How is cell differentiation different than mitosis?

Answers

Answer:Cell differentiation is the process by which cells specialize to achieve their required functions. In order for a cell to differentiate, it will express specific genes. mitosis produces cells that are identical to each other (clones).

Explanation:

Answer:

Though the options aren't presented to the question, I believe the correct answer is: Cell differentiation is different than mitosis, for during cell differentiation, it produces cells with different gene expressions. Meanwhile, during mitosis, it produces clones of the same genes.

The thallus of a mold consists of long, branched, threadlike filaments of cells called _________ that form a tangled mass called a

Answers

Answer:

Hyphae; mycelium.

Explanation:

Fungi can be defined as living microorganisms that are eukaryotic in nature and are able to reproduce using both means of reproduction i.e both asexually and sexually. Also, fungi do not have chlorophyll but are of great importance to the human world both scientifically and practically.

A thallus can be defined as the vegetative or bodily structure of fungi. Thus, the various forms of fungi are;

I. Yeast.

II. Mushroom.

III. Mold.

A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.

The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.

What are hyphae and mycelium in fungi?

Hyphae are the tubular projections of multicellular fungi that form a filamentous network. Fungal hyphae release digestive enzymes in order to absorb nutrients from food sources.

mycelium, the mass of branched, tubular filaments of fungi. The mycelium makes up the thallus, or undifferentiated body, of a typical fungus.

Thus,  hyphae and mycelium is the correct answer.

The artificial cell in the picture below is permeable to monosaccharides but not polysaccharides. Initially, the artificial cell contained a solution of glucose and starch while the beaker was filled with only water. After a period of thirty minutes, the water solution in the beaker tested positive for glucose. What process allowed for this to occur?

Answers

Answer:

Osmosis.

Explanation:

Osmosis is the process which is responsible for the transportation of glucose inside the cell. Osmosis is a process in which micro-molecules such as glucose, ions and gases etc go inside the cell through a semi-permeable membrane. This semi-permeable membrane of the cell only allow monosaccharides but not polysaccharides because monosaccharides is small in size while polysaccharides are larger in size.

C. Gene therapy only focuses on replacing mutated genes.

Explanation:

Hope this helps! Have a good day! :)

The study of animals is called zoology.

The correct answer is C.

Gene therapy is defined as the removal of the mutated gene and placing the correct genes in the DNA to correct the DNA sequence.

Gene therapy is used only to cure genetic diseases like ADA.

Bacteria do not infect the genes of an individual. It targets its immune systems due to which mentioned symptoms are shown.

Explanation:

Why did you flip a coin to determine which allele would be inherited by the offspring?

Answers

You flip a coin because the allele has a 1/2 - 1/2 probability of the two outcomes as is the case when a parent is heterozygous at a locus and so there is a 1/2 - 1/2 probability for each of the two alleles getting passed on to the offspring.

The reason for flipping the coin for measuring the allele should be inherited by the offspring is because of the meiosis process.

What is the meiosis process?

It is the process at which there should be an individual cell that split twice for generating the four cells comprise the half of the original amount of genetic information.

Also, it is to be treated as the s-ex cells like sperm in males, and eggs in females.

Moreover, the DNA should be received.

- Isotonic solution
- hypertonic solution
- hypotonic solution


Help!! Plz

Answers

Answer:

- hypotonic solution, hypertonic solution, isotonic solution

Explanation:

When an animal cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.If an animal cell is placed in a hypertonic environment, water will leave the cell, and the cell will shrink.Our cells in our bodies are made of isotonic solutions. See Khan Academy's "Osmosis and tonicity" article for a further explanation!
1) hypotonic (the water concentration is too low for animal cells to survive, outside of the cell has less water than inside the cell so the water from inside of the cell goes to the area of lower concentration, which in this case is outdid of the cell so the cell shrivels)
2) hypertonic (the water concentration is too height for animal cells to survive, the water fills the cell too fast and the cell bursts)
3) isotonic (this is the perfect condition, cells can survive here)

a. A mountain range in Africa lines up with a mountain range in South Africa
b. All of the continents have mountain ranges along the ocean shoreline
c. Each continent shows evidence that glaciers once covered the land
d. Major rivers in all continents flow to the oceans

Answers

A, because mountains are caused by plates pushing together, and the mountains lining up is a result of that.

The evidence from landforms that supports the theory of continental drift and the theory of plate tectonics is that all of the continents have mountain ranges along the ocean shoreline. Thus, the correct option for this question is B.

What is the theory of continental drift?

The theory of continental drift may be characterized as the movement of the Earth's continents relative to each other, thereby appearing to drift together across the oceanic bed. It is the hypothesis that the Earth's continents have moved over geologic time relative to each other.

The processes of seafloor spreading, rift valley formation, and subduction are some of the major causes of this continental drift. These processes were the main geologic forces behind what Wegener recognized as continental drift.

The movements of the earth's plate form the landforms that are responsible for creating boundaries of the continents that range along the ocean shoreline.

Therefore, the correct option for this question is B.
