How did Alfred Wegener use rock and fossil evidence to support his hypothesis of continental movement.

LuckyWell [14K]

Fossils and rocks identical to each other wet found on separate continents because rocks and the animals that formed those fossils can't swim the logical explanation was that the continents split after the rocks and fossils were formed

Two true-breeding pea plants are crossed. One parent is round, terminal, violet, constricted, while the other expresses the cont

Alexandra [31]

The question is incomplete as it lacks te end part of the question. However, the missing part is as follows:

In the F2 generation, all possible combinations of these traits were expressed in ratios consistent with Mendelian inheritance. Identify the four dominant traits, and enter them in ALPHABETICAL order in the blanks provided. [x],[y],[z],[a].

Answer:

The correct answer is :

x)axial

y)full

z)round

a)violet

Explanation:

True breeding organisms are organisms that carry two same alleles of a particular trait or character either dominant or recessive. In this given case the two breeding plants have four distinct traits, round, terminal, violet, constricted in one parent and wrinkled, axial, white, full in other.

In f1 there would be only dominant alleles for these characters will be expressed, that is already given in the question-

round, axial, violet, and full

The alphabetical arrangement of the dominant alleles are-

x)axial

y)full

z)round

a)violet

Describe pulmonary circulation pathway using the following terms: deoxygenated blood, left atrium, lungs, oxygenated blood, pulm

ehidna [41]

Definition:
"The type of circulation pathway in which venous blood is passed
from the right atrium of the heart through the right ventricle and
 pulmonary arteries to the lungs where it is oxygenated and its return via the pulmonary veins to enter the left auricle and participate in the systemic circulation".

Explanation:
There are two circulatory path in cardiovascular system namely pulmonary circulation and systemic circulation. Pulmonary circulation path allows for blood circulation through lungs for oxygenation while systemic circulation allows for transport of oxygenated blood to all parts of the body.

Pulmonary Circulation Pathway:
Pulmonary circulation pathway consist of:

1. Superior and inferior vena cava:
De-oxygenated blood from lower parts of the body enter to right atrium through inferior vena cava. Similary, deoxygenated blood from upper parts of the body enter to right atrium through superior vena cava.

2. Right atrium and right ventricle:
From right atrium the blood passes to right ventricle through tricuspid valve.

 3. Pulmonary artery:
Afterwards, the blood enters the pulmonary artery via the pulmonary valve. The pulmonary artery divides into two arteries with one artery entering the right lung and the other artery entering the left lung. When the blood reaches the lungs through the left and right pulmonary arteries, it moves over alveoli via the capillary beds. 

4. Left atrium and left ventricle:
After the blood gets oxygenated, it moves back to the heart and this time moves into the left atrium, completing the pulmonary circulation path.

In stage II, growth involves one or both ovaries and involvement of other organs.

In stage III, cancer involves one or both ovaries, and one or both of the following: (1) cancer has spread beyond the pelvis to the lining of the abdomen, and (2) cancer has spread to lymph nodes.

In stage IV, growth involves one or both ovaries with distant metastases to lungs, liver, or other organs outside the peritoneal cavity
