1. How do disturbances (or catastrophes) affect ecological succession? Be as specific as possible. Right answers only.
tino4ka555 [31]

Answer:

There are two types of ecological succession:

Primary succession:

Primary succession occurs in areas which were previously devoid of life. There were no organisms living in this area before. For example, lands after new glaciers or volcano  eruptions. Firstly, microorganisms begin to habitat this land, followed by plants like lichens, shrubs etc. Finally, complex life evolved from these.

Secondary succession:

Secondary succession arises in areas where life existed before but was destroyed due to natural circumstances like flood, fire etc. Small grasses inhabit this land first which are taken over by trees over  period of time.

0. Summarize the effects of progesterone and estrogen
tino4ka555 [31]

Answer:

Estrogen and progesterone are both involved in preparing the endometrium for embryo implantation. Estrogen helps to ensure conception by increasing the amount of secretory glands in the uterus. Estrogen also increases blood supply to the endometrium.

Progesterone is crucial for embryo implantation and maintenance of pregnancy. Progesterone also enlarges secretory glands that produce carbohydrates, proteins and mucin that are required for embryo nourishment before implantation. Progesterone stabilizes endometrial muscles to prevent them from contracting during pregnancy.

Explanation:

  • Estrogen and progesterone are steroid hormones of the reproductive system. Estrogen helps in conception whereas progesterone maintains pregnancy.
  • Estrogen is secreted during the follicular phase of the menstrual cycle that promotes the growth and maturation of follicles in the ovary.
  • Estrogen also induces oestrous behavior in females.
  • Secreted by the corpus luteum, progesterone is also a steroid hormone, responsible for implantation of the embryo in the uterus.

The pH of a solution containing 0.1 mM H+ is _______ ( 1mM = 10-3M)
Taya2010 [7]

Answer:

The pH of a solution containing 0.1 mM H+ is 4

Explanation:

The pH of any solution is given by the following mathematical equation -

pH = -log[H_{+}]\\----------- Equation (A)

Where,

H_{+} = the concentration of hydrogen ion in the solution.

Given

H_{+}

= 0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\

Substituting the given value in equation (A) , we get -

pH = -log[10^{-4}]

= -(-4)\\= 4

Hence, The pH of a solution containing 0.1 mM H+ is 4
