why do both plant and animal cells have membranes

Answers

Answer 1

Both plant and animal cells have membranes so whatever chemical reactions they have going inside the cell, it is regulated and maintained. Membranes help separate the internal environment from the external environment.

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.

Answers

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.

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

Answers

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.

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

Answers

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

Georgia has hypochondriasis, and Leo has a pain disorder. Which of the following do Georgia and Leo most likely
have in common?
O a history of normal medical exams
O significant pain in a specific area
O a preoccupation with the idea of being sick
O an onset of the disorder before the age of 30

Answers

Answer:

C. a preoccupation with the idea of being sick

Explanation:

Hypochondriasis and pain disorder are two conditions that deviates from the normal human health. Hypochondriasis, also known as health anxiety, is a condition whereby an individual is fearfully worried about having a serious illness. On the other hand, pain disorder is a condition in which pain results in certain areas of an individual's body due to psychological disposition of such individual i.e. his/her mindset.

Based on the description of both conditions above, it can be observed that both hypochondriasis and pain disorder are as a result of a preoccupied mindset of being sick. One is worried PSYCHOLOGICALLY about being terribly ill (Hypochondriasis) while the other PSYCHOLOGICALLY induces pain on him/herself.

Carbohydrates is defined as biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1. Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle. [tex]Cn(H2O)n[/tex] is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.

Basically, the terms carbohydrate was used to describe compounds that have really contains carbohydrates. Because they had simple formula [tex]CH20[/tex]. In modern Era carbohydrates are classified on the basis of their structure not on their formulae. Such as aldehydes and ketones are now known as polyhydroxy.

Therefore, the carbon dioxide is the gas molecule most likely in the dough. Thus, option C is correct.
