A researcher with a reputation for yelling at graduate students wants to know how the seed yield of transgenic plants (that are constructed specifically with the objective of increasing seed yield) she is growing in a plot compares to that of the wild-type plants growing in another plot. The entire population of the wild-type plants have been characterized, but she only has enough funding to measure a sample of the transgenics. Her null hypothesis is that the average seed yield of the transgenics will not differ from the wild-type. Her graduate student secretly has an arm injury, and hasn't told her for fear of inciting the researcher's reputed wrath. Because his arm hurts, the graduate student inadvertently collects less heavy samples. This type of non-random sampling would increase the likelihood of committing a Type II error.
a. True
b. False
Answer:
False, it is a Type I error.
Explanation:
A Type II error is produced by not reject the null hypothesis when the alternative hypothesis is true, thereby the null hypothesis is false, but is erroneously not rejected. On the other hand, the Type I error may be caused by random variation in the data or errors in the research techniques to be used when the sample is obtained.
In this case, it is a Type I error caused when the sample was obtained (i.e., due to the graduate worker collected less heavy samples).

When ______ is released, the subsequent receiving neuron ________ fire because that neurotransmitter is _______.
Answer:
When a neurotransmitter is released, the posterior receptor neuron has the receptor to bind to it because that neurotransmitter is a stimulator of the postsynaptic membrane.
Explanation:
The neurotransmitters that are released from the motor plate, that is, from the postsynaptic membrane to the presynaptic space, are captured by receptors of the postsynaptic membrane, which can be another neuronal structure to transmit an impulse or a muscle to be able to execute the contraction.
I leave you an image that draws up the stimulation of the postsynaptic membrane by means of a neutrotranismor, these are called as: adrenaline, norepinephrine, acetylcholine, etc.
Number 1 is the presynaptic membrane that releases the neurotransmitter (yellow balls), number 2 is the intersynaptic space, 3 is the postsynaptic membrane that in number 4 can be seen to be activated by relating to the neurotransmitter

A researcher examined the response of dandelions to herbivory by rabbits. She finds that in a greenhouse with no rabbits, there is variation in the number of seeds produced by different dandelion plants. She then mimics herbivory by rabbits and finds that dandelions that have been "eaten" by rabbits produce more seeds. From this she concludes:___________
a. The number of seeds of a dandelion is a genetically variable trait
b. Dandelion seed number is a constitutive defensive response to rabbit herbivory
c. Rabbits cause a decline in the number of dandelion seeds
d. Rabbits alter the genetics of dandelions as they feed on them
Answer:
b.
Explanation:
Based on the information provided within the question it can be said that from this info the researcher can conclude that Dandelion seed number is a constitutive defensive response to rabbit herbivory. This is mainly due to the fact that Dandelions that have been eaten by the rabbits have produced more seeds, meaning that the Dandelions defense mechanism produces more seeds when attacked in order to prevent the flower's extinction.
name two major vessels that return oxygen-poor blood to the heart. What are the damages for each? Where do they terminate?
Answer:
1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.
2. Lower limb - inferior vena cava - bottom of the right atrium.
Explanation:
The Heart pumps the oxygen-rich blood to the different parts of the body to Otake oxygen and nutrients to these organs and then takes the oxygen-poor blood returns from the body to the heart.
The two major vessels that return oxygen-poor blood to the heart are 1. superior vena cava (SVC) that drainages Head, neck, upper limb, thorax and terminate at top of the right atrium, and 2. inferior vena cava (IVC), Lower limb and terminate at bottom of the right atrium.
1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.
2. Lower limb - inferior vena cava - bottom of the right atrium.

A pea plant has one recessive allele for white flowers and one dominant allele for purple flowers. What flower color will the pea plant have
Answer:
the phenotype is PURPLE
Explanation:
The pea plant will have purple color due to the presence of a dominant allele.
What is the law of dominance?In a heterozygote, one trait will mask the existence of some other trait for the same feature, according to Mendel's rule of dominance. The dominant allele will be expressed only, rather than both alleles contributing to a phenotype. The recessive gene will continue to be "latent," but it will be passed on to progeny in the same way that the dominant allele is.
Only kids with two copies of this gene will exhibit the recessive phenotype; these offspring will reproduce true when self-crossed. Dominant and recessive relate, by definition, to the genotypic interactions of alleles that result in the phenotype of the heterozygote.
The fundamental idea is genetic: which of the two alleles in a heterozygote gets expressed, resulting in an individual that has the same phenotype as one of the two homozygotes. The term "dominant trait" or "dominant allele" is occasionally used to refer to the characteristic associated with the dominant allele and "recessive trait" to the trait associated with the concealed allele. However, this could make it difficult to comprehend the idea of phenotype.
Therefore, the pea plant will have purple flowers due to the presence of a dominant allele.

Streptomyces griseus produces the antibiotic Streptomycin, which inhibits protein synthesis by binding to ribosomes and preventing the binding of fMet‐tRNA. Why isn’t S. griseus harmed by its own antibiotic?
Answer:
See the answer below.
Explanation:
Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.
Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.
In the case of Streptomyces griseus, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.

Answer:
Explanation:
1. Prereplication complex forms at one of many origins of replication.
2. The initiation complex creates an active replication fork as helicase unwinds DNA.
3. RNA primers are added to provide a 3 end for elongation.
4. DNA polymerase synthesizes both the leading and lagging strands from 5' to 3'.
5. RNA is replaced with DNA and lagging strands are joined.
6. Active telomerase can extend the lost telomere region.
All these process are the steps involved in the replication of DNA. The replication of DNA involves the biological production of two identical copies of DNA from one original DNA molecule. This is a very important biological process of life as it is involved in the inheritance pattern of life. It is essential in that the 2 daughter cells formed must contain the same sets of chromosome as the original parent.
state and explain five uses of insects
Answer:
They help our eco system
Explanation:
PROVIDERS
Insects are in nearly every food chain. Many larger animals—birds, bats, amphibians, and fish—eat insects before they in turn are eaten by predators. The dearth of insects is suspected to be a leading cause of recent declines in bird populations.
DECOMPOSERS
Waste-eating insects unlock nutrients for use by the ecosystem that would otherwise stagnate in dung, dead plants, and carrion. Dung beetles process parasite- breeding and grass-killing cattle dung in 23 months versus the 28 it would otherwise take.
PEST CONTROLLERS
By feeding on crop-threatening pests, predatory insects perform the role of pesticides without chemicals. This cuts pest-control costs and increases yields, saving agricultural industries billions of dollars every year—while reducing toxic pesticide residue on crops.
POLLINATORS
Nearly 90 percent of flowering plant species and 75 percent of crop plant species depend on pollination by animals—mostly insects. Overall, one out of every three bites of food humans eat relies on animal pollination in the production process.
SOIL ENGINEERS
Termites (and ants) can trans- form soil in hot, dry climates. Their tunneling aerates hard ground, helping it retain water and adding nutrients. In some regions, the introduction of termites has turned infertile land into cropland within a year.
Answer:
Pollination, Food, Silk, Dyes, Dermestids for cleaning skeletons.
Explanation:
Pollination. Honeybees are among the most important of pollinators, and their efforts result in about 80% of all pollination in the United States.
Food. Honey is made by insects and can be consumed by humans.
Silk. Most silk is produced from the cocoons of the Silkworm.
Dyes. Many insects provide dyes that are used in cosmetics and for coloring cakes, medicines and beverages.
Dermestids for cleaning skeletons. Carpet beetles feed on almost anything organic and have been used in museums by technicians to clean the skeletons of mammals.
A is an agent that causes disease. All are pathogens.
