Then the scientists studied how this mineral behaved. For example, they looked into how dense bridgmanite becomes and how much it squashes. The team then compared these traits to what is known about the blobs themselves.

This research showed that in the lab, bridgmanite behaves much as does the mineral seen in the mantle’s blobs. The scientists also showed that bridgmanite isn’t rigid enough to hold together as an intact blob without help from something else. “This challenges the assumption that these piles are self-supporting,” Jackson says. “It’s evidence that there is something else propping them up.”

What will be the long-term consequences if the hunts of baby deer continue? If they stop?

grin007 [14]

Answer:

If people continue to kill baby deer then the population will start to decrease and if they stop killing them then the deer population will increase. If the deer population increase than that won't be a good thing for the environment because they will then be everywhere. Plus where there is prey there is predator so the predators of the deer will also increase in population.

Ability to roll the tongue is caused by a dominant allele. A woman is a "roller," but one of her parents is not. Reference: Ref

matrenka [14]

Answer:

1/2.

Explanation:

The autosomal dominant trait may en defined as the trait that can express itself even in the heterozygous condition and in the homozygous dominant condition as well.

Let the B allele is responisble for the roll tongue and b is recessive allele. The woman can roll the tongue and she must have the genotype Bb because her one parents is normal. The woman married with a man with non roller ( bb). The Bb × bb cross results in the following progeny Dd, Dd ( roller), dd and dd ( non roller). The probability of the child being a roller is 1/2,

Thus, the answer is 1/2.

Most animals with backbones, vertebrates, have a similar body plan: skull, ribs, two pairs of limbs, tail. What does this sugges

daser333 [38]

The correct answer is E. Vertebrates are all related to a common ancestor

Explanation:

According to biology and evolution, organisms from different species but that share similarities in morphology (body structures) as well as in genetics often have a phylogenetic relationship which means they descend from the same organism or share a common ancestor. This applies to multiple taxonomical levels including classes such as mammals or birds as it has been proved each of this derived from a common ancestor. Therefore, the similarity in the body structure (morphology) in all mammals suggest vertebrates are related to a common ancestor and as they evolved from this, they share similarities not only in terms of morphology but also in genetics.
