Neurons, as with other excitable cells in the body, have two major physiological properties: ____________ and ____________. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the ____________. This system moves ____________ out of the cell and ____________ into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of ____________, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Answer:
Neurons, as with other excitable cells in the body, have two major physiological properties: irritability and conductivity. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the sodium potassium pump. This system moves sodium (Na+) out of the cell and potassium (K+) into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of intracellular proteins, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Explanation:
Neurons are cells with the capacity to transmit information between one another and also with other tissues in the body. This information is transmitted thanks to the release of substances called neurotransmitters, and this transmission is possible due to the electrical properties of the neurons.
For the neurons (and other excitable cells, such as cardiac muscle cells) to be capable of conducting the changes in their membranes' voltages, they need to have a resting membrane potential, which consists of a specific voltage that is given because of the electrical nature of both the inside and the outside of the cell. The inside of the cell is negatively charged, while the outside is positively charged - this is what generates the resting membrane potential. When the membrane voltage changes because the inside of the cell is becoming less negative, the neuron is being excited and - if this excitation reaches a threshold - an action potential will be fired. But how does the voltage changes? This happens because the distribution of ions in the intracellular and extracellular fluids is very dissimilar and when the sodium channels in the cell membrane are opened (because of an external stimulus), sodium enters the cell rapidly to balance out the difference in this ion concentration. The sudden influx of this positively-charged ion is what makes the inside of the neuron become less negative. This event is called depolarization of the membrane.

A researcher studying a line of cancer cells notices that cellular content of RhoBTB3 and Cyclin E1 increase and decrease through the cell cycle.
a. He hypothesizes that RhoBTB3 signaling regulates the production of Cyclin E1 and the entry of the cell into mitosis. Based on the data below, explain why his results do not support this hypothesis. Identify what conclusions are supported by this data.
b. Suppose that the researcher can engineer a cell line in which RhoBTB3 expression can be induced by the addition of a drug. Design an experiment using this cell line to test whether RhoBTB3 regulates the production of Cyclin E1. Describe what results he can expect if his hypothesis is correct.
I'm not sure about part b but here's the answer for part a
Explanation:
The experimental data shows that the RhoBTB3 expression increased after 12 hours and reached it's peak at 18 hours, which occurs in the G2 phase. The expression of Cyclin E1, however, started to increase after 8 hours, peaked at 14 hours, and remained there for 2 more hours before starting to decline. This shows that the highest level of the Cyclin E1 expression occurred in the S phase and initiated at the end of the G1 phase. His hypothesis is incorrect because if RhoBTB3 signaling did regulate the production of Cyclin E1, then the peak should have occurred prior to Cyclin E1.

How do interdependent factors—such as climate and lack of resources—impact the carrying capacity of an ecosystem?
Answer:
Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. If this helps you could I possibly have brainliest?
Explanation:
The impact of climate and lack of resources on the carrying capacity of an ecosystem is discussed below :
The carrying capacity of an ecosystem can be described as the maximum amount of organisms which can be naturally catered for giving the resources available in an environment.
Climate has an important role to play in the type of resource available or resources which can thrive in an environment. Similarly harsh climate conditions aren't favorable for survival, hence resulting in low carrying capacity of such ecosystem.
Also, organisms, animals depend on the available resources available in an environment for survival, when the available resources aren't enough to cater for a large population, the carrying capacity of the ecosystem is impeded.

Consider a hypothetical scenario in which the genes that determine body color, eye color, and wing type in fruit flies occur on the same chromosome. To determine the order of the three genes on the chromosome, a researcher looks at hundreds of flies and makes these observations: 90% of flies with red eyes have curly wings. 75% of flies with red eyes have black bodies, whereas the remaining 25% have brown bodies. 1% of flies have curly wings, white eyes, and black bodies. Based on these observations, what is the most probable location of each gene on the given chromosome
Answer:
The most probable location on the chromosome of each gene is:
wing shape gene ------- eye color gene -------- body color gene
Explanation:
To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.
By comparing the parental and the double recombinant we will realize which is the allele that changes in position. The position of this gene is in the middle of the other two genes because in a double recombinant only the central gene changes position in the chromatid.
So, according to this knowledge and the available information in the problem we can estimate the position of the genes in the chromosome.
Phenotypic proportions:
90% of flies with red eyes have curly wings (Parental)75% of flies with red eyes have black bodies (Simple recombinant)25% of flies with red eyes have brown bodies (Simple recombinant)1% of flies have curly wings, white eyes, and black bodies (Double recombinant)90% of individuals are red-eyed and curly-winged. This is a high frequency, which means that this is the parental phenotype. The other parental phenotype must be white eyes and straight wings.
Flies with curly wings, white eyes, and black bodies represent the lower proportion (1%) so this phenotype must be the double recombinant.
Flies with red eyes and black bodies, and flyes with red eyes and brown bodies are intermediate in proportion, so they must be simple recombinant phenotypes.
Parental)
Red, Curly
White, Straight
Double recombinant)
White, Curly, Black
Red, Straight, Brown
Simple recombinant)
Red, Black
Red, Brown
In the chromatid, there are two regions, Region 1 (from the first gene to the gene in the middle), and region 2 (from the gene in the middle to the gene of the other extreme).
The fact that both simple recombinants are red, tells us that the eye color gene and the body color gene are together, and the recombination occurred either in region 1 or 2.
We know that the double recombinant is White, Curly, Black. We also know that the eye color gene and the body color gene are together, so one of these two must be in the middle.
Parentals are red and curly, which means that the eye color gene and wing shape gene are also together. This leads us to assume that the eye color gene is in the middle.
Finally, the fact that the double recombinant is White, Curly, Black, and knowing that the eye color is in the middle and that both the extreme alleles change position, we can assume that the parental Red, Curly is also black, while the other parental is white, straight and brown. So:
Parental)Curly ------ Red ------Black (90%)
Straight ----- White ----- Brown
Simple recombinant)Curly -----White-----Brown
Straight-----Red -----Black (75%)
Curly----Red-----Brown (25%)
Straight ----White-----Black
Double recombinant)Curly-----White------Black (1%)
Straight----Red------Brown

3. Consists of keratinized stratified squamous epithelium.
4. Found lining the digestive and respiratory tracts.
5. Makes up the pleura and pericardium.
6. Lines blood vessels and the heart.
Answer:
Some of these sentences both refer to the same term.
1. The epithelial membrane that lines the closed ventral cavities of the body. - 5. Makes up the pleura and pericardium. This is called the serous membrane.
2. The epithelial membrane that lines body cavities open to the exterior membrane . - 4. Found lining the digestive and respiratory tracts. These statements refer to the mucous membrane.
3. Consists of keratinized stratified squamous epithelium. - cutaneous membrane.
6. Lines blood vessels and the heart. - endothelium.
Explanation:
All of these membranes are formed by epithelial tissue - one of the four basic tissues found in the human body, with important tasks that many times give the organs they're part of their main function.
The epithelium can vary in shape and size in order to adapt to the necessities of the organ. If the organ needs protection from abrasions, like the skin or the stomach, this tissue will have many layers and be called "stratified epithelium". On the other hand, an organ with the function to exchange substances, like the blood vessels or the alveoli, will have only one layer of epithelium, to ease the diffusion of gases and other molecules.
The other three basic tissues are: connective tissue, muscle tissue, and nervous tissue.

b. Both are composed of cells, ground substance, and protein fibers.
c. Neither of them provide protection as a main function.
d. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matric
Answer:
d. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matric
Explanation:
There are four primary types of tissues in living organisms. Epithelial and connective tissues are two of those four types of tissues. Epithelial tissues are made up of closely packed cells that serve functions such as absorption, secretion, protection, etc while connective tissues are composed of cells, ground substance, and protein fibers that serve supportive functions.
The cells of epithelial tissues are so closely packed to one another that there is hardly space in their extracellular matrix for materials. However, on the contrary, connective tissues are made up of cells that have room for large quantities of extracellular matrix. Hence, the cells that make up connective tissues are dispersed into matrix.
