Give an example of a trait that is controlled by by more than one gene

Put the steps of the interaction between actin and

Jobisdone [24]

Answer:

Explanation:

The myosin head rotates, causing overlap

with actin.

The myosin head attaches to a binding site

on the actin filament.

The myosin head detaches from one

binding site and reattaches to another.

Does the water cycle, the nitrogen cycle, and the carbon-oxygen cycle play a role in ecosystem balance? Explain.

Anika [276]

Explanation: The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet. Water molecules move between various locations - such as rivers, oceans and the atmosphere - by specific processes. Water can change state. Nitrogen compounds found in cells include proteins. Nitrogen from the air is converted into soluble ions that plant roots can absorb. It forms part of nitrogen compounds in the plants, and is then passed from one organism to the next. It is returned to the atmosphere as nitrogen gas. This is the nitrogen cycle. The carbon-oxygen cycle is the process by which plants use carbon dioxide for respiration during photosynthesis and produce oxygen. During this process, carbon dioxide becomes part of the plant, and when the plant dies in a carbon-rich state it is possible for it to become a fossil fuel.

Explain how the development of the cuticle and the vascular system influenced the evolution of plants on land

Black_prince [1.1K]

<span>When plants moved on the land they had to adapt to new environment and </span>to deal with new <span>problems. The main problem for plants was to figure out how to regulate water loss within the cells. One of the solution was the formation of the waxy covering on top of leaves-cuticle, which evolved on the surface of leaves to reduce water loss. Another problem for plants was to figure out how to obtain resources from soil and air, so they developed vascular tissue to transport water/sugar within the plant.</span>

Which are the basic units of a DNA nucleotide?

ohaa [14]

Answer:

The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
