these cells remain in circulation for long periods of time and are ready to respond to a specific antigen should it be encountered again.

Following the Hardy-Weinberg equilibrium theory, the correct options are, A) f(H2H2) = 1.0 – 0.01 – 0.02, D) The population is NOT in Hardy Weinberg equilibrium with respect to the H gene, F) Hardy Weinberg model predicts that F(H1H1) = f(H1)², E) The Hardy Weinberg Equilibrium model predicts that f(H2) = F(H2H2) + 0.5 F(H1H2).

The Hardy-Weinberg equilibrium is a theory that states that a population in equilibrium will express the same allelic and genotypic frequencies through several generations.

Assuming a diallelic gene,

• The frequency of the dominant allele p(X) is p

• The frequency of the recessive allele p(x) is q

The addition of the allelic frequencies equals 1

p + q = 1.  

• p² (Homozygous dominant genotypic frequency),

• 2pq (Heterozygous genotypic frequency),

• q² (Homozygous recessive genotypic frequency).

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium.

In the exposed example,

Genotypic frequencies

F(H1H1) = p² = 2% = 0.02

F(H1H2) = 2pq = 1% = 0.01

F(H2H2) = q² = ?

To get the genotypic frequency of the H2H2 we can clear the following equation,

p² + 2pq + q² = 1

0.02 + 0.01 + q² = 1

q² = 1 - 0.02 - 0.01

q² = 0.97

Now, we can get allelic frequencies,

f(H1) = √p² = √0.02 = 0.14

f(H2) = √q² = √0.97 = 0.98

To see if this population is in H-W equilibrium, the addition of the allelic frequencies should equal 1.

p + q = 1

0.14 + 0.98 ≅ 1

This population is not in H-W equilibrium. It is evolving.

The correct options are

A) f(H2H2) = 1.0 – 0.01 – 0.02

D) The population is NOT in Hardy Weinberg equilibrium with respect to the H gene

F) Hardy Weinberg model predicts that F(H1H1) = f(H1)²

E) The Hardy Weinberg Equilibrium model predicts that f(H2) = F(H2H2) + 0.5 F(H1H2)

To find a 95% confidence interval for the population mean body temperature of healthy females, we can use the theory-based (t-distribution) approach since the sample size is relatively small (n = 67) and the population standard deviation is unknown.

Using the information provided, the mean body temperature for the sample is 98.85 °F, and the standard deviation is 0.852 °F. The formula for the confidence interval is:

Confidence Interval = sample mean ± (t-value * standard error)

First, we need to determine the t-value for a 95% confidence level with (n-1) degrees of freedom. In this case, the degrees of freedom are 67 - 1 = 66. Using a t-table or statistical software, the t-value for a 95% confidence level and 66 degrees of freedom is approximately 1.997.

Next, we calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = standard deviation / √sample size

= 0.852 / √67

≈ 0.104

Now we can calculate the confidence interval:

Confidence Interval = 98.85 ± (1.997 * 0.104)

Simplifying the calculation:

Confidence Interval ≈ 98.85 ± 0.208

Rounding to two decimal places, the 95% confidence interval for the population mean body temperature is approximately (98.64, 99.06) °F.

To determine whether 98.6 °F is a plausible value for the population average body temperature, we need to check if it falls within the confidence interval. In this case, since 98.6 °F is within the confidence interval of (98.64, 99.06) °F, it is a plausible value for the population average body temperature. This means that based on the sample data, there is no strong evidence to suggest that the average body temperature significantly differs from 98.6 °F.

In terms of using the theory-based (t-distribution) approach to find the confidence interval, it is valid in this study because the sample size is small and the population standard deviation is unknown. The t-distribution accounts for the uncertainty introduced by using the sample standard deviation to estimate the population standard deviation.

If two species are close competitors and each is dominant in a different part of the resource, experimental removal of one species is likely to cause the remaining species to expand in ecological (not evolutionary) time. 

Competitive exclusion is the theory behind the interactions between various species, which predicts that two species will not be able to live together when their niches overlap completely. The competitive exclusion theory was proposed by Gause, who hypothesized that when two species compete for the same ecological niche, one will be able to outcompete the other for resources and will eventually drive the other to extinction.

Competitive exclusion is influenced by environmental factors such as biotic interactions, resources, physical parameters like temperature, light, humidity, etc. It is difficult to test this hypothesis with field experiments, but laboratory experiments and observations of natural systems have supported the idea that when two species compete for the same ecological niche, the more efficient competitor will win, eventually resulting in the extinction of the less efficient competitor.

In summary, when two species are close competitors and each is dominant in a different part of the resource, experimental removal of one species is likely to cause the remaining species to expand in ecological (not evolutionary) time.

One advantage of organic farming is that the food is healthier, as there is no pesticide residue on the produce and organic food may contain more antioxidants.

Additionally, organic farming allows for more genetic and species diversity, as crops can be grown without concern for what is climatically suitable to a given area.

The certification process for organic food is also stringent but straightforward, ensuring clear and never misleading labels. However, it is not necessarily true that organic food is less expensive, as there may be subsidies available to organic farmers that get passed on to customers, but this is not always the case.

Finally, while fruits and vegetables grown without pesticides may be blemish-free and have a long shelf life, this is not necessarily an advantage unique to organic farming.

A feature of bovine growth hormone use in the United States is that it cannot be detected in meat or milk of cows receiving it.

This is due to the fact that the hormone is identical to the naturally occurring hormone in cows and therefore cannot be distinguished from it. While some studies have suggested that consuming milk or meat from cows treated with bovine growth hormone could potentially stimulate receptors for human growth hormone, testing has indicated that the risks to human health are minimal. Additionally, the use of bovine growth hormone has been shown to decrease udder infections in cows, leading to a more efficient and profitable dairy industry. However, if consumed from foods, the hormone is denatured by enzymes in the gastrointestinal tract and does not affect human growth or development.

Answer:

If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.

Explanation:

Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.

If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:

ρ = m/V

Therefore, according to the mass and volume of the rock

ρ = 12 grs / 2 cm³

ρ = 6 grs/cm³

Being the density of the rock equal to 6 gr/cm³.

Answer: Mendel considered traits hidden in the first generation to be recessive.

Explanation: Recessive traits, in order to be expressed in an organism's phenotype (physical characteristics) must be homozygous. This means that in a monohybrid cross, which means a trait with only one gene, (E.g. Aa, aa, AA) in order for a recessive gene to be expressed it must be combined with itself. (Examples include aa, bb, cc,)

The sharp increase in water temperature due to global warming drives  zooxanthellae death. Corals lose their symbiotic algae and suffer  bleaching due to the lack of photosynthetic organisms that provide them with color.

Corals are naturally translucid or white organisms. However, they look brightly colored because they host symbionts with colorful photosynthetic pigments.

Corals can host different organisms that live on and among them, giving place to amazing ecosystems.  

The photosynthetic unicellular microalgae zooxanthellae are symbionts to the coral.

This symbiotic relationship allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as tropical clear waters.

When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.

Global warming increases water temperature significantly, which makes the bond between algae and coral break because of algae death. The lack of algae means an increase in coral bleaching since there are no photosynthetic organisms that provide them with color. Besides, the absence of algae means no availability of photosynthetic products.

Complete question:

Although most solutes that enter or exit the cell are relatively small (inorganic ions, sugars, or amino acids), occasionally the movement of larger molecules into or out of the cell is required. For example, certain cells secrete proteins, such as pancreatic cells that secrete insulin. Other cells take up food particles or even entire cells, such as lymphocytes in your immune system. Transport of such large materials into and out of the cytosol cannot be accomplished by transport proteins in the plasma membrane. The transport of large molecules is accomplished by bulk transport via exocytosis and endocytosis. Like other forms of active transport, bulk transport requires an input of energy. Before beginning this tutorial, watch the segment of the Membrane Transport animation on exocytosis and endocytosis. Observe the role that vesicles play in the transport of materials into and out of the cell.

Explanation:

To answer the question, first, we need to know the meaning of endocytosis and exocytosis.

Endocytosis and exocytosis process refers to molecules transport mediated by vesicles. It occurs from and into the cell and needs energy to happen because it is active transport.

Now that we know these concepts, we can sort the phrases into the appropriate bins.

a. decreases the surface area of the plasma membrane. ENDOCYTOSIS, because the new vesicles are formed using the cell membrane

b. requires fusion of vesicles with the plasma membrane. EXOCYTOSIS, because vesicle needs to fuse to the cell membrane to release the carrying material

c. forms vesicles from inward folding of the plasma membrane. ENDOCYTOSIS. Refers to the invagination process of the cell membrane. It only occurs during endocytosis

d. transported substances never physically cross the plasma membrane. BOTH. Substances are too big or too many to be physically transported through the cell membrane

e. increases the surface area of the plasma membrane. EXOCYTOSIS. Occurs when the vesicle fuses the cell membrane to release the content to the exterior.  

f. requires cellular energy. BOTH of them, because they are active transport.

g. secretes large molecules out of the cell. EXOCYTOSIS. The direction is from the interior of the cell to the exterior. These are exportation molecules.

The most appropriate answer to your question would be (c) tens of thousands of kilocalories per day for a person in contemporary England, considering all aspects of energy consumption.

To estimate the daily energy consumption of a person in contemporary England, including food, transportation, household use, and other activities, we can refer to average values. It's important to note that energy consumption can vary depending on various factors such as age, gender, lifestyle, and personal choices. However, I can provide you with a general estimate.

On average, an adult's daily caloric intake from food alone typically ranges from 2,000 to 2,500 kilocalories. This estimate takes into account the energy required for basic bodily functions and physical activity.

However, when considering additional energy consumption from transportation, household use, and other activities, the total energy expenditure would increase. While it is challenging to provide an exact value for these additional energy needs, it is unlikely to reach the level of hundreds of thousands or millions of kilocalories.
