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.

A. Describe how the biomass in the bluegill fish trophic level of a biomass pyramid would be
different from the biomass in the aquatic plants trophic level of the same pyramid.
The biomass would be different because aquatic plants are producers while bluegill fishes are consumers.
Pyramid of biomassIn a food chain or food web, the biomass of the population of organisms at the lower trophic levels is usually more than that at the higher trophic level.
Thus, producers tend to have more biomass than primary consumers. Primary consumers tend to have more biomass than secondary consumers.
In the same vein, secondary consumers have more biomass than tertiary consumers.
Bluegill fishes are consumers while aquatic plants are producers. Thus the biomass of aquatic plants would be more than that of bluegill fish.

Natural resources are spread equally within a city is that true ?
sunflower follows the direction of the sun until they reach the age of maturity. why?
Continuously facing towards the east also helps the flowers to heat up quickly. This gives them an advantage in pollination, as warm flowers attract insects. Therefore, in the plant's interest, the flower always faces the sun and is therefore always clearly visible to these important pollinators.
This property of facing the sun is mostly observed in young flowerheads and generally stops once the flower starts to mature. The phenomenon of flowers following the sun across the sky is called heliotropism.
Why do sunflowers face the sun?The obvious reason for the flower following the sun would be to maximize photosynthesis.
Each sunflower plant has only one flower on its stem. Therefore, during pollination, the plant’s only means of reproducing must get noticed by pollinators. [A pollinator is anything that helps carry pollen from the male part of the flower to the female part of the same or another flower. The movement of pollen must occur for the plant to become fertilized and produce fruits, seeds, and young plants.] Continuously facing towards the east also helps the flowers to heat up quickly.
This gives them an advantage in pollination, as warm flowers attract insects. Therefore, in the plant’s interest, the flower always faces the sun and is therefore always clearly visible to these important pollinators.
When researchers compared mature flowers facing east with flowers that they had turned to face west, they made a remarkable observation. East-facing blooms attracted five times as many pollinating insects as west-facing ones. Sunflower has a clear advantage in terms of reproduction if it faces the sun.
Why a mature sunflower does not track the sun?- It is mainly young flower heads that exhibit this characteristic of heliotropism because younger flowers have green “bracts” that look like a mane.
- As sunflowers mature, this process comes to a halt. Overall growth slows, and the flower's circadian clock reacts most intensely to the sun's early morning rays than those later in the day. As a result, the blooms gradually stop tracking westward altogether.

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.
