what would happen if the trna synthetase for proline added lysine instead of proline to the proline trnas in a particular cell? explain your answer in no more than 3 sentences, including the consequences for the proteins made by the cell and the cell itself.
If the tRNA synthetase for proline adds lysine instead of proline to the proline tRNAs in a particular cell, it will lead to mistranslation.
Mistranslation occurs when tRNA carries the wrong amino acid, leading to the addition of wrong amino acid in the nascent protein produced.
The mistranslated protein produced may get misfolded, leading to dire consequences inside the cell that can result in disease/disorder. It is found that the addition of lysine instead of proline will result in amyloid formation (Prions) and, thus lead to neurodegenerative diseases.

a population of small fish is introduced into a large lake (lake grande). the lake has regions of different depths, from shallow to deep, with different oxygen levels and algal (fish food) populations. another population of the same species of fish is introduced into a small, uniform pond (wee lac). after many generations, which body of water will have more species of fish?
More fish species will be present in large lake water depends on environmental factors.
Simply, large bodies of water are known for producing large fish. It's simple to assume that larger lakes would hold greater fishspecies , so do so. Arctic seas and surrounding waterways are home to 400 different kinds of fish, the majority of which live on or the bottom. Therefore, the Pacific wins for having the greatest marine life based on worldwide fisheries and the total richness of coral reef ecosystems. Distribution and abundance in lakes and reservoirs in North America are influenced by biological factors like availability of food and competing with other fish species, as well as environmental factors like lake elevation, water quality, and lake form.

true or false? during atrial contraction, the papillary muscles are relaxed, and av valves are open
TRUE. During atrial contraction, the papillary muscles are relaxed and av valves are open..
The cardiac cycle is accompanied by brief negative deflections in the primarily forward-moving blood in the veins caused by atrial contraction of the heart, which produces pulse waves that are conveyed from the heart into the venous system.
Just before ventricular systole, atrial contraction gives the ventricular volume one more boost. When the pressure in the ventricle surpasses the pressure in the atrium due to ventricular contraction, the mitral valve closes.
The atrial contraction, also known as the atrial kick, is the last stage. It occurs when the cardiac muscle in the atrium contracts, increasing pressure and causing more blood to flow past the mitral valve. 20% to 30% of the total diastolic volume crosses the mitral valve at this final stage.

The first step in the proton-proton chain produces an antielectron, or positron. What happens to the positron?.
An antielectron, or positron, is created in the proton-proton chain's first phase. When it collides with an ordinary electron, it quickly transforms into energy, causing matter-antimatter annihilation.
The opposite of an electron is a proton. The primary distinction between them and electrons is their positive charge. Positrons are created during the decay of nuclides that have more protons than neutrons in their nucleus. These radionuclides release a neutrino and a positron when they decay.
With the exception of having the opposite charge and spin, antimatter particles are almost similar to their counterparts in matter. When antimatter and matter collide, they instantly disintegrate into energy.

The correct answer is telomerase protects the ends of chromosomes from nucleases and helps in maintaining the integrity of linear chromosomes.
What is telomerase?
It is an enzyme present in eukaryotes that repairs the telomeres of the chromosome so that they do not become progressively shorter during chromosome replication.
It is the enzyme responsible for the addition of guanine-rich repetitive sequences. Its activity is exhibited in gametes and stem and tumor cells.
Telomerase protects the ends of chromosomes by binding at an RNA molecule that contains a sequence complementary to the telomeric repeat.
Let us discuss other statements:
Without the replication of telomeres, it becomes too short and chromosomes reach a critical length and can no longer be replicated so the cell dies.Telomeres are found at the ends of the chromosome of only eukaryotic organisms.Telomeres are composed of repetitive sequences of six base pairs, TTAGG. With each cell division, some of the telomeres are lost.

the green wavelength is irrelevant to photosynthetic organisms that use chlorophyll a and chlorophyll b because they mainly absorb which two colors of light?
Both chlorophyll a and chlorophyll b absorb blue and red light wavelengths and reflect green light wavelengths during photosynthesis.
Chlorophyll a and Chlorophyll b are the two chlorophyll pigments that are essential for plants to absorb light during photosynthesis. When a pigment exhibits high absorption at a given wavelength, it is capturing that light at that wavelength to produce energy. If there is a low absorption, the plant is reflecting the light back. Chlorophylls a and b both reflect green light while absorbing blue and red light waves. In the violet and red parts, chlorophyll peaks, whereas in the blue and orange regions are where chlorophyll b peaks. In the green area, their absorption is extremely low. Because chlorophyll is a green pigment, leaves that have it as their main pigment are also green. Chlorophyll reflects some yellow wavelengths, but the green color of the leaves is only visible when yellow and deep green wavelengths are combined.

The human body is divided into several cavities. List these cavities and propose reasons why evolution has favored this configuration.
In order to supply living creatures with the necessary adaptations and efficiency, evolution has led to complexity in body design. The bodily cavity, also known as the coelom, is a fluid-filled region where organs like the heart, lungs, stomach, and intestines can grow, expand, and move. In humans the body cavity has been divided into dorsal, thoracic, abdominal and pelvic cavities on the basis of their body position and the organs lodged there. The fluid in the body cavity keeps all the body organs hydrated and also provides a sort of hydrostatic support. It also helps to maintain homeostasis within the body.
The evolution of living things reveals that they began as aquatic prokaryotes, progressed to aquatic eukaryotes, and eventually became multicellular creatures that gradually adapted to life on land. The evolutionary tree's pinnacle or greatest level is seen as being human. The body cavity gives the intricate internal organs the environment they require to work properly. Evolution produced the many bodily compartments in humans because each function in the body has specialized organs that work separately yet together.
