- double membrane
- they have their own DNA
- size similar to prokaryotes
Answer:
A) compact bone
Explanation:
- Compact bone, also known as cortical bone, is the hard, stuff, smoot, white bone tissue sorrounding all bones, it provides structure and support as well as being an storage of minerals. It supports the whole body, protect organs and provides levers for movement.
- Spongy bone, also named cancellous bone, is a highly vascularized kind of bone, it contains red bone marros and is usually located at the ends of long bones. It gives the bone strength and flexibility.
- Irregular bone: from their peculiar form, cannot be grouped as long, short, flat or sesamoid bones, they serve various purposes in the body, such as protection of nervous tissue, affording multiple anchor points, trachea support, and tongue attachment.
- Trabecular bone: also called cancellous bone, is a sponge-like network consisting of myriads of highly interconnected bony trabeculae.

Answer: I assume you meant biologist in this situation. A biologist is a type of scientist that studies living things, their environments, and how they live. Many different types of biologists exist, including research biologists, health care biologists, environmental biologists and biology educators. When it comes to research biologists they study different groups of living organisms around the world. Health care biologists are physicians, veterinarians, nurses and dentists. These types of biologists prevent spreading of infectious and deadly diseases and formulate ways to enhance the health of their patients. Biology educators teach students and up-and-coming biologists basic and sometimes advanced biological sciences in classroom, laboratory and field settings. Environmental biologists study ways to preserve the natural environments of different types of organisms. If you need an example they study animals in captivity and design new methods to help certain species live longer lives in their natural habitats.
Explanation: Hope this helps.
If there are not to many leaves on the trees not too many birds will build a nest in it because the tree is not shaded and the birds will get hot and will not want the small birds to over heat and die.
Answer: May occur in response to growth factors
Explanation:
Hyperplasia is increased cell production in a normal tissue or organ. Hyperplasia may be a sign of abnormal or precancerous changes. This is called pathologic hyperplasia.
Pathologic hyperplasia can occur in response to hormones and growth factors (for example in endometrial hyperplasia, the hyperplasia caused by excessive hormonal stimulation or growth factors acting on target. Thus, patients with hyperplasia of the endometrium are at increased risk for developing endometrial cancer.)
Hyperplasia is also an important response of connective tissue cells in wound healing, in which proliferating fibroblasts and blood vessels aid in repair.
Under normal circumstances, growth factors are responsible for the hyperplasia. Stimulation by growth factors is also involved in the hyperplasia that is associated with certain viral infections, such as papillomaviruses, which cause skin warts and several mucosal lesions composed of masses of hyperplastic epithelium.
Other important concepts to note:
Dysplasia refers to abnormal changes in the size, shape, and organization of mature cells. Compensatory hyperplasia enables organ regeneration and is a normal process: hyperplasia is not normal. Pathologic hyperplasia increases cell number. Hypertrophy is an increase in the size of cells and consequently in the size of the affected organ.
