What are the sex chromosomes? Explain how it is shown in male and female; and karyotyping
Answers
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.

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
Answers
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

What materials do motor neurons need to survive and how do they get those materials?
Answers
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.

A parent with the blood type A (genotype AO) and a parent with blood type B (genotype BO) have children with blood types A, B, and AB. What type of inheritance pattern is shown by the child with type AB blood and why?
Answers
Answer:
Co-dominance because he expresses both of the alleles simultaneously
Explanation:
The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.
This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
The inheritance pattern is co-dominance.
The genotype of an individual is the sum total of the genes that the individual has received from parents. When two genes are expressed at the same time, the inheritance pattern is called co-dominance.
Hence, the child that has a blood type AB has both A and B expressed and this is co-dominance.

Answers
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:
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.
