Answer:
HeLa cells are a great find in the science community and Henrietta Lacks' unique cells are still helping us today. They are perfect for important studies such as cancer, cell biology, genetics, and infectious diseases. Since now we have these unique immortal cells it is quite easy to start any scientific testing on human cells since their is an endless supply. Personally, I believe Henrietta Lacks will live on forever as a hero and mother of modern scientific advancements, since she quite literally, grew all of the modern cell research we have today.

Explain how slumping or soil creep occur. Will hit heart❤️
Answer:
Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock.

Matter is recycled within and between ecosystems through closed loops called biogeochemical cycles. How is this unlike how energy is passed through ecosystems?
Answer:
Energy flows in a one-way direction i.e. unidirectional flow
Explanation:
Matter and energy both pass through an ecosystem as organisms feed on one another. However, as rightly emphasized in this question, matter in form of elements such as water, nitrogen, phosphorus etc. moves in different directions and is recycled within and between ecosystems through closed loops called biogeochemical cycles.
Contrarily to how matter is recycled in an ecosystem i.e. within and between, ENERGY only flows in one direction. Energy enters an ecosystem in form of light (sun) and is passed down from one trophic level to another starting from the producers. This unidirectional pattern of energy flow differentiates energy flow from matter recycling.
Please help me out :( !! Compare and contrast mutualism, commensalism, and parasitism. Use clear and complete sentences.
Answer:
Mutualism is where both organisms benefit, commensalism is where one benefits but the other organism isn’t harmed, and lastly, parasitism is where one organism benefits and the other is harmed. The various species found within a single ecosystem can relate to each other in a variety of ways. The terms mutualism, commensalism, parasitism and symbiosis all refer to the various ways that species within an ecosystem can interact with one another.

A teacher challenges her students to each build a solar oven using common household materials. The students will then test their designs using thermometers. What engineering problem are they trying to solve?
Answer:
Climate issues associated with engineering works
Explanation:
A teacher challenging her students to each build a solar oven using common household materials is highly commendable. The students using this method will help in solving the engineering problem of climate issues.
This will help in the reduction of emission of greenhouse gases which causes global warming. Solar energy on the other hand is renewable and free from emission of such gases.

On one cactus species, the red flowers are dominant over white flowers. If you crossed two heterozygous cacti, what would be the probability of having offspring with red flowers?
Answer:
3/4
Explanation:
This question involves a single gene coding for flower color in cactus plant. The allele for red flowers (R) are dominant over the allele for white flowers (r). This means that a cactus that is heterozygous (Rr) for the Gene will possess a red phenotype.
In this cross, two heterozygous cacti are crossed. The following gametes will be produced by each heterozygous parent: R and r. Using these gametes in a punnet square, the following genotype of offsprings will be produced;
RR, Rr, Rr, and rr
RR, Rr and Rr are Red flowers (3/4)
rr are white flowers (1/4)
Therefore, the probability of having offspring with red flowers is 3/4.

What is the principle of superposition? A. The layers of sediment on the bottom are the oldest. B. All layers of sediment are identical. C. In a given region, all layers of sediment form at the same time. D. The geologic processes of today are very different from those in the past.
Supperposition = the oldest layer in a sequence of undisturbed sedimentary rock is on the bottom
The principle of superposition is the layers of sediment on the bottom are the oldest. Hence option A is correct.
What is superposition?Superposition is defined as a quantum system's capacity to exist in several states simultaneously up until it is measured. It is used to transform any circuit into its Thevenin or Norton equivalent. The theorem can be applied to networks of linear sources, linear passive elements, linear transformers, and linear dependent sources.
The original horizontality concept serves as the foundation for the superposition principle. According to the principle of superposition, each layer of sedimentary rock is older than the one above it and younger than the layer below it in a series of unaltered rocks.
Thus, the principle of superposition is the layers of sediment on the bottom are the oldest. Hence option A is correct.

When you surprised that your mom is on the Hospital and she have a lung cancer stage4 what should you do?
Answer:
what you can
Explanation:
my grandma just got diognosed with two different types of lung cancer, stage 3. Not much you can do but be there for her. One thing that we did for her was make her a cancer/chemo basket after doing research. Apparently it tastes gross so you give them hard candy to suck on and there are certain things like ginger flavored ones or ginger smelling sticks that make you not be nasaus and hats in case she loses her hair (which they said she wouldn't) and a blanket with all of the family on it so she never has to be alone and stuff like that. They're aloud to take one bag to chemo so I would really reccommend doing it. She loved it anyway.

what is budding in plants
Answer:
Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. In the budding process, a bud is taken from one plant and grown on another. Although budding is considered a modern art and science, grafting is not new.

Why is an electromagnet a temporary magnet?
Answer:
An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.
Explanation:
yes
Answer:
The magnetic field generated by the electromagnet only appears when there is an electrical current applied to it. The magnet field will disappear once the electrical current has left.

When a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using
Answer:
ACTIVE TRANSPORT
Explanation:
Generally, the transport of molecules across membranes can either be ACTIVE OR PASSIVE. Active transport are those transport that occurs against a concentration gradient i.e. from an area of low concentration of the substance to an area of high concentration, hence, will require energy input in form of ATP.
On the other hand, passive transport occurs down a concentration gradient and hence do not require energy to take place. Hence, based on the description above, when a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using ACTIVE TRANSPORT.

The number of bison will decrease. c. The bison in the ecosystem will be completely wiped out. d. The number of bison will remain unchanged. Please select the best answer from the choices provided A B C D
Answer:
B
Explanation: I’m just using common sense. If part of the prairie grass is destroyed, that would mean less food for the bison. Which in turn would result in a decrease of Bison?
Answer:
b. the number of bison will decrease.
Explanation:
the wildfire partially destroyed the bison's ecosystem. With less food for the herd, some of them will starve off, decreasing the number of bison there are in the herd.
