Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day

In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.

Assuming that the population size is N, when

The sigmoid curve represents the logistic growth model.

In the example,

Time period during which Chlorella,

          A) approximates exponential growth ⇒ Between 5 and 10 days

Between 10 and 20 days its already exponential growth.

         B) has reached the carrying capacity of the culture ⇒ 25 to 30 days

Finally,

        C) Growth rate per day for the 5-day period with the greatest growth rate.

First we need to figure out during which period Chlorella experiences the  greatest growth rate. To do it, we just need to make the following substraction,

Growth rate per period = final concentration - initial concentration

Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,

1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day

The answer is 0.27 x 10⁶ cells/mL/day

Explanation:

They need energy to do all these necessary feats.

Answer:

The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.

Explanation:

A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.

Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

The true statements regarding mutations are: Mutations can be the cause of diseases and Mutations are alterations in DNA sequences (Option D, E).

Mutations are defined as changes or alterations in the DNA sequence of a gene or chromosome. They can occur spontaneously or as a result of exposure to certain substances (mutagens) or radiation. Mutations can result in a change in the protein that is made by a gene. The two true statements regarding mutations are Mutations can be the cause of diseases and Mutations are alterations in DNA sequences. Some mutations have little or no effect on protein folding, but others can result in the creation of a non-functional protein or one that does not perform as it should. Mutations that drastically change the protein are unlikely to be beneficial because they can result in the protein losing its function or in a harmful function. Therefore, mutations can cause diseases.

Prokaryotes regulate gene expression at 1. mRNA transcription level.

Prokaryotes largely control mRNA transcription when it comes to controlling gene expression. Prokaryotic gene regulation entails regulating the start of transcription by enhancing or impairing RNA polymerase's affinity for the promoter region of the gene. The binding of transcription factors, presence of activators and repressors, and presence of certain DNA sequences are only a few of the techniques used to achieve this control.

Prokaryotes also have other levels of control of gene expression, including as mRNA translation, mRNA processing, chromatin compaction, and epigenetic inheritance, although these levels are not as important as mRNA transcription in terms of primary regulation. These extra degrees of control over gene expression are more typical of eukaryotic cells.

When there is light, the rod membrane potential will hyperpolarize due to the release of glutamate at the rod-bipolar cell synapse.

In the dark, rods are depolarized and continuously release glutamate onto bipolar cells, inhibiting their activity. When light enters the eye and is absorbed by the rod photoreceptor cells, a cascade of events occurs, leading to the closure of sodium channels and hyperpolarization of the rod membrane. This hyperpolarization reduces the release of glutamate from the rod cells onto bipolar cells.

With decreased glutamate release, bipolar cells become disinhibited and can transmit signals to downstream cells in the visual pathway. Therefore, in the presence of light, the rod membrane potential will hyperpolarize, resulting in a reduction of glutamate release at the rod-bipolar cell synapse.

Beadle and Tatum's work on auxotroph's suggested that metabolism was controlled by protein enzymes by identifying the link between genes and enzymes. This theory is also referred to as "one gene, one enzyme hypothesis" as stated in their experiment.

The experiment was conducted using a bread mold called Neurospora crassa, where they grew the mold on a minimal growth medium that lacked specific nutrients. The scientists observed that certain mutations in the mold led to the inability to grow on this minimal growth medium. They identified the mold that could grow on a medium containing arginine, but failed to grow on a medium that lacked arginine. They then discovered that the mutated molds were deficient in producing specific enzymes required to produce arginine and could only grow on a medium containing arginine.Since the mutants required a specific nutrient that the wild types did not, Beadle and Tatum postulated that the mutations were caused by altered or disrupted genes that affect the enzymes produced by these genes.

Thus, the mutants were unable to produce the required enzymes, which resulted in their inability to grow on the minimal growth medium. Therefore, the experiment concluded that one gene encoded for one enzyme which was responsible for controlling the metabolic pathway of producing arginine. The experiment showed that each gene encoded for a specific enzyme in the metabolic pathway that controlled the production of arginine.

The correct option is (a). The term that best describes the number of calories the body uses at rest is basal metabolic rate (BMR).

The term that best describes the number of calories the body uses at rest is basal metabolic rate (BMR). BMR is the amount of energy that your body requires to maintain basic functions like breathing, circulation, and maintaining body temperature while you are at rest. It's influenced by factors such as age, gender, weight, body composition, and genetics. Basal metabolic rate (BMR) is a measure of how many calories the body uses when at rest. The basal metabolic rate is the minimum number of calories the body requires to sustain its vital functions, including heartbeat, respiration, and maintenance of body temperature, while at rest. This is typically measured while you are awake, but relaxed and in a fasting state. Basal metabolic rate (BMR) refers to the amount of energy that your body requires to maintain basic functions while at rest, and it is influenced by several factors. BMR accounts for around 60-70% of your total daily energy expenditure, which means that it plays a significant role in weight management. For instance, if you have a high BMR, you will burn more calories even when you are not active, which can help you lose weight or maintain a healthy weight. However, if you have a low BMR, you will burn fewer calories even when at rest, which can make it harder to lose weight.To calculate BMR, one needs to take into account their age, gender, weight, height, and body composition. The formula used to calculate BMR is different for men and women.

For instance, for men, the formula is BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years).

For women, the formula is BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years).

Knowing your BMR can help you determine how many calories you need to consume daily to maintain your weight or achieve your weight loss goals.

Answer: D)

polymer

Explanation:

The lagging strand cannot be replicated continuously, and the need for ligase to join the fragments best explains why ligase is necessary for DNA replication. Here option D is the correct answer.

DNA replication is the process by which a cell duplicates its DNA prior to cell division. It involves the synthesis of two new strands of DNA, the leading strand, and the lagging strand. The leading strand is synthesized continuously in the 5' to 3' direction, whereas the lagging strand is synthesized in short fragments called Okazaki fragments.

The lagging strand is synthesized in the opposite direction of DNA unwinding, making it necessary to synthesize it discontinuously. As the replication fork progresses, short Okazaki fragments are synthesized in the 5' to 3' direction away from the replication fork. However, these fragments are not yet connected to form a continuous strand.

This is where ligase comes into play. Ligase is an enzyme that plays a crucial role in DNA replication by catalyzing the joining (ligation) of the Okazaki fragments on the lagging strand. It forms phosphodiester bonds between adjacent nucleotides, sealing the gaps between the fragments and creating a continuous, double-stranded DNA molecule.
