Based upon your experimental data, which muscle type exhibited the lowest threshold of stimulation in all conditions tested?a. Lower forelimb muscleb. Upper forelimb musclec. Calf muscled. Thigh muscle
Answer:
a. Lower forelimb muscle
Explanation:
The forelimbs are the limbs that are found in the front parts of the body Which includes the arm and its muscles this makes them Different from the hind limbs that are found are the back parts of the body which includes our leg.
Based on the experimental data obtained the lower forelimb muscle displayed the lowest levels of stimulation in all the tests conducted.

Pure-breeding pea plants with the dominant long-stem trait were crossed with pure-breeding pea plants with short stems. The F1 generation was allowed to self-pollinate. If the long-stemmed offspring of the F2 generation are test crossed, what fraction of their offspring are expected to have short stems? Select one: a. 3/4 b. 1/2c. 1/3 d. 1/4
Answer:
b
Explanation:
First, let us assume the long-stem trait to be represented by the allele A and its short stem counterpart by the allele a.
Pure-breeding long-stem = AA
Pure-breeding short-stem = aa
AA x aa
F1: Aa Aa Aa Aa
The F1 generation was allowed to self-pollinate
Aa x Aa
F2: AA Aa Aa aa
Test-crossing means crossing an organism of doubtful zygosity with a phenotypically recessive version of the same organism.
From the resulting F2, the long-stemmed offspring are of 2 genotypes - AA and Aa. If AA is test-crossed with a phenotypically recessive version:
AA x aa
Aa Aa Aa Aa
all the offspring are expected to have long stems.
If the Aa offspring is test-crossed with aa:
Aa x aa
Aa Aa aa aa
Half or 1/2 of the offspring are expected to have short stems.
Considering the second cross, the correct option is, therefore, b.

What are the components of DNA nucleotides?
DNA is a made up of molecules called nucleotides that each contain a (phosphate group, helium group, oxygen), a (carbon group, sugar group, hydrogen group), and a nitrogen base.
Answer:
Phosphate group, sugar group and nitrogen base
Explanation:
Hope this helps :)
Answer:
Phosphate group and sugar group
Explanation:
Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). A DNA molecule is composed of two strands.

Describe the basic storage mechanism for DNA using the words histone complex, nucleosome, chromatin and chromosome.
Answer:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. ... Nucleosomes fold up to form a 30-nanometer chromatin fiber, which forms loops averaging 300 nanometers in length.
Explanation:
Histones help to package chromosomal DNA inside microscopic nuclei. These are positively charged proteins that bind to negatively charged DNA to form complexes known as nucleosomes.
What are nucleosomes?A nucleosome is made up of about 150 base pairs of DNA rolled up around a core of histone proteins.
The nucleosomes recurrently fold in on themselves to tighten and condense the packaged DNA when forming a chromosome.
Histones help to package chromosomal DNA inside microscopic nuclei. These are positively charged proteins that bind to negatively charged DNA to form complexes known as nucleosomes.
Thus, in this way, DNA gets stored.

What is sun?
The Sun, a 4.5 billion year old yellow dwarf star and the center of our solar system, is a hot, burning ball of hydrogen and helium. It is the only star in our solar system and is located approximately 93 million miles (150 million kilometers) from Earth.
On our home planet, life as we know it would not be possible without the energy of the Sun. The Sun may appear to be a constant source of heat and light in the sky from Earth's perspective.
However, the Sun is a dynamic star that changes frequently and radiates energy into space. Heliophysics is the study of the Sun and how it affects the rest of the solar system. The largest body in our solar system is the Sun.
Therefore, The Sun, Moon, planets, and stars all rise in the east and travel westward across the sky because Earth rotates or spins in an eastward direction.

The cells found throughout the digestive system all look very similar.
true or false
Answer:
True
Explanation:
In the levels that make up the organization of life, CELLS are the smallest and simplest components of life. According to the hierarchy, cells make tissues, tissues make organs, organs make organ systems, organ systems make organisms. Based on this question, the DIGESTIVE SYSTEM falls under the SYSTEM category of the hierarchy meaning that it comprises of organs performing similar functions that makes it up.
However, these organs as well contain tissues and subsequently cells which makes up the digestive system. Since the cells, tissues, and organs all work together for the process of digestion, it means that the cells found in the digestive system are SIMILAR to one another in appearance.
