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.

Suppose that you feel something brushing against your abdomen. The sensory information would be carried to the spinal cord over a ________ ramus. rami communicantes white ramus communicans posterior anterior gray ramus communicans
Answer:
The correct answer is - ventral ramus.
Explanation:
Ventral rami are the spinal nerves that bring the sensory information through the sensory fibers and motor fibers for the innervates the ventrolateral body surface, structures in the body wall, and the limbs, skin, such as abdomen and joints of limbs.
If someone feels the brushing sensation against his or her abdomen the sensory information must be carried by the ventral ramus.

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.

Creating a list of anxiety-triggering situations and training in relaxation are important aspects of
client-centered therapy.
dialectical behavior therapy.
systematic desensitization.
aversive conditioning.
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.

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.
