Answer:
1. dopamine and serotonin
2. brain and spinal cord
3. controls the function of different processes in the body
4. limbic system
5. Increase brain surface area
6. release hormones into the bloodstream
7. insulation
8. laughing has multiple positive functions in the body
Explanation:
Dopamine is a neurotransmitter (i.e., a chemical messenger) involved in responses to rewards, motivation and memory, while serotonin is another neurotransmitter that controls appetite, mood, wakefulness and sleep onset. The central nervous system (CNS) consists of the brain and spinal cord. The spinal cord acts as a conduit by which messages are sent from the brain to the body and from the body to the brain. Moreover, the brain acts to control all body abilities (e.g., thinking, talk, feeling, walking, breathing, etc). The autonomic nervous system is known to modulate different processes (e.g., blood pressure, digestion, breath) and internal organs (e.g., heart) by acting largely unconsciously, i.e., without a person's conscious effort. The limbic system is a part of the brain that acts to control emotions and memory by modulating autonomic/endocrine functions. Convolutions, folds, and fissures can increase brain surface area, thereby more neurons are packed into the cortex of the brain and thus it is possible to process more information. The endocrine system acts to release hormones into the bloodstream. These hormones travel in the blood to their target cells/tissues, where they regulate different functions (e.g., mood, growth, development, metabolism, reproduction, etc). The myelin is an insulating layer surrounding nerve cells that enables electrical impulses to transmit efficiently around the whole body. Laughing has multiple positive functions: release endorphin hormones that decrease stress, increases the number of immune cells and antibodies, stimulate the activity of internal organs (e.g., heart), quickly relax the muscles, contribute to increase the oxygen uptake rate in blood, etc.

The central dogma describes which of the following?
the process by which enzymes are modified after translation
the way DNA is replicated
the flow of genetic information
the way RNA is used as a template to make DNA
Answer:
The correct answer is - the flow of genetic information.
Explanation:
The process includes the flow of genetic information or instructions encoded in DNA used to make or turn to a final product that can be DNA or protein, known as the central dogma.
Mostly central dogma term use for the protein synthesis from the DNA that takes place in the two steps, transcription is the first converts DNA into RNA and the second translation that converts product of the first step that is RNA into Protein. DNA → RNA → protein.
Thus, the correct answer is - the flow of genetic information.
The central dogma describes the flow of genetic information. The correct option is C.
A key idea in molecular biology known as the core dogma outlines how genetic information moves through cells. It says that RNA is translated into proteins from transcribed DNA.
This idea emphasises how genes are expressed and proteins are made in living things by sequentially transferring genetic information from DNA through RNA to proteins.
The fundamental dogma excludes DNA replication, the reverse transcription of RNA into DNA, and the process of post-translational enzyme modification.
Thus, the correct option is C.

Which one of these is not a human effect on the water cycle?
Developed areas prevent soil from absorbing rainwater
Precipitation is increasing in deserts due to an increase in water use
Air pollutants also wash back into the land and water bodies from precipitation
Storm water runoff carries pollution
Answer:
Precipitation is increasing in deserts due to an increase in water use
Explanation:
Just see for yourself
The one that is not a human effect on the water cycle is precipitation is increasing in deserts due to an increase in water use. The correct option is B.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
One of the most essential elements of human life is water. There is water all over. It passes through your house as well as rivers, mountains, lakes, and oceans. Without water, neither humans nor any other species could survive.
In the majority of deserts, the air's moisture content is very low. In the dry air, light raindrops frequently evaporate before they can reach the ground. Rainstorms can occasionally appear as ferocious cloudbursts.
Therefore, the correct option is B. Precipitation is increasing in deserts due to an increase in water use.

You observe two distinct behavioral strategies among flocks of house sparrows. In one strategy, individuals (producers) search for food patches. In the other strategy, individuals (scroungers) wait for producers to find food and then feed in the patches found by the producers. The relative frequency of these strategies differs in flocks, and you observe that the scroungers have high fitness (a high feeding rate) when they are rare in a flock and low fitness when they are common in a flock. What is one possibility for the persistence of the two phenotypes in this population
Answer:
Frequency-dependent selection
Explanation:
Frequency-dependent selection is a type of natural selection where the fitness or reproductive success of a particular phenotype/genotype in the population is dependent on its frequency in the population. This type of natural selection can be both positive or negative. Frequency-dependent selection is a critical process that helps to maintain the genetic variability at population and species levels. A known example of frequency-dependent selection (positive) is the mimicry of butterflies, where selection can favor non-poisonous butterflies that show the same colors as poisonous butterflies.

Which factor contributed most to the development of the cell theory?
The factor that contributed most to the development of the cell theory is the advancement in technology.
With advancements in the area of technology, significant improvements were made to the primitive microscope initially invented by the likes of Hans and Zacharias Janssen, and more powerful microscopes like the electron microscopes were invented. With these, details of the cell could be observed and all the organelles could be studied, including how the cell divides (give rise to another cell).
Still on the technological advancement, the discovery of differential staining materials made it possible to differentiate several biological phenomena as they relate to the cell.
Thus, by extensively studying the cell using microscopes and differential staining dyes, the cell theory was developed by the likes of Theodore Schwann, Mathias Schleiden and Rudolf Virchow.

Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.

75%
50%
25%
Answer:
50%
Explanation:
If you use a punnet square with Rr x rr you will get 50% white
50% of the offspring should have white flowers when we cross a hybrid genotype for red flowers with pure recessive for white flowers shown in the Punnett square. So, the correct option is C.
What is Punnett square?Punnett square is defined as the diagram that represents the possible genotypes of the offspring developed after a reproductive event. It was first developed by geneticist Reginald Punnett where the possible genotypes of the offspring are represented in a tabular form with each box in the table representing an event of fertilization.
For above given example,
Rr genotype represents the red flowers.
rr genotype represents the white flowers.
The Punnett square will be:
R r
r Rr rr
r Rr rr
So, 50% have red flowers while 50% have white flowers.
