a. bird's-nest fungi
b. common puffballs
c. earthstar puffball
d. shelf fungi
e. corn smut

Answers

Answer:

Birds nest fungi: Basidicarp, a cup shaped with several lenticular bodies appear as bird's nest with eggs. The eggs are called the peridioles and the nest serves release the eggs onto the twigs or branches and spores are liberated .

common puffball: The young fruit body is covered with whitish spines that become mark of scar after maturity.

Earth star puff balls: The fruiting body is in the shape of an egg, it has an outer part that separates away from the inner basidiocarp and splits into several rays which curve backwards and resembles a star.

shelf fungi: The fruiting body develops on the tree trunks and termed conk which are tough and leathery often plate-like growing out of the tree trunks.  

corn smut: The diploid teliospores germinate and undergo meiosis to result in four haploid basidiospores.

An ecologist counted the number of eggs in randomly selected nests in a population of birds. To test the hypothesis that the number of eggs per nest follows a Poisson distribution at the 5% level of significance, you will need to compare a calculated value with a critical value.
Eggs Number of nests Prob Expected
nest, xi per fi
0 15 0.2845 19.9
1 29 0.3576 25.0
2 19 0.2248 15.7
23 7 0.1331 9.3
SUM: 70 1.0000 70.0
What are the calculated and critical values for this test?
a. calculated = 45.6; critical = 5.991.
b. calculated = 3.10; critical = 5.991.
c. calculated = 5.89; critical = 5.991.
d. calculated = 3.10; critical = 7.815.

Answers

Answer:

d. calculated = 3.10; critical = 7.815.

Explanation:

To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :

The test statistic is defined as :

χ² = Σ(Observed - Expected)² / Expected

Observed = number of nests

χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)

χ² = 3.1089

The critical value :

df = n - 1 = 4 - 1 = 3

The critical value ;P(χ² at 0.05, df = 3 ) = 7.815

What are amino acids?

Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. There are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.

Answers

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Anaerobic respiration of yeast produces ethanol and carbon dioxide, which can be experimentally tested by determining the rate of CO2 production in a closed system.

What is anaerobic respiration?

Anaerobic respiration is a series of chemical reactions by which certain organisms can produce energy (ATP) in absence of oxygen.

Anaerobic respiration is useful in experimental settings to determine the survival rate of yeast, which can be determined by measuring the concentration of products of this process.

The experimental procedure requires the use of a closed system to determine the rate of change between reactants (glucose) and products (ethanol + carbon dioxide).

In conclusion, Anaerobic respiration can be experimentally tested by determining the rate of CO2 production.

D. Heart attacks occur when coronary artery disease is treated.

Answers

C) Coronary artery disease can reduce blood flow to the heart and cause heart attacks

CAD (or atherosclerosis) affects the vessels that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower. And due to inadequate supply of blood, the heart muscles get damaged. This can lead to a heart attack!

In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _____ % of the first generation of offspring plants were _____.

Answers

Answer:

In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _100_ % of the first generation of offspring plants were tall pea plant_.

Explanation:

After crossing the two types of plants, Mendel observed that among the F1 there were only tall variants, while the other variant (short) disappeared. Mendel named "dominant" the expressed variant. Mendel then let these new plants auto pollinate and observed the results in the second generation, F2. He saw that the short variant that had previously disappeared, reappeared again. Both tall and short plants were present in the F2. Mendel named "recessive" the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.

Mendel concluded that each plant had a pair of factors -which he named alleles-, and that each factor coded for one trait -tall and short-. He thought that these factors -T and t- separate -segregate- during gamete formation. This conclusion is known as the segregation principle (First Mendels´ Low).

At which location is contact metamorphism least likely to occur

1. divergent boundary
2. convergent boundary
3 .transform boundary

Answers

I say it’s transform boundary

Contact metamorphism is the result of rising of hot magma, where by contact, other previously solidified rocks also metamorphize. This events occurs in convergent and divergent plate boundaries.

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

Contact metamorphism refers to a localized metamorphism. It occurs in the vicinity of intrusive igneous rocks and results from the term effects of hot magma.

Contact metamorphism occurs under elevated temperatures and low-pressure conditions. It is closely related to magmatism.

It occurs in oceanic dorsals, where the extremely hot magma rising to the surface metamorphizes other previously solidified magmatic rocks.

It is very common to find this metamorphism at both convergent and divergent plate boundaries, where molten rock is produced.

I. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. Also, collisions create volcanic arches and continental arches. In these boundaries, blueschists form by contact and regional metamorphisms.

II. Divergent: New crust is created by the rising molten materials coming from the mantle when two plates separate. A stream of hot material creates a new seabed between the separating plates, producing the sea bottom expansion. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. Chlorite and plagioclase metamorphic rocks are formed by contact metamorphism.
