When glucose, a 6-carbon sugar, is broken down during glycolysis, what product forms?
Answer:
pyruvate
Explanation:
In glycolysis, the 6-carbon sugar, which is glucose, is broken down into two molecules of a 3-carbon molecule called pyruvate.
During glycolysis, glucose is broken down into ; Pyruvate molecules and energy
Glycolysis is a cytoplasmic process during which glucose is broken down into two 3 carbon compounds ( pyruvate ) and energy is generated from t glucose in the process.
The breakdown of glucose during glycolysis is as represented below
Glucose + 2 NAD⁺ + 2ADP + 2Pi ----> 2 Pyruvate + 2 NADH + 2 H⁺ + 2ATP + 2 H₂O
Hence we can conclude that During glycolysis glucose is broken down into ; Pyruvate and energy.

Modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve
from them.
Aepycamelus don't share any evolutionar relationship with modern camels.
Aepycamelus are modern camels' closest extinct relatives.
Aepycamelus are modern camels' closest living descendants.
Answer:
A. Modern camels share an evolutionary relationship with Aepycamelus, but they didn’t directly evolve from them.
Explanation:
The phylogeny chart shows that modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve from them
What is a phylogeny chart?A phylogeny chart is a chart that shows the relatedness of organisms by charting structural relationships in order to determine their evolutionary origins.
From the phylogeny chart , modern camels, Camelus share an evolutionary relationship with Aepycamelus as they both originate From a common ancestor, Protylopus.
However, modern camels do not directly originate from Aepycamelus.
Therefore, it can be concluded that modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve from them.

The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

How does resolution of a microscope help you to observe different structures of the cell.
Answer:
The resolution of a microscope or lens is the smallest distance by which two points can be separated and still be distinguished as separate objects.
Explanation: The smaller this value, the higher the resolving power of the microscope and the better the clarity and detail of the image. ♀️
Conduct online research to learn more about competition between two species not mentioned in this lesson. Make sure to include information about their niches, common resources, and other competitors.
Answer:
In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.
All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.

As opposed to protists, all plants are non mobile. So, the correct option is (C).
What are Protists?A protist is defined as a eukaryotic organism that is not an animal, plant or fungus that shares a common ancestor, the exclusion of other eukaryotes means that protists do not form a natural group or clade.
Protists are primarily unicellular microscopic organisms that may share some morphological and physiological characteristics with animals or plants or both.
Protozoa, algae, and slime molds are some examples of members of the kingdom Protista, a highly heterogeneous collection of microbial eukaryotes where many protists show at least some similarity to each other.

Explanation:
it is systematic desensitization.
Creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.
Systematic desensitization is a type of therapy based on the combination of relaxation methods with gradual exposure to the fear (phobia).The objective of the exposure to the fear is that the patient feels progressively less anxious about his/her phobia.In consequence, systematic desensitization increases the feeling of self-control and gradually reduces fear.In conclusion, creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

how bones attach to each other and to muscles and how this aids movement
Answer:
Tendons connect the bones.
Explanation:
The muscles are connected to bones through tendons, and this way the contraction of the muscle helps the movement of the bones through them.
The muscles work in pairs and in this way they move. While one muscle is contracting, the other one relaxes.
The muscles work in a form of contraction-relaxing. The flexor contracts to bend a limb at a joint.
