Explanation:
describe how competition, predation and
symbiosis influence the population size of the organisms concerned.
Answer:
Interactions among organisms in an environment include predation, competition, and symbiosis. It's conceivable that the population sizes of species that benefit from such an association will grow. Similarly, if a contact is harmful to an organism, the population size of that creature is likely to decline.
When a predator hunts for another organism, it is called predation. The prey is the organism that is hunted. Predators will have more food if the number of prey grows. Predators will have a larger population as a result of this. More prey will be consumed when there are more predators. As a result, the prey population will shrink. As a result, a predator-prey population cycle emerges.
In a given habitat, competition occurs when two organisms or species compete for the same limited resource. Light, food, and shelter are examples of limited resources. The population size of the species receiving less of the resource is likely to shrink. Similarly, the population size of the species receiving more of the resource is expected to grow.
A symbiotic relationship is a close relationship between at least two species that. At least one species involved in a symbiotic relationship benefits. The other member(s) involved in the relationship is/are either helped, harmed, or not affected. Mutualism is a symbiotic relationship that benefits all species involved in the relationship. Therefore, the population sizes of the members involved in a mutualistic relationship are likely to increase. Commensalism is a type of symbiotic relationship in which one member benefits and the other member is neither helped nor harmed. The population size of the species that is helped within such relationship will increase. The population size of the species that aren't harmed won't alter. A parasite and its host form a third sort of symbiotic connection known as parasitism. The parasite gains from the relationship, but the host suffers as a result of it. As a result, parasite population sizes are likely to grow. Similarly, the size of the host population is likely to shrink.

To prevent the accumulation of hormones in our bodies, the hormones are constantly being metabolized and excreted. where are adrenal and gonadal steroid hormones excreted?
Hormones from the adrenal and gonadal sytems are eliminated through the urine or bile in the liver.
Unbound steroid hormones from the gonadal and adrenal glands are transformed in the liver, where they become inactive, and subsequently eliminated through the bile or urine. The lungs, cell metabolites, or feces do not contain adrenal or gonadal steroid hormones. The steroid hormones are broken down by several tissues, but mostly the liver, into physiologically inactive byproducts that are primarily excreted in the urine, although some are also removed via the bile and, finally, the feces. Analysis of urine steroids may aid in the diagnosis of endocrine disorders. The liver is the primary site of steroid metabolism. Tetrahydro derivatives are created in the first step by reducing double bonds and adding hydroxyl to the ring.

B) Malpighian tubule-insect
C) kidney-frog
D) flame bulb-snake
E) direct cellular exchange-marine invertebrate
The mechanism of "direct cellular exchange" for osmoregulation or nitrogen removal is incorrectly paired with the animal "marine invertebrate".
Direct cellular exchange, also known as diffusion/osmosis, is a mechanism commonly used by freshwater invertebrates, such as protozoa and flatworms, to regulate their internal solute concentrations.
Marine invertebrates, on the other hand, generally use other mechanisms for osmoregulation such as active transport or specialized organs like nephridia or gills.In marine invertebrates, the process of osmoregulation is critical for maintaining homeostasis in the face of changing salinity levels in their environment.
Some marine invertebrates have adapted to life in extremely salty environments, while others live in more dilute environments, and have developed various mechanisms to cope with the unique challenges posed by their habitat.
These mechanisms include specialized cells or organs that help regulate salt and water balance within the body.

Answer:
Protein digestion begins in the mouth
Fat digestion begins in the stomach
Once a protein supply reaches your stomach, hydrochloric acid and enzymes referred to as proteases spoil it down into smaller chains of amino acids. Amino acids are joined collectively through peptides, that are damaged through proteases.
Fat digestion starts offevolved withinside the stomach. Some of the byproducts of fats digestion may be immediately absorbed withinside the stomach. When the fats enters the small intestine, the gallbladder and pancreas secrete materials to in addition spoil down the fats.
What is digestion?The approaches of digestion encompass six activities: ingestion, propulsion, mechanical or bodily digestion, chemical digestion, absorption, and defecation. The first of those approaches, ingestion, refers back to the access of meals into the alimentary canal thru the mouth.

Explain why every cell that is produced from the genetically modified bacterium
will be able to produce insulin.
Answer:
Recombinant DNA is technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory. Then they remove a loop of bacterial DNA known as a plasmid and insert the human insulin gene into the plasmid. Researchers return the plasmid to the bacteria and put the “recombinant” bacteria in large fermentation tanks. There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria and purify the substance for use as a medicine for people.
Explanation:
each nephron contains a tubular structure with three parts through which the filtrate passes. the order of these structures is:
Each nephron contains a tubular structure with three parts through which the filtrate passes. The order in which the filtrate passes through the tubular structure is as follows: Glomerular capsule or Bowman’s capsule → Proximal convoluted tubule → Loop of Henle → Distal convoluted tubule → Collecting tubule.
Glomerular capsule or Bowman’s capsule: It is a double-walled structure present at the beginning of the nephron. Blood from the renal artery enters the glomerulus and filters out water, salts, and waste products.
Proximal convoluted tubule: The filtrate from the glomerulus enters the proximal convoluted tubule. This tubule is lined with epithelial cells and reabsorbs some ions, nutrients, and water back into the bloodstream.
Loop of Henle: This is a U-shaped tube that extends down from the cortex and into the medulla of the kidney. The loop of Henle plays a crucial role in maintaining a concentration gradient in the kidney. It also plays a crucial role in reabsorbing water and ions back into the bloodstream.
Distal convoluted tubule: The distal convoluted tubule is the part of the nephron that lies between the loop of Henle and the collecting duct. This part of the nephron is responsible for the reabsorption of ions and water. It is also responsible for the secretion of hydrogen ions and potassium ions.
Collecting tubule: The collecting tubule is the last part of the nephron. It is responsible for the reabsorption of water from the filtrate and the concentration of urine. The filtrate then leaves the collecting tubule and enters the renal pelvis. The urine then passes through the ureter and into the bladder.

write a 1 paragraph explanation on how the Big Bang is the start of the universe.
Answer:
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with an infinitely hot, infinitely dense singularity, then inflated — first at unimaginable speed, and then at a more measurable rate — over the next 13.8 billion years to the cosmos that we know today.
Because current instruments don't allow astronomers to literally peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
While the majority of the astronomical community accepts the theory, there are some theorists who have alternative explanations besides the Big Bang — such as eternal inflation or an oscillating universe..

While walking in a park, Mia observes grasses, shrubs, wildflowers, rocks, algae, a stream, water plants, frogs, turtles, birds, a squirrel, and a snake. What is one way Mia can organize these by level of organization?
Mia can organize the elements by level of organization as individual organisms (frogs, turtles, birds, squirrel, snake), populations (group of each species), communities (grasses, shrubs, wildflowers, rocks, algae, water plants), and ecosystem (including the stream and all the components mentioned).
One way Mia can organize these elements by level of organization is by utilizing the ecological hierarchy or levels of ecological organization.
This hierarchical framework allows for the classification of living and non-living components based on their organizational complexity and interactions.
Starting from the simplest level to the most complex, Mia can organize these elements as follows:
Individual Organisms: Mia can group the frogs, turtles, birds, squirrel, and snake as individual organisms. These are distinct living entities that interact with their environment.Populations: Within the individual organisms, Mia can identify different populations such as a population of frogs, turtles, birds, squirrels, and snakes. A population refers to a group of individuals of the same species living in the same area and potentially interacting with one another.Communities: Mia can consider the grasses, shrubs, wildflowers, rocks, algae, and water plants as components of a community. A community comprises multiple populations of different species interacting and coexisting within a given area.Ecosystem: Mia can observe the stream, along with all the living and non-living components mentioned above, as an ecosystem. An ecosystem represents a community of organisms and their physical environment, including abiotic factors such as water, rocks, and soil.By organizing these elements using the ecological hierarchy, Mia can appreciate the interconnections and interdependencies among the different levels of organization within the park's natural environment.

7. _______________ plant growth increases the length of shoots and roots, while _______________ growth results in an increased girth as layers of woody tissue are laid down.
Answer:
Primary plant growth increases the length of shoots and roots, while secondary growth results in an increased girth as layers of woody tissue are laid down.
Explanation:
Primary growth is as a result of rapid cell division in the shoot apical and root apical meristem. Primary growth leads to an increase in the length of the shoot and the root.
Secondary growth is as a result of cell division in the lateral meristems (vascular cambium and the cork cambium) thereby making the root and stem thick. Secondary growth leads to an increase in thickness or girth of the plant as layers of woody tissue are laid down.
