Which of the following is an example of a feedback loop in the body of the nervous system sends a signal to produce hormones in the body produces adrenaline when a person is scared the thyroid gland reverses the action of the parathyroid gland the pancreas can be Endo crying or exocrine
Explanation:
Both the endocrine and nervous systems use chemical signals to communicate and regulate the body’s physiology. The endocrine system releases hormones that act on target cells to regulate development, growth, energy metabolism, reproduction, and many behaviors. The nervous system releases neurotransmitters or neurohormones that regulate neurons, muscle cells, and endocrine cells. Because the neurons can regulate the release of hormones, the nervous and endocrine systems work in a coordinated manner to regulate the body’s physiology.

During crossing-over...
Group of answer choices
genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.
nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.
Answer:
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.During crossing-over, the genetic material is exchanged between non-sister chromatids, resulting in new combinations of alleles. Thus, the correct option is C.
What is Crossing-over?Meiosis is the cell division in which crossing-over takes place. Crossing-over results into formation of recombinants with genetic material which is different from the parental cells. Crossing-over takes place in the pachytene stage of prophase I of Meiosis I. This is responsible for the production of variations in the organisms.
Crossing over or chromosomal crossover is the exchange of genetic material during the sexual reproduction between the non-sister chromatids of two homologous chromosomes which results in recombinant chromosomes.
Therefore, the correct option is C.

How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism
Answer:
if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual
Explanation:
A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

PLS HELP! how does the process
of nature selection would act
on the population's adaptation
thereby passing that adaptation
to the next generation
Answer:
natural selection acts by differential survival and reproduction
Explanation:
According to the evolutionary theory proposed by Darwin (1859), selection natural can be defined as the evolutionary mechanism of differential survival and reproduction by which individuals adapt and change over time. Natural selection states that individuals better adapted to their environments will have more chances to survive and reproduce, thereby having more chances to pass their genes to the next generation. Natural selection acts on any heritable phenotypic characteristic, while selective pressure is any environmental factor that influences an individual's survival/reproduction.

One important way in which the flow of energy through ecosystems is different from the cycle of matter
Explanation:
As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved.

The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... * 1 point
Answer:
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called phylogenetic tree
Explanation:
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.

1.0°FProperty of materials able to easily pass through
the plasma membrane
The membrane is basically semi-permeable, which means that some molecules can pass through but others cannot. Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, rapidly cross membranes.
What is a hydrophobic molecule?The term "hydrophobic" literally means "fear of water." Water is repelled by hydrophobic molecules and surfaces.
Oil and other hydrophobic liquids will separate from water. Hydrophobic molecules are typically nonpolar, which means that the atoms that comprise the molecule do not generate a static electric field.
Hydrophilic molecules are the ones that are usually attracted to water and basically dissolve well in polar solvents.
Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, cross membranes very quickly.
Because small nonpolar molecules like oxygen and carbon dioxide are soluble in the lipid bilayer, they can easily cross cell membranes.
Small uncharged polar molecules like water can pass through membranes, but larger uncharged polar molecules like glucose cannot.
Thus, these molecules can be easily passed through the plasma membrane.
