Answer:
The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.
Explanation:
The concentration of CaCl2- = 200mM
CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity
The concentration of glucose = 15 mM
So, the osmolarity of solution 1 would be:
3 × 200 + 15= 615 mM
Similarly, the osmolarity of the second solution would be
The concentration of NaCl = 140 mM
The concentration of glucose = 150 mM
NaCl dissociates in the two different ions in a solution and each has the same osmolarity
140×2+ 150= 430 mM
The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.
The bacteria we are growing contain both chromosomal DNA and plasmid DNA. Both are circular, but they are different. In 3-5 sentences, discuss at least 3 differences between the chromosomal DNA and plasmid DNA found in our bacterial cells.
Answer:
Please find the explanation of the differences between chromosomal DNA and plasmid DNA below
Explanation:
As stated in this question, a bacteria cell contains both chromosomal or genomic DNA and an extra chromosomal DNA called PLASMID. They are both circular in shape but are different from one another in the following ways:
- Chromosomal DNA is larger in appearance than the plasmid DNA, hence, they differ in terms of size.
- Chromosomal DNA encodes all the information in the genome of the bacterial cell necessary for their growth and development while plasmid DNA encodes few additional beneficial characteristics such as antibiotic resistance, virulence etc.
- Chromosomal DNA is wrapped around histone proteins to form the chromosome structure but plasmid DNA is naked and not wrapped around histone proteins.

Use the ideas of natural selection to suggest how woolly mammoths may have developed..
Science !!
PICTURE BELOW
Answer:
thats crazyyyy
Explanation:
Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.
The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.
The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.
For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.

What effect does dietary protein have on the body?
Answer:
Even mostly or entirely plant-based diets can be high in protein. Protein is an essential part of a healthy diet. It helps to build and repair muscle, organs, and bones. High-protein diets have also been shown to be helpful with reducing fat, losing weight, increasing satiety, or a feeling of fullness, and retaining muscle.
g It has been proposed that integrin proteins undergo conformational changes when they bind to small molecules diffusing into the extracellular matrix. Because integrins are transmembrane proteins, a change in their conformation can be transmitted across the membrane to the portion of the protein that interacts with intracellular structures. What biological role does this allow integrins to play in a cell's function within a multicellular organism
Answer:
Cell-cell communication
Explanation:
Integrins are heterodimeric transmembrane receptors that facilitate the adhesion to the cell-extracellular matrix by attaching the cytoskeleton to this matrix. Moreover, integrins also help the cells bind with other cells. Integrins are responsible for the communication between cells and thus control tissue structure. These receptors are responsible for the attachment of fibroblasts to collagen, as well as the attachment of fibroblasts to fibronectin. It is also important to highlight that the binding of integrins with their corresponding ligands activates signaling pathways that control diverse cellular processes including, among others, cell growth, cell development, cell migration, phagocytosis, etc.

HELP PLS Danielle lives with her family on a farm. In school, she has been learning about the nitrogen cycle in science class. She knows that her father spread a nitrogen-based fertilizer on a patch of grass recently where the cows graze in the field. Why was it necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass?
a.because nitrogen can only be “fixed” by lightning
b.because there are no decomposers on the farm
c.because bacteria released all of the nitrogen into the air
d.because plants cannot use “free” nitrogen
It necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass - d. because plants cannot use “free” nitrogen.
Nitrogen cycle is the series of processes where nitrogen converts into its compound move through the environment and in living organisms.
The processes here include fixation, ammonification, nitrification and denitrification.Majority of Earth's atmosphere is nitrogen.Nitrogen fixation is the process allows free nitrogen to available for plants.Plants can not use free nitrogen their for they require fixation and nitrogen fixating bacteria in nature.nitrogen fertilizers provide nitrogen for plants in soil therefore it necessary to add a nitrogen-based fertilizer to the soil.Thus, It necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass - d. because plants cannot use “free” nitrogen.

Vitamin K is a fat soluble vitamin that exists in two natural forms: phytonadione (K1: fye toe" na dye' one) which is derived from plant sources and menadione (K2: men" a dye’ one) which is derived from bacterial sources. Vitamin K is a cofactor in the photosynthetic electron-transport system in green plants, which are the major dietary source of vitamin K for humans. High levels of vitamin K1 are found in leafy green vegetables while vitamin K2 is found in meat, milk and butter. In humans, vitamin K is an essential cofactor in the gamma-carboxylation of glutamate residues of several clotting factors and anticoagulant proteins. Hope this helps!

A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.
A hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic
if you place a cell in a hypertonic solution, the cell shrinksit loses water as due to osmosis water moves from a higher concentration inside the cell to a lower concentration outsideThe water will move out of the cell to try to equalize.Thus, A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.
