Oh, no... you dropped your study flashcards, and now they're out of order! Put them back into the correct order for a eukaryotic cell. a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine." b. "Unwind the DNA molecule near the promoter." c. "Exit the nucleus to the cytoplasm." d. "Transcribe the complementary RNA strand."

Answer 1
Answer:

Answer:

The correct order would be:

b. "Unwind the DNA molecule near the promoter."

d. "Transcribe the complementary RNA strand."

c. "Exit the nucleus to the cytoplasm."

a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."

The given order is according to the central dogma of a cell. According to central dogma DNA is first transcribed into mRNA which is then moved out of nucleus (in eukaryotic cells).

For transcription, the DNA is unwind near the promoter region where transcription factors and RNA polymerase binds the template strand. It then make mRNA which is moved out of the nucleus.

The mRNA then is translated with the help of ribosome and tRNA. The start codon in mRNA usually codes for methionine due to which tRNA carrying methionine recognises the start codon and initiate the process of translation.

1. Which of the following can be considered fomites: A. Door handle, soap dispenser, a dog infected with rabies virus B. Pencils, a mosquito, unwashed iceberg salad C. Blood pressure cuff, towels, bitten cookies D. All choices are correct 2. An insect that transmits causative agent from infected organism to uninfected one is a/an A. Fomes B. Direct transmitter C. Vector D. Inoculum

Answers

Answer:

1) C. Blood pressure cuff, towels, bitten cookies

2) C. Vector

Explanation:

1) C. Fomities are things that tend to carry infections. Here C is the most plausible answer

2) C. Vector. You often hear this when we talk about diseases that can spread like when mosquitoes spread disease, they act as vector

Final answer:

Fomites are non-living objects that can carry and transmit disease. In your question, the correct answer for fomites would be option C. For the second question, an insect transmitting a disease agent is known as a vector. Option c is the correct answer.

Explanation:

The term fomites refers to inanimate objects that, when contaminated with or exposed to infectious agents (such as bacteria, viruses, fungi), can transfer disease to a new host. Option A. Door handle, soap dispenser, a dog infected with rabies virus is partly correct because while door handles and soap dispensers can be fomites, a dog cannot be as it is a living organism. Similarly, option B. Pencils, a mosquito, unwashed iceberg salad partly fits the definition, but again, a mosquito (a living organism) can't be a fomite, it acts as a vector. Finally, option C. Blood pressure cuff, towels, bitten cookies are all non-living objects and thus can be considered as fomites. This means the answer to your first question isn't D. All choices are correct, but rather it's C. Blood pressure cuff, towels, bitten cookies.

In your second question, an insect that transmits a causative agent from an infected organism to an uninfected one is called a vector. So, the answer is C. Vector.

Which receptors are involved with the proprioception sense?A: stretch receptors in the muscles, tendons and ligaments

B: the macula and otoliths in the vestibule

C: Nociceptors in the muscles and joints

D: The crista ampullaris in the semicircular canals.

Answers

Answer:

A: stretch receptors in the muscles, tendons and ligaments

Explanation:

Proprioception (or kinesthesia) is defined as any postural, positional information transmitted to the central nervous system by stretch receptors in the muscles, tendons and ligaments, joints or skin. In other words, it is the awareness of the movements produced by our members.

These receptors are found within the somatic nervous system, responsible for the different sensory experiences received and interpreted by our body. The most basic function of receptors is to provide the central nervous system (CNS) with information about the internal conditions of organic structures and the external environment.

Convert from kilometers to centimeters to determine the distance from the sun. Use the scale 25,000,000km = 1cm.Mercury- 57.91 million kilometers

Venus - 108.2 million kilometers

Earth - 150 million kilometers

Mars- 227.9 million kilometers

Jupiter- 778.5 million kilometers

Saturn- 1.434 billion kilometers

Uranus- 2.871 billion kilometers

Neptune - 4.495 billion kilometers

Answers

Answer: See Below

Explanation:

25,000,000km = 1cm

In other words 25 million km = 1 cm

Mercury- 57.91 million kilometers

57.91 million km * 1 cm/ 25 million km = 57.91/ 25 cm = 2.3164 cm

Venus - 108.2 million kilometers

108.2 million km * 1 cm/ 25 million km = 108.2 /25 cm =4.328 cm

Earth - 150 million kilometers

150 million km * 1 cm/ 25 million km =150/25 cm = 6 cm

Mars- 227.9 million kilometers

227 .9 million km * 1 cm/ 25 million km = 227.9/25 cm =9.116 cm

Jupiter- 778.5 million kilometers

778.5 km * 1 cm/ 25 million km = 778.5/25 cm =31.14 cm

Saturn- 1.434 billion kilometers

1.434 billion * 1000 million/1 billion = 1434 million

= 1434 million km * 1 cm/ 25 million km =1434/25 cm =57.36 cm

Uranus- 2.871 billion kilometers

2.871 billion * 1000 million/1 billion = 2871 million

2871 million km * 1 cm/ 25 million km =2871/25 cm =114.84 cm

Neptune - 4.495 billion kilometers

4.495 billion * 1000 million/1 billion = 4495million

4495 million km * 1 cm/ 25 million km =4495/25 cm =179.8 cm
