The diagram shows a normal red blood cell and a shrunken red blood cell, both of which are in salt water.

In which direction did the water move to make the red blood cell shrink? Why did water move in that direction?

Answers

The shrunken red blood cell is hypotonic compared to its environment (which is hypertonic), so water will move out of the cell to where there is a higher solute concentration through osmosis.

Remember: Water will always flow to areas to higher solute concentration

Hope that helps! ^_^

Answer:

The red blood cell shrank because water moved out of the cell, which happened because the concentration of salt outside the cell was greater than the concentration of salt inside the cell. Because the salt molecules take up space in the salt water, the concentration of water outside the cell was less than the concentration of water inside the cell. Therefore, water moved out of the cell from the area of high concentration to the area of low concentration, causing the cell to shrink.

Found: A Plant-Eating Spider. Spiders are meat-eaters. Until recently, scientists thought that was true for the roughly 40,000 spider species in the world. Now, researchers have discovered a spider that eats mostly plants. Bagheera kiplingi, a jumping spider, lives in Central America and Mexico. It nests in the leaves of acacia tree. Scientists have long known that ants live in these trees. The ants eat the tree’s little yellow vegetables. But scientists had no idea that the spiders eat the vegetables too. Is competition likely to occur between the Bagheera kiplingi and ants living in acacia trees? Support your answer. *

Answers

Answer:

Yes, competition is likely to occur

Explanation:

Competition is an ecological interaction between organisms of the same or different species, resulting in the detriment of one of the organisms. Competition is generally caused when organisms in an ecosystem occupies the same niche i.e. they rely on the same ecological resource, which could be food, mate, space etc.

The case described in this question involving a Bagheera kiplingi (jumping spider) and acacia ants will likely result in competition because they both occupy the same habitat and feed on the same food (vegetable plant). The two organisms will have to compete for this limited resource, hence, it is regarded as an INTERSPECIFIC COMPETITION because it involves two different organisms.

C. Xylem and phloem fill with ions and organic substances that prevent freezing.
D. Meristems form thick scales to protect next year's buds from cold winter temperatures,

Answers

Answer: Option A, C and D.

Explanation:

Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.

If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures

But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.

Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.

They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.

A group of scientists is trying to bring mammoths back by modifying elephant DNA. The new animals would have a mixture of elephant and mammoth genes. What will be the effect of the new genes?

A. The new genes will produce different proteins.
B. The new genes will prevent DNA replication.
C. The new genes will require gene therapy.
D. The new genes will not have RNA.

The new genes will produce different proteins. Therefore, option (A) is correct.

By modifying the DNA of elephants to include mammoth genes, the scientists aim to introduce genetic variations that were present in the woolly mammoth. These genetic variations would result in the production of different proteins compared to the proteins produced by elephants.

Proteins are essential molecules that perform a wide range of functions within living organisms, including structural support, enzymatic activity, and regulation of biological processes. Therefore, the introduction of new genes from mammoths would lead to the production of different proteins, potentially affecting various traits and characteristics of the modified elephants.

What is soil erosion?

The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.

Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.

Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

Or is Sirius much closer to Earth, giving it the appearance of being brighter? Actually, Sirius is about one hundred times closer to Earth than Rigel. If the two stars were the same distance from Earth, Rigel would appear much brighter. -We use two terms to reference the brightness of a star: absolute magnitude and apparent magnitude. Absolute magnitude is the measure of the light given off by a star, while apparent magnitude refers to the amount of light received on Earth. The color of a star indicates its temperature. Blue-white stars are very hot, while orange-red stars are relatively cool. In the early 1900's Ejnar Hertzsprung and Henry Russell noticed that the higher the temperature of a star, the greater the stars absolute magnitude. They developed a graph that depicts this relationship called the H-R diagram. Most known stars fit into a diagonal band that runs from the upper left to the lower right of the diagram. This diagonal band is called the main sequence. About 90% of all stars are main sequence stars. Most stars are currently classified using the letters O, B, A, F, G, K, and M, where O stars are the hottest and the letter sequence indicates successively cooler stars down to the coolest M class.
