Conservation is using materials and resources wisely to protect the environment.
Conservation activities involve businesses, international organizations, and certain governments. The UN promotes the establishment of national parks all around the world. In order to increase awareness of and water conservation, the UN also created World Water Day.Governments pass legislation outlining the proper use of land as well as the locations that should be preserved as parks and wildlife refuges. Along with enforcing these rules, governments also require industries to build pollution-control equipment in order to safeguard the environment. Last but not least, governments frequently offer incentives for resource conservation, the employment of clean technology, and the recycling of obsolete items.There are several global organizations devoted to conservation.

Medical researchers have developed a new cream for treating skin rashes. To test their cream they set up an experiment where one group of patients used the new cream for two weeks, and a second group used no cream.
In each group, the number of people whose skin condition got better and the number whose condition got worse are recorded below. Because patients do not always complete studies, the total number of patients in each of the two groups is not exactly the same.
Of 298 patients who used the cream, 223 found their rash got better and 75 found their rash got worse.
Of 128 patients who used no cream, 107 found their rash got better and 21 found their rash got worse.
What numbers should you compare to determine whether the cream is effective?
1) 298 v 128
2) 223 v 107
3) 75 v 21
4) 75/223 v 21/107
5) 223/330 v 75/330
6) 223/298 v 107/128
7) 223/298 v 75/298
Answer: #6
Explanation:
For each group, find the ratio of #patients better/total # of patients
In this case, it would be 223/298 and 107/128. These ratios can be used for further calculations.

Explanation:
How is the nucleus, the rough endoplasmic reticulum, the Golgi apparatus and vesicles involved in making sure that cells have the proteins they need?
The cell nucleus contains genes to generate mRNAs which are translated into proteins that pass to the endomembrane system to be processed into final proteins.
What is the endomembrane system?The endomembrane system is a group of organelles and structures inside the cell (i.e., the rough endoplasmic reticulum, the Golgi apparatus and vesicles) that act in a sequential form to process proteins and transport them to their final destination within the cell or exported to outside the cell.
This system acts together the cell nucleus whose function is to store the genetic material (DNA) required to produce proteins in their prior form (before folding and processing).
In conclusion, the cell nucleus contains genes that generate mRNAs which are translated into proteins that pass to the endomembrane system (rough endoplasmic reticulum, the Golgi apparatus and vesicles) in order to produce final proteins.

The statements that is true about ozone (O₃) is as follows:
It is a pollutant in the troposphereIt filters out very little UV-A radiation in the stratosphereThe correct answer is option C.
What is ozone?Ozone is an allotrope of oxygen with symbol O₃ having three atoms in the molecule instead of the usual two.
The ozone layer refers to a region of the stratosphere containing a relatively high concentration of ozone, which absorbs most solar ultraviolet radiation.
Although majority of ozone is found in the stratosphere, the little amount found in the troposphere is a gaseous pollutant.
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen.

A bird or fish if there is a loss or change in energy
birds and Fish need energy to maintain basic metabolic activities and to support growth, reproduction, activity, and health. Proteins, carbohydrates, and lipids (the macronutrients) provide this energy and also some essential nutrients.
What are the energy sources of fish and birds?Protein is a major energy source for all fish and birds, and it appears that blood glucose may derive more readily through gluconeogenesis than directly from dietary carbohydrates.
Whit this information we can conclude that Protein is used for fish growth if adequate levels of fats and carbohydrates (energy) are present in the diet. If not, the more expensive protein can be used for energy and life support rather than growth.

what are the 3 constant variables?
Constant variables are all the variables whose values or states remain the same in an experiment to avoid their influence on results. Constant variables that could apply to the experiment: City, Schedule, Ticket Cost.
What is a constant variable?
Several variables are involved in an experiment. Among them are the ones in which the researcher is interested and the ones that are not of interest.
Constant variables are the ones in which the researcher is NOT interested. But since these variables might influence the results, the researcher needs to keep them constant to avoid affecting the dependent variable response.
So, constant variables are all the variables whose values or states remain the same in an experiment.
In the exposed example we need to identify three POTENTIAL constant variables. So first, we will identify the question, the independent and dependent variables, and then we will propose the three constant variables.
Question: Did the day of the week impact on how many fans attended the concerts?
Independent variable: days of the week

Lion Phylogeny: Finding connections Based only on eht DNA which populations do you think live closer in proximity to each other
The depiction of the evolutionary history and connections between groupings of species is known as phylogeny. The findings are shown in a phylogenetic tree, which shows connections based on common or divergent morphological and genetic features.
The word "phylogeny" comes from Haeckel's 1866 introduction of the German Phylogenie, and the Darwinian approach to categorization got recognized as the "phyletic" approach.
By observing the given DNA samples of the different lion species, we can say that Cameroon, Tsavo, Fannie Roberta, Umfolozi, Zimbabwe, Zambia, and Kalahari lions are linked together and divided from Sabi sands, Botswana, and Etosha lions due to differences in their cytochrome b gene. The complete division will be as follows.
This phylogenetic tree explains that all the given species have originated from a common ancestor who had T (thymine) nucleotide in the DNA at some sites. The thymine changed to C (cytosine) to develop new species. This change was done by a point mutation.

3816543
Explanation:
20^15 or 3.28. 10^19
That is roughly equivalent to 4.3 billion times the world population today (in just 20 amino acids). The beauty of proteins is their complexity and seemingly infinite possible permutations. Moreover, a single polypeptide chain can have many different tertiary structures. Polypeptide chains can then join together to form quaternary structures. Among these proteins can be an antibody for ovarian cancer, an antimalaria haemoglobin or a antitoxin for heavy metals. There are just so many proteins we do not know yet.

Much like when we sweat, this allows the plant to cool and maintain homeostasis. we should also know that most Plants take in carbon dioxide and release oxygen. Did you know they also regulate how much they take in and let out? Leaves have stomata, holes on the underside, that expand and contract to get just the right combination. That's homeostasis.
Explanation: Environmental factors may affect the plants. However, they maintain the internal conditions by self-regulation, known as homeostasis, to adjust to the changing environment. This includes maintenance of the plant's internal temperature and fluid.

8. In which ranges of pH will amylase cease to function?
Click or tap here to enter text.
The pH level of 4.5 to 7 was discovered to be where -amylase functions at its best. The activity of the enzyme is reduced when the pH of the enzyme solution is lowered below this range.
Nearly all animals have a significant amount of amylase in their pancreas. However, it is also present in many species' livers, salivary glands, and small bowel mucosa; the levels of amylase in these tissues vary greatly between species. The ideal pH for the interaction between starch and amylase is 7. The rate of reaction will be slowed down by PH levels that are high or low than this number. Between pH 3 and pH 11, amylase is active. The morphology of a site of the enzyme is impacted by PH variations, which has an impact on the enzyme's capacity to bond with its adsorbates. Amylase levels that are high in the blood or urine can indicate: Acute pancreatitis (sudden) - an obstruction in a pancreatic duct, a tiny tube either benign (non cancerous) tumor or pancreatic cancer.
