If a person moved from boston to miami, how would the normal pattern of adh secretion be altered? Could a person prepare to move to a new climate by chemically altering adh release?

Answers

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.

Drugs that raise ADH levels include vasotrict and vasopressin.

Drugs that lower ADH includes alcohol.

Therefore, some chemicals can affect ADH levels in the blood.

A water sample has a pH 10 and contains 56 mg/L HCO3- and 32 mg/L CO32-. Calculate the alkalinity in mg/L as CaCO3.

Answers

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

What is alkalinity?

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}

Molar mass of HCO3- = 61g/molMolar mass of CO3 = 60g/molMolar mass of CaCO3 = 100g/mol

Eq. cot. of HCO3- = 61g/EqEq. cot. of CO3 = 30g/EqEq. cot. of CaCO3 = 50g/Eq

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

In this case, we have to The alkalinity as CaCO3 in mg/L is 108,23 mg/L

Cross one parent that is heterozygous for both beak color and feather color with a parent that is homozygous for both recessive traits. What are the genotypes of the parents

Answers

Heterozygous for both traits genotype = BbFf

Homozygous for both traits genotype = bfbf

What are homozygous and heterozygous traits?

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

Answers

Such lethal allele combinations appear to alter Mendelian ratios because homozygotes for the lethal allele do not appear as a progeny class.

What are Mendel’s laws of inheritance?Mendel proposed the law of inheritance of traits from the first generation to the next generation. Law of inheritance is made up of three laws: Law of segregation, law of independent assortment and law of dominance.The law of dominance states that recessive traits are always dominated or masked by dominant trait.Lethal alleles are alleles that cause an organism to die only when present in a homozygous condition. In case of lethal genes, only the heterozygous is able to survive in the progeny but they cause death if an organism carries two copies of the lethal allele. As a result homozygotes for the lethal allele do not appear as a progeny class.Lethal alleles can cause death of an organism prenatally or any time after birth, though they commonly manifest early in development.

Stubble bristles (Sb) is dominant to wildtype bristles (Sb ) in Drosophila melanogaster. In a population where there are 137 flies with wildtype bristles and 836 flies with stubble bristles, what are the allele frequencies for the Sb and Sb alleles (assuming the population is in Hardy-Weinberg equilibrium)

Answers

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

What is Hardy-Weinberg Equilibrium?

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

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.

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.

The higher the rate of photosynthesis, the lower the respiratory rate?

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.

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.

b. engulf many different pathogens.
c. present foreign antigens that stimulate adaptive immune responses.
d. produce multiple antibodies.

Answers

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.

The smooth but steady increase in muscular tension that is produced by increasing the number of active motor units is called __________.

Answers

The smooth, but steady, increase in muscular tension produced by increasing the number of active motor units is called a recruitment.

Muscle tension is the force produced when a muscle contracts (or when sarcomeres shorten). The two primary forms of skeletal muscle contractions, isotonic contractions and isometric contractions, are produced when a muscle contracts against a load that is not moving.

A load is transported as the length of the muscle varies during isotonic contractions, in which the tension in the muscle remains constant (shortens). Concentric and eccentric contractions are the two varieties of isotonic contractions. When a muscle contracts isometrically, the angle of a skeletal joint remains the same while tension is produced in the muscle. Sarcomeres shorten and muscles tense up during isometric contractions, but the load is not moved since the force generated is insufficient to overcome the resistance provided by the load.
