OA. secondary consumers
OB. primary consumers
OC.

OD
the Sun
Answer:
D. the Sun
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms in a food chain. Thus, producers are mainly known as the foundation of a food chain and are at the top.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
Most genetic diseases are caused by recessive alleles. Why? (1 point)

What is Restriction site?An isolated bacterial protein known as a restriction enzyme cleaves DNA at sequence-specific locations to create DNA fragments with a known sequence at each end.
For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.
There are at least 3,000 restriction enzymes, and they are all really cool. Each of these enzymes snips a certain DNA sequence, regardless of whether the DNA comes from a mouse, a bacterium, a fungus, or a human.
Therefore, The DNA strand above is cut with a restriction enzyme at the restriction site 5’-GAATTC-3’. The enzyme makes a staggered cut between the two T’s of the restriction site is GAATTC.

Earth's atmosphere blocks short wavelengths of the electromagnetic spectrum.
Which telescopes must be placed in orbit around Earth in order to observe short-
wavelength radiation?
Answer:
B hope this helps
:)
Explanation:
The study of chemicals and bonds is called chemistry.
The correct answer is B.
A wave is defined as a propagating dynamic disturbance of one or more quantities, sometimes as described by a wave equation.
The Data is given in the diagram of the question.
The visible waves are those waves by which it can help to see anything in the atmosphere and to see that thing we used a telescope to see in the universe. To see the things in the visible rays we have to use the visible telescope.
Hence, the correct answer is B that is a visible light telescope.

Explain the trigger that starts the breakdown of glucose.
Your liver releases stored glucose (glycogen) into circulation after being prompted by glucagon to transform it into a usable form.
What is a breakdown of glucose?Glycogenolysis is the name of this process. Additionally, glucagon might stop your liver from absorbing and storing glucose, keeping more of it in your blood.
A metabolic process called cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration.
The amount of insulin secreted by the pancreas determines how quickly glucose and carbohydrates are used. With the exception of liver and brain cells, the quantity of glucose that may diffuse in cells is often limited.
Therefore, the liver releases stored glucose (glycogen) into circulation after being prompted by glucagon to transform it into a usable form.

The type of evidence that scientists use to infer ancestry includes morphological, molecular, and embryological evidence, and the fossil record.
What is evolution?
Evolution can be used to describe descendence from a common ancestor of two or more species.
The presence of homo-logous structures is indicative of common ancestry between different species.
These homo-logous structures can be observed during the embryo stage of organisms and the observation of the fossil record.

Which of the following are enzymes involved in DNA replication? helicase DNA polymerase ligase all of the above
Answer:
All of the above
Explanation:
Helicase separates the two DNA strands to prepare them for replication. Without helicase, no replication would be possible, as the amino acids would not be accessible to be copied.
DNA polymerase is on the front lines of replication, directly copying the leading strand all at once. Because the lagging strand cannot be replicated in the same way due to its 3' to 5' orientation. DNA polymerase replicates in fragments while other enzymes fill in the gaps.
Ligase binds these fragments together to form a complete strand.
