Answer:
The inside of Neptune is very cold, which is about -214 degrees. Hence, no microorganisms could live there. Overall, the environment of Neptune sounds very unfriendly to life as we know it on earth.
Answer:
Based on their body <u>structure</u><u>,</u> flatworms and rotifers were not thought to be closely related. However, <u>bilateral symmetry and body texture</u><u> </u>showed that they are a <u>soft-bodied</u> group.
Explanation:
- Flatworm belongs to phylum Platyhelminthes and Rotifera belongs to phylum Rotifera.
- Their body structure may be different but both of them have a bilaterally symmetrical body.
- Both are aquatic animals.
- Flatworm is made up of ectoderm endoderm and mesoderm and has circular and longitudinal muscles. Rotifera is made up of skeletal and visceral muscles. So, they are soft-bodied animals.
<h2>e) option is correct </h2>
Explanation:
- Cap Z is a capping protein which controls the access to the free barbed ends of actin filaments and is therefore a major factor affecting actin filament elongation
- Capping proteins have a high affinity for barbed ends and their micromolar concentration in the cytoplasm ensures that most barbed ends are capped
- Depletion of capping protein promotes increased filament assembly away from the leading edge in migrating cells
- Cap Z helps favor actin assembly by preventing the loss of actin subunits to the barbed end and also prevent annealing of severed or de-branched filaments and they block both the association and dissociation of subunits at the barbed end
Answer:
Volume is the amount of space occupied by a sample of matter. The volume of a regular object can be calculated by multiplying its length by its width by its height. Since each of those is a linear measurement, we say that units of volume are derived from units of length.
Explanation:
The correct answer is A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.
Explanation
The filament of a flower is the sterile part of the stamen (male organ of the flower) that is located just below the anther. Its function is structural to hold the sling so that it is accessible to insects. The filament is usually cylindrical and fine. Therefore, the correct answer is A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.
