Which of the following describes plant cells but not animal cells?
A. The nucleus contains the chromosomes
B. The ribosomes assist in protein synthesis
C. Plastids store starch made during photosynthesis
D. mitochondria produce energy through respiration
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.
What is Photosynthesis?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.

A shadow is caused when an object blocks sunlight. For example, when your body blocks sunlight, you may see a shadow of yourself on the ground. How do you think the shadow of an object, such as a flagpole, would change over the course of the day as the Sun appears to move across the sky?
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: Hor/mon/es among Other things
Explanation:
Aro. usal; As you become arou. sed, blood flow to your geni. tals increases, which triggers the release of fluid from the cer. vix and the Bar tholin’s glands, which provides lubr. ication during sex. ual activity. Often, the more arou. sed you’re feeling, the more va. ginal lub. rication your body will produce. Horm ones and age; Horm. ones play a big role in va. ginal wet. ness. Higher estro. gen levels lead to increased va. ginal we. tness, but as your body starts to produce less estr. ogen during meno. pause and afterwards, your body may not produce as much va. g inal fluid, making your va gina drier. Meanwhile, as you move through your men. strual cycle and ovul. ation approaches, your cer. vix produces more va. ginal fluid, which plays an important role in helping sp. erm travel to an egg during the process of fer. tilization. Infection; Sometimes you will feel more we. t than usual if you have an infection such as bacterial va. ginosis. The va. ginal fluid helps to remove bacteria from the va. ginal canal. Infections may also lead you to produce other types of va. ginal dis. charge, which will vary in appearance depending on the type of infection. But if you notice any disch. arge that’s an abnormal color or smell, you’ll want to get in touch with your physician. Medication; Horm. onal birth control can alter your va. ginal fluid production, leaving you more w.et or dry than you’re used to when not taking the medication.

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

which one of these situations is commonly caused by acid rain?
a. people being poisoned by drinking water
b. fish and birds in freshwater habitats dying off
c. people receiving acid burns on there skin
d. whales and dolphins dying off in the oceans
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.
What do you mean by Acid rain?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.

What is the difference between cytokinesis in plant and animal cells?
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."

In an enzymatic reaction: Select one: a. The enzyme leaves the reaction chemically unchanged b. The least important level of organization for an enzyme is its tertiary structure c. Increasing temperature above the optimal value slows the reaction rate
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

The uneven heating of the Earth's surface leads to the formation of large global wind systems. The surface currents of the oceans are in turn driven by these global wind systems. Thus, option B is correct.
What are global winds and global ocean currents?Large-scale surface ocean currents are propelled by global wind systems that are fuelled by solar energy. These currents transport heat from the tropics to the poles, altering the climate on a local as well as global scale.
Friction from the global winds, which both follow the same basic circulation, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.
Warm water and precipitation are transported from the equator to the poles by ocean currents, whereas cold water is returned to the tropics from the poles.
Therefore, The pattern of global ocean currents is one of the factors that drives global winds.
