Answer:
Option 1, 0
Explanation:
Complete question
Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown in a garden. All flowers are purple, yet there is some variation in the intensity of the purple color. The estimated heritability for this observed variation in flower color would be
- 0.
- 0.5.
- 0.75.
- 1.
- Cannot be determined without additional information
Solution
Given all the pea plants in the garden are homozygous purple (PP)
If we cross two PP parents, the following offspring will be produces
PP * PP
PP, PP, PP, PP
This means that all offspring are also homozygous purple.
Thus, chances of inheriting variation in the purple color of offspring are negligible. However, the variation in their color can be due to their individual interaction with the variable factors in the environment
Hence, option 1, 0 is correct
Viruses have both rna and dna
Answer:
Group 1 - Alkali metals; Group 4 - Elemental Properties
Explanation:
The elements in Group 1 are called Alkali metals and those are: Lithium, Potassium, Rubidium, Celsium, Francium and Sodium and the elements in Group 4 are called: Titanium, Hafnium, Zirconium and Rutherfoundium.
It's important that group 4 has no trivial name like the group 1 does, it belongs to the grouping of <em>transition metals </em>and those metals have several general properties. They are found in the middle of the periodic table.
The mantle has properties of both liquids and solids
Answer:
Explanation:
Parenchyma
1. They have thin cell wall.
2. Their cell wall is made up of cellulose.
3. They are unspecialized tissues.
4. The are found in soft part of the plant.
5. They undergo photosynthesis and can stored the food and also play important role in gaseous exchange.
6. There are spaces between the cells.
Collecchyma.
1. They are thick cell walls.
2. Their cell walls are made up of cellulose and lectin.
3. They are specialized tissues
4. They are found in plants leaves and petioles.
5 The do not undergo photosynthesis but act to give mechanical support to plants.
6. They have little intercellular spaces.
Parenchyma and collecchyma are both tissues found in plants..
