Answer:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Explanation:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave. - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait. - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different.
- this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring. - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
Besides wildfires, human settlements affect neighboring ecosystems through biotic processes, including exotic species introduction, wildlife subsidization, disease transfer, landcover conversion, fragmentation, and habitat loss.
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged. Hope I helped! ^^

有糸分裂は、親細胞と遺伝的に同じであるより多くの細胞を作る方法です。それは胚の発達において重要な役割を果たしており、私たちの体の成長と発達にとっても重要です。有糸分裂は新しい細胞を生成し、古い、失われた、または損傷した細胞を置き換えます。私が助けてくれたらいいのに！ ^^
Answer:
Osteon
Explanation:
Bone tissue may be of two types; compact bone tissue that form the outer hard covering of bones and spongy bone tissue that form inner soft portion of bone. Osteon are found in compact bone.
Osteons are cylindrical structures composed from clustre of Osteocytes and layers of extracellular matrix around a central canal connected by canaliculi for the transportation of blood. The haversian canal is surrounded by lamella that comprises the osteon. Osteons run parallel to long axis of bones and present in bones of many mammals, reptiles and birds. In some bones the stress or pressure in applied from few directions and osteons are aligned in that direction so they provide protection from bone bending or fracturing from compressive forces.
