Answer:
Meristematic tissue.
Explanation:
Meristematic tissue contains stem cells which can differentiate into permanent cells. This tissue is at all continuous growth points in a plant, at the apical buds ( where leaves and flowers form) and at the ends of roots.
- dermal tissue is in animals - this refers to the tissues associated with skin
- vascular tissue refers to the xylem and phloem of a plant- no growth occurs here.
- Permanent tissue is tissue which has already differentiated and grown. This is the final form.
Answer:
Both parents are heterozygous carriers.
Explanation:
Both parents are heterozygous carriers. Sickle Cell Anaemia is usually referred to as a recessive condition since an individual must have two copies of the sickle gene in order to have the disorder.
Since neither of the parents is ill, both of them must be heterozygous carriers for the child to have the disorder
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.
Gamates cells have half the chromosomes
Answer:
Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens.
