Choose the structures that most directly provide nutrients and remove wastes from osteocytes in compact bone.
Ber [7]
I had to look for the missing options of this question and here is my answer:

Osteocyte is the term that describes the cells of the bone. These cells are formed in the mesenchyme. Once the bone matures, the processes then take place inside the Lacunae and the Canaliculi, respectively. Therefore, we can say that the structure that allows the provision of nutrients and removal of wastes from osteocytes would be the canaliculi.

The study has implications for research in community ecology. Can you define some of the key terms in community ecology
Anestetic [448]

Some of the key terms in community ecology are Intraspecific Interaction, interspecific interaction, competitive exclusion, mutualism.

<h3>What is community ecology?</h3>
  • Community ecology aims to provide solutions to these and other community-related concerns.
  • An ecological community is a collection of organisms that coexist or may coexist in a given area. Communities are connected by a shared environment and a web of relationships between the many species.
  • An ever-expanding and comprehensive area of ecology is community ecology. Ecologists look at the variables that affect species distribution, community structure, and biodiversity. Interactions with the abiotic environment and the wide variety of interactions that take place between species are two examples of these elements.
  • The foundation of the majority of community ecology study is species interactions, such as competition, predation, herbivory, parasitism, and mutualism.

Identify how the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes.
kipiarov [429]

The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

<h3>What is the relationship between histones and DNA?</h3>

Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.

<h3>How does DNA compact with histones?</h3>

Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.

Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
