Which plant structure absorbs most of the water and nutrients needed from the soil? tap roots secondary roots root hairs fibrous roots
Answer:
Root hairs

In what way does walking help The environment? How does it make you feel about the state of our environment?
Answer: Walking plays an important role in improving our quality of life because it helps protect and improve the living environment and natural resources. ... Communities designed to be walkable have the potential to reduce air pollution and greenhouse gases because people may choose to walk or bike rather than drive. Walking plays an important role in improving our quality of life because it helps protect and improve the living environment and natural resources. Improving the environment in turn brings added health benefits that come, for example, from cleaner air, less traffic noise and fewer road accidents.
Explanation:
Which type of human population is characterized by the lag phase, being able to raise crops and domesticated animals, but having over farming methods that lead to soil eorion and food shortages?
Answer:
Rural population.
Explanation:
The rural population of humans is characterized by the lag phase because they are linked with farming of crops and domesticated animals. This population is responsible for the soil erosion and food shortages over the country because they are the producers of everything for the food industry. Due to farming methods, soil erosion occurs that leads to the depletion of nutritive part of the soil that causes less productivity of the crop and as a result food shortage occur.

A. reproduce
B. grow and develop
C. respond to the environment
D. obtain energy
Check Answer
Answer:
C Respond to the environment
A mouse running away from the sound of an owl's wings is responding to the environment.
What are living organisms?
The organism which can breathe, reproduce and have the ability to respond to an environment are some of the characteristics of a living organism.
Reproduction is the ability of an organism which gives similar kinds of organisms. Organisms grow and develop through cell division. Cell division is of two types mitosis and meiosis. Mitosis is an equational division.
The organism can respond to the environment. Mouse running away from the sound of an owl's wing is an ability to respond environment. Different organisms can obtain energy from food sources.
Therefore, A mouse running away from the sound of an owl's wings is responding to the environment.

You cross nonpure tall plants (Tt) and produce 200
offspring. Which of the following statements about
the offspring is correct?
A. All of the offspring will definitely be tall.
B. 150 of the offspring will definitely be tall.
C. There is a 75% chance that each offspring
will be tall.
O D. There is a 25% chance that each offspring
will be tall.
Answer:
C is the best answer
Explanation:
the dominate trait is in 3 of the four boxes
There is a 75% chance that each offspring will be tall. Therefore option C is correct.
When you cross non-pure tall plants (Tt), you are dealing with a heterozygous genotype, meaning the plants have one dominant (T) and one recessive (t) allele for the height trait.
The dominant allele (T) is responsible for the tall phenotype, while the recessive allele (t) leads to short plants. In this case, 75% of the offspring will likely receive the dominant allele from at least one parent (Tt or TT) and therefore be tall.
The remaining 25% will inherit the recessive allele from both parents (tt) and be short. This is based on the principles of Mendelian genetics and the Punnett square.
Therefore option C There is a 75% chance that each offspring will be tall is correct.
