Answer:
4
Explanation:
Because all the living things need carbon to make protein,carbohydrates,lipids
They would not have the same shape because they would basically be the same as that particular vitamin. If a vitamin was the same shape as c then it would be vitamin c. Therefore, they would not be the same shape.
I think it is B. biome
Because biome means a large area dominated by characteristic plants and animals, such as a rain forest, desert, or tundra.
Answer:
3. An even number of chromosomes are required for synapsis during prophase I and proper pairing during metaphase
Explanation:
Mules are hybrids of a cross between a female horse and a male donkey. Horses contain 64 chromosomes while donkeys contain 63 chromosomes in their somatic cells respectively. This means that they each produce 32 and 31 chromosomes respectively during meiosis. A mule, hence, contains 32+31= 63 chromosomes in their somatic cells.
This chromosome number in mules are uneven for meiosis to occur because meiotic division requires that an even number of homologous chromosomes pair together in a process called SYNAPSIS during prophase I of meiosis I. This is impossible in a mule because of the uneven number of chromosomes in its cells.
Also, during metaphase of meiosis, the homologous chromosomes need to be properly aligned at the equator for separation to occur. This is also impossible in a mule considering the number of chromosomes that don't add up.
Due to this reason of unevenness in the number of chromosomes present in a mule, meiosis will not occur and if meiosis (gamete formation) does not occur, reproduction cannot take place. Therefore, the mule is a sterile species i.e. cannot produce offsprings via sexual reproduction.
Answer:
A) Chemosynthesis
Explanation:
Organisms, such as bacteria and other living organisms, use chemosynthesis when there is an absence of light. They use inorganic chemicals to produce energy through reactions.
