How does sand silt and Clay affect soil nutrients and plants

Biology
1 answer:
Ghella [55]3 years ago
6 0
Sand is granular and coarse meaning that water and nutrients can flow through it quite easily. Clay on the other hand has very fine particles that cling together to form a waterproof substance which traps/ stops any nutrients or water from moving down. Clay's also quite difficult for plants to get their roots into. Silt has a texture between clay and sand, meaning that it is the ideal substance as it allows the best water and nutrition movement in the soil. Most plants will grow best in silt, but there are some plants who are more adapted to living in sand (e.g. Marram grass) or clay.

Suppose that allele D produces tiny ears and allele d produces normal ears. A heterozygous male with the Dd genotype mates with
kotegsom [21]

Answer:

The correct answer is 35 percent.

Explanation:

Allele D produced tiny ears, and allele d produces normal ones. If a heterozygous male with Dd mates with the homozygous female with dd, then generally, the expected offspring produced will be 50 percent with tiny ears, and 50 percent with normal ears.  

However, in the given case, the penetrance is 70 percent. Thus, the probability of the offspring with tiny ears will be:  

Penetrance = 70 %

Probability = 70 % of 50 % of 100

= 70/100 * 50/100 * 100

= 35 %

Hence, the probability of the offspring with tiny ears is 35%.

agasfer [191]

Your answers would be:

1. Taxonomy

2. Genus

3. Species

4. Phylum

5. Class

6. Order

7. Family

8. Kingdom

9. Domain

10. Six Kingdom System

11. Hominid

1.Taxonomy is the practice of categorizing organisms and naming them. All organisms are classified into specific groups and are then given a scientific name.

2. Genus is one of the more specific grouping and it is the genus that makes up the first part of the scientific name. The organisms are grouped based on their characteristics, traits, qualities and/or features.

3. Species is the most specific among all classifications. It is distinguished though as the group that categorizes organisms based on their ability to reproduce with each other.

4, Phylum is one of the broader categories/groups. They distinguish the different organisms based on their characteristics also but are not as specific. It divides the different kingdoms into smaller groups. For example, Kingdom Animalia would have phylum chordata which includes all vertebrates.

5. Class divides phylums down into more specific features. For example, phylum chordata is divided further into classes such as mammalia (mammals), reptilia (reptiles), Aves (birds), amphibia (amphibians), and the like.

6. Order again, is more specific. It divides classes into different groups once again. So for example, for humans, we are classified as Class mammalia and then we belong in the order of primates.

7. Family on the other hand comes after order. It is more specific and comes right after order. Again, using humans as an example, our family is hominidae, which puts organisms that are distinguished for their ability of walking upright.

8. In the Linean biological taxonomy the highest classification was Kingdom. In his classification system, organisms were divided into only 3 kingdoms. As technology and discovery expanded, we have added to it.

9. Domain is the higher rank than kingdom. It is the broadest among all. There are three main domains now, we have Eukaryota, Arachaea, and Bacteria. In the old system

10. The 6 Kingdom System is the most recent classification system. The organisms are divided into 6 kingdoms:

  • Animals
  • Plants
  • Protists
  • Fungi
  • Archaebacteria
  • Eubacteria

11. Hominid is a member of Hominidae family. These are species that share about 97% similarity to the DNA of the modern human. The species included in the hominid family have simple cultures and have a capacity to communicate through language.
