In the 1960s the molecular biologist George Streisinger developed the strand- slippage hypothesis. Streisinger noticed that mutations occurred in areas of DNA that contained many repeated sequences. When a strand -slippage occurs, an insertion mutation can result. How does the insertion mutation affect the DNA?
The insertion mutation affects the DNA cause Nitrogenous bases are added to the mix. This is further explained below.
What is a DNA?Generally, DNA is ssimly defined as a molecule found inside cells of a living organism that holds the genetic information.

Suppose you are visiting the equator. It is noon. The Sun is at its highest point in the sky for the day, which is directly over your head. You call a friend on the phone, and she says it is also noon where she is but the Sun is not directly overhead at that location and time. It is a little lower in the sky for her. Compare the longitude and latitude where you are with the longitude and latitude where your friend is. Are they alike or different? How do you know?

Compare how the nervous system and endocrine system work to send messages through the human body.
Answer:
Here is Your answer vote me as brainlist.
Explanation:
One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
The nervous system uses electrical and chemical signals to quickly send messages through the body, while the endocrine system uses hormones to gradually send messages through the bloodstream.
What is nervous and endocrine system?The nervous system uses electrical and chemical signals to transmit information rapidly and directly to specific target cells. This system is composed of neurons, which transmit impulses through the body, and specialized cells called neuroglia, which support and protect the neurons. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord and the PNS includes the nerves that extend out to the rest of the body.
The endocrine system, on the other hand, uses hormones to transmit information more slowly and diffusely throughout the body. Hormones are chemical messengers that are secreted by glands and travel through the bloodstream to target cells. The endocrine system includes a variety of glands, such as the pituitary gland, thyroid gland, and adrenal gland, that produce hormones that regulate various physiological processes, such as growth, metabolism, and reproduction.

This is for my biology class. It is for the osmosis potato lab (Google it if you don't know what it is) and I have to answer this question. I also have to include the words at the bottom. This is really confusing and I would be so happy if someone could please help me with this!
How can a scientist use this lab to determine the amount of solute in an Idaho potato?
Use the following vocabulary words in your final conclusion statement below:
Hypertonic, hypotonic, isotonic, dynamic equilibrium, solute, solvent, osmosis
Explanation:
A scientist can use this experiment to determine the amount of solute in any potato.
hypotonic solution is a relative term. it means when we compare two solutions one of them is considered to be a hypotonic if it's solute concentration is less than the other.
so if the solution has less solute concentration its hypotonic solution and if it has more amount of solute its hypotonic solution. if both solutions have same amount of solute then it will be considered as a isotonic solution. when we separate two solution hypertonic and hypotonic by a semipermeable membrane there occurs diffusion of water molecules from its higher concentration to its lower concentration that is from hypotonic solution to hypertonic solution.
this movement of water molecules is called osmosis. this occurs in order to obtain an dynamic equilibrium between the 2 solutions.
here we take start as solute and water as solvent.
thus when a scientist and potato in a hypotonic solution the water moves inside the potato cavity. the more the transfer of water molecules in the potato cavity the more in the sugar quantity present in the potato. this is because the water will try to obtain a dynamic equilibrium between the two solutions if the sugar quantity in the potato cavity is high then the water molecules needed to dilute that solution will also be high.
in in this way a scientist can determine the amount of salt present in the potato.

Answer:
B. Climate change, species loss, environmental degradation, pollution and environmental Justice .
Explanation:
These are all the current challenges what we usually see on the news or podcast.
Environmental degradation, water shortage, environmental justice, food shortage pollution are the five major current environmental challenges.
What are the environmental issues faced by the humans?Environmental issues are effects of human activity on the biophysical environment, most often of which are harmful effects that cause environmental degradation.
Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas.
Pollution of air, land and water through excessive deforestation, industrialization and overfilling landfills which emits CO2 and adds to greenhouse gas emissions are all topmost causes of these environmental issues.

Answer:
Wildebeest and Zebra.
Explanation:
Wildebeest and Zebra are the hunts which gives huge amount of energy and lowest cost of energy because Wildebeest gives 25000 available energy and 10000 energy cost to hunt and 15000 amount of energy remain while Zebra gives 170,000 while 55000 energy spend on the cost to hunt and 115000 is available energy to the lion that is enough for the lion per day energy requirements.

John lives on a part of Earth where the angle of the sun's rays are very high, and the latitude is low. Which temperatures
does John experience quite often? (1 point)
A. high temperatures
B. moderate temperatures
C. low temperatures
D. temperatures that are sometimes very high and sometimes low
Answer:
The correct option is A
Explanation:
Since the angle of the sun rays are high where John lives, it shows his area is exposed to high radiation of sunlight which is a pointer to high temperature. The question also says his area's latitude is low. Low latitude are those areas close to the equator whose areas are typically warmer than those who live close to the poles. Hence, it can be said that John often experiences high temperature based on the description above.
John often experiences high temperatures (Option A).
The angle of solar radiation is directly associated with the temperature and the localization on the Earth.In regions of low latitude near to the Equator, the angle of the solar radiation is nearly perpendicular or closer to a 90˚ angle and temperatures are warmer.Conversely, in regions of high latitude and near the poles, the angle of solar radiation is smaller and temperatures are colder.In conclusion, John often experiences high temperatures (Option A).
