What do you mean by biome?A biome is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate.
A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

A tropical climate is found near the equator.
The answer is :
Hot and humid climateJane has a beaker containing a clear solution. She adds a liquid pH indicator to the clear solution and observes that the solution changes to bright blue. The clear solution in the beaker must be a(an)
Answer: a (weak) acid
Explanation: the solutions are mostly neutral but the pH shown by the indicator as a bright blue means it is slightly acidic meaning the pH is between 6 and 7.6
As the solution turns bright blue on addition of indicator, the solution in beaker must be a weak base.
What is a base?
According to the Arrhenius concept, base is defined as a substance which yields hydroxyl ions on dissociation.These ions react with the hydrogen ions of acids to produce salt in an acid-base reaction.
Bases have a pH higher than seven as they yield hydroxyl ions on dissociation.They are soapy in touch and have a bitter taste.According to the Lowry-Bronsted concept, base is defined as a substance which accepts protons .Base react violently with acids to produce salts .Aqueous solutions of bases can be used to conduct electricity .They can also be used as indicators in acid-base titrations.
They are used in the manufacture of soaps,paper, bleaching powder.Calcium hydroxide ,a base is used to clean sulfur dioxide gas while magnesium hydroxide can be used as an antacid to cure acidity.

What are some examples of comparative embryology in evolution?
Answer:
Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.

What is the most environmentally friendly form of building?
A. Concrete
B. Brick
C. Steel
D. Timber
Answer:
D) Timber
Explanation:
Concrete creates a large carbon footprint as carbon dioxide is released during its production. Steel releases air emision like CO, SOx, NOx, PM2. Whereas, brick is made out of clay the heat required for manufacture is usually gained from coal burning releasing emissions into the atmosphere. Although timber contributes to deforestation when managed sustainably has the potential to be carbon neutral/sustainable.

If carbon in the atmosphere increase will carbon on earth increase too?
Answer:
When carbon dioxide concentrations rise, air temperatures go up
When carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.
Two students fertilize a pair of pea plants. One plant is Rr, and the other is rr. The offspring produced by
these two plants all had the dominant trait. The Punnett square showed that there was a 50 percent
chance of the offspring carrying rr genes. So, the student assumes that he made an error in determining
W the genetic makeup of the plants. Do you think the student made an error, or is there another
explanation?
No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.
I hope that helps and makes sense!

No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.

ATP is produced, and carbon dioxide (CO2) is released.
ATP is consumed, and carbon dioxide (CO2) is released.
ATP is consumed, and carbon dioxide (CO2) is absorbed.
ATP is produced, and carbon dioxide (CO) is absorbed.
Answer:

A bat wing, an alligator leg, and a human arm are homologous structures.
Which fact about those structures best supports one aspect of theory of evolution?
The fact that the bone structures are similar supports the concept that birds evolved from mammals.
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
The fact that the bone structures are completely different supports the concept that those organisms shared a common ancestor.
Answer:
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
Explanation:
The similarity of the wings of bats, legs of alligators, and arms of humans in structure is an indication that animals shared a common ancestor according to the evolution theory.
Homologous organs are organs found in different organisms that are similar in structure but different in functionality.
The fact that these organs are similar to each other in morphological structure points to the fact that they might have evolved from the same ancestor according to evolutionists.
The wings of bats, legs of alligators, and arms of humans are all based on the same pentadactyl (five-digit) structure. However, a bat uses its wing to fly, alligators use their legs to crawl, while humans use their arms for a variety of purposes.
The homologous organ is one of the pieces of evidence used to support the evolution theory.

During mitosis, chromatin condenses into chromosomes, spindle fibers form from one end of the cell to the other, and centrioles organize the spindle fibers. Which stage of mitosis happens next?
Answer:
Metaphase
Explanation:
Mitosis is the cell division that involves the production of daughter cells that are genetically identical to the parent cell. Mitosis is undergone by every living cell and it includes four main stages: Prophase Metaphase, Anaphase, and Telophase.
The description in this question showcases the Prophase stage, which is the first stage of mitosis. The Prophase stage involves the condensation of Chromatin threads into Chromosomes. The mitotic spindle, which contains the microtubules that will separate sister chromatids begins to form. The next phase involves the aligning of chromosomes at the cell's equator, which occurs in the METAPHASE stage.

Metaphase
