Genetics combines Dna, technology, and agriculture
Answer:
Las células eucariotas tienen dos funciones primordiales, alimentarse y reproducirse. Las células eucariotas, al igual que las procariotas, llevan a cabo tres funciones esenciales: la nutrición, la relación con el medio y la reproducción. ... Célula con un núcleo definido por una membrana que contiene el material genético.
Explanation:
When two react with two fatty acid molecules a digylceride forms. And when three react with three fatty acid molecules a triglyceride forms. Triglycerides formed <span>between glycerol and unsaturated fatty acids are usually oils. Those </span>formed<span> with saturated acids are usually fats.</span><span />
Answer:
The process that Mildred used is known as Radiocarbon dating
Note: The question is incomplete. The complete question is given below:
Mildred collects a sample of fossilized plant material. She takes it back to her lab to run some tests on it. Mildred is able to measure the amount of carbon-14 in her sample and compare this to the amount of carbon-12 in it. She uses this information to calculate that the fossil is 4,500 year old. The process that Mildred used is known as _______
Radiocarbon dating
Faulting
Indexing
Superposition
Explanation:
Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.
Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.
There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.
<u>Answer</u>: Appear to function in similar ways across diverse groups of organisms.
<u>Explanation</u>:
- The <em>hox</em> genes are a subset of homeotic genes.
- The function of the hox genes is to control the development of the body plan of an individual during the embryonic stage.
- Thus, the basic body form of an organism is laid down with the help of these genes.
- <em>These genes are present in many different species from fruit fly to mice to humans</em>.
- The reason that they are present in different organisms is that there was a common ancestor that possessed the hox gene cluster and then the genes were passed on to different vertebrates. However, the slight changes that have occurred in these genes are due to duplication events.
