Answer:
Challenge : Competition form other species.
Success : Adaptation and colonisation.
Explanation:
Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge. Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.If an alien astronomer in a distant galaxy looks at all the galaxies it can see, it will observe that Select one: a. other galaxies are moving away from it. b. half of the galaxies are moving away and half of them are moving toward it. c. other galaxies are stationary. d. other galaxies are moving toward it.

You are working to catalogue some of the species in the Amazon rainforest
before they become extinct from logging. You collect 3 organisms that all look
similar to the Coral snake and do a phylogenetic analysis on them before
classifying and naming them. The Coral snakes DNA barcode is
ATTCGCGATAC. Compare it to each sample organism's DNA barcode to
determine how related they are to the Coral Snake, from closest to furthest.
Organism 1: ATTGGCCATAC
Organism 2: ATCCGGGATAG
Organism 3: ATTCGCCATAC
Answer:
The organism closest to the coral snake is organism 3, followed by organism 1 and finally organism 2.
Explanation:
The more similar the DNA composition of the organisms, the closer and more closely related they are. With that we can say that the coral snake is closer to organism 3, since the sequence of nitrogenous bases in its DNA is more similar, in relation to other organisms. After organism 3, it is organism 1 that most resembles a coral snake. Organism 2, however, has a different DNA composition, the organism being less similar and the more distant from the coral snake.

How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer.
Answer:
Population of some organisms increases and some decreases with the increase in temperature.
Explanation:
The population of certain species such as Nassuar grouper, Spotlight parrotfish and Queen angelfish increases with the increase in temperature while some species such as yellow tail snapper, sponges and algae decreased in population with the increases in temperature. This is because some species needs high temperature so increase in temperature increases the population while some species needs low temperature so high temperature kill them and population is decreased.
Answer:
The population of some creatures increases while the population of others falls as the temperature rises. Certain species, such as Nassuar grouper, Spotlight parrotfish, and Queen angelfish, see an increase in population as the temperature rises, whereas others, such as yellow tail snapper, sponges, and algae, see a fall in population as the temperature rises. This is because some species require high temperatures, so a rise in temperature increases their number, but others require low temperatures, so an increase in temperature kills them and decreases their population.

what do you think the difference is between CER & Scientific Method? give an example.
Answer:
The main difference between the scientific method and the CER is the number of steps recommended by each one to make a valid scientific observation.
Explanation:
The scientific method consists of a set of steps that aims to establish a scientific experiment capable of explaining a scientific phenomenon hitherto unknown, or little explained. The scientific method consists of many stages, where each completes the other.
The CER method, on the other hand, has only three stages, which are claim, evidence, reasoning. This method can be established and finalized more quickly than the scientific method and is not as judicious, but it also presents efficient results to justify or explain a scientific phenomenon.

Which refers to the maintenance of a stable internal environment despite changing external conditions? differentiation self-renewal homeostasis specialization
Answer:
homeostasis
Explanation:
Living systems have the ability to maintain a stable internal environment despite changes in their external environment. The process by which they do this is called HOMEOSTASIS. Homeostasis is important for the optimal functioning of internal organs in living organisms.
An example of homeostasis is the regulation of body temperature in humans. The body uses internal mechanisms to ensure that the body temperature is kept at a stable state irrespective of the changes in environmental conditions that could affect it.
Homeostasis refers to the maintenance of a stable internal environment despite changing external conditions, option C is correct.
What is Homeostasis?A biological creature can retain internal stability while adjusting to shifting environmental conditions through a process known as homeostasis. Homeostasis is a dynamic process that can alter internal circumstances as needed to survive threats from the outside world. It is not static and unchanging.
The constant internal, external, chemical, and social conditions that biological systems sustain are known as homeostasis. In order for the organism to function at its best, a number of factors, including body temperature and fluid balance, must be maintained within predetermined ranges.

Gastrin, histamine, endorphins, serotonin, cholecystokinin, and somatostatin are hormones or paracrines that are released directly into the lamina propria. Which of the following cell types synthesize and secrete these products?
a) parietal cells
b) enteroendocrine cells
c) mucous neck cells
d) zymogenic cells
Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.

Which type of process occurred in the ecosystem that was affected by the 1988 fires in Yellowstone Park, which destroyed most of the vegetation but left the soil intact? primary succession secondary succession a climax community species extinction
The correct answer is B. Secondary succession
Explanation:
In ecosystems, secondary succession occurs as certain events such as fires cause vegetation to temporarily disappear from one area. However, as soil is not affected negatively, vegetation grows again after some time, which means there is a secondary growth of vegetation and changes in the structure of an ecological community.
This term applies to the situation in the 1988 fires in Yellowstone Park because the fire destroyed the vegetation in the zone temporarily, but as the soil was intact after years or decades the vegetation will grow again, although this might implied changes in the ecosystem.

Identify the stage of cellular respiration in which each of the following takes place,
Produces 32 ATP molecules
Creates four ATP molecules, but then gains overall only iwo
Gives off carbon dioxide
Gives off water
Produces two ATP molecules
DON
The given statements correspond to different stages of cellular respiration, which is the process by which cells generate energy from glucose and other organic molecules. The stages of cellular respiration are glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (including the electron transport chain). Let's analyze each statement and identify the corresponding stage:
1. Produces 32 ATP molecules: This statement refers to the stage of oxidative phosphorylation, specifically the electron transport chain. During this stage, electron carriers produced in earlier stages (glycolysis and the citric acid cycle) donate electrons to the electron transport chain, leading to the production of ATP through chemiosmosis. In total, oxidative phosphorylation generates a maximum of 32 ATP molecules.
2. Creates four ATP molecules, but then gains overall only two: This statement refers to the stage of glycolysis. Glycolysis is the initial step of cellular respiration and occurs in the cytoplasm. It involves the breakdown of glucose into two molecules of pyruvate and the production of ATP. In glycolysis, a net gain of two ATP molecules is produced. However, since two ATP molecules are used in the initial steps of glycolysis, the overall gain is only two ATP molecules.
3. Gives off carbon dioxide: This statement corresponds to the citric acid cycle (Krebs cycle). The citric acid cycle takes place in the mitochondrial matrix and completes the oxidation of glucose. During this cycle, acetyl CoA derived from pyruvate is further oxidized, leading to the release of carbon dioxide as a waste product.
4. Gives off water: This statement corresponds to the stage of oxidative phosphorylation. In oxidative phosphorylation, the final electron acceptor is oxygen. As electrons pass through the electron transport chain, they combine with oxygen and hydrogen ions to form water.
5. Produces two ATP molecules: This statement refers to the stage of substrate-level phosphorylation in the citric acid cycle. During the citric acid cycle, one ATP molecule is produced directly through substrate-level phosphorylation in one of the reactions. Thus, in each cycle, two ATP molecules are generated (although later stages of cellular respiration generate more ATP through oxidative phosphorylation).
In summary, the stages of cellular respiration corresponding to each statement are as follows:
1. Produces 32 ATP molecules: Oxidative phosphorylation (electron transport chain)
2. Creates four ATP molecules, but then gains overall only two: Glycolysis
3. Gives off carbon dioxide: Citric acid cycle (Krebs cycle)
4. Gives off water: Oxidative phosphorylation (electron transport chain)
5. Produces two ATP molecules: Citric acid cycle (substrate-level phosphorylation)
