Answer:
There are 2 sex chromosomes – X and Y. Females have 22 autosomes and two X chromosomes, i.e., 22 + XX, while males have 22 autosomes and an X and Y chromosome each, i.e., 22 + XY. hope it helps.
basically 22
Explanation:
Answer:
Explanation:
Lower frequency for both dewlap extension and pushups. In the presence of predators and females an increase in the dewlap frequency and pushups is expected as a result of defense and breeding mechanisms mixed while in the second situation we have just breeding mechanisms involved
The organism can produce 12 genetically different gametes.
<h3><u>Explanation:</u></h3>
The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.
Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.
Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.
So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
Answer:
b. False
Explanation:
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). These intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Hence, during respiration, most ATP is formed as a direct result of the net movement of protons down a concentration gradient but not potassium against a concentration gradient potassium.
