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
Answers
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?
Answers
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.
Which is the simplified version of Kepler’s third law when one of the planets being compared is Earth?(1 point)
Answers
How To Use Kepler’s Third Law
The following is an explanation to help you figure out how to use your calculator to solve problems involving Kepler’s Third Law, and three practice problems to check yourself with.
• If I give you the planet’s orbital period:
– Type in the orbital period
– Hit the x2 key on your calculator OR
– Type in “^” followed by “2” and hit the Enter key.
– Next, type in “^” followed by “0.333” and hit the Enter key, OR
– Next, hit the “2nd Function Key” (often says “SHIFT” or “2nd Func” or “INV”) – Hit the xy key and type in 3. Then hit enter.
– The number you see is the planet’s average distance from the sun, in AU.
• IfIgiveyoutheplanet’saverageorbitaldistancefromthesun:
– Type in the orbital distance.
– Hit the xy key on your calculator, type in 3, and hit “Equals” or “Enter” OR – Type in “^” followed by “3” and hit the Enter key.
– If you see a “square root” key on your calculator hit it OR
– Type in “^” followed by “0.5” and hit the Enter key.
– The number you see is the planet’s orbital period, in years.
Examples
• UsetheseexamplestodetermineifyouareusingKepler’sThird Law correctly:
– An asteroid orbits the sun at a distance of 2.7 AU. What is its orbital period?
• Using a = 2.7 AU, you should get P = 4.44 years.
– A dwarf planet discovered out beyond the orbit of Pluto is known to have an
orbital period of 619.36 years. What is its average distance from the sun? • Using P = 619.36 years, you should get a = 72.66 AU.
– Chiron is a dwarf planet that orbits the sun between Saturn and Uranus, and has an average distance from the sun of 14 AU. What is its orbital period?
• Using a = 14.0 AU, you should get P = 52.38 years.

Answers
Answer:
its B
Explanation:
i did it
The choice that is an example of the effect of agricultural techniques on the environment is sediment accumulation in a lake near a farm. The correct option is b.
What are agricultural techniques?Agricultural techniques are the methods that are done to do agriculture or farming. These techniques are affecting the soils and water and other environments.
Pesticides, fertilizers, and other harmful agricultural chemicals have the potential to contaminate fresh water, marine habitats, air, and soil. They may also linger in the environment for many years.
Numerous pesticides are suspected of interfering with both people's and wildlife's hormonal systems. Coral reefs and streams are impacted by fertilizer runoff.
Therefore, the correct option is b. sediment accumulation in a lake near a farm.

help asap!! "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
Answers
Answer:
A
Explanation:
This molecular variation in plants illustrates relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation. The correct option is A.
What is relative fitness?Absolute fitness is normalized relative fitness. It is a biological fitness measure that compares the reproductive rate of a genotype or phenotype to the maximum reproductive rate of other genotypes or phenotypes in a given population.
The contribution of an individual to the next generation's gene pool in comparison to the contributions of other individuals.
It is important to remember that natural selection acts both directly on the phenotype and indirectly on the genotype that controls that phenotype.
Because the molecular adaptations in chlorophyll pigments have been passed down to the next generation, this molecular variation in plants demonstrates relative fitness.
Thus, the correct option is A.

Answers
Answer:
Since sexual reproduction needs two individual animals for it to occur and genes from both, the offspring won’t be exactly like one or the other parent, so, on a larger scale, we will all be unique and diverse.
For further understanding, let’s think of an example. Your dad and mom are different than you are because you are created from both of their genes combined, creating a unique you. This promotes diversity for that we are all unique.

what is symbiosis?
Answers
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.
This is a tulip plant. A tulip plant. Which statement best describes the flower based on its physical characteristics? The tulip plant is classified as a dicot. The tulip plant has netted veins. The tulip plant has ring-like vascular bundles. The tulip plant is categorized as a monocot.
Answers
The tulip plant is characterized as a monocot.
Explanation:To determine if a plant is monocot it can be characterized by the leaf pattern. Parallel veins is one feature of a monocot plant, and the plant has flowers in multiples of three. On a tulip, the veins on the leaf are parallel.
Therefore, based on a tulip's physical characteristics we can conclude that it is characterized as a monocot plant.
The tulip plant being categorized as a monocot is what best describes the flower.
What is a Monocot?They are classified as flowering plants which have seeds that typically contain only one embryonic leaf, or cotyledon.
This feature is what classifies it as a monocot thereby making option D the most appropriate choice.
