Answer:
The correct answer will be option-A
Explanation:
In the pedigree analysis, the description of a trait help shows the relation of a trait linked to a gene.
The pedigree analysis is usually used to determine the heredity of a disease in a family which has been described in the question also as
1. The trait is rare and present in both sexes- this shows that it is independent of sex chromosomes and since is rare is recessive.
2. A consanguineous mating- mating between close relative which result in autosomal recessive trait as the genes for the trait must be present on both the parents which happen only when they are closely related.
Thus, option-A is the correct answer.
B. lakes
C. clouds
D. water vapor
Answer:
Index fossil that is also known as indicator fossil is used to determine the age of the layers of the rocks. It says that the new layer of sedimentary rocks lie over the old layer.
The deeper we go, the older the rocks we will find. Index fossil of animals that lived or survived only for a short period of time are very useful. An example of index fossil can be Ammonites that were found in Mesozoic era that was about 25-35 million years ago.
Index fossils are used by geologists and palaeontologists to determine the relative age of rock layers and identify different geological periods. They are effective markers of time because they appear in a consistent, limited time span.
Index fossils are a powerful tool used by geologists and palaeontologists. Specifically, these fossils are used to determine the relative age of a layer of rock and identify geological periods. This is possible because index fossils are found to occur in a particular time span, and not beyond that.
For example, let's suppose a fossil of a creature that we know lived about 100 million years ago is found in a rock layer. This suggests that the rock layer would also probably be of the same period. Thus, index fossils serve as benchmarks or points of reference to determine the age of the surrounding materials.

Deep
Explanation:
Answer:A
Explanation: CAPPING
II. A well-hydrated person is likely to have higher blood levels of angiotensin II than a dehydrated person.
III. Angiotensin II helps to slow the rate at which urine is produced.
IV. A class of drugs known as ACE inhibitors promote (enhance) the formation of angiotensin II.
Answer:
I. Angiotensin II is a hormone that is secreted by the kidneys.
Explanation:
The angiotensin II is a vasoconstrictor molecule secreted by the kidney. This hormone is known to be involved in the regulation of blood pressure and has effects on water and sodium intake.
Angiotensin II plays roles in the immune response and in the regulation of inflammatory response pathways
A. Ecology
B. Chemistry
C. Meteorology
D. Geophysics
B. lichens
C the erosion of rock by weather
weather
D.volcanic eruptions
Factors such as the decomposition of organisms and the erosion of rock by weather contribute directly to soil formation except volcanic eruptions which produce rocks.
Soil is the topmost layer of the earth on which plant grow.
Soil is important to plants as it provides the plants with the nutrients they need to grow.
Soil can either be formed directly by the breaking down of large rock particles through plant, animals and weather conditions.
The formation ofsoil involves can be due to:
Therefore, all the above factors contribute directly to soil formation except volcanic eruptions which produce rocks.
