in Abbott and Costello Meet Frankenstein that fit the definition of parody.

Moment/Scene 1: In one scene, Wilbur (Lou Costello) is sitting in a chair reading a book, while a monster hand creeps up behind him. When Wilbur finally notices the hand, he slaps it down and says, "I'm reading!" This moment parodies the original Frankenstein film, where the monster's hand reaches up out of the lab table. The parody lies in the absurdity of the situation and Wilbur's nonchalant reaction.

Moment/Scene 2: Another moment that parodies Frankenstein is when the monster (Glenn Strange) runs into the lab and smashes through the door. This is a direct reference to the scene in the original film where the monster first comes to life and breaks out of its restraints. However, in Abbott and Costello Meet Frankenstein, the scene is played for laughs, with the monster's clumsiness and the exaggerated sound effects adding to the comedic effect.

Moment/Scene 3: The final moment that parodies Frankenstein is when Dracula (Bela Lugosi) tries to hypnotize Wilbur into doing his bidding. This is a nod to the original film's use of hypnosis as a plot device, but in Abbott and Costello Meet Frankenstein, the scene is played for laughs. Wilbur's resistance to the hypnotism and the absurdity of the situation add to the comedic effect.

In each of these moments/scenes, the film is imitating and exaggerating characteristics of the original Frankenstein film in an absurd and nonsensical way. This fits the definition of parody, as the film is making fun of the original work in a humorous manner.
