Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched

Answers

Answer 1

The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.

The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.

When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.

When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling

Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

If a plant with chlorosis is unable to perform photosynthesis, what products (include
BOTH) are not being made?

Answers

Answer:

Glucose and oxygen

Explanation:

Photosynthesis is the process by which the cells of green plants synthesize their own food in the presence of sunlight. Although photosynthesis consists of various steps, it generally combines carbon dioxide (CO2) and water (H2O) to produce glucose (sugar) and oxygen gas (O2). The equation is as follows:

6CO2 (g) + 6H20 (l) → C6H12O6 (aq) + 6O2(g)

In a plant that possess chlorosis (a condition characterized by yellowing of leaves due to lack of chlorophyll), photosynthesis will not occur. This ultimately means that the photosynthetic products such as GLUCOSE AND OXYGEN WILL NOT BE MADE.

Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.

Answers

Answer:

Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.

interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.

Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.

What do you think happens to the number and the branches of nerve cells as babies mature

Answers

As a child grows, the number of neurons remains relatively stable, but each cell grows, becoming bigger and heavier. The proliferation of dendrites accounts for some of this growth. The dendrites branch out, forming “dendrite trees” that can receive signals from many other neurons when babies get mature.
