Give an example of how a random mutation in an organism could give it an environmental edge over other members of its species.
Do changes in the environment CAUSE mutations or are they already present in the gene pool of a population? Explain.
Answers
Answer: The mutation could cause it to adapt to the environment better, pick up food better, or even become almost totally different to the others because of how different it is. changes in the environment determines which organism lives. Some mutations seem to happen spontaneously without any outside influence. They can occur when mistakes are made during DNA replication or transcription. Other mutations are caused by environmental factors. Anything in the environment that can cause a mutation is known as a mutagen. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. ... Mutations contribute to genetic variation within species.

The Nervous System is one of the first systems to develop during the embryonic period. Why do you think this is?
Answers
The process of neurulation, which takes place between weeks three following conception, allows the embryo to form the components that will one day become the nervous system. It's important to regulate body functions.
What is embryonic nervous system?The neural crest gives rise to the development of structures in the periphery. At this stage, the early nervous system resembles nothing more than a straightforward tube. It begins from the front of the embryo and continues all the way around to the back. Beginning at day 25, the anterior end will develop into the brain, while the posterior portion will develop into the spinal cord.
The brain is the organ that is responsible for controlling every function of the body. The brain is connected to the rest of the body through the spinal cord, which travels down the back. It contains nerves that are similar to threads and branch out to every organ and area of the body. Messages are transmitted to and from the brain via this network of nerves, which connects the brain to various regions of the body.

many species of animals carry an allele for albinism (lack of pigmentation). Albinos are usually pale or white in color. explain why the allele for albinism is present at la lower frequency than the allele for having pigments. what conditions would be necessary for the albino allele to be more frequent?
Answers
Answer: breeding an albino with an albino and let the babies lose and repeat
Explanation:
The allele for albinism is present at a lower frequency because it is not adaptive for most of the environments where humans live.
What is an allele?An allele is a gene variant that confers a certain fitness to an individual depending on the environment where this organism lives.
Adaptive alleles are in high frequency because they confer an adaptive advantage.Non-adaptive alleles are present in low frequency because they do not confer an advantage.In conclusion, the allele for albinism is present at a lower frequency because it is not adaptive.

Composite volcanoes are explosive, towering giants. Shield volcanoes quietly produce broad, massive structures through lava flows. Cinder cone volcanoes are the smallest and simplest, but still pack a volcanic punch. A caldera is a large depression formed when a volcano erupts and collapses. Lava plateaus are extensive areas of flood basalt which are formed by the extensive eruption of basaltic lava over a large area.

Use the drawing tool to modify the model, showing the direction of prevailing winds in the Northern Hemisphere and convection currents. Label hot and cold air on your convection currents.
Answers
Answer:
Image down below will be correct.
Explanation:
The direction of prevailing winds and convection currents in the Northern Hemisphere and how to label them.
What is westerlies?Prevailing winds in the Northern Hemisphere generally blow from west to east due to the Coriolis effect. This means that winds move clockwise around areas of high pressure and counterclockwise around areas of low pressure. The prevailing winds are known as the westerlies.
Convection currents in the Northern Hemisphere are driven by temperature differences between the equator and the poles. Warm air rises at the equator and moves towards the poles, while cold air sinks at the poles and moves towards the equator.
This creates a convection current that moves from the equator to the poles in the upper atmosphere and from the poles to the equator in the lower atmosphere.
To label hot and cold air on your convection currents, you can draw arrows to show the direction of movement and label them accordingly. Hot air rises at the equator and cold air sinks at the poles, so you can label the arrows with "hot" and "cold" respectively.

2. Describe how
removing an

Answers
Answer:
1. A food chain is a single pathway connecting a producer with several levels of consumers. In a typical marine food chain, dinoflagellates convert energy from sunlight into food through photosynthesis and store it in their tissues.
2. They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.
have a good day!
The flow of energy in a marine food web include the following:
Plankton⇒shrimp⇒ salmon⇒ seals⇒ whales
What is a food web?A food web comprises of food chains which are interconnected and also
explains the flow of energy between organisms in the ecosystem.
In the marine ecosystem, the plankton which are plants are the primary
producers while the whales are the tertiary/quaternary consumers as they
are at the top of the web.
Removing an organism from a food web can impact the entire ecosystem
by reducing the number of organisms and options available for food. It can
increase or decrease the population of organisms which they have direct

Answers
Answer:
There are 11 in total systems in human body containing their specific organs hence are called as organ systems.
Explanation:
These are muscular system, digestive system, integumentary system, skeletal system, circulatory system, respiratory system, lymphatic system, endocrine system, excretory system and reproductive system. All these systems contain their specific organs. However, these systems are somehow related to each other.
Hope this helps you!
.
The muscular system, in vertebrates, is controlled through the nervous system, although some muscles, like cardiac muscle & muscles in stomach walls, can be completely autonomous.
Digestive system breakdown the food and absorb nutrients from it.
Integumentary system act as a barrier, protect the inner stuff of body, regulate body temperature and also eliminate waste(e.g sweat).
Skeletal system supports the body and protect the internal organs(e.g rib cage protect heart and lungs).
Circulatory system help to transfer blood, nutrients, hormones, oxygen and other gases to and from different body parts.
