every cell in our body contains Dna
Answer:
The tail of the sperm, the flagellum
Explanation:
We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.
Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.
Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.
Answer:
Temporal partitioning or niche differentiation
Explanation:
Temporal partitioning refers to the variability in the competitive abilities of different species competing for the same resources based on varying conditions of the environment.
The environmental factors could be light, temperature, moisture, etc. Each species specializes in feeding within varied condition of one or more of the factors.
<em>In this case, both species are in competition but while the first species feeds during the day, the second species feeds during the night. Here, light and temperature probably plays a huge factor.</em>
Temporal partitioning is also known as niche differentiation, segregation, separation or niche partitioning.
Answer:
The bones are homologous structures
Explanation:
Homologous structures are the structure which are found similar in appearance in different organisms.
The homologous structures in different organism shows that they shared a common ancestor or they diverged from a common ancestor during course of evolution that is these homologous structures are the result of the divergent evolution.
In the given question, the bat, dolphin and the cat shows the same structure of bone which indicates that they have evolved from a common ancestor and is true as they all belong to mammals.
Thus, the bones are homologous structures is correct.
Answer:
Internal and external respiration
Explanation:
Internal respiration occurs inside your body and is an exchange of your body's gasses with its blood and tissues. External respiration is similar, but gasses are exchanged specifically with the lungs.
A more simple response could be breathing(ventilation) which is the process or air going in and out of the lungs.
I hope this helps you!
