Mary determined that 5 pollen grains could fit along the diameter of the field of view of her microscope. If each pollen grain has a diameter of 0.3mm what is the diameter in millimeters of the field of view of Mary's microscope
1.5mm
15mm
4.7mm
5.3mm
Answer:
1.5mm
Explanation:
According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.
This means that the diameter of the field of view of Mary's microscope can be calculated as follows:
Diameter of each pollen × no. of pollen that fit in
= 0.3mm × 5
= 1.5mm
Hence, the diameter of the field of view of Mary's microscope is 1.5mm.

Answer:
is expressed roughly equally in both sporulating and nonsporulating yeast
Explanation:
A DNA microarray (also called DNA chip) is a microchip-based testing platform which can be used to analyze and compare gene expression profiles between samples. A DNA microarray contains microscopic DNA spots attached to a solid surface, where each spot corresponds to thousands of copies of a specific DNA sequence (i.e., probes). Subsequently, cDNA 'target' molecules obtained by reverse transcription from RNA are then hybridized to a microarray. This process of hybridization can be quantified by using fluorophore-labeled targets that determine the level of the expressed gene (transcript) in the target sample. In a DNA microarray, the intensity and types of color in each spot indicate the presence and level of each specific transcribed gene in the samples. In consequence, the presence of yellow spots in the DNA microarray indicates approximately equal expression levels of the corresponding gene in both yeast samples.

In your own words explain why you think it is hard to restore ecosystems to their original conditions once they have shifted. Why doesn't re-introducing predators always 'fix' the trophic cascade? To answer this, think about some of the changes you have seen in ecosystems around the world and even in Maryland. Why can't we always restore balance?
Answer:
This is because predators will find the easiest meals to snack on, even if that includes hunting down endangered or vulnerable species they're supposed to protect.
Explanation:
An example would be the Hawaiian mongoose case. If you don't know, mongoose are very popular due to their brave and aggressive nature, where they'll hunt pests down from rats eating on crop fields to even giant snakes in India that would other wise kill humans in a single venomous bite. This brought up the idea of bringing mongoose to Hawaii, since some rats were being a problem with their agriculture. So they brought 72 of them and started breeding them.
This immediately backfired as they caused many native birds and other native animals trouble as they were eating its eggs. There were so few mongoose hunting down the rats that it was rather better for them to not bring it in the first place. This is why today, Hawaii is very strict on what animal you choose to bring, even your own dog!
Another example would be the Australian dingoes. Except, this was unintentional. A few thousand years ago, their once-domesticated dog ancestors were actually abandoned by their owners from some Southeast Asian area and came down to Australia. They outcompeted existing predators such as the Tasmanian devils on Australia. They simply could produce and maintain more offspring than the Tasmanian devils. This caused the extinction of the last Tasmanian devils in the last couple of decades.
Although the dingoes aren't as bad as the mongoose, who ate everything they could find, as they hunted feral pigs as well as rare hunts on feral cats, they also eat the threatened native species they're meant to protect.
Last and very good example would be New Zealand, home to the most vulnerable birds: Kiwis and Kakapos. Although the taxonomy shows that they have individually evolved flightlessness, they both are vulnerable species. This is because, similar to the dodos, they didn't have predators to begin with. And you can't have a predator to attack the existing invasive species since they'll just snack up on the flightless birds as they're an easier snack anyways.
The more an ecosystem has been isolated, the harder it is to restore balance once invasive species have been introduced. Predators will not hesitate to try new food, such as kiwis. Think about it, if you walk into a pastry and see a new type of cake on display, you might as well give it a go. Predators are just too unpredictable that it's best to leave an ecosystem alone.

A sperm fertilized an egg. Which two structures will the fertilized egg contact?
ovary and fallopian tubes
fallopian tubes and uterus
uterus and cervix
cervix and ovary
Answer:
B Edge 2021
Explanation:
I just took the test
When a sperm fertilizes an egg, the fertilized egg, also known as a zygote, will travel from the fallopian tube to the uterus, where it will implant and grow into a fetus. Therefore, the correct option is B.
What is a fertilized egg?A fertilized egg is also known as a zygote. It is a single cell that results from the union of a sperm and an egg during fertilization. Fertilization typically occurs in the fallopian tube of a female reproductive system when a sperm successfully penetrates and merges with the egg.
The egg is released from the ovary and travels through the fallopian tubes towards the uterus. It is in the fallopian tubes where the egg can be fertilized by a sperm, forming a zygote.
The zygote will then continue to travel through the fallopian tube towards the uterus. As it approaches the uterus, the zygote will undergo several cell divisions, forming a ball of cells known as a blastocyst.
The blastocyst will then implant into the lining of the uterus, where it will continue to grow and develop into a fetus. The cervix, which is the lower part of the uterus, plays a role in pregnancy by keeping the fetus inside the uterus during gestation and then opening to allow for delivery during childbirth.
Therefore, option B) the fallopian tubes and uterus is correct.

Cystic fibrosis is a disease. Find out a little about what it does, whether it is dominant or recessive, and whether or not gender has any bearing on the risk of inheriting the disease. Report your findings here.
Cystic fibrosis is an autosomal recessive condition caused by a mutation in the CFTR gene that alters Cl- and Na+ transport, leading to excesive mucus accumulation in aerial and digestive tracts.
What is Cystic fibrosis?Cystic fibrosis is an autosomal recessive condition in which the mutation of a diallelic CFTR gene that codes for the channel CFTR protein (cystic fibrosis transmembrane conductance regulator) is responsible for the affection.
The CFTR protein expresses in the luminal portion of the secretory and absorptive epithelial membranes, and it is involved in Cl- and Na+ transport.
Given that defects in the CFTR protein take to a defective regulation in the Na+ channel, cystic fibrosis characterizes by alterations in electrolytes secretions and absorption. There are two significant physiopathological mechanisms:
1) altered Cl- secretion in submucous glands,
2) increased Na+ absorption and consequent electrolytes hyperabsorption in the superficial epithelium.
Patients with cystic fibrosis are incapable of increasing their secretory transport. On the contrary, the increased epithelial Na+ conductance and the altered permeability to Cl- and water lead to hyperabsorption in the patient epitheliums.
The superficial liquid layer in the aerial vias decreases, mucus is not released from mucous glands, and the mucociliary clearance is strongly altered in aerial vias. Mucus accumulates in the lungs, digestive tract, and other areas.
Most people have two copies of the normal allele (h0m0zyg0us dominant genotype)and produce the functional CFTR protein form.
Patients with cystic fibrosis have two copies of the mutated allele (h0m0zyg0us recessive genotype), producing the protein's mutated and dysfunctional form.
Heter0zyg0us people possess only one normal CFTR allele and a mutated form of the same gene. These alleles are codominant, meaning that noth of them are expressed. They can produce a normal protein and a mutated protein.
Given that the normal allele produces enough functional CFTR protein, these individuals do not have any adverse effects, and the mutated allele is recessive at a physiological level.
To sum up, Cystic fibrosis is an autosomal recessive condition -not sex-linked- that causes the unfunctional form of the CFTR protein, and alters Cl- and Na+ transport. Consequently, there is an accumulation of mucus in the respiratory and digestive tract, among other organs, that might be lethal.

Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils
Answer:
basophils
Explanation:
Basophils are a class of white blood cells known as granulocyte, which also include neutrophils, eosinophils, and mast cells. These cells (basophils) are generated in the bone marrow as other white blood cells. When stimulated, basophils degranulate to release histamine, proteoglycans, and proteolytic enzymes and thus mediate immune responses. This process of degranulation occurs when a specific antigen binds to the IgE receptor on the basophil. Moreover, basophils may also be activated by inflammatory mediators (e.g., complement factors such as C5a and C3a, chemokines, etc).

Select the correct statement about equilibrium.
a) the weight of the endolymph contained within the semicircular canals agains the maculae is responsible for static equilibrium.
b) due to dynamic equilibrium, movement can be perceived if rotation of the body continues at a constant rate
c) cristae respond to angular acceleration and deceleration.
d) hair cells of both types of equilibrium hyper polarize only, resulting in an increased rate of impulse transmission.
Answer:
cc) cristae respond to angular acceleration and deceleration.
Explanation:
The vestibular system is the sensory apparatus of the inner ear that acts to maintain body equilibrium, as well as to coordinate the position of the head and eye movement. The vestibular system consists of five distinct sensory organs: three semicircular canals (i.e., anterior, posterior, and lateral) which are involved in dynamic equilibrium; and the two otoliths (i.e., utricle and saccule), involved in static equilibrium. The crista ampullary (plural: cristae) is the sensory organ located in the semicircular canals of the inner ear of vertebrates, which act to detect angular acceleration and deceleration. The cristae of the semicircular canals respond to the rotational movement and are responsible for dynamic equilibrium.

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.
Group of answer choices.
A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.
Answer:
embryo; revealed; evolutionarily.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
It's a fact that all living organisms do not reproduce the same way.
However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.
Hence, we refer to this type of study as developmental biology
