Answers

Answer 1

Answer:

D

Explanation:

To copy original DNA strands into complementary strands​

Answer 2

The option (D) is correct. To copy original DNA strands into complimentary strands​.

What are complementary strands of DNA?

Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.

Moreover, the complementary strand for DNA must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions. First write the correct base pairing below the original sequence and label the 5' and 3' ends.

Therefore, the upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA.

An RNA sequence includes 12 nitrogenous bases, AUGGUGCAUGUC. What is the maximum number of amino acids for which this sequence could code?

A). 4

B). 3

C). 2

D). 12

Answers

Answer:

In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).

Explanation:

Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.

From the sequence:

AUGGUGCAUGUC

Four codons are obtained, each of which encodes a different amino acid:

Codons:          AUG-GUG-CAU-GUC

Amino acids:  Met - Val - His - Val

Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.

A. Outegumentary
B. Integumentary
C. Excretory

Answers

Answer:

b

Explanation:

Integumentary system helps regulate body temperature and water loss. Thus option B is correct.

What is the integumentary system?

In our body integumentary system is present in the outer layer. It’s made up of your skin, nails, hair, and the glands and nerves on your skin. It acts as a physical barrier — protecting your body from bacteria, infection, injury and sunlight. It also helps regulate your body temperature and allows you to feel skin sensations.( like hot and cold.)

Integumentary system present in skin:-

Dermis, epidermis, Hypodermis

Integumentary system present in nails:-

Nail plate, Nail bed, Cuticle, Matrix, Lunula

Integumentary system present in hair:-

Hair shaft, Hair bulb

Functions of integumentary system:-

Provides physical protection against bacteria and germs.Protects you from the sun’s ultraviolet (UV) rays and sunburn.Helps you feel heat, cold and detect other sensations.Synthesizes vitamin D.

Hence, integumentary system is more important in body for the regulate temperature and water loss. Thus option B is correct.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is transported, the concentration gradient, and any structures in the cell membrane required to be used.

Answers

Answer:

Osmosis and facilitated diffusion are two forms of passive transport that are integral to cellular transport mechanisms.

Explanation:

Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.

Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.

Across plasma membranes as a form of passive transport in cells, substances move via:

osmosis - water molecules readily pass through the membrane;  the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradientfacilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.

Answers

Answer:

Biology deals with living organisms which show enormous variations and, therefore, numerous exceptions are found.

There are two reasons:

Each organism evolved in a different way to adapt to their environments the best way possible.

It is not really so. There are common rules to biology as in physics, but the problem is we study much more complex systems. More complexity results in more emergent properties, thus they appear to be exceptions.

Biology deals with living organisms which show enormous variations and, therefore, numerous exceptions are found.

justifying it with examples:

1. All living cells have a nucleus except mature red blood cells of mammals.

2. Red blood cells of all mammals are without nucleus except those of camel.

3. Stem is the part of plant above the ground but potato, corm and ginger are underground stems.

4. Blood of all vertebrates is red due to the presence of hemoglobin but a shark, Carcharhinus, has colorless blood.

by the above examples you can see that biology the science of exception.

How do the chromosomes of an offspring cell compare with the chromosomes of the parent cells?

Answers

Answer:

Offspring will usually have half the amount of chromosomes from each parent. For example: Mother Human= 46 Chrom, Father Human= 46 Chrom, Baby Human= 23 Chrom from father and 23 Chrom from mother.

There are just half as many chromosomes. Typically, children inherit half of each parent's chromosomes.

What are chromosomes?

As an illustration, the mother and father of a human have 46 chromosomes each, and the baby has 23 chromosomes from each parent.

The sister chromatids reach their opposing poles at this final stage of mitosis. The cell's tiny nuclear vesicles start to reform around the chromosome cluster at each pole. As the process by which the parent cell transfers its DNA to its two daughter cells, mitosis is a crucial component of cell division.

Homologous chromosomes align in pairs during meiosis. Chromosomes are independent of one another during mitosis.

Therefore,  half as many chromosomes the chromosomes of an offspring cell compare with the chromosomes of the parent cells.

Answers

Answer:

detoxification muscle contraction biosynthesis

Explanation:

ATP, adenosine triphosphate, is a molecule high in chemical energy.  It is made up of a ribose ring, the nitrogenous base adenine, and 3 phosphate groups in a phosphoester linkage at carbon 5

ATP is broken down, losing a phosphate group, and energy is released from breaking the phosphate bond. The other two phosphates in ADP are lined by stable p hosphoanhydride bonds.

[tex]ATP+H_{2}O[/tex] → [tex]ADP+Pi+free \hspace{0.1cm} energy[/tex]

In the body, ATP molecules are used to provide energy for detoxification in forms of active transport; fueling biosynthesis- the modification of different compounds to form macromolecules; and muscle contraction, providing energy to myosin, and braking myosin actin cross-linkages to free myosin for other contractions.

c.) it must be an organism that lived for a very short time period
d.) all of these characters are important fo an index fossil

Answers

Answer:

d.) all of these characters are important fo an index fossil

Explanation:

Organisms have the characteristics to die and their remains form fossils. A fossil is a preserved remain of a previously living organism. Index fossils are fossils used to tell us more about a particular period. However, before the fossil remains of an organism can be used for this purpose, it must have specific characteristics including the following:

- It must be a unique/distinct species

- It must be geographically abundant

- It must live only a short period of time

Based on these above characteristics of a good index fossil, an organism whose remains must form a good index fossil must possess ALL THE MENTIONED CHARACTERISTICS MENTIONED IN THE OPTIONS.

Answer:

d

Explanation:

Index fossils have to be unique and abundant to be easily identified, abundant means it must be around the world. Index fossils usually live for a short period of time. So D is the correct answer.
