………….what are alveoli
Answer:
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body. Carbon dioxide travels in the blood from the body's tissues and passes through the alveoli to be breathed out.

DNA cannot leave the nucleus because that would risk it getting damaged.
Explain which sound wave has the greatest amplitude?
A
Wave A because the compressions and rarefactions are more similar, so it has a larger amplitude.
B
Wave A because the rarefactions are more tightly packed, giving it a greater frequency
C
Wave B because the tightly packed compressions give it a longer wavelength.
D
Wave B because the compressions are more tightly packed, giving it a larger amplitude
D
Wave B because the compressions are more tightly packed, giving it a larger amplitude

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.
Answer:
Parasitism
Explanation:
Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.
A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.
What are different types of symbiotic associations?In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.
Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.
In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.
In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.
Hence, the fourth option is the correct answer, which is parasitism.

Photophores help the animals which zone of the ocean? How do they help?
Question 6 options:
coasts - tentacles to attach to rocks
frozen ocean areas - help blood from freezing
deep sea areas - attract prey with light
coral reef areas - calcification for skeletal protection
Answer:
Deep Sea Areas
Explanation:
Photophores are animals that produce light.
Photophores help the animals in deep sea areas—attract prey with light of the ocean. Therefore, the correct option is C.
What are photophores?Deep sea animals live in complete darkness where no sunlight can penetrate. In order to find food or mates, many of these animals have evolved special light-producing organs called photophores. These organs emit light, which can be used to attract prey or to communicate with other members of the same species.
The light produced by photophores can vary in color, brightness, and pattern depending on the species. Some animals use their photophores to create a dazzling display that confuses or disorients their predators, while others use them to mimic the appearance of other animals or objects in their environment. Therefore, the correct option is C.

Actually Welcome to the concept of Genetics and color.
According to the above condition, we will get the remaining results of crisscross as,
4.) YYPp ==> Yellow
5.) YyPp ==> Orange (both expressed)
6.) yyPp ==> Pink
7.) YYpp ==> Yellow
8.) Yypp ==> Yellow
9.) yypp ==> White
In this case, we have to recognize the concepts of genetics, so the phenotype for each exercise color:
YYPP=orangeYyPP=orangeyyPP=pinkYYPp=orangeYyPp=orangeyyPp=pinkYYpp=yellowYypp=yellowyypp=whiteWhat is a phenotype?Phenotype is an important concept adopted in Genetics and is usually defined as the set of observable characteristics of an organism. In this sense, the morphological and physiological characteristics of an individual are included in this set.
So from the information given in the statement we have that:
When both pigments are expressed, the flowers appear orange.When only one pigment is expressed, the flowers are either yellow or pink.When neither pigment is expressed, the flowers appear white.Phenotypes are expressed by the following colors:

Explanation:
Answer:
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

What enzyme opens up in the DNA into two single strands ?
Answer:
DNA helicase
Explanation:
The image of this question shows the replication of DNA into two identical copies. However, before this occurs, the double-stranded DNA needs to be unwound or separated so that each single strand can serve as a template for a new strand.
An enzyme called DNA helicase is responsible for the separation of the DNA molecule into single strands. After which, DNA polymerase begins to add nucleotides to each single strand of DNA.
A company called Sierra Pacific Industries is destroying forests by a destructive and non-sustainable practice called clearcutting. This is being done at an alarming rate in specific counties in California.
A.Primary Succession
B.Secondary Succession
Answer:
Secondary succession.
Explanation:
Clearcutting leaves an area barren. It is a horrible practice and is opposed by every environmental group. There are better ways of logging without destroying the plant life present there. This is secondary succession because plant life did exist in the area that clear cut and will again if the logging company or the government will replant the area.
at what point did the climate began to fluctuate more severely ? (2 points )
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..
Significado del acoplamiento entre CTE y FosOx, es de bioquimica si alguien me puede ayudar por favor
Answer:
La teoría quimiosmótica indica que la cadena de transporte de electrones (CTE) y el proceso de fosforilación oxidativa (FosOx) están acoplados por un gradiente de protones.
Explanation:
La teoría del acoplamiento quimiosmótico propuesta por Peter Dennis Mitchell permite entender cómo el ADP se fosforila a ATP en mitocondrias y cloroplastos. La energía que se libera durante la cadena del transporte de electrones es utilizada por la célula para crear un gradiente de protones a través de las membranas internas de mitocondrias y cloroplastos. Subsecuentemente, la energía potencial creada a partir de este proceso es liberada por el movimiento de protones a favor de un gradiente electroquímico. Finalmente, la energía potencial creada a partir del flujo de electrones es acoplada a la fosforilación oxidativa para sintetizar enlaces fosfato de alta energía en el ATP a partir de ADP y fosfato (Pi).

describe the process of cell division that occurs to produce daughter cells during asexual reproduction

Mutations contribute to genetic variation within species. Mutations can also be inherited, particularly if they have a positive effect. For example, the disorder sickle cell anaemia is caused by a mutation in the gene that instructs the building of a protein called hemoglobin.
