Dialysis tubing simulated a cell membrane that leads to entering of micromolecules.
Dialysis tubing simulated a cell membrane which is permeable to small molecules means allows to enter small molecules such as oxygen, glucose and water molecules etc but not to larger molecules to enter the cell due to its large size and the holes in the cell membrane are smaller. Due to small size of materials or molecules, they can easily enter inside and comes outside because the size of the hole is bigger than their size so that's why it is concluded that micromolecules are stimulated by the placing of the dialysis tubing in rice.

A scientist is studying some developing eggs from an ocean sample. The early embryos have divided only a few times, and all cells look identical. When the scientist carefully removes half the cells from an embryo, both clumps of cells are able to complete development, forming twins. The eggs can be identified as cnidarians. crustaceans. protostomes. deuterostomes. echinoderms.
Answer:
The correct answer is - deuterostomes.
Explanation:
Duetorstomes eggs ,During embryonic development the zygote undergoes cleavage. Cleavage results is slitting into multiple cells where ease cell has the ability to develop into a complete embryo when isolated.
Out of 800 progeny of a three-point testcross (testcross for a heterozygote for all three loci) there were 16 double crossovers, whereas 80 had been expected on the basis of no interference (Hint: each double CO produces two double recombinants). The interference is:_________

Pls help me
Answer:
it was
Explanation:
The correct answer is B. Cellular respiration supplies energy to cells, but photosynthesis does not.
Which statement is correct?Photosynthesis and cellular respiration are two distinct processes that occur in living organisms, particularly plants. Here's a brief explanation of each process:
Photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. It occurs in the chloroplasts of plant cells. The process involves the absorption of carbon dioxide (CO2) and the release of oxygen (O2) as a byproduct. Photosynthesis is responsible for converting solar energy into stored chemical energy.
Cellular respiration: Cellular respiration is the process by which cells break down glucose and other organic molecules to release energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells, including plant cells. During cellular respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced as waste products. This process provides energy for various cellular activities.
Given the descriptions above, option B is the correct statement. Cellular respiration supplies energy to cells through the breakdown of glucose, while photosynthesis is the process that converts light energy into chemical energy and produces glucose.

In working with Drosphilia it is common to use a balancer stock to maintain mutations of interest. The balancer chromosomes are generally carrying multiple inversions on them. What effect would the inversions have on meiosis
Answer:
Fusion or pairing does not occur.
Explanation:
Inversions mutation leads to lowered fertility due to production of unbalanced gametes in the meiosis cell division. Chromosome inversions have no effect on mitosis, but they has affect meiosis because inversions changes the gametes which is only present in meiosis. If an inversion present is in the heterozygous condition, pairing of chromosomes cannot occur in a simple linear fashion due to change of sizes. But if the inverted chromosome segment has the proper size so it can paired with each other.
Why are all viruses obligate parasites?
Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.

A single division occurs, separating sister chromatids Homologous chromosomes pair up and form chiasmata d. Daughter cells contain recombinant chromosomes e. Process starts with a diploid cell Homologous pairs of chromosomes line up on the metaphase plate f. End result is four haploid cells that are genetically different from each other and the parent cell g. Duplicated chromosomes line up Individually on the metaphase plate in a diploid cel h. End result is two diploid cells that are genetically identical to each other and the parent cell Mitosis Melosis Both mitosis and meiosis
Answer:
Mitosis:
A single division occurs, separating sister chromatids
End result is two diploid cells that are genetically identical to each other and the parent cell
Meiosis:
The first division separates homologous pairs; the second division separates sister chromatids
Homologous chromosomes pair up and form chiasmata
Homologous pairs of chromosomes line up on the metaphase plate
Daughter cells contain recombinant chromosomes
End result is four haploid cells that are genetically different from each other and the parent cell
Mitosis and Meiosis:
Chromosomes duplicate during interphase
Process starts with a diploid cell
Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell
Explanation:
Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.
A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.
Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis. During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.
Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.

The difference between a pH of 5 and a pH of 8 is
Group of answer choices
A) 3x
B) 30x
C) 100x
D) 1,000x
Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the H+ concentration in acidity/basicity. The more H + ions found in solution, the more acidic the substance is as acids donate H + ions.
You can calculate the concentration of H + from the pH and the equation
p H = − log [ H + ]
arrange again
[ H + ] = 10 − p H
So for a pH of 8, we get [ H + ] = 10 ^− 8
For a pH of 5, we get [ H + ] = 10^ − 5
10 ^−5 /10 ^− 8= 10 ^3
= 1000

Answer:
cryosphere → glaciers, ice caps, ice bergs
atmosphere → air surrounding earth
biosphere → all of Earth's living things
geosphere → Earth's interior, rocks, minerals, and landforms
hydrosphere → oceans, lakes, rivers, streams, and groundwater
Explanation:
The above are properly matched.
Cryosphere is known as part of the earth were water is in solid form. This has to do with glaciers, ice, ice bergs, etc.
Atmosphere has to do with the part of the earth that is gaseous. This has to do with the air found on earth.
Biosphere is the living part of the earth. All things are found in the biosphere.
Geosphere is known to be earth itself which is made up of the landforms, rocks, minerals, earth's interior, etc.
Hydrosphere has to do with the liquid part of the earth. It has to do with the water bodies.

The movement of DNA or RNA in gel electrophoresis is often a matter of molecular weight alone. Which of the following molecular parameters usually influence the movement of protein?
a. weight, charge, or shape
b. only charge
c. only shape
d. only weight and shape
d. only weight
Answer:
a. weight, charge, or shape
Explanation:
Gel electrophoresis is a molecular technique used to separate samples of DNA, RNA and proteins on the basis of charge, mass or size. The molecules migrate through a gel matrix supplied with electric current on the basis of size or charge. For example, +ve charge molecules move towards the -ve end of the matrix or smaller molecules move faster.
According to this question, the movement of DNA or RNA in gel electrophoresis is often a matter of molecular weight (size) alone. However, that of protein involves a combination of weight, charge, or shape.
