does increasing the air temperature of fact the average number of hours a mouse sleeps per day?
Answer:
Hmmm... I'm no Expert when it comes to this, but I think it's safe to say yes.
Explanation:
From what I know, Mice and humans have around the same average body temperatures (Since we are both warm-blooded mammals).
One key difference between mice and humans when it comes to heat regulation is the topic of homeostasis and heat regulation.
Based on a study posted on FebsPress, "At ambient environmental temperature (~ 22 °C), over one‐third of energy expenditure in mice is devoted to maintaining core body temperature, largely by brown adipose tissue. To conserve this energy, mice can enter a regulated hypothermia, while humans do not." (Marc L. Reitman).
Since mice are so small, they have to work harder than a human or any larger mammal to maintain heat. This is also why they need to eat so much every day (to maintain a constant metabolic rate without starving themselves).
Now back to the key topic, "will air temperature affect the average number of hours a mouse sleeps per day?"
It is true that in humans, very low temperatures and very high temperatures can affect the sleep cycle because the body then has to exert more energy to maintain a comfortable internal body temperature.
Now, think back to what I said regarding the size of a mouse and what that means for it's metabolic rate.
This means, that too low/high air temperatures -- are likely to awaken the mouse or simply kill it. As one of the human body's goals is to maintain homeostasis, this goal is also evident in that of a mouse's body.
So, for the mouse to keep a consistent bodily temperature, it wouldn't sleep as long as a human, as mice have to eat at around their own body weight each day.
Note: Sorry for the length of this. I'd meant to keep it short and sweet but got caught up with the research. Haha.

Mecanismo de defensa de algunos animales que consiste en un aislamiento en cuevas o madrigueras durante los periodos desfavorables del año a Madriguera es verdadero o falso
Answer:
Responder:
CIERTO.
Explicación:
Este es un ejemplo de adaptaciones conductuales conocidas como adaptaciones anti-depredadoras. Esto es principalmente importante en áreas donde hay poca vegetación. Los búhos de madriguera, las tortugas que viven en los desiertos y las suricatas son ejemplos. Estos animales se encuentran en regiones de baja vegetación. Por lo tanto, no están protegidos de los depredadores. Por lo tanto, cavan profundo bajo tierra para escapar del depredador.
Además, debido a que estas regiones son principalmente áridas, los animales necesitan escapar de la alta temperatura y, por lo tanto, conservar el agua.
In your own words, explain what "the more mass a substance has, the greater the object's thermal energy" means.
A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?
Answer:
This question lacks options, the options are:
A) FF and ff
B) FF and Ff
C) Ff and Ff
D) Ff and ff
The answer is D (Ff and ff for parent 1 and 2 respectively)
Explanation:
This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.
According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.
To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).
In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.
Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).
Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.
Which correctly lists the three layers in which water moves easily? rock, clay, granite soil, rock, organic layer clay, organic layer, granite granite, rock, soil
Answer:
The correct option is;
soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer

A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?
Answer:
The average diffusion distance is 2.1 mm
Explanation:
Given
Diffusion distance of the four potato squares are;
[tex]Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm[/tex]
Required
Average Diffusion Distance
To calculate the average diffusion distance; we simply calculate the mean of the student recordings
Mean is calculated as thus;
[tex]Mean = \frac{\sum x}{n}[/tex]
Where x is the individual distance of the potato squares
[tex]\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm[/tex]
[tex]\sum x = 8.4mm[/tex]
n is the number of potato squares
n = 4
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]Mean = \frac{8.4 mm}{4}[/tex]
[tex]Mean = 2.1 mm[/tex]
Hence, the average diffusion distance is 2.1mm
How osmosis takes place in animal cell ?
Answer:
Osmosis in animal cells. animal cells have partially permeable cell membrane. animalcells are placed in pure water because their cytoplasm is a stronger solution than the pure water, water will pass into the cells by osmosis. The cells will therefore swell up.
Explanation:
Describe the movement of water molecules in this diagram and identify the state of the solution. Explain why the water molecules moved I bc this direction
Answer:
the answer is they move freely
Explanation:
Answer: The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration.
Explanation: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In the diagram shown, the solute cannot pass through the selectively permeable membrane, but the water can.
Which cell organelle underwent a change that caused this plant to wilt and droop? Which cell organelle helps the plant maintain its structure during such stress?Which condition is required for viruses to reproduce?
Answer: A vacuole undergoes a change in the plant causing wilting and droping.
Explanation:
The vacuole is an organelle, which is a store house of excess water and stored materials. During dehydration, the plant uses water from vacuole. Thus water and stored materials reservoirs get consumed up in this process, the plant experiences scarcity of water. This causes wilting and droping of plant.
The cell membrane is an envelop outside the cells, which causes plants to maintain their structure during stress for example, plant exposed to hypertonic solution. This prevents the cells to burst.
A virus require a living host. A host can be a plant, animal, human, or any other living organism. It does not have a cellular machinery thus uses host cell machinery to replicate its genetic material and produce its progeny.

I NEED HELP! If you had to pick a specific food that was high in potential energy to include in your diet, which food would you pick? Explain why this food is high in potential energy.
Answer:
I would choose Chicken or a Sugary beverage.
Explanation:
The potential energy in food is what we call a Calorie
Answer & Explanation:
Potential energy is the energy that can be utilized at a later date but is not being used at the moment. Many food molecules have potential, but the highest energy molecules are carbohydrates, which consist of sugars and starches primarily. Many foods that are high in carbs, such as fruits and grains, also have other benefits such as vitamins. If I was going to pick a particular food to include in my diet that contained carbohydrates, I would probably pick raspberries, since they have many health benefits besides being a quick source of energy. Also, it should be noted that simple carbs are not healthy at all, because they provide too easy a source of energy.
