The answer is DNA (Deoxyribonucleic acid).
DNA is the molecule present in the nucleus of our cells that has all of our genetic instructions. This molecule consists of a double-helix ribbon composed of nucleotides that will dictate most of our traits. I say 'most' because some traits result from an interaction with the environment.
During sexual reproduction, DNA from our parents is inherited to us. That's why we have physical similarities and also in personality to our parents.
production of body heat: The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulations. Hence, production of body heat is not a function of the skeletal system.
The question is incomplete. The complete question is:
We would expect the greatest difference in plant health between two groups of plants of the same species, one group with mycorrhizae and one group without mycorrhizae, in an environment _____.
A) where nitrogen-fixing bacteria are abundant.
B) that has soil with poor drainage.
C) that has hot summers and cold winters.
D) in which the soil is relatively deficient in mineral nutrients.
E) that is near a body of water, such as a pond or river.
Answer:
D) in which the soil is relatively deficient in mineral nutrients.
Explanation:
Mycorrhizae are mutualistic associations between fungi and the roots of plants. The fungus grows around and into the root and into the surrounding soil. The fungus absorbs essential minerals, especially phosphorus, from the soil for the plant. The plant provides the organic nutrients produced by photosynthesis to the fungus. Therefore, the plants with mycorrhizae exhibit better growth in mineral deficient soil than the plants without mycorrhizae.
Answer:
Explanation:
determines the traits of offspring resulting from sexual reproduction
Explanation:
Both the endocrine and nervous systems use chemical signals to communicate and regulate the body’s physiology. The endocrine system releases hormones that act on target cells to regulate development, growth, energy metabolism, reproduction, and many behaviors. The nervous system releases neurotransmitters or neurohormones that regulate neurons, muscle cells, and endocrine cells. Because the neurons can regulate the release of hormones, the nervous and endocrine systems work in a coordinated manner to regulate the body’s physiology.
