A camel has a hump to store water so it can survive in its desert environment. Which kind of adaptation is this?
A camel’s hump is an example of
adaptation.
Answer:
Camels actually store FAT and not water in their hump. This is called structural adaption.
Explanation:
Camels’ unique physiology and adaptations allow them to survive, even in the harshest conditions of the desert. Camels have thick fur to protect them from the heat, fat hump to serve as food storage, they rarely sweat, and can go for weeks without water. These are only a few reasons how camels survive in the desert, even without water.

What is paleontology?
State two economic importance of bacteria.
Paleontology is the science of the form of life existing in former geologic periods, as represented by their fossils.
____
Bacteria are ubiquitous one-celled organisms, spherical, spiral, or rod-shaped and appearing singly or in chains, comprising the Schizmycota, a phylum of the kingdom Monera (in some classification systems the plant class Schizmycetes), various species of which are involved in fermentation, putrefaction, infectious diseases, or nitrogen fixation.
Bacteria play major role in decomposition, agriculture and industries.They are a part of human life.There are both beneficial and harmful effects of bacteria.In decomposition:
They decompose dead plant and animal wastes, such as fallen leaves, and animal biological wastes.
Production of organic manure:
Manure is created by decomposing animal wastes such as dung and plant wastes.
Treatment of sewage:
Anaerobic decomposition by bacteria is used to convert wastes in sewage water to energy and purify the water.
Production of biogas:
It contributes to biogas plants by converting manure and household wastes to methane, which can then be utilized as fuel.
Nitrogen fixing through biological means
Rhizobium aids in symbiotic nitrogen fixation, whereas Nitrosomonas, Nitrobacter, and Nitrococcus aid in nitrogen conversion from one form to another.
Importance in medicine, industry, and biotechnology
Microbes are a source of antibiotics and vaccines in human and veterinary medicine for the treatment and prevention of infectious illnesses.
Dairy:
Curd and other milk products are mass-produced in factories using Lactobacillus curdling of milk.
Antibiotics:
Antibiotics are microorganism-produced chemicals that kill or inhibit other bacteria and are used to treat infectious illness. Molds like Penicillium and bacteria like Streptomyces and Bacillus create antibiotics in nature.
Vaccines
Vaccines are microorganism-derived compounds used to immunize against illness. Vaccines are often derived from the microorganisms that cause infectious illness. To immunize against diphtheria, a toxoid form of the diphtheria toxin is employed, and portions of Bordetella pertussis cells are utilized to vaccinate against pertussis (whooping cough). Smallpox, polio, diphtheria, tetanus, and whooping cough vaccinations have almost eliminated these illnesses in places of the world where they have been used.
Biotechnology
Microbiology contributes significantly to biotechnology, a branch of science that applies microbial genetics to biological processes in order to produce valuable molecules. Microorganisms are critical components of recombinant DNA technology and genetic engineering. Microbial cells, microbial DNA, and microbial enzymes are important technological tools.
Many biological products and biological processes have genetic information that may be introduced into microorganisms to genetically engineer them to produce a chemical or perform an activity. The genes can come from any biological source, including humans, animals, plants, and microorganisms. This allows for the microbial production of meals, fuels, enzymes, hormones, diagnostic agents, medications, antibiotics, vaccines, antibodies, natural pesticides and fertilizers, and a variety of other chemicals helpful in our civilization and society. Furthermore, the microbial genes that encode for these chemicals, the most of which are unknown, represent a wealth of knowledge for use in medicine, pharmacy, agriculture, food science, and biotechnology.
Harmful effects:
Causes diseases to plants and animals. Many human diseases are caused by bacterias.Spoilage of food.Bacteria have numerous ecological and biological importance.
Answer:
Some of the halophilic archaea carry some processes which are economically very important such as biodegradation, bioremediation and environmental processes.

This year, druehl, inc. , will produce hot water heaters at its plant in delaware, in order to meet expected global demand. To accomplish this, each laborer at the plant will work hours per month. If the labor productivity at the plant is hot water heaters per labor hour, how many laborers are employed at the plant?.
2400 laborers are employed at the plant in given case.
What do you mean by global demand?The overall demand around the globe for a good or service is called global demand.
N should represent the number of workers engaged at the plant. The total number of heaters made by all employees in an hour is:
watts = 0.15 watts per hour * N
The total number of heaters in a month will be:
heating units = 0.15 * N * 160
This must be 57600 to satisfy the anticipated demand, so:
If we solve for N using 57600 = 0.15 * N * 160, we get:
N = 57600 / (0.15 * 160) = 2400 laborers.

Imagine an instance where there are two parents, and both have polydactyly, a trait which is determined in this example by a singel gene. They have four children, one of hwom have polydactyly. what is the probailty their next child witll have polydactyly
The probability that their next child will have polydactyly is 0.75
What is Polydactyly?Polydactyly may be characterized as a circumstance in which an individual has more fingers or toes as compared to normal.
In humans, it occurs due to the homozygous mutants for a HOXD13, and due to which digits are joined and a condition known as Polysyndactyly occurs.
If both parents carry the genotype heterozygous for Polydactyly, i.e. Pp, the resultant offspring will have the genotypes PP, Pp, Pp, and pp. In which pp is normal, while all the three are affected due to the expression of dominant allele causing Polydactyly.
Now, according to the question, only one of the offspring possess the genotype of pp, hence the probability of their next child will have polydactyly is [tex]\frac{3}{4}[/tex] = 0.75.
Therefore, the probability that their next child will have polydactyly is 0.75.

What is the process of cellular respiration?The process of cellular respiration releases energy. In order to liberate energy from foods and create ATP (adenosine triphosphate), the molecule that transports energy in cells, a metabolic process takes place in the cells of living things.
Organic substances, like glucose, are broken down in a sequence of enzyme processes that release the stored energy, which is then collected in the form of ATP, during cellular respiration.
Since this process takes place in the presence of oxygen, it is also known as aerobic respiration. Living organisms depend on cellular respiration to survive because it helps in the transportation of the energy needed for all of their cellular functions.
