Answer:

d. tunicate larvae possess the synapomorphies of adult chordates and thus reveal close evolutionary relationships with chordates.

Explanation:

In evolutionary biology, a synapomorphy is a shared, derived character/trait which is present in an ancestor and its descendants. Synapomorphies are useful markers to establish phylogenetic relationships between sets of taxa. Tunicates (subphylum Tunicata) are sessile marine invertebrates that are considered chordates (phylum Chordata) because the larval stage has characters/traits that are similar to other chordates. Larval tunicates have a nerve cord, a notochord, tail and gill slits (conserved in adults).

Explain how fossils can give information about past environmental conditions. Give at least two examples. Answer using complete
d1i1m1o1n [39]

Answer:

The type of fossil can show what the terrain was like.

Explanation:

Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees,  in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.

Hope this helps!

A developing bean plant has more specialisation among its cell than the seeds from which it sprouted. Thus, the correct option is D.

<h3>What is germination?</h3>

Water is taken by the embryo during seed germination, resulting in the rehydration and expansion of the cells.

The rate of respiration increases shortly after the start of water uptake, or imbibition, and different metabolic activities that had been halted or greatly decreased during dormancy resume.

The seed is the capsule that contains the next plant. The process by which the newborn plant emerges from the seed husk is known as germination. When the seedling's true sets of adult leaves emerge, leaf growth begins (as opposed to the immature initial leaf structures).

Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. Slugs prefer to eat
kap26 [50]

Answer:

The correct answer is option C.

Explanation:

The slugs prefer pink flowers over the white ones. Thus, if the slugs are withdrawn from the population, the pink flowers are no more consumed and their number enhances. In a similar manner, the bees like to pollinate more pink flowers in comparison to the white ones.  

Thus, again, the pink flowers are getting pollinated in huge concentrations. Thus, the fruits and seeds are set and they produce another generation of pink flowers. Ultimately, there would be more pink flowers in the region in comparison to the white ones as the slugs that used to consume them, are also withdrawn.  

Earlier, both the numbers of pink and white flowers would remain steady as even though only some of the bees were pollinating white flowers, they were not getting consumed by the slugs. This had maintained a balance between the number of pink and white flowers. Thus, the number of pink flowers would increase with time if the slugs are removed.
