"Cell membrane" Outermost layer surrounding the cytoplasm.
Ray Of Light [21]3 years ago
3 0

Answer:

The correct answer would be the cell membrane.

The plasma membrane or cell membrane is a semi-permeable membrane which forms the outer covering of the cell.

This membrane is made up of a phospholipid which provides it with its semi-permeable nature.

Due to its semi-permeable nature, it controls the movement of substances inside and outside the cell.

The MOST distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is
Ugo [173]

The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.

<h3>What is the Y-5 molar pattern?</h3>
  • This is a distinctive type of molar teeth pattern found in apes and hominoids.
  • In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
  • Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
  • A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
  • In bilophodont pattern the tooth is divided into 2 symmetric sections.
  • The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

Explain how precipitation affects which plants grow in a area?​
MAVERICK [17]

Answer:

Percipitation helps plant growth because when the water falls, the plants suck the water up through the roots when the water seeps through the dirt that the plant is in, once the water is in the plant, it benefits the plant because without it, the plant will shrivil up and die

Hope this helps ;)

identify the types of questions that interest behavior geneticists, and describe the elements of heredity: chromosome, dna, gene
baherus [9]

The interaction between genetics and environment and how this affects behavior, resulting in individual variances, is of particular interest to behavior geneticists.

The environment in this context refers to every external, nongenetic component of our life, including prenatal nutrition and the people and objects in our immediate surroundings.

Chromosomes:

Each of our cells contains 46 chromosomes, 23 from our mother and 23 from our father. Chromosomes are complicated, spiraling molecules formed of DNA that resemble threads and contain genes.

DNA:

We have over 30,000 genes, which are DNA segments that, when activated (expressed), serve as templates for the synthesis of different protein molecules, which serve as the foundation for our physical and behavioral growth.

Genome:

The entire collection of instructions for creating an organism, included in all of its chromosomal genetic material, is called an organism's genome.

Gene:

Combinations of mutations at certain gene locations serve to distinguish us from one another. The majority of human features are not controlled by a single gene acting alone, but rather by a number of genes working together.
