when water gets the leaves,
it evaporates & turns into water vapor.
this is called
"evapotranspiration"
a combination
transpiration & evaporation
water vapor diffuses out of the leaves

The water that leaves the plant through transpiration helps to regulate the temperature of the plant, transport nutrients and minerals, and provide the necessary moisture for photosynthesis.
The process of transpiration is influenced by environmental factors such as temperature, humidity, and wind, as well as by the physiology of the plant itself.
So, in summary, transpiration is a crucial process in the life of a plant as it helps it to obtain and circulate water and nutrients throughout the plant, while also regulating its internal temperature.

Why a virus can only infect specific cells and organisms?
Only specific species of hosts and subsets of those hosts' cells are susceptible to virus infection. The virus can only bind to the host cell surface if a certain surface molecule known as the viral receptor.
Viruses can be thought of as obligate intracellular parasites. In order to infect other cells and ultimately other people, the virus needs to adhere to a living cell, enter the cell, make its proteins and replicate its genome, and then find a means to leave the cell. Only specific species of hosts and subsets of those hosts' cells are susceptible to virus infection. The virus must be producing the materials it requires in the cell, such as the enzymes for which the virus genome lacks the necessary genes.

as pressure increases in lymphatic capillaries, fluid is allowed to regurgitate back into the tissues, true or false?
True. The lymphatic capillaries are very thin-walled vessels that transport lymph (a clear fluid containing immune cells and waste products) from the interstitial spaces of tissues back into the bloodstream. The capillaries have one-way valves that prevent the backflow of lymph, but they can be overwhelmed by high pressure within the capillaries.
What happens If the pressure in the lymphatic capillaries increases?If the pressure in the lymphatic capillaries increases, due to increased volume or decreased drainage capacity, the one-way valves may not be able to close completely, and fluid can regurgitate back into the tissues. This can result in the accumulation of interstitial fluid and edema (swelling), which can cause discomfort and impair tissue function.
The regurgitation of fluid back into the tissues can also occur if the lymphatic vessels are damaged or removed, such as during surgery, radiation therapy, or infection. In such cases, the lymphatic system may be unable to drain fluid effectively, leading to chronic edema and tissue damage.

13) what kind of protein is used as a detector to probe the target protein?
The type of protein used as a detector to probe the target protein can vary depending on the specific application and detection method being used.
In general, the detector protein should have a high affinity and specificity for the target protein so that it can bind to it selectively and with a high degree of sensitivity.
Commonly used detector proteins in various types of protein assays include antibodies, which can recognize specific epitopes on the target protein, and protein tags, which can be fused to the target protein to enable detection using complementary probes or ligands.
Other types of detector proteins include lectins, which can bind to specific carbohydrate residues on the target protein, and biotin-binding proteins, which can bind to biotinylated target proteins. In addition, some assays use fluorescent or luminescent proteins, such as green fluorescent protein (GFP), as detector proteins to enable direct visualization of the target protein.

in the traditionally accepted model of upr initiation, What activates the UPR?
The UPR is not engaged under normal circumstances, but it can become active in response to specific stimuli, like as hypoxia or altered glycosylation, because of a buildup of unfolded proteins.
The unfolded protein response is triggered by ER stress (UPR). Although the UPR works to reduce ER stress, it can potentially result in cell death if it is sustained. In the ER membrane, there are at least three ER stress sensors: IRE1, PERK, and ATF6.
The endoplasmic reticulum (ER) is a dynamic intracellular organelle that performs a variety of vital tasks for cellular growth, homeostasis, and stress resistance. Unfolded protein response (UPR), a well-known signalling cascade, is triggered in response to cellular stress. Three ER transmembrane proteins, Activator model, PKR-like ER kinase (PERK), and Inositol Requiring 1 (IRE1), start the UPR.

Erwin Chargaff determined that the number of ____ like guanine and adenine always equal the number of ____ like cytosine and thymine.
Erwin Chargaff discovered that the quantity of pyrimidines, such as cytosine and thymine, and purines, such as guanine and adenine, are always equal.
According to Chargaff's rules, DNA from every cell of any organism should have a ratio of 1:1 of purine and purine bases. More specifically, the amounts of guanine and adenine should be equal to nucleotides and thymine, respectively. This phrase alludes to the work of Columbia University biochemist Erwin Chargaff. DNA always includes equal amounts of guanine, cytosine, adenine, and thymine, according to Chargaff's analysis of the ratios of the four types of base units in the late 1940s. Moreover, there should be a 1:1 molar ratio ratio between the purine & pyrimidine bases (A+G=T+C). The nitrogenous bases adenine, thymine, cytosine, & guanine are all present in DNA. Both adenine and thymine always bind with cytosine, and vice versa. As some nucleotides are always found in pairs, their percentages in the DNA will be equal.

explain why the resting membrane potential is not equal to the k equilibrium potential.
The resting potential of a membrane is not equal to the K equilibrium potential as the membrane is depolarized and therefore it is going to have a more positive value than the K equilibrium potential.
What basically generates the resting membrane potential is the potassium ions which leak from the inside of a particular cell to the outside through leaky potassium channels and therefore generates a negative charge in the inside as compared to the outside. At rest, the membrane is impermeable to sodium ions and this is because all of the sodium ion channels are closed.
In a normal cell, the permeability of sodium ions is about 5% of the potassium ion permeability whereas the respective equilibrium potentials are +60 mV for sodium ( which is represented as ENa) and −90 mV for potassium (represented as EK). Thus, we can say that the membrane potential will not equal to EK but rather have a more positive value.

What is definition of zygote in biology?
In biology, a zygote is a single cell that is formed when a sperm cell fertilizes an egg cell. The zygote is the first cell of a new individual and contains all the genetic information necessary for the development of an organism.
After fertilization, the zygote undergoes a series of cell divisions, called mitosis, and develops into a multicellular embryo. As the embryo develops, cells differentiate and become specialized for specific functions, forming various tissues and organs. The zygote is diploid, meaning it contains two sets of chromosomes, one from each parent. The chromosomes carry genetic information in the form of genes, which determine an individual's physical and biological traits. The zygote is a crucial stage in sexual reproduction, as it combines genetic material from both parents and gives rise to a new individual. In some organisms, such as plants, the zygote can remain dormant for a period of time before developing into a new organism.

No tetrads will form during mitosis in the cells of an organism with a diploid chromosome number of 2n = 24.
Tetrads, or groups of four chromatids, are formed during meiosis when homologous chromosomes pair up and exchange genetic material in a process known as crossing over. During mitosis, however, the chromosomes condense and line up at the equator of the cell, then separate into two identical sets of chromosomes that are distributed to the daughter cells. Therefore, tetrads do not form during mitosis, but rather during meiosis I.
