The correct answer is - B. Beak size determines what the bird can eat.
The beak of a bird can come in many different shapes and sizes. It can be pointy, long, short, rounded, scythe-like, thin, thick... All of those shapes and sizes have a specific role, and that role is to enable the bird to feed itself with certain type of food source. Every food source requires certain type of beak in order for the bird to be efficient in getting its nutrition, so depending on hat the bird eats, we can easily see a pattern in the beaks, where birds that eat nuts have one strong and shorter beak, the ones that eat warms and insects have thin, pointy one, the predator birds have claw like, sharp beak...
Trees remove Carbo Dioxide from the atmosphere, they produce oxygen, and they make soil healthier and more arable. I hope this helps! Brainliest would be great. Comment below if it helped.
Answer:
The temperature of the surrounding air increases when the atmospheric CO2 level increases.
Explanation: Carbondioxide gas is a very important gas in the environment but high amount of it cause damage to the organisms.
Carbondioxide gas is also called greenhouse gas because it has the ability to absorb or trap heat energy when the solar radiation goes into the space after hitting the earth surface. If the concentration of carbondioxide gas is increased, more heat energy will be trapped and thus increase occurs in the temperature of the atmosphere which results in global warming.
Answer: Missense mutation
Explanation:
Missense mutation is a type of point mutation where a single nucleotide is changed to cause substitution of a different amino acid. This in turns render the resulting protein non-functional.
In the case of sickle-cell disease, the sixth amino acid in the gene sequence, glutamate (GAG) is substituted with valine (GUA), due to Adenine nucleotide changed to Uracil nucleotide. Thus, missense mutation has occurred
Gametic cells
Mutations on somatic cells cannot be passed down to offspring. Rather mutations born on gametic cells are what can be passed down. This is because gametes are the cells involved in fertilization to form zygote that develops into individual organisms.
Explanation:
Mutation on gametic cells can occur within the time from the pre-gametic cell to the formation of a mature gamete such as sperm or egg.
Radiation from nuclear reactor accidents in Japan in April 2011, may damage the cell of the body both somatic and gametic. But only those in the gametic cells are passed down Children born to these Japanese people. Radiation causes double-stranded breaks in DNA that are hard to repair by repair mechanisms in the cell leading to mutations.
