Answer:

The position of the sun affects the change in the direction and size of the shadow of the object. When sunlight is blocked by and object a shadow forms, as the earth moves on its axis daily it looks like the sun rises in the east and sets on the west.

When the sun is low in the sky the more light is blocked by an object which means the shadow will be longer and shadow will always point far from the direction of the sun.

In the morning sun is in the east so the shadow will be towards the west in the morning, shadows are long and point northwest and at noon, shadows are short and point north late afternoon shadows are long and towards the northeast.

Answer:C. Plastids store starch made during photosynthesis

The statement that describes plant cells but not animal cells is the plastids that store starch made during photosynthesis. Thus, the correct option for this question is C.

Photosynthesis may be defined as the process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

Animal cells do not perform photosynthesis so they do not have plastids. Plastid is a type of cell organelle which is specific to only plant cells that significantly store starch that is synthesized during the process of photosynthesis.

Animal cells have cell organelles like mitochondria, endoplasmic reticulum, etc. while chloroplast and plastids are specific to plant cells.

Therefore, the statement that describes plant cells but not animal cells is the plastids that store starch made during photosynthesis. Thus, the correct option for this question is C.

Answer:

The primary difference between cytokinesis in plant and animal cells is that cellular reproduction is done sexually (meiosis) in animal cells, while cellular reproduction is done asexually (mitosis) in plant cells.

To better elaborate, Sciencing.com, states, "In plant cells, cytokinesis simply consists of the cell plate forming at the equator of the old cell that will soon be two. The cell plate–the future cell wall that will separate the two cells--divides the cytoplasm in half. . . . Cytokinesis in animal cells is more complex than in plant cells. A contractile ring, underneath the original cell's membrane, begins to form and contracts, which creates the cleavage furrow. The furrow grows deeper between the two cells until they pinch off and separate from one another, resulting in two separate daughter cells."

Prairies are unique ecosystems that are dominited by grass and other plants.

Answer:

the total amount of matter

Explanation:

In a closed system, the total amount of matter remains the same as it is transferred between organisms and the physical environment, even though its location or form changes.

When one organism consumes another, this matter can change form, but it does not disappear. Eventually, the matter is broken down by decomposers and deposited in the ecosystem's soil, where it can be used by plants. From there, it is able to begin the cycle all over again.

There are four phases in the cell cycle. Thus, the four phases are the G1 phase, S phase, G2 phase, and M phase.

Chromosomes and other cell components duplicate to create two copies of themselves over the course of the cell cycle. Following this, the cell divides into two daughter cells, distributing one copy of the duplicated material to each.

G1, S, G2, and M are the four distinct stages of the cell cycle. DNA replication takes place during the S or synthesis phase, and the cell divides during the M or mitotic phase. The other two phases, G1 and G2, sometimes known as the "gap phases," are equally significant but less striking. Further M phase is divided into prophase, metaphase, anaphase, and telophase.

Thus, the G1 phase, S phase, G2 phase, and M phase are the four main phases in a cell cycle.

The statement that best describes the benefit of studying biology is the ability to intelligently debate issues such as cloning.

Explanation:

Biology encompasses the study of all known forms of life, including their anatomy, organization, functioning and interactions.

One of the advantages of the knowledge acquired through biology is to be able to participate in works and discussions involving subjects related to living beings, including cloning.

The other options are not correct because:

A situation that is commonly caused by acid rain is the dying off of fish and birds in freshwater habitats. Thus, the correct option for this question is B.

Acid rain may be defined as a type of precipitation that correspondingly include acidic components, like sulfuric acid, nitric acid, etc. that fall to the ground from the atmosphere in wet or dry forms like rain, fog, hail, etc.

The pH of acid rain is generally low compared to normal water. So, it causes numerous impacts on the earth's surface. But the most consequential influence of acid rain is the destruction of fish and birds in freshwater habitats.

It generally lowers the pH of the freshwater ecosystem and makes it unfavorable for many organisms like producers, small fishes, birds, etc. They cannot adapt themselves to such lower pH and have to dye off.

Therefore, the correct option for this question is B.

A network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem is known as Food web.

A food web is the natural interconnection of the different food chains and a graphical representation of what-eats-what in an ecological community in the nature. Another name used for the food web is the consumer-resource system.

Organisms which are present in the food webs are grouped into different categories are called as trophic levels. These levels are divided into producers, consumers, and decomposers.

Food web are the interactions which integrates the transfer of matter and energy between the living organisms which eat, and are being eaten by other organisms, capturing thus essential information about the species interactions, materials flow, community structure, and the ecosystem functioning.

Answer:

c. Increasing temperature above the optimal value slows the reaction rate

Explanation:

Enzyme activity is  affected by factors, such as temperature, pH, and concentration.

The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.

Thus, the correct option is "C"

c. Increasing temperature above the optimal value slows the reaction rate
