Go to Settings
Answer: A
Explanation:
Lobes were the beginning of arms and legs, the correct option is A.
What are lobe-finned fish?Lobe-finned fish, unlike other fish, have a core protuberance in their fins that contains many bones and muscles.
The fins are extremely flexible and may be useful for supporting the body on land, as seen in lungfish and tetrapods.
The majority of bony fish have ray fins. These thin fins are made up of skin webs that cover flexible spines. Lobe-finned fish, on the other hand, have fins that look like stumps.
The lobe-finned fishes are the ray-finned fishes' sister group. They are distinguished by paired, fleshy pectoral and pelvic fins espoused by a single bone.
Prehistoric records clearly show that terrestrial vertebrates evolved nearly 400 million years ago from lobe-finned fishes.
Thus, the correct option is A.

Answer:
A.) conversion of chemical energy to heat energy
D.) Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
D.) The populations of marsh snails and painted turtles will decrease.
Explanation:
When energy is stored in wood, it is being stored as chemical energy. This energy is being stored in the bonds that hold the wood molecules together. Once you begin to burn the wood, these bonds are breaking. As this happens, the chemical energy turns into heat energy (aka. thermal energy) and is released into the atmosphere.
Photosynthesis converts light energy from the sun into chemical energy that can be accessed by the plant later. During cellular respiration, the plant breaks down the molecules which store the energy in the form of chemical energy and accesses the energy.
When you decreases the amount of phytoplankton, the marsh snails have less food to feed on. As a result, more phytoplankton will starve. This results in the decrease of the marsh snail population. Because the marsh snail population decreases, the same will happen to the painted turtles.

Why have plants been implicated in the devonian glaciations and not in the proterozoic glaciations?
The reason why plants have been implicated in the devonian glaciations and not in the proterozoic glaciations is; Land plants had not yet evolved during the Proterozoic.
Why have plants been dying?The Devonian glaciation occurred in south America and caused a global narrowing of the warm climatic belts, sharp regression, increased clastic sedimentation.
Meanwhile, the Proterozoic glaciation occurred near sea level in low palaeolatitudes. Thus, we can say that the reasons why plants have been implicated in the devonian glaciations and not in the proterozoic glaciations is because land plants had not yet evolved during the Proterozoic.

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.
