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 .

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.

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.

It is said that “sexual reproduction promotes diversity of characters in the offspring.” Justify.
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.

L-tryptophan is an essential amino acid. What does this mean?
Answer:
Helps the body make proteins and certain brain-signaling chemicals.
Explanation:
Your body changes L-tryptophan into a brain chemical called serotonin. Serotonin helps control your mood and sleep.
Answer:
Tryptophan is an amino acid needed for normal growth in infants and for the production and maintenance of the body's proteins, muscles, enzymes, and neurotransmitters. It is an essential amino acid. This means your body cannot produce it, so you must get it from your diet.

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
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.

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.

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.

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.

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.
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.
