The reproductive structures used by cycads are called?a. flowers.
b. sporangia.
c. sori.
d. cones.

Answers

D. Cones
Cycads are basically composed of woody plants which have roots, a stem, leaves and reproductive structures called Cones. These cones differ from each other depending on the plant whether it is female or male. These cones vary from shape, size, color, etc. based on the sex of the plant.

Which of the following accurately describes acids and bases in regard to ionization? A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.
B. Weak acids dissociate to a great degree.
C. Weak bases dissociate only to a slight degree to produce free hydrogen ions.
D. When an acid and a base are mixed together in the proper proportions, two hydroxyl ions will unite.

Answers

The correct answer is A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.

The strength of the acid or base depends upon its degree of ionization. Since different acids and different bases dissociate or ionize to different extent in water so their degree of ionization is also different. Strong acids and strong bases ionize in water completely while the weaker acids or bases ionize partially. Ionization of the weak acids in water are in equilibrium. The degree of ionization is the ratio of the number of ionized molecules to the number of molecules which are dissolved in water. In case of acids the ionized molecules are hydrogen ions and in case of bases hydroxyl ions.

The right answer for the question that is being asked and shown above is that: "A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear." This accurately describes acids and bases in regard to ionization

What distinguishes surface and body seismic waves?

Answers

Answer: Seismic waves are the wave form of energy that travels through the earth's layer and they are produced as a result of earthquake, magma movement, volcanic eruptions, land slides and large man-made explosions.

There are two types of seismic waves. body waves and surface waves. Body waves travels through the interiors of the earth.

Surface waves travels only through the interface between earth and the atmosphere.

Body waves travel through the inner part of the earth, whereas surface waves travel through the interface of earth.

Further Explanation:

When the distortion of Earth's Crust occurs, the alternate sides of the crust of the earth experience shear stress and continues till the internal rigidity surpasses. Along the rapture calls the fault line and the sudden shaking releases mass-energy that separates the plates into two splits. The energy released during the process is referred to as Seismic Wave.

Reid’s theory is supported by the seismic theory that explains that the elastic rebound energy is preserved in-between the faults of the rocks, which is accountable for the incidence of the earthquake. The energy stored is released partly in the form of heat and partly as seismic waves. Seismic waves are considered waves that went through the Earth and are usually caused by earthquakes, volcanoes, or explosions.

These waves can be divided into two main categories:

• Body waves: These waves went through the inner part of the earth.

• Surface waves: These waves propagate at the interface or in-between to distinguishable media such as amid atmosphere and earth.

Juan’s family has a history of sickle cell disease. His father died of sickle cell disease complications when Juan was six years old. He remembers his father being in great pain. Juan marries Gina. Gina’s maternal grandmother and paternal grandfather had sickle cell disease, but neither of her parents has the disease. Juan does not want to have children because he is convinced they will have sickle cell disease. Gina is not so sure. They have come to you for advice about having whether or not to have children. Based on your calculations of the probability of their child getting sickle cell disease, what is your advice? Show your calculations and explain your reasoning for your response. It may be helpful for you to draw pedigrees and possible Punnett squares for both Juan and Gina’s families

Answers

Sickle cell disease is a hereditary disease. This means that someone can get sickle cell disease if they receive the sickle genes from BOTH parents. If someone receives a sickle gene from only one parent, then this person does not have sickle cell disease, but instead has the sickle cell trait. This means that they can still pass the trait on to their offspring. Because Juan's father had sickle cell disease and Juan does not, he carries the sickle trait. Since Gina's maternal grandmother had sickle cell disease, Gina's mother had a 50 percent chance of carrying the trait. Since Gina's father doesn't have the trait, Gina thus has a 25 percent chance of carrying the trait. If Gina has a 25 percent chance of carrying the trait and Juan has a 100 percent chance, then together they have a 125/200 chance of both passing the trait on to their children. 125/200 = .625, so they would have a 62.5 percent chance of passing on this trait to their children. Although this percentage does not mean their children would definitely have sickle cell disease, I would advise Juan and Gina to weigh their options, since 62.5 is more than 50 percent.
