A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.

Explanation:
In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930’s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation.
A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring.
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area.
D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.
Answer:
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
Explanation:
Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.

Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?
Hi, rachellelunaa!!
I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.
I really hope this answers your question!!
The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.
What are the cranial bones?Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).
The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.
Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.
Therefore, preventing damage to skull and brain, we are born with separate cranial bones.

Write 5-6 sentences that explains roles of Heredity and probability.
Answer:
Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.

A student created a table to compare animal adaptations. Based on the table, which
animal has a behavioral adaptation, and how does it give the animal an advantage?
Animal Adaptation
Duck Webbed feet
Squirrel Collects and stores food
The duck, because the behavioral adaptation allows it to catch prey.
The duck, because the behavioral adaptation helps it survive the environment.
The squirrel, because the behavioral adaptation provides food during winter.
The squirrel, because the behavioral adaptation to have more offspring.
Answer:
B
Explanation:
Ducks have the webbed feet so, they could swim in the water so they don't drown. That is animal adaptation to the environment.
Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.
What is behavioral adaptation?The behavioral adaptation of collecting and storing food is an important survival strategy for many animals, including squirrels. During times of abundance, such as the fall months, squirrels will collect and store food, such as nuts and seeds, in order to have a food source during times of scarcity, such as the winter months. This allows the squirrel to survive and avoid starvation during times when food is less readily available.
Hence, Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.
2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.
3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.
Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Which statement best distinguishes aerobic from anaerobic respiration?
A. Only aerobic respiration involves fermentation.
B. Only anaerobic respiration occurs in the mitochondria.
C. Only aerobic respiration requires oxygen.
D. Only anaerobic respiration produces carbon dioxide.
Answer:
C. Aerobic respiration
Explanation:
Aerobic respiration occurs when oxygen is present
Anaerobic respiration occurs in the absence of oxygen. Anaerobic respiration is usually associated with fermentation process (eg Alchohol production)
The main difference between aerobic and anaerobic respiration is that aerobic respiration needs oxygen to occur, while anaerobic respiration does not. Option C. Only aerobic respiration requires oxygen.
What is cellular respiration?
Aerobic and anaerobic respiration occurrence depends on the presence or absence of oxygen. Option C. Only aerobic respiration requires oxygen.
Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
What is Aerobic Respiration?This type of respiration occurs in the presence of free oxygen. It involves a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
Aerobic Respiration occurs in mitochondria, and takes place in two steps or stages: Krebs cycle and electron transporter chain.
Glycolysis and Krebs cycle produce electrons. These electrons then travel along the electron transporter chain while releasing energy, and ATP is produced.
What is Anaerobic Respiration?This is the type of respiration that occurs in the absence of free oxygen.
It is also a series of reactions by which the cell produces 2 ATP molecules by using pyruvate (product of glycolysis).
Anaerobic respiration can occur in two ways: lactic fermentation and alcoholic fermentation.
Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.
Options:
A). Only aerobic respiration involves fermentation. FALSE.
Anaerobic respiration involves fermentation.
B). Only anaerobic respiration occurs in the mitochondria. FALSE.
Aerobic respiration occcurs in mitochondria and anaerobic respiration occurs in the cytoplasm.
C). Only aerobic respiration requires oxygen. TRUE
Anaerobic respiration does not need oxygen.
D). Only anaerobic respiration produces carbon dioxide. FALSE
Alcoholic fermentation produces CO₂ too.
The correct option is C. Only aerobic respiration requires oxygen.
