Answer:

Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.

Explanation:

In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.

Answer: The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells- sperm and eggs. only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.

The sweet potatoes found underground contain starch.
Stella [2.4K]

Answer:

The correct answer s - by the photosynthesis process.

Explanation:

Plants use the sunlight to convert the atmospheric carbon dioxide and water to oxygen and glucose for their food and energy, this process is called as photosynthesis. In This process, glucose is formed that is linked together to form the storage carbohydrate form, starch, that can use by plants later and store in the different parts of the plants.

In plants like potato and sweet potato or the plants that has tuber or grains, store the starch in their tuber or grains by transporting the starch to the these parts.

Two phenotypically normal parents have a child with CF. i. What are the genotypes of each parent? ii. What is the probability th
katen-ka-za [31]

To first dive into your question, here are some vocabulary terms that I will be using and will be helpful to you as well.

  • Homozygous dominant (BB): <em>Is not affected by cystic fibrosis</em>.
  • Homozygous recessive (bb):<em> Is affected by cystic fibrosis</em>.
  • Heterozygous (Bb):<em> A carrier for cystic fibrosis</em>.
  • Phenotype (Ex: Having cystic fibrosis): <em>The appearance of an allele pair</em>.
  • Genotype (Ex: bb): <em>The genetic makeup of an allele pair</em>.

We know that if both of the parents are phenotypically normal, there is no way that they can be homozygous recessive (bb), or have cystic fibrosis. We also know that since they have a child with this disease, they can't be homozygous dominant (BB) either. This means that <u>both parents have to be carriers (Bb)</u> in order for them to have a child with cystic fibrosis.

Below I have attached a Punnett square with both of the heterozygous parents.

<em>Each child they have will have a </em><u><em>1/4</em></u><em> or </em><u><em>25%</em></u><em> chance of having cystic fibrosis.</em>
