If population size temporarily exceeds the environmental _______, deaths will increase until the population size returns to previous levels.A. carrying capacity
B. density
C. growth factor
D. reclamation

Answers

Correct answer: A). Carrying capacity

The carrying capacity of an environment is the maximum population size of the species an environment can be able to sustain indefinitely, There would be no lack of food, water, habitat and other necessities in the environment.

It is necessary that the environment supports the given species with the natural resource limits, it should degrade the natural, social and the cultural environment. No population can live beyond the environment's carrying capacity.

the answer is A) carrying capacity

Which of these can be found in both gymnosperms and angiosperms?A)vascular tissue and flowers
B)vascular tissue and seeds
C)flowers and vascular tissue
D)enclosed seeds and flowers

Answers

Regarding what can be found in both gymnosperms and angiosperms, the correct choice is B)vascular tissue and seeds. Both gymnosperms and angiosperms have vascular tissue that is specialized for transport of minerals, water, and organic compounds. Also, both gymnosperms and angiosperms have seeds. The only difference is that angiosperms have seeds hidden in the ovary while gymnosperms have seed on the surface of the scales of the cones.

Answer:

b - vascular tissue and seeds

Explanation:

What can cause changes in DNA sequences

Answers

Ans. Mutation.

Mutations are defined as permanent changes in the nucleotide sequence of DNA molecules that transmit from generations to generations.

These mutations may arise naturally (during DNA replication) or due to the exposure to mutation-causing agents (mutagens), such as UV-rays, ethidium bromide, and free radicals.

Thus, the correct answer is 'mutations.

I need help writing a 5+ sentence summary about this passage!!!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 imageStudents 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 triangleMore 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!
