Answer:
1. D. Only DNA contains genetic information
2. D. Nitrogen and Phosphorus
Explanation:
1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.
Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.
DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.
2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
<span>False. The plasma membrane is the outer layer of the membrane and its primary purpose is to protect the cell from its surroundings. It is selectively permeable to allow ions and other organic molecules to pass through and regulates which molecules are allowed in and out of the cell. It is a phospholipid bilayer that are placed back-to-back.</span>
Answer:
When two heterozygous short haired rabbits are crossed, the short hair being dominant and the long hair recessive, the phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1.
Explanation:
The crossing of two hybrid individuals for a trait has the probability of producing <u>offspring that exhibit the dominant trait at 75% and the recessive trait at 25%, with the ratio of the dominant trait to the recessive trait being 3:1</u>.
Considering the hair length trait, in rabbits the short hair (L) is the dominant trait and the long hair (L) is recessive, two heterozygous hybrid individuals Ll are crossed:
<em><u>Genotype of the parents</u></em>:
Ll X Ll
<u>Punnett Square
</u>
Alleles L l
L LL Ll
l Ll ll
Where the offspring have a genotype:
<em>Ll 50%
</em>
<em>LL 25%
</em>
<em>ll 25%
</em>
With a ratio Ll:LL:ll of 3:1:1.
Phenotype:
<em>Short hair 75%.
</em>
<em>Long hair 25%.
</em>
Phenotypic ratio short hair: 3:1 long hair.
In the crossing of two heterozygous short-haired rabbits, taking into account the dominance of the short hair, phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1
The highest tier in cell hierarchy is the macro tiers
