Answer:
An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. ... Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination.

Which statement describes the movement of water when a cell shrinks and shrivels due to osmosis?
Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
The cell membrane used energy to move water into the cell through passive transport.
The cell membrane used energy to move water out of the cell through passive transport.What area on the Iberian Peninsula maintained independence after the Reconquista?
Answer:
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.

Explanation:
What supports, protects and maintains the shape of the cell? *Very rigid. *
A .golgi apparatus
B. cytoplasm
C. endoplasmic reticulum
D. cell wall
Answer: D. the Cell wall
Explanation: The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
Also it is also a ridged layer found outside of the cell membrane

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
Answer:
What can be concluded about this genetic mutation is that it is inherited as a dominant trait.
Explanation:
In the case that one of the parents has a mutation whose inheritance pattern is dominant —which is rare— all the descendants will have the same mutation, since this gene will necessarily be expressed.
A dominant allele is one whose presence produces the phenotypic expression of the characteristic it determines. When the mutation is dominant, it will always be expressed in the descendants.
Hungtinton's disease and achondroplasia are examples of mutations with an autosomal dominant inheritance pattern.
The monohybrid phenotype identifies
A) what it eats
B) where it is found
C) genes of offspring
D) how it looks
Answer:
C) genes of offspring
Explanation:
A monohybrid cross is a genetic cross between two individuals who have different genetic variation at one gene, resulting in different traits. For example, a cross between a plant with white flowers and a plant with purple flowers.
The phenotype of the offspring gives details about which trait is dominant and which trait is recessive.

1: Every single cell has a ________.
2:Explain the fluid mosaic model of the cell membrane.
1 every single cell has cytoplasm, cell membrane and DNA
2 The fluid mosaic are various observations regarding the structure of functional cell membranes .
Answer:
1: Nucleus
2: The fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.

four students drew different illustrations to show the flow of energy in a field ecosystem. Which of the illustrations below is most accurate?
The correct answer is the second illustration
Explanation:
Energy flows from one level or organism to another as one organism takes nutrients from another. In this context, the first level is plants including oats and these take nutrients from the sun and the soil to obtain energy. On the second level are herbivores including mice that feed on plants. These can be followed by other organisms such as carnivores, for example, foxes and even top predators. Finally, the last level is decomposers these include bacteria and other organisms that can obtain nutrients from plants and animals as they die and decompose.
According to this, the correct diagram is the second one because these shows accurately how energy flow from the sun to plants oats), then to animals (mouse), and finally the energy of plants and animals flows to the decomposers.
In mice, the ability to run normally is dominant and are called running
mice. The recessive trait causes the mice to run in circles and are called
waltzing mice. Black hair is dominant over brown hair. Cross a waltzing

What is the ratio of unaffected females to affected females? (remember to simplify the ratio if it can be simplified)
Answer:
2. Approximately 75% of cases are sporadic and males are usually miscarried. Therefore, when the mother is affected, 1/3 of the female offspring will be unaffected, 1/3 of females will be affected, and 1/3 of males will be unaffected.

why is deforestation a threat to Yellowstone National Park?
Answer:
Deforestation causes loss of animal and plant species due to their lack of habitat. A huge portion of animals and plant species live in forests so if we take that away from them how are they supposed to survive? Not only does deforestation threaten species known to us, but also threatens species we haven't even discovered yet.
Explanation:
This isn't necessarily for Yellowstone but for all national parks ^

The photo shows a single-celled organism.
Which sentence best describes what this organism will look like at the end of
its growth period?
A. The same single cell, but larger
B. Two cells, but half the size
C. A small ball of identical cells
D. Three individual cells in a row
Answer:
B. Two cells, but half the size
Explanation:
Single-celled organisms, which are also referred to as unicellular organisms, usually have a growth mechanism or process known as binary fission.
Binary fission is a an asexual reproduction process that involves the division of a mature parent cell into two identical daughter cells of equal sizes that are almost half of their parents cell.
The sentence that best describes how the single-celled organisms shown in the picture above will look like at the end of the growth period is: "b. Two cells, but half the size"
