Some coral reefs grow larger in water that has the right amount of salt. What kind of characteristic is this?
A. behavioral
B. environmental
C. organic
D. individual
Answers
Answer:
organic
Explanation:
Specific levels of salinity can provide preferred cell conditions for the specific types of coral species. This is organic because it involves the genetics of the coral.
Answer: B. Environmental
Explanation: "Environmental means the protection of the natural world of land, sea, air, plants, and animals. Environmental means relating to or caused by the surroundings in which someone lives or something exists."
"Coral reef development occurs only in areas with specific environmental characteristics: a solid structure for attachment, relatively high water temperatures, clear waters low in phosphate and nitrogen nutrients, and moderate wave action to disperse waste and bring oxygen and plankton to the reef."

Answers
Answer:
when water flow through the canyon the water caused erosion
Explanation:
Answer:
By around 6 million years ago, waters rushing off the Rockies had formed the mighty Colorado River. As the plateau rose, the river cut into it, carving the canyon over time. Smaller rivers eventually cut the side canyons, mesas and buttes that are so characteristic of the canyon today.

Which kingdom would a species be classified in if it has a nucleus, cell walls and
chloroplasts, gets energy through photosynthesis, and is an autotroph?
A.Protista
B.Fungi
C.Plants
D.Animals
Answers
Answer:
C. Plants
Explanation:
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals, based on similarities or characteristics e.g eyes, number of legs, etc.,
The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; Kingdom, Domain, Phylum, Family, Order, Class, Species and Genus.
Additionally, the three (3) domain in which living organisms can be classified are: Bacteria, Eukaryote, and Archaea.
Thus, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
In the ecosystem, producers are autotrophs or self-feeders such as plants.
Hence, the kingdom in which a species would be classified in if it has a nucleus, cell walls and chloroplasts, gets energy through photosynthesis, and is an autotroph is the plant kingdom (Plantae).
Answer:
C. Plants
Explanation:
Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).

Nombra de forma ordenada el camino que recorre el CO2 desde el capilar sanguíneo que rodea el alveolo hasta salir del cuerpo.
Answers
Answer:
El aire ingresa al cuerpo a través de la boca o la nariz y se mueve rápidamente hacia la faringe o la garganta. Desde allí, pasa a través de la laringe o laringe y entra en la tráquea.
La tráquea es un tubo fuerte que contiene anillos de cartílago que evitan que se colapse.
Dentro de los pulmones, la tráquea se ramifica en un bronquio izquierdo y derecho. Estos se dividen aún más en ramas cada vez más pequeñas llamadas bronquiolos.
Los bronquiolos más pequeños terminan en diminutos sacos de aire. Estos se llaman alvéolos. Se inflan cuando una persona inhala y se desinflan cuando una persona exhala.
Durante el intercambio de gases, el oxígeno pasa de los pulmones al torrente sanguíneo. Al mismo tiempo, el dióxido de carbono pasa de la sangre a los pulmones. Esto sucede en los pulmones entre los alvéolos y una red de pequeños vasos sanguíneos llamados capilares, que se encuentran en las paredes de los alvéolos.
Aquí puede ver los glóbulos rojos que viajan a través de los capilares. Las paredes de los alvéolos comparten una membrana con los capilares. Eso es lo cerca que están.
Esto permite que el oxígeno y el dióxido de carbono se difundan o se muevan libremente entre el sistema respiratorio y el torrente sanguíneo.
Las moléculas de oxígeno se adhieren a los glóbulos rojos, que viajan de regreso al corazón. Al mismo tiempo, las moléculas de dióxido de carbono en los alvéolos salen del cuerpo la próxima vez que una persona exhala.
El intercambio de gases permite que el cuerpo reponga el oxígeno y elimine el dióxido de carbono. Hacer ambas cosas es necesario para sobrevivir.

Let's say your name is Gilligan, you've survived a shipwreck and you're stranded on a desert island. You happen to have been stranded with a medical doctor that has a limited stock of medical supplies. One of your shipmates is in desperate need of a blood transfusion but doesn't know his blood type. You do know your blood type. How could you type his blood with your knowledge and limited medical supplies?
Answers
Answer:
In order to find the blood type of the shipmate, Gilligan mixes a little blood of the shipmate with himself firstly and than with individual blood types to simplify the data by process of elimination.
Explanation:
There are a total of four types of blood groups which are as follows:
A blood grp has anti B antibodies, has A antigen B blood group has anti A antibodies, has B antigen AB blood group has no antibodies, has A and B antigen O blood group has no antigens, has anti A and anti B antibodiesIn order to find the blood type of the shipmate in the deserted needs of a blood transfusion, mixing of your blood with some of his blood is carred out:
if no clumping seen then the shipmate has same type of blood group as you or has AB blood group (AB has no antibodies). If clumping is seen then person has O blood group(has both anti A and anti B antibodies) or the other type of blood group (that is if Gilligan's blood group is type B, if clumping is seen then the other person's blood group is O or A type because he has anti B antibodies in both of them)With your partner list three biological processes involving biosynthesis break down what you think your body could carry out using the matter and energy from the beef burger

What are antibiotics and why are they useful?
Answers
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.
Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria.
Uses: Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.

HELP!!!! two questions pls :)
Answers
Answer:
1.
To back up the scientist, when a person is more fit, their breathing will return to a normal rate faster than average, as B's rate returned faster than everyone else's, they are more fit.
Another reason the scientist could be right, is when a person is very athletic and fit, their resting heart beat is lower than an average person's heart rate. As person B has the lowest at 10, this would make them more fit.
2.
If the scientist counted wrong at all while measuring breath rates, the results could be wrong.
If each person did a different form of exercise, the results could also be wrong as different forms of exercise for each person would make the expirement inconclusive. (some exercises take more from the body than others).
