When does cell differentiation occur?
when cells express different genes
when cells express all genes
when cells express the same gene
when cells do not express genes
Answer:
The answer is when the cell express different genes.
Explanation:
Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.
Answer:
when cells express differnt genes
Explanation:
In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp

According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembrane
components, including the nucleus, endoplasrnic reticulum and qolgi apparatus in what would become eukaryotic cells. The evolution
of endomembrane components provided for compartmentalization in eukaryotes, leading to more efficiency in cell processes. Which
part of the endornembrane system provides a mechanism for transporting proteins from the rough ER to the golgi apparatus?
)
A)
vesicle
B)
lysosome
smooth ER
D)
peroxisome
Hint
Answer:
A) vesicle
Explanation:
As described in this question, the endomembrane system is a system of membrane-bound organelles in eukaryotic cells that functions in the synthesis, packaging, modification, and transportation of lipids and proteins in the cell. The organelles that make up the endomembrane system includes: Secetory Veside, Lysosome, Golgi apparatus, Plasna membrane, endoplasmic reticulum etc.
According to this question, the part of the endornembrane system that provides a mechanism for transporting proteins from the rough ER, which synthesizes it to the golgi apparatus, where it is modified and packaged is VESICLES. Vesicles are membranous cellular organelles that function mainly in the transport of materials e.g proteins
Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determine the phenotypes of the F1 generation resulting from a cross between a heterozygous long legged, weak muscled horse and a heterozygous long legged, strong horse
Answer:
See the answer below
Explanation:
Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).
Heterozygous long leg, weak muscle = Llgg
Heterozygous long leg, strong muscle = LlGg
Llgg x LlGg
Offspring:
2 LLGg - Long leg, strong muscle
4 LlGg - Long leg, strong muscle
2 LLgg - Long leg, weak muscle
4 Llgg - long leg, weak muscle
2 llGg - short leg, strong muscle
2 llgg - short leg, weak muscle
Ratio of offspring with long leg and strong muscle = 6/16 or 3/8
Ratio of offspring with long leg and weak muscle = 6/16 or 3/8
Ratio of offspring with short leg and strong muscle = 2/16 or 1/8
Ratio of offspring with short leg and weak muscle = 2/16 or 1/8

Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.
Explanation:
In simple terms, the term bipedalism refers to a term used to classify organisms that are equipped and use two legs or limp to walk, stand, jump or run.
One other nonprimate animal that is also a biped is the ostrich. When we compare the bipedalism of an ostrich with our (humans) bipedalism we discover that in terms of
Speed; an ostrich can move faster than an average human, reaching speeds of up to 70 km/h (43 mph).
limb length; its limb length can range from 10 to 16 feet (120 inches to 192 inches) which is far greater than the average length of an adult human's legs.

The plant cell wall is made up of cellulose and the bacterial cell wall is made up of peptidoglycan.
What is a cell wall?The cell wall is a protective covering found in plants and bacteria. When bacterial cell attacks the human system lysozymes are some kind of enzymes that degrades the human system.
Penicillin and lysozyme both affect the cell walls of bacteria. When bacteria divide, penicillin weakens their cell walls, causing them to burst and perish from osmotic pressure.
A little enzyme called lysozyme breaks down a bacterium's protective cell wall by attacking it.
Therefore, The plant cell wall is made up of cellulose, and the bacterial cell wall is made up of peptidoglycan.

Describe the nonspecific antimicrobial effects of mucus, lysozyme, and acidic pH. For each of these substances, list where they are found in the body and how they function in fighting pathogens.
Answer: Non specific defence mechanism are the first lines of general defence that aids in preventing entry and minimising further passage of microbes and foreign materials into the body.
Explanation:
The non specific defence mechanisms protects us against any of enormous range of possible dangers using these methods:
--> defence at body surface
--> phagocytosis
--> natural antimicrobial substances
--> the inflammatory response and
--> immunological surveillance.
MUCUS is a slippery substance which covers the luminal surface of the Lungs. It provides defence at the body surfaces. Incase of any inhaled foreign material through the nose into the lungs, it's usually entrapped by the mucus. It is either coughed up or swallowed.
LYSOZYME: This is a protein with antibacterial properties present in granulocytes, tears and sweat. They are natural antimicrobial substances that destroys the cell walls of bacteria leading to its death.
ACIDIC Ph: The presence of acidic natural substances found in the stomach such as the gastric juice or hydrochloric acid, kills the majority of ingested microbes.

Answer:
Revolving nosepiece
Explanation:
The revolving nosepiece (also called the turret) is the part of the microscope we can turn in order to view an object through different objective lenses. Objective lenses, which provide different levels of magnification (usually 4x, 10x, 40x, and 100x), are all attached to the revolving nosepiece. It allows us to switch lenses from those that provide less magnification to those that provide more. This is how we can see more details on an object we're observing.

During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
What is DNA replication?It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.
Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.
The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.
In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.
Thus, the correct statement is the second one, that is, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
