Answer:
photosynthesis and cellular respiration allow the carbon and oxygen that organisms consume and produce to be cycled through the ecosystem. They work together so that what is made from one process is used in the other. Without them the ecosystem would run out of carbon dioxide and oxygen, and everything would die.
if perimeter of a square is 24cm find its area please give me easy formula
Answer:
4l = 24
so l=6
now
l*l =6*6
= 36 square cm
Answer:
36cm²
Explanation:
Perimeter of a square = 4x (sum of all 4 sides)
Perimeter = 24 cm (given)
[tex]\implies [/tex]4x = 24
x = 24/4 = 6 cm
Now, area of a square = (side)²
Area = (6)²
= 36 cm²

Energy cycles through ecosystems because it returns to the Sun.
A True
B False
Answer:
false
Explanation:
The statement "Energy cycles through ecosystems because it returns to the Sun" is definitely false.
What is an Ecosystem?An ecosystem may be defined as a type of place or an area where members of different species live together and interact with one another for the purpose of food, shelter, space, and mating partner.
The ultimate source of energy for the living being is delivered by the sun. But the sun never takes this energy in any form. It is true that the energy cycle in the ecosystem but does not passes to the sun. It gets cycled through living organisms like plants, animals, and microorganisms.
The plants captures the energy from sunlight through photosynthesis, herbivores take energy from plants, carnivores take energy from herbivores, and the microorganisms get energy from dead and organic matter.
Therefore, the statement "Energy cycles through ecosystems, because it returns to the Sun", is definitely false.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and body aches, typically occur two to seven days after infection by the virus. This information suggests that the reproductive cycle of the SARS virus is - lysogenic, because the virus is a coronavirus. lysogenic, because the virus is a coronavirus. lysogenic, because the virus primarily affects older people. lysogenic, because the virus primarily affects older people. lytic, because the virus causes respiratory illness. lytic, because the virus causes respiratory illness. lytic, because of the quick onset of symptoms after infection.
Answer:
lytic, because of the quick onset of symptoms after infection
Explanation:
As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.
The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.
Answer:
lytic, because of the quick onset of symptoms after infection

Polar bears live in the tundra. They obtain their energy almost exclusively from eating other animals, although they do eat some vegetation. Black bears that live in temperate forests tend to be more omnivorous, eating a wide variety of plants and animals for energy.
An adaptation is a behavior or an anatomical structure that can help an organism survive in its environment. Why are diet choices important adaptations for these animals’ survival in their biomes? Based on the images, what other adaptations do these animals display?
Answer:
In the tundra, vegetation is rare, so polar bears had to adapt to eat a heavily animal-based diet. In the temperate forest region, a wider variety of plants is available, so black bears can eat a more omnivorous diet. The bears’ colors are adaptations. The polar bear blends in with the snowy background, and the black bear blends in with the trees of the temperate background. The bears’ coloring could help them hunt for prey.

1.habitat
2.biome
3.environemnt
4.ecosystem
Answer:
The correct answer is 4.ecosystem.
Explanation:
An ecosystem is a system, that is, a set of elements that interact with each other, in which such elements are: physical environment, living beings and their interactions (predator-prey, parasite-host, competition, symbiosis, pollination, distribution of seeds , etc.) The interrelation between living beings (competition, parasitism, etc.) occurs through cycles of matter and energy flows on which the functioning of the entire ecosystem depends.

Two bodies of water that are approximately the same size depth and latitude are found to have a large difference in the number of species inhabiting them what is likely the contributing island biogeography factor resulting in a difference in the number of species found in each body of water?
Answer:
Due to the presence of suitable environment.
Explanation:
Suitable environmental conditions are responsible for the presence of large amount of species in water bodies because suitable environmental conditions provides necessary materials for the growth and survival of organisms. The marine environment that have sufficient amount of food, space, optimum temperature, pH and salt concentrations so in this environment more number of species are present due to increase in population as compared to those ecosystem having harsh environmental conditions.

why do vultures wait for there prey
Answer:
A vulture attacks weak prey. They hunt by sight, so they often "watch over" the prey until it is ready, by their standards. ... Sometimes vultures wait for a larger feeder to attack the meat first, so that the meat is perfect for eating.
Answer:
Vultures often wait for decay to set in because it gives them easy access to dead animals with tough skins

Natural selection causes changes in? A.genotypes. B.populations. C.individuals. D.phenotypes.
Answer:
populations
Explanation:
A) genotypes
Natural selection may happen because of different genotypes (for example, heterozygous individuals survive better). Natural selection does not change genotype.
Recall that genotype is the type of alleles one has.
B) populations
Natural selection is the survival of the fittest. For example, a drought. Or predators. Or limited food supply. Or overproduction. All will end up with the stronger, better-surviving types of a certain population. Natural selection does change populations.
C) individuals
Natural selection usually occurs when there are large amounts of a certain type of individual (for example, bunnies). They usually do not affect individuals.
D) phenotypes
Natural selection may happen because of different phenotypes (for example, green grasshoppers survive better than red ones). Natural selection does not change phenotype.
Recall that phenotype is the physical appearance one has.
Extra:
Phenotype vs. Genotype:
If A is dominant for brown hair and a is recessive for albino hair:
Genotype Aa has a phenotype of brown hair.
Genotype AA has the phenotype of brown hair.
Genotype aa has the phenotype of albino hair.
You can see how genotype and phenotype are like.
Natural selection causes changes in populations. The correct option is B.
What is natural selection?Natural selection is a biological mechanism that allows some organisms to survive and reproduce more successfully than others, resulting in the transfer of advantageous traits from one generation to the next.
Natural selection operates on the and phenotype genotype of the organism. It causes changes in the frequency of genes (genotype) in a population, which results in changes in the physical appearance (phenotype) of the population.
A population is a group of individuals of the same species living in the same geographical area at the same time. Natural selection affects populations, not individuals, as it occurs over several generations, and it results in changes in the allele frequencies in the population. Thus, natural selection causes changes in populations.
Therefore, the correct option is B.
