When hair gets wet, the hydrogen bonds between keratin molecules in the hair are broken. These bonds are weak and temporary, but they help to maintain the shape and structure of the hair.
Other types of bonds between keratin molecules, such as disulfide bonds and salt bonds, are not typically affected by water. Disulfide bonds are strong and permanent, and they give hair its strength and elasticity. Salt bonds are also relatively strong, and they help to maintain the shape of the hair.
However, both types of bonds can be broken down by chemical treatments, such as hair relaxers or perms. In contrast, the hydrogen bonds broken by water can be re-formed when the hair dries, which is why hair often returns to its original shape after it has been wet.

Explanation:
1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.
2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents
3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit
4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant
A pea plant exhibits a recessive trait. Which statement is most likely true about the plant?
• The plant is identical to its parent plant.
• The plant has different alleles for the gene that codes for the trait.
• The plant has two identical alleles for the gene that codes for the trait.
The plant does not have the same genes for the trait as its parent plant.
Answers
The statement "The plant has two identical alleles for the gene that codes for the trait" is most likely true about the plant.
What is a recessive trait?A recessive trait is a characteristic or phenotype that is only expressed when an individual has two copies of a recessive allele, one inherited from each parent.
Recessive traits are masked by dominant traits in individuals who have one dominant allele and one recessive allele for the same gene. However, if an individual has two recessive alleles, they will express the recessive trait. Examples of recessive traits include blue eyes, red hair, and sickle cell anemia.

you are a conservation biologist studying a population of cheetahs that has no genetic variation within it at any locus because it has been at a small population size for a very long time. these cheetahs are about to be introduced into a new area without cheetahs. you can, for an extra expense, make sure that the introduced cheetahs refuse to mate with close relatives in the generation that they are introduced in order to reduce inbreeding depression. given what you know about the cause of inbreeding depression, and assuming that there are no new mutations, is this extra expense justified?
Answers
Given the causes of inbreeding depression, and assuming that there are no new mutations, this extra expense is justifiable because inbreeding depression will occur in this population if relatives mate, causing more homozygous recessive production than if random mating of individuals
The cheetah is heading towards extinction They face this problem as if we as conservation biologists have to save the cheetah from extinction if they are introduced to a relative and they refuse to mate with them for the new generation to reduce inbreeding depression.
Yes, because inbreeding depression would occur in this population if relatives mated, causing the production of more homozygous recessive if random individuals mated as when this happens, the few individuals end up with inbreeding which reduces the size of the gene pool leads to the decrement of genetic variability and the harmful mutation which is very difficult to adapt these changes.
Inbreeding depression is a decrease in fitness with increased genome-wide homozygosity that occurs in offspring from related parents.
The question type multiple choice:
a. Yes, because inbreeding depression does not depend on there being any genetic variation in a population.b. No, because of the absence of genetic variation.c. Yes, because inbreeding depression would occur in this population if relatives mated, causing the production of more homozygous recessives than if random individuals mated.d. No, because inbreeding would only result in the production of fewer heterozygotes in this population.The answer is C

Answers
The correct sequence of events which take place during gene expression will be 4 > 2 > 3 > 1.
The RNA polymerase will first bind to the promoter region of a given gene and then initiates the process of transcription. After this step, the spliceosome performs the function of removing the introns.
In the next step, hierarchical foldings take place in the primary structure of the the polypeptide chain which results in the formation of the tertiary structure of the polypeptide. The ribosome then basically binds the mRNA and then it uses the tRNAs to be able to translate mRNA into the the amino acid polypeptide sequence that it codes for.

•how can the use of hydroponics help increase the amount of food that can be grown on earth?
patulong po pls
Answers
The use of hydroponics can increase the amount of food grown on Earth by providing a controlled environment for plant growth, optimizing resource utilization, and allowing for year-round production. This method eliminates the need for traditional soil-based farming and enables efficient and sustainable cultivation of crops.
Hydroponics is a soilless cultivation technique that involves growing plants in nutrient-rich water solutions. It offers several advantages that can help increase food production on Earth. Firstly, hydroponics allows for precise control over the growing conditions, including nutrient levels, pH, and water availability. This ensures that plants receive optimal nutrition and can grow more efficiently, leading to higher yields.
Secondly, hydroponic systems can be set up in vertical structures or compact spaces, maximizing land utilization. This is especially valuable in urban areas or regions with limited arable land, where traditional agriculture may be challenging. Furthermore, hydroponics enables year-round production since it is not reliant on seasonal changes or weather conditions. With artificial lighting and climate control, plants can be grown continuously, increasing the overall food supply and reducing dependence on specific growing seasons.
Additionally, hydroponics uses water more efficiently compared to traditional farming methods. The closed-loop systems recirculate water, minimizing water loss through evaporation or runoff. This is particularly beneficial in water-scarce regions, where conservation is crucial for sustainable agriculture. Overall, the use of hydroponics presents a promising solution to increase food production on Earth by optimizing resource utilization, enabling year-round cultivation, and minimizing environmental impact.

III. Impermeable and hard seed coat results in the dormancy of the seed.
A
Only II
B
Only III
C
I and III
D
I, II and III
Answers
The correct answer is option (C) "I and III."
Both statements I and III are correct regarding seed dormancy. Statement II is incorrect.
Statement I states that seed dormancy is a result of endogenous control, which is true. Endogenous factors within the seed, such as hormones and genetic mechanisms, regulate the dormancy period and prevent germination until certain conditions are met.
Statement II suggests that delayed germination is advantageous to plants. However, this statement is incorrect. Delayed germination is not universally advantageous to plants. While some seeds may benefit from delayed germination to ensure favorable environmental conditions for growth and survival, other seeds may have evolved strategies for immediate germination. The advantage of delayed germination depends on the specific ecological context and the species involved.
Statement III states that an impermeable and hard seed coat results in the dormancy of the seed, which is true. A hard and impermeable seed coat can prevent water uptake and gas exchange, thus inhibiting germination. This dormancy mechanism ensures that the seed remains dormant until conditions are favorable for germination, such as sufficient moisture, temperature, or light.
In conclusion, statements I and III are correct regarding seed dormancy. Seed dormancy is controlled by endogenous factors, and an impermeable and hard seed coat can contribute to the dormancy of the seed. However, statement II, suggesting that delayed germination is advantageous to plants, is incorrect.
