They help in that, many recently discovered fossils form series that trace the evolution of modern species from extinct ancestors. Patterns in the distribution of living and fossil species tell us how modern organisms evolved from their ancestors. Evolutionary theory explains the existence of homologous structures adapted to different purposes as a result of descent with modification from a common ancestor.
The question is incomplete as it does not have the options which are:
A. Phloem
B. Xylem
C. Apical meristem
D. Root cap
Answer:
The correct answer will be option- Root cap
Explanation:
The plant growth takes place not only above the surface but below the surface also in the roots. Roots continually grow to absorb more water and nutrients to support the growth of the plant.
The roots are protected by a layer of protective cells forming a structure called root cap below the root. The root cap protects the roots, secretes a substance which helps the growth of the root and the sense gravity.
In the given question since the roots are not able to grow therefore the damaged part will be the root cap.
Thus, the root cap is the correct answer.
Answer:
The statement by the patient which indicates that further teaching is needed is:
What to do if I am facing side effects of the drugs?
Explanation:
Atopic dermatitis: It is the most common form of Eczema and appears as red itchy rash on cheeks, arms and legs. Mostly children suffer from it. It is a chronic condition and may be associated with Asthma and Hay fever.
Note: There is no definite treatment for it but different agents (drugs) along with precautions can alleviate the symptoms.
Pimecrolimus: It is an immunomodulating agent of calcinuerin inhibitor class used for the treatment of atopic dermatitis.
The cell theory consists of:
1. all living organisms are made up of cells
2. cells are the basic structural/organizational unit of all organisms
3. all cells come from pre-existing cells
Answer:
1 in 16
Explanation:
When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.
