Complex carbohydrates not broken down by digestive processes are _______

Question 3

love history [14]

Answer:

3. Hot spots , 4. S shaped mid oceanic ridge, pacific ocean.

Explanation:

The Hawaiian islands are located on the hotspots that are formed by the collision of two strong plates and the presence of volcanoes and high magnitude earthquakes as the pacific plate is continuously moving on the western side as its subducting under the North American plate and hence shrinking in size.

The s-shaped Atlantic ocean has mid atlantic ridge and as this ocean spreads the lava is up welding across the ocean floor and hence the opening of the atlantic plate is seen.

The video compares the key similarities and differences between mitosis and meiosis. Determine which events occur in mitosis, me

notka56 [123]

Answer:

Mitosis:

A single division occurs, separating sister chromatids

End result is two diploid cells that are genetically identical to each other and the parent cell

Meiosis:

The first division separates homologous pairs; the second division separates sister chromatids

Homologous chromosomes pair up and form chiasmata

Homologous pairs of chromosomes line up on the metaphase plate

Daughter cells contain recombinant chromosomes

End result is four haploid cells that are genetically different from each other and the parent cell

Mitosis and Meiosis:

Chromosomes duplicate during interphase

Process starts with a diploid cell

Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell

Explanation:

Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.

A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.

Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis. During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.

Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.

Arrange the sequence of events for the overall mitochondrial respiratory assembly in the correct order.

kotykmax [81]

Answer:

Option D, 4,2,1, 3

Explanation:

The mitochondrial respiratory chain (MRC) comprises of four membrane bound complexes and it involves the following steps

a) RC complexes (RCC) I and II reduces the RC’s equivalent where RCCI i.e receives electron from the NADH.

b) These electrons are then transferred to the flavin mononucleotide factor and then passed on to the Fe-S embedded cluster .

c) These electron reduces the coenzyme Q to ubiquinol

d) With in the inner mitochondrial membrane (IMM), protons are trans located from IMM to the intermembrane space (IMS)

e) RC complex II then transfer electron from succinate to the cofactor FAD

f) From FAD proton are transferred to the FeS cluster and on the other hand electron move from QH2 to the RC complex III

g) This RC complex III give its electrons to the cytochrome and they are further passes on to the RC complex IV

h) With four redox centers, the terminal RC complex translocate protein by using energy produced in electron transfer thereby converting oxygen into water.

Hence, the correct option is D

olchik [2.2K]

From what I believe, 50%. The chromosome from the father can either be X or Y, so it’s a chance to carry it in the X gene if the child is a girl. If its a boy, then it has no chance of carrying the gene. Hope this helps
