1. Which of these physical trait(s) did
scientists claim were connected to
certain behavioral trait(s)?
Answer:
It turns out that the body color and wing length genes are linked, which means they are located very close to each other on the same chromosome. In addition, if two genes are linked in this way, then gametes are more likely to contain specific allele combinations.

The variations in a population make no difference in terms of reproductive success.The variations in a population make no difference in terms of reproductive success.
Answer:
.Variation within a population is heritable. Populations experience competition for resources.
Explanation:
Variation exist among individual, and this makes individual unique. Variation in shape,size,color exist in an organism.
Traits or character can be inherited from parents which means it can be transfer from one person or individual to another.
Each organism posses different traits for survival, some traits are presents as to better help some organism adapt to their environment.

The amount of water circulating around the planet is always
A. fixed (staying the same.)
B. decreasing.
C. increasing.
Answer:
The answer would be fixed.
Explanation:
According to the law of conservation of energy, energy cannot be created or destroyed. I can safely assume it is the same with the flow of water on the Earth’s surface. Also, according to what is known about the water cycle, it is impossible for water to simply disappear from the face of the Earth.
Let me know if I am correct! :>
Answer:
A. fixed (staying the same.)
Explanation:
The amount of water circulating around the planet is always fixed (staying the same.)
Question 21 (1 point) Sustainable use is often defined as the use of natural resources at a rate that meets the needs of the present human population but which also allows future generations to use the resource to meet their needs. Which of these BEST illustrates the concept of sustainable use? A fishing trawler uses a large net to catch a school of small fish A logging company reseeds and replants in a forested area after cutting down trees for timber Crops are rotated in a farmer's field to maximize grain yields Coal is mined using underground tunnels to avoid the destruction of surface soils by strip mining
Answer:
A logging company reseeds and replants in a forested area after cutting down trees for timber
Explanation:
Answer:
Sustainability is the capacity to endure in a relatively ongoing way across various domains of life.[1] In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.[2][failed verification] For many in the field, sustainability is defined through the following interconnected domains or pillars: environmental, economic and social,[3] which according to Fritjof Capra,[4] is based on the principles of systems thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political.[5][6] According to Our Common Future, sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."[7][8] Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (seeing development as inherently unsustainable).[9]

WILL GIVE BRAINLIST!!!!! what are 3 ways that animals and plants can erode rocks in different locations?
Answer:
Hope this Helped :)
Explanation:
1.Biological weathering-Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.
2.Plants change Earth’s surface through weathering and erosion.They take minerals from the rock. This is a type of weathering, and it weakens the rock. Eventually the surface of the rock starts to break down and become soil.
3.As larger plants like trees start to grow in a rocky area, their roots
grow into the small cracks in the rock. Slowly, as the tree grows, its roots break the rock apart. This forms more soil and makes it easier for other plants to grow there as well.
4.When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is more likely to be eroded by wind and water.

A doctor examines a patient who has high blood pressure and atherosclerosis in the coronary artery. What medical condition connected to blood flow is most likely to affect this patient in the future?
A. The patient may develop headaches and confusion due to cancer in the brain caused by years of low levels of oxygen supplied to the brain.
B. The patient may develop stiff joints and chest pains from the high blood pressure applied to the muscle and joint tissues of the body.
C. The patient may show signs of confusion, weakness, and partial paralysis due to high blood pressure when the plaque dislodges and blocks blood flow to the brain.
D. The patient may suffer a heart attack because of the reduction in blood flow to the muscles due to severe plaque build-up in the coronary artery.
