Which statement is incorrect about the adult human heart?
Question 28 options:
Blood in the right ventricle is deoxygenated.
Blood in the left ventricle is deoxygenated.
Blood in the pulmonary artery is deoxygenated.
Blood in the pulmonary vein is oxygenated.
Answer not listed
Answer:
B. Blood in the left ventricle is deoxygenated.
Explanation:
Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.
- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.
- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.
- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs
Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.

The human body organ known as the pancreas secretes the hormones insulin and glucagon. These hormones regulate the level
of glucose in the bloodstream. If the level of glucose is too low, the pancreas secretes glucagon which causes the glucose level
to increase; if the glucose level is too high, the hormone insulin will lower the glucose level.

A. population
B. community
C. biosphere
D. ecosystem
All of Earth's biomes considered together represent biosphere.
What is a biome?A biome is an amalgamation of plants and animals with similar traits for their habitat. Biomes can be found in many different locations. They are biological communities that have developed as a result of the area's common physical climate.
What is a biosphere?The biosphere is a small area of the earth's surface where soil, water, and air work together to support life. Only in this region is life possible.
What is a population?A population is a collection of people who can interbreed, share resources, or compete with one another for those resources.
What is a community?A community is defined as a collection of individuals belonging to various species who reside in the same region.
What is an ecosystem?An ecosystem is a biotic and abiotic component-based functioning unit of nature. Air, water, and soil are examples of abiotic components. The biotic components are producers, consumers, and decomposers.

For the global population growth rate to reach zero, the number of births would have to be
Answer:
same as the number of death
... is what you fill in.
Explanation:
If the death and birth number are equal, there are no changes in numbers made.
For the global population growth rate to reach zero, the number of births would have to be same as the number of death.
What do you mean by population growth rate?Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020.
Population in the world is, as of 2022, growing at a rate of around 0.84% per year (down from 1.05% in 2020, 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current population increase is estimated at 67 million people per year.
The world's population is expected to increase by nearly 2 billion persons in the next 30 years, from the current 8 billion to 9.7 billion in 2050 and could peak at nearly 10.4 billion in the mid-2080s.

Alice wanted to see if a new premium gasoline would give her more kilometres per litre. She filled her car with the new gasoline and went on a long trip. When she calculated her mileage, she discovered that she has gone 40 kilometres further on this tank of gas than she went on a tank of regular gas when she was driving around town as usual. She decided to buy the premium gas from then on to get better mileage. What are the errors in this experiment?

Explanation:
what is the water intake of chlorophytes
Answer:
Huge amount.
Explanation:
There is higher water intake of chlorophytes because the chlorophytes prepare their own food by using water and carbondioxide just like plants in the process of photosynthesis. These chlorophytes have chlorophyll which able these algae to make their food from sunlight and they can't live without water of dry places. Chlorophyte is also known as Prasinophyte which is a green algae. So due to photosynthesis, the chlorophytes needs high amount of water for making food.

Plants, like cacti, don't have leaves in the traditional sense. (Their spines are actually modified leaves.) But the cells in the body or “stem” of the cactus plant still contain chlorophyll. Thus, plants like cacti can absorb and convert energy from the sun through the process of photosynthesis

2- DNA replication, each strand of DNA serves as a _______ for a newly synthesized strand of DNA.
3- In gene expression, DNA is used as a template to make _______, which is then used as a template to make a polypeptide.
4- In the process of _______, DNA can be rearranged, which contributes to the genetic diversity of the species.
5- What are the differences between the structures of DNA and RNA?
6- How can the central dogma help us understand the process by which DNA is turned into protein? What are the two steps involved in the process of gene expression?
7- Why are replication and recombination two important roles of DNA?
Answer:
1.hydrogen
2.template
3.mRNA
4.recombination
5.DNA and RNA are both made up of nucleotides. RNA is comprised of adenine, uracil, guanine, and cytosine. DNA is made up of adenine, thymine, guanine, and cytosine. DNA is a double-stranded chain of nucleotides comprised of base pairs that form a double helix. RNA is often a single-stranded chain of nucleotides.
6.The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.
7.Replication is the duplication of DNA, and it is important because, in cell division, each daughter cell must contain an exact copy of the original cell's DNA, since DNA contains the instructions required to make all of the cell's tissues. Recombination is the natural process for genetic sequences in a chromosome or between chromosomes to exchange genetic information. Recombination is important in nature because it produces genetic variations that may be preserved because of natural selection. Recombination also can be used in the laboratory to combine the genetic code of two different organisms.

The idea that the brain of an infant is like a blank slate is known as: ____
a- tabula rasa
b-dry cup
c-cogito ergo sum
d-the empty brain
Answer:
a
Explanation:
The idea that the brain of an infant is like a blank slate is known as Tabula rasa. It is given in Locke's philosophy. Thus, the correct option is A.
What is Tabula rasa?Tabula rasa is the theory which describes that individuals are born without a built-in mental content, and therefore all the knowledge comes from experience or perception in life. The epistemological proponents of the tabula rasa disagree with the doctrine of innatism, that holds the fact that the mind is born already in possession of certain knowledge eithout experience.
In Locke's philosophy, tabula rasa was the theory that at birth the infant mind is a blank slate without rules for processing data, and the data is added and rules for processing are formed solely by one's sensory experiences in life.
Therefore, the correct option is A.
