Explanation:

Megalodon left an awful lot of teeth behind, but don't worry. It is likely that it had plenty of extras. Like modern sharks, Megalodon had several rows of teeth. Scientists believe that Megalodon had six rows of 7-inch-wide, razor-sharp teeth, top and bottom, for a total of 276 teeth in its giant jaws! It's no wonder, then, that this ancient shark left so many of them behind. Without this trail of teeth, we would not know that these enormous creatures swam the ancient oceans as a top predator.Select two sentences from below that best show that the author wants the reader to be able to relate Megalodon's size to everyday life




A.What would you expect a creature whose name means “big tooth” to look like?
B.The Megalodon shark deserves this title.
C.As the Greek roots mega- (“big”) and don (“tooth”) suggest, this awesome prehistoric creature certainly did have huge teeth—as well as a massive and powerful body.
D.Scientists estimate that these gigantic sharks stretched as long as 60 feet.
E.If you're having trouble imagining that, just think of a school bus, typically about 45 feet in length.
F.Now, imagine a shark just a bit larger than that school bus—with 7-inch teeth.
G.Yes, this ancient fish certainly earned the prefix mega!
H.Since these sharks are extinct, how do we know exactly how huge and powerful the Megalodon shark was?

Bacterial disease is caused by the multiplication of bacteria in a patient. How do pathogenic bacteria harm a patient?

Answers

Answer:

Host Susceptibility

Resistance to bacterial infections is enhanced by phagocytic cells and an intact immune system. Initial resistance is due to nonspecific mechanisms. Specific immunity develops over time. Susceptibility to some infections is higher in the very young and the very old and in immunosuppressed patients.

Bacterial Infectivity

Bacterial infectivity results from a disturbance in the balance between bacterial virulence and host resistance. The “objective” of bacteria is to multiply rather than to cause disease; it is in the best interest of the bacteria not to kill the host.

Host Resistance

Numerous physical and chemical attributes of the host protect against bacterial infection. These defenses include the antibacterial factors in secretions covering mucosal surfaces and rapid rate of replacement of skin and mucosal epithelial cells. Once the surface of the body is penetrated, bacteria encounter an environment virtually devoid of free iron needed for growth, which requires many of them to scavenge for this essential element. Bacteria invading tissues encounter phagocytic cells that recognize them as foreign, and through a complex signaling mechanism involving interleukins, eicosanoids, and complement, mediate an inflammatory response in which many lymphoid cells participate.

Genetic and Molecular Basis for Virulence

Bacterial virulence factors may be encoded on chromosomal, plasmid, transposon, or temperate bacteriophage DNA; virulence factor genes on transposons or temperate bacteriophage DNA may integrate into the bacterial chromosome.

Host-mediated Pathogenesis

In certain infections (e.g., tuberculosis), tissue damage results from the toxic mediators released by lymphoid cells rather than from bacterial toxins.

Intracellular Growth

Some bacteria (e.g., Rickettsia species) can grow only within eukaryotic cells, whereas others (e.g., Salmonella species) invade cells but do not require them for growth. Most pathogenic bacteria multiply in tissue fluids and not in host cells.

Virulence Factors

Virulence factors help bacteria to (1) invade the host, (2) cause disease, and (3) evade host defenses. The following are types of virulence factors:

Adherence Factors: Many pathogenic bacteria colonize mucosal sites by using pili (fimbriae) to adhere to cells.

Invasion Factors: Surface components that allow the bacterium to invade host cells can be encoded on plasmids, but more often are on the chromosome.

Capsules: Many bacteria are surrounded by capsules that protect them from opsonization and phagocytosis.

Endotoxins: The lipopolysaccharide endotoxins on Gram-negative bacteria cause fever, changes in blood pressure, inflammation, lethal shock, and many other toxic events.

Exotoxins: Exotoxins include several types of protein toxins and enzymes produced and/or secreted from pathogenic bacteria. Major categories include cytotoxins, neurotoxins, and enterotoxins.

Siderophores: Siderophores are iron-binding factors that allow some bacteria to compete with the host for iron, which is bound to hemoglobin, transferrin, and lactoferrin.

PLEASE HELP ME WITH 10 and 11!! :(

Answers

Answer:

Please find the answers to numbers 10 and 11 of the attached image below.

Explanation:

10. This question lists the stages of mitosis namely: prophase, metaphase, anaphase, and telophase. The major events that take place in each of these stages are as follows:

A) PROPHASE:

- the supercoiled chromosomes known as chromatin begins to condense making it visible.

- spindle begins to emerge from the centrosome organelle.

- Nuclear envelope begins to break down in order to expose the chromosomes in the nucleus.

B) METAPHASE:

- The chromosome are aligned at the cell plate i.e. the equator/middle of the cell.

C) ANAPHASE:

- The sister chromatids of each chromosome i.e. replicated chromosomes are pulled apart at the centromere by spindle microtubules to the opposite poles of the cell.

D) TELOPHASE:

- Chromosomes at opposite poles begin to decondense into chromatin.

- The nuclear envelope reforms around the chromosomes

11) Cytokinesis is the process that occurs after mitosis (nuclear division). It is the process whereby the cell whose chromosomes are now separated into opposite poles divide into two. In other words, a cell divides into two in the cytokinesis stage.

stop condon mutation

Explanation:

The mutation is defined as the alteration or change in the genetic sequence of the chromosome. The mutations in the ADA genes have been noted and are caused by point mutations.

Point mutations are defined as the mutations in which the alteration of the single nucleotide of DNA occurs.

Stop codon mutations are the type of point mutations, in which the nonsense codons signal the end of protein synthesis.

Adenosine deaminase is involved in purine metabolism. It is involved in the development of the immune system.

Lucy's condition is due to the stop codon mutations in the genetic sequence of the DNA. The stop codon mutation will signal the end of the translation process, which will result in the non-functionality of the ADA enzyme.

Therefore, the stop codon mutation in the ADA enzyme will occur in Lucy's genetic sequence.

To know more about the ADA enzyme, refer to the following link:

Antimycin A Antimycin A is used in catfish farming: added to the water at 10 ppb, it kills small fish but does not harm catfish. Thus, small fish die out, and catfish get all the resources. When Antimycin A is added to isolated mitochondria, NADH and succinate both accumulate. However, if ascorbate, an artificial redox mediator that transfers electrons to cytochrome c, is added, oxygen consumption is still observed. Which step in the respiratory chain is antimycin A likely to inhibit (1 pt)

Answers

Answer:

Inhibits electron transport chain in mitochondria.

Explanation:

Antimycin A inhibits electron transport chain which leads to the complete halt of electron transport in mitochondria. due to this inhibition of electron transport chain in mitochondria leads to the killing of the fishes except catfish and so the catfish increase in population due to more resources and no competition. this Antimycin A is highly toxic for fishes and kill all fishes if used at the amount of 10 ppb.

How are the processes of cellular respiration, photosynthesis and carbon cycle related to each other?

Explain how one of the processes discussed in this module (photosynthesis, cellular respiration or the carbon cycle) apply to both the Law of Conservation of Matter and Law of Conservation of Energy.

Answers

Answer:

1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.

2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!

3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

Explanation:

Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.

Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
