Page No Date Sex in bacteria is deteaimined by ?
Answer:
Pili
Explanation:
The sex of bacteria is determined by a structure called Pilli. Pilli is not present in all species of bacteria, but within species that have this structure, such as Escherichia coli, pilli is considered an appendage present in male bacteria.
Pilli presents itself as a long hair and can also be called F factor or fertility factor and has a reproductive function, as it allows the conjunction between two bacteria (one with pili and the other without), where the male bacteria transmit genetic resources to within the body of the female bacteria , which will combine these resources with its own resources and will give rise to another bacteria.

Refer to Animation: Cell Signaling: Adrenaline Signaling in the Heart Muscle. Adrenaline stimulates an increase in heart rate by binding to: G proteins on the cytosolic face of the plasma membrane. adenylyl cyclase. regulatory regions in genes that code for muscle cell proteins. G protein-coupled receptors on the surface of heart muscle cells. nuclear transport proteins that allow adrenaline to be taken into the nucleus to act as a transcription factor.
Answer:
The correct answer is ''G-protein coupled receptors on the surface of cardiac muscle cells.''
Explanation:
Adrenaline is a catecholamine whose pharmacological effects occur at alpha and beta adrenergic receptors. The mechanism of action of all beta adrenergic receptors is the activation of a G protein that activates adenylyl cyclase and increases cyclic AMP production. Adrenaline by b-adrenergic stimulus increases the contractile force of the myocardium (positive inotropic action) and increases the frequency in which the myocardium contracts (positive chronotropic action), consequently there is an increase in cardiac work, with a greater demand for oxygen due to the myocardium to be able to contract. Therefore, the blood flow to the heart is indirectly increased, bringing with it a greater supply of oxygen.

Explain how the adaptive changes in coat-color genes allowed mice to travel under the radar of hungry predators.
Answer:
This:
Explanation:
These adaptive changes help in ways best seen between desert mice and those who live in darker habitats. While desert mice often developed extremely light colored coats to blend best with the environment, mice who live in forest's or valleys often have darker coats to blend with foliage and trees. These coats that help camouflage with the environment protect mice in the open from being snatched by say a eagle or bird of prey. And mice who blend equally with foliage are protected more from ground predators like other small foxes or rodents
How can scientists use the fossil record to find evidence of relationships between different species?
Answer:
Species can be classified using the fossil record based on analogous or homologous structures.
Explanation:
By comparing the anatomy of both modern and extinct species, paleontologists can infer the lineage of those species, scientists use the fossil record.
What is Fossil?A fossil is defined as the preserved remains, imprint or trace of a once living thing from a past geological age. Some examples of fossils are bones, shells, exoskeletons, stone marks of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.
Fossils form the morphological, or anatomical record, through comparing the anatomy of both modern and extinct species with the comparative anatomy of present-day organisms, paleontologists can infer the lineage of those species.
Thus, by comparing the anatomy of both modern and extinct species, paleontologists can infer the lineage of those species, scientists use the fossil record.

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Name at least three neuromitters and state the roles of these neuronmitters in human body ? Except acetylcholine, (GABA)and domanine. Please help as soon .
Answer:
Explanation:
The chemical messengers present in the body are known as neurotransmitters. These are the chemicals that the nervous system uses to send and receive information between neurons and muscles. A neurotransmitter can have one of three effects on a neuron:
Excitatory effect, Inhibitory effect, and/or Modulatory effect.
The list of neurotransmitters and their roles are as follows:
Glutamate: This is present in amino acid compounds which are located in the synapses. It functions as an excitatory neurotransmitter, causing neurons to discharge instructions when stimulated in the central nervous system.
Adrenaline: It helps to respond to body's psychological stress and protection mechanism. They are positioned above the kidney and are created by the adrenal glands. They operate throughout the central nervous system and swiftly increase your heart rate and provide oxygen to your muscles.
Serotonin: Serotonin is a crucial brain neurotransmitter that also has a role in the small intestine. In your digestive tract, serotonin increases feelings of contentment after eating and controls your appetite. When you eat anything that doesn't agree with your stomach, serotonin assists your body in getting rid of it.

A. Ethanol and carbon dioxide
B. Lactate and oxygen
C. Glucose and water
D. Carbon dioxide and oxygen
(40 points!!!) (will mark brainliest if its right)
Answer:
ethanol and carbon dioxide :)
Explanation:
The correct option is A. Ethanol and carbon dioxide are the waste products of alcoholic fermentation.
What is alcoholic fermentation?A biological process called alcoholic fermentation, often known as ethanol fermentation, turns sugar into alcohol and carbon dioxide. Alcoholic fermentation is an anaerobic process since yeasts carry out this function and oxygen is not required.
The fermentation process produces heat, carbon dioxide, water, and alcohol as byproducts. In this instance, our attention is on the latter.

Why is price discrimination not positive under perfect market conditions
Answer:
[u9gbvolgj;t9ug7yh
Explanation:
ft7odt8ugde86rfgef
Price discrimination is impossible in a market with perfect competition, and the average total cost (ATC) curve is identical to the marginal cost curve (MC).
What is price discrimination?Price discrimination is a sales strategy in which the seller charges different prices for the same item or service oriented on what the seller believes the customer will agree to.
In sheer price discrimination, the seller charges each customer the highest possible price.
Price discrimination occurs when various prices are charged to different customers.
This is not feasible in a perfectly competitive market because there are numerous firms competing for the price; however, it is possible in a monopoly because people have no other place to buy.
In a monopoly, price discrimination is the practice of charging different prices for a product.
Monopolies typically have greater control over providers than regular sellers, allowing them to significantly influence the selling prices of the suppliers.
Thus, due to this, price discrimination is not positive even under perfect market conditions .

How do mountains play a role in precipitation patterns?
a. As water vapor condenses,the air gets warmer b.it changes the amount of rain received c.it changes the direction of the wind d.as vapor condenses,it depends rain or snow on windward slopes
Answer:
a. As vapor condenses, it depends (specifically; leads to) rain or snow on the windward slope
Explanation:
The orographic effect which is the changes in masses of air as it moves along the mountain sides, up or down is the way the mountains have an effect on the climate
The orographic effect of mountains can be analyzed based on either the windward side, (which is the side that faces the incoming wind), or the leeward side (which is the opposite side of the mountain)
The moist and warm air from the oceans and other large water bodies are carried by wind onto the mountains where the moist wind is directed upward by the obstructing mountain wall.
As the elevation of the warm moist wind increases along the mountain, the cooler temperatures at the high altitudes forces the air to cool down, until the dew point is reached, which leads to precipitation of rain or snow.
