Answer:
They have some prokaryotic cells though they are being regarded as eukaryotes.
Explanation:
Cells are the basic functional unit of life
Eukaryotic cells have membrane bound nucleus while prokaryotic cells don’t have this.
The body of the tiger consists of different types of cells such as nerve cells, muscle cells, olfactory cells, digestive cells etc. An aggregation of these cells is what makes up the different types of systems ( digestive system, nervous system).
Though animals and human beings are widely regarded as eukaryotic they still possess some cells in the body which are prokaryotic. These prokaryotic cell include cilia which line the respiratory system.
Answer:
A flexible connective tissue, known as cartilage varies from bones in many ways, its microcomposition is less developed in comparison to the bone and is avascular. It is not supplied with nerves and thus depends upon the process of diffusion to attain nutrients. The three kinds of cartilage are fibrous, hyaline, and elastic.
Of these the most widespread kind is the hyaline cartilage, it looks like glass. It is witnessed in embryos, where the formation of bone takes place as hyaline cartilage, which ossifies later. In adults, it is found on the tips of the ribs, on the articular surfaces of the long bones, the parts of the skull, and the rings of the trachea.
Fibrous cartilage is witnessed in the pubic symphysis and intervertebral discs and exhibits many collagen fibers.
Elastic cartilage is witnessed in the internal support of the external ear and the epiglottis and is yellow, springy, and elastic in characteristics.
Answer:
Sequential or integrated screening
Cell-free fetal DNA testing
Proteins in your blood that can mean your baby has a higher risk of birth defects
Explanation:
Sequential or integrated screening
Sequential screening is a test that uses a mix of ultrasound and blood tests to look birth defects at 10 and 13 weeks of pregnancy.
Integrated screening is similar and is done at around 12 weeks and is slightly more accurate
Cell-free fetal DNA testing is testing the baby's DNA that ends up in the mothers blood for signs of birth defects
Here is your answer:
1. Influenza
2. Rhinovirus
3. lentivirus
Reason: Viruses are caused by sickness which could often cause death if not treated or no medication.
<span>I believe the correct answer is D. genetic engineering. So this person wants to have the best qualities of both potatoes and carrots. In order to have that, he needs to take the genetic material of potatoes and that of carrots, mix them, and create something new that will have the characteristics of both of these vegetables. This means that he would be genetically engineering both plants.</span>
