Answer:
- CMB radiation and a very early form of helium were discovered
- Redshift of distant stars and galaxies indicate the universe continues to expand.
Explanation:
After the big bang, the remnants of the explosion are perceived mainly in the microwave spectrum ( after photon decoupling phase) that continues to fade as it diffuses across the expanding universe. As the universe expands, it causes the wavelengths of the photons to increase (relative to the observer who will view the galaxies moving away from him in red-shift).
Answer:
The vegetative cells found in all the kinds of organisms that form the body of an organism are known as somatic cells. They are found in both multicellular and unicellular species. In humans, a somatic cell comprises 46 chromosomes with 23 pairs coming from each parent. However, these cells are non-reproductive.
On the other hand, the gametes refer to the cells that are considered as the reproductive cells of the organism. They are also known as sex cells as they develop into sperm and egg cells. These cells are haploid in nature, and they are formed at the time of meiosis.
True. feces, also known as excrement are the product of excretion.
Viral infection by consuming animal diet is very common these days. These generally cause global pandemic. Most of the pandemic virus are influenza virus, which causes flu like symptoms in humans as well animals including birds, and poultry animals.
The H1N1 virus, which a Influenza A virus causes many type of infections, which includes Swine flu, Cat flu etc. The cat flu is a flu, which is known to be caused by eating cats. The viruses are well known to evolve and mutate easily and cause the changes in the subtype. The mutations in subtypes of viruses makes it difficult to make a vaccine for these types of flu.
Hence, the first blank can be filled with Subtypes, second blank can be filled with Influenza A and the third blank can be filled with Cat Flu.
