Fungi are a kind of decomposers.
If there were no fungi, the ecosystem would not exist, and dead organisms would also pile up because there were no decomposers any more.
Answer:
Answer
take a plant having partially green and white leaves.
Destarch the plant leaves by placing the plant in dark room for three days.
The potted plant then placed in the exposure of sunlight for three days.
pluck the leaf of the plant and allow to boil it in alcohol to remove its green colour.
Answer:
fewer in number.
Explanation:
A low sperm count also known as oligospermia can be defined as a medical condition which typically involves a man (adult male) having fewer than 15 million sperm per millilitre of semen.
Basically, low sperm count (oligospermia) is usually caused in men due to health and lifestyle factors such as smoking, alcohol or drug abuse, obesity, genetics, sexually transmitted infections (STIs), age etc.
Hence, smokers, alcohol abusers, overweight and obesity men are more likely to have sperm which are fewer in number i.e fewer than 15 million sperm per millilitre of semen.
Generally, a healthy or normal sperm motility ranges from over 20 million to 200 million sperm per millilitre of semen.
Answer:
mRNA: 3' AUG-AAU-GCU-GCC-GGU-GA-5'
amino acids : methionine, asparagine, alanine, arginine, proline
type of mutation: deletion, missense
Explanation:
The mRNA sequence is complementary to the DNA sequence. A always pairs with T, C always pairs with G. Except this is an RNA sequence not a DNA sequence, so T is replaced with U.
The mRNA sequence is translated into an amino acid sequence based on the triplet code. The triplet code for this sequence is shown in the attached picture. Each triplet signifies a specific amino acid. The codon can be identified from the table and placed in sequence. We can see that the new DNA strand has caused a new amino acid sequence. It has also left us with an incomplete sequence, as GA cannot signify an amino acid.
The type of mutation is a single base deletion. We can see that the base C is missing from the 9th amino acid in the original strand. As you can see, this has an ongoing affect on all the bases in the rest of the sequence, as it changes the way the sequence is organised into codons. This results in a missense mutation.
Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
