What are the 2 laws Mendel came up with?
Mendel's Laws of Heredity are usually stated as: 1) The Law of Segregation: Each inherited trait is defined by a gene pair. ... 2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
Describe a situation in which a bacteria-free environment would be desirable: not desirable:

Tiger (Panthera tigris) and lion (Panthera leo) are the most closely related species among the other feline species.
What are feline species?Feline species refer to various types of cats or other members of Felidae family. This family includes both big cats as well as small cats, such as domestic cat and large tiger both come under this family. A total number of 40 species of felines are known today, where they are distributed in various habitats around the world.
Some common examples of feline species include the lion, leopard, jaguar, domestic cat, etc. Each feline species has their own unique characteristics that allow them to survive under their respective habitats.
The two feline species that are most closely related in the given list are tiger (Panthera tigris) and the lion (Panthera leo). They both belong to Panthera genus within the Felidae family. The other feline species are not closely related as the tiger and the lion.
Therefore, tiger (Panthera tigris) and the lion (Panthera leo) are the most closely related species.

Is soil necessary for secondary succession? (yes or no)
Answer:
Yes
Explanation:
The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.
Answer:
The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.
Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
Explain how the genetic disease called Sickle Cell Anemia is more prevalent in African- Americans compared to other races because of the Malaria Disease.
Answer:
Explanation:
This is because sickle cell disease is common in malaria dorminated area because their traits confers resistance to malaria. The red blood cells, which contain abnormal hemoglobin become sickle in shape after it has been affected by malaria parasite. Therefore, most American that have African ancestry are at high risk of
the disease because the African ancestry are carriers if this gene and are inherited by the Americans.
Which of the following explains the role of plants in the carbon cycle?*
(1 Point)
Plants transfer oxygen and carbohydrates in the biosphere to carbon dioxide in the atmosphere.
Plants transport carbon dioxide in the atmosphere to groundwater.
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Plants transfer oxygen in the atmosphere to fossil fuels.
Answer:
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Explanation:
Plants are unique organisms being that they have the unique ability to manufacture their own food via the process of PHOTOSYNTHESIS. Hence, they are called AUTOTROPHIC. Photosynthesis is the metabolic process by which plant cells make sugar (glucose) in the presence of sunlight.
However, in the photosynthetic process, plants require inorganic source of carbon called CARBON DIOXIDE (CO2) and water to perform the process. The chemical overall reaction of photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
This explains the role of plants in the carbon cycle as they help transfer carbon dioxide (CO2) in the atmosphere to carbohydrates in the biosphere (living organisms).

The honeybee has 32 chromosomes in their somatic cells. They undergo meiosis but can
produce offspring drones without fertilization. How many chromosomes does the drone have?
What does this mean for the drone?
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.

Which of the following is the most significant contribution DNA makes to the formation of an organism?
a)energy
b)support
c)information
d)matter
Answer:
C
Explanation:
information
The one that is the most significant contribution DNA makes to the formation of an organism is information. The correct option is C.
What is genetic information?Information about an individual's genetic tests and the genetic tests of an individual's family members.
Also information about the manifestation of a disease or disorder in an individual's family members, is included in genetic information (i.e. family medical history).
Genetic information includes your genetic tests as well as the genetic tests of your family members. Genetic information also includes any disease, disorder, or condition that your family members have.
All of the proteins that an organism will ever synthesize are encoded in the genetic information stored in its DNA. DNA is found in the cell nucleus of eucaryotes.
A DNA molecule is made up of two complementary nucleotide chains. The Structure of DNA Provides a Heredity Mechanism.
Thus, the correct option is C.

Select the correct answer from each drop-down menu. Dina is a paleoclimatologist. She wants to review documents to assess climate data for h
er hometown. Which historical documents should Dina examine in order to assess this climate data?
Dina should examine__________and_________to find historical climate data for her hometown.
Answer:
The correct answer is - newspaper articles and farmers' harvest yield records.
Explanation:
Paleoclimatologists are the people that study the ancient climate before the availability of the instrumental records or the data and therefore depend on the coral reefs or the rocks and also compare the current climate how dramatically different climate states occur in few decades.
Dina should examine newspaper articles to find out what type of climate was before and now in her hometown and she should also check records of farmer's harvest yield to get what type of weather and climate was there.
Answer:
The correct answers are:
- Newspaper Articles
- Farmers Harvest Yield Records

what role do wild Florida consumers play in the food web
Answer:
Other items in the internet, such as plants and/or each other, are 'consumed,' or eaten, by consumers. Pine snails, white-tailed deer, and some turtles and river rats will consume sawgrass in the Everglades. They then become food for another species, and the nutrition they gained from the grass is transferred to them.
Explanation:
Answer:
Producers Snake root ,Cypress Tree, Orchid Tree. Role of the producer:
A producer captures energy and stores that energy in food as chemical energy. Producers such as plants have special organelles called as chloroplasts that absorb energy from the sun.
Example: Autographs are producers, that make their own food by photosynthesis process.
Explanation:
In the Everglades, producers – mostly plants – produce energy and nutrients from the sun or through a chemical reaction. Then, herbivorous consumers – turtles, deer, and others – eat those plants for sustenance

Answer:
D
Explanation:
Millions of years ago, plants evolved from living in the water, to living on land. Name and describe the structures and mechanisms used by plants today to survive in a dry (land) environment.
Answer:
desiccation tolerance, alternation of generation
Explanation:
Adaptation to life on land, took place by desiccation tolerance that is the ability of the organism to stand or endure extreme dryness and the alternation of generations such as the life cycle changes in which the haploids and diploids change or show haplodiplontic. The development of the phloem and xylem tissues for distribution of water and intake up of minerals from the soil. Development of stem for gas exchange. Some plants have defense strategies for the dry environments such as seedless sprout growth.
