17 Some Birds with shorter beaks enter into a population of birds with much
longer beaks, resulting in the hatching of birds with in-between sized beaks.
Which No evolutionary mechanism are most likely responsible for this
scenario
A mutation and genetic drift
B natural selection and artificial selection
C gene flow and recombination of genes
D artificial selection and crossing over during melosis
The evolutionary mechanism that are most likely responsible for this scenario is:
C gene flow and recombination of genesAccording to the given question, some birds are said to have shorter beaks and when they mate with birds that have longer beaks, they produce offspring that have in-between size beaks.
The evolutionary mechanism that is in charge of this phenomenon is simply gene flow and recombination of genes. This is because there is a combination of genes from the parents and given to the offspring.
The shorter beaks and the longer beaks of the parents combined and the offspring got in-between beaks.
Therefore, the correct answer is option C

if 10% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides contain each of the other three bases
Cytosine-
Adenine-
Thymine-
Answer:
Cytosine: 10%
Adenine: 40%
Thymine: 40%
Explanation:
So we know that Cytosine and Guanine are complementary and Adenine and Thymine are complementary.
Cytosine would be 10%
What's left is 80%, which would be divided by two because adenine and thymine have the same percents.
Adenine: 40%
Thymine: 40%

What are the sex chromosomes? Explain how it is shown in male and female; and karyotyping
Answer:
Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
Explanation:
Sex chromosomes are chromosomes which are responsible for sex determination. These are the X and Y chromosomes. Females have two X chromosomes and males have one X and one Y chromosome in their sex cells/gametes. Karyotyping is the visualization of chromosomes after blocking the cells in mitosis and staining; this allows us to identify the size, shape, and number of chromosomes present in cells, which is significant because extra, missing, or abnormal chromosomes can cause developmental problems or issues with body functions.

Because cilia cannot function properly, smokers have a frequent headache.
True
Answer:
Explanation:
The cilia sweep out mucus and dirt so your lungs stay clear. Smoking temporarily paralyzes and even kills cilia. This makes you more at risk for infection. Smokers get more colds and respiratory infections than non-smokers.
Because cilia cannot function properly, smokers having a frequent headache is a true statement.
What is Cilia?These are tiny hair projections which are found in the airway of the body and helps to prevent dust or foreign matter from getting to the lungs.
Smoking destroys it and leads to insufficient oxygen inhaled by the body as a result of presence of contaminants which may therefore lead to headache.

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

Answer:
large central vacuole
Explanation:
mature plant cell contains large vacuoles while a animal cell has small vacuoles
A mature animal cell is different from a mature plant cell because of the plant cell has differentiation ability.
Mature plant cell can still divide and differentiate to produce a complete new plant.
The mature animal cells cannot differentiate into the other cells to produce all the different cells that can form a complete animal.
