Answer:
Protists are unicellular eukaryotes which show both plant and animal characters and these are considered as a bridge between plants and animals.
Explanation:
Protists are single-celled life forms and are eukaryotic organisms. Some of the protists like euglena shows both plant and animal characteristics. Protists are important in the following aspects -
- These are a good source of food for many animals. For example phytoplankton is the major source of food for whales. Zooplanktons also serve a good source of food for many aquatic organisms. These organisms often serve as the foundation of the food chain.
- By doing photosynthesis they also used to be beneficial in the balance of ecosystem.
- Some protists are also used as biofuel.
- They often show symbiotic relations with other organisms.
Answer:
The star VY Canis Majoris
It’s not so much that the alleles separate but more so that only one of the parental alleles is passed on. Let’s look at a monohybrid trait to make this easier to comprehend, and let’s say the trait is eye color. One of the parents has blue eyes, a recessive eye color, meaning both of their alleles for that trait are recessive. However, the other parent has brown eyes, a dominant eye color, meaning this parent could either possess one dominant allele that hides the recessive blue (let’s just limit it to two colors to avoid confusion) or they could have two dominant alleles. When gametes are formed, they consist of a combo of alleles, one maternal and one paternal. Meaning, in the case of the heterozygous dominant parent (or the parent with one dominant and one recessive allele) they could either pass on their dominant allele, giving the child brown eyes, or their recessive allele, giving the child blue eyes because they can only ever inherit the recessive trait from the other parent. The law of segregation essentially says that a parent cannot clone itself and create a child in its exact image but rather that the child would inherit one trait from each parent. This is why the child has two alleles for the trait and the parents both have two alleles for this trait. Hope this helps (:
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
