Why does the earth have a magnetic field?
Answer:
QUESTION:
Why does the earth have a magnetic field?
ANSWER:
The magnetic field of Earth is caused by currents of electricity that flow in the molten core. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates. The powerful magnetic field passes out through the core of the earth, passes through the crust, and enters space.

Cell division is not only for generating copy of DNA . Why ?
Answer:
sorry don't know sorry
Explanation:
ok
Answer: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. ... Healthy cells can perform DNA replication with almost absolute accuracy most of the time.
What macromolecules are capable of self-replication?
Proteins
RNA and DNA
Polysaccharides
Fats and triglycerides
Answer:
B

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.
Answer: I had the same problem in one of my exams. I think the answer is "the ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
Explanation:
I chose this because it seems like the most logical explanation.
"The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.
What is biodiversity?Biodiversity is considered as the variety of living things found in the various habitats, such as terrestrial, marine, and desert ones, as well as the ecological groups to which they belong.
The variety of the creatures present in an ecosystem, as well as their relative abundances, is referred to as biodiversity. It also depicts the various stages of organism organization.
In ecosystem there are thirteen different grass species present and in ecosystem Y 1 species of grass present, that is, ecosystem X has a greater amount of biodiversity. So, during the drought, the bison in ecosystem X are better able to survive.
Therefore, "The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

Which statements describe hormones in plants? Check all that apply.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.
(i know that the first 4 are not right and neither are A, B, and D (1, 2, 4)
Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.
Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution?
A. The similarities suggest that chickens and humans are the direct descendants of modern-day fish with tails and gill slits.
B. The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop.
C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species.
D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slits.

Based on one of the four scenarios below, create an explanation for how Natural selection works, incorporating all of the 5 concepts that contribute to it.
1. Galapgos Darwin's Finches
2. Caribbean Anoles
3. Giraffe lab
4. In a field that is mostly green because of regular rain, the coat color of the mice species that lives there is mostly dark colors. Over a period of 10 years, there is a drought, and the grass has a lot more dead material, making the field have a much lighter over all color. What happens to the population of mice (coat colors) and why?
5. Make up your own scenario (tell me it) and then describe how natural selection would take place with changes.
Answer:
Population of mice having dark coat colors decreases by changing of features of natural selection.
Explanation:
The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.

Why can enzymes be used over and over again
Answer:
Enzymes are biological catalysts. They catalyse biochemical reactions. They increase the rate of reaction. They do not chemically react or get utilised in the reaction so enzymes can be used over and over again.
For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. View Available Hint(s) For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. decreases increases in square patches and decreases in circular patches increases remains unchanged increases in circular patches and decreases in square patches
Answer:
increases
Explanation:
Habitat is defined as a particular environment where a group of organisms normally lives. Some examples of habitat include, among others, forests, deserts, lakes, grasslands, etc. Moreover, an edge habitat refers to a habitat area that is in contact with another. This part of the habitat has ecological importance because it is used by many species in order to find food, refuge and rest. In the question above, it is expected that a greater number of smaller habitats increase edge habitat surface area when compared to the interior habitat area. The ratio between the edge habitat surface area and total habitat area may have a huge impact on entire ecosystems.
Mannitol is a drug that temporarily disrupts tight junctions. This drug is often added to medications that need to get into the extra-cellular fluid of the brain because it will make the capillaries of the ________ more permeable to larger molecules. Mannitol is a drug that temporarily disrupts tight junctions. This drug is often added to medications that need to get into the extra-cellular fluid of the brain because it will make the capillaries of the ________ more permeable to larger molecules. blood-brain barrier meninges ventricles arachnoid villi
Answer:
Mannitol is a drug that temporarily disrupts tight junctions. This drug is often added to medications that need to get into the extra-cellular fluid of the brain because it will make the capillaries of the blood-brain barrier more permeable to larger molecules.
Explanation:
The blood-brain barrier's components are endothelial cells, basement membrane, pericytes, and astrocyte endfeet. The gaps between endothelial cells are small. As a consequence, they form tight junctions that allow the passage of specific and small molecules. In this way, the barrier stops any pathogen from entering the brain. That is to say, that the blood-brain barrier is extremely selective; therefore, medications will not pass through it, so to allow the medicine to enter the brain extracellular fluid, the tight junctions of the endothelial tissue must be disrupted with mannitol.
