Vedmedyk [2.9K]

Answer:

hemoglobin will bind more oxygen when the partial pressure is low than when the partial pressure is high.

Explanation:

Binding of hemoglobin to oxygen is regulated by several factors. However, the partial pressure of oxygen is the most important factor that determines how much oxygen will bind to hemoglobin. When the partial pressure of O2 is high, hemoglobin binds with large amounts of O2. On the other hand, when the partial pressure of O2 is low, hemoglobin is only partially saturated.

Therefore, the greater the partial pressure of oxygen, the more O2 will bind to hemoglobin until saturation is reached. This is why a lot of O2 binds to hemoglobin in pulmonary capillaries where the partial pressure of oxygen is high.

What causes an ecosystem to move from a primary successional stage towards a relatively-stable mature ecosystem?
Gnoma [55]

Answer:

The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".

Explanation:

In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

Match the following.
valkas [14]

Answer:

1 . The stage on the first meiotic division when the homologous chromosomes move to opposite poles but the sister chromatids remain together

: b. Anaphase I

2 . The stage in the second meiotic division where sister chromatids migrate to opposite poles

: c. Anaphase II

3 . A structure on the chromosome that holds a pair of chromatids together during replication

: f. centromere

4 . A double-stranded chromosome following replication attached by a centromere

: d. chromatid

5 . A condition where non-sister chromatid of homologous chromosomes exchange genes

: e. crossing over

6 . The stage in the first meiotic division where the homologous chromosomes line up as a pair

: a. Metaphase I

7 . The stage in the second meiotic division where the chromatid pair lines up at the equator of the cell: g. Metaphase II

Explanation:

DNA replication occurs during the S phase of the interphase of the cell cycle. The replicated DNA molecules are accommodated in two sister chromatids of a chromosome that are held together by a centromere.  

During prophase I, the chromatids of a homologous chromosome pair exchange a genetic segment. This process is called crossing over. It generates recombinant chromatids with new combinations of genes.

Metaphase I of meiosis I includes the alignment of homologous pairs of chromosomes at the cell's equator. This is followed by separation and movement of homologous chromosomes to the opposite poles of the cell during anaphase I.  

Metaphase II of meiosis II includes the alignment of individual chromosomes, each with two sister chromatids, on the cell's equator. During anaphase II, splitting centromere separates the sister chromatids which then move to the opposite poles of the cell.

List and explain the three parts of the Declaration of Independence
emmasim [6.3K]
The Declaration contained 3 sections: a general statement of natural rights theory and the purpose of government; a list of grievances against the British King; and the declaration of independence from England.
