Answer:
To a 1st Grader:
Carbon is the magic element that is the basis of life on Earth. All living things contain carbon. Animals breathe it out, and plants breathe it in. Plants, people and animals depend on each other.
The carbon cycle is a process where carbon dioxide travels from the atmosphere into living organisms and the Earth, then back into the atmosphere. Plants take carbon dioxide from the air along with water and photosynthesis from the sun and use it to make food.
Explanation:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. To a first grader is different because they wouldn't understand what half of these words mean lol.
The carbon cycle is the biogeochemical cycle that exchanges carbon between the Earth's biosphere, parallel layers, geosphere, hydrosphere, and atmosphere.
What is the importance of carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the atmosphere into organisms on Earth and then back into the atmosphere.
The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, atmosphere, and living organisms.
The carbon cycle is critical to the survival of life on Earth. Nature has a tendency to maintain carbon levels in balance.
This means that the amount of carbon naturally released from reservoirs equals the amount naturally absorbed by reservoirs. Maintaining this carbon balance ensures that the planet remains habitable for life.
Thus, by regulating the rate of carbon dioxide in the atmosphere, the carbon cycle plays an important role in regulating Earth's global temperature and climate.

This is because clearing a forest destroys habitats and therefore kills animals as they have no shelter, no food source and no water source.
Describe the modification of FGF5 pre-mRNA that leads to the production of both the FGF5-L and FGF5-S proteins.
Answer:
Splicing of exons and exclusion of introns
-mRNA that is transcribed from DNA usually has large regions of genetic code that just do not code for anything. This is a pretty conserved phenomenon among eukaryotes, to have meaningless sequences of DNA (introns) separating the meaningful sequences of DNA (exons). Introns must be spliced out of mRNA so that its translation leads to a functional protein.

Which statement best describes the evolution of hominid structure over time?
The size of the skull decreased.
O The size of the brain cavity increased.
O The shape of the head became flatter.
The shape of the teeth became more pointed.
Answer:
The size of the brain cavity increased.
Explanation:
Over the years the brain cavity got bigger and so did our brain and that is why humans are smarter
The evolution of hominid structure over time involved the increase in the size of the brain cavity.
What is evolution?Evolution refers to the gradual and cumulative changes that occurred in organisms over a long period of time which made them more complex and which they were able to transmit to their offspring.
The hominids were the ancestors of the modern day humans.
Through the process of evolution, the size of the brain cavity increased in hominids resulting in larger brains and more complexity as seen in modern humans today.
Therefore, the increase in the brain cavity of hominids occurred through the process of evolution.

All cells come from parent cells that exchange DNA.
All living things are composed of single cells or multiple cells.
All cells grow and develop until they reach a certain size, at which point they die.
All cells are equipped with structures that enable motion, such as pseudopods or flagella.
All living things are composed of single cells or multiple cells. Therefore, option B is correct.
What is cell theory?Cell theory is given by Schleiden and Schwann. According to this theory, cells make up every biological entity; they are the basic building block of life, and all life originates from earlier forms of life. Today, the cell idea has become one of the guiding concepts of biology due to its widespread acceptance.
A cell is the lowest form of life. This indicates that a cell cannot be divided into smaller units and yet be considered to be alive. An entire organism, such as a person, can be divided into smaller parts, such as organ systems, organs, and tissues.
Organisms can be unicellular or multicellular. Therefore, option B is correct.

An exotic species is the same as an invasive species.
True
False
Answer:
False
Explanation:
Exotic species are species brought to and unfamiliar environment, just like invasive species. There is a difference between the two however. Exotic species are indeed not native to their environment, but unlike invasive species, they are not harmful to the ecosystem. In order for an exotic species to become invasive, it must out-compete native organisms for food and therefore cause harm to the ecosystem. Non-native species that do not out-compete species remain exotic and not a high risk of disrupting the ecosystem.

This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you
Answer:
In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.
The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.

Answer:
Heterotrophy, Autotrophy
Reasoning: Heterotrophy organisms are organisms who can't retrieve food themselves and use energy and sunlight in order to get their food, which is exactly what plant cells do. Autotrophy is the ability to produce things such as carbon dioxide and oxygen, which plants do as well. Hence, Heterotrophy and Autotrophy are the most reasonable answers.

Answer:
Incomplete dominance
Explanation:
In genetics, incomplete dominance refers to an inheritance mode in which two gene variants (i.e., alleles) of the same locus combine in a way that neither allele dominates the other. This phenomenon is similar to codominance, but in this last case, both alleles are dominant. Incomplete dominance produces a new phenotypic trait resulting from the combination of both non-dominant alleles. An example of incomplete dominance includes the pink color of snapdragons resulting from the cross of red-flowered snapdragons with white-flowered snapdragons.

What type of microbe is used in a vaccine .
Answer:
answer is below
Explanation:
Several of these structures have been used to generate bacterial vaccines. Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria.
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.

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.
