Explanation:
A close, prolonged association between two or more organisms of different species, regardless of benefit to the members is symbiosis.
Hope it helps :)
Answer:
Symbiosis
Explanation:
Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction.

I know one of the answers is that the lower temperature means the reaction will happen slower, but what’s the second answer?
Answer with Explanation:
Hydrogen peroxide is considered "unstable," thus, storing it in the refrigerator provides two advantages:
1. It slows down thermal decomposition.
The rate of decomposition slows down when the temperature is lowered. It increases when the temperature rises.2. It prevents photolytic decomposition.
Photolytic decomposition happens when hydrogen peroxide is exposed to sunlight or bright light. It therefore increases the rate of reaction. Therefore, hydrogen peroxide should be stored in a cool and dark place, such as the refrigerator.What is the function of tRNA?
a bring an amino acid to the ribosome
b catalyze the assembly of amino acids into a protein
c carry genetic instructions for building a protein
Answer:
[tex]\boxed {\boxed {\sf A. \ Bring \ an \ amino \ acid \ to \ the \ ribosome}}[/tex]
Explanation:
tRNA, or transfer RNA, plays an essential role in the process of protein synthesis (creation).
After DNA is transcripted and translated, the messenger RNA is created in the nucleus and sent to the ribosome. The mRNA has codons or sets of three nucleotides. Then, the tRNA enters. The tRNA has an amino acid (the monomer of proteins) and an anticodon (three nucleotides that are complementary to the mRNA).
The codon and anticodon create base pairs, and the amino acids attach to form a protein.
Based on this information, the best answer choice is A. bring an amino acid to the ribosome

The brain and spinal cord, both part of the nervous system, direct the muscles in the arm to swing the bat.
D.
The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
What is brain?
The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath. This arrangement is reversed in the spinal cord, where the gray matter is located within and the white matter is on the outside.
Therefore, The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.

Explanation:
Don't copy this exactly please, put it in different words because I didn't do well putting it together but there you go, lol.
Hope this helps!!!
a. The question the students were trying to answer was "Which type of soil would rose bushes grow the tallest in?" Their hypothesis was that one type of soil would lead to the rose bushes growing taller than the others.
b. The independent variable in this experiment was the type of soil in which the rose bushes were planted. The dependent variable was the height of the rose bushes. They likely measured the height of the bushes at regular intervals (e.g. daily or weekly) using a ruler or tape measure.
The conditions (variables) that were controlled during the experiment were the size of the rose bushes, the size of the pots, the amount of water, the light and temperature conditions.
What is a variable?A variable is a characteristic or property that can take on different values or can be manipulated in an experiment or study. In science, variables are used to help understand the relationship between different factors or phenomena.
They can be classified as independent variables, which are manipulated by the experimenter, and dependent variables, which are observed or measured as a result of the manipulation of the independent variable. In some cases, there are also controlled variables which are kept constant in an experiment

Write the important of biology in our daily lives with respect to agriculture and industry
Answer:
Biology is an interesting subject that has been intriguing scientific minds for several centuries
Explanation:
Despite exponential developments in technology over the past few centuries, the origin of life on earth is still one of the biggest mysteries yet to be unraveled.
The basis of our very origin and existence on earth lies within the depths of the biological sciences. Biology has an endless array of species( at least as of now because there are an estimated 8.7 million species on earth out of which only 1.9 million species have been discovered, so there is a long way to go!).
Every creation which is a part of nature is so adorable and unique in its own way.
Biology exists every second - when we inhale and exhale each time, respiration is taking place within our bodies, each cell receives oxygenated blood and releases carbon dioxide and other excretory wastes.
Let aside other species, we haven't yet understood our own bodies completely!!How is it that our hearts work so tirelessly throughout our life span, how is it that we are able to interpret even minute emotions and gestures without even understanding the mechanism behind it!.How is it that each one of us is able to perceive things differently?What exactly is consciousness?..The list of questions seeking their answers is endless!
Biology helps us to sort things out and find answers to such questions.
Humans aren’t the only living things biology is concerned with. It also tells us all about plants and animals – how they live, what they’re made up of, and how they interact with mankind and each other. This enables us to make the most of our planet’s natural resources while trying to minimize the impact we have on the environment.

"Watermelon snow" in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high altitude in year-round snowfields. In both locations, UV light levels tend to be high. The reddish-pink color of these algae is due to the presence of carotenoid pigments, which absorb blue light while reflecting red light. Those pigments protect the chloroplast from ultraviolet radiation, as well as absorbing heat, which provides the algae with liquid water as the snow melts around it. This molecular variation in plants illustrates
A. relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation
B. innate variability because plants have evolved molecular differences to an environmental stimuli
C. unselective adaptation because plants have evolved molecular differences to adapt to different wavelengths of light
D. inclusive fitness because differences in chlorophyll pigments increase the proliferation of beneficial traits in the population

A 2. Which of the following are features that help scientists classify annelids into their respective classes? O presence of setae and tentacles presence of setae and parapodia presence of setae and septa presence of coelom and parapodia
Answer:
presence of setae and parapodia
Explanation:
Annelids are groups of organisms under the phylum "Annelida". They are organisms that possess the following characteristics or features: setae, parapodia, coelom, tentacles etc. However, via the possession of not of the setae and parapodia, annelids have been classified into four major classes viz: Polychaeta, Oligochaeta, Hiradinea and Archiannelida, on the basis of their setae and parapodia mainly.
- Polychaeta: possess numerous setae and parapodia
- Oligochaeta: few setae, no parapodia
- Hiradinea: No setae, no parapodia
- Archiannelida: No setae, no parapodia
Hence, the presence of setae and parapodia will enable the scientists classify annelids into their respective classes.
Answer:
presence of setae and parapodia
Explanation:
Scientists determine what class Annelids are categorized into based on whether or they have parapodia and/or setae.

Answer:
c. arising from both the brain stem and the cortex
Explanation:
The behavioral inhibition system(BIS) according to Jeffery Gray can be explained as neuropsychological system which gives the prediction of response from individual to signal of anxiety-relevant in a particular area or environment. He stressed that BIS have a relationship of sensitivity to punishment along with avoidance motivation. The The behavioral inhibition system is usually activated when individual is experiencing negative event/ stimuli, boring moments, or punishment. Then by the time the body respond to the cues of the negative stimuli involving punishment, then the (BIS) brings avoidance of the negative event. When there is activity of( BIS) then there will be heightened sensitivity to punishment as well as nonreward experience.
It should be noted that the behavioral inhibition system (BIS) is activated by danger signals arising from both the brain stem and the cortex resulting in the experience of anxiety.
Why was miasma theory replaced?
O John Snow collected data that showed that germs cause disease.
O John Snow collected data that showed there was another cause to disease.
O New technology showed that miasma cannot exist.
O New technology showed that germs cause disease.
Answer:
Miasma theory was replaced because John Snow collected data that showed that germs cause disease.
Explanation:
The theory of miasma was proposed in the past when some scientists —like doctors Thomas Sydenham and Giovanni Maria Lancisi— thought that disease was the product of emanations originated by the decomposition of organic matter. This theory was based on the fact that diseases predominated in places with poor hygienic conditions.
John Snow, an english physician, was one of the main contributors to the microbial theory of disease. In 1854, while a cholera epidemic was occurring, he collected data and organized it statistically and then concluded that the disease was caused by germs present in drinking water. This data was contrary to the miasma theory, which would eventually be displaced by the microbial theory of the disease.

If the Pacific plate is moving at a speed of 5 centimeters per year, how many kilometers will the Pacific plate travel in 1 million years?
Answer: 50 kilometers
Explanation:
From the question, we are informed that the Pacific plate is moving at a speed of 5 centimeters per year. The number of kilometers that the Pacific plate will travel in 1 million years would be calculated as:
= 5 × 1,000,000
= 5,000,000 centimeters
Since 100000 centimeters = 1 kilometer, we would convert 5,000,000 centimeters to kilometers. This will be:
= 5,000,000 / 100,000
= 50 kilometers
