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.

Cystic fibrosis is one of the most common genetic diseases in America. It is estimated
that 1 in 23 Americans are carriers for Cystic Fibrosis. Cystic Fibrosis is a recessive trait
that follows Mendel's Law of Dominance.
Answer ALL parts of the free response below - be sure to use vocabulary and explain your
response in detail:
A. Explain what Mendel's Law of Dominance means
B. Explain how 2 parents who do NOT have Cystic Fibrosis could have a child with cystic
fibrosis.
Answer:
a.When an organism is heterogeneous for a trait, it expresses only the dominant allele
b. A child will be born with CF only if they inherit one CF gene from each parent. A person who has only one CF gene is called a CF carrier. They are healthy and don't have the disease. But they are a carrier of the disease.
Explanation:
a.In other words, the dominant trait always masks the recessive trait.
b.A parent can be a CF carrier, and pass the CF gene on to their child.
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.

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.

are the most reactive nonmetals.
16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.

Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.
Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.
Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

plants realease water into the atmosphere by which two processes?
Answer:
Evaporation and Transpiration
Explanation:
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.

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.

Archaebacteria and eubacteria are classified into different kingdoms, but at one time they were both classified in the Kingdom Monera. Which statement best describes why the classification of these organisms was changed?
A. The kingdom became too large and had to be made into two smaller kingdoms.
B. New biochemical data showed different evolutionary relationships within the kingdom
C. The archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
D. Chromosomal analyses indicated a new genetic combination had arisen within a certain organisms in the kingdom.
Answer:
I think the option C is correct
The statement best describes the classification of these organisms was changed is the archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
What are the characteristics of Archaebacteria?Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.
Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences.
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.
