Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY. This theory is not now accepted.
Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.
Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.
Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

16. Which organelle may have allowed early eukaryotes to make food and produce oxygen? (a) the Golgi apparatus (b) the central vacuole (c) the plastids
Answer:
the plastids
Explanation:
Answer:
The plastids are the organelles that compose the cells of plants and algae. These contain chloroplasts, which allow them to capture energy from sunlight. If they are ever removed, these cells will eventually lose their ability to photosynthesize food without help from another organism - they have lost an essential organelle. Without the presence of this organelle, eukaryotes may not have been able to use sunlight as a mechanism for producing oxygen or making nutrients such as glucose available for consumption.
The organelle that may have allowed early eukaryotes to make food and produce oxygen is the plastid. The correct option is c.
What is plastid?The organelles that make up the cells of plants and algae are called plastids. These have chloroplasts, which enable them to absorb solar energy. These frequently include several kinds of pigments that can alter the color of the cell as well as pigments that are employed in photosynthesis.
These cells will eventually lose their capacity to photosynthesize food without the assistance of another creature if they are ever taken out since they have lost an important organelle.
Eukaryotes might not have been able to exploit sunlight to produce oxygen or make nutrients like glucose available for consumption without the presence of this organelle.
Therefore, the correct option is (c) the plastids.

The input of sewage, fertilizer runoff, and animal waste can cause the formation of Choose one: A. an algal bloom. B. nutrient-poor soil C. fertile farmland. D. an artesian well.
Answer:
An algal bloom.
Explanation:
The input of sewage, fertilizer runoff, and animal waste can cause the formation of an algal bloom (abundances of cyanobacteria) because of the excess nutrients (nitrogen or phosphorus). If there are too much nutrients in the water (caused by the sewage, fertilizer runoff, and animal waste) it creates a perfect environment for excess growth, being an algal bloom. Algal blooms are toxic and are known to be harmful to the animals that rely on this source for their survival and humans as well.

Answer:
B) Mushroom --> Heterotroph
C) Algae --> Autotroph
A) Autotroph --> Producer
D) Hetrotroph --> Comsumer
Explanation:
Mushrooms are decomposers because like other fungi, they break down dead and decaying matter to make their own foodProducers, such as plants and algae, acquire nutrients from inorganic sources that are supplied primarily by decomposers whereas decomposers, mostly fungi and bacteria, acquire carbon from organic sources that are supplied primarily by producers.Primary producer; organisms, such as plants and phytoplankton, that can produce their own food through photosynthesis or chemosynthesis; also called autotrophs.Consumers are also referred to as heterotrophs in contrast to autotrophs, which are the producers of the food chain. Consumers therefore include animals and heterotrophic bacteria and fungi. Plants that are carnivorous and therefore consume organic matter as well are regarded as both consumers and producers.Have a great day! :D

The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside? osmosis diffusion passive transport active transport.
Answer:
It's active transport
Explanation:
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
What do you mean by Ion uptake?Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.
Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
