Answer:
A. decomposers
Explanation:
In a food web, all arrows should point to decomposers
What describes the goal of genetically engineering crops?
Answer:
Genetically modified crops (GM crops) are those engineered to introduce a new trait into the species. Purposes of GM crops generally include resistance to certain pests, diseases, or environmental conditions, or resistance to chemical treatments (e.g. resistance to a herbicide).
***8 Points*** Two copies of a ______ allele are needed to produce a trait.
When gases trap heat in the atmosphere causing the temperature to rise this is called the greenhouse effect.

B. False
Answer:
A. True
Explanation:
Gases trap the heat in the atmosphere causing the temperature to rise, this is called the greenhouse effect.
What did Mendel discover
that true-breeding pea plants
do when allowed to self
pollinate?
A. They seldom have offspring with the
same traits as the parent plant.
B. They always have offspring identical to
the parent plant.
C. They always have offspring that
differed from the parent plant.
Answer: B. They always have offspring identical to the parent plant.
Which would a chemoautotroph use to produce energy?
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

Which statements describe hormones in plants? Check all that apply.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.
(i know that the first 4 are not right and neither are A, B, and D (1, 2, 4)
Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.

Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.
What does helicase do?
Answer:
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid
