Answer:
1. When two bones join together and fuse so that no visible separation occurs, it is referred to as a(n) synostosis, or bony joint.
2. Bones that join together and are held in place with threads of collagen, form a joint that is called a(n) synarthrosis.
3. The most complex joints are called synovial joints. They display varying amounts of mobility.
4. Bones joined together with cartilage between the ends of the bones, form a joint called a(n) amphiarthrosis.
Explanation:
The ossification of the connective tissue between two bones results in the fusion of them. As a result, now there is one bone instead of two. It's is called synostosis.
A synarthrosis is a joint that has very little or no movement at all. It has threads of collagen around them that keep the joint together.
A synovial joint is a diarthrosis joint. They have a wide range of mobility and are complex due to the number of components:
A fibrous joint capsule connected to the two bones. A synovial membrane. Synovial fluid to lubricate the joint.Articular cartilage on the bones' joint surfaces.An Amphiarthrosis is a joint with limited mobility. This type of joint has fibrocartilage that connects the two bones. We can find it in the pubic synthesis.

John Needham, Louis Pasteur, and other scientists all performed experiments to disprove ______.
a) spontaneous generation
b) evolution
c) Koch's postulates
d) binomial nomenclature
Answer:
A) spontaneous generation
Explanation:
Spontaneous Generation theory stated that living organisms could be spontaneously generated from non-living matter. Francesco Redi conducted an experiment similar to the one Louis Pasteur would do nearly 200 years later. The 17th-century Italian developed a spontaneous generation experiment that showed that maggots do not spontaneously emerge from decaying meat.
MARK THIS ANSWER BRAINLIEST PLEASE ❤️
The theory of spontaneous generation is an experiment that tries to prove the possibilities that living organisms can be produced from non-living origins.
This experiment was first done by Francesco Redi in 1668. However, several scientists such as John Needham, Louis Pasteur, John Tyndall amongst other scientist tried to disprove the theory of spontaneous generation.
The theory was later disproved by Louis Pasteur and John Tyndall in the mid-19th century.

Describe how the complete oxidation of 1 mole of glucose can generate 32 ATPs. You should include i) products of anaerobic glycolysis with numbers, ii) products of Krebs cycles with numbers, and iii) process of ATP synthesis by electron transport chain via NADH/FADH and H ions
Answer:
Explanation:
1.During glycolysis,four molecules of ATP are formed,and two are expended to cause the initial phosphorylation of glucose to get the process going.This gives a net gain of two molecules of ATP
For every glucose molecule that undergoes cellular respiration, the citric acid cycle is carried out twice; this is because glycolysis (the first stage of aerobic respiration) produces two pyruvate molecules per glucose molecule. During pyruvate oxidation (the second stage of aerobic respiration), each pyruvate molecule is converted into one molecule of acetyl-CoA—the input into the citric acid cycle. Therefore, for every glucose molecule, two acetyl-CoA molecules are produced. Each of the two acetyl-CoA molecules goes once through the citric acid cycle.
The citric acid cycle begins with the fusion of acetyl-CoA and oxaloacetate to form citric acid. For each acetyl-CoA molecule, the products of the citric acid cycle are two carbon dioxide molecules, three NADH molecules, one FADH2 molecule, and one GTP/ATP molecule. Therefore, for every glucose molecule (which generates two acetyl-CoA molecules), the citric acid cycle yields four carbon dioxide molecules, six NADH molecules, two FADH2 molecules, and two GTP/ATP molecules. The citric acid cycle also regenerates oxaloacetate, the molecule that starts the cycle.
While the ATP yield of the citric acid cycle is modest, the generation of coenzymes NADH and FADH2 is critical for ATP production in the final stage of cellular respiration, oxidative phosphorylation. These coenzymes act as electron carriers and donate their electrons to the electron transport chain, ultimately driving the production of most of the ATP produced by cellular respiration.

How does your model support the claim that
the Northern and Southern Hemispheres
have different seasons?
Answer:
Due to presence on opposite side of the globe.
Explanation:
My model support the claim that the Northern and Southern Hemispheres have different seasons due to present on different location on the globe. The seasons in the Northern Hemisphere are different and opposite of those in the Southern Hemisphere. Seasons occur because Earth is tilted on its axis. This tilting causes summer in one location whereas winter in other location. The Earth's tilt causes the Southern Hemisphere to lean towards the Sun during summer season of Southern Hemisphere while on the other hand, it is winter season in the Northern Hemisphere which leans away from the Sun.

Say you had the following DNA sequence: ATGCTGCGAAACTTTGGCTGA Let's say there was a mutation that removed one letter (the first C): ATGCTGCGAAACTTTGGCTGA Provide the 6 DNA codons that would be read following the mutation. Are they the same as the original 6 DNA codons that would have been read
Answer:
Codons after the mutation are not exactly the same as before mutation, because one base was deleted, changing the sequence of codons.
Codons before mutation: ATG TGC GAA ACT TTG GCT
Only the first one (ATG) might coincide with one of the codons before mutation.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the DNI or mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are a total of 64 codons. 61 codify amino acids, one of these amino acids is also the start point of protein synthesis, and the left three codons are stopping translation points.
The Sequence before mutation ATGCTGCGAAACTTTGGCTGA
Codons: ATG CTG CGA AAC TTT GGC TGA
The Sequence after mutation ATGTGCGAAACTTTGGCTGA
Codons: ATG TGC GAA ACT TTG GCT
Only the first one (ATG) might coincide with one of the codons before mutation.

Select the correct statement Question 65 options: 1) GPP is the energy spent staying alive 2) GPP is the energy used in cellular respiration 3) GPP is part of NPP 4) NPP is the energy used in growth and reproduction
Answer:
1) GPP is the energy spent staying alive
Explanation:
Gross primary productivity is the energy that is spent by the organism to staying alive because energy is required by the organism for doing activities that is necessary for the survival. Gross primary productivity refers as the rate at which solar energy is captured in sugar molecules during the process of photosynthesis. Producers such as plants use some of this energy for metabolism and cellular respiration as well as some for growth and building tissues.

Secondary is the type of succession that occurs when all of the usable soil has been destroyed in an ecosystem.
What is a succession?Succession is the process of change and development that occurs in an ecosystem over time. It refers to the gradual replacement of one community of plants and animals with another, as each community modifies the physical and biological environment in which it lives. There are two main types of succession: primary succession and secondary succession.
Primary succession occurs in an ecosystem that has no soil or vegetation, such as on newly formed volcanic islands or in areas where glaciers have retreated. During primary succession, the ecosystem must develop from scratch, with the creation of new soil and the establishment of new plant and animal communities. This process can take a significant amount of time.
Secondary succession occurs when all of the usable soil has been destroyed in an ecosystem. This type of succession can occur after a natural disaster, such as a fire or a flood, or after human activity, such as logging or farming. During secondary succession, the ecosystem must rebuild itself from scratch, with new soil being created and new plant and animal communities establishing themselves. This process can also take a significant amount of time, depending on the severity of the disturbance and the conditions of the ecosystem.

4. molecular
In a starch molecule, the energy is stored in the bonds between atoms, and the building blocks of this molecule are simple sugars.
Starch is a carbohydrate and a polysaccharide, this means this molecule is composed of dozens of glucose molecules that have formed a chain and it is used by organisms, especially plants to store energy.
In other words, starch is the result of glucose molecules forming a chain, and glucose is considered a simple sugar. Therefore, starch is made up of simple sugars.
On the other hand, the energy in starch can be found in the bonds between atoms. This implies once the bonds between atoms break energy is released, and this energy is used by organisms for multiple activities.
