Difference between pure tone and speech audiometer

Biology
1 answer:
svlad2 [7]3 years ago
7 0

Answer:

Speech audiometry was performed on 15 children with secretory otitis media pre-and post-operatively and the findings compared with the pre-and post-operative pure tone audiograms. The results showed that in 30 per cent of cases pre-operatively the speech audiogram suggested a significantly worse hearing ability than that suggested by the pure tone audiogram (PTA). Where a PTA gives a borderline threshold disproportionate parental concern should be taken seriously as the hearing ability may well be worse than the PTA suggests.

Afina-wow [57]

Answer:

a. stem 1: Asparagus

b. taproot: 5. Carrot

c. lateral buds: 2. Brussels sprouts

d. modified stem: 6. Potato

e. leaf (petiole and blade): 4. Spinach    

f. petiole: 3. Celery

Explanation:

A plant stem is one of the structural axes of vascular plants that holds structures such as leaves, flowers, and fruits. The stem also transports water and dissolved (organic and inorganic) nutrients between the roots and the shoots. In some plants, the stem is modified in order to carry out other functions (e.g., storage, vegetative propagation, protection, etc). Potatoes are modified stems (i.e., stem tubers) ​that are connected by small stem sections known as stolons, and serve as food storage organs. A taproot is a central, and dominant root from which other roots sprout, which can be used by the plant to store water and food (e.g., in carrots and turnips). Lateral buds or axillary buds are meristematic regions growing from the axils of the leaves at the intersection of the leaf and stem, below the terminal bud. Leaves are composed of the 1-blade, also known as the lamina, which is the largest part of the leaf, and 2-the petiole, which is a stalk that supports the blade and connects it to the plant stem. Celery petioles play the same functions as a plant stem by acting as transport and storage organs.

Place the events of fertilization and implantation in order. 1. Implantation of the developing embryo. 2. The developing embryo
ANTONII [103]

Answer:

The correct order is

5, 4 , 3, 2, 1

Explanation:

The first stage is the fusion of sperm  with egg in fallopian tube which induces chemical reactions that prevents fusion of multiple sperm with one egg. This is known as preventing polyspermy.

After this the fused egg starts dividing and growing through the process of mitosis. The growing zygote reaches the stage of morula after few cell division and continues the division process till it reaches the stage of blastocyst.

The blastocyst now move down the fallopian tube to attach to the wall of uterus. This stage is known as implantation.

Hence, the correct order is 5, 4 , 3, 2, 1
