Answer:
Tetanus is a very aggressive disease generated by clostridium tetani, this clostridium, which is a bactera, releases a toxin that generates tetanization of the muscle, where it contracts massively and simultaneously, remaining over time, similar to a contracture and very different from synchronized and sporadic contraction that requires locomotion or other physiological contractions.
The Tetanus toxin acts as a toxin for the muscle cells that make up the skeletal muscle fiber, which unfortunately leads to the progressive death of the patient who suffers from it.
In simple words, tetanus generates muscle spasms that are maintained over time, preventing the function of the organ, that is, of the muscles, immobilizing them and prohibiting them from other movements.
Patients who reach the target are affected by the diaphragm that contributes to respiration, therefore many of the tetanized patients die in a similar way to suffocation due to a constant spasm of the diaphragm.
Explanation:
The bacterium is found in sporulated form on the ground or on oxidized surfaces, that is why it is important to sterilize oxidized elements or to decontaminate them, and to apply the antithetical vaccine, which is what prevents them from suffering from said pathology.
In simple words, the great differences between a physiological contraction of muscle fibers and tetanized contractions is the time in which they occur, since tetanization lasts over time and physiological does not, and the power of contraction in tetanization is greater. , since the toxin of said bacterium potentiates the ionic channels thus generating an increase in the contractile capacity of the muscle fiber compared to the physiological or health situation.
In order for the toxin to have an effect, the bacteria must leave its sporulated state, release the toxin and the wound must be deep enough for the bacteria to enter the bloodstream, after which the toxin enters the myocytes that are muscle fiber cells intensifying muscle spasms by opening calcium channels in a longer period of time, calcium channels are those found in the REL of myocytes, which act as a reserve for this ion, triggering so that the Z lines of the sarcomeros definitively approach spasmodically by shortening the length of the sarcomero.

In the previous activity, you chose an animal that interested you and listed three examples of innate behavior and three examples of learned behavior for that animal. Now research what, if any, courtship and mating rituals this animal has. Explain why you think it has or doesn’t have these behaviors.
Answer:
what grade
Explanation:
Courtship and mating rituals are diverse and can vary greatly among different animal species. They are typically involved in attracting mates, establishing pair bonds, and ensuring successful reproduction.
1. Courtship and Mating Rituals Exist: Many animal species have elaborate courtship and mating rituals. These behaviors can serve various purposes, such as displaying fitness and attractiveness to potential mates, establishing territory, or demonstrating parental abilities.
2. Absence of Courtship and Mating Rituals: Some animal species may not exhibit elaborate courtship or mating rituals. This can occur in species where mating opportunities are abundant or where the reproductive process is straightforward without the need for elaborate displays.
The presence or absence of courtship and mating rituals can depend on various factors, including ecological pressures, social structure, reproductive strategies, and evolutionary history of the species. Different species have evolved different strategies to maximize their reproductive success, and these strategies can manifest as complex courtship rituals or simpler methods of attracting mates.

The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.
The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.
In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.
Thus, the selected option is correct.
A video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.
What is Population?A population is defined as the complete set of individuals, whether that group includes a nation or a group of people with a common characteristic which is the pool of individuals from which a statistical sample is drawn for a study. .
It is described as a unit of biological community made up of a permanent group of an interbreeding individual of a species found in a space or geographic region at a particular time.

A. carbon dioxide, oxygen
B. oxygen, carbon dioxide
Answer:
A. carbon dioxide, oxygen
Explanation:
Photosynthesis is a process that certain organisms (plants, algae and some bacteria) undergo to produce their own food. The equation for photosynthesis is:
water + carbon dioxide + light energy —> glucose + oxygen
In photosynthesis, the plant takes water, carbon dioxide and light energy from the sun and turns it into glucose (sugar, or the food) and oxygen.
Therefore, the correct answer is A. carbon dioxide, oxygen. The plant will use carbon dioxide and then release oxygen as a waste product.
Look at the following mutation: AUG-GUC-CCU-AAA → AUG-AGU-CCC-UAA-A. The base A was inserted following the start codon AUG. Describe how this mutation affects the encoded amino acid sequence.
Answer: Non sense mutation took place over here.
Explanation:
Mutation took place over here where, the base A was inserted in place of the start codon AUG.
This states that the last codon will code for a stop signal instead of amino acid.
This is a type of non sense mutation when the ribosome is stopped from reading a stretch of mRNA because a stop codon is present over there.
The original set of codon is replaced by the stop codon and the protein synthesis is stopped.
When there is an alteration in the genetic bases of codes that can lead to modification in the phenotype or the genotype of an organism is called a mutation.
The type of mutation that occurred in the given sequence is a non-sense mutation.
The mutation can be explained as:
The mutation changed the reading frame of the triplets from the second place after the AUG or the start codon.The last codon in the unmutated sequence AAA was for lysine (lys) but in the mutated sequence is changed to UAA (stop codon) which codes for the termination of the chain.The mutation in stop codons are called non-sense mutation and now it will signal for termination instead of coding for another amino acid.When the process of translation gets terminated and the ribosomes stop translating due to mutation then it is called a nonsense mutation.Therefore, the process will terminate due to replacement by a stop codon.

Express a
mass of 0.014 mg in grams
Answer:
14 mg
Explanation:
1 g = 10³ mg = 1000 mg
0.014 g * 1000 mg/1g = 14 mg
0.014mg in grams would be equal to 1.4 × 10^-5 gram.
What are unit conversions?There are a few items that we track in our daily activities, including the following:
Speed \sTemperature \sArea \sVolume \sMass
Units of measure are needed in order to measure these values. Sometimes the units of measurement employed may not correspond to the standards required for a particular process or application, as well as the measuring choice and convenience.
It's crucial to convert these units in a way that makes sense and can be used effectively. Let's use the example of someone who is only familiar with the metric system to better grasp the statement.
The person finds it difficult to determine the height of a 25-foot tree. The individual will comprehend the height of the tree better if they convert 25 feet to meters.
