to any 8th graders or 7th graders that take technology, what are you currently learning in technology class?

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.

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.

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.

"The correct answer is C. Converting an old shopping mall into a community college. Option C  is an example of redevelopment.

Redevelopment typically refers to the process of taking an existing property or area and transforming it for a new use, often to revitalize or improve the area. Here's the reasoning for each option:

A. Drawing an urban growth boundary around an area is an example of urban planning and land-use regulation, but it does not involve the transformation of existing structures or land use within the boundary. Therefore, it is not an example of redevelopment.

B. Converting rural pastureland into a new shopping center is an example of development, as it involves creating a new structure or use on previously undeveloped land. This is not redevelopment because the land was not previously developed for another purpose.

C. Converting an old shopping mall into a community college is a clear example of redevelopment. It involves taking an existing structure that was used for one purpose (retail) and repurposing it for a completely different use (education). This fits the definition of redevelopment as it revitalizes the property and gives it a new function.

D. Putting a parking garage on an unused lot inside a city is also an example of development rather than redevelopment. While it does involve constructing a new structure, the lot was previously unused, so there is no transformation from a previous use to a new use, which is a key aspect of redevelopment.

Therefore, option C is the correct choice as it best exemplifies the concept of redevelopment."

Explanation:

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.

It 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.

I thinks the answer is c,from hormones to glands to endocrine target cells

The brain communicates with the endocrine system via neuroendocrine cells to neurons. Neuroendocrine cells receive messages from nerve cells and release hormones into the bloodstream.

Messages sent by the brain to the endocrine system pass from neuroendocrine cells to neurons for translation (Option A). In the body, neuroendocrine cells are special cells that receive neuronal input (neurotransmitters released by nerve cells) and, in response to this input, release message molecules (hormones) into the bloodstream. This allows for communication from the nervous system to the endocrine system.

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

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.

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.

A conductor allows heat and electrical charge to pass through easily, facilitating heat transfer through conduction and convection; an insulator does not allow heat or charge to move through it easily, limiting heat transfer mainly to radiation.

The difference between a conductor and an insulator lies in their ability to transfer heat and electrical charge. A conductor, such as metals like copper, aluminum, and silver, allows heat and electrical charge to pass through it easily because of the movement of electrons within the material. Conductors can transfer heat through physical contact (conduction) as well as by the movement of the material itself (convection). On the other hand, an insulator like wood, plastic, or rubber does not allow heat or electrical charge to move through it easily, primarily restricting heat transfer to radiation, which does not require direct contact.

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:

These conditions prevent the action of bacteria and other decomposers, allowing soft tissues to remain intact over millions of years.
