A water strider (which can walk on water)has legs that are coated with a hydrophobic substance. What might be the benefit? What would happen if the substance were hydrophilic?

Answers

Answer 1

Answer:

The water striders are the species, which are about half an inch in length and exhibiting a thin body with three legs set. The legs of water striders exhibit small hairs, which helps in repelling water and holding air. The water striders by repelling water stand on the surface of the water and the captivated air permit them to float and move readily.  

The legs of water striders are coated with hydrophobic substances, which helps in repelling water and assists in keeping the terminals of the legs from getting coated with water. In case, if the legs of the species were coated with a hydrophilic substance, then water would be drawn up by the legs and would make the striders break through the surface and thus would have a tough time to walk on water.

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.

Answers

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.

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

Answers

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 variableSodium  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 sequences is correct for the downhill movement of electrons during cellular respiration? A. glucose – citric acid – ATP – NAD+ B. glucose – NADH – electron transport – O2 C. glucose – pyruvate – ATP - oxygen D. glucose – ATP – electron transport - NADH E. glucose – Kreb’s cycle – NADH - ATP

Answers

Answer:

B. glucose – NADH – electron transport – O2

Explanation:

This is the sequence  from glycolysis in which  glucose molecules are split down to pyruvate, to oxidative phosphorylation.

During this process the electrons are released from glucose  molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .

The makes the  carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .

The electrons from above are  transferred in hydrogen atoms  to matrix by these co-enzymes.Where the H is split to electrons  and protons.

The electrons for the ETC, produce the PMF for transporting  protons into the intramembrane space.

The concentration of protons generated the electrochemical gradients  which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.

The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.

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.

Answers

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.

Explain why stem cell research is a controversial subject. What are some of the sources for stem cells?

Answers

Answer:

Stem cell research is a controversial subject because they are human embryonic stem cell (hESC), and obtaining stem cells involves the destruction of human embryos

Explanation:

The inner cell mass of a 5 to 7-day-old blastocyst can be used to generate pluripotent stem cell lines. Human embryonic stem cell investigation, on the other hand, is morally and politically fraught since it encompasses the killing of human embryos.

What are stem cells?

Stem cells are the primary raw material of the body, the cells that give rise to every other cells with specialized functions.

Under the right circumstances, stem cells differentiate to form the most cells known as daughter cells in the body or in a research lab.

Stem cells are mostly found in bone marrow. This is how they divide in order to produce new blood cells.

Once mature, blood cells end up leaving the bone marrow and reach the bloodstream. A small number of immature stem cells enter the bloodstream.

Bone Marrow has long been thought to be the best source of stem cells.

Previously, if a patient required a stem cell transplant but didn't have access to umbilical cord blood stem cells, they earned a bone marrow transplant.

Thus, this is the reason to have stem cell research as a controversial subject.

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 __________.

Answers

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.
