How can you determine the number of bonds an atom can make
Answer:
The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.
Hello My name Is Chloe, Do you think you can help me with My Question
I need Facts on sharks.
I'm doing a report for school.
Thanks:)
Answers:
Here are some fact about sharks that i found cool
#1
Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey
#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

The process by which organisms that are better adapted to their environment survive and reproduce more successfully than less well adapted
organisms do.
A. Artificial Selection
B.Evolution
С.Natural Selection
D.Adaptation
Answer:
C
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Explanation:
Answer:

Explanation:
why are there 2 hydrogen atoms and only one oxygen
Answer:
Oxygen is an electronegative
Explanation:
Not only is it because in the chemical equation for water there is 2 hydrogen atoms and 1 oxygen atom, but they also share their electrons to fill their outermost levels and that are attracted together.

Name one adaptation that allows desert plants to survive with little water?
Answer:
stomata
Explanation:
This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata. The leaves and stems of many desert plants have a thick, waxy covering.
Consider two individuals that have the following genotypes: CCDd and Ccdd.
Predict the outcomes of a cross for these two individuals. What are the outcomes that could occur in the offspring? Select ALL that
apply.
A)
1/4 of the offspring will be CCdd.
B)
ccdd is not possible as an outcome of this cross,
All of the offspring will show the dominant trait for the allele.
D)
Only half of the offspring will show the dominant trait for the Dallele.
E)
All of the offspring will be heterozygous and will display the dominant
traits
Answer:
A,B,C,D
Explanation:
Since one parent is CC, there is no way to get cc as an outcome from this cross. However, there is also no way that all of the offspring will be CcDd, which is heterozygous for both traits. Therefore, this is the only answer choice that is incorrect.
As per observation about the two individuals that have the following genotypes: CCDd and Ccdd the cross are options: a,b,c,d.
Since one parent is CC, there may be no manner to get cc as an final results from this cross. However, there may be additionally no manner that every one of the offspring could be CcDd, that is impure breed for each traits.
What is genotype ?
Genotype is an individual's series of genes. The time period can also talk to the 2 alleles inherited for a specific gene. The genotype is expressed while the statistics encoded within side the genes' DNA is used to make protein and RNA molecules.
Thus it is clear that all the observations are correct.

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth's surface temperature rises.

Classification of organisms is defined as dividing living beings into different kingdoms based on their genetics, traits, and other features.
Why did Classification Schemes of taxonomists change?Taxonomists arrange and divide the organisms based on the DNA, traits, and features of the living organisms. The advancements in technology led the taxonomists to have more information on genetic lineage and arrange them accordingly. Introduction and discoveries of new species, their genetic make-up, and traits also contribute to the change of classification system. Molecular biology, cellular level studies, and genetics of species have contributed to the classification of organisms.

How do human lifestyles affect sustainability?
Construct an argumentative paragraph. Do you believe it's ethical or unethical to artificially select traits in plants and or animals? Provide evidenco to suoport your claims. It doesn't matter what side you chose, but I need it asap.I will give you any mark you want.
Answer:
The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.

Which feature of chytrids makes them different from the other types of fungi? the material that strengthens their cell walls the special digestive material they release their use of budding to reproduce their ability to live in dry environments
Answer:
the material that strengthens their cell walls
Explanation:
Chytrids originate from the kingdom fungi and a division known as Chytridiomycota. They contain a feature of unique characteristics by the presence of the chitin and the cellulose cell wall. The chitin made up the component of their cell wall in fungi but in Chytrids, the cellulose helps to strengthens their cell walls.
Answer:
A. the material that strengthens their cell walls
Please help!!!! Grizzly bears and polar bears are very closely related, so much so that they can reproduce to form hybrid offspring. Use your understanding of natural selection to describe how polar bears became a separate classification from the grizzly.
Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear
Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.
Polar bears become separate classification from the grizzly by the natural selection known as divergent and adaptive evolutionary change.
Polar bears and grizzly bears are considered as closed to one another so they can interbreed. They both diverged from one another due to the harsh climate of the Arctic and the ecology of the region.
The changes that took place are camouflaging and pigment-free fur-coat that helped them in order to adapt to the different climates.The genetic mutation leads to such Adaptive changes when the polar bears migrated northwards.The populations living in different climates undergo natural selection that is divergent natural selection and the adaptive evolutionary changes that result in different species.Learn more about speciation:

Answer:
Photosynthesis-
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after
