B. Photosynthesis
C. Lactic Acid Fermentation
D. Alcoholic Fermentation
Bacteria living deep within the Earth's crust would use chemosynthesis, a type of cellular respiration, to obtain energy. They use inorganic materials to generate energy because light for photosynthesis doesn't reach these depths.
The bacteria found deep within the Earth's crust would likely rely on a process called chemosynthesis to obtain energy. Unlike photosynthesis, which uses sunlight for energy, chemosynthesis utilises chemicals from the surrounding environment. It's a kind of cellular respiration where energy is generated from inorganic substrates. In the deep parts of the Earth's crust, light doesn't penetrate, making it impossible for photosynthesis to occur. Instead, bacteria can obtain energy by converting inorganic materials, like iron, sulfur, and other minerals, into usable energy. Therefore, the correct answer is A. Cellular Respiration.

Answer: Option C
Out of the 20 resulting offspring of the test cross, 10 (50%) will be tall.
Explanation:
Let True-breeding tall plant be "TT"
Let short plant be tt
On crossing, all offspring will be "Tt"
Test cross involves the breeding of an individual with a phenotypically recessive individual. The test cross of offspring "Tt" against "tt" will then yield an equal ratio (1:1) of Tt to tt.
Thus, out of the 20 resulting offspring of the test cross, only 10 (50%) will be tall.
When a true-breeding tall pea plant is crossed with a short plant, all the F1 offspring will be heterozygous tall. Upon performing a test cross of a heterozygous F1 tall plant with a short plant, about half of the resulting offspring should be tall. Thus, out of 20 offspring, approximately 10 (Option C) should be tall.
In garden peas, the allele for tall plants (T) is dominant over the allele for short plants (t). A true-breeding tall plant has two copies of the dominant allele (TT), while a short plant has two recessive alleles (tt). When you perform a test cross between a heterozygous tall plant (Tt) and a short plant (tt), the results should theoretically yield a 1:1 ratio of tall to short offspring. Since the question states the tall plant is true-breeding and crossed with a short plant, all offspring from this initial cross would be heterozygous tall (Tt). Each of these offspring, when test crossed with a short (tt) plant, would produce tall and short offspring in a 1:1 ratio.
Therefore, out of 20 offspring from the test cross, approximately half should be tall and half should be short. So, the expected number of tall offspring would be about 10.
The correct answer to the question is option C- 10.

Answer:
Because a new solution is to be carved for a old problem, therefore creativity is required.
Explanation:
Finding solution to old problem requires an individual thinker to think out of the box solution which have been never implemented or were implemented in an incorrect manner.
In order to think out of the box , hell lot of bigger dose of creativity is required. When a novel and appropriate solution is required, creativity becomes essential
Problem solving is an skill and a logical thinker can only imbibe it thereby using his/her creative thinking.
Answer:
Explanation:
National Park Service has been keeping the native ponies on Ocracoke Island since the 1960s. It is believed that these ponies arrived and left by the ships. These ships required to lower their load thus they left the ponies on the Island. These ponies are known as Ocracoke ponies and also called as Banker ponies. These ponies share a link to old Spanish horses genetically. The unique characteristics of the ponies include one fewer lumbar vertebrae, greater bone density, short necks, wide foreheads, and one fewer rib.
Answer:
are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles
Explanation:
B. RNA contains ribose and thymine
C. RNA contains uracil and ribose
D. RNA contains uracil, thymine, and ribose
DNA and RNA differ in their structure and function. DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil. RNA transmits genetic information from DNA to proteins.
The key differences between RNA and DNA are found in their structure and function. DNA (Deoxyribonucleic Acid) contains deoxyribose sugar, has thymine as a base (along with adenine, guanine, and cytosine), is double-stranded and primarily functions as the storage material for genetic information.
On the other hand, RNA (Ribonucleic Acid) has ribose sugar, contain uracil instead of thymine (the other bases are adenine, guanine, and cytosine), is single-stranded, and serves as the intermediary in the process of converting genetic information from DNA into proteins. Thus, the correct answer is: C. RNA contains uracil and ribose.
