Answers

Answer:

- the discovery of the Pangaea Theory.

In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.

The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.

Why must the bonds of these molecules be broken before anything else happens?

Answers

Answer:

Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.

Explanation:

Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. Chemical reactions can occur spontaneously or require an outside trigger such as an input of energy. Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.

Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.

Why the bonds of molecules are broken?

Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.

Chemical reactions create and destroy the chemical bonds that hold molecules together, creating new materials as their end product. Chemical reactions can start on their own or need an outside trigger, like an energy input. Chemical reactions can be endothermic or exothermic in that breaking chemical bonds takes energy while creating new ones releases it.

Answer:

Since Callie has brown eyes, and all her children have brown eyes, we can only assume that the phenotype of brown eyes is dominand and Callie will have a dominant genotype, leaving Joseph to have a reccesive genotype (if Joseph was heterozygous for this aspect, he would have brown eyes) and the children will be heterozygous, with brown eyes as this characteristic predominates over blue eyes.

ATP can convert to ADP during ___________.

Answers

Answer:

phosphorylation

Explanation:

ATP usually releases energy by breaking down the weak phosphate cell present.  The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.

Donna has observed that her father can control the speed of their grandfather clock by adjusting the

height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when

the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes

for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to

move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.

Donna records her data.

2           21.56

3           20.33

4           19.00

5           18.02

Hypothesis: ____________

Constants: __________

Control Group:_________________

Experimental Group: ____________

Answer:

Hypothesis:

if the weight is lowered the pendulum will move faster

Dependent Variable:

Time it takes the pendulum to swing or move

Independent Variable:

the position of the weight

Constants:

same weight and the same number of swings

Control Group:

pendulum at the lowest position

Experimental Group:

different height of pendulums

Explanation:

A hypothesis is a possible explanation for the observation in a given experiment which is "if the weight is lowered the pendulum will move faster" as it states the effect of length of the pendulum on the time it takes to swing.

The dependent variable in an experiment is affected and measured to see the effect which is the time it takes the pendulum to swing or move which is measured here and affected by the independent variable that is the position of the weight.

Constants are the variable that remains constant throughout the experiment that is the same weight and the same number of swings. Control group is the group of subject or condition which minimize the effect of factors or variables except one factor to compare or ensure if the experiment works that are pendulum at the lowest position. The experiment group is the group of a subject that get treatment desired to influence the dependent variable that is the different height of pendulums.

predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein

Answers

Full Question Attached

Answer:

The substance would be less likely to enter the cell by active transport or might enter more slowly

Explanation:

The information in the question suggests substance L is moving into the cell by active transport. We can tell this because the concentration of substance L inside the cell is 120 mM. However, the substance is still entering the cell from a lower to a high concentration, against its concentration gradient. This requires energy and is therefore active transport.

If there was a large protein attached, the active transport machinery might not be able to move substance L at the same rate. The rate it enters the cell might slow down, or it might stop all together. It might need to enter via another mechanism, such as endocytosis.

5. leaf epidermis

6. stoma

7. root hair

8. ground tissue (xylem vessel)

Explanation:

functions of :

stomata aid in losing of water during transpiration

guard cells regulate the opening and closing of the stomata .this happens when the guard cells have a hypertonic environment they absorb water from the neighboring cells hence they expand and the stomata open .during the night the sugar levels in the guard cells have dropped hence they lose water to the neighbouring cells hence they shrink become flaccid and the stomata close.

xylem transports water to various parts of the plant

cuticle is a thin waxy and transparent layer.it is shiny to reduce excessive loss of water and it is transparent to allow light to penetrate through

root hairs are thin ,long and flexible.they are thin to reduce distance covered by diffusing water,they are long to allow their ability to tap water from underground,they are flexible to increase their ability to reach water sources .

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?

Answers

Answer:

Longshore current.

Explanation:

A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.

The energy released by the wave at shore produces a current which is referred to as a longshore current.
