Answer:
The two nucleotides are located on DNA strands that are parallel to each other
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is one of the two types of nucleic acids. It is a molecule composed of a nitrogenous base, pentose sugar and a phosphate group. According to the information given in this question, Adenine is the last nucleotide at the 3' end of one strand of DNA. The following are factual about the nucleotide;
- Since DNA is a double-stranded molecule, the Adenine nucleotide will be base-paired with Thymine nucleotide (complementary base pairing) on the other DNA strand.
- Since complementary DNA strands are opposite to one another, this means that if the adenine has an unlinked 3' hydroxyl group, then the thymine must have an unlinked 5' phosphate group.
- Nucleotides in a DNA strand are joined to one another via a covalent bond called PHOSPHODIESTER BOND. Hence, the adenine and the thymine are each bonded to the previous nucleotide in the strand by a phosphodiester bond.
- In the complementary base pairing between two nucleotide bases, there are two hydrogen bonds between the adenine and thymine nitrogenous bases i.e. A=T.
- DNA strands that make up a molecule are complementary and opposite to one another, hence, they are said to be ANTIPARALLEL.

The reproductive handicap for sexual reproduction refers to __________. View Available Hint(s) The reproductive handicap for sexual reproduction refers to __________. diluted genetic investment in offspring dependence on hormonal cycles the need to provide energy for the offspring the difficulty of finding mates the need for maturation prior to reproduction
Answer:
diluted genetic investment in offspring.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
Generally, asexual reproduction produces more reproductive offsprings than sexual reproduction, this is referred to as a reproductive handicap.
Hence, the reproductive handicap for sexual reproduction refers to diluted genetic investment in offspring.
This ultimately implies that, the sexually reproducing female would have a 50% genetic material passed to its female and male offspring.
However, sexually reproducing female has 100% transfer of her genetic materials through asexual reproduction.

How is density affected when the salinity increases?
Answer:
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure
[tex] \huge \sf \green{Question}[/tex]
How is density affected when the salinity increases?
[tex] \huge \sf \green{Answer}[/tex]
When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases.
Salinity describes how much salt is dissolved in a sample of water. The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.
Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answer: Your correct answer would be both A & B.
Explanation: A is the correct answer because both of these models are in fact models of our solar system. The geocentric model had Earth at the center of the solar system with all the other planets and sun rotating around us. The heliocentric model is the accepted model of our solar system today with the sun at the center and planets rotating in slightly elliptical fashions around it due to gravitational pull. B is also correct because as I just explained, both models position Earth in relativity to the sun though both models vary greatly. The aim of both of these models was to specify where Earth was exactly in the solar system. I hope this has been of use to you! Please do not hesitate to ask if you have other questions :)
The two correct statements about the geocentric and the heliocentric model are:
They both show the position of Earth relative to the Sun. They both are models of the solar system.The geocentric model
The geocentric model has the assumption that the earth is at the center of the universe. The sun and the planets are said to revolve around the earth in this model
The heliocentric model:
The heliocentric model has the assumption that the sun is at the center of the universe. The earth and the planets revolve around it.

D all options.
Answer:
Cell division is found to occur in both groth and reproduction.The answer is D
Answer:
D all options.
Explanation:
Cancer
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Reproduction
Cell division usually occurs as part of a larger cell cycle. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle.
Growth
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues

Answer the following questions:
⦁ What is the purpose/function of the Respiratory System?
⦁ What is the purpose of the tiny hairs called cilia in your nose?
⦁ What are the purposes of the pharynx?
⦁ What is the purpose of the epiglottis?
⦁ How is the respiratory system linked to the cardiovascular system
Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

ANSWER: b 3. Proinsulin is converted into insulin by: a. proteolytic excision of a specific peptide. b. allosteric binding of glucose. c. phosphorylation to the active form. d. removal of phosphate by converter enzymes. e. none of the above. ANSWER: a
Answer:
1-For the first one, the statement which is not correct about enzyme regulation is the statement e which is The activity of an enzyme is covalently affected by allosteric regulators
2-The example which does not have a zymogen and activating protease is example b which is procarboxypeptidase and elastase.
3-The process by which proinsulin is converted into insulin is by method a which is proteolytic excision of a specific peptide.
Explanation:
1-All the other statements are correct as indicated below:
a-Enzymes can be inhibited by the products they produce. This is true because the rate of production is reduced in cases of some products. this indicates that the enzymes are not being able to further act.
b-Enzymes can be inactivated by the addition of a functional group. This is true because enzymes can be activated and inactivated manually.
c-Coenzyme and substrate availability can regulate enzyme reaction rate. This is true because lack or shortage conenzyme or substrate can reduce the reaction rate due to lack of availability of required components.
d-The reaction rate slows as equilibrium is approached. This is true as the reaction reaches equilbrium less products are converted back to reactants and less reactants are converted into products.
2-
Similarly all the other examples for 2 have either an activating protease or zymogen except procarboxypeptidase and elastase.
3-
The proinsulin has a specific peptide which is excised thus only option a is correct.

3.What are the functions of vacuoles, lysosomes, and the
cytoskeleton?
Answer:
In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.
Explanation:
Storage, waste disposal and structural support are the functions of vacuoles, lysosomes, and the cytoskeleton.
The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.

Explanation:
The Hardy-Weinberg law is established in it is that in a sufficiently large population, in which the matings occur randomly and that is not subject to mutation, selection or migration, the gene and genotype frequencies remain constant from generation to generation, once a state of equilibrium has been reached that is reached after one generation at autosomal loci. A population is said to be in equilibrium when alleles from polymorphic systems maintain their frequency in the population through generations.

Which of the following explains why geological events occur?
a The lower mantle is solid rock
b The crust is the same thickness throughout
c The crust is a single layer throughout
d The lower mantle is hotter
Answer:
Hey there,
The answer is A.
This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.
They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.
It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.
It is not C as the mantle is semi molten not solid.
And it’s not D because it’s not a single layer but multiple layers.
So A is the answer.
