<h2>(A) is the correct option </h2>
Explanation:
- An organism is part of a community is correct,where species interaction occurs between different organisms
- A community is part of population is the incorrect statement because a community includes group of population of two or more different species
- An ecosystem is made up of only organisms is the incorrect statement because ecosystem is the community of both living and non living components of the environment and how they interact with each other
- A biome is the biotic part of an ecosystem is incorrect because biome includes the community of both plants and animals occupying a large habitat
Answer:
<h2>(14+16)/1000 *100= 3</h2>
Explanation:
Parental combinations are always more common then other recombinant progenies.
A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b and between b & c, then the double cross is that, which occurs in both.
Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.
So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3
Respiration is a chemical reaction that takes place in cells and allows them to release energy. Reactants are the substances that react together in a chemical reaction. In respiration the reactants are glucose and oxygen.
<span>Microevolution refers to changes in the genetic pool
of a species population. The changes in the genes (probably gene and allele frequencies)
are observed over short time periods hence are small changes. This is in comparison
to macroevolution that observes huge changes over longer time periods in the population that warrant that the new populations
is considered to be a new species</span>
Answer:
Use cooking methods that minimize/eliminate contact with water.
Explanation:
Vitamins are important nutrients found in fruits and vegetables. Vitamins can be easily leached out and it is therefore recommended that the vegetables should be consumed immediately after purchase or stored in an airtight container.
The use of cooking method that eliminate contact with water such as freezing, keeping in a close container will help retain the vitamins, reduce degradation rate and prevent it form been lost.
Cutting will allow easy definition of vitamins and result in its lost.
