A scientist is studying the lysogenic cycle of the lambda 1 phage of Escherichia coli. This means that she is investigating A. the integration and stabilizing of the lambda 1 phase into a host cell's genome.
B. the integration of the bacteria's genome with the viral genome outside of the bacteria's cell wall.
C. the integration of the viral genome into the ribosomes present in the bacteria to direct protein synthesis for the capsid formation.
D. the integration and stabilizing of a virus into its capsid, which provides protection until conditions are better for reproduction.

Answers

Answer 1
Answer:

Answer:

The correct answer is A. the integration and stabilizing of the lambda 1 phase into a host cell's genome.

Explanation:

Viruses have two reproductive cycle i.e, lytic and lysogenic cycle. During the lysogenic cycle, the viral genetic material gets incorporated into the bacterial DNA and gets replicated with the bacterial genome using bacterial molecular machinery.

During the lytic cycle, the viral protein is expressed which forms the progeny phages which release from the cell through cell lysis. Then the new phages infect other cells. Therefore during the lysogenic cycle, integration and stabilization of the viral genome in the host cell's genome occurs. Therefore the right answer is A.

Answers

Answer:

The non-critical factor when a person begin an exercise program is finding friends who like to exercise the same way you do.

Explanation:

Physical exercise is an ideal way to stay healthy. It is a personal activity that should be done in the best way and with a minimum risk. Finding friends who like to exercise can contribute to motivation, but it is not an indispensable element when establishing a personal exercise routine.

Since it is a personal activity that affects an individual's health, personal factors should be considered when establishing a exercise program.

Regarding the other options, which are important factors for the exercise :

  • Use appropriate protective equipment during exercise, allows to avoid injuries during physical activity.
  • See the doctor for a physical assessment prior to beginning exercise, establishing the state of health and physical condition appropriate for this activity.
  • Choose clothing that is designed to match your exercise program,  which must be comfortable and light, allowing maximum performance to be achieved.

What are transgenic organisms? Give one advantage of a transgenic crop.

Answers

Answer:

Transgenic organism:

Transgenic organism may be defined as the organisms whose genetic makeup has been modified by the molecular techniques. These transgenic organism are mainly produced in the laboratory for research work. The genes of one species can be modified or some other gene has been inserted in the organism.

Advantage of transgenic crop.

The transgenic crop has been produced by the genetic alteration of the crop. The main advantage of the transgenic crop is to develop the enhanced quality and quantity of crop. Vitamin rich golden rice has been produced by the transgenic crop.

Explanation:

A 26-year-old woman is in the clinic today for evaluation of weight gain and fatigue. She is 5 feet 6 inches and weighs 175 pounds. Prior to her pregnancy, she weighed 130 pounds and her maximum weight during pregnancy was 155 pounds. She is now 18 months postpartum and continuing to gain weight despite no change in diet or activity. She reports that the fatigue is getting worse even though her daughter is sleeping reliably through the night and the patient feels she is getting plenty of rest. She takes no other medications and has no significant medical history. Her vital signs today are HR 68, BP 108/60, RR 10, temperature 97° F. The nurse practitioner orders a CBC, TSH, and T4.1. What sources of fatigue is the nurse practitioner evaluating with the CBC, T4, and TSH?2. What other history or clinical findings would be indicative of hypothyroidism?3. The patient’s laboratory values show an elevated TSH and a low T4. What does this mean?4. After starting the patient on thyroid hormone replacement, the nurse practitioner asks the patient to return in 8 weeks to check her TSH level. What is the purpose of this test? What should be done if the test result is abnormal?

Answers

Answer:

Studies based on tsh concentrations would indicate whether the thyroid hormones, which are t4 and t3, are in decline or in deficit.

This deficit may be due to a pathology of the thyroid gland and that is why the tsh study is carried out. The TSH hormone is one that stimulates the thyroid gland through the glandular-nervous axis (CNS), if it is in deficit, you want to say that it is being poorly stimulated.

Other findings of hypothyroidism are overweight, decreased basal metabolism, alterations in the cardiovascular system, and increased blood pressure.

That the TSH hormone is elevated, and there is a deficiency of t4, means that the hormone is suffering from some neoplasm, or some pathology that does not collaborate with the function of the gland, that is, that the axis between the central nervous system and The thyroid gland works perfectly, but what is defective is the gland, the body itself captures this deficit of t4 and stimulates the neuronal pathway even more, releasing more TSH, to overstimulate the thyroid gland and that it can generate the amount of t4 required.

The nurse seeks to know that if by administering t4 and balancing the values of this thyroid hormone, TSH normalizes and returns to its normal value, that is, it decreases and does not overstimulate the thyroid gland.

In the event that TSH does not decrease as expected, there will be a double problem to be solved, one at the nervous level and the other at the glandular level.

On the other hand, if the TSH level normalizes, we could understand that the TSH was increased because it wanted to "solve" the t4 deficit.

Explanation:

The thyroid gland works thanks to the stimulation exerted by the central nervous system through TSH.

The TSH hormone is the one that is responsible for stimulating the exact and fair secretion of t4 and t3, sometimes it tends to increase, due to negative feedback, since the increase in t4 and t3 causes the tsh to decrease and the right balance is reached . In case the hormones secreted by the thyroid are in deficit, this will be captured by the body and will not have this negative feedback, therefore the stimulation of the nervous axis will be increased.

The thyroid gland can suffer from metabolism syndromes where hypoactivity or hypothyroidism is detected, or hyperactivity which is also known as hyperthyroidism, although these syndromes are not the only ones, there are also other pathologies such as malignant and benign neoplasms, hashimoto's disease, among others.

Which process do all organisms do when performing cellular respiration?

Answers

Answer:

Glycolysis

Explanation:

Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.

This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.

So, glycolysis is the process that all organisms do during cellular respiration.

Which three layers of the sun make up the suns atmospherea - plasma, corona, convection zone
b - radiative zone, convection zone, core
c - core, convection zone, chromosphere
d - photosphere, chromosphere, corona

Answers

Sun's atmosphere consists photosphere, chromosphere, and corona. Hence option d is correct.

What are the three layers of the suns atmosphere?

Sun is divided into two parts internal sun and atmosphere. In sun's atmosphere, it consists photosphere- the visible surface of the sun,

chromosphere- it is the transition state between the photosphere and corona.

The outermost hot shell of the atmosphere is the corona, these there layers males the sun's atmosphere.

These three layers make the sun's atmosphere apart from its internal structure, core, radiation zone, and convection zone these are three interior layers of the sun.

Therefore option d corona, chromosphere, and photosphere are correct.
