what is symbiosis?
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.
Ethan vacationed with his family in Florida and had the opportunity to observe sea turtles hatching. After breaking out of their shells, the young hatchlings headed toward the ocean as quickly as possible. What kind of behavior were the hatchlings exhibiting
Answer:
In the case of the sea turtles hatching witnessed by Ethan and his family, the behavior exhibited is called an instinctive behavior.
The sea turtle knows that, the place which they are in (Inside the shells) are not where they are supposed to be in but rather should be inside a water body. Because of these, their instinct kicks in to free themselves from the shell and head towards the ocean.

Which of the following groups represent organs that can be found in plants?
roots, stems, leaves, flowers
roots, leaves, bark, stems
roots, leaves, cells, stems
roots, stems, chloroplasts, flowers
Stems, roots, leaves, and bark. The three fundamental organs of vascular plants are the roots, stems, and leaves; nevertheless, these organs frequently have undergone specialization for a variety of purposes and do not appear to be "typical."
What are organs of plants?An organ is a collection of tissues that perform the same function and are located in the same place. Roots are plant organs. They firmly anchor plants and have root hair cells on their surface that absorb water and nutrients from the soil. Additional plant organs include flowers, leaves, and stems. Among these, the stems that support reproductive organs, such as angiosperm flowers and conifer cones, are the most visible. A group of tissues that collaborate to perform a specific function as a structurally sound functional unit. Plants' major organs are the leaf, root, stem, and reproductive organs. The leaf's primary function is to produce food for the plant via photosynthesis.To learn more about organs of plants refer to:

A type of bacteria reproduces through binary fission every hour. What happens to the number of bacteria each hour?A type of bacteria reproduces through binary fission every hour. What happens to the number of bacteria each hour?
Since binary fission is the direct division of bacteria from which two cells result that means every hour the number of bacteria will double.
Answer:
the number of bacteria will double and 32
Explanation:
because in 1 hour its 2 and in 2 hours its 4 so it doubled or you can check in 3 hours it was 8 and in 4 hours it was 16 so it doubled. And when you double 16 do find the amount in 5 hours it is 32.

How can mutualism cause an evolutionary arms race?
Answer:
In evolutionary biology, an evolutionary arms race is a struggle between competing sets of co-evolving genes, traits, or species, that develop adaptations and counter-adaptations against each other, resembling an arms race. These are often described as examples of positive feedback.

In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs.
Which statement about the event represented in the diagram is valid?
Answer:
"The genes for all organisms are composed of the same building blocks"
Explanation:
The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.
The given event in the diagram is known as crossing over which takes place during the process of meiosis.
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic material
this results in the recombination of the genetic material and creates a new genetic combination.
Thus, genetic variations occur which can be beneficial to the offspring.
Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.
only expressed when the dominant allele is not present
the answer you are looking for is recessive gene
A genetic mutation causes a squirrel to be born with much darker fur than its parents.
How will this mutation most likely affect the squirrel population?
Because the trait was caused by a mutation, it will not be passed on to any offspring, resulting in the disappearance of the trait.
Because the trait was caused by a mutation, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is unfavorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
Answer: If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
The mutation most likely affects the squirrel population if the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. The correct option is D.
What is mutation?A mutation is a change or modification in the DNA or gene sequence of the organism. The modification is done due to mutagens. These mutagens delete or insert or replace the bases and cause differences.
Here, due to mutation, the color of the squirrel changed to black, so if the gene of black color will be transferred to future generations, it can be dominant or recessive.
Thus, the correct option is D, If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.

The number of valence electrons an element has changes often, so we cannot use the periodic table to predict the number of valence electrons an element
has
True
False
Answer:
False
Explanation:
The number of valence electrons on an element is also the same or else it would be a different element.
The statement that the periodic table cannot be used to predict the number of valence electrons is: FALSE
The number of valence electrons an element has will always remain the same for the element to remain the same element, elese the element will changes with a change in valence electrons. therefore we can use the periodic table to predict the number of valence electrons that an element has.
A valence electron is an electron that is located in the outermost shell of an atom or element. It is negative and it is used for the formation of bonds between atoms or elements.
Hence we can conclude that The statement that the periodic table cannot be used to predict the number of valence electrons is: FALSE .

The 1st Law of Thermodynamics states that energy is neither created nor destroyed only transfer to forms. Why is a food chain an excellent example of this Thermodynamic law?
Answer:
Food chain is an excellent example of the first law of thermodynamics.
Explanation:
First law of thermodynamics states that energy of the universe is constant. It is always found in the universe in some form or the other. It cannot be destroyed or totally used up and we cannot also create energy out of anything in this world. Energy transforms from one form to another form.
Food chain is considered to be an excellent example of 1st law of thermodynamics. Every living organisms in the world posses energy. And all living organisms consumed each other or eat each other for their survival and consumes these energy to survive. So the energy possessed in one organisms or animal is transferred to the other organism that is higher in the food chain when they eats the lower organisms or animal in the food chain.
Thus energy transfers form one form to another.
