Answer:
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

4. What best describes the role of mutations in evolution?
a. Mutations are not necessary for evolution because they are not herita
b. Mutations are useful for evolution to occur because they promote ger
uniformity within a population.
c. Mutations are essential for evolution to occur because they produce
variations within a population.
d. Mutations are essential for evolution to occur because they are respo
environmental changes.
Answer: option C.
Mutations are essential for evolution to occur because they produce variations within a population.
Explanation:
This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.
Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.

Photosynthesis converts ______________________ and ___________________ into food-energy molecule ______________________ and gives off ____________
if the answer is outrageously incorrect you will be reported
Answer:
Photosynthesis converts Light and chemical energy in to food-energy molecule sugar and gives off Oxygen
Explanation:
6CO2 + 6H2O → C6H12O6 + 6O2
Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.
Carbon dioxide, water and light are all needed for photosynthesis to take place.
Photosynthesis happens in the leaves of a plant.
(I'm not sure about the sugar part )How is antibiotic resistance related to natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Many freshwater plants have adapted to low carbon and light levels by adapting what feature?
Group of answer choices
Carnivorous plants
No need for carbon dioxide
Camouflage
Floating leaves
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water. They are therefore a common component of wetlands.

They also perform sexual reproduction in which two nuclei fuses together to
form a zygote for fertilization to take place and produce new offspring.

Chemical weathering occurs by which of the following:
heat
oxidation
hydrolysis
dissolution
water
wind
Solution, carbonation, hydration, oxidation, and reduction are significant chemical weathering reactions, hence options B and C are correct.
What is chemical weathering?Chemical weathering is the term used to explain how chemicals in rainfall alter the minerals in a rock. Rainwater becomes somewhat acidic as a result of the air's carbon dioxide being dissolved in it.
Weathering can result from an interaction between the minerals in the rock and precipitation.
Oxidation, hydrolysis, and carbonation are processes that take place during chemical weathering.
Therefore, hydrolysis is a reaction with water, carbonation is a reaction with CO₂ to generate a carbonate, and oxidation is a reaction with oxygen to form an oxide, hence options B and C are correct.

how does dog and flea interact each other ?
Answer:
A dog attaches to the dog's fur and sucks on its blood
Humans lived with domesticated dogs over thousands of years which resulted in many breeds of dogs. Humans bred some dogs to have thick
coats to keep the dogs warm in cold climates while other dogs have thin coats that live in warm climates.
Which evidence supports the claim that dogs inherit these characteristics?
O
A. During mitosis, mutations occurred and the offspring's DNA stored this information
B. As dogs digested food, mutations occurred which changed the dog's physical appearance.
O C. Since dogs lived closely in contact with humans, the dog's genetic information remained the same.
D. During meiosis, new combinations of genetic information occurred, and the offspring's genes expressed this information.
Answer:
Did humans tame woolly mammoths or other megafauna?
Considering that some people are gifted with handling animals (e.g. horse whisperers), could paleoindians or other Pleistocene peoples have gained the confidence of woolly mammoths or mastodons to use them as transportation and other tasks, the way that Asian elephants are used today?
Fewer resources would be necessary for a human to travel long distances by riding on the back of a woolly mammoth or paleocamel, as the megafauna could graze and get energy. People may also have traveled by boat during late Pleistocene times (the kelp highway along PNW).
How could we test such a hypothesis? Cave art showing a rider on the back of one of the megafauna? A bridle and/or bit? A talisman worn by a camel is known to have been crafted from a meteorite(1), and so talismans or decorations might have adorned the hypothesized woolly steed. Metal was not a known technology during stone tool usage, as far as we know, though.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.
Answer:
Yes, it is possible.
Explanation:
In this case, I'm guessing you mean breeding.
If that's the case, they will form hybrids.
Between two different species, inter specific hybrids will be formed.
Between two different genus, intergeneric hybrids will be formed.
There's even rare cases of breeding between two families.
So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.
So to answer your question, it is possible.
Green seed color (G) is dominant over yellow seed color (g). If two heterozygous parents are crossed, what are the resulting phenotypes expressed as a percent?
A) 50% green, 50% yellow
B) 75% green, 25% yellow
C) 50% GG, 50% gg
D) 25% GG, 50% Gg, 25% gg
E) none of the above
Answer:
B) 75% green, 25% yellow
Explanation:
There are three genotypes made from crossing two heterozygous parents (Gg);
GG
Gg
gg
Crossing two heterozygous parents (Gg) results in 50% Gg, 25% GG and 25% gg. Since green (G) is dominant over yellow (g), there would be a total of 75% green and 25% yellow.
