How does the attachment of spindle fibers differ between mitosis and meiosis I?

Answers

in mitosis, the spindle fibers start to divide. in meiosis, these fibers match back up again

In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

WHAT IS MITOSIS AND MEIOSIS?

Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.

WHAT IS SPINDLE FIBER?

Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division).

During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.

However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

Benefits of Biotech in NC
North Carolina is an attractive terrain for biotechnology firms—from 2001 to 2010, the state experienced the highest job growth rate (23.5%) of any of the top biotechnology states in the country. Since 2001, the popularity of NC as a biotech destination has resulted in the creation of more than 12,000 jobs in pharmaceuticals, research, testing and medical labs, agricultural feedstock and chemical industries. All have shown robust growth. Related image
Students in NC have more opportunities to enter the field of biotechnology after graduation than in most states thanks to two very important research centers. The North Carolina Research Center located in Kannapolis and Research Triangle Park near Raleigh, are very important to the NC economy. Both of these facilities bring in tax revenue to our state and offer job opportunities in many science-based fields of study. Image result for research triangle
More than 250 companies and 50,000 people with expertise in fields such as micro-electronics, telecommunications, biotechnology, chemicals, pharmaceuticals, and environmental sciences are located here in NC. Industries invest more than $300 million in Research & Development at the region’s universities each year – double the average R&D investment for innovation clusters elsewhere in the nation. Because of these centers, NC is a leader in biotechnology advances in agriculture, energy and medicine. Our state is home to some of the leading physicians, research scientists, biotechnologists, and agricultural scientists in the US.
Some of the key factors that make North Carolina attractive for the biotechnology industry include:
the presence of the pioneering North Carolina Biotechnology Center and Research Triangle Park have lead to financial incentives the state government has provided to companies such as Merck and Quintiles; and the educational programs developed at both the community college and university level to help firms fill openings with qualified local employees with knowledge and training in biotechnology.
Tax revenues increase because of the large number of developing careers in the field of biotechnology in North Carolina.
Biotechnology affects us in every area of our lives, our food, water, medicine and shelter, improving quality of life. When it comes to Biotechnology, nothing could be finer than to live in North Carolina!

Answers

Answer:

look at Explanation

Explanation:

North Carolina’s biotech industry is quickly expanding.

Within the state, there are more than 600 life science companies employing 61,000 people at an average salary exceeding $81,000 a year – which is nearly twice the state’s overall private sector wage, according to the North Carolina Biotechnology Center.

In total, life science companies and institutions in North Carolina generate $73 billion in economic activity, which is an increase of 23 percent in two years, and account for 228,259 direct and indirect jobs, says North Carolina Biotechnology Center.

Furthermore, while employment in the nation’s life science industry rose by 7.4 percent from 2001 to 2012, North Carolina’s grew at a surprising 31 percent, even with setbacks from the Great Recession of 2008.

Following closely behind California, North Carolina outpaced life science industry growth in other states, including Texas, New York, Massachusetts and Florida, between 2009-2012, according to the U.S. Bureau of Labor Statistics. In the chart below, North Carolina's life science industry grew 5.2% from 2009 to 2012. While California's life sciences industry increased even more at 5.5% during the same time period, other states such as Pennsylvania and New Jersey actually saw their life sciences sectors shrink by 7% and 7.3%, respectively.

Which statement about oogenesis is correct?

A. Diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body.
B. Two diploid secondary oocytes undergo meiosis II to form four haploid ootid cells.
C. Haploid secondary oocytes undergo meiosis I to form a haploid ootid cell and a polar body.
D. Haploid secondary oocytes undergo meiosis II to form a diploid ootid cell.

Answers

A is correct. At the end of meiosis II there are 3 polar bodies and one octet that are all haploid.

The statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.

What is Meiosis?

Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. These daughter cells are genetically unique to the parental cells and are haploid in nature. Germ cells (gamete cells) are typically divided through this mode of cell division.

Oogenesis may be characterized as the process of female gamete formation including the formation of an oocyte from an oogonium followed by meiotic division. During the process of oogenesis, a haploid ootid cell and a polar body are formed with the help of meiotic division.

Therefore, the statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.

In a DNA molecule, the number of adenine bases equals the number
of thymine bases because thymine on one strand bonds to adenine
on the other strand.
True or false

Answers

The answer to the problem is true

It is TRUE that in a DNA molecule, the number of adenine bases equals the number of thymine bases because thymine on one strand bonds to adenine on the other strand.

DNA COMPOSITION:

DNA is composed of nucleotides subunits. There are four nucleotides present in the DNA molecule namely: Adenine, Cytosine, Guanine and Thymine.

Adenine and Thymine hydrogen bond together while Cytosine and Guanine hydrogen bond together i.e. A-T, G-C.

According to Chargaff rule, the amount of adenine bases equals the amount of thymine bases while the amount of guanine bases equals the amount of cytosine bases.

This is because adenine on one strand of DNA bonds to thymine on the other strand of DNA, hence, they must be in the same amount.

High tides on points A & C occur when the moon, the Earth, and the Sun are all lined up.

SUN -----<<<  EARTH >>> ---

( as accurate as it can be in 2D)

As you can see, they are all in a straight line. The gravity of both the moon and the Sun are combined to output the greatest amount of gravitational force as possible; creating high tides on the 2 sides of the Earth. Points A & C represent these two sides and are therefore the answer.
