Natural Selection is defined as the evolutionary process in which the organism better adapted to the environment will have higher chances of survival and reproduction.
Natural selection can be caused by mutations, genetic diversity, and other behavior of the organisms.
Altruistic behavior is a type of behavior in which the other person or organism benefits from the cost of oneself.
For example, worker bees show altruism in which they perform selfless works like protecting the nest and forage for the food, which benefit the other bees but decrease their fitness.
The worker bees are undergoing continuous labor and are sterile. Thus, the bees work for others at the cost of themselves, showing altruism.

The tubulin protein is a major component of?
A: flagella and mosses
B ferns and cilia
C flagella and cilia
D volvox and mosses
HELPP
Answer:
C flagella and cilia are the answer
The tubulin protein is a major component of flagella and cilia. The correct option is C.
What is tubulin protein?In molecular biology, the term "tubulin" can refer to either the tubulin protein superfamily of globular proteins or one of its constituent proteins. Microtubules, a crucial part of the eukaryotic cytoskeleton, are created when - and -tubulins polymerize.
Highly conserved - and -tubulin heterodimers produce dynamic microtubules that carry out a variety of vital cellular tasks, including force generation during cell division, structural support, and transport route. Two polypeptide subunits make up tubulin, and dimers of these subunits connect to form protofilaments, which are very long strands.
Therefore, the correct option is C. flagella and cilia.

A scientist is trying to isolate a penicillin-resistant His- bacterial mutant from a mixed population. To isolate penicillin-resistant mutants, the scientist must inoculate the parent population on plates containing ______; this approach is ______ selection.
Answer:
Penicillin, direct
Explanation:
this scientist has to inoculate the parent population using plates that contains penicillin in them. we call this approach the direct selection.
In the direct selection, bacteria is grown on a material that has penicillin in it. the goal is to find mutants that have resistance to penicillin. only these resistant ones would grow and then a direct identification would be done.
What would happen to ecosystems without producers in the food chain A.Without producers, there would be no food for consumers and decomposers. The food chain would collapse. B.Without producers, the food chain would only include plants such as trees and shrubs. The food chain would not contain consumers or decomposers. C.Without producers, only aquatic ecosystems and their food chains would exist. D.Without producers, only consumers and decomposers of ecosystems would survive in the food chain.
Answer:
c
Explanation:
If there are no producers in the food chain, then there would be no food for the consumers and decomposers and the food chain will collapse. Thus, the correct option will be A.
What is a food chain?A food chain can be defined as a linear network of links in a food web with the starting organism from the producers and ending at an apex with the predator species, detritivores, or the decomposer species.
Plants can make their own food through the process called as photosynthesis. Using the energy from the solar radiation (sun), water and carbon dioxide from the atmosphere and other nutrients, they chemically synthesize their own food. Since, they can make or produce their own food they are known as the producers.
Therefore, the correct option will be A.

Explain how temperature and pH levels can influence microbial infections in the body
Temperature and pH levels can influence microbial infections in the body.
Microbes have their optimum pH and temperature conditions in which they can function properly . They can survive in particular range of pH and temperature.
If the conditions in human body do not match the range in which they can exist , the microbes will not be able to grow or reproduce and they'll ultimately die.
pH and temperature outside the adequate range ( for microorganism) may cause denaturation of proteins and enzymes of the microorganism which will lead to their death.

Answer:
Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. In animals, this process is brought about by osmoreceptors, which can detect changes in osmotic pressure. Humans and most other warm-blooded organisms have osmoreceptors in the hypothalamus. Besides the brain, osmoregulators are also found in the kidneys..

QUESTION 7 Consider the results you saw for the pigment paper chromatography experiment in the final part of the lab. Spinach was the source of pigments, and spinach leaves are normally a dark green color. However, when we ran the pigments on the chromatography paper, we discovered that light yellow and orange-yellow bands appeared. Why couldn't we see these colors on the spinch leaves themselves
Answer:
Hello the options to your question is missing below are the missing options
the collected spinach leaves must have been contaminated by some kind of yellow leaves the nonpolar solvent must have altered the color of these pigments as it passed through them the yellow pigments are partial breakdown products as the chlorophyll degrades the chlorophyll a is present in much higher concentrations, so dominates the leaf's appearanceanswer : the chlorophyll a is present in much higher concentrations, so dominates the leaf's appearance ( 4 )
Explanation:
We couldn't see these colors on the spinach leaves because the chlorophyll a is present in much bigger concentrations so it dominates the leaf's appearance
This is because The light yellow and orange yellow pigments on the spinach are the carotenoid pigments. (fat soluble pigments) and they absorb light and they change colors. but since the chlorophyll is present in high concentrations there colors won't be visible

Serpins are naturally occurring proteins that serve as serine protease inhibitors. Serpins bind to the enzyme and are cleaved, but the acyl enzyme intermediate cannot behydrolyzed leading to irreversible inhibition. One of the serpins is a potent inhibitor of the serine protease trypsin and, as expected, contains an arginine at the site of cleavage. Using arrows to show the flow of electrons, draw the mechanism for theinhibition of trypsin by this serpin, labeling all intermediates. Draw the side chains of important enzyme amino acids, and show all hydrogen bonding within the enzyme-substrate complex. Also be sure to include the important arginine on the inhibitor including its side chain.
Answer:
Explanation:
The serpins are components of human plasma and its mutations result in numerous genetic diseases, such as caused by the deficiency of α 1 -antitrypsin. They are proteins of high molecular mass (350-500 amino acids) and have been identified in numerous organisms, from viruses to mammals. The serpins interact with the target enzyme by a similar mechanism on a substrate, although an irreversible interaction where the bond occurs serpin adopts different conformations to interact with the protease target, causing a deformation of the active site of the protease.
The mechanism of inhibition of Trypsin by serpin can be seen in the image below.
