Answer:
Heredity is a process from which traits are transferred from parents to offspring and it is related to genetics because trades are controlled by genes known as genetic code which code the traits.
Explanation:
Which cell organelle contains coded directions for production of proteins? Question 3 options: endoplasmic reticulum lysosome Golgi apparatus nucleus
Answer: nucleus
Explanation: The nucleus contains the DNA which is a genetic material that contains all the instructions for protein synthesis. Before proteins are produced, the DNA is first of all copied into an single stranded RNA in a process known as transcription. This process takes place in the nucleus. The single stranded RNA then leaves the nucleus to the ribosome where protein synthesis takes place, there the RNA is translated into a polypeptide chain.

What was the reaction when the cell theory was first introduced.
Answer:
Many scientists opposed the "cell theory" when it was first introduced because they believed that even "non-living matters" could produce or generate a living tissue. This was called "spontaneous generation." The appearance of the fly's larva (maggots) on meat supported this belief of theirs.
It was Louis Pasteur who was able to disprove this concept.
Explanation:
The discovery of cell came about when the microscope was invented. It was first discovered by Robert Hooke, an English natural philosopher in the 1600s. However, he wasn't really sure about the structure and function of the cell during his time. It was Anton van Leeuwenhoek, a Dutch scientist, who proposed that "motility" is a quality of life.
Developing the cell theory was credited to Theodor Schwann and Matthias Schleiden.
What are scientist doing to Pork to make it a GMO?
Answer:
They use a gene modification technique called CRIPSR-CAS9. The pigs have been given a gene that allows them to better regulate their own body temperature, whereby they burn fat, or at which animals consume their own fat.
Explanation:
British and Chinese scientists explained that they conducted the study by adding a mouse version of the UCP1 gene used for porcine embryos, which is used to regulate body temperature characteristic of most mammals, but not ordinary pigs.
It is problematic for pigs to maintain a stable body temperature, and this is especially complicated in pigs that are cold in the winter months because they have not been able to "store" fat.
Inserting the UCP2 gene could solve this problem.
How does esrth’s rotation affects ocean currents
Answer:
Because the Earth is spinning faster at the equator than at the poles, wind currents are created. The winds pull surface water, creating ocean currents.
Explanation:
a
the reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration.
b
the products of cellular respiration are the reactants of photosynthesis.
c
the reactants of photosynthesis are the reactants of cellular respiration.
d
the products of cellular respiration are the products of photosynthesis.
Final answer:
The statement 'the products of cellular respiration are the reactants of photosynthesis' explains the reciprocal relationship between these two processes, highlighting the cycle of matter and energy in biological systems. So the correct option is b.
Explanation:
The correct statement about the relationship between the reactants and products of photosynthesis and cellular respiration is that the products of cellular respiration are the reactants of photosynthesis. Photosynthesis uses carbon dioxide and water to produce glucose and oxygen. Conversely, cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate).
Statement b of the question, 'the products of cellular respiration are the reactants of photosynthesis,' highlights this reciprocal relationship. By examining the equations for both processes, we can see they are the reverse of each other, signifying their direct connection to the carbon cycle.
What phase is Homologous chromosome paired.
In metaphase I of meiosis I, the pairs of homologous chromosomes, also known as bivalents or tetrads, line up in a random order along the metaphase plate. The random orientation is another way for cells to introduce genetic variation.
Discuss how biodiversity affect the increase and decline of the elephant population
Biodiversity supports elephant populations by ensuring ecosystem health, but overpopulation of elephants can harm biodiversity. Ivory poaching is a major threat to elephants, causing declines despite an international trade ban. Stable political systems and managed property rights for hunting licenses have been associated with increased elephant populations in some African countries.
Biodiversity's Impact on Elephant Populations
The relationship between biodiversity and elephant populations is complex. High levels of biodiversity can support robust elephant populations, as diverse ecosystems tend to be healthier and more resilient. However, the impact of elephants on biodiversity can be dual-faceted; they can enhance biodiversity through their role as ecosystem engineers or cause its decline by overgrazing, particularly when their numbers exceed the carrying capacity of their habitat. Poaching, primarily for ivory, remains the most significant threat to elephants, leading to dramatic population declines. Despite an international ban on the ivory trade, forest elephants continue to suffer serious losses in range and numbers.
Analysis by Professors McPherson and Nieswiadomy has shown that elephant populations have rebounded in African nations with stable political systems and proper management strategies, such as establishing property rights in licenses to hunt elephants. These nations, including Botswana and Zimbabwe, have seen elephant numbers increase significantly. Conversely, elephant populations have declined in countries with unstable political systems and inadequate property rights. As human population growth in Sub-Saharan Africa continues, the pressure on elephant habitats and the region's biodiversity is likely to intensify, potentially leading to increased human-wildlife conflicts and further declines in elephant populations.
Preliminary treatment includes wastewater screening and blank
Preliminary treatment in wastewater treatment entails methods like wastewater screening and sedimentation. Screening catches large solids that could potentially damage the machinery. Meanwhile, sedimentation or grit removal takes away heavy particles that add undue wear and tear on the plant's machinery.
Explanation:Preliminary treatment in wastewater handling comprises of procedures such as wastewater screening and sedimentation. Wastewater screening is deployed as a first step, which is vital in blocking large objects that could possibly damage the wastewater treatment facilities or intervene with following processes. Objects such as rags, wood fragments, plastic, and other solids are intercepted at this stage.
Following screening, sedimentation or grit removal occurs. This process helps in the removal of sand, small stones, broken glass, and other heavy particles that could cause undue wear and tear on the facility's machinery. An example of how these processes aid in maintaining the natural environment can be noticed in the selective precipitation method used in treating water from manufacturing facilities. This specific process eliminates detrimental ions such as phosphate (PO4³-) which results in minimizing algae growth, thereby protecting marine life and human health.

Final answer:
Preliminary treatment of wastewater includes the removal of large solids through screening and grit removal before moving on to primary treatment where organic solids, fat, and grease are settled or floated out. Secondary and tertiary treatments follow, further breaking down organic matter and filtering the water, respectively, with disinfection being the final step.
Explanation:
Preliminary treatment of wastewater includes wastewater screening and grit removal (the removal of sand and gravel) to protect the subsequent processes from being damaged by large and abrasive objects.After these larger solids are removed, the water then goes through primary treatment, which involves the settling or floatation to remove organic solids, fat, and grease. At this stage, a significant amount of sludge is produced, which may go through further treatment to be used safely as a fertilizer, although the presence of contaminants can be a challenge.The subsequent steps in the wastewater treatment process, beyond preliminary and primary treatments, include secondary treatment which harnesses aerobic bacterial decomposition to break down organic solids. This step is critical because it significantly reduces the biological oxygen demand (BOD) of the wastewater.Finally, tertiary treatment further refines the water by decomposing remaining nutrients and through additional filtration, followed by disinfection to eliminate bacteria, making the water safe for discharge or reuse.The plasma membrane is how many layers?

A cell uses which of the following to accelerate chemical reactions enabling its metabolic machinery to operate?
Which is a role of helpful bacteria?
removing nutrients from soil
producing oxygen
healing sick animals
preventing tooth decay
Answer:
Producing oxygen
Explanation:
Bacteria actually add to nutrients in soil because they decompose the organic matter such as dead bodies and such. I do not know if bacteria heal sick animals or if they prevent tooth decay rather I am sure they cause both of those.
Therefore, most plausible answer is producing oxygen because there are bacterias like cyanobacteria, or blue-green algae who go through photosynthesis and produce oxygen which is beneficial for all living beings.
Helpful bacteria helps in producing oxygen for carbon di oxide in th environment. Therefore, option (B) is correct.
What are helpful bacteria?Probiotics are live bacteria that are beneficial to our health, that help maintain a healthy balance of good and bad bacteria in our intestinal tract, that contribute to the digestion of food and that alleviate digestive issues such as bloating and diarrhea. Lactobacilli and Bifidobacterium are two types of bacteria that are considered to be examples of probiotics.
Through the process of photosynthesis, extremely minute bacteria known as prochlorococcus are busily converting carbon dioxide into the oxygen that we breathe.

Natural selection suggests that creatures with mutations disadvantageous to survival will not live to reproduce, yet there are examples, such as albino animals, found occasionally. Do these exceptions discredit natural selection? Explain your answer.
Answer:
yes the above statement is true.natural selection is not dis credit.
Explanation:
In order to support my answer we just take an example of mutation in an organism as the mutation in organism occur and is useful for the survival of the organism we called the mutation as the good mutation. Thus it is true that some mutation that cause disease and is disadvantageous for the survival of organism. Albino is a case studied here which is abnormal skin color and the skin color as the advantage to camouflage in the surrounding and the organism which can not camouflage will not survive properly because the can not protect them from the predator.
