K-selected species is one that produces few offspring per reproductive event, and the black rhino is one of these.
Because there are fewer Type 1 offspring and they receive more parental care, they have a greater survival rate, which increases the likelihood that they will live to adulthood before passing away.
Type 1 displays a curve where the majority of people die off as they get older. Due to the time and energy required for parental care, which results in their species dying out at an advanced age, this curve depicts the reproductive behavior of K-selected species.
Women started having children later in life as a result of more options for education.
Lengthy gestation durations of many months, slow maturation (and hence prolonged parental care), and long life spans are traits of K-selected species.

Explain to the Econauts why the plants and animals in the biodome were not getting enough energy storage
molecules.
Answers
Answer:
There are different reasons for storing energy. The reason why the plants and animals in the biodome have enough energy storage molecules is because there was not enough carbon in abiotic matter.
Producers are known to create all of the energy storage molecules needed in an ecosystem via photosynthesis. In this process, carbon dioxide is used from abiotic matter.
Ecosystems is known to have different amounts of energy storage molecules. Note that When there is more carbon in abiotic matter, there will be more carbon is available to producers for creating energy storage molecules.
But when there is less carbon in abiotic matter, less carbon is is said to be available for producers creating energy storage molecules.

Answer:
There are several justifications for energy storage. Because there wasn't enough carbon in abiotic matter, the plants and animals in the biodome have ample energy storage molecules.
All of the energy storage molecules required in an ecosystem are known to be produced by producers through photosynthesis. Abiotic matter is employed to produce carbon dioxide in this procedure.
Different ecosystems are known to include varying numbers of energy-storing molecules. Be aware that producers will have access to more carbon when there is more carbon in abiotic matter for the production of energy storage molecules.
Yet, less carbon is believed to be accessible for producers producing energy storage molecules when there is less carbon in abiotic matter.

Select a potted plant from the garden and keep it in a room for five days as shown in the diagram. After five days, you can see that most of the leaves of the plant change yellow. What could be a systematic method to ask right questions? Make a hypothesis or educated guess, conducting scientific experiment and activities about the existing facts to figure out a conclusion in accordance with the scientific learning process.
Answers
Answer:
Explanation:
To systematically investigate the yellowing of the plant's leaves, you can follow these steps:
1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.
2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"
3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.
4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.
5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.
6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.
By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.
Hope it helps!!! :)
A systematic method to ask the right questions, make educated guesses, conduct scientific experiments, and arrive at a conclusion is to follow the scientific method as follows:

Why do the leaves of a potted plant kept away from sunlight turn yellow?The yellowing of leaves in a potted plant kept away from sunlight is primarily due to a process called chlorosis which is the loss or reduction of chlorophyll in plant tissues.
When a potted plant is kept away from sunlight or receives insufficient light, the plant is unable to carry out photosynthesis. Consequently, the chlorophyll content in the leaves decreases, and they start to lose their green color.

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individualsYou can learn more about the Hardy-Weinberg equilibrium at

25% will have the dominant phenotype, and 75% will have the recessive phenotype.
When purebred or homozygous individuals that differ in a particular trait are mated, all offspring will be heterozygous for that trait. If the trait is inherited as dominant and recessive, all F1 offspring exhibit the same phenotype as the parent homozygous for the dominant trait. Monohybrid matings have a dominant to recessive phenotype ratio of 3:1.
In complete dominance, there is no phenotypic difference between AA and Aa individuals. In imperfect dominance, the phenotype of heterozygous individuals is clearly less intense than that of homozygous individuals for the dominant allele, such that the AA and Aa genotypes produce different phenotypes.

10. Briefly describe the process of the hydrolysis reaction for carbohydrates illustrated above:
Answers
The process of dehydration synthesis can explained as Two monosaccharides are brought close together, allowing them to react. A hydroxyl group (-OH) from one monosaccharide and a hydrogen atom (-H) from the other combine to form a molecule of water (H2O). The resulting bond between the two monosaccharides is called a glycosidic bond. The new molecule is a disaccharide, which can be broken down into its constituent monosaccharides by hydrolysis (the addition of water).
Hydrolysis is a chemical reaction that breaks down a compound by adding water molecules. In the case of carbohydrates, hydrolysis involves the breaking of glycosidic bonds, which are the covalent bonds that link sugar molecules together to form larger carbohydrates.
What was the Dehydration synthesis and hydrolysis reaction for carbohydrates?Dehydration synthesis is the process by which carbohydrates are synthesized from monosaccharide units. During this process, a molecule of water is removed from two monosaccharides, which results in the formation of a covalent bond between them, creating a new, larger molecule. This process requires the input of energy in the form of ATP.
During hydrolysis, a water molecule is added to the glycosidic bond, causing it to break and releasing two smaller carbohydrate molecules. One molecule of the carbohydrate will have an oxygen atom and a hydrogen atom added to it from the water, forming an alcohol group (-OH), while the other carbohydrate molecule will have a hydrogen atom and a hydroxyl group (-OH) added to it, forming a carboxylic acid group (-COOH).

Long before the structure of DNA was solved, the physicist Erwin Schrodinger suggested that the three-dimensional arrangement in some polymer had to explain the two main properties of heredity: 1) the stability of life, such that traits were passed faithfully from generation to generation, and 2) the mutability of life, such that traits could change. How did Watson and Crick’s structure explain those two properties?
Answers
Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.
