When the solution concentration on the outside of a cell is greater than the solution concentrate on the inside of the cell, what type of solution is the cell within?
Answers
Answer:
Hypotonic solution
Explanation:
The solution with lower solute concentration is referred to as hypotonic solution while the other with higher solute concentration is called as hypertonic solution.
Since the solution concentration on inside of the cell is lower than that of solution present on the outside the cell; the solution inside the cell is hypotonic.
What is point source pollution of an aquatic ecosystem
Answers
Answer: Point source pollution is water pollution that comes from a direct single source and can easily be traced. Some examples of point source pollution can be oil spills, sewage drainage pipes, unlined landfills
Point source pollution occurs when pollutants enter an aquatic ecosystem from a single identifiable location, such as sewage discharges, leading to problems like eutrophication and harm to aquatic life.
Explanation:Point source pollution of an aquatic ecosystem refers to contaminants entering the environment from a single, identifiable source. Examples include discharges from wastewater treatment plants, factories, and combined sewers. During heavy rain, combined sewer systems may overflow, leading to direct spilling of untreated sewage into water bodies.
Eutrophication is another consequence of point source pollution, wherein excessive nutrients, such as nitrates and phosphates from waste, promote overgrowth of algae and bacteria. This leads to oxygen depletion in the water, adversely affecting fish and other aquatic life. Ocean acidification is a separate issue where excess CO2 in the atmosphere causes oceans to become acidic, which can harm corals and shellfish. In addition to chemicals, physical debris can also be a point source of pollution, posing dangers to aquatic wildlife.

Some Individuals produce more offspring than others. Which term describes this observation?
Answers
The answer is A. Differential reproduction.
Answer:
The correct answer is differential reproduction
Explanation:
The different individual in a population tends to produce a different number of offspring and this difference in reproduction among them is called differential reproduction. This differential reproduction is responsible for producing more offsprings by some individuals.
Nature allows those individuals who are better suited in their environment to survive up to reproduction age and produce offspring and many of those individuals who are less adapted do not reach to reproduction age thereby produce less offspring.

which of the following choices contains a nucleus?
a. bacteria
b. eukaryotes
c. prokaryotes
Answers
Answer:
b. eukaryotes
Explanation:
Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
Eukaryotes are the group of organisms that contain a nucleus in their cells. Unlike prokaryotes (which include bacteria), eukaryotic cells are defined by the presence of a nucleus and other membrane-bound organelles.
Explanation:The organism that contains a nucleus among the given options is the eukaryotes. To explain further, living organisms can be divided into two broad categories: eukaryotes and prokaryotes. Eukaryotes are organisms whose cells contain a nucleus and other organelles enclosed within membranes. Examples of eukaryotes are fungi, plants, and animals. Meanwhile, bacteria and prokaryotes do not have a nucleus. Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures, including a nucleus.

what is brood nurse
Answers
Hope this helps
A brood nurse in biology is a member of a social insect colony responsible for the care of the young, having specific adaptations for tasks such as feeding, grooming, and protecting the larvae and pupae.
The term "brood nurse" refers to certain members of social insect colonies, such as ants, bees, and wasps, that are responsible for the care of the young, which is known as the brood. These nurse workers have specific physiological and behavioral adaptations that enable them to perform tasks such as feeding, grooming, and protecting the larvae and pupae. For instance, in honeybee colonies, nurse bees feed the larvae with a substance produced in their hypopharyngeal glands, known as royal jelly or worker jelly, depending on the larva's diet, which will determine its development into either a queen or worker bee.

c
Nitrates are converted into proteins.
d
Nitrates are reabsorbed by the animal.
Answers
Answer:
Nitrgen Cycle
Explanation:
Animal waste includes nitrogen that passes through the nitrogen cycle, these steps summarise into:
The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms.
Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb.
Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere.
OPTION B. Nitrogen excreted by animals is released back into the environment, where microorganisms convert it to ammonia and subsequently into nitrates, which plants can then use to make proteins. Thus, the excreted nitrogen rejoins the nitrogen cycle.
Explanation:When animals excrete nitrogen, it is primarily in the form of urea or uric acid. These nitrogenous wastes are then released back into the environment. Bacteria and other microorganisms in the environment can convert these into ammonia. Ammonia is then converted into other compounds, such as nitrates, which can be used by plants to make proteins. Hence, the nitrogen excreted by animals enters back into the nitrogen cycle.

Final answer:
The term 'vibrio' is used to refer to a prokaryotic cell that is comma-shaped, distinguishing it from other bacterial shapes such as coccus (spherically shaped) and bacillus (rod-shaped).
Explanation:
In the context of bacterial shapes, when referring to a prokaryotic cell that is comma-shaped, the term that is used is vibrio. Bacteria are categorized into different shapes primarily based on their cellular morphology. For instance, coccus (pl. cocci) is a term for spherical-shaped cells, while bacillus (pl. bacilli) is used for rod-shaped cells. When bacteria present a curved rod shape, it indicates a vibrio, which are rods with a single curve, as opposed to spirillum or spirochetes that have multiple curves or a spiral shape. Therefore, the type of bacteria that is comma-shaped is called vibrio.

Apoximis is when a seed will be produced that can turn into a genetically identical plant.
Explanation;
Asexual reproduction is the type of production that results to offspring or organisms that are genetically identical to the parent plant. In plants, plants can reproduce asexually through vegetative reproduction or apomixis, without fertilization of gametes.
Apomixis is where some plants can produce seeds without fertilization. This occurs when an ovule or part of the ovary gives rise to a new seed.
