Answer:
Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed.
The correct steps of endochondral ossification is:
- A periosteal bone collar develops.
- spongy bone and the medullary cavity form in the diaphysis.
- The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
- The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
- The spongy bone forms in epiphysis.
<h3>Which bones grow by endochondral ossification?</h3>
Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.
Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.

Answer:
The answer is 25 chromosomes.
Explanation:
The chromosomes of a cell are in the cell core. They convey the hereditary data. Chromosomes are comprised of DNA and protein consolidated as chromatin. Every chromosome contains numerous genes.In the core of every phone, the DNA particle is bundled into string like structures called chromosomes. Every chromosome is comprised of DNA firmly looped ordinarily around proteins considered hi-stones that help its structure
Answer:
a. vitamin d and vitamin b12
Explanation:
Vitamins are groups of organic compounds that are essential in small quantities for healthy human growth, metabolism, development, and body function. Vitamins are found in plants and animal foods or sometimes produced synthetically. Deficiencies of specific vitamins produce specific disorders. Vitamin d and vitamin b12 are important vitamins that the body needs. The body produces vitamin D when the skin is exposed to sunlight and it is very essential for strong bones, while vitamin b12 is naturally present in meats. Deficiency of vitamin d in the body can result in bone problems (including teeth) and it has also been linked to depression. Vitamin b12 deficiency can also affect mental functions by causing disorientation, memory loss, depression and confusion.
From the question, the elderly woman may be developing a deficiency of vitamin d and vitamin b12.
There is two answers to that because there are two different forms of cells that being animal and plant cells. The cell is surrounded by a cell or plasma membrane. Unlike the animal cell the plant cell also has a cell wall surrounding it. This is made of cellulose and is very rigid.
