Answer:

The correct answer is - B. Lichens.

Explanation:

Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.

Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.

What would be the independent variable in the following hypothesis?
Tamiku [17]
The independent variable in the hypothesis of an observed increased in sea turtle sickness once an increase in red tide can be seen would be the increase of red tide. 

The reason for this is that red tide increases or decreases will happen independently of the amount of sea turtle sickness - therefore increasing sea turtle sickness will be dependent on the first variable. (independent one).

.A researcher alters the DNA-binding domain of a glucocorticoid receptor to that of an estrogen receptor. How would the cells re
gizmo_the_mogwai [7]

Answer:

d) They would bind glucocorticoids, and initiate estrogen-dependent synthesis

Explanation:

Both Glucocorticoids and estrogens Hormones have important but distinct physiologic functions. These two hormones belongs to the two classes of steroid hormones. Both of these hormones binds to their specific receptors.

DNA binding domain is the domain that after activation by external factors such as hormones express the specific proteins by binding to specific region of the DNA.

As DNA binding domain of a glucocorticoid receptor is altered with DNA binding domain of estrogen receptor so it means binding site of the glucocorticoid hormone for glucocorticoid receptor remains the same and binds to glucocorticoids but on binding it activates the estrogen DNA binding domain which further binds to specific region in the DNA which initiates estrogen dependent synthesis.

10. Which of the following statements about the leading strand is true?
Yakvenalex [24]

The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.

The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.

The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.

RNA primers are short RNA sequences used for the initiation of the synthesis of DNA (DNA replication) both in the leading DNA strand and the lagging DNA strand.
