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.
Answers
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.

All of the following are evidence for the big bang except: A. Cosmic background radiation B. Almost all galaxies are red-shifted C. The sound from the bang echoes though the universe D. The universe is expanding
Answers
Answer: C. The sound from the bang echoes though the universe
Explanation:
Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.
Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.
There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.

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
Answers
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.
To control the population of insects, if insecticides are used then how it will affect the population of birds?
Answers
Answer: Birds are exposed to insecticides through ingestion by mistaking, they ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.
Explanation:
Insects are a class of invertebrate animals characterized by having one pair of antennae, three pairs of legs and two pairs of wings (which, however, may be reduced or missing). They comprise the most diverse group of animals on Earth with an estimated thirty million undescribed species, potentially representing more than 90% of the life forms on the planet. Moreover, they can be found in almost every environment on the planet, so they are not only highly diverse, but also incredibly abundant.
Like any species on the planet, insects play a vital role in the ecosystem, so that a change in the population can compromise the survival of everything around them. On the other hand, insects called "pests" are those insects observed in systems and whose populations cause damage to crops. Although both beneficial insects and pest insects are part of any ecosystem and are also present in human-managed systems. Humans combat these pests using insecticides, which are chemical compounds used to kill insects. They are usually very specific since the product only affects the organism it damages, leaving the rest of living beings and the environment unharmed. And they have low toxicity to humans and animals.
The most common way in which birds are exposed to insecticides is through ingestion by mistaking, for example, a pesticide granule for a seed, or indirectly, by consuming contaminated prey (insects). Birds may also ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. It should be noted that it also depends on the toxicity of the chemicals, the magnitude and duration of exposure. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.

Answers
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.

What is solubility?Solubility is the property of a substance to dissolve in a solvent to form a homogeneous solution at a particular temperature and pressure.The volume of water should be the same in all three groups. This is because the experiment is testing the effect of temperature on the solubility of sugar in water, and any variation in the volume of water could affect the results.
By keeping the volume of water constant, John can ensure that any changes in the amount of sugar dissolved are solely due to changes in temperature and not changes in the amount of water. Therefore, he can compare the results of each group and draw conclusions about the effect of temperature on the solubility of sugar.

Carry out a tri-hybrid cross between XX(tall) YY(fat) ZZ(fair) and xx(short) yy(slim) zz(black). Find their genotypic and phenotypic ratios.
Answers
Answer:
Genotypic ratio = 100% XxYyZz
Phenotypic ratio = 100% tall, fat, fair.
Explanation:
For a trihybrid cross involving the genes XX which codes for tallness, YY which codes for fatness, and ZZ which codes for fairness with their alternate forms being xx, yy, and zz respectively; each gene will segregate into their respective alleles and combine to form gametes during meiosis, such that:
XXYYZZ ----> XYZ, XYZ, XYZ, XYZ, XYZ, XYZ, XYZ, XYZ
xxyyzz -----> xyz, xyz, xyz, xyz, xyz, xyz, xyz, xyz
These gametes then combine randomly during fertilization to give all XxYyZz offspring.
XYZ x xyz
XxYyZz
Since X is dominant over x, Y is dominant over y, and Z is dominant over z, then XxYyZz individuals that are produced from the cross would be tall, fat, and fair. Hence
Genotypic ratio = 100% XxYyZz
Phenotypic ratio = 100% tall, fat, fair.

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
Answers
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.

Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils
Answers
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).
