Give reason. Mosquitoes and housefly are placed in the phylum arthropoda​

Answers

Answer 1

Mosquitoes and Housefly are grouped under the phylum Arthropoda because they both posses jointed legs (or appendages).

Animals that have jointed appendages are called Arthropods (i.e animals with jointed legs). They are triploblastic (i.e they have 3 germ layers) and exhibit bilateral symmetry. They are both six-legged arthropods sub-grouped under the class Hexapoda (coined from the word "hexa" meaning six and "Poda" meaning leg). Their body are divided into three parts; head, thorax and abdomen.

Answer:

In relative dating, fossils are dated according to the depth at which they were buried While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils.

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms

Answers

Answer:

Protozoa

Explanation:

The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.

Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.

Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.

Hence, the case of Mr. L would be that of protozoa.

For each of the following structures, first indicate its function in the fetus; then, note its fate (what happens to it or what it is converted to after birth).

a. Umbilical artery
b. Umbilical vein
c. Ductus venosus
d. Ductus arterious
e. Foramen ovale

Answers

Answer:

1. Functions:

a. Umbilical artery >> carries deoxygenated blood from the fetus to the placenta

b. Umbilical vein >> transports oxygenated blood from the placenta to the fetus

c. Ductus venosus >> allows oxygenated blood from the placenta to bypass the liver

d. Ductus arterious >> allows most of the blood from the right ventricle to bypass the fetus's non-functioning lungs

e. Foramen ovale >> oxygenated blood from the umbilical vein to bypass the pulmonary circulation

2. After the bird:

1. Umbilical artery >> medial umbilical ligament

2. Umbilical vein >> round ligament of the liver

3. Ductus venosus  >> ligamentum venosum

4. Ductus arteriosus >> ligamentum arteriosum

5. Foramen ovale >> fossa ovalis

Explanation:

The umbilical artery is a paired artery localized in the abdominal and pelvic regions, which carries deoxygenated blood from the fetus to the placenta through the umbilical cord. The medial umbilical ligament is the obliterated part of the umbilical artery that arises from the internal iliac arteries. In utero, the umbilical arteries carry waste products back to the placenta, whereas the umbilical vein carries oxygenated blood from the placenta to the fetus. The round ligament of the liver (also known as ligamentum teres hepatis) is a remnant of the umbilical vein that  exists in the embryonic stage, it connects the left lobe of the liver to the umbilicus. The ductus venosus is a slender shunt that allows oxygenated blood from the placenta to bypass the liver, it connects the intra-hepatic portion of the umbilical vein to the inferior vena cava. The ligamentum venosum is an extrahepatic, slender, and fibrous remnant of the fetal ductus venosus that travels between the left portal vein and the inferior vena cava. The ductus arteriosus is a fetal artery that connects the aorta to the pulmonary artery. The ligamentum arteriosum is a nonfunctional vestige of the ductus arteriosus, it is attached to the superior surface of the pulmonary trunk. The foramen ovale is an oval-shaped, small, opening in the wall (septum) between the two upper chambers of the heart. The fossa ovalis is a vestige stricture of the foramen ovale of the embryonic heart, which forms a depression in the right atrium of the heart.

The second generation of purebred cross of -hom-ozygo us recessive organism, with a —hom-ozygous dominant organism, contain a ratio of approximately _______ expressed dominant traits to recessive traits.
A. 2:1
B. 1:1
C. 1:3
D. 3:1

Answers

Answer:

D. 3:1

Explanation:

Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.

However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

As you read in this chapter, fungi have long formed symbiotic associations with plants and with algae. How may these two types of associations lead to emergent properties in biological communities

Answers

Answer:

Fungi show symbiotic association with algae and plants. With plants, they thrive as endophytes in a form of the symbiotic association. This symbiotic association results in the emergence of novel characteristics in the world of biology.  

The lichens function as a tool in finding the quality of air, as they grow in the environment containing good air quality. The tolerance towards heat is another characteristic. Some of the endophytes are witnessed in the plants, which grow in very hot conditions.  

At such conditions, no fungi or plant can thrive, however, in the symbiotic association, they possess the tendency to thrive. If one tries to separate them, it results in the death of both.

What are the mechanism that use to resist the antimicrobial agents?

There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.

These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.

There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.

15. Assuming the fluorescence threshold is set to be 1. Which gene has the highest gene expression rate? What is the Ct value? Gene with highest expression = ______________ Ct value = _______________

Answers

Answer:

The correct answer is - Gene 1 and 14.5 (or 14).

Explanation:

The cycle threshold is denoted as Ct value. It is the cross point at the threshold line meets with fluorescence signal reaction curve. In the given RTpcr experiment, the threshold line is fluorescence intensity 1 thus, Ct value for each gene will be the point at which each curve meets the fluorescence intensity line at 1. Ct value of is inversely proportional to amount of nucleic acid in the given sample.

Here, the Ct for gene 1 is the lowest, so the amount of DNA would be highest.

The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna

For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed

QUESTION 1

According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.

According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:

3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)
