Answer:
b.
Explanation:
They used Franklin's photo to determine that DNA was a double helix.
Answer:
- to have cell walls made of chitin
- eukaryotic heterotrophs
Explanation:
Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.
The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.
Kingdoms include different phyla closely related.
The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.
All the members of the kingdom
-
Lack mobility, growing on the ground, organic matter, or other surfaces.
- They all have a rigid cell wall composed of chitin.
- They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.
- Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.
- Reproduction is by spores, which are resistant to adverse environmental conditions.
Answer:
We (humans) remove nutrients from the land and discharge them into aquatic environments. On one hand, this leads to soil depletion on the land, and on the other hand, an over abundance of the nutrients and pollution of water sources.
Explanation:
Answer: Animals undergoing examination should be restrained with just enough force to calm them and keep them still so that the veterinarian can provide proper veterinary care. Each animal's restraint needs will be different and dependent on their behaviors and anatomies.
The presence of over 700 genes involved in height determination is an example of a polygenic trait.
<h3>What is a polygenic trait?</h3>
A polygenic trait refers to a trait that is determined by multiple genes rather than by only one gene. This is opposite to a monogenic trait that is determined by only one gene.
<h3>What are some examples of polygenic traits?</h3>
In humans, some examples of traits that are determined by multiple genes are:
- Height
- Hair color
- Skin color
Based on this, heigh is a polygenic trait.
