Cell is the smallest unit of life.
differentiate between middle and inner part of ear
Answer:
middle= This is the part through which sound travel inside the ear to the eardrum through the auditory canal . sound causes the eardrum nad it's tiny attached bones in the middle portion of the vibration and conducted to the nearby cochlea
inner part= the cochlea is the part of the inner ear . its main function is to transform sound into nerve impulses......

What led to the significant growth in the study of DNA after 1977 and why?
18. Replicate the following four DNA strands using what you know about complementary base pairs.
a. AATACGTCCAGATTTT
c. CCCGCGGAATATACA
b. TTAACCGAGTTCAGA
d. AGGGCTACTTCAGAC
Answer:
a. TTAGCAGGTCTAAA
b. GGGCGCCTTATATGT
c. AATTGGCTCAAGTCT
d. TCCCGATGAAGTCTG
The replication can be TTATGCAGGTCTAAAA, GGGCGCCTTATATGT, AATTGGCTCAAGTCT, and TCCCGATGAAGTCTG respectively.
What is complementary base pairing?Complementary base pairing occurs when guanine always hydrogen bonds to cytosine and adenine always binds to thymine in DNA.
In comparison to the A-T bond, which always shares two hydrogen bonds, the bond between guanine and cytosine shares three hydrogen bonds.
Each strand of the double helix contains all of the information required to reconstruct the other half using the base pairing mechanism.
The strands are said to be complementary because each can be used to make the other.
Complementary base pairing describes how the nitrogenous bases of DNA molecules align with one another. The double-helix structure of DNA is also due to complementary base pairings.
TTATGCAGGTCTAAAA, GGGCGCCTTATATGT, AATTGGCTCAAGTCT, and TCCCGATGAAGTCTG are possible replications.
Thus, these are the complementary base pairing for the given codes.

For example, when the intensity of light entering the eye increases, a ____________ reflex is triggered, and the circular muscles of the iris are stimulated to contract.
Answer:An increase in light intensity causes both pupils to contract (see iris) even if only one retina is directly stimulated. This is known as a consensual reflex. Conversely, a decrease in light intensity causes dilation of the pupils

if you have been to a beach for a whole day, then you have seen tides roll in and out. What causes
Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Answer:
it's caused by the gravitational forces from the moon.

Explanation:
Renewable energy sources account for the majority of energy production. Please select the best answer from the choices provided T F.
Renewable source of the energy is defined as the energy collected from renewable sources like wind, water, and light, which can be replenished on the Earth over time.
The given statement is False.
Renewable energy accounts for 20% of the total utility scale. The majority of the energy is derived from non-renewable sources. The non-renewable source of energy cannot be replenished over time and can be exhausted after certain years.
Renewable resources like, wind and waves are used to obtain energy by applying scientific equipment and technologies. The output of renewable sources of energy is lesser as compared to non-renewable sources of energy.
Thus, non-renewable sources of energy account for the majority of energy production.

A cross between two mice with long tails and brown fur produced the four types of offspring as listed.
• Long-tailed with brown fur
• Long-tailed with white fur
• Short-tailed with brown fur
• Short-tailed with white fur
Which genetic mechanism best explains the results of this cross?
A independent assortment
B. Crossing-over
C. gene linkage
D. dependent assortment
Answer:
B
Explanation:
The genetic mechanism that best explains the results of this cross is independent assortment. The correct option is A.
What is independent assortment?According to Mendel's law of independent assortment, alleles from two (or more) different genes are sorted into gametes independently of one another.
In other words, the allele received by a gamete for one gene has no effect on the allele received for another gene.
Independent assortment occurs when alleles from at least two genes are assorted into gametes independently.
As a result, the allele inherited by one gamete has no effect on the allele inherited by the other gametes. Mendel observed that the transmission of various genes appeared to be separate events.
Independent assortment is the genetic mechanism that best explains the results of this cross.
Thus, the correct option is A.

What is the relaxed form of dna in a cells nucleus?
Answer:
The relaxed form of DNA that can be found in the nucleus is referred to as chromatin. This form of DNA is observed when the cell is not dividing.
Explanation:
hope this helps
The relaxed form of DNA in a cell's nucleus is called chromatin.
CHROMATIN:Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones. This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.

Explanation:

A submicroscopic virulent agent that infects animals, plants, bacteria etc. is called viruses. They are capable of copying inside host cells only. Viruses cause many diseases in animals and plants.
The correct discussion is:
Student A believes that viruses are not living organisms.
The student's statement can be explained as:
The virus is not capable of reproducing on its own without a host system. Therefore they cannot fit in the definition of a living organism. They just have a genetic material encapsulated in protein coats and do have defined cell structures, unlike prokaryotes and eukaryotes.Therefore, viruses are not contemplated to be living.

Animalia that consist of many cells with an organized nucleus, have two parents, and eat food.
What are the characteristics of Animalia?Animal cells are the basic living unit of organisms in the kingdom Animalia. They are eukaryotic cells, which means they have a true nucleus and special structures called organelles that perform various tasks.
All members of the Animalia are multicellular, and all are heterotrophs (meaning that their nutrition depends directly on or indirectly on other organisms). Most swallow food and digest it in an internal cavity. Animal cells lack the rigid cell walls characteristic of plant cells.
