Answer: D) Polygenic
Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.

The polar region (arctic and antarctic circles) is cold all year and experiences low precipitation.
What is the polar region?Any location on Earth that lies between the North or South Pole and the Arctic or Antarctic Circles is referred to be a polar region. The Arctic Ocean and a portion of several nearby land masses are included in the northern polar area, sometimes known as the Arctic.
Extremely cold temperatures, heavy glaciation wherever there is enough precipitation to create permanent ice, brief and cold summers, and extreme variations in daylight hours, with 24 hours of daylight in the summer and total darkness in the middle of the winter, are all characteristics of polar regions.
Hence, the polar region (arctic and antarctic circles) is cold all year and experiences low precipitation.

Which of the following statements about the flow of energy in nature is not true?
A. A large amount of energy in food is needed for bodily function
B. A major portion of the energy from food is used to keep our bodies warm
Only a small portion of the energy from food is used to keep our bodies warm or for other bodily functions. Most of it is lost as heat or through other processes.
When answering questions on Brainly, it is important to always be factually accurate, professional, and friendly. It is also important to be concise and avoid providing extraneous details, while also taking care to address all parts of the question.
Typos and irrelevant information should not be ignored. In the case of the provided question, the answer is option B: A major portion of the energy from food is used to keep our bodies warm. This is not true in the context of the flow of energy in nature.
The flow of energy in nature involves a constant transfer of energy from one organism to another in an ecosystem. Energy enters an ecosystem through primary producers like plants, who convert sunlight into food through photosynthesis.
This energy is then transferred to herbivores, who are then eaten by carnivores. As energy flows through the food chain, only a small amount of energy is transferred from one trophic level to the next.
The majority of the energy is lost through respiration, heat loss, and other metabolic processes.

why do we need to use artificial feed in pond for fish culture
Answer: Artificial feed is commonly added to aquaculture ponds to enhance growth and survival of juvenile fish. ... Feeding also introduces excessive nitrogen and phosphorus into ponds, which promote growth of nuisance phytoplankton and cause reduced oxygen conditions from aerobic decomposition of feed. Artificial feed is commonly added to aquaculture ponds to enhance growth and survival of juvenile fish. However excessive feeding may decrease fish growth and survival by reducing water quality and natural prey populations.

The U.S.A. has built a station on Mars. Two new astronauts are to be sent on a mission to Mars to help maintain the Mars station. As they travel from the Earth to Mars their weight is monitored. What happens to their weight as they travel from Earth to Mars is carefully recorded. Which statement would you not expect to be listed? (Does not happen)
Group of answer choices
As they leave the Earth their weight decreases
As they get closer to Mars their weight increases as they get closer
Weight never changes
They are weightless in space during most of their journey
Answer:
Weight never changes & As they get closer to Mars their weight increases as they get closer.
Explanation:
If the new astronauts were traveling to Mars from Earth the first thing you would notice is that their weights would change, this is because there is little gravity in space so you would watch them become lighter as they go farther into space. As for the second answer, if you were getting closer to mars your weight would be less than the regular weight you would have on Earth this is because of Mars gravity being smaller than the gravity on Earth.
Water is split and oxygen is released in
A: photosystem I.
B: the Calvin cyde reactions.
C: the light-dependent reactions.
D: the electron transport chain.
E: the cydic electron pathway.
Answer:
C
Explanation:
This happens during photosythesis II. Where oxygen is released
Hope this helps!
Water is split and oxygen is released in the light-dependent reactions.
Photosynthesis occurs in two stages; Light phase and dark phase. The light phase involves the photolysis of water.
The photolysis of water is a light dependent reaction. In this reaction, water is splint into H and OH.
Hence, Water is split and oxygen is released in the light-dependent reactions.
