inhibition is a mechanism of succession in which Group of answer choices the arrival of one species at a site affects the subsequent colonization of other species. one species decreases the probability that a second species will become established. one species increases the probability that a second species will become established. the probability that a species can become established depends on the presence of another species.
Answers
Answer:
option B: one species decreases the probability that a second species will become established
Explanation:
Inhibition as a mechanism of succession occurs when some early species which could also include pioneer species make the site less suitable for the development of other species and do not allow them to become established and grow. When eventually these early species die, other species that were hindered will subsequently grow and become established gradually giving rise to a climax community.

The presence of a mutualist spider in a certain area improves the survival of an herbaceous shrub by reducing the impact of herbivorous insects. These spiders are preyed on by lizards, and lizards are eaten by birds. An increase in the density of lizards would most likely have a _______ direct effect on spiders and a _______ effect on the plant.
Answers
Answer:
An increase in the density of lizards would most likely have a negative direct effect on spiders and a negative indirect effect on the plant.
Explanation:
Many animals modify their environments, apparently to reduce predation risk .Scincid lizards are included or excluded from 21 replicated plots, and spiders therein are classified as exposed or sheltered, depending on whether they are uncovered in their web or hidden in cocoons, leaves/debris, or burrows. Exposed spiders are greatly affected by the presence of predatory scincid lizards, whereas sheltered spiders are not. More specifically, lizards, which forage close to the ground, reduce the abundance of exposed spiders by two-thirds but have no effect on the abundance of sheltered spiders. Sheltered spiders are able to avoid predation and share space with lizards, suggesting that shelter construction is a mechanism for reducing predation risk and has important population consequences.

For the following types of mutation, what would be the affect if any on cell proliferation?
(a) a mutation that prevents dimerization of the receptor
(b) a mutation that destroys the kinase activity of the receptor
(c) a mutation that inactivates the protein tyrosine phosphatase that normally removes the phosphates from tyrosines on the activated receptor
(d) a mutation that prevents the binding of the normal extracellular signal to the receptor
Answers
Answer:
Option C, a mutation that inactivates the protein tyrosine phosphatase that normally removes the phosphates from tyrosines on the activated receptor
Explanation:
Protein tyrosine phosphatases (PTP) causes dephosphorylation of protein due to which the pathways for signal transmission get terminated, growth of cell also get inhibited along with cell proliferation, and differentiation. Cell proliferation is a mechanism by which the number of cells increases in an organism. Also this mechanism keeps a balance between the cell divisions and cell loss.
Since this growth factor Superchick is stimulating the proliferation of cultured chicken cells by inhibiting the functioning of Protein tyrosine phosphatases due to which cell growth is not terminated and more cultured mutated cells are originating
Hence, option C is correct

Most of the Blackland Prairie ecoregion of Texas has been converted to farmland and ranches. Between crop harvests, some farmers grow a type of plant called a cover crop, while other farmers leave the fields bare. How do these practices affect the soil of the Blackland Prairie?
A. Planting a cover crop or leaving the ground bare are both practices that will completely prevent soil erosion.
B. Equal amounts of erosion by wind and runoff will occur on farms, regardless of whether cover crops are planted.
C. More erosion by wind and runoff will occur on farms with cover crops than on farms without cover crops.
D. Less erosion by wind and runoff will occur on farms with cover crops than on farms without cover crops.
Answers
Answer:
D. Less erosion by wind and runoff will occur on farms with cover crops than on farms without cover crops.
Explanation:
A cover crop is a crop planted to protect the soil from erosion, diseases, etc rather than to produce crop yield.
This type of crop has prevention of soil erosion on the farmland among one of its many functions. Other functions include increasing soil quality, suppress weeds, etc.
Cover crops prevent erosion by reducing the amount of water that is drained off a land because of its deep roots which enables water to be sieved from the ground. Their residue is left on the land to prevent excess water runoff, thereby protecting the land from erosion during heavy rainfall.
Some examples of cover crops are legumes and grasses.
Therefore, farmers in Blackland Prairie that leave their farms bare are more at risk of erosion than farmers that plant cover crops.

11. look at problem 11. what if the mRNA has a frameshift mutation and lost the 3rd C in the second codon, whoa would the new mRNA strand be?
Answers
The new mRNA formed is AUG CCC UAU AUG GUA GAG UGU AG
Explanation:
Frameshift mutation is a condition when either a nucleotide is added or deleted and the code is no longer triplet codon. This change causes the shifting of the frame of DNA sequence and the coding of amino acid is affected because mRNA is transcribed according to the mutated DNA sequence.The different amino acid than expected is the outcome.
In the given mRNA strand:
mRNA : AUG CCC CUA UAU GGU AGA GUG UAG
the condition given is if frame shift mutation takes place in 3rd nucleotide in second codon, the third C is lost, the resulting mRNA is:
new mRNA formed is AUG CCC UAU AUG GUA GAG UGU AG
The sequence of amino acid will change and also there will be a loss of amino acid in the polypeptide as only 2 nucleotides in the triplet codon is there.

Answer:
mutation
Explanation:
I'm not sure, but it can be.
Any change in the normal nucleotide sequence that codes for an amino acid is called a - mutation.
Amino acids are composed of two functional groups the amnio group, and the carboxyl group. They join together to make a polypeptide chain resulting in the formation of a protein.
In a living cell, DNA is composed of four bases adenine (A), thymine(T), guanine (G), and cytosine (C), while in RNA, the T is replaced by uracil (U).DNA is transcribed to mRNA, and three bases in mRNA together form a codon.One amino acid is formed from one codon - for instance bases A, U, G form a codon AUG and encode methionine (amino acid).Therefore, if any change occurs in the normal base sequence of the DNA is considered as mutation (Point mutation)The mutation will be carried to its mRNA, leading to defective amnio acids.Sickle cell hemoglobin is one such exampleThus, any change in the normal nucleotide sequence that codes for an amino acid is called a - mutation.

Describe the role of Cyanobacteria in charging Earth's early atmosphere
Answers
Cyanobacteria, through photosynthesis, played a crucial role in transforming Earth's early anoxic atmosphere by producing oxygen. This led to the Great Oxygenation Event, which allowed for the evolution of aerobic organisms and ultimately paved the way for the diversity of life that we see today.
Explanation:Role of Cyanobacteria in Earth's Early AtmosphereThe role of cyanobacteria, often referred to as blue-green algae, was instrumental in transforming Earth's anoxic early atmosphere. These organisms are known for their ability to perform photosynthesis, a process that results in the production of oxygen. Initially, Earth's atmosphere had no molecular oxygen, and anaerobic organisms were the only forms of life able to survive. Cyanobacteria evolved from early phototrophs, and their emergence around 2.5 billion years ago sparked a significant change known as the Great Oxygenation Event.
Through their photosynthetic activities, cyanobacteria began releasing substantial amounts of oxygen into the atmosphere. This not only changed the atmospheric composition but also led to the first-known mass extinction, as many anaerobic organisms could not withstand the presence of oxygen. However, this event also paved the way for the evolution of aerobic life forms, including multicellular organisms, and the development of more efficient oxygen-utilizing catabolic pathways. The oxygenation also contributed to the formation of the ozone layer, which protects living organisms from harmful ultraviolet radiation.
Furthermore, the rise of cyanobacteria and the subsequent oxygenation of the atmosphere is thought to have been a driving force behind the evolution and increased colonization of land by more complex life forms. Hence, cyanobacteria played a crucial role in shaping Earth's atmosphere and the direction of evolutionary history on the planet.
The presence of more than two alternative forms of a given gene would be called ________. a.alternation of generations b.incomplete dominance c.hemizygosity d.codominance e.multiple alleles

The presence of more than two alternative forms of a given gene is called multiple alleles. This is seen in the ABO blood group system in humans, which also exemplifies codominance.
Explanation:The presence of more than two alternative forms of a given gene is referred to as multiple alleles. This term generally applies in genetics where, although an individual can have only two alleles for a specific gene (one from each parent), there may exist more than two alleles within a population. A common example of this is the ABO blood group system in humans.
The ABO blood group system exhibits both codominance and multiple alleles. In this system, there are three alleles: IA, IB, and i. Both IA and IB are dominant to i. However, neither one is dominant or recessive to the other. IA and IB are codominant. Hence, a person with an IAIB genotype will have type AB blood.

How does the loss of bicarbonate due to diarrhea increase the protons in the blood?
Answers
Answer:
Increase of protons (H+) in the blood causes acidosis. These effects decrease hemoglobin’s affinity for oxygen and weakens its capacity to bind and increasing the haemoglobin dissociation.
Loss of bicarbonate stores by diarrhoea or tubular renal waste results in a state of metabolic acidosis leads increased concentration of plasma chloride and decreased concentration of plasma bicarbonate. Decrease in plasma bicarbonate leads to increase in H+ ions causing acidosis.
When a substance moves across the plasma membrane along a concentration gradient at a rate faster than would be expected by simple diffusion alone but without the expenditure of metabolic energy, the process is best described as:
A. Facilitated diffusion
B. active transport
C. pinocytosis
D. the work of an ion pump
E. Osmosis
Answers
Answer:
A. Facilitated diffusionExplanation:
The plasma membrane is an important membrane that is present in the cell and plays an important role in the exchange of the materials across the cell. This membrane is made up of phospholipid bilayers and some other components. Movement of the substances across the membrane takes place by two methods such as an active process in which the energy required and the other is the passive process in which energy is not required.Diffusion, osmosis, and facilitated diffusion are an example of passive diffusion. Facilitated diffusion is such type of passive movement in which the membrane proteins helps in the transport of the substances across the membrane and thus the is faster than other passive processes. In this process no energy is required and movements take place along the concentration gradient.
Molecules are moved over the membrane using one of two methods: an active process that requires energy, or a passive mechanism that does not.
The process is best described as a form of passive diffusion (Facilitated diffusion) option A.
Facilitated diffusion is a sort of passive movement in which specific transmembrane integral proteins aid in the transport of molecules across the membrane.This result in a faster process than other passive processes.There is no need for energy in this particular transport process and movements are made along the concentration gradient.
