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).

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.

what causes fast rate of growth in eichhornia
Answer:
Due to short life cycle and mode of reproduction.
Explanation:
The main cause of the fast growth rate of Eichhornia is their mode of reproduction and shorter life cycle. Eichhornia reproduce through sexually and clonally. Its life cycle is only 10 days means that within 10 days the population of Eichhornia becomes double. It reproduces through sexual reproduction as well as asexual reproduction such as clonally which also contributes for the fast growth of eichhornia plant.
3. Which of the following is NOT a method that has been used to predict earthquakes?
A) Trying to observe precursors such as foreshocks and changes to animal behavior.
B) Watching changes in weather patterns.
C) Using past earthquake patterns.
D) Predicting stress accumulation based on how recently an earthquake occurred.
Predicting stress accumulation based on how recently an earthquake occurred is not the method that has been used to predict earthquakes. The correct option is D.
What is earthquake?Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault.
The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.
Erratic animal behaviour, such as fearful or puzzled pets, or birdcalls not typically heard at night, can be a clue that an earthquake is about to happen. Water levels in wells or artesian bores suddenly change.
It hasn't been possible to anticipate earthquakes by basing stress accumulation on how recently an earthquake happened.
Thus, the correct option is D.

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.

The orbit of the Earth around the Moon and its distance from the Sun.
B
The Moon's position relative to the Sun and Earth as it revolves around
Sun.
с
The rotation of the Moon on its axis.
The distance of the Moon to the Sun.
D
Answer:
B
Explanation:
The reason we see different moon phases is because of how the sun, earth and moon are relative to each other .
Answer:
As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.
Explanation:
Actually, the Moon rotates in the same period that it revolves, so we always see the same side (the white arrow keeps pointing to Earth). The differences in the Moon's appearance from one night to the next are due to changing illumination by the Sun, not to its own rotation.

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.

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.

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.

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.
