carbon compound that stores and transmits genetic information

Basic natural selection:

1. One population of the same species is cut into 2 or more groups. Maybe by a landslide. Migration, anything.

2. The species cut off from the main population experiences environments they've never seen before.

3. Many of the separated species die. Leaving the strongest and the ones with the most favourable features, such as thick fur if if its cold, to live and reproduce. Passing on their genes to their offspring and eventually creates a new population with these features.

4. Eventually, the variation in the new population caused by mutations in genes, become so different to the main population. They cannot interbreed anymore and thus makes them a different species.

Answer: Felipe is wrong.

Explanation:

In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.

Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)

When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.

This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.

Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.

We can come to this answer because:

Therefore, it will not be possible to see the moon, as Felipe said.

When lactose is not present in the lactose, E. coli undergoes a specific response to adapt to this change. In this situation, the genes that produce the enzymes needed to break down lactose are not expressed. This means that the E. coli cells will not produce the enzymes necessary for metabolizing lactose, allowing them to conserve energy and resources.

The process occurs through a regulatory mechanism called the lac operon. The lac operon is a set of genes responsible for the production of enzymes involved in lactose metabolism, such as beta-galactosidase, permease, and transacetylase. When lactose is absent, a protein called the lac repressor binds to the operator region of the lac operon, preventing the expression of these genes.
The lac repressor is sensitive to the presence of lactose in the environment. When lactose is available, it binds to the lac repressor, causing a conformational change in the protein structure. This change in the lac repressor makes it unable to bind to the operator region, allowing the transcription of the genes in the lac operon and subsequent production of enzymes needed for lactose breakdown.
In summary, when lactose is not present, E. coli cells do not express the genes that produce the needed to break down lactose. Instead, the lac repressor protein prevents their expression, allowing the cells to conserve energy and resources. It is essential to note that E. coli can survive without lactose, as it can metabolize other sugars and nutrients available in its environment.

Explanation:

The correct option for the answer is: 2. Inbreeding increases the frequency of homozygotes, which are always less fit than heterozygotes.

Inbreeding increases the chances of mating between individuals that share common alleles, leading to offspring that are more likely to be homozygous. Homozygosity refers to having the same alleles at a specific gene locus, while heterozygosity refers to having different alleles. Homozygotes, having two identical alleles, can be less fit than heterozygotes, which have greater genetic diversity. This reduced fitness in homozygotes is often due to the expression of detrimental or deleterious traits.

Inbreeding depression decreases a population's fitness through the following mechanisms:

Inbreeding can directly increase the frequency of harmful recessive alleles, fixing them in the population. When individuals that are closely related mate, there is an increased chance of inheriting the same harmful recessive alleles from both parents. As a result, these harmful alleles become more prevalent in the population, leading to decreased fitness due to the expression of detrimental traits.

Inbreeding increases the frequency of homozygotes, which are always less fit than heterozygotes. Heterozygosity refers to having different alleles at a specific gene locus, while homozygosity means having the same alleles. Inbreeding increases the chances of mating between individuals that share common alleles, resulting in offspring that are more likely to be homozygous. Homozygosity for certain genes can lead to reduced fitness due to the expression of deleterious traits.

Inbreeding can increase the frequency of homozygotes for harmful recessive alleles. When individuals with common ancestry reproduce, there is a higher likelihood of offspring inheriting harmful recessive alleles from both parents. This increased frequency of homozygotes for detrimental alleles can manifest in reduced fitness and increased susceptibility to diseases or other detrimental effects.

Inbreeding does not typically increase the frequency of heterozygotes. Instead, it reduces genetic diversity within the population, which can result in the loss of advantageous genetic variations. In some cases, heterozygotes may possess advantageous traits due to the presence of different alleles. Inbreeding can reduce the occurrence of such heterozygotes, potentially leading to decreased fitness.

When both the CNO cycle and the proton-proton chain combine 4 H nuclei to produce 1 He nucleus, these two processes do not release the same amount of energy per He nucleus produced.

This is because the CNO cycle releases more energy per He nucleus produced as compared to the proton-proton chain. The proton-proton chain is one of the two fusion reactions that take place in the Sun. It is a sequence of nuclear reactions that combine hydrogen into helium.

It is also the process that powers other main-sequence stars. The CNO cycle is a fusion reaction that occurs in stars. It is an alternative way of fusing hydrogen into helium. It is most prevalent in stars that are larger and hotter than the Sun. The CNO cycle accounts for roughly 1% of the energy generated by the Sun.

The amount of energy released by each of the reactions in the proton-proton chain and the CNO cycle is different. As compared to the proton-proton chain, the CNO cycle is more efficient at producing energy. This is because the CNO cycle uses carbon, nitrogen, and oxygen as catalysts. Therefore, the CNO cycle is responsible for most of the energy generated by massive stars.

The haploid number of chromosomes for an organism with a diploid number of chromosomes of 52 is 26.

The haploid cell is a cell that contains a single set of chromosomes, whereas the diploid cell is a cell that contains two sets of chromosomes. Each parent contributes one set of chromosomes in diploid cells. In diploid cells, one set of chromosomes is derived from each parent. A haploid cell, on the other hand, contains only one set of chromosomes. When a haploid cell from the father combines with a haploid cell from the mother during fertilization, a diploid cell is formed.

The formation of gametes is a significant role in haploid cells, while the formation of somatic cells is a significant role in diploid cells. Gametes, such as egg and sperm cells, are formed as a result of meiosis in diploid cells. The haploid cells combine during fertilization to form a zygote. The zygote, in turn, develops into a diploid cell.

The haploid number of chromosomes, abbreviated n, is the number of chromosomes in a gamete cell. A haploid number of chromosomes varies from one organism to another. For example, the haploid number of chromosomes in humans is 23. In contrast, the diploid number of chromosomes in humans is 46. In humans, a haploid sperm cell and a haploid egg cell combine to form a diploid zygote during fertilization.

Therefore, the haploid number of chromosomes for an organism with a diploid number of chromosomes of 52 is 26. Each of the organism's gametes will contain 26 chromosomes, which will combine during fertilization to form a diploid zygote with 52 chromosomes.

Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.

To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.

Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.

Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.

It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.
