Answer:
No I do not think that all of the cells in an animal are the same. All of the cells complete different things. For example, Mitochondria cells break down sugars and other compounds into celluar energy, while the skin cells are busy producing Keratin. This shows that no two cells are exactly the same.
Hope this helps!

The discarded theory of blending inheritance most closely resembles incomplete dominance.
<h3>
What is blending inheritance?</h3>
- An antiquated biological notion from the 19th century is the concept of blending inheritance.
- According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
- According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
- As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
- Offspring thus combines the traits of both parents.
- Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
- The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
- Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

Answer:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Explanation:
The fetus can be screened for abnormalities using karyotyping and biochemical analysis using amniocentesis and chorionic villus sample.
<h3>What data can we glean from CVS and amniocentesis?</h3>
In at-risk fetuses, these tests can detect genetic illnesses such cystic fibrosis, Tay-Sachs disease, and sickle cell disease. The main benefit of CVS over amniocentesis is that it is done considerably earlier in pregnancy—at 10 to 13 weeks as opposed to 15 to 20 weeks—thus saving more time for the mother.
<h3>What can a couple learn about their growing fetus from amniocentesis and chorionic villus sampling?</h3>
Amniocentesis and chorionic villus sampling (CVS) are prenatal diagnostic techniques used to identify certain fetal genetic disorders. The likelihood of miscarriage rises with both procedures.
