Well, there is only one realistic answer. Option One is when you take the DNA of two different people or creatures and combine them into one organism. Cloning wouldn't prove anything here, "hybridization" is weird - but it doesn't have anything to do with the situation. So only only remaining option is DNA Profiling - also known as DNA Mapping, which shows the DNA structure and order that can be seen the same way in siblings (slightly different of course but it is still the right answer).
Answer:
The correct answer is option 3. "secondary structure".
Explanation:
The secondary structure of polypeptide and proteins refers to the second order of folding, including common structures such as beta sheets, alpha helix, as well as turns and loops. The hydrogen bonds between the oxygen and nitrogen atoms of the peptide bonds are crucial to secondary structures, as these hydrogen bonds form and stabilize the aforementioned common structures.
Answer: (1) It has a tail to travel to the egg (2) contains a nucleus in the head which will fertilise the egg
Explanation: Firstly it has a tail to help it travel to the egg. Secondly it contains the nucleus in the head that will fertilise the egg. Thirdly the acrosome contains enzymes in order for the sperm to penetrate the egg. Finally, the sperm cell is packed with mitochondria to provide the energy needed to reach the egg.
Plant types matched with their descriptions
- Hydrophytes - Aquatic plants
- Mesophytes - Plants with habitats that are neither too wet nor too dry
- Xerophytes - Plants with very dry habitats
Hydrophytes are aquatic plants that may be free floating, fully submerged or partly submerged (amphibious) in water. The vascular tissue of hydrophytes is very poorly developed. Examples of hydrophytes are Ottelia, Sagittaria and Utricularia.
Mesophytes are plants that live in habitats that have a moderate supply of water (neither too wet nor too dry. Mesophytes are usually large, fast growing, and have well developed roots and leaves. Examples of mesophytes are clover and maize (corn).
Xerophytes are plants that are able to thrive with very dry habitats where the available soil water is low. Examples of xerophytes are Acacia and Carthamus.
Answer:
Several ways really.
Explanation:
It has changed how the government views laws to do with abortion, put in new laws to do with how we can change ourselves or our children, etc. etc. There are a lot more to do with the laws behind it, but the government has also been researching how to use genetics in the army and things like that.
I hope this can give you a start on it!
