What makes Volvox unique?In the northern region, the eyespots are more developed. This helps the colony to swim towards the light. This differentiation of cells makes Volvox quite unique. It is a colony that comes really close to being a multi-celled organism.
What is a fact about Volvox?

Which sentence describes what happens to plastic that absorbs energy from
sunlight?
A. It becomes brittle.
B. It shrinks.
C. It darkens in color.
D. It becomes stronger.
Answer: A
Explanation: just took the test :)
The plastic that absorbs energy from sunlight becomes shrink. The correct option is B.
What are harmful effects of plastic?Endocrine disrupting substances (EDCs) are among them; they have been connected to a number of diseases such as infertility, obesity, diabetes, prostate cancer, and breast cancer.
In addition to these problems, chemicals have also been related to issues of neurodevelopment, growth, and reproduction.
Chlorinated plastic has the potential to leak dangerous chemicals into the soil around it. These chemicals can then seep into nearby water sources, including groundwater, and the ecosystem.
The species that consume the water may experience a variety of potentially dangerous impacts as a result.
The plastic is exposed to sunlight, which oxidises it and converts the polymers into oligomers, extremely soluble organic molecules.
Plastic breaks down into smaller molecules and absorbs UV radiation from the sun, thus how quickly it decomposes depends on how much of it is exposed to sunshine. This process is known as photodegradation in science.
Thus, the correct option is B.

is osmosis passive or active transport
Answer:
Passive Transport
Explanation:
Osmosis does not require ATP so it is a passive transport. Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of ATP
message me btw : )
Answer: Osmosis is passive transport.
Explanation: Water moves from areas where solutes are less concentrated to areas where they are more concentrated.

The producer in an energy pyramid contains about 1,000 kcal of energy. About how much of this energy is used by the producer or lost as heat to the environment? 10 kcal 90 kcal 100 kcal 900 kcal
Answer:
900 kcal
Explanation:
According to 10% law , only 10% of total energy of primary consumer is transferred to secondary consumer . The rest is lost either to the environment as heat or consumed by the primary consumer .
So out of 1000 kCals of energy 900 kCals will be lost to the environment as heat or consumed by the the producer .
Answer:
900cal

Please Help!!! Explain how the Periodic Table of elements is organized. What are the patterns? Trends?
Answer:
They are the alkali metals, alkaline earth metals, transition metals, other metals, metalloids, non-metals, halogens, noble gases and rare earth elements.
The chemical elements in the periodic table are organized from left to right and from top to bottom based on the atomic number.
How is the periodic table of elements is organized?The periodic table of elements also known as the periodic table is an organized alignment of the 118 elements known at present. The arrangement of chemical elements is done from left to right and from top to bottom on the basis of the enhancing atomic number, or the number of protons in the nucleus of an atom that usually coincides with the enhancing atomic mass.
On the periodic table, the horizontal rows are known as periods, in which each period number demonstrates the number of orbitals for the elements in that row.
Thus, the periodic table of elements is organized from left to right and from top to bottom based on the atomic number.
