Which statement is FALSE?Question 39 options: Water can hold an unlimited amount of oxygen. Water can hold less oxygen than air can. Underwater organisms need oxygen. A small decrease in dissolved oxygen can have an effect on aquatic life. Underwater organisms use oxygen in cellular respiration.

Answers

Answer: Water can hold an unlimited amount of oxygen.

Explanation:

Water cannot hold an unlimited amount of oxygen because it would get to a point where it is saturated as it needs to hold Hydrogen as well. Air on the other hand, has significantly more space for oxygen as it contains only 21% and can keep taking more.

Underwater organisms need oxygen for respiration and a small decrease in the oxygen available in water affects aquatic life because they rely on it to survive.

Describe the role chemical signals play a role in both the nervous system and the endocrine system

Answers

Like the nervous system, the endocrine system is a regulatory system. However, instead of using electrical impulses for signaling, it produces and uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
Neurotransmitters are often referred to as the body's chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles.

Bacteria species live in the intestinal tracts of many types of mammals. These bacteria consume the partially digested food the mammal eats but also help to complete digestion of the food for mammals. This represents a ________________ relationship between species.

A) Predation
B) Mutualistic
C) Competitive
D) Commensalism

Answers

Answer:

B) Mutualistic

Explanation:

A mutualistic relationship is one of the symbiotic relationships that involves two organisms whose actions benefit one another. In mutualism both parties interact with one another and gain from one another.

According to this question, a bacteria species live in the intestinal tracts of many types of mammals. The bacteria helps the mammal to completely digest the food while the mammal provides shelter and food for the bacteria. This represents an example of MUTUALISTIC RELATIONSHIP.

The behavior of allosteric enzymes a. does not play any role in feedback inhibition in metabolic pathways b. is strongly dependent on the presence of metal ions c. is related to their ability to hydrolyze themselves d. depends on changes in their quaternary structure on binding of substrates or inhibitors

Answers

Answer:

The correct answer is d

Explanation:

Allosteric enzymes have multiple binding sites to different ligands called allosteric sites (different from the active site), these ligands can modify their kinetic properties. They are generally made up of more than one polypeptide chain, and have a quaternary structure, an enzyme with a quaternary structure can bind more than one substrate molecule. An allosteric enzyme is an enzyme whose activity is regulated by an allosteric center, which is a site, other than the active center of the enzyme, to which a regulator (called an allosteric regulator) binds in a reversible and non-covalent manner. The binding of this regulator modifies the three-dimensional structure of the enzyme and affects the configuration of the active site, thus increasing or decreasing its activity, depending on the case. The allosteric sites present in regulatory enzymes is where allosteric effectors or inhibitors are attached, causing a conformational change in the substrate binding site or catalytic site, thus regulating enzyme activity.

Answer:

d. depends on changes in their quaternary structure on binding of substrates or inhibitors

Explanation:

Allosteric enzymes are oligomeric proteins composed of subunits or polypeptidic chains. They have a quaternary structure -many subunits and active sites- and express two states, R and T. Both states establish an equilibrium, with or without a joint ligand.

When the transition from one state to the other occurs, symmetry is conserved, but the affinity of a site to a ligand is altered. When a substrate joins one of the sites, it affects other binding sites.

Allosteric enzymes can change their conformation, exhibiting active and inactive conformations as a result of substrate binding at the activated center and regulatory molecules at other binding sites -allosteric centers-.

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation.

Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called sister chromatids. During metaphase, the X-shaped structure is called a metaphase chromosome, which is highly condensed and thus easiest to distinguish and study. In animal cells, chromosomes reach their highest compaction level in anaphase during chromosome segregation.

Sometimes the most practical way to do an experiment is not to perform it in an animal, but to look at cell responses in culture. Cells from mice, humans, and other mammals have been used to establish cell culture lines that have been very important for research. You are studying a novel water-soluble mouse hormone. You know cell culture can be a practical model to reveal protein function, so you apply the hormone to yeast cells, but nothing happens. What is a likely explanation for why nothing happened in your experiment

Answers

Answer:

Yeast cells likely do not have receptors that bind to this specific water-soluble mouse hormone

Explanation:

Receptors are molecules capable of binding specific signaling molecules (i.e., ligands). For example, steroid receptors can only bind to specific steroid hormones (e.g. estrogen, progesterone). Plasma membrane receptors are protein receptors that bind to water-soluble ligands. These receptors are embedded in the cell plasma membrane and usually contain several transmembrane domains. Examples of cell membrane receptors include G protein-coupled receptors (GPCRs), enzyme-linked protein receptors and ion channel receptors.

Stone Forest, China
Located in China you have blade-like pillars of limestone and sandstone, often over 10m tall. A wonderful landscape that looks parallel to a forest of stone is appropriately named the Stone Forest. The stone forest was constructed in a shallow sea about 270 million years ago. Sandstone and limestone compiled in the bay over time and were ultimately pushed upwards towards the sky. The rocks then began to be molded by wind and water of the surface to create the impressive and grand stone statues they are today.

Giant's Causeway
In Northern Ireland, exist over 40,000 enormous hexagonal black pillars each with some irregular sides, jutting out of the cliff. All of these irregular pillars mesh neatly together appearing as steps. They were established after volcanic eruptions about 50-60 million years ago during the Paleogene Period. It was assumed that the speed at which the lava cooled may have to do with the sizes and shapes of the columns. However, the volcano that was the cause of the columns can no longer be seen today, it has vanished due to erosion.

Ha Long Bay
There stands a glorious terrain formed of limestone pillars and caves located in Vietnam. The rocks have been forged by the sea falling and rising over an estimated 500 million years. The bay also consists of over 1600 islands, a large portion of which remain uninhabited. However, the handful of Islands that contain civilization are fishing villages with towns built on the water. According to the towns peoples stories, it was dragons that created the islands and pillars of rocks to protect Vietnam from invaders.

Biome Description Biome Name

This biome is characterized by long, cold winters. Plants living in this biome are adapted to the short summer growing season. Decomposition in this biome is slow, because of these low temperatures, high soil acidity, and a deep layer of needles from evergreen trees. ________________
In this biome, very little plant litter builds up on the ground because of the hordes of decomposers living here. Under these uniformly warm and humid conditions, the nutrients that are released by decomposers allow for quick uptake by producers, resulting in lush vegetation. ___________________
Although the average annual precipitation in this biome is quite high, rain falls only during certain times of the year. Grasses and widely scattered clumps of trees are the predominant vegetation, and they are well adapted to surviving alternating cycles of dry heat and heavy rains. _________________
Drought-resistant perennial grasses are the dominant vegetation in this biome, as there is sparse annual precipitation. Periodic natural fires, grazing, and drought typically eliminate most seedlings (which adds to the rich organic composition of the soil). Today, much of this land is devoted to farming, with annual crops such as corn and wheat replacing the natural perennial grasses. __________

This is most likely to: Group of answer choices Decrease the pumping of NADPH across the thylakoid membrane Increase the pH of the chloroplast stroma Decrease of flow of electrons from photosystem II to photosystem I Decrease the concentration of ATP in the thylakoid space

Answers

Answer:

Decrease the pumping of NADPH across the thylakoid membrane

Decrease of flow of electrons from photosystem II to photosystem I

Explanation:

Thylakoids are defined as a membrane-bound compartments located inside the chloroplasts and the cyanobacteria. Here, light-dependent reactions of photosynthesis occurs.

To block the photosynthesis process, the herbicides pushes the dichlorophenyl dimethylurea to block the electron flow through the photosynthesis II and it reduces the flow of electrons from photosystem II to photosystem I. It also decreases pumping of the NADPH across the thylakoid membrane.

Which of the following statements about proto-oncogenes is false? - Proto-oncogenes are normal genes with the potential to become oncogenes. A mutation must occur in a cell's DNA for a proto-oncogene to become an oncogene. Many proto-oncogenes code for growth factors. If a proto-oncogene's gene product is produced in smaller quantities, a cell may become cancerous.

Answers

Answer:

If a proto-oncogene's gene product is produced in smaller quantities, a cell may become cancerous.

Explanation:

The transformation of a cell to a malign cell occurs by mutations accumulation in some specific genes. These genes are grouped into two groups or families:

ProtooncogenesTumor suppressor genes

Protooncogenes direct the production of proteins of varying locations and functions that play a significant role in cell proliferation and differentiation. The proteins include cyclins, growth factors, receptors, etcetera. These genes are proteins codifiers and influence the cell cycle by favoring proliferation or inhibiting senescence and apoptosis.

Depending on the organism´s development stage, these genes can be physiologically active or reprimed.

Certain structural or functional changes in protooncogenes contribute to turning them into oncogenes. When protooncogenes mutate into oncogenes, they are capable of controlling cell multiplication and massively synthesize uncontrolled division triggers.
