Maarit and her Maya ancestor's civilizations grew potatoes, corn, beans, squash and chilies as part of their routine.

Different types of plants evolved in America and were selected by native civilizations, which include, among others,  potatoes, corn, beans, squash and chilies.

Conventional breeding techniques were used by native civilizations such as Maya civilization in order to produce new crops, including maize, which is an extensive crop plant that shows genetic heterosis (it is an allogamous plant).

In conclusion, Maarit and her Maya ancestor's civilizations grew potatoes, corn, beans, squash and chilies as part of their routine.

Generation after generation, populations in H-W equilibrium have the same allelic and genotypic frequencies.

f(Sb) = p = 0.626. f(Sb+) = q = 0.374. F(SbSb+) = 2pq = 0.468

According to the Hardy-Weinberg equilibrium theory, assuming a diallelic gene.

The dominant allele p(X) has a frequency of p.

The recessive allele p(x) has a frequency of q.

After one generation, the genotypic frequencies are

p² (Homozygous dominant genotypic frequency),

2pq (Heterozygous genotypic frequency),

q² (Homozygous recessive genotypic frequency).

In a population that is in H-W equilibrium, genotypic and allelic frequencies don't change over generations.

The allelic frequencies added together equal 1.

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed:

Sb is dominant

Sb+ is recessive ⇒ wild type

Population size ⇒ 137 + 836 = 973

wildtype bristles ⇒ 137  ⇒ Sb + Sb+

stubble bristles ⇒ 836 ⇒ SbSb and SbSb+

Phenotypic frequency:

F(wildtype) = q² = 137/973 = 0.14

F(stubble) = p² + 2pq = 836/973 = 0.86

To determine the genotypic and allelic frequencies, we will now use the frequency of the recessive trait.

F(Sb+Sb+) = q² = 137/973 = 0.14 ⇒ Recessive Genotypic frequency

f(Sb+) = q = √0.14 = 0.374 ⇒ Recessive Allelic frequency

We will now utilize q (recessive allelic frequency) to determine the dominant genotypic frequency and the dominant allelic frequency since this population is in H-W equilibrium. We will solve the following equation to achieve this.

p + q = 1

p + 0.374 = 1

p = 1 - 0.374

p = 0.626 ⇒ Dominant Allelic frequency

F( SbSb) = p² = 0.626² = 0.392 ⇒ Dominant Genotypic frequency

The heterozygous frequency will be the last thing we learn. There are 2 possibilities, The dominant genotypic frequency is subtracted from the dominant phenotypic frequency.

F(SbSb + SbSb+) - F(SbSb) = 0.86 - 0.392 = 0.468

p² + 2pq + q² = 1

0.392 + 2pq + 0.14 = 1

2pq = 1 - 0.392 - 0.14

2pq = 0.468

Answers:

- f(Sb) = p = 0.626 ⇒ Dominant Allelic frequency

- f(Sb+) = q = 0.374 ⇒ Recessive Allelic frequency

- F(SbSb+) = 2pq = 0.468 ⇒ Heterozygous frequency

Phagocytic cells are an important part of the innate immune system because of their ability to engulf many different pathogens. So the correct answer is b. engulf many different pathogens.

The detection of a microbial invasion is typically swiftly followed by its engulfment by a phagocytic cell in all animals, including invertebrates and vertebrates. In the tissues across the body of vertebrates, macrophages are particularly prevalent in the lungs and stomach, two places where infections are most prone. Additionally, the liver, spleen, and connective tissues contain significant amounts. These long-lasting cells are among the first to come into contact with invasive pathogens and patrol the body's tissues.

Neutrophils, the second-largest family of phagocytic cells in vertebrates, are short-lived cells prevalent in blood but absent from healthy, normal tissues.

The publication about the effect of orthodontic forces on cytokine and receptor levels in gingival fluid investigates how this treatment can increase inflammation.

Cytokines are molecules of the immune system that act during different types of immune responses, especially in inflammatory pathways.

Cytokines are mainly secreted by helper T immune cells (T cells) and macrophages.

In this case, the publication above mentioned uses different cytokine biomarkers to test inflammatory responses after orthodontic treatment (e.g., IL-1β, TNF-α, IL-8, etc).

The correct option is (c) LDL consists of cholesterol and protein.

One of the five main categories of lipoproteins, low-density lipoprotein (LDL), transports cholesterol throughout the body to the areas where it is required for cell repair and deposits it inside the artery walls. They need to be bound to proteins in order to pass through the hydrophilic blood.

The hydrophobic core of the LDL particle is made up of fatty acid esters of cholesterol, while the outer membrane is made up of unesterified cholesterol. The membrane contains a single copy of the hydrophobic apo-B protein, which facilitates the binding of LDL particles to particular cell-surface receptors.

Hence,  LDL consists of cholesterol and protein.

Answer:

A.) hormones

Explanation:

Neurons are to the nervous system as hormones are to the endocrine system.

The endocrine system regulates all of our bodily processes via the feedback of hormones.

The peripheral nervous system receives information from the environment and relays commands from the central nervous system to organs and glands.

The nerves that emerge from the brain and spinal cord make up the peripheral nervous system. The CNS and the body components are connected through a network of nerves. The somatic nervous system and the autonomic nervous system are additional divisions of the peripheral nervous system.

The somatic nervous system and the autonomic nervous system are two subsystems of the peripheral nervous system. With the exception of the optic nerve (cranial nerve II) and the retina, the cranial nerves make up the PNS in the somatic nervous system. The second cranial nerve is a tract of the diencephalon and not a real peripheral nerve.  The CNS is where the cranial nerve ganglia were born. The PNS, however, is thought to include the ten remaining cranial nerve axons because they travel outside of the brain.  Smooth muscle and glands are subject to involuntary control by the autonomic nervous system.  The sympathetic and parasympathetic states of the system are made possible by the relationship between the central nervous system and the organs.

The alkalinity as CaCO3 in mg/L is 108,23

Alkalinity is the total measure of substances present in water, capable of neutralizing acids. In other words, it is the amount of substances present in the water that act as a buffer.

With that being said;

Equivalent weight = {molar mass}*{ion charge/oxidation number}

Alkalinity due to CO3 = {32x50}{30} = 53.33mg/L

Alkalinity due to HCO3- = {56x50}{61} = 54,90mg/L

Total Alkalinity = 53,33 + 54,90 = 108,23 mg/L

Heterozygous for both traits genotype = BbFf

Homozygous for both traits genotype = bfbf

The term "identical genes received during the zygote period of development" is homozygous. The parents of a person with homozygous features gave them one copy of each allele. Both dominant and recessive alleles are possible.

Children with heterozygous traits inherit a dominant gene from one parent and a recessive allele from the other parent.

Let the alleles for beak color be:

Dominant allele = B

Recessive allele = b

Let the alleles for feather color be:

Dominant allele = F

Recessive allele = f

Therefore,

Parent 1 with heterozygous traits will have genotype = BbFf

(because it is heterozygous for both the traits)

Parent 2 with homozygous traits will have genotype = bfbf

In a plant, when the rate of respiration is less than the rate of photosynthesis, the volume of carbon dioxide that is released It increases.

At points where the rate of photosynthesis exceeds the rate of the cell battery, the cell is releasing more O2 than it is consuming. There is also a point where the rate of photosynthesis and the rate of cellular respiration equal each other, called the photic compensation point.

Therefore, oxygen released by photosynthesis is consumed in cellular respiration, and CO2 released in cellular respiration is consumed in photosynthesis. Therefore, gas exchange between the plant and the environment is null.

Boston is colder than Miami.

Therefore, more water is lost in the form of sweat in summer than in winter. In the summer, your body becomes dehydrated, releasing more ADH in your body.

ADH Syndrome of antidiuretic hormone or vasopressin is synthesized by the hypothalamus and released from the posterior pituitary gland to maintain blood osmolality. It increases the reabsorption of water from the kidney nephrons.

Therefore, in a cold environment like Boston, ADH will be low and will increase significantly in Miami.

Several chemicals change ADH levels.
