if bread is exposed to air at room temperature, fungi inevitably colonize it. what does this say about the presence of fungal spores in our environment?

Answers

Answer 1

Answer:

This supports the fact that fungal spores exists in the atmosphere or air

Explanation:

Fungi is a kingdom of living organisms that have distinguished characteristics from plants and animals. They propagate themselves using structures called SPORES. Some of these spores are able to withstand extreme or adverse unfavorable conditions and germinate when conditions are favorable. Most fungal spores are air-borne i.e are dispersed by air.

According to the information in this question, Fungal spores will colonize bread that is exposed to air at room temperature. This implies that fungal spores are present everywhere in the atmosphere looking for opportunities to germinate. The bread is a place conducive for fungal growth due to the presence of nutrients and a favorable temperature.

Answers

Answer:

TEs are repetitive and mobile elements, thereby it is hard to trace their origins  

Explanation:

Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

If the male is a carrier then the outcomes will be XX, Xx, Xx, xx so they will have a 1:4 chance of getting white eyes if the male is NOT a carrier then it will be XX+Xx = XX, XX, Xx, Xx with no chances of having white eyes

Describe DNA synthesis in detail

Answers

Answer:

DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.

Answer:

The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.

Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.

(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.

(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.

(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

Which type of mining would NOT be used to mine coal

Answers

Answer:

Coal is mined in two different ways: from deep underground and in

strip mines. In both cases the land that is mined is leased by the coal companies, while the ownership remains in public hands. Deep mines are reached through a shaft into the ground, through which miners gain access to the coal seam and out of which comes the coal. Strip mines are used when the coal seam is near the surface. The topsoil and other overburden materials are removed by giant power shovels and piled out of the way. The shovels then dig out the coal. After the coal has been mined, there may be environmental reclamation to return the land to its original state, thus allowing others continued use of it for their own purposes. This involves refilling the hole, spreading topsoil, and then planting new vegetation on it.

The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominant, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38

Answers

Answer:

The correct answer is - 1133.

Explanation:

According to H-W equilibrium;

p2 +2pq + q2 = 1 ........... eq.1   and

(p+q)2 = 1 ..............eq.2

Here q = frequency of the recessive allele,

and p = frequency of the dominant allele in the population

The genotype of p2 + 2pq shows the dominant(taster) phenotype.

The genotype of q2 shows the recessive(non-taster) phenotype.

q^2 = (2400 - 1482)/2400

= 0.3825  

= 0.618

using eq. 2 we get p= 1-q

=0.382

2pq = No. of heterozygotes/2400

No. of heterozygotes = 1133.1648

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

Answers

I am pretty sure it is D slows to zero, don’t get mad at me if I’m wrong I’m pretty sure I am correct though.

In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.

What is Logistic growth model?

The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.

In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.

Therefore, the correct option is D.

Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.

Describe what happens to DNA during the S stage of interphase.

5. What does EGS stand for in geothermal energy?
A) Engraved Geothermal System
B) Enhanced Geothermal System
C) Exhaust Gas System
D) Engineered Geophysical System​

Answers

(EGS) stands Enhanced Geothermal Systems which can greatly increase geothermal energy utilization. Therefore, option (B) is correct.

What is EGS?

Enhanced Geothermal Systems (EGS), which are also referred to as engineered geothermal systems on occasion, present a significant opportunity for significantly broadening the application of geothermal energy.

In an EGS, fluid is injected into the subsurface under conditions that are carefully regulated. This causes previously closed cracks to reopen, which in turn creates permeability in the rock. The increased permeability of the rock makes it possible for fluid to move freely within the newly fractured rock and for heat to be transported to the surface, where it can be used to create electricity.
