Stomata and Transpiration on edmentum
Explanation:
Two groups of tomatoes were grown in the laboratory, one with humus added to the soil and the other a control without humus. The leaves of the plants grown without humus were yellowish (less green) compared with those of the plants grown in humus-enriched soil. The best explanation for this difference is that __________.
Answer:
The best explanation for this difference is that the humus contained micronutrients needed by the plants for the synthesis of chlorophyll, such as Manganese (Mn), Iron (Fe) and Copper (Cu).
Explanation:
Chlorosis is the yellowing of plant leaves, and this is due to the deficiency in the amount of chlorophyll contained in the plant leaves. Iron (Fe) is an essential micronutrient for the synthesis of chlorophyll, which is an enzyme-catalyzed reaction. Copper (Cu) is a component of most enzymes, while Manganese (Mn) is a cofactor, required for the activation of the enzymes that catalyze chlorophyll synthesis, hence deficiency of these nutrients will result in the development of chlorosis.
Which of the following is NOT a function of receptors?
Answer:
Receptors they receive signal an initiate a response that send a specific signal onward.
Explanation:
Receptors is performed may be affected environmental factors, like light, temperature, pressure, or other receptors.
Receptors can to be change the conformation and posture response to chemical reactions by called signaling.
Most receptors the cellular parts located the part of reporter outside of the cell.
Receptor and often alter the receptor conformation, and are found membrane, and receptor are located only inside the cell.
Receptor cellular control the functions such gene transcription.
Receptor can induce growth, and death, control channels or the regulate cell, and the cell receptors depends on the type of receptors expressed.
Answer: *Olfactory receptor, taste receptor, thermoreceptors are the receptors used for the senses of smell, taste and perceive temperature stimuli. *Photoreceptors are the receptors used to detect light. They are found in rods and cones of the retina in the eye. *Pain receptors sense the pain in parts of the body.Mar 18, 2015

TLRs are Group of answer choices the coatings of pathogens by complement. present in intact skin, sebum, tears, etc. phagocyte receptors that detect PAMPs. nonspecific leukocytes that secrete toxins onto the surface of virally infected cells. molecules that damage cells, resulting in cell lysis.
Answer: Phagocyte receptors that detect PAMPs
Explanation:
TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)
In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses.
what has a greater influence on protien levels
Question is incomplete, The complete question is as follows:
What has a greater influence on protein levels?
A. Protein degradation has a greater influence because they are denatured faster than the cell can produce them
B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced
C. mRNA destroyer concentration has a greater influence because mRNA is destroyed right after the proteins are produced
D. Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from
Answer:
B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced
Explanation:
mRNA destroyer concentration has a greater influence on protein levels because mRNA destroyers abort the mRNA as soon as the enough mRNA are produced before formation of proteins.
mRNA destroyer follow the mRNA around itself and dragged it once mRNA is picked for protein synthesis.
Hence, the correct answer is "B".

Elodea is a plant that lives in water. Like all plants, elodea can make its own food through
process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of
photosynthesis, a piece of elodea can be placed in an inverted test tube filled with a
sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.
A student has designed an experiment using elodea plants. The experimental setup is
shown in Figure 1-4
Which of the setups would serve as the control of the experiment?
Bucket
Lamp
Flashlight High
Natural
Elodea
Sodium
bicarbonate
solution
The controlled variable is kept constant during the whole experiment in all the different study groups. In this experiment, Sodium bicarbonate solution is the controlled variable.
------------------------
During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment,
The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variable → Sodium bicarbonate solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.-----------------------

Which of the following will cause a decrease in the mass of an object? A. Increase in the gravitational pull B. Decrease in the gravitational pull C. Increase in the quantity of substance present in the object D. Decrease in the quantity of substance present in the object
Answer:
C
Explanation:
Food moved to the back of the mouth by the tongue causes all of the following EXCEPT covering the opening of the larynx by the epiglottis. pressure against the pharynx to initiate swallowing. elevation of the soft palate to seal off the nasal cavity. the swallowing center stimulates successive waves of muscle contraction in the esophagus. churning of the stomach contents.
Answer:
churning of the stomach contents.
Explanation:
When food is moved to the back of the mouth by the tongue (deglutition), it does not cause the churning of the stomach contents.
The churning of stomach contents occurs when the bolus from the mouth has entered through the lower esophageal sphincter into the stomach. Churning is the mixing of the bolus with digestive juices containing acids and enzymes secreted from the stomach lining.
