Humans and apes have five fingers they can use to grasp objects. Do you think these are analogous or homologous structures

1 answer:

6 0

Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.

Answer:

The correct answer will be option-thick bundles of fibers that allow communication between the brain’s hemispheres.

Explanation:

Cerebral commissures are the thick fiber tract composed of white matter which connects the same cortical areas of the left and right hemispheres of the brain.

Commissural fibers include many types of fibers in which corpus callosum fibers are one of the types of fibers which act as the main Cerebral commissures.

Since these fibers connect the two hemispheres, therefore, they help in the communication between two hemispheres.

During DNA replication, an open section of DNA, in which a DNA polymerase can replicate DNA, is called a replication fork. 2. Ok

Fiesta28 [93]

The question has been answered itself but the answer will contain the detail explanation.

Answer:

1. The replication fork formation during DNA replication is important for the continuity and the addition of the further base pair on the template. The DNA initiation process starts by the formation of replication fork.

2. The okazaki fragments are the short DNA fragments that are formed on the lagging strand. These fragments are later joined by the enzyme DNA ligase.

3. Leading strand is the continuous strand that formed during the DNA replication. The direction of the leading strand is 5' to 3' .

4. DNA polymerase is the main replicating enzyme during the DNA replication process. Different types of DNA polymerase with multiple subunits are present in prokaryotes and eukaryotes.

5. The new DNA that are formed from the parental strand and complementary with each other are called daughter DNA.

Does human intervention affect small-scale ecosystems differently than large-scale ecosystems?

sdas [7]

Answer: No

According to BBC, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.

According to National Geographic, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
