Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.

What are Prokaryotes?

A prokaryote is defined as a single-celled organism that lacks a nucleus and other membrane-bound organelles. Prokaryotes were classified within the kingdom Prokaryota.

Prokaryotic cells are described as single-celled microorganisms that are the earliest known on Earth which include bacteria and archaea. Photosynthetic prokaryotes include cyanobacteria that photosynthesize that have a single cell membrane and, therefore, all reactions occur within the cytoplasm.

Bacteria are examples of the prokaryotic cell type, some example is E. coli.

Thus, Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.

The organism lower on the food chainThe organism higher on the food chainThe organism with a hard body rather than a soft bodyThe organism that lived in a marine or aquatic environment

Answer:

The organism higher on the food chain

Explanation:

The organism lower on the food chain. Their high reproduction rate, as well as their numerous populations, favor them at the moment of fossilizing under different environmental conditions.  The organism higher on the food chain. These organisms tend to be predators or bigger animals, characterized by small populations with a reduced number of individuals in comparison with smaller organisms. The fact that their reproductive rate is not very high, that they live longer and hence they are fewer in number, do not favor their fossilizing possibilities under different environmental conditions.The organism with a hard body rather than a soft body. Hard tissues always increase the possibilities of fossilizing, as their biological or mechanical destruction is not as easy as the destruction of the soft tissues.  The organism that lived in a marine or aquatic environment. It seems that those organisms that live in a sedimentary environment, such as the sea or a lake, or those that live buried or fixed to the bottom, have more possibilities of fossilizing.

What assumptions does the author make when presenting the information? Is there other historical data that should be considered before making such claims? *EASTER ISLAND*

Answers

The correct answer to this open question is the following.

The assumptions that the author makes when presenting the information are that the author makes a comparison of what could have happened on Easter Island to other places in the world that suffered a similar fate.

There is practically no other historical data that should be considered before making such claims. Indeed, what happened on Eastern Island, also called RAPA NUI by the natives, is a mystery. Yes, there are legends and oral tradition stories that refer to what could have happened, but nothing based on scientific terms that could be demonstrated. Theories varied form the possible scenario of the sinking of the Lemurian continent. Due to that incident, many natives decided to leave and sail to other regions of the planet such as Hawaii, the Polynesian islands, and of course, Easter Island.

How could the tomato plant’s response to being eaten by a hornworm caterpillar be described as a function of homeostasis?

Answers

Answer:

The required answer is given below:

Explanation:

This can be clarified with the idea of induced resistance. it is the capacity of a plant to react to the specific compound delivered from the damaged body parts, The dispersion of the synthetic animates all different plants parts and different plants to be less delectable and thusly not wonderful to eat. In this manner the more the degree of harm to the plant, the higher the volume of synthetic compounds delivered, and consequently the less delicious the plants and lower the harms negative criticism instruments. Since this reestablished the plants to moderately consistent inner environments, this is homeostasis.

Hornworm caterpillar harms tomatoes plants leaves, leaving holes. When a tomato plant is eaten, it discharges a compound substance called methyl jasmonate. The last would be gotten by adjoining plant parts or other tomato plants. The open tomato plants hence turn out to be less scrumptious. Subsequently, the caterpillar in the wake of crushing the underlying aspect of the tomato plants would not have the option to proceed with the taking care of and in this manner feed on each other prompting their death, turning them to cannabis caterpillars.  

Since trying to keep up the generally consistent interior condition plant discharges methyl jasmonate to forestall further harm and in this manner guarantees the soundness of the plant.

What type of antenna where Penzias and Wilson testing in 1962 that led to their discovery of one of the biggest piece
of evidence supporting the Big Bang Theory

Answers

In 1964, Bell Labs scientists Arno Penzias and Robert A. Wilson were conducting experiments with the Holmdel Horn Antenna, an extremely sensitive device originally used to detect radio waves that were bounced off Echo balloon satellites, and later Telstar, the first active communications satellite. These radio waves were so weak, that it became critical to eliminate all possible interference in order to detect them.

Despite taking all conceivable steps to eliminate interference, they continually detected a strange, buzzing noise that was coming from all parts of the sky at all times of day and night. They did a range of additional testing on the equipment, and even removed some pigeons that were nesting in the antenna and their associate detritus. Still, the sound persisted. They ultimately determined that the noise was coming from outside of our galaxy

Almost by chance, they later learned that researchers and astrophysicists Robert H. Dicke, Jim Peebles and David Wilkinson at nearby Princeton University were looking for a way to detect residual radiation that they believed would have resulted from the Big Bang. As it turned out, the radiation detected by Penzias and Wilson was a perfect match for what the Princeton researchers had predicted, and hence made history.

Arno Penzias (left), Robert Wilson (center) and Keith Jefferts (right) look through a model of the universe to the constellation Orion where, for the first time, they discovered carbon monoxide in outer space.

From the archives

An audio recording of the CMBR noise was captured and narrated by Robert A. Wilson. This discovery in 1964 by Penzias and Wilson, announced in a Bell Labs press release, earned the researchers a Nobel Prize in Physics and provided the basis for future astronomical discoveries.

The rate of species extinction on Earth is currently very high—perhaps as high as it has been since the time of the dinosaur extinction. Which of the following disruptions is not a major cause of this high extinction rate? a The hunting and overfishing of wildlife b The introduction by humans of invasive species into habitats c The use of animals in scientific research and experiments d The draining and filling of wetlands

Answers

Answer:

C. The use of animals in scientific research and experiments.

Explanation:

I got this answer correct when I took it.

The disruption which is not a major cause of a high extinction rate is: C. The use of animals in scientific research and experiments.

Extinction can be defined as a process or situation in which a species, family, or other taxonomic group of living organisms such as animals or plants become extinguished, destroyed, exterminated or dead.

This ultimately implies that, extinction literally means the extermination or dying out of a species, family, or other taxonomic group of living organisms.

Basically, the extinction of living organisms is mainly caused due to the effect of environmental forces and evolutionary changes such as:

Habitat fragmentation.Poor reproduction techniques.Natural disasters.Overexploitation of species by humans such as the hunting and overfishing of wildlife.Genetic inbreeding.An introduction of invasive species into natural habitats by humans.The artificial draining and filling of wetlands.

In conclusion, the disruption which isn't a major cause of a high extinction rate is the use of animals or plants in scientific research and experiments because often times they are not killed and only a sample of the population is used.

Which of the following describes the products of meiosis?

Answers

Answer:

Sry JK

Answer: In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.

The product of meiosis is four haploid daughter cells with genetically different as compared to their parents.

What is Meiosis?

Meiosis may be defined as the type of cell division in which a parent cell is able to synthesize four daughter cells that are haploid in nature. These daughter cells are genetically dissimilar with respect to their parents. It is also known as reductional division.

The process of meiosis generally occurs in the germ cells (sex cells) of males and females. The division of cells occurs twice in meiosis. Meiosis is generally completed in two steps that are as follows:

Meiosis IMeiosis II.

These steps are further divided into Prophase, Metaphase, Anaphase, and Telophase. Overall, it significantly determines the nature as well as the characteristics of a cell

Therefore, the product of meiosis is four haploid daughter cells with genetically different as compared to their parents.
