The isotope of an atom containing 31 protons and 39 neutrons suddenly has two neutrons added to it. What isotope is created?

Answers

Answer 1
Answer: The answer is gallium-72. The isotope of an atom containing 31 protons and 39 neutrons suddenly has 2 neutrons added to it. So, it has 31 protons and 41 neutrons (39 + 2 = 41). The mass number of an element is the sum of the number of its protons and neutrons: 31 + 41 = 72. The atomic number of an element is the number of its protons. This isotope has 31 protons and its atomic mass is 31. According to the Periodic table, gallium has atomic mass of 31. Thus the isotope is gallium-72.

These both are prokaryotes, they do not have many membrane bound organelles. Their DNA is found in the nucleoid (no membrane), not the nucleus.

Meiosis i produces _____ cells, each of which is _____.

Answers

The answer is two, haploid. 

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.

Final answer:

Meiosis I produces two cells, both of which are haploid. This means each cell has half the number of chromosomes as the parent cell. This is a crucial step in sexual reproduction, promoting genetic diversity.

Explanation:

Meiosis I produces two cells, each of which is haploid.

During the process of meiosis, a cell initially has two copies of each chromosome, one from the mother and one from the father (46 in humans). This is called a diploid state. However, after meiosis I, it splits into two cells each containing half the number of chromosomes (23 in humans). These cells are said to be haploid because they only possess one copy of each chromosome. The division which occurs during meiosis I is a fundamental part of the sexual reproduction process, as it leads to genetic diversity in offspring.

Glucose can be classified as both of the following terms

Answers

Glucose is a simple sugar that falls within the carbohydrate family. It's classified as a carbohydrate because of its similarity in structure to other carbohydrates and as a monosaccharide, indicating its status as a basic sugar unit. Glucose plays a significant role in providing energy to the body via ATP production.

Glucose can be classified as both a carbohydrate and a monosaccharide. Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms.

They can exist as simple sugars, such as glucose and fructose, as well as complex sugars, like starch and glycogen. The term saccharide is derived from the Greek word for sugar and is often used to denote sugars. Monosaccharide refers to sugars that are the most basic unit like glucose and fructose.

Glucose, specifically, is a simple sugar that serves as a major source of energy for all cells. It's the most readily available form of energy for the body following the digestive process. It's transformed into ATP (Adenosine triphosphate), the main energy currency within a cell, via glycolysis.

Excess glucose is transformed into glycogen and stored in the liver for later usage. The fact that Glucose can be classed as a monosaccharide and carbohydrate stem from its structural properties and its role in providing energy to the body.

Answer:

hope this helps :)

Explanation:

Monosaccharides contain a single unit; disaccharides contain two sugar units; and polysaccharides contain many sugar units as in polymers - most contain glucose as the monosaccharide unit. Number of Carbons: Monosaccharides can be further classified by the number of carbons present.

A viral STD that does not have a cure is _____. (1 point)gonorrhea
syphilis
chlamydia
AIDS

Answers

Answer:

The correct answer is AIDS.

Explanation:

More than thirty distinct bacteria, parasites, and viruses are considered to get transmitted via sexual intercourse. Of these, eight pathogens are associated with the highest occurrence of sexually transmitted disorders. Out of these eight infections, four are presently treatable. These are gonorrhea, syphilis, trichomoniasis, and chlamydia.  

The other four viral infections, which are not treatable are herpes simplex virus, hepatitis B, human papillomavirus, and HIV. However, the signs and symptoms of these diseases because of the untreatable viral infections can be modified or reduced via treatment.  

The viral STD that does not have a cure is AIDS. Therefore, option D is correct.

AIDS (Acquired Immunodeficiency Syndrome) is caused by the human immunodeficiency virus (HIV), which attacks the immune system and weakens its ability to fight off infections and diseases. While there are antiretroviral treatments available to manage HIV infection and slow down the progression to AIDS, there is currently no cure for HIV/AIDS.

Gonorrhea, syphilis, and chlamydia are bacterial STDs, and they can be treated and cured with appropriate antibiotics.
