Nataliya [291]

Answer:

31. Seatbelts lock in place to make sure you don't go flying into the windshield.

32. Friction causes the soccer ball to slow down. If we were to kick a soccer ball in space, where there is no friction, it would keep on rolling until it eventually hits something or goes out of sight.

33. Heavier loads will make the vehicle move off of the table. The heavier the weight, the quicker the  vehicle will roll. Loads that are something very similar or lighter than the vehicle won't make the vehicle move by any means.

34. Gravity is the power pulling the piano toward the Earth.

Friction would happen with an unpleasant surface, making it a lot harder to push the piano up the ramp.

35. Wagon C

Wagon C has the least boxes and minimal measure of mass, making it simplest to move.

36. I would move the crates so every cart has a similar measure of boxes, making them equivalent in mass. This would make them all take a similar measure of power to move them.

Explanation: I have the answer key

Predict phenotypes associated with nondisjunction of sex chromosomes.
Mnenie [13.5K]

Answer: The new daughter cells will have an abnormal amount of genetic material. That is called aneuploidy and it is the presence of an abnormal number of chromosomes. Different clinical conditions are the result of this nondisjunction.

Explanation:

Normal cells are diploids, that means they have two copies of each gene, one of each chromosome. So normal cells have two homologous chromosomes, one from each parent.

During anaphase of cell division, each pair of chromosomes is separated  by the mitotic spindle. The separated chromosomes are then pulled by the spindle to opposite poles of the cell, and eventually will end up in the new daughter cells.

Nondisjunction is the failure of homologous chromosomes to separate properly during cell division, so it is the miss segregation of them. The new daughter cells will have an abnormal amount of genetic material. <u>Different clinical conditions are the result of this nondisjunction.</u>

Sex chromosomes participates in sex determination of an individual. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY) So nondisjunction of sex chromosomes could be:

  • XX: one cell with no chromosome and the other cell with two X chromosomes.
  • XY: one cell with no chromosomes and the other cell with XY chromosomes.

According to which gametes are fused during fertilization, different phenotypes can be given. For example, if a gamete with one chromosome fuses with another gamete with two chromosomes, the result will be an individual with three chromosomes (it could be XXY, or XXX) called trisomy.

Triple X syndrome is characterized by an extra X chromosome in females. Those affected are often taller than average, but most females have a normal sexual development. Klinefelter syndrome is known XXY individuals, and it causes infertility in males, breast growth, less body hair and weaker muscles.

And if a gamete with no chromosome fuses also with another gamete with no chromosome, the result is a nullisomy. But due to the lack of genetic material, the nullisomic gametes are rendered unviable for fertilization.

And if a gamete with no chromosome fuses with another gamete with one chromosome (normal) the result is a monosomy, the presence of only one chromosome from a pair. The result can be an individual who is X or Y. People with Turner syndrome have one X chromosome and it is the only monosomy that is seen in humans because other cases monosomy are lethal.

Any of those examples is called aneuploidy and it is the presence of an abnormal number of chromosomes.

Which statement explains how convection currents affect the movement of plates? Gravity pulls one edge of a plate down into the
ArbitrLikvidat [17]

Convection currents direct the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle.

In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.

So, I would say the answer is:

As convection currents drift across the oceans,

they bring the pieces of Earth's crust with them as the supercontinent breaks apart.

Glad I could help, hv a good day :)

Explain the role of the cork cambium in woody plants.
kiruha [24]

Answer:

The cork cambium is a natural insulator that protects woody plants from an hostile environment.

Explanation:

The cork Cambium is a tissue that belongs to the epidermis, it is responsible for the secundary growth in the plant and replaces the epidermis in roots and stems. The cork cambium also protects the plant from overhydration, it is waterproof and has really selective ways to let the water into the plant (apoplastic and symplastic pathway).

There is some special plants in the coast of the tropical area called mangrooves, these plants has really specialized cork cambium that controls not only the water levels but also the salt levels into the plant.

The cork cambium is really important because protects and regulates the plant and its environment.
