Answers

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

Answer:

The average kinetic energy of the gas particles is greater in container B because its particles move faster.

Answers

The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna

For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed

QUESTION 1

According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.

According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:

3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)

2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:

A. 2:1
B. 1:1
C. 1:3
D. 3:1

Answers

Answer:

D. 3:1

Explanation:

Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.

However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

15. Assuming the fluorescence threshold is set to be 1. Which gene has the highest gene expression rate? What is the Ct value? Gene with highest expression = ______________ Ct value = _______________

Answers

Answer:

The correct answer is - Gene 1 and 14.5 (or 14).

Explanation:

The cycle threshold is denoted as Ct value. It is the cross point at the threshold line meets with fluorescence signal reaction curve. In the given RTpcr experiment, the threshold line is fluorescence intensity 1 thus, Ct value for each gene will be the point at which each curve meets the fluorescence intensity line at 1. Ct value of is inversely proportional to amount of nucleic acid in the given sample.

Here, the Ct for gene 1 is the lowest, so the amount of DNA would be highest.

Gene with highest expression= Gene 1

Ct value= 14.5

As you read in this chapter, fungi have long formed symbiotic associations with plants and with algae. How may these two types of associations lead to emergent properties in biological communities

Answers

Answer:

Fungi show symbiotic association with algae and plants. With plants, they thrive as endophytes in a form of the symbiotic association. This symbiotic association results in the emergence of novel characteristics in the world of biology.  

The lichens function as a tool in finding the quality of air, as they grow in the environment containing good air quality. The tolerance towards heat is another characteristic. Some of the endophytes are witnessed in the plants, which grow in very hot conditions.  

At such conditions, no fungi or plant can thrive, however, in the symbiotic association, they possess the tendency to thrive. If one tries to separate them, it results in the death of both.

Answers

Answer:

This question lacks options, options are:

A) glial cell

B) interneuron

C) sensory neuron

D) motor neuron.  

The correct answer is D.

Explanation:

The brain sends instructions to the muscles that control voluntary movement through nerve cells called motor neurons. The function of the motor neuron is basically to carry the information that comes from the descending pathways of the spinal cord, in order to generate an activation in the tissues of the skeletal and visceral muscles of all parts of the body. Motor neurons need the information sent to them by sensory or efferent neurons. Since in order to perform the appropriate muscle movements for the situation, our brain must receive information from the outside. By sending sensory stimulation through interoreceptors, motor neurons can regulate visceral activity, stimulating or inhibiting the activity of their effector tissues. In this way, our nervous system integrates the information from both types of neurons and allows us to move and react according to the demands and circumstances of our external context.

What is a major role that fungi play in ecosystems

Answers

Answer:

Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.

The data table and the cladogram below provide information about the evolutionary history of several different species of animal. Using this information, which of the following is true of trout?

They are more closely related to salamanders than they are to birds.

They are more evolved than salamanders and lizards.
They evolved into a separate species due to the presence of lungs.
They have jaws and lungs but lack claws or nails, feathers, and mammary glands.

Answers

Answer:

They are more closely related to salamanders than they are to birds.

Explanation:

According to the data, trout are more closely related to salamanders than birds.

The first data table shows how the salamander only has one extra trait that the trout does not have (lungs).

On the other hand, birds have three extra traits that the trout doesn't have (claws/nails, feathers, and lungs).

The cladogram further shows how trout are more closely related to salamanders compared to birds.

Trout and the salamander are closer together on the cladogram, while the bird is further away. This means they are more related on the evolutionary timeline.

So, the correct answer is that They are more closely related to salamanders than they are to birds.

The statement which is true about Trout is as follows:

They are more closely related to salamanders than they are to birds.

Thus, the correct option is A.

What is Cladogram?

A Cladogram may be defined as a type of family tree or classification tree which is based on evolutionary relationships. It is also known as a phylogenetic tree.

Trout and the salamander are positioned closer to one another on the cladogram while the bird is being far away. The presence of lungs is marked from the salamander, so trout do not have lungs.

Trouts evolved from Hagfish but not from salamanders and lizards. Trouts only have jaws but lungs, claws or nails, feathers, and mammary glands.

Therefore, the correct option for this question is A.
