The chromosomes of offspring are not identical to those of their parents or siblings because ______ is shuffled during meiosis.
tigry1 [53]

The chromosomes of offspring are not identical to those of their parents or siblings because <u>genetic information</u> is shuffled during meiosis.

Meiosis can be described as a cell division process by which gamete cells divide. The number of chromosomes is reduced to half in this cell division process.

During the process of meiosis, genetic information is shuffled between non-sister chromatids of the homologous chromosomes. This shuffling process is referred to as crossing over. A new combination of alleles is formed due to the process of crossing over.

It is due to the process of crossing over that the organisms produced are not identical to each other or the parents. Genetic diversity is important in order for populations to survive which is possible through the process of meiosis.

Proteins around which the long, linear strands of DNA are wrapped; they serve to keep the DNA untangled and to enable an orderly
igor_vitrenko [27]

Answer:

The correct answer is- Histone

Explanation:

DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.

Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.

DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.

The total number of organisms an ecosystem can support is its tolerance range. True or false
Monica [59]

Answer;

The above statement is false

The total number of organisms an ecosystem can support is its carrying capacity.

Explanation;

-Carrying capacity is the average population density or population size of a species below which its numbers tend to increase and above which its numbers tend to decrease because of shortages of resources.

-For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources.

The carrying capacity is different for each species. in a habitat because of that species’ particular food, shelter, and social requirements.

The thoracic cavity contains the ________. It is found ________ to the vertebral cavity.
Natasha_Volkova [10]

Answer: The thoracic cavity contains the heart, lungs and many of the main vessels of the circulatory system. It is found anterior to the vertebral cavity.

Explanation:

The thoracic cavity is the second largest hollow space of the body and it is the space limited by the ribs, the vertebral column, and the sternum. It is the upper region of the body starting from the neck and ending where the diaphragm ends. So, it is separated from the abdominal cavity by the diaphragm. It contains 12 ribs, and 7 of them attach directly to the sternum, 3 attach to the sternum via cartilages and 2 do not attach to the sternum at all and are called floating ribs. The cavity contains several organs, such as the lungs, heart, great vessels and esophagus.

The abdominal cavity spaces around the organs are filled with the core muscles that attach to the posterior spine. Besides. the ribs vertically, horizontally and across the abdominal region.

The vertebral cavity is the posterior portion of the dorsal cavity, it contains the spinal cord within the vertebral column, the meninges and the fluid-filled spaces between them. It is formed by the vertebrae through which the spinal cord passes.

<u>The thoracic cavity is anterior to the vertebral cavity, because anterior describes the front or direction toward the front of the body</u>.
