Given what we know about the water cycle we can confirm that the process that happening in the biome is the process of condensation
Although the water cycle can be divided and subdivided into various processes, we can simplify it into four simple steps:
EvaporationCondensationPrecipitation CollectionThe one saw in the biome and one of the most essential parts of the cycle is condensation. It is the collection of water molecules into a single group that, when dense enough, fall back onto the earth as rainfall. In nature these take the form of clouds, meanwhile, in the biome, they appear as water on the sides of the container.

What evidence of climate change on continents supports the theory of continental drift?
signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents
Answers
Answer:
A
Explanation:
Edge2022
The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.
What is continental drift theory?The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.
This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.
Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.
Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.
This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.
This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.
Hence option B similar coal fields on different continents is correct.

why is mechanical digestion of food important?? please help I only need one reason marking brainliest btw
Answers
Answer:
it makes the food smaller
Explanation:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

What is the probability that a couple will have a type A child if the mother has Type
A blood and is heterozygous for the trait and the father has type AB blood?
Answers
Answer:
50%
Explanation:
To solve this, we'd need to use a Punnett square. Since the mother has a heterozygous genotype and has an A-blood phenotype, we know that she is AO and the father is AB.
A B
A AA AB
O AO BO
According to this, the four possible blood types, with equal probability are: AA, AB, AO, and BO. Both AA and AO genes will result in type-A blood, since A is dominant over O. Therefore, there is a 2 in 4 (or 1 in 2, or 50%) chance of the child having type-A blood.

now you’ll examine an operon that undergoes negative and positive control. the ara operon in e. coli codes for enzymes that metabolize the sugar arabinose, which e. coli can use for energy. as you can see in the diagram, the regulatory protein arac can act as both an activator and a repressor of the ara operon.
Answers
The lac operon is known to be able to undergoes negative and positive control.
The diagram based on the 4 table arrangement is filled up below (Right to left);
In the presence of arabinose: initiator, activator, yes, yes.In the absence of arabinose: initiator and operator, repressor, no, no.
If a mutation prevents arabinose from biding to AraC: initiator and operator, repressor, no, no.
If arabinose is present but a mutation and AraD enzyme renders it non-functional: initiator, activator, yes, no.
The metabolism of the sugar arabinose is known to be influenced by an operon that is said to undergo both positive control and negative control.
Transcription of the ara operon is lead by the regulatory protein AraC, which then bound to the DNA.
When arabinose is present, it binds to AraC, and both parts of the AraC dimer are then also bound to the initiator, making transcription to move foreword.
When arabinose is absent, one part of the AraC dimer is often bounded to the initiator, while the other part is bounded to the operator, thereby hindering transcription.

The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside? osmosis diffusion passive transport active transport.
Answers
Answer:
It's active transport
Explanation:
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
What do you mean by Ion uptake?Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.
Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
