I agree with this claim because organisms interact with one another in an ecosystem, thereby regulating population sizes in the community.
The Serengeti Rules is a documentary film based on biologist Sean B. Carroll's book (2017). This book explains the balanced functioning of an ecosystem by exploring the discoveries of five pioneering scientists: Mary Power, Bob Paine, Tony Sinclair, John Terborgh, and Jim Estes.
The term 'Serengeti rules' is due to many of these rules were obtained by studying natural populations in the Serengeti National Park (Tanzania).
These rules are a set of simple ecological rules of nature that indicate how ecosystems work.
The Serengeti rules explain how organisms interact with one another in the ecosystem, thereby regulating population sizes in the community.
Some key concepts of the Serengeti rules are as follow: Keynote species is a type of species whose activities govern the wellbeing of other species in the ecosystem. A trophic cascade is a phenomenon by which species impact other species even when they do not directly interact with each other. Downgrading refers to cascading effect of the removal of a species at the top of a food web (e.g., predators)

By the early 1980s, the population of Florida panthers had dwindled to fewer than 30. Furthermore, within this population was a high frequency of detrimental traits, including low sperm count and undescended testicles in males, and kinked tails in both sexes. The future for this iconic population was bleak at best. Provide an explanation for the observed detrimental traits. Provide a possible solution that would both increase the likelihood that the population would survive and preserve the genetic identity of this unique population.
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
What do spindle fiber and flagella have in common:
Select one:
a. They are examples on a structure called a microfilaments
b. They are all structures found in prokaryotic cells
c. They are microtubules
d. They are found in the nuclei of eukaryotic cells
Answer: c
Explanation: Spindle fiber: is a microtubules that comes out from the centrosomes when the cell is preparing for division. They are responsible for the segregation of sister chromatids and movement of chromosomes during mitotic and meiotic division.
Flagella: a slender threadlike structure, especially a microscopic appendage that enables many protozoa, bacteria, spermatozoa, etc. to swim.The thread-like structure is called chromosomes.
This can conclude that microtubules are common in spindle fiber and flagella.

Orangutans evolved from an ancestor they share with gorillas is true regarding primate family tree diagram. This means that orangutans and gorillas have a common ancestor. Option C is the correct answer.
Evolution is the process through which species change over time. It occurs through the accumulation of genetic variations and natural selection. The primate family tree shows the evolutionary relationships between different primate species, including orangutans and gorillas. Option C is the correct answer.
Orangutans and gorillas share a common ancestor in their evolutionary history. This means that at some point in the past, there was a species that gave rise to both orangutans and gorillas. Over time, as the common ancestor of orangutans and gorillas diverged into separate lineages, each species developed its own unique traits and characteristics. Despite their distinct characteristics, orangutans and gorillas still share certain genetic similarities due to their common ancestry. These similarities can be observed in their DNA sequences.

The complete oxidation of one glucose molecule yields 30 or more ATP . Glucose catabolism includes glycolysis, pyruvate oxidation, and the citric acid cycle. The total yield of ATP includes ATP , GTP , and reduced cofactors that yield ATP from the electron transport chain and oxidative phosphorylation. Which processes yield the most ATP
Answer:
Electron transport chain.
Explanation:
Electron transport chain is the process which yield the most number of ATP as compared to all three major phases of cellular respiration. Glycolysis produces only 2 ATP from the breakdown of molecule of glucose. In the Krebs cycle, one GTP which is an ATP equivalent is produced from the breakdown of one glucose molecule while on the other hand, 32 ATP molecules are produced from the breakdown of one glucose molecule.

In April 1990, the El Paso County (Colorado) Health Department recognized an outbreak of drug-resistant gonorrhea in Colorado Springs. 56 cases of penicillin- resistant Neisseria gonorrheae occurred from December 1989 through March 1991. To gather information about the outbreak, 410 persons related through a densely connected set of social or sexual associations were interviewed. What can public health workers tell individuals in this network to stop the spread of Gonorrhea in this population?
a) Preventive treatment with penicillin will prevent Gonorrhea infection in individuals not already infected.
b) Only individuals with symptoms should seek medical screening since all cases of Gonorrhea are associated with symptoms.
c) Condoms will not prevent the spread of Gonorrhea. Gonorrhea can spread from an infected mother to a fetus.
d) Gonorrhea is more prevalent in individuals 24 years and older.
Answer:
c) Condoms will not prevent the spread of Gonorrhea. Gonorrhea can spread from an infected mother to a fetus.
Explanation:
To prevent the spread of infection, it is important that healthcare professionals inform people about ways to protect themselves against infection. In addition, it is important that health professionals inform the dangers that this infection can cause, such as symptoms and rapid transmission, which can even happen from mother to fetus. On how to protect themselves, health professionals can say that the use of condoms is the most efficient form of protection.
Which of the following characteristics are shared by all living organisms
Answer:
Cells
Explanation:
They have cells
What is a living cell?
Answer:
Though they are often debated, there are eight main characteristics that define a cell as living.
The first is genetic code. All living things contain DNA, which is like the instruction manual for life. DNA is contained in each cell, and passed from parent to offspring.
The second is growth and development. Whether by creating more cells or creating more organelles within the cell, all living things grow and develop.
The third characteristic is reproduction. Reproduction can be sexual or asexual, but in the case of single cells, it is asexual.
The fourth characteristic is response. All living things, including cells, react to external stimuli, such as temperature or salinity.
The fifth characteristic is homeostasis. Homeostasis is the condition by which living things maintain a stable internal environment in the midst of an ever-changing external environment.
The last three characteristics go hand in hand, and are sometimes combined, but in my mind they are distinctly separate.
Sixth is consumption, which is taking in food and other materials. A cell specifically takes in molecules such as water or glucose during consumption.
Seventh is metabolism, which is using materials consumed in order to create energy. Living cells use enzymes to break down materials to produce ATP (adenosine triphosphate), which is usable energy.
Finally, all living cells undergo excretion in some form. Some examples in cells include exocytosis and osmosis.
These 8 characteristics, though often controversial, determine a cell as living.

Contrast the usefulness of absolute and relative dating techniques.
Answer:
In relative dating, fossils are dated according to the depth at which they were buried While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils.
Why do i only have one dimple on my left cheek?
Answer:
A single dimple on one cheek is a rare phenomenon. Transfer of dimples from parents to children occurs due to just one gene. The dimple creating genes are present in the sex cells prior to the process of reproduction. Each parent provides one of these genes to the child.
Which of the following effectively describes the situation of someone with an inherited predisposition to cancer such a familial adenomatous polyposis or BRCA-associated familial breast cancer?
a) Every cell of their body contains a gain-of-function allele of an oncogene
b) Most cells in their body contain multiple cancer-causing mutations
c) If they get malignant cancer, somatic mutations will not have been a factor
d) Their cancer will most likely arise in their germ cells, not their somatic cells
e) None of the answers effectively describes the situation
f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene
Answer:
Every cell of their body contains defective , loss of function allele of a tumor suppressor gene
Explanation:
Tumor suppressor genes - They encode Proteins that inhibit cell proliferation . But due to Loss of functional alleles in Tumor suppressor genes it leads to the development of different cancers
Every cell of the body comprises of a defective and loss-of-function allele of a tumor suppressor gene.
The presence of defective and non-functioning tumor suppressor gene is responsible for the happening of cancer disease because the tumor suppressor gene slow down the process of cell division as well as repair mistakes occur in DNA molecule. When the tumor suppressor genes can't perform its function properly, it causes out of control growth of cell, which can lead to cancer disease so we can conclude that tumor suppressor gene is responsible for the cancer disease.

2. Calculate the rate of population increase for the whales and the seals from the data in table 2, trial 1. What does this rate represent?
Hint: From the point of zero change on the graph to the highest population achieved is a change in time of 100 months. (Refer to the science skills practice in the lesson for the correct formula for the rate of population change.)
Answer:
There are no tables but it should be a bell curve. as a population of whales rise the population of seals will decrease, eventually creating a plateau in the whale population. shortly after the plateau in the whale population the whale population will begin to decline ( as food becomes less available) causing the seal population will begin to rise and restabilize. this pattern should continue cyclically creating a wave function on a graph!
