Out of the following given choices;
Multiple Alleles
Chromosomes
Carriers
Sex-linked genes
The answer is multiple alleles. While we are used to diploid organisms like humans having two alleles (on same loci of each chromosome of homologous paired chromosomes) for a particular gene, it is thus the case there are two alleles in a population that determine a particular trait. However, there can be more than two alleles in a population that determine a particular trait. Individuals in the population may have different forms of the allele for the trait (please note that a diploid individual can still hold only two alleles). This, therefore, means that they are more than two alleles in the population that determine a trait such as coat/fur color (or blood type in humans). These are what are referred to as multiple alleles. The alleles interact with different degrees of dominance over others alleles hence the various phenotypes formed form their interaction.
B. a very cloudy sky.
C. a clear sky.
D. a light snow.
Answer: B. a very cloudy sky
Condensation is a process in which the gaseous form of water is converted into liquid. It is very important for the water cycle. This results in the formation of the clouds, fog and dew. For the occurrence of condensation, the air must be saturated. Saturation occurs most commonly when the warm air in the atmosphere cools down to it's dew point. The condensed water vapors and some of the particular matter forms the clouds.
The ocean life would die off because less salinity in the water and if the currents decrease in strength the nutrients they carry would not make to the life in the oceans and ocean life would die.
B. somatosensory cortex, thalamus, spinal cord
C. thalamus, spinal cord, somatosensory cortex
D. spinal cord, thalamus, somatosensory cortex
The right answer is C. thalamus, spinal cord, somatosensory cortex.
The somesthetic system, or somatic sensory system, groups the nervous mechanisms responsible for collecting somatic sensations (the sensations of the body). This is the meaning that tells us
about the state of our body
on our environment, through our body.
Somesthesia is an integral part of different sensory modalities of perception as well as the specific senses of hearing, vision, taste, smell, balance.
It is composed of the somatosensory thalamus, spinal cord, and somatosensory cortical areas.

Mouse needs care from its parents after birth. So, the correct option is (C).
Mammals are a group of vertebrates in which the young are nourished by the milk of the special mammary glands of the mother. Mammals are distinguished by many other unique features such as hair being a typical mammalian feature but in some mammals such as whales, it has disappeared except in the embryonic stage.
The lower jaw of mammals is attached directly to the skull, rather than to a separate bone called the quadrilateral, as in all other vertebrates. A series of three small bones conduct sound waves to the middle ear while the muscular diaphragm separates the heart and lungs from the abdominal cavity.
Mature red blood cells (erythrocytes) in all mammals lack a nucleus, while all other vertebrates have red blood cells. All of them require care from parents after birth.
Thus, Mouse needs care from its parents after birth. So, the correct option is (C).

B)

C)
development of organs for transplantation
D)
studying the chromosomal changes during cell division
Answer:
The correct answer would be C) development of organs for transplantation.
Cell differentiation refers to a process by which a cell becomes specialized to perform a specific function. For example, a liver cell, blood cell, muscle cell et cetera.
In multi-cellular organisms, life starts with a single cell (zygote) which then divide and differentiate into various types of cells. The specialized cells synchronize to form tissue which then form a particular organ.
Thus, regulation of cell differentiation can lead to development of specific organ which can be used for transplantation.
Answer: C) development of organs for transplantation
Explanation: Stem cells are human cells that can develop into many different types of cells. Stem cell research includes regulating the process of cell differentiation and stem cells can be used in the development of organs.
