What three problems had to be solved before plants could be well adapted to life on land ? What was the evolutionary solution to each of these problems?
Answer:
Explanation:
Avoiding dehydration. Plants on land would have developed roots to acquire water from the soil. They also developed stomata ( by difinition: Stomata permit the absorption of carbon dioxide necessary for photosynthesis from the air, as well as the removal of excess oxygen) on the underside of their leaves to reduce water loss. Adaptation to arid environments involved waxy coats and fleshy leaves for water storage.*biology

Answer:
Answer to 1: a black hole is a tremendous amount of matter crammed into a very small (zero) amount of space. Answer to 2: the top of your head would feel so much more gravitational pull than the tips of your toes that you would be stretched, longer and longer Answer to 3: A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. because no light can get out, people can't see black holes Answer to 4: stellar, intermediate, supermassive, and miniature. Answer to 5: the asymmetry of bright and dark sections of the ring are caused by the Doppler effect as the matter is coming toward Earth (brighter) or receding (dimmer).

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?
Answer:
The bacteria forms new kind of cells to adapt to a new environment. This adaptation is under tight genetic control, involving the expression of multiple genes.
the bacteria need to adjust their enzyme levels in order to quickly benefit from the nutrient mix that is currently available in the surrounding.
If the living environment undergoes a sudden change, the bacterium's own production of proteins has to fulfill these changes in an effective way.
How does a scientist compare the age of a rock with other rocks
Answer:
They can use radioactive dating
Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

Which best describes the function of the part labeled b? carries all the genetic information of the organism provides all of the master instructions of the cell joins sister chromatids codes for a specific trait
Answer:
carries all the genetic information of the organism
Explanation:
Genes are located on many chromosomes. In other words, a particular section of the genome is located on each chromosome.
What are the main role of chromosome in the information?The primary function of the chromosomes is to transfer DNA, the fundamental component of genetic material. The genetic instructions for numerous biological functions are encoded in DNA.
Chromosomes, which resemble threads, are located in the nucleus of both animal and plant cells.Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
These processes are necessary for the development, maintenance, and procreation of the organisms.Proteins like histones, which protect the chromosomes.
Therefore, DNA is passed down from parents to children and contains the precise instructions that give each sort of living thing its individuality.

Please help im being timed Should a marine scientist automatically assume a study from a corporation has bias? Why or why not?
Answer:
Yes
Explanation:
It's safe to assume this because it is the best way to make sure that your sources are reliable and valid.
A marine scientist should not automatically assume that a study from a corporation has bias. This is because there are various factors that could affect the findings of a study, and not all studies from corporations are biased.
What is bias?Bias is the tendency to favor one view, person, or result over another, especially in an unfair or prejudiced way. It can be conscious or unconscious, and it can manifest itself in different ways.
When conducting scientific research, bias is a problem because it can lead to flawed conclusions, which can have negative consequences for the environment or the public.
A marine scientist should carefully evaluate any study, regardless of the source, to determine if it is scientifically rigorous and unbiased. They should look for potential conflicts of interest, analyze the methodology used, and scrutinize the data and results presented.
If they detect any signs of bias, they should report them and try to work with the researchers to correct them or address any concerns. However, if they find that the study is scientifically sound and unbiased, they should acknowledge and use the results in their own work, since these can be valuable for the scientific community.
In conclusion, while it is important to be vigilant against bias in scientific research, a marine scientist should not automatically assume that a study from a corporation is biased. Instead, they should carefully evaluate the study to determine its scientific merits and potential biases, and report their findings accordingly.

Which features are usually associated with karst topography?
A. Caves and sinkholes
B. Lakes and wetlands
C. Mountains and valleys
D. Plains and plateaus
A. Caves and sinkholes are usually associated with karst topography.
How Karst topography is formed?Karst topography is formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. As water flows through these rocks, it dissolves them, creating underground cavities and channels.
Over time, the ground above these cavities can sink, forming sinkholes. The dissolved rock can also create caves and other unique features such as natural bridges, disappearing streams, and springs.
Karst topography is a type of landscape that is characterized by distinctive landforms and features that are formed by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum.
These rocks are highly susceptible to chemical weathering, which is the breakdown of rocks and minerals through chemical reactions. The process of chemical weathering dissolves the rocks, leaving behind distinctive landforms and features.
Overall, karst topography is a unique and fascinating landscape that is created by the dissolution of soluble rocks. The distinctive features of karst topography, including caves, sinkholes, natural bridges, disappearing streams, and springs, make it a popular area for exploration and study.
However, the hazards associated with sinkholes and other features of karst topography also make it important to be aware of the risks when living or traveling in these areas.

What is independent variable?The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.
The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.
The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.

which of the following correctly orders the zone of depths in a lake from shallowest to deepest?
A. profundal, littoral, limnetic
B. Littoral, profundal, limnetic
C. Limnetic, littoral, profundal
D. Littoral, limnetic, profundal
Answer:
D. Littoral, limnetic, profundal
Explanation:
The level of water bodies like ponds and lakes are divided into different zones from top to bottom and side to side. The Littoral zone starts from the dry land that moves in a downward direction towards the open water. There are lots of nutrients and minerals in this zone. Insects, small fish, and zooplankton live in this zone. The limnetic zone starts after the littoral zone ends. It is the part of the pond which receives the sunlight. Algae and other plants live in this zone because the level of oxygen is high in this area. The profundal zone is located where the sunlight does not reach. The population of fish is very low in this zone.
