Explain the three events in sexual reproduction that contribute to genetic variation in a population.
The variety in DNA sequence seen in each of our genomes is referred to as genetic variation.
What is Genetic Variation?
We are all different from one another in terms of our hair color, complexion tone, and even the form of our features due to genetic variance.
The role of genetic diversity in evolution is crucial. Genetic variety that is passed down from one generation to the next is what drives evolution. Favorable traits are "selected" for, persist, and are transmitted. Natural selection is what causes this.
Mutations are adjustments made to the genetic code. (For the majority of life, this entails a change in the DNA sequence.) A single mutation can have a significant impact, but evolutionary change frequently results via the accumulation of many small-impact mutations.
Therefore, The variety in DNA sequence seen in each of our genomes is referred to as genetic variation.

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.

When Mendel crossed the P
(parent) generation, what did
he call the generation
produced by the P
generation?
re
A. P2
B. F1
C. F2
Answer:
B. F1
Explanation:
Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.
A mature plant cell is different from a mature animal cell because the plant cell has?
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.
Therefore, A mature animal cell is different from a mature plant cell because of the plant cell has differentiation ability.

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

Answer:
Explanation:
In a eukaryotic cell, almost all transcription occurs in the nucleus and translation occurs mainly at ribosomes in the cytoplasm. In addition, before the primary transcript can leave the nucleus it is modified in various ways during RNA processing before the finished mRNA is exported to the cytoplasm.
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%
3. Design and describe an experiment using celery stalks to demonstrate how certain conditions will cause a loss or gain of turgor pressure. In order to follow the scientific method, your description should start with an observation and be followed by (i) a testable hypothesis, (ii) an outline of the experiment that will test the hypothesis, (iii) a description of the type of data that will be collected, and (iv) a possible conclusion that could likely be made after completing the experiment
Answer:
Explanation:
A way you can use celery stalks to demonstrate the conditions with loss or gain of turgor pressure, is by setting us the same situation with water. I. You could possibly make a chart with how the celery could change. II. Testing the different out comes of the celery changing and what it has done and if it matches the hypothesis. III. The type of data you could conduct would be is seeing the height, length, and width. As wellas trying to see how much celery would soak up. IV. A possible conclusion of that experiment would be that the celery stalks would all expand expect for the one not in any water and it all would possibly start to grow into more than one celery and sprout. H2OH2O
Turgor pressure is the pressure due to fluid in a cell, that provides a force making the plasma membrane to push upon the cell wall
The responses and reasons for the experiment demonstrating the conditions by which turgor pressure is lost or gained are as follows:
Observation: Cut celery placed in water are fresher and are not as wilted than cut celery placed on a table without water, or placed in a salt solution
(i) A testable hypothesis is given as follows;
Hypothesis: The turgor pressure is gained by increasing the hypotonicity of the water that the celery stalks is placed into
(ii) An outline of an experiment to test the hypothesis is presented as follows;
Procure three celery ticks and three beakers that can contain a stick eachPlace 100 mL fresh water from the tap into one of the beaker, 100 mL of 5% salt solution into the second and 100 mL 10% salt solution into the third beaker, and label the beakersMeasure and record the mass and sizes of celery stalk lengths cut to 5 cm length and identically sized, after which they are placed one each into each beaker Take a picture of the sticks in the containers that shows the sizes of the sticks, and also write a note describing each stick in the lab notebookPlace the containers into the fridge overnightMeasure and record the parameters of the sticks removed from the fridge and take a picture of the sticks with a ruler by the side of the container to show the size of the sticksRecord the observation(iii) A description of the type of data that will be collected include, the width, mass and length of each celery
(iv) A possible conclusion that could likely be made after completing the experiment is that the gain in turgor pressure is directly related to the hypotonicity of the solution the stick of celery stalk is placed
