Making the following assumption: This would give you a profit of $450, which you could enter into cell i4.

H4 = Donations

G4 =  Streaming Revenues

So, the profit will be:

Enter the following formula in cell I4

=(G4 - H4)

To calculate profit from streaming revenues in cell i4, you would need to subtract any expenses associated with the streaming service from the revenue generated by the service. Here is an example formula you could use:

= Total Streaming Revenues - Cost of Goods Sold - Operating Expenses - Taxes

For example, if your streaming service generated $1,000 in revenue, had $300 in cost of goods sold, $200 in operating expenses, and $50 in taxes, the formula would look like this:

= 1000 - 300 - 200 - 50

This would give you a profit of $450, which you could enter into cell i4.

Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.

In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.

Competition leads to differential survival and reproductive success among individuals.

Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.

These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.

Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.

Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.

Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Answer:

Any offspring with two light color marble

Explanation:

The student can never be able to create an offspring with two light color marble.

The combination of marbles from the mother and father represents the combination the offspring may end up with. The mother and the father contribute one marble each to arrive at the combination of the offspring and in this case, only one light color marble exists between both mother and father. Hence, there is no way an offspring with two light color marble can be produced.

In order to produce an offspring with two light color marbles, both the mother and the father must have, at least, a light color marble in their combinations and each must donate this marble to form the offspring's combination. However, this is not the case as only the mother has one light color marble and the father does not have any.

From the model, a male and a female with one light and one dark marble combination can be produced while offspring with two dark marbles can also be produced.

Explanation:

If a cell with ten chromosomes undergoes meiosis, it will result in the formation of four daughter cells. Meiosis consists of two rounds of division, known as Meiosis I and Meiosis II.

During Meiosis I, the cell undergoes a process called homologous chromosome pairing and crossing over. This results in the separation of homologous pairs of chromosomes, reducing the chromosome number from 10 to 5.

Then, during Meiosis II, each of the daughter cells formed in Meiosis I will undergo a second round of division. In this round, the sister chromatids within each cell separate, resulting in the formation of four haploid daughter cells, each containing five chromosomes.

Therefore, when a cell with ten chromosomes undergoes meiosis, it will produce four daughter cells.

Answer:

If a cell with ten chromosomes undergoes meiosis, it will form four daughter cells.

Explanation:

During meiosis, the cell goes through two rounds of division, resulting in the formation of four haploid daughter cells. In the first round of division, called meiosis I, the cell divides into two daughter cells, each with half the number of chromosomes as the original cell. In this case, each daughter cell would have five chromosomes.

In the second round of division, called meiosis II, each of the two daughter cells from meiosis I divides again, resulting in a total of four haploid daughter cells, each with five chromosomes. So, a cell with ten chromosomes undergoing meiosis would produce four daughter cells, each with five chromosomes.

We have that the Stickleback fish were documented over those 30 years, and along that time, the clarity of the lake's water they were studied was changing over the years.

We have that these species feed upon smaller aquatic organisms, and they're preyed on by biggest fishes, as trouts.

Stickleback, to avoid this, developed a particular structure in their bodies, known as the brownish plates, which over the years began to cover their half body, to cover the whole body.

We have then the following:

1. Clearer water:

Plates covering only half of their body

2. Darker water:

Plates covering almost the whole of their body

To what could we attribute that change in their morphology?

Since the water began to be more obscure than the former, the parts of the body of the fish that were shiny, like the ones not covered by brownish plates, were easier to see for their predators. So the reason these fishes could have developed a whole brownish plate structure could have been the need to be less visible to those trout.

So the occurrences of the different traits changed over the 30-year period because of the pressure that represented the presence of the trout which feed on the stickleback fishes, and also due to the increase in turbidity (water getting less clear) of the water.

Answer:

Mouth: The process of food breakdown first begins in the mouth. The tooth, tongue and jaw apply this process with a mechanical activity. While teeth provide mechanical digestion of food, saliva chemically digests food.

YUtta and esophagus): The tongue pushes the food towards the esophagus. Meanwhile, the trachea is covered with a laryngeal lid. When swallowed food reaches the esophagus, the esophagus contracts peristaltic movements, allowing the food to move towards the stomach.

Stomach: The stomach is an organ that stores food, breaks it down mechanically and secretes enzymes to digest proteins. The secretion of gastric juice is provided by the gastrin hormone. The stomach is an acidic environment. This acid kills bacteria in food and converts proteins into amino acids in enzymes in the stomach. Ultimately, a mixture of partially digested nutrients called chyme is obtained. This mixture is sprayed into the small intestine. Vitamin B12 is a vitamin that is released from the stomach.

Recessive traits are coded by two copies of recessive alleles. The inheritance pattern is autosomal recessive. Yellow pod color and cystic fibrosis are inherited by autosomal recessive genes.

Recessive traits are those coded by recessive alleles and can only be expressed in individuals whose genotyope is homozygous recessive. This is, individuals who only carry recessive alleles for that trait.

Alleles (dominant and recessive) are variants of the same gene.

The gene codes for a characteristic, and the allele codes for one variant of the characteristic, which is the trait.

So recessive traits are coded by the recessive variant of a gene.

Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.

For instance,

The restriction enzymes when combined with the DNA containing restriction sites lead to cuts at those sites yielding restriction fragments. The second statement is correct.

The restriction enzymes are the enzymes that recognize specific sites known as restriction sites. These are enzymes that are found in bacteria and this feature is used as a modern biotechnology tool for genetic editing.

There are two ways the ends are formed after the action of a restriction enzyme. It can form blunt ends or sticky ends. The sticky ends have a region at the end that is single-stranded. This region can then join according to the complementary base pairing with another strand having complementary sticky ends.  

If it is assumed that the RE (restriction) enzyme is not interrupted during the generation of restriction fragments, the resulting restriction fragments would not yield more restriction fragments when re-incubated with the RE enzyme.

A restriction enzyme cuts only at restriction sites forming restriction fragments that do not yield more restriction fragments on subsequent action of the restriction enzyme.

In conclusion, the action of restriction enzymes on DNA gives smaller fragments of DNA. The second option is correct.

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.
