Answer:
Try using a punnet square. Remember RR x YY = RY (Orange)
RY x RY = 1RR/ 2RY/ 1RR
Explanation:
use a 4 square punnet
Monohybrid cross will always be
1 RR / 2Heterozygous / 1 YY Genotype
1 Red / 2 Orange / 1 Yellow Phenotype
(In other cases 1 Domiant / 2 Heterozygous /1 Recessive)
The right option is; B. 7 major plates and many smaller plates
In the plate tectonics theory, the lithosphere is divided into 7 major plates and many smaller plates.
The plate tectonics theory is a scientific theory that explains that the Earth's lithosphere which is the rigid outer layer of the earth is made up of seven large continental and ocean sized major plates and many minor smaller plates. The movements of the plates are relative to each other and it usually ranges from zero to 100 mm per year. The interactions of the plates along their boundaries are thought to be the primary cause of majority of the earth’s seismic and volcanic activity.
Answer:
The different levels of biology are described below.
Explanation:
Biology can be studied at different levels from a single cell to the entire biosphere. The ladder from a single cell to the biosphere is known as the biological level of organization.
Following are the levels of organization:
A cell comprises of different organelles and is the main unit of life. For e.g bone cells
Tissues:
The cells combine to make tissues. For e.g the connective tissue
Organs:
Different tissue work together to make an organ. For e.g stomach
Organ system :
Different organs work together to make an organ system. For e.g The circulatory system contains heart and the blood vessels.
Organism:
Organ systems combine to make an organism. for e.g any human
Population
Group of organisms of the same species. For e.g a group of humans
Community
The different populations present in an area. For e.g all the plants, animals and microbes in an area.
Ecosystem
All the biotic as well as abiotic factors in an area make the ecosystem.
Biome
Different communities that can exist in the same climate.
Biosphere
Biosphere is all the life that exists on the planet earth and also all the abiotic factors present on earth.
yes, cell organelles can be seen with a microscope
