Answer:
c
Explanation:
B. incomplete dominance
C. multiple alleles
D. polygenic
Answer:
The most appropriate polygenic.
Polygenic trait refers to the trait which is controlled by two or more genes.
For example, height and skin color.
In the given breed, the phenotype of fur color is controlled by the interaction of two genes; gene B and gene E.
Thus, it is an example of polygenic inheritance.
A. salí
B. salimos
C. salisteis
D. salieron
6. How would you say "I visited Carlos" in Spanish?
A. Visité a Carlos.
B. Visitó a Carlos.
C. Visitamos Carlos.
D. Visitan Carlos.
Answer:
Africa needs to urgently put a number of additional measures in place to speed up these advances, and to move towards eliminating the disease. These include accelerated investment and deployment of vaccines, new diagnostic tools, new funding strategies for malaria control and keeping in check the drug and insecticide resistance challenge.
Explanation:
The cell membrane is also called selectively permeable membrane for its composition, it is composed of amphipathic lipid, protein and small amount of cholesterol which form a bilayer structure allow only specific substance.
The cell membrane is a thin selectively semi-permeable membrane and act as an outer covering surrounding cell cytoplasm, Proteins and lipids are the major components.
The major lipids are phospholipid, which form a semi-permeable lipid bilayer which have both hydrophilic or water loving head group and hydrophobic or water hating tail group and form bilayer structure.
Hence both group can interact with polar and non polar molecule individually called as amphipathic in nature, Some organelles like nucleus and mitochondria also have its own cell membrane.
The proteins are peripheral, extrinsic and intrinsic type and the function of cell membrane is to protect the cell and maintain the structural integrity of the internal environment of the cell.

The cell membrane is also called selectively permeable membrane for the sole reason being it is selective in nature.
It forms a physical barrier and as a barrier between the cell and the external environment as it allows only selected necessary molecules to pass through it and at the same time prevents entry of unwanted / unnecessary substances.
It also regulates the entry and exit of molecules into and out of the cell.
The cell membrane permits the entry of vital molecules like
water, oxygen, amino acids and glucose into the cell as they are crucial for various life processes and at the same time metabolic waste products are expelled through the cell membrane.
Answer:
chloroplast.
Explanation:
Chloroplasts are specialized organelles found in plant cells and some other organisms, such as algae. They are responsible for carrying out photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into glucose (energy) and oxygen.
Chloroplasts have a double membrane structure and contain their own DNA and ribosomes. They are green in color due to the presence of chlorophyll, a pigment that captures light energy for photosynthesis.
The presence of chloroplasts in plant cells allows them to produce their own food through photosynthesis, whereas animal cells do not possess chloroplasts and rely on obtaining nutrients from external sources.
In summary, chloroplasts are organelles found in plant cells but not in animal cells. They play a crucial role in photosynthesis, enabling plants to convert light energy into chemical energy and produce their own food
