In an area of East Texas, the most intense competition would most likely occur between white-tailed deer and
A. brown bears
B. squirrels
C. other white-tailed deer
D. coyotes
Given what we know, we can confirm that the most intense competition would most likely occur between white-tailed deer and other white-tailed deer.
Why would white-tailed deer most likely compete with themselves?This has to do with food sources. Of the many animals listed, none of them share a food source with the white-tailed deer. The deer are herbivores that feed primarily on grass and shrubs. The bears and coyotes are carnivores that feed on other animals such as the deer themselves. While squirrels are herbivores but do not compete with the deer for food.
Therefore, given that other deer are the only animals listed that are after the same food source, we can confirm that the most intense competition would most likely occur between white-tailed deer and other white-tailed deer.

What type of epithelial tissue is found in the proximal and distal convoluted tubules
Answer:
simple cuboidal epithelium
Explanation:
The type of epithelial tissue found in the proximal and distal convoluted tubules is the simple cuboidal epithelium.
What do you mean by Epithelial tissues?The epithelial tissues may be defined as a kind of body tissue that constitutes the surface on all internal and external surfaces of your body, lines body cavities and hollow organs, and is the major tissue in glands.
Proximal convoluted tubules (PCT) are formed by the simple cuboidal tissues in a brush-like border of microvilli to enhance the area of absorption of water and nutrients.
Distal convoluted tubules (DCT) are simply formed by simple cuboidal epithelium. It is found in the cortex and corticomedullary junction.
Therefore, the type of epithelial tissue found in the proximal and distal convoluted tubules is the simple cuboidal epithelium.

During cell polarization, what are the two resultant edges called?
Answer:
The leading and trailing edge
Explanation:
Cutting the front edge of each wave's half cycle using leading edge dimming. Trailing edge dimming, on the other hand, eliminates the second half of each wave's half cycle.
~
During cell polarization, the two resultant edges are called the leading edge and the trailing edge.
What do you mean by Cell polarization?Cell polarization may be defined as a phenomenon by which cytoskeletal arrangement, extra- and intracellular signals, and organelle and membrane reorganization occur due to maintaining the cell shape.
Leading-edge works on the front edge and separates the half-wave cycle, while the trailing edge works on the back edge and cuts the second half of the wave.
Therefore, during cell polarization, the two resultant edges are called the leading edge and the trailing edge.

Carbohydrates are less-efficient fuel sources than fats because the carbon in carbohydrates is more:
Answer:Because complex carbohydrates are larger molecules than simple carbohydrates
Explanation:
Because complex carbohydrates are larger molecules than simple carbohydrates, they must be broken down into simple carbohydrates before they can be absorbed. Thus, they tend to provide energy to the body more slowly than simple carbohydrates but still more quickly than protein or fat.
how are utah and mexican praire dogs genes alike
Answer:
In terms of genetic variation, allelic richness (A) estimated through rarefaction resulted in 1.6–3.0 mean alleles per colony, and no private alleles were found. Mean genetic diversity (HE) was 0.525 (SD = 0.11), with values ranging from 0.276 (SD = 0.25) to 0.618 (SD = 0.09).
Explanation:
Utah prairie dog (Cynomys parvidens), and Mexican prairie dog (Cynomys mexicanus)—all of which may be considered rare (Hoogland 2006a). After 200 years of shootings, poisonings, conversion of habitat, and more recently plague, prairie dog numbers are a fraction of what they once were. Two of the species (Utah and Mexican) are listed as threatened or endangered under the Endangered Species Act (ESA).

how ribosomes help cell maintain homeostasis
Answer:
Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.
Explanation:
Hope This Helps
Have A Great Day
~Zero~
Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.
