Photsynthesis to make food
The selection of more effective which is against recessive alleles in haploid organisms than diploid organisms. This is because haploid organisms contain a single set of alleles if a deleterious allele is present in haploid organisms which will produce its effect immediately as there will be no dominant allele which can prevent the expression of the recessive allele as it happens in diploids. Recessive allele will not produce its effect in presence of the dominant allele in the case of heterozygote which is Aa.
Where there is haploid the selection will be more effective when removing recessive alleles in the population. It is the homozygous recessive condition which as aa then the selection will act against recessive alleles.
Answer:
At its closest, the Sun is 91.4 million miles (147.1 million km) away from us. At its farthest, the Sun is 94.5 million miles (152.1 million km) away. The Earth is closest to the Sun during winter in the northern hemisphere.
Explanation:
Answer:
i. (answer is in the file I attached)
ii. underground parts of the plants are thick , fleshy and swollen because they store food in the form of starch.
iii. Spines that have been converted into leaves. These prevent water loss by reducing surface area. The spines help defend the cacti from predatory animals. To decrease water loss due to evaporation, the cuticle is very thick and waxy.
iv. this plant is called a water lettuce it's leaves are modified to form modified to form hydrophyte They are aquatic plants that have evolved to thrive in water. This is capable of comprehending with aquatic macrophyte, which will be entirely submerged in water and in some circumstances allowed to float on the water's surface.
hope this helps :)
