Answer:

The correct answer is option -  A. Gametophyte, C. spore, and D. sperm.

Explanation:

The egg cell of a plant is haploid in the cell which means it has only one set of chromosomes. The haploid cells arise from the meiosis cell division in parent sex cells. These parent cells are divided into four cells with half of the chromosome number in comparison to the parent cells.

The gametophyte, spore, and sperm all three are the product of the meiosis division and are haploid in number.

Thus, the correct answer is option - A, gametophyte, C. spore and D. sperm.

Explain incomplete dominance, using snapdragon<br> flowers as an example.
oee [108]

Answer:

Dominant allele does not completely conceal recessive allele.

Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.

Explanation:

Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.

For example, in snapdragons:

The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.

However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.

Hope this helped!

Answer:

Terrestrial  - Mercury, Venus, Earth, and Mars

Gas Giants  - Jupiter, Saturn, Uranus, and Neptune

Ice Giants - Uranus and Neptune

Explanation:

Gas plants are the planets that are composed mostly of the gases in them such as helium and hydrogen found in Saturn and Jupiter planets there are four planets known as the gas giants that are Jupiter, Saturn, Uranus, and Neptune. However, Uranus and Neptune planets are known as ice giants as these two planets are cold and remote and made up of completely different gases from the other two gas giants.

Terrestrial planets are the planets that are more rocky and compact in terms of their surface and these planets are inner planets of our solar system that are Mercury, Venus, Earth, and Mars.

When is cladistics more useful than linnaean taxonomy
katrin [286]

Answer:

D. When you are analyzing DNA of organisms

Explanation:

Cladistics is focused on tracing common ancestors, which relies not only on physical characteristics but also DNA evidences. Cladistics is also known as modern taxonomy. Linnean taxonomy is more on the physical characteristics, which is also called traditional taxonomy. As technology progressed so did taxanomic categories, which allowed researchers to compare DNA to determine similarities in seemingly unrelated animals.
