What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased? The small fish and wading birds would be affected. Only the small fish would be affected. The small fish, bivalves, and invertebrates would be affected. The entire food web would be affected.
Answer: The entire food web
Explanation: Because the small fish eat the plankton and the birds eat the fish, and other things eat the birds etc. etc., technically if the number of phytoplankton and vegetation dropped, it would cause everyone else to have a lack of food
Answer:The entire food web
Explanation: I took the test
Examine the diagram of the food web described in the passage. Using arrows, how would you label the direction of energy flow through this web?A:Starting at the edges and and flowing toward the shrimp. B: Starting at shrimp and flowing outward. C: Starting at the plankton and flowing upward.D: Starting at the birds and flowing downward
Answer:
c.
Explanation:
The food web starts as the plankton are eaten by worms and mollusks, which are eaten by shrimp, which are eaten by crabs and fish, and fish eat the shrimp, and birds eat the crabs, shrimp, and fish. I hope my answer helps.
Starting at the plankton and flowing upward. Therefore, option (C) is correct.
What is flow of energy in food web?A food web describes the transfer of energy and nutrients from one organism to another within an ecosystem. The flow of energy in a food web starts with producers, such as plants or algae, which convert energy from the sun into organic matter through photosynthesis. This organic matter is then consumed by herbivores, which are then consumed by carnivores or omnivores, and so on. Each level of the food web represents a trophic level, with energy and nutrients being passed up the chain as organisms consume one another.
As energy moves up the food web, some of it is lost through various processes such as respiration, heat loss, and waste production. This means that the amount of energy available at each trophic level decreases, resulting in a pyramid-shaped structure of the food web. The flow of energy through a food web is essential for maintaining the balance and stability of an ecosystem, as it determines the survival and population of different organisms within it.

Which sources would preserve the soft tissues of an early mammal
Answer:
Amber , permafrost and tar
Explanation:
Amber , permafrost and tar would preserve the soft tissues of an early mammal. Soft tissues of early mammals would preserve in case of amber in Russia. and frozen soil in the Arctic. Although hair and mammary glands are soft tissue but they are not readily fossilized as mammary glands and hairs are derived from dermic structures
Soft tissue preservation is rare and requires rapid burial in environments that are oxygen-free and low-energy. Examples of such preservation include burial in volcanic ash, trapping in amber, and freezing in glaciers. These conditions help prevent decay and allow soft tissues to remain intact over time.
Soft tissue preservation is rare due to the need for rapid burial to prevent bacterial decay. Such preservation typically occurs in environments that are oxygen-free and low-energy. Examples include:
Burial in volcanic ash, which rapidly covers and preserves remains.Trapping in amber, as seen in perfectly preserved ancient insects.Frozen in glaciers, as evidenced by preserved mammoths with intact skin and hair.These conditions prevent the action of bacteria and other decomposers, allowing soft tissues to remain intact over millions of years.
Question 6
Which kingdoms have some organisms that can make their own food (autotrophic)?
The kingdoms that contain autotrophic organisms are Eubacteria, Plantae, Fungi, Protista, Archaebacteria.
This is the case because These 5 kingdoms all have organisms that make their own food rather than eating other organisms for food like heterotrophs do. This is why kingdom animalia doesn't have any autotrophs because they can only get energy from other organisms.
There are three main kingdoms that have organisms that can make their own food excluding the kingdom of protista and fungi. These kingdoms include:Kingdom Plantae, kingdom Eubacteria and Kingdom Archaebacteria,.
Kingdom Plantae is the most familiar and well-known of the three kingdoms. It includes plants, which are well known for their ability to use energy from the sunlight to produce their own food through a process which is called photosynthesis.
The other two kingdoms which are named asEubacteria and Archaebacteria, are groups of bacteria. Some bacteria are able to perform photosynthesis or chemosynthesis, which is a process that allows them to convert inorganic molecules into energy-rich organic compounds without the need for sunlight.
Eubacteria and Archeobacteria:
Individuals of these kingdoms are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus. Monera are usually very tiny, although one type, namely the blue-green bacteria, which look like algae.
Protista:
Protists are single-celled organisms and usually move by cilia, flagella, or by amoeboid mechanisms. The have no cell wall, although some forms possess a cell wall.
Fungi
Fungi are multicellular,with a cell wall, organelles including a nucleus, but have no chloroplasts. They have no mechanisms for locomotion. Fungi can range in size from microscopic to very large ( such as mushrooms). Nutrients are acquired by absorption.
Plantae
Plants are multicellular and most of them don't move, although gametes of some plants move using cilia or flagella. Organelles which include nucleus, chloroplasts are present, even cell walls are present. Nutrients are acquired by photosynthesis .
Animalia
Animals acquire nutrients by ingestion.
Thus, organisms belonging to Kingdom Plantae, kingdom Eubacteria and Kingdom Archaebacteria are organisms which can make their own food.

What molecules are made during transcription
Answer:
During transcription, only one strand of DNA is usually copied. This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand
Explanation:
The RNA molecules are produced during the process of transcription.
TranscriptionIt is the first step in decoding the genetic information of the cell.
It is the process by which the information in a DNA strand is copied into a novel molecule of mRNA.
At the time of transcription, the enzymes known as RNA polymerases construct the molecules of RNA, which are complementary to a part of one strand of the double helix of DNA.
The prime enzyme, which takes part in the process of transcription is RNA polymerase.
Thus, the molecules of RNA are produced during transcription.

Answer:
The answer to the question is
D. It initially caused a large drop in chicken pox cases in the united states and the rate continues to decrease.
Explanation:
The varicella vaccine introduced in 1995 led to a significant reduction in chickenpox cases in the United States, demonstrating the effectiveness of vaccines in controlling and managing infectious diseases.
Explanation:Based on the information and the graph depicting the number of varicella (chicken pox) cases between 1972 to 2011, it can be concluded that the introduction of the varicella vaccine in 1995 had a significant impact on the reduction of chicken pox cases in the United States. Following the vaccine's introduction, there was a notable decline in virus spread. As seen with many other vaccines such as smallpox, measles, mumps, and polio, the targeted immunization measures tend to significantly reduce the prevalence of the associated diseases.
Once a person is vaccinated, the body develops immunity against the virus, significantly reducing the chances of infection. It's also important to note that, similar to diseases like polio, the successful reduction of chickenpox cases through vaccination showcases the importance and effectiveness of vaccines in controlling and managing infectious diseases on a broad scale.
