The main structural distinction between the left atrium and the right atrium is that the left atrium has the _____, and the right atrium does not.
a. auricle
b. pectinate muscles
c. cardiac muscles
d. chordae tendinae

Answers

Given our understanding of cardiac anatomy, we can confirm that the main structural distinction is that the right atrium has the pectinate muscles, while the left one does not.

Firstly, we must address that there is a wording issue with the question. In reality, it is the right atrium that contains the pectinate muscles. The remaining options either correspond to both atrium, or neither.

The auricle is another word for ear. This is a cavity present on both the right and left atrium which allows them to extend their blood carrying capacity in situations of need. This option cannot be correct for the question since both atria possess one.

As for options b and c, cardiac muscle is present in the entirety of the heart. Cardiac muscle is the muscular cells that make up every wall and cavity of the heart and allow it to complete its unique function. Chordae tendinae, are fibers present in the ventriculus that attach the walls to the tricuspid valve, these are not present in either of the atria.

Therefore, we can confirm that though the wording is off, the intended correct answer is pectinate muscles, given that the right atrium is characterized by their presence, whilst the left atrium contains few, if any, of these muscles.

What is system of biological classification?

The modern system of biological classification is the classification that involves the naming and arrangement of organisms in groups according to a hierarchical order.

In this type of classification, organisms are given scientific names based on their genus and the species.

This pattern of double naming is called binomial nomenclature consisting of two names.

Therefore, in the modern system of biological classification the genus and species names are used for the scientific name of organisms.

Why do fossils that paleontologists find represent only a partial picture of life in the past?

Answers

Answer:

Because we cannot see some animals properly like jellyfish as their tissue is too soft, and feathers or for can often not make an imprint on fossils.

Explanation:

Answer:

Fossils: They are remains of animals or plants in the past that were somehow preserved and buried under the earth's crust.

One fossil can only give us a glimpse into the history of the time that particular animal or plant lived or breathed on the earth. For example, a fossil remains of a particular species of dinosaur would only provide information of the time when that species lived on earth and other information related to that particular time. Fossil remains of dinosaurs would not give us information on the time during the ice age or any other time in history.

Explanation:

The study of various fossils can give us information about the development and evolution of living organisms over time but there are limitations to it.It may happen if we compare the fossil remains of an organism that existed billions of years ago we may find a time gap where there is no fossil evidence found so it creates a loop in information.Also, the process of fossilization is complex and long. Many species of the past became extinct without fossilization so we can never get information related to those extinct species.Thus, because of this reason we can say that fossils don't provide us with complete information about the past.

Why can't humans regrow limbs?

Answers

Answer:In fact, most of our organs have some turnover in cells, which explains why they're younger than our biological age. The human heart, skin, intestines, and even our bones are slowly replaced over time, meaning that a limited amount of damage can be reduced. However, this doesn't extend to limbs.

Explanation:

Answer:

Humans have stem cells, but they aren't readily available to assist in healing. Because most other mammals are similar, they aren't very good at regeneration. Amphibians and some fish have more readily available stem cells, which are usually rather good at regeneration.(please mark brainliest <3)

a/an ___ is a blood clot attached to the interior wall of a vein or artery.

Answers

Answer: a thrombus

A thrombus may also form in your heart

A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.

Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.

Vaccines are given to provide protection against pathogen causing infections. Which of

Group of answer choices

A. Antibodies in the vaccine provide the body with nonspecific immunity to an antigen.

B. Fever and swelling develop which is the first response in killing a pathogen.

C. An inactivated or killed virus stimulates the body to develop specific immunity to that type of virus.

D. Heathy bacteria causes the body to release toxins which will protect the body if later exposed to different type of bacteria.

Answers

Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

The homologous structure to the forearm of humans is the leg of the horse.

What are homologous organs?

Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.

The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.

Homologous organs have different functions in organisms.

MPG A n n u a l T o n so fG H G At Sunny Middle School, Ms. Addisons class is investigating how greenhouse gases (GHGs) contribute to global climate change. They wrote their research on note cards: Greenhouse gases cause climate change by trapping heat on the planet. Greenhouse gases contribute to smog and air pollution, which can cause respiratory diseases, like asthma. Extreme weather, disruptions to the food supply, and increased wildfires are also caused by greenhouse gases. Where do greenhouse gases come from? Mia asked. One of the most common greenhouse gases is carbon dioxide, also known as CO2. People release CO2 into the atmosphere when we burn fossil fuels (like coal and natural gas) for energy and transportation, Ms. Addison answered. The class examined the graph to the right. The source for the largest percentage of CO2 emissions for a typical household was vehicles. The students conducted some research and found: > Highway vehicles release about 1.7 billion tons of GHGs each year. > Each gallon of gasoline burned creates 20 pounds of GHG. > A typical vehicle releases 6 to 9 tons of GHG into the atmosphere each year. For their group project, Mia and Ichiro researched hybrid cars that combine gas and an electric motor. Awesome, so it consumes less fuel and emits less CO2 into the environment, Ichiro said. While hybrid cars are better for the environment, Im seeing that some people are hesitant to buy one because of the higher purchase price, Mia noted. They found the graph to the right, which shows the miles per gallon (MPG) and the annual tons of GHG produced by 8 different types of cars. If each gallon of gasoline burned created 20 pounds of GHG, and the price of gasoline was $2.454 per gallon, how much money was saved annually on gas by the car that got 40 miles per gallon when compared to the car that got 20 miles per gallon?
