Answer:
Nucleus and acrosome
Explanation:
Human sperm is the male gamete or sex cell formed by spermatogenesis. It is made of a head, neck, a middle piece and a tail. The sperm head consists of a haploid nucleus and anterior to nucleus, an acrosome. The nucleus contains DNA and nuclear protein and it transfers genetic features from the male to the next generation. The acrosome contains an important enzymes, hyaluronidase and acrosin. These enzymes help to enter head into an ovum.

Answer:
population density
population distribution
age structure
Explanation:
if we look at this question; it looks glaring that it correlates with a fill in the blank type of question.
So, from the question:
Frank counts 56 maple trees living on a 20-acre tract of land, and the data allows him to calculate the <u>population density</u> of the maple trees on the land.
In an ecological succession, population density refer to species of a common genera in specific geographical setting. It helps to measure the exact number of organism inhabitant a unit area of a place.
He observes that most of the maple trees grow closely together in groups of 6 to 8 trees, which describes the <u>population distribution. </u>
Population distribution is the spread of organism over a region in a geographic ecological setting. The pattern of distribution of organism may be uniform , in some organism they are largely dispersed and in some they are clumped together.
The<u> age structure </u>of the maple trees shows the percentages of trees of different ages.
The age structure is also a term used in ecology which is normally use to predict the proportion of growth of organisms. Age structure of species in the environment speaks volume about their distribution of age.
This question has choices namely:
preload
afterload
contractility
cardiac reserve
The correct answer is preload. Preload is the filling capacity of the heart and it corresponds to the volume of the blood that fills the ventricles during a cycle. In this case, the left ventricle needs to accommodate the increased volume from the right heat therefore increasing the filling capacity therefore the preload.
Afterload is the pressure that the heart needs to overcome to pump the blood. In the right ventricle, the pressure is the pulmonary arteries wherein the right ventricle needs to contract and generate a pressure greater than the pulmonary arteries for the blood to move out the ventricle. Similarly, in the left ventricle, the source of pressure is the aorta and the left ventricle needs to contract and generate a pressure greater than the aorta and the systemic circulation for the blood to move out of the ventricle.
Contractility is the force of contraction of each ventricle in one cycle.
