Answer:
e.The plant life cycle alternates between two distinct, multicellular reproductive stages—one diploid and one haploid—that give rise to each other.
Explanation:
Alternation of generation refers to alternation of multicellular diploid and haploid forms in an organism's life cycle. It is found in some plants and algae. In plants it is as follows:
- Two haploid gametes fuse to form a diploid zygote.
- Diploid zygote develops into diploid sporophyte by mitosis and then produces haploid spores by meiosis.
- Haploid spore germinates into a haploid gametophyte by mitosis and it produces haploid gametes.
- The gametes fuse and the cycle repeats.
Thus, alternation can be observed between diploid sporophyte and haploid gametophyte.
Answer:
not entirely sure what your asking but have some notes
Explanation:
Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as "body waves". Surface waves arrive last and are the least interesting to seismic tomographers because they don't penetrate deep inside the Earth, therfore provide little information about inacessible terrain.
Below, some of the major differences between P and S waves are highlighted.
P Waves:-
known as LONGITUDINAL waves
or compressional waves
1st to arrive at seismic stations
shakes the ground in the direction they propagates
Travels through the Earth's core
Your answer would be B. The reason is because the ears of any species of fox are used to keep cool, depending on the size of the fox's ears. In this case, the arctic fox is trying to stay warm, to the ears must be smaller in order to conserve heat. Hope this helps!
Life has the following major characteristics that define it;
- It responds to stimuli
- It reproduces
- It exhibits growth and development
- It has some order – has levels of organization
- They regulate their internal environment through homeostasis
These characteristics distinguish the living thing from non-living things.
