12. What is the function of the vacuole? *
(1 Point)
A. sac that stores water, nutrients and waste products
B. sac filled with digestive chemicals
C. jelly-like substance within the plasma membrane
D. stack of membranes that package materials
The vacuoles are the structures found inside the cells that store water, nutrients as well as waste products. So the correct option is option A.
The vacuole plays a vital role in many cells. Mature cells of all land plants, most fungi, and algae (with the exception of prokaryotes) contain vacuoles. On the other hand, animal cells and immature plant cells (as well as some highly immature plant cells (stone cells) contain no vacuoles.
These vacuoles store the essential nutrients and water that a cell needs to survive. They also contain the waste of the cell and protect it from contamination.

As a naturalist, you are responsible for training volunteers in the identification of the types of amphibians. The volunteers will use this information to correctly describe the animals to school groups that will visit your nature center. The training documentation for the volunteers lists important characteristics of the different groups of amphibians, but you notice that one of the items on the list is incorrect. Indicate which description is not correct.
A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
C. Some adult salamanders retain larval characteristics such as external gills.
D. Most caecilians can be found burrowing in the soil of tropical forests.
Answer:
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
Explanation:
Amphibians are vertebrates which can live both on land and in water. they are cold-blooded and therefore, depend on warmth from sunlight to become warm and active. Their young live fully in water respire using gills. The adults have moist skins through which they respire and therefore, live in moist places or near water to keep their bodies from drying out. Many adult amphibians also have poison-producing glands in their skin to ward off predators. Poisonous amphibians usually display a warning coloration. . The species in this group include frogs, toads, salamanders, caecilians and newts.
Considering the above descriptions:
A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.
True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
False: Some frogs such as poison frogs as well as some salamanders such as the California newt and the red eft which a brightly colored terrestrial juvenile form of the eastern newt is highly poisonous. advertise their distasteful nature by bright coloration.
C. Some adult salamanders retain larval characteristics such as external gills.
True: Some adult salamanders retain larval characteristics such as external gills. e.g. species such as the mudpuppy (Necturus maculosus) retain their gills throughout their lives.
D. Most caecilians can be found burrowing in the soil of tropical forests.
True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.

Can someone please do a summary on how wind works? 7-9 sentences please I will mark brainliest!
Answer:
Wind is the movement of air. It forms when air moves from areas of high-pressure to areas of low pressure. These pressure differences are caused by temperature differences on Earth's surface. The movement is a result of different places on Earth receiving different amounts of energy from the sun. Two types of winds are global and local. Global wind systems determine weather patterns for the entire planet. Local winds are sea and land breezes that occur due to uneven absorption of solar energy.

what property is the mineral in this image demonstrating?
a. magnetism
b. fluorescence
c. luster
d. streak
help me asap. pls.
When a particular wavelength of light, such as ultraviolet (UV) light, electron beams, or x-rays, are focused on a mineral, fluorescence takes place, hence option B is correct.
What is the property of minerals?Calcite, fluorite, and sodalite are among the more popular fluorescent minerals, however there are many more as well. When exposed to UV light, many gemstones, including diamonds, rubies, emeralds, amber, and opal, will glow.
This light stimulates the mineral's electrons, forcing them to momentarily move to a higher orbit.
Naturally, mine wastes and tailing heaps provide excellent locations for any mineral, including fluorescents.
Therefore, nearly everywhere that has a good assortment of white light minerals also has fluorescent minerals, hence option B is correct.

Which of the following data could best support the claim that species B arose from a speciation event in Lake I?
Answer: B
Explanation:
DNA analysis shows fewer differences between species A and species B in Lake 1 than species B and the populations in Lake 2
Speciation is defined as the mechanism through which new species or organisms are created.
What is Speciation?Speciation is an evolutionary mechanism in which the population of certain organisms evolves and becomes distinct species. It is the phyletic evolution within a lineage or lineage. In the given image, the speciation of organisms A and B shows that the difference in the genetic sequence of species and Species B in Lake I were somewhat related. Species B showed many differences to the organisms of Lake II.
Thus, species A and species B in Lake I may have arisen due to speciation.

What are the different types of leaves that plants have?
Answer:
There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant. The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets.
Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.
Answer:
The correct answer would be -
RNA - AUG GGG CCU UAC UAA
Amino acid -methionine-glycine-proline-tyrosine -stop codon
Explanation:
In the process of protein synthesis, the first process is known as transcription which involves the transcribing the mRNA strand from the DNA strand in a complementary manner. In this manner, Adenine transcribes into uracil and cytosine transcribe into guanine similarly thymine into adenine and guanine into cytosine.
Then, DNA strand - T-A-C-C-C-C-G-G-A-A-T-G-A-T-T will change into AUG GGG CCU UAC UAA and every three codes represent a triplet codon that translates into an amino acid first code called start codon and normally code for methionine (AUG) and last code for stop and does not code any amino acid.
Then, the amino acid will be - methionine-glycine-proline-tyrosine -stop codon
