Explain why the resistance of the current path through the extracellular fluid is much smaller than the resistance of the current path through the axoplasm?
Answer:
The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.
Explanation:
The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.
Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.

Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.

The study of chemical reactions in cells is useful in the analysis of metabolism. What is metabolism?
Answer:
metabolism refers to all chemical reactions that allow to the cells carry out their functions
Explanation:
In a wide sense, the term metabolism refers to the chemical reactions that occur in the cells of a particular organism in order to sustain life. In a cell, the term metabolism can be delimited as all the chemical reactions inside the cell in order to carry out all cellular functions (e.g., growth, development, reproduction). Metabolic reactions can be divided into 1-catabolic reactions, which typically release energy and involve the breakdown of larger molecules into simpler ones, and 2-anabolic reactions, which typically require an input of energy stored in the chemical bonds of complex molecules.
Discuss how population size and natural events could limit the resource availability in an ecosystem.

Imagine that you are walking in the woods for fun and all of a sudden you see amountain lion. Your hair stands up, you begin to sweat and your heart beataccelerates as you prepare to run away. What fueled the energy for the run?
a. The binding of epinephrine to tyrosine kinase receptors and consequent initiation of a response that leads to muscle contraction that allows you to run
b. The activation of a G-protein receptor that leads to the secretion of a protein that makes you run.
c. The binding of epinephrine to a G-protein coupled receptor with the subsequent activation of a nuclear receptor.
d. The initiation of a signaling mechanism that leads to breakdown of glycogen into glucose that can then serve as the fuel for ATP production.
e. All of the above
Answer:
The correct answer is - D. The initiation of a signaling mechanism that leads to the breakdown of glycogen into glucose that can then serve as the fuel for ATP production.
Explanation:
In challenging or dangerous conditions, the body releases a hormone called Epinephering which is a fight or flight hormone that provides a high amount of energy for the particular action.
Epinephrine hormone binds to beta-adrenergic receptors present on muscles and responsible for the rapid conversion of glycogen to glucose-1-phosphate. The glucose results in condition to rapid synthesis of ATP in muscles and thus helps in muscle actions.
Another aspect of the competitive exclusion principle is that animals that compete within the same environment may eventually come to occupy their own NICHE. A niche is a way of life, and includes how the animal lives, what it eats, reproduction strategies and more. For example, a hawk and owl both eat the same kinds of food, but the owl hunts at night and the hawk during the day. How did your final ecosystem?
Answer:
Both hawk and owl share the same habitat or ecosystem.
Explanation:
According to competitive exclusion principle, two species can't coexist in the same environment if they occupy exactly the same niche but in the case of hawk and owl, it is possible because both have different times of eating habits. Hawks hunts at daytime while on the other hand, an owl hunts at night so both share the same habitat due to difference in their niche and they are present in the same ecosystem.

By the 1940s scientists realised that DNA contained the code for life, and in 1953 Watson and Crick at Cambridge University discovered how information was stored in DNA and transferred to the next generation. In 1984 Professor Alec Jeffreys discovered the variations in DNA, unique to each individual.
what's DNA is copied and cell prepares to divide phrase
Answer:
Mitosis is the process in which a eukaryotic cell nucleus splits in two, division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
a cross that results from a yellow and a purple allele together will result in what color corn kernel?
1.) yellow
2.) purple
3.) orange
4.) doesn’t exist
Answer:
1.) yellow
Explanation:
The high possibility of corn kernel colour is yellow if the yellow colour allele is dominant because the dominant trait or allele always appear in the offspring while on the other hand, the recessive allele does not appear in the shape and structure of the offspring so we can say that dominance is the reason for the appearance of colour in the seed or kernel.
what are the two strands of DNA
Answer:
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T). But there are two types of DNA in the cell – autosomal DNA and mitochondrial DNA. Autosomal DNA (also called nuclear DNA) is packaged into 22 paired chromosomes. In each pair of autosomes, one was inherited from the mother and one was inherited from the father.
Extra: Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner. Before replication can occur, the length of the DNA double helix about to be copied must be unwound.

There are 2 chromosomes.
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Human cells contain 23 pairs of chromosomes (46 chromosomes in total). Each chromosome is formed by 2 strands of DNA that hydrogen-bonded to each other make the classic DNA double helix (double-stranded DNA).
Comment on the folding of protein in vaccum
Answer:
Protein folding is a process by which a polypeptide chain folds to become a biologically active protein in its native 3D structure. ... The amino acids in the chain eventually interact with each other to form a well-defined, folded protein. The amino acid sequence of a protein determines its 3D structure.

The least genetic variation will probably be found in the offspring of organisms that reproduce using
Answer:
The least genetic variation will probably be found in the offspring of organisms that reproduce using asexual reproduction.
In the descendants of organisms that use mitosis to build a bigger population, the least genetic variety will likely be observed.
What is mitosis?Mitosis results in an increased population. Unlike other types of animals that were present at the time, woolly mammoths became extinct thousands of years ago.
Numerous processes can introduce genetic variety, such as mitosis alterations, meiosis crossing over and random orientation, and random fertilization.
All mitotic children share a similar genetic makeup since the duplicate chromosomes' genes are passed down to each succeeding cellular generation.
Each gamete has a unique DNA set because of meiosis's autonomous sorting and recombination. In the resultant zygote, this results in a unique mix of genes.
Therefore, in organisms that use mitosis to build a bigger population, the least genetic variety will likely be observed.
