Acceleration involves a change in __________.a.
time only
c.
velocity over time
b.
distance only
d.
none of the answers are correct

Answers

From the formula for acceleration, a = (v -u)/t

Where v = final velocity, u = initial velocity, t = time

(v -u) represents Change in velocity.

Acceleration is hence Change in velocity overt time. Option C.

What is the function of the prostate gland

Answers

Makes some of the liquid in semen. Also helps to regulate urine flow. Common site of male cancer.

Answer:

The prostate gland is a male reproductive organ whose main function is to secrete prostate fluid, one of the components of semen. The muscles of the prostate gland also help propel this seminal fluid into the urethra

Explanation:

If a DNA molecule was a spiral staircase, what would the steps of the staircase be?

Answers

Answer:

Nitrogenous bases

Explanation:

DNA is a nucleic acid molecule that acts as the genetic material of the organisms. The structure of DNA is made of two strands of nucleotides that are linked together and form a helical structure. The helical structure is known as the double-helical model with a ladder-like appearance.

The backbone of the ladder is composed of the sugar and phosphate groups at alternate positions whereas the staircase of the ladder are made of the different type of nitrogenous bases (A, G, T, C) joined by the hydrogen bond.

Thus, Nitrogenous bases is the correct answer.

Scientist use data from Gregor Mendel‘s studies to conclude that information about traits is passed from parents to offspring through

Answers

The correct answer is genes.

A trait refers to the feature like size or color, which is passed from the parents and is inherited by the offspring. The genes control traits and come in pairs, that is, one gene from each parent.

The transmission of hereditary traits possesses its molecular framework in the accurate DNA replication. This generates gene copies, which can be transmitted to the offspring from the parents. In plants and animals, the reproductive cells known as gametes are the mediators, which transfer genes from one generation to the next.

Answer:

According to the data from the experiments of Gregor Mendel, the information about the traits is passed from parents to offspring is through the genes.

Explanation:

In Gregor's studies, he stated that factors are inherited from parents to offsprings which are responsible for inheritance of traits lie eye color, hair color etc.
Later these factors are named as genes.
There are millions of genes which codes for different traits.
Genes are units of DNA.
There are two copies of gene for one trait in an offspring. One comes from mother and second comes from father.

The arterioles (small arteries) leading to an organ, constrict in order to decrease flow to the organ. To shut down an organ, blood flow is reduced naturally to 2.80% of its original value. By what factor did the radii of the arterioles constrict? Penguins do this when they stand on ice to reduce the blood flow to their feet.

Answers

The final radii of the arteriole is reduced by the factor of 0.409 after the constriction of the arteriole.

The flow rate is defined as the amount of fluid flow through the artery in the given time period at the cross-sectional area.

Computation for the radii of constricted arterioles

The flow rate for the artery is given by:

$Q_1=(\pi Pr^4)/(8\eta l)$

Where, P is the pressure, r is the radius, $\eta$ is the viscosity, and l is the length.

The value of flow rate is reduced to 2.80 % of its natural values. The reduced flow rate is given as:

$Q_2=Q_1\;*\;(2.80)/(100) \nQ_2=0.028Q_1$

The ratio of the flow rate is given as:

$(Q_2)/(Q_1) =(r_f^4)/(r_i^4)\n\n (0.028\;Q_1)/(Q_1) =(r_f^4)/(r_i^4)\n\n0.028\;r_f^4=r_i^4\n\nr_i=0.409r_f$

The final radii of the arteriole is reduced by the factor of 0.409 after the constriction of the arteriole.

Answer:

The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells.

Explanation:

When the vessels suffer vasoconstriction, the blood supply is decreased and in this way the heat of the body is maintained. The way this happens is because the blood can no longer reach the surface and therefore decreases outward heat radiation. The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells. There are several factors that cause vasoconstriction, internal or external. Environment is one of the external factors, and what happens to the penguins' feet is an example for it, since they are trying to preserve body heat to survive.

Sodium is an example of an alkali metal. The alkali metals are found in the leftmost column of the periodic table, known as Group 1. Use the interactive periodic table to explore the properties of the following alkali metals: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical property common to alkali metals: they react with water. How does the reactivity vary among this group of elements? Why might patterns like this be useful to scientists?

Answers

The reactivity of alkali metals increases down the group. Periodic trends help scientists to predict the reactivity of newly discovered elements.

In group 1, reactivity of elements increases down the group because as you go down the group more shells are added thereby making it easier to remove the outermost electron.

This explains the increase in chemical reactivity from Lithium to cesium.

These periodic trends are very important in predicting the chemical reactivity of newly discovered elements that are added to a group.

Answer:

The reactivity greatens the farther you go down on the periodic table. Lithium will have the weakest reaction, and cesium will have the greatest reaction. Patterns like this are useful to scientists because it shows which elements are the most reactive and which aren't. The farther down and to the left you go within the periodic table, the more reactive the elements become. The farther up and to the right you go, the less reactive they become.
