Why is the distinction between crude density and ecological density necessary?
Answer: Crude density includes all the land within the organism's range whereas Ecological density includes only that portion of land that can actually be colonized by the species.This variation in density is important to both the species in question and its predators.
Explanation:
Answer:
This called crude density. ... Density measure in terms of the amount of area available as living space is ecological density. Crude density includes all the land within the organism's range whereas ecological density includes only that portion of land that can actually be colonized by the species.

Answer:
Predators can be omnivores.
Explanation:
Predators are animals that hunt and kill other animals for food. Only animals can be predators.

Explain how an action potential and graded potential are different
Answer:
Graded potentials are brought about by external stimuli (in sensory neurons) or by neurotransmitters released in synapses, where they cause graded potentials in the post-synaptic cell. Action potentials are triggered by membrane depolarization to threshold.
DNA polymerase and RNA polymerase are enzymes. They belong to the macromolecule category
Answer:
Catalysts
Explanation:
Both catalyze the reactions
DNA polymerase and RNA polymerase are enzymes. They belong to the catalyst category.
What type of macromolecule is RNA polymerase and DNA polymerase?
RNA polymerase is an enzyme that creates RNA and catalyzes the initiation and elongation of RNA chains from a DNA template.
RNA is formed by a process known as transcription.
DNA polymerase is a type of enzyme that is responsible for creating new duplicates of DNA, in the form of nucleic acid molecules.
Nucleic acids are polymers, which are big molecules produced up of smaller, repeating units that are chemically related to one another.
Thus, DNA polymerase and RNA DNA polymerase and RNA polymerase are enzymes. They belong to the catalyst category.

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells.
Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication
Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.This process (crossing over) occurs in Meiosis I, specifically during Prophase I.Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

USE PICTURE ABOVE!! NEED ANSWERS ASAP!!! 8. Categorize What types of bonds are present in
this molecule?
9. Analyze What elements are present in this
molecule?
10. Solve What is the chemical formula of this
organic compound?
Answer:
Explanation:
The structure represented in the picture attached to the question is a benzoic acid (which is an organic compound).
8. The type of bond present between the carbon-carbon, carbon-hydrogen and carbon-oxygen atoms in the compound (same as other organic compounds) is a covalent bond. This is because oxygen and hydrogen share there valence electrons with carbon; oxygen has two valence electrons and thus it is surrounded with two bonds and hydrogen has one valence electron and thus surrounded with one bond.
9. The elements present in this compound, as can be seen in the picture, are carbon, hydrogen and oxygen which is the reason it is referred to as an organic compound.
10. The chemical formula of this organic compound is C₆H₅COOH. The "cyclic" structure (aromatic structure) there shows that it is a derivative of benzene (because of the presence of the alternating double bonds) while the carboxylic group there has to be written separately in the formula.

The eyes, part of the nervous system, send messages directly to the arm muscles to swing the bat.
B.
The eye and arm, both part of the nervous system, tell the spinal cord to swing the bat.
C.
The brain and spinal cord, both part of the nervous system, direct the muscles in the arm to swing the bat.
D.
The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
What is brain?
The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath. This arrangement is reversed in the spinal cord, where the gray matter is located within and the white matter is on the outside.
Therefore, The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
