the warm waters of the ocean fuel space hurricanes.
electrons and protons combining together to form a massive tornado like feature in the sky.
the planet Pluto, who is still mad about being kicked out of our solar system.
Space hurricanes are caused by streams of plasma unleashed from the sun in what's known as the solar wind.
What is Space hurricane?
This is a phenomenon in which charged electrons and plasma make up a storm instead of rain and wind.
The plasma is usually unleashed from the Sun which is why option A was chosen as the most appropriate choice.

Genetic recombination would be most closely associated with which process in disease-causing microorganisms?
A.binary fission in fungi
B.sexual reproduction in fungi
C.spore formation in bacteria
D.viral replication in host cells
Genetic recombination is most closely associated with: Choice D: Viral replication in host cells
Definition:
Genetic recombination (otherwise termed genetic reshuffling) is simply the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
In retroviruses, recombination actually occurs at the point during replication when the retrovirus genome is in a DNA form and takes place by the same break-rejoin technique as in cells and DNA viruses.
Recombination can occur both between two related retroviruses and between the retrovirus DNA and the host DNA.

How can the energy stored in the photosynthetic organism be used?
☁️ Answer ☁️
1: "Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules."
2: "The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement. "

If Pluto had not been demoted to a dwarf planet, what category of planet would it fall under? Explain your answer.
Answer:
The planet pluto originally was considered as a real planet until its demotion as a dwarf planet.
The reason it was demoted was because it was soon realized to not meet the three criteria of the International Astronomical Union used to define a full size planet.
So if pluto was not categorized as a dwarf planet than it would of just fallen under as a planet.
Explanation:
Not mine answer but it from purple6kabi

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet.

A protein may fold incorrectly if_________ brings the wrong amino acid to the ribosome to assemble the protein.
If tRNA does not bring back the appropriate amino acids, the protein may fold incorrectly. so, the blank is tRNA.
What is tRNA?The type of RNA that helps in the synthesis of proteins from mRNA, called as tRNA. tRNA acts as an adapter molecule during the translation process, and as an adapter, it connects amino acids to nucleic acids. It carries the amino acids that are added to the peptide chain and decodes the same codons in the mRNA molecule.
The structure of tRNA can be separated into primary, secondary and tertiary structures. The structure tRNA has four arms (the acceptor, D, anti-codon and -arms), three loops (D, anti-codon and -loop) and a variable region.
It binds amino acids to specific codons present in the mRNA, by acting as an adapter. Therefore, If tRNA bring wrong amino acid to ribosome for assembly of protein, protein may fold incorrectly.

Tell me something interesting about protozoa (at least 5 facts)
make it simple
Answer:
an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Hello there!!
I love protozoa so this should be fun.
1. Protozoans are unicellular beings that live in wet environments.
2. Protozoans have 2 prevalent ways of feeding:
a) the most common is utilized by heterotrophs like amoeba. An amoeba extends its elastic body until it completely surrounds the victim. Then the amoeba simply has to digest its food.
b) The second most common is through cilia. Paramecia use this method. The hair-like cilia in its mouth catch hold of food and push the meal into the paramecium's digestive tract.
3) The only protozoan to have its own family is Euglena.
4) Euglena has its own family because it has chloroplasts (meaning it can undergo photosynthesis) but it can also feed like a heterotroph. Because Euglena exhibits both plant and protozoan qualities, it has its own category.
5) Rotifers move by two spinning wheels of cilia. This type of propulsion makes the rotifer a speedy little protozoan.

What is the difference between Hinduism and Nirvana
Answer:
The most ancient texts of Hinduism such as the Vedas and early Upanishads don't mention the soteriological term Nirvana. This term is found in texts such as the Bhagavad Gita and the Nirvana Upanishad, likely composed in the post-Buddha era. The concept of Nirvana is described differently in Buddhist and Hindu literature. Hinduism has the concept of Atman – the soul, self asserted to exist in every living being, while Buddhism asserts through its anatman doctrine that there is no Atman in any being. Nirvana in Buddhism is "stilling mind, cessation of desires, and action" unto emptiness, states Jeaneane Fowler, while nirvana in post-Buddhist Hindu texts is also "stilling mind but not inaction" and "not emptiness", rather it is the knowledge of true Self (Atman) and the acceptance of its universality and unity with metaphysical Brahman.

can u plz explain the role of the digestive, endocrine, and excretory systems in maintaining homeostasis.
Answer:
Following are the roles of the digestive, excretory and endocrine systems in terms of homeostasis:
The endocrine system regulates the secretion of various hormones and homeostatic mechanisms in response to signals of the hypothalamus and pituitary glands.The excretory system maintains homeostasis by purifying the blood and getting rid of toxic waste from the blood.The digestive system is mainly involved in the transfer and regulation of nutrients from food.Explanation:
Role of Endocrine System:
The endocrine system mediates all the chemical signaling in the body.
Hormones are chemical messengers that the endocrine system uses to maintain chemical homeostasis.
Endocrine system manages glucoregulation by controlling the secretion of the hormones glucagon and insulin by the pancreas. Low and high blood sugar levels are sensed by the brain which then signals the endocrine system to release glucagon and insulin respectively.
The endocrine system is also indirectly involved in thermoregulation. A low core temperature signal received by the hypothalamus initiates the release of TSH by the pituitary gland and then that of T3, T4 thyroid hormones that stimulate shivering thermogenesis in the skeletal muscles.
Role of Digestive System:
The digestive system regulates the amount of nutrients absorbed in the body.
Although the absorption of nutrients in food is not exactly according to bodily needs, the absorption of dietary iron and calcium is strictly regulated by the digestive system.
Role of Excretory System:
The excretory system carries out osmoregulation which is the maintenance and regulation of water and salt levels in the blood.
The excretory system regulates the excretion of toxic waste from the blood.
Excess water, salts, urea and bilirubin (produced as a result of RBC break down) are some of the excretions.
