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.

The lipid bilayer membrane of a neuron is impermeable to charged molecules or ions. To enter or exit the neuron, ions must pass through special proteins called ion channels that span the membrane. Ion channels have different configurations: open, closed, and inactive. Some ion channels need to be activated in order to open and allow ions to pass into or out of the cell. Which ion channels are used in the production of electrical signals (Action Potential) in neurons

Answers

Answer:

The correct answer is: in neurons, the most used ion channels in the production of action potentials are the channels that allow fo passage of sodium and potassium.

Explanation:

Neurons must be able to transmit and receive signals in order for the nervous system to operate. Because each neuron has a charged cellular membrane (a voltage differential between the interior and the exterior), the charge of this membrane can vary in response to neurotransmitter molecules generated by other neurons as well as external stimuli. The membrane potential is the difference in total charge between the interior and outside of the cell. This membrane potential exists thanks to the state of ion channels that may or may not allow the passage of certain ions.

A substance called a neurotransmitter allows a neuron to accept input from other neurons. The neuron will transmit the signal to downstream neurons if the input is powerful enough. The opening and shutting of voltage-gated ion channels, which produce a transient reversal of the resting membrane potential to form an action potential, are used to transmit a signal within a neuron (in one direction only, from dendrite to axon terminal). The polarity of an action potential changes across the membrane as it travels down the axon. The signal then activates other neurons once it reaches the axon terminal.

The target neuron is depolarized to its threshold potential (-55 mV) by a stimulation from a sensory cell or another neuron, and Na+ channels in the axon hillock open, initiating an action potential. The neuron totally depolarizes to a membrane potential of around +40 mV after the sodium channels open. As Na+ channels open, the action potential moves along the neuron.

The cell's membrane voltage is "reset" to the resting potential after depolarization is complete. The Na+ channels shut, signaling the start of the refractory phase in the neuron. Voltage-gated K+ channels open at the same moment, allowing K+ to escape the cell. The membrane potential returns to a negative state as K+ ions exit the cell. The cell becomes hyperpolarized when K+ diffuses out of it, resulting in a membrane potential that is lower than the cell's usual resting potential. The sodium channels revert to their resting state at this moment, ready to open again if the membrane potential rises over the threshold potential again.

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.

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.

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.

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).

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.

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.
