Atmospheric changes from the burning of fossil fuels that affect plant life are Increases in ozone levels slow plant growth and acid rain removes nutrients from the soil.
How does acid rain affect plants?Acidic water that touches plants can erode epidermal tissue, especially in the chloroplasts of leaves so that the photosynthetic ability of plants is reduced. This erosion of epidermal tissue makes plants more susceptible to drought and is also attacked by various kinds of pests and diseases and insects
Excessive UV-B radiation can inhibit plant metabolism so that growth grows slower and becomes stunted. The impact of exposure to UV-B rays in aquatic ecosystems hurts the distribution of phytoplankton which forms the basis of the food chain in the waters.
Burning fossil fuels releases various air pollutants such as toxic gases and particulate molecules.

c) excessive waste products in the blood on glomerular filtration rate
d) blood pressure on glomerular filtration rate
In this activity, we will explore the effect of ption d-blood pressure on glomerular filtration rate
Glomerular filtration takes place as a result of a pressure difference in the glomerulus. GFR generally increases with increasing volume of blood pressure and heart rate. GFR is lowered when the nociceptors arterioles entering the glomerulus constrict as well as the efferent arterioles leaving the glomerulus dilate. Hypertension has been shown to increase urinary protein excretion, the thickness of the glomerular basement membrane, and the glomerular filtration rate in both glomerulonephritis and normal kidneys.

The finger like projections that are present on the surface of the intestine were called as villi
why are villi present on the surface of the intestine ?
The small intestine's mucosal wall develops millions of tiny finger-like projections called villi.
It expands the surface area for greater nutrient absorption.
The absorption process is mostly controlled by the small intestine.
The small intestine has villosa to expand the absorption surface area.
On the other hand, the stomach is an organ that mostly temporarily stores food and aids in the digestion of proteins.

This research interestingly showed that the events that cause axon destruction do in fact morphologically resemble Wallerian degeneration in mammals: Severed axons remain intact for a defined latent phase of 6–8 h, then exhibit beading and cytoskeletal breakdown, and finally undergo complete fragmentation.
Similar to this, adult Drosophila brain primary cultures' PDF+ CNS axons that were cut showed degeneration within a day (Ayaz et al. 2008).
But looking at how WldS modifies disease models can provide some hints.

describe how modeling the evolution of the fully developed eye can be seen as an overall model of the process of evolution by natural selection.
Early eyes may have been simple eyespots that could only distinguish between light and dark. Later, some animals developed spherical eyes that could focus light onto an image.
Critical to the eyes that form these images was the development of lenses that could focus the light. The complex human eye may have evolved through natural selection acting on small changes, from simple patches of light-sensitive cells to producing sharp images. Not in an obvious way, but possible further intermediates were certainly advantageous. Many scientists are fascinated by studying the evolution of the eye because the eye is a clear example of similar organs found in many animal forms. Simple light detection is found in bacteria, protozoa, plants and animals. This review traces the evolution of vision from a putative origin in cyanobacteria to humans. Circadian clocks, phototropism, and phototaxis require the ability to detect light. Photosensory proteins allow us to reconstruct the molecular phylogenetic tree.

Similar to how protein enzymes work, ribozymes are RNA molecules with the capacity to catalyze particular biochemical processes, such as RNA splicing in gene expression. It can function as a protein enzyme in a cell, catalyzing biochemical and metabolic processes because of its clearly defined tertiary structure.

the ans regulation of blood pressure is involuntary, yet biofeedback techniques enable individuals to reduce their pulse rate and blood pressure. explain how this occurs.
High blood pressure and pulse rate of the individual are reduced by the biofeedback method in which an individual's physiological parameters are visualized in instruments based on values in instrument blood pressure and pulse rate can be reduced by therapies.
Biofeedback is a technique in which individuals are trained to control their involuntary body function which is usually controlled by ANS (Autonomic Nervous System). This is possible because individuals who are in biofeedback therapy sessions are monitored by equipment that can sense physiological functions. This equipment converts physiological signals into auditory, and visual signals hence the patient and therapist can see or hear how the body is reacting to stimuli. Through techniques suggested by therapists, patients can control involuntary physiological functions of the body. Using biofeedback equipment physiological parameters like breathing rate, heart rhythm, finger temperature, and muscle activity of patients with high blood pressure will be collected. On basis of the physiological parameters, the result therapist will design a training program for the patient.
